You don’t have to dumpster dive to know that supermarkets send a steady stream of uneaten food to landfills.

Once there, the waste does more than smell bad. It also contributes to climate change by emitting methane, a greenhouse gas that is around 30 times more potent than carbon dioxide. In fact, landfills are the third largest source of methane emissions in the U.S., according to the Environmental Protection Agency (one reason the USDA recently pledged to reduce food waste 50 percent nationally by 2030).

But when a new California state law [PDF] goes into effect this April, large grocery stores in the state will be required to ditch the landfill and compost or recycle their food waste instead.

In order for supermarkets to comply with the impending law, they’ll need more places to put the waste—and one Sacramento-based company appears to be well positioned to respond to this problem. California Safe Soil has developed a process that transforms truckloads of supermarket food waste into farm-ready fertilizer it calls Harvest to Harvest, or H2H.

“This was something that made perfect sense to me,” says CEO Dan Morash, who founded the startup in 2012, after leaving a career as an investment banker in the energy sector. “There’s this huge stream of waste from the supermarkets that is no longer safe to eat as it gets to the end of its shelf life, but it still has a lot of nutrients.”

Using fertilizer made from food waste also cuts down on the need for synthetic nitrogen fertilizer, he adds, which can reduce the amount of nitrate runoff into local rivers and streams, which often lead to dead zones.

The company claims that since its launch in 2012, it has diverted over 2.2 million pounds of food waste from the landfill, preventing the emissions of 3.2 million pounds of greenhouse gases and preventing the need for over 1.1 million pounds of nitrogen fertilizers.

Final Liquid Fertilizer ProductHow is Morash’s product different from standard compost? He worked with soil and fertilizer specialist Mark LeJeune to develop a method that fast forwards the composting process (which is fueled by aerobic digestion, or bacteria fed by oxygen that breaks down organic matter). The process turns food waste into liquid fertilizer in three hours.

First, the food is ground down into a liquid, then treated with enzymes to break down the protein, fat, and carbohydrates into the amino acids, fatty acids, and simple sugars. Then, it’s pasteurized (that is, heated at high temperatures) to kill any pathogens that might be present.

“The average particle size is very small—26 microns,” Morash says. “This [enables it to] mix easily with water.”

There’s a separate stream for organic and conventional food, as California Safe Soil sells an all-organic version. Both are applied to the crops via drip irrigation.

In 2012, Morash and LeJeune opened a pilot plant in Sacramento to develop the technology. The product was commercialized in 2013 and is regulated by the California Department of Food and Agriculture.

“The California Department of Food and Agriculture is concerned about food safety, so we had to prove that [the fertilizer production process] eliminates pathogens,” Morash says. “So we did a research project called a challenge test at the University of California, Davis.”

To show that the product was effective, the company conducted additional experiments with researchers, including one at U.C. Davis and a strawberry expert at U.C. Cooperative Extension.

Morash claims that use of his fertilizer on tomatoes has upped the rate of food production by between 10 to 15 percent.

California Safe Soil’s target market is mainly large farms that grow crops like strawberries, tomatoes, leafy greens, almonds, and wine grapes. Several of the berry growers that he works with supply for Driscoll’s, Morash says.

Broccoli TrialBut orchard crops like fruit and nuts are especially well suited for this liquid fertilizer. Traditionally, orchard-based farmers “need to till the soil to get organic matter in without cutting up the roots,” he says. “So the ability to deliver organic matter to the soil in liquid form is a big positive.”

At the moment, the company processes food waste from 15 stores across five supermarket chains (Grocery Outlet, Nugget, Safeway, SaveMart, and Whole Foods) in Sacramento. Six days a week, the plant processes about 3,750 pounds of food from between seven to eight markets a day (each brings in an average of about 500 pounds daily).

The Sacramento facility is operating at capacity, but he hopes to build others in the coming years. The idea is to locate plants, like the one Sacramento, near grocery distribution centers. This way, after delivering goods to the stores, the centers’ trucks can fill up with food waste for the trip home, Morash says.

There are additional economic and environmental benefits to locating California Safe Soil plants near distribution centers, he adds. Turning food waste into fertilizer not only saves grocery stores the fees associated with sending it to a landfill, but it also prevents the greenhouse gas emissions and extra transportation costs often needed to deliver it there.

“This has a very positive environmental impact across the board,” Morash says. “It’s going to increase the sustainability of agriculture starting right here in California.”

Farms without wildlife don’t produce safer food

Most leafy green lovers probably remember the moment when they became suspicious of spinach.

In 2006, an E. coli outbreak that killed three people and sickened about 200 more was traced to the cool-weather crop growing along California’s Central Coast. Despite the fact that federal and state investigators claimed it was not possible to determine exactly how the dangerous E. coli strain spread to the farm, cattle and wild pig manure were implicated as the sources of the bacteria.

The following year, the state’s farming industry pushed out the California Leafy Greens Marketing Agreement, a set of recommended practices based on previous guidelines issued by to U.S. Food and Drug Administration (FDA) to promote food safety on farms. Though voluntary, it covers over a dozen salad fixings (think spinach, arugula, kale, and several types of lettuce) and has since become widespread throughout the nation.

Simultaneously, many produce buyers began asking growers to clear areas near fields of any vegetation. As a result, the farm fields along the California coast changed radically after the outbreak, as farmers did away with wooded areas, medians, and hedgerows, and most farms became relatively sterile landscapes, aside from the crops.

Now a new study [PDF] is calling the efficacy of that practice into question.

“The bottom line is that removing habitat around farm fields is ineffective at making food safer from pathogens,” said Daniel Karp, a U.C. Berkeley postdoctoral researcher whose work is funded by The Nature Conservancy. “It has been shown in this region that there are a lot of benefits to surrounding vegetation as well, such as providing a home for pollinators, which are declining across the nation.”

The research—which was published yesterday in the journal Proceedings of the National Academy of Sciences (PNAS)—used three sets of industry data from 2007 to 2013 and mapped the results of 236,000 tests for E. coli and Salmonella on leafy greens, irrigation water, and rodents on Central Coast farms.

Karp and his collaborators found that among 57 farms in Salinas, Monterey, San Benito, Santa Clara, and Santa Cruz counties—the source of three-quarters of the the country’s leafy greens—the overall frequency of disease-causing strains of E. coli increased in the six-year period. But it turned out the prevalence increased the most where surrounding wildlife vegetation had been cleared away.

In areas that had kept some natural vegetation intact—a fact the researchers verified using aerial imagery—the team also found that the overall presence of disease-causing strains of E. coli and Salmonella did not go up.

Karp says that by looking to California as an example, the study results could have implications for all of America’s 4.5 million acres of farmland where foods eaten raw are grown, and the wildlife habitat that surrounds this land.

“Federal legislation [enacted] in 2011 will give the FDA the ability to regulate farming practices,” he said, referring to the controversial Food Safety Modernization Act that has yet to be implemented. “While it doesn’t require farmers to remove habitat, my worry is that these practices will spread across the nation as buyers will put pressure on their growers and won’t buy from them unless they remove wildlife habitat.”

The Wild Farm Alliance, a nonprofit organization that advocates for the importance of protecting native species through sustainable agriculture has expressed concern about the dangers of removing wildlife habitat near leafy green crops all along.

Karp points to ways that conservation, agriculture, and livestock can flourish side by side, such as maintaining natural habitat (like trees) as a buffer between livestock and leafy green fields. The vegetation could filter runoff from grazed lands in the soil, he said.

“Or you could plant crops that need to be cooked, like artichokes, corn or wheat,” as buffer between livestock and leafy greens, Karp said.

Another option that could possibly work, he said, is to fence off waterways upstream from leafy green fields in order to prevent wildlife and cattle from defecating in the stream, which might eventually transport the feces downstream.

“We need to talk about how we can manage farming systems that both produce food and livestock and conserve nature at the same time,” Karp said. “We need to think creatively.”

Figure from study: Promising practices include (1) planting low-risk crops between leafy green vegetables and pathogen sources (e.g., grazeable lands); (2) buffering farm fields with noncrop vegetation to filter pathogens from runoff; (3) fencing upstream waterways from cattle and wildlife; (4) attracting livestock away from upstream waterways with water troughs, food supplements, and feed; (5) vaccinating cattle against foodborne pathogens; (6) creating secondary treatment wetlands near feedlots and high-intensity grazing operations; (7) reducing agrichemical applications to bolster bacteria that depredate and compete with E. coli; (8) exposing compost heaps to high temperatures through regular turning to enhance soil fertility without compromising food safety; and (9) maintaining diverse wildlife communities with fewer competent disease hosts.

New kind of agrihood in Northern California takes root

Civil Eats | July 28, 2015

On land that once housed a tomato cannery, a new type of farm is slowly taking root.

The farm is a flagship feature of The Cannery, a residential development in Davis, California, slated for public unveiling next month. And it’s on of a growing number of agrihoods, planned communities that eschew golf courses and build homes around farms instead.

It might surprise some, but The Cannery will be the first* of a new generation of agrihoods in Northern California, an area known for its local food and farm culture.

Well-established examples of the model, such as Serenbe on the outskirts of Atlanta and Prairie Crossing outside Chicago, have been around for 10 and 20 years respectively. But they’re relatively new to the Golden State. The Rancho Mission Viejo development in Orange County plans to launch a farm in 2016, and plans for an agrihood on University of California land outside San Jose were also recently announced.

The Cannery will be also be noteworthy addition to the agrihood list because it is the first agrihood located on former industrial land. In addition, the Cannery’s farm will be managed by a nonprofit organization focused on educating students and would-be farmers—another unusual element.Cannery_pumpkinsplanted2

“Usually, agrihoods are taking over existing farmland, not reclaimed land,” says Mary Kimball, executive director of the Center for Land-Based Learning (CLBL), the nonprofit that’s gearing up to run the farm next year. The Center runs educational programs across California for students aspiring to agricultural and environmental careers.

Ed McMahon, a sustainable development expert at the Washington, D.C.-based Urban Land Institute currently tracks about 200 such projects nationwide (both complete and in development). He agrees that the model is unique.

The 100-acre development, located near the city’s downtown and the University of California-Davis campus, was the home of the Hunt-Wesson tomato processing plant (later taken over by ConAgra) from the early 1960s until 2000.

After several stalled efforts to build on the land by other developers, the city of Davis approved The New Home Company’s agrihood project in 2013. The project broke ground in May 2014. All 550 solar-outfitted homes in the development will be  located within 300 feet of a park or trail connected to the city’s bicycle path network. The Cannery is also the city’s first master-planned community in 25 years, according to Kevin Carson, the New Home Company’s Northern California division president.

“We didn’t just want to put in a community garden,” he said. “We wanted to put real value back in farming, and [we wanted] people to get out of their houses to visit each other. We want the residents of Davis to bike here for a picnic and a tour of the farm.”

This fall, the New Home Company will deed the Cannery’s farmland to the city of Davis. In turn, the city will lease it to CLBL, which  plans to make it one of several incubator farms managed by the organization’s graduates. Every few years, new farmers will rotate in and take over daily operations.

“It’s a model not just for California, but how these kinds of places can be reclaimed for innovative developments that have an urban farm,” Kimball said.

The farm, which occupies 7.4 acres of The Cannery, includes 210,000 square feet for growing crops, a barn, a farm house and a fruit orchard. The farmers will live offsite.

CanneryMapCLBL, which will receive $100,000 a year for three years from the New Home Company as seed money, plans to make it a working commercial farm specializing in organic vegetables. Kimball also expects that the farmers will establish a community supported agriculture (CSA) subscription service primarily for Cannery residents, and hold periodic tours or workshops for the community.

But residents shouldn’t expect the farm to be up and running shortly after they move in this fall, Kimball says. CLBL still needs to raise money for farm supplies and equipment—such as a tractor and drip irrigation tape, for example—and the incubator farmers have yet to be selected. The organization also plans to hire an employee who will serve as the farm’s community liaison.

And because the land was previously covered in concrete, Kimball says, the farmers will spend the first few years improving the soil. CLBL has trucked in a new layer of soil for starters. But the natural clay composition of the soil beneath will make it a challenging base for growing food.

“Environmental tests show that the soil isn’t contaminated,” Kimball said. “But for the first three to five years we’ll be doing a lot of reclamation and planting cover crops … we’ll also continue to add lots of manure to the soil to increase the organic matter.”

The New Home Company has planted pumpkins, tomatoes, and sunflowers on the lot for now, Carson said. And there’s also a 15-acre mixed use space at the Cannery that the New Home Company is currently marketing for lease. One possibility for the space, Kimball says, could be a public market of local artisan vendors similar to others that have sprouted around the country recently.

Agrihoods are a small part of the residential housing market—about 5 percent, McMahon estimates. But thanks to factors such as the popularity of farm-to-table dining and the rise of the grow/buy local movement, he says, the niche is growing by leaps and bounds.

The model is also attractive to builders, says McMahon. “You can create value at a low cost,” he said, adding that developers have found that onsite farms have had a greater impact on home sales than other amenities such as spas or swim clubs. “Ag is becoming a competitive differentiator in the development world.”

But the value of green space and the yearning for community, McMahon says, is also responsible for the strong pull towards agrihoods.

One example he pointed to was the Grow Community, a planned neighborhood on Bainbridge Island near Seattle. The developer was initially focused on creating “zero carbon” houses that produced as much energy as they consumed, but included a community garden as an afterthought.

The community garden ended up being the most important meeting place in the neighborhood. “This is where they hang out and talk with their neighbors,” he said. “It’s not just about growing crops. It’s about growing community.”

* A planned community called Village Homes brought gardens and edible landscaping to Davis residents in the 1970s, but it was not built around a working farm.

Are small farms in India the key to taking tea organic?

The Guardian US/UK | Feb. 5, 2015

EcoTeas organic tea plantation

When fourth-generation tea planter Ramesh Babu decided to leave his family’s plantation in the southeast Indian state of Tamil Nadu to start his own organic operation, people called him crazy.

“It was unheard of in our part of the country,” the 54-year-old said of his decision in 2006 to take on 10 acres surrounded by forest in the hill town of Kotagiri nearby. “Initially, when you stop using [chemical] fertilizer you have a big fall in your production, so that’s one major factor which keeps other tea growers from going organic.”

Though rewarding, establishing an organic tea plantation has been challenging, Babu admits. There weren’t any other organic tea planters nearby, so he had to learn everything from vegetable farmers before launching his EcoTeas estate. And because there aren’t many small tea factories in India, he had to design his own processing machinery – a costly undertaking that took seven years. Selling the tea leaves he and his family can’t process or hand-roll on their own was also tough, Babu says, as tea companies pay the same going rate for organic leaves as for conventionally produced leaves.

It’s a lonely road that has left the family-run operation in the red to this day, but it could be an important one. A Greenpeace India report – which has been challenged as “pseudo-scientific” by the tea industry – released in August found that more than 90 percent of the domestic packaged and produced tea contained pesticide residues (pdf).

Yet despite the roadblocks, organic tea production could be moving closer to the norm in a country that produces more tea than any other except China. In the past few months, the two largest tea companies in India – Tata Global Beverages and Hindustan Unilever, which together comprise over 50 percent of the domestic market – announced it would set up pilot studies with the government to test how their growers can phase out pesticide use.

In a statement, Hindustan Unilever said it plans to work with nonprofit agricultural advisor Cabi on the feasibility study and source all of its agricultural raw materials using sustainable crop practices by 2020. The company aims to launch the pilot in April, according to Greenpeace India campaigner Neha Saigal, but it’s not clear when Tata – the second largest tea company in the world (hit in recent years with reports that female workers had been trafficked into domestic slavery from a plantation in Assam) – plans to kick off its program, which also has a goal to achieve sustainable sourcing by 2020.

More details about the pilots aren’t clear, as the companies have remained tight-lipped. (Both declined to comment). But when the largest players in any industry take their first steps towards sustainability, it raises the question: could this pave the way for smaller producers to shift to organic cultivation too?

There’s a huge need to bring down barriers that make it harder for growers to go organic, according to Saigal, whose organization pushed for the pesticide-free commitment, and is now keeping an eye on the companies to implement the pilots. India’s regulations for pesticide use in tea aren’t straightforward or consistent from one jurisdiction to another, nor comprehensive, she says.

“Pesticide regulation in India is in shambles,” Saigal said. “What this shows is that you need a policy level change.”

“Growers aren’t aware of what they are using and what they aren’t using,” she added. “It’s the government’s job to make these small growers aware of what’s toxic and what’s not. It’s their job to create those support systems creating a knowledge base and having a system to transform that knowledge to use ecological alternatives.”

Greenpeace India is in talks with the Tea Board of India – the government-run body with the authority to crack down on these regulatory problems – about setting up a support system for small tea growers so they can move away from pesticides.

In September, the Tea Board (which did not respond to interview requests) issued the second version of its Plant Protection Code that listed the approximately three dozen pesticides approved for use in tea. Yet maximum residue levels had been set for just 10 of them, according to the document.

Government support is needed for organic tea production to thrive in India, Babu says.

“The government of India and the Tea Board have got to come up with a very supportive package for small tea growers,” he said. “This would mean giving subsidies to help small tea growers convert to organic.”

Babu has his own plan to jumpstart a new generation of organic tea growers in India. He expects his factory to be fully up and running in the next few months, which he believes will improve his financial position, since he’ll be able to produce up to 30 times more tea. Once that happens, he wants to teach other growers how convert to organic growing so he can process their leaves in his factory and start an organic growers association that could foster mutual support and push for higher payments for their leaves.

But Hope Lee, a business analyst who specializes in the hot beverages market for intelligence research firm Euromonitor International, says that small tea growers in India and other developing markets – such as Argentina, the Middle East, China and Kenya – face other challenges beyond their borders.

“They find it hard to export their product to developed markets because they don’t meet strict standards in developed countries,” she said. “Some companies in developing countries don’t have money to hire these expensive services [to test for pesticide levels] and they don’t see the short-term profit from it if they pay a lot of money for testing.”

But it also depends on how serious the national government is in promoting their tea exporting business and how they set their standards, she added.

“So this issue comes to the question [of] if Unilever or Tata have the resources to solve this problem,” Lee said. “Big companies like Twinings or Unilever or Tata – they can influence the government and they have the resources to train their suppliers and make their tea grow in a more sustainable way, but they need the cooperation of the local government,” she said.

Fair-trade and certification programs are used as additional strategies to move industries towards more sustainable practices. Yet Daan de Vries, the markets director at UTZ Certified, an Amsterdam-based organization, says that certification alone is not enough.

“In some places there’s value but it’s not the way to go to change markets,” he said. “Consistently, you’ll see no more than maybe 5% of people who would want to change their buying behavior based on sustainability claims or labels.”

Tea 2030 is an initiative that appears to be taking on a more comprehensive approach. Organized by UK-based nonprofit Forum for the Future, industry heavyweights like Unilever, Tata and Twinings have joined with the Ethical Tea Partnership, Fairtrade and Rainforest Alliance to identify challenges facing the tea industry, such as competition for land, climate change, natural resource constraints and living wage issues. (Starbucks also joined late last year).

A report released by the initiative last year lays out these challenges, along with principles for a sustainable value chain, which the alliance would like to see in action by 2030.

“Of course the individual companies are pursuing their own sustainability [initiatives], such as Unilever and Tata on pesticides,” said Ann-Marie Brouder, Tea 2030’s coordinator. “But there are some problems too big for individual companies to tackle…. We believe that if we’re going to make change, it needs to be owned by the tea sector.”

In the meantime, Babu continues to quietly push forward, all the while tending his tea plants and the trees he’s allowed to intersperse among the crop in direct opposition to the monoculture plantation standard.

“It’s something that cannot be approached in terms of a business,” he said. “It’s a change of the mindset.”

This stove cleanly burns plastic and charges a phone

TakePart | Mashable | Nov. 14, 2014

KleanCook stove

It’s no secret that the smoke spewing from open fires and from indoor coal-fired cook stoves is a silent killer in the developing world, and a contributor to climate change. More than 4 million people die each year from health problems related to inhaling carbon monoxide or particulate matter released from stoves that burn wood, biomass, or coal, according to the World Health Organization.

Despite a long-running government campaign to eradicate dirty fuels from households, the problem persists in China. But thanks to two young entrepreneurs, a new kind of cook stove—one that can cleanly combust small amounts of plastic trash and convert its excess cooking heat to electricity—could be on its way into kitchens across China.

“Smoke-related illnesses are a bigger issue than malaria or HIV,” said Jacqueline Nguyen, one of the entrepreneurs and a University of California, Berkeley, senior toxicology student. “It kills more than HIV and malaria worldwide per year.”

While Nguyen handles business and marketing for Energant, the company behind the device, her best friend, Mark Webb—a 2011 Berkeley graduate who studied biochemistry—designed the K2 cook stove.

The K2 reduces smoky emissions by 95 percent, according to tests Webb conducted. Using the excess heat created during operations, it can generate enough electricity to trickle charge a mobile phone. It has the ability to burn biomass briquettes cleanly as well.

It can also burn plastic and wood without toxic emissions as long as the material—which emits volatile organic compounds when burned—doesn’t exceed 8 percent of the mass being used as fuel, according to Webb.

The ability to burn plastic and wood cleanly is what distinguishes the K2 model from the KleanCook stove, the product Webb designed last year.

Webb got the idea for the K2 cook stove during pilot testing of the KleanCook model in the Philippines this past summer, when he and Nguyen noticed people cooking food over open fires all across the country—and burning plastic bags as a way to get those fires started.

“We decided to make the K2, which was centered specifically around being able to burn off all of the toxic material from this trash,” Webb said.

But because the two wanted the cook stoves to generate income for local people who would sell the devices for profit, they decided to target the Chinese market, as business costs in the Philippines were too high.

How does it work, and what differentiates it from other clean cook stoves?

The stove’s built-in fan has a geometric design and resembles the turbo fan of a jet engine. When the fan blows air into the fire, it creates forced convection, which makes the stove more fuel-efficient. Carbon monoxide is then converted to carbon dioxide.

The stove’s greater efficiency means that 50 percent less fuel has to be burned to create the same amount of heat, resulting in lower emissions, according to Webb. A patent is pending on the K2’s design.

The stove also contains a thermoelectric generator. When one side of the device is exposed to heat and the other is kept cool, an electric current is generated as the heat travels from one side of the generator to the other. That electric charge is then fed into a voltage regulator to produce a steady current.

Because it’s made from cheap metal, the stove costs only $16 to manufacture. Energant plans to sell the stoves to regional distributors for $20 to $25. In turn, the salespeople will sell the units at retail for $50—a price that Webb and Nguyen say the Chinese government has deemed an acceptable amount to charge based on disposable income.

The debut of the K2 cook stove could be timely, as recent reports from China indicate there’s been an increase in burning trash and plastic, which releases carcinogenic dioxins.

Webb and Nguyen’s clean cook stove venture attracted support from Berkeley’s Development Impact Lab after the pair won the lab’s “Big Ideas” student innovation contest with the KleanCook stove.

The development lab is one of seven university efforts funded by USAID via the U.S. Global Development Lab. That initiative gives money to seven centers at universities around the country that support students creating solutions to global problems such as climate change, food security, health, and poverty.

“Our whole market approach to the KleanCook was to have the cheapest possible thing that was the most scalable and can deliver electricity for devices,” Webb said.

KleanCook also won prize money from the Clinton Global Initiative University contest this past year, which allowed the entrepreneurs to fund KleanCook’s pilot testing in the Philippines.

Though the K2 cook stove—KleanCook’s more sophisticated sister—appears promising, it isn’t ready for market yet. Webb says Energant has a pre-manufacturing prototype that he’s tested for efficiency using a consumer carbon monoxide sensor that recorded the carbon dioxide output of the stove.

To win the confidence of Chinese consumers, he says K2 needs to be tested using validated equipment—something that Energant would have to pay for specialists to do at Beijing’s Tsinghua University.

The company hopes to raise $30,000 from an Indiegogo campaign to pay for the testing.

Why saving lemurs will save this country’s rainforests

TakePart | November 6, 2014

Lemur in MadagascarMore than 90 percent of Madagascar’s lemur population faces extinction. Now scientist say that could threaten the future of the African island’s rainforests.

What do lemurs do for rainforests? Poop in them. Because lemur droppings contain tree seeds, they’re one of Madagascar’s best tree farmers, according to a new study published in the journal Ecology.

The study tracked the seed dispersal behavior of the island nation’s largest lemurs and followed the growth of a rainforest tree called Cryptocarya crassifolia. The findings revealed that seeds dispersed via lemurs were 300 percent more likely to grow into saplings than seeds that just dropped onto the ground.

“Lemurs may play an important role as gardeners of Madagascar’s rainforest, but they are at risk of extinction across the island,” said Amy Dunham, an assistant professor of biosciences at Rice University.

Onja Razafindratsima, a graduate student of Dunham’s, was the lead researcher in the study. “Only by understanding what role they play in the ecosystem can we hope to understand what the consequences of their loss may be,” she said.

A Malagasy native, Razafindratsima conducted the study in Ranomafana National Park in Madagascar’s southeast region. She spent a year following 24 groups of lemurs to figure out where they were dispersing seeds in the rainforest and noted the amount of sunlight that fell through the rainforest canopy. She then studied how those habitats affected the probability of seeds sprouting and thriving.

“One particular lemur species—the red-fronted brown lemur—tended to drop seeds away from parent trees in places where there’s opening in the rainforest canopy,” Razafindratsima said. The red-fronted brown lemur also tended to eat more seeds than its lemur brethren, making the species the most effective at seed dispersal, she said.

The other two lemur species studied, the southern black-and-white ruffed lemur and the red-bellied lemur, also promoted rainforest growth by moving seeds away from the parent tree—where competition for sapling resources is fierce, and chances of seedling development are lower.

“These two lemur species greatly enhance the recruitment of this tree species and its ability to regenerate,” Dunham said.

But knowledge of how important the species is to Madagascar’s rainforests doesn’t change the grim prognosis for the declining lemur population, which faces habitat loss from slash-and-burn agriculture and hunting.

“Some of the actions that need to be done would be to protect more forest habitat, to increase regulations on mining and wood extraction, and to provide alternatives to slash-and-burn agriculture,” said Razafindratsima.

In February, a group of lemur conservationists published an article in the journal Science recommending local actions to address the population decline. Those included increasing protected areas managed by local communities, promoting greater ecotourism in Madagascar, and increasing the presence of field researchers.

While conservation is key, Razafindratsima and Dunham believe there needs to be a balance between lemurs and the needs of local villagers, who they say use slash-and-burn techniques on the rainforest to grow food to feed their children.

“It’s a difficult problem, because we have to consider not just the animals but the people who live around the rainforest,” Dunham said. “We need to be sensitive with both people and animals while we figure out ways to conserve there as well.”

The bugs that can save the bees

TakePart | October 29, 2014

honeybee_combHow do you stop deadly bacteria from decimating beehives? Sic a self-replicating, bacteria-devouring virus on it.

That’s what a Brigham Young University research study claims, bringing hope that a natural cure for one of the honeybees’ deadliest killers is possible.

The disease, called American foulbrood, has infected between 3 percent and 15 percent of all honeybee colonies worldwide. The bacteria attack bee larvae, wiping out hives in the process.

Beekeepers have tried antibiotics on infected hives, but the disease can come back stronger and more resistant to the treatment. Some end up burning entire hives to keep the disease from spreading through a colony.

But BYU undergraduate student Bryan Merrill may be responsible for finding a new microscopic savior to swoop in and save the bees.

The natural treatment Merrill discovered involves unleashing a phage, or bacteria-eating virus, on the bee larvae. Once established, the virus attacks bacteria and self-replicates until the job is done.

Merrill took his phage research to BYU microbiology professor Sandra Burnett, who oversaw his work over the past three years. The results were published in the journal BMC Genomics.

“Phages are the most abundant life form on the planet, and each phage has a unique bacteria that it will attack,” Burnett said in a statement. “This makes phage an ideal treatment for bacterial disease because it can target specific bacteria while leaving all other cells alone.”

To date, they’ve identified five types of phages as good candidates for fighting American foulbrood. A “phage cocktail,” which combines four or five strains, is being considered by the United States Food and Drug Administration to prevent infection in beehives.

If commercialized, the product could save the honey industry hundreds of millions of dollars a year and keep antibiotic-ridden honey off the shelves.

“Right now for American foulbrood, we only have antibiotics to treat them, and they’re not working well,” Burnett said in an interview.

So far, the disease has shown resistance to oxytetracycline, the standard antibiotic treatment, and oxytetracycline’s replacement, Tylan, Burnett said. Both antibiotics are unsafe for human consumption, meaning children and pregnant women can’t eat honey from treated hives, she noted.

What makes phages unique is their ability to modify their structure in response to bacteria that try to survive by changing over time.

A phage can multiply itself, so there are more of them to hunt down the bacteria, Burnett explained, and as soon as the host bacteria are gone, the phages vanish from the hive.

She’d like to see a commercialized solution available for home beekeepers as well as for the industry.

“If you look at beehives, it’s a 50-50 split from hobbyist small-scale beekeepers and large-industry beekeepers,” Burnett said.

The researchers are in talks with some companies about putting a single-phage product on the market, but they said more research must be done to determine if using different combinations of phages in a cocktail could also be effective.

Robotic plants could be coming to your garden

TakePart | October 24, 2014

plantoid600pxWhen looking at gardens, landscapes, or forests, it’s easy to focus on what’s visible. Flowers, green grasses, and large trunks are the pretty parts, but below the surface is where plants and trees show their smarts.

Roots spread out, hold fast to the soil, and transmit information to the branches above, telling them which direction to grow, how long to go, and when to drop leaves. They’re also incredibly efficient at piercing the soil.

It’s an intricate system, and now a group of Italian scientists have created a robotic plant that mimics nature’s root system to monitor soil pollution, prospect for minerals, and look for water.

Meet the first plantoid.

It’s made of artificial materials, embedded with sensors, and equipped with a computer chip, a plant robot designed to simulate a real-life tree—trunk, branches, leaves, and all.

But the real stars in this fake-plant show are the roots, which really “grow.”

“We want to use robotics systems to better understand the living systems we use as a model,” said Barbara Mazzolai, a biologist at the Italian Institute of Technology in Genoa. She’s spent three years designing the plantoid so it can copy the way plant root tips grow and move through soil based on what they find in the environment.

So how does it work?

A motor unwinds a spool of polypropylene filament inside the trunk. The root tips—which are made of Teflon—have nine sensors each that can measure a range of a soil conditions. Those include levels of water, light, gravity, temperature, and pH. The plantoid can also detect the presence of nutrients such as nitrogen and potassium.

The roots grow based on the information received from sensors via a microcontroller in the tip. If it works right, the plantoid could be used in agricultural fields to detect heavy metals such as mercury and cadmium.

“It’s like a new microscope that biologists can use as a platform to study natural systems,” said Mazzolai.

Her team has a few kinks to work out before we start sending plantoid Roombas into our gardens. The first hurdle is to get the roots to move and bend simultaneously. To do that, she says, they are looking for the right Velcro-like material for the filament.

“This is the most challenging part to solve,” she said. While the plantoid is not ready for commercialization, Mazzolai is asking companies to explore the ways it could be used in industry.

Some examples? In search and rescue missions, Mazzolai said, a plantoid could send out root hairs that would help to anchor rubble and keep it from falling.

Another application could be in the field of surgery, where the biomechanics of the root tip could be applied to an endoscope. It could grow and move inside the body without damaging tissue and might be able to release drugs, Mazzolai said.

In space, a plantoid root system could anchor spacecraft and act as an exploratory arm to sample soil quality on other planets.

Space lasers could help count the carbon for the trees

TakePart | September 10, 2014

redwood_forestLasers, 3-D imagery and outer-space surveillance sounds like cutting room floor fodder of a scrapped Austin Powers film, but it’s all part of NASA’s latest effort to map the Earth’s forests and gain a better understanding on climate change.

Dubbed Global Ecosystem Dynamics Investigation lidar—the nod to Star Wars may be entirely coincidental—the laser instrument will be designed to hitch a ride aboard the International Space Station. Once aboard, it will pump out large-scale 3-D imagery of forests. Lidar—the type of laser mapping tool that Google uses to guide its self-driving cars—will be deployed to measure the height and configuration of a forest’s canopy and undergrowth.

NASA and the University of Maryland hope the technology will give scientists a better picture of just how much carbon is stored in the Earth’s forests and the impact of logging on climate change.

“There’s an open question of what is the net balance between the amount of deforestation taking place and subsequent regrowth,” said Ralph Dubayah, a University of Maryland professor who is leading the GEDI project. “If we don’t know what that is, we don’t know what future atmospheric levels of CO2 are and it becomes hard to run climate models.”

With a 3-D picture—or fingerprint—of a forest, experts would be able to calculate the weight of its trees and figure out how much carbon they contain. About half of a tree’s biomass is carbon, according to Dubayah.

Armed with the new data, policy makers should be able to quantify the potential amount of carbon that could be released into the atmosphere by deforestation or forest fires. They then could determine what it would take to offset that release, such as by planting more trees.

Deploying lidar from space will be an improvement over the way forests are currently monitored.

Airplanes currently are used to shoot lidar lasers down into forests, thereby mapping the height and configuration of a forest’s canopy and undergrowth.

But the plane’s limited range restricts the amount of data that can be collected.

“From space, you can get access to essentially all the world’s forests,” Dubayah said. “Aircraft is expensive and if you’re in the middle of a rainforest, there are a lot of logistics involved in doing that. If you use lasers in space, you acquire much more data much more rapidly at cheaper cost.”

The GEDI system is still in development at NASA’s Goddard Space Flight Center and is slated for deployment in mid-2018. Dubayah hopes that the first batch of data will be available by 2019, with the program running continuously from the International Space Station.

“If we’re going to make any kind of policy changes in the U.S., one way to do that is by planting trees and running climate and land use models to look at potential scenarios,” Dubayah said. “It’s hard to run models forward in time that evaluate alternative policy scenarios if we don’t know what we’re starting with.”

Are you ready for a 35-year drought?

TakePart | August 29, 2014

drought_utahWith the American West losing an estimated 63 trillion gallons of groundwater over the past 18 months, it’s hard to imagine that the drought could get any worse.

But it just might.

A new study estimates that the possibility of a decade-long drought hitting the Southwest sometime this century could be as high as 90 percent. And there’s as much as a 50 percent chance of a mega-drought that lasts for 35 years or more, according to Toby Ault, a professor of earth and atmospheric sciences at Cornell University.

“This is only the beginning,” said Ault, whose research will be published next month in the Journal of Climate. “The further south you go, the drier the average conditions really are, and the risk is greater.”

It’s the first research that quantifies the risk of drought from reduced precipitation and drier conditions caused by climate change. Scientists conducted their analysis by incorporating historical data of past mega-droughts in the Southwest—such as the series of long-running droughts that struck the region between 900 and 1400—into computer models of contemporary climate observations.

The drought forecast in the Southwest—which the researchers define as Central to Southern California, Nevada, Southern Arizona, Southern Utah, New Mexico, Southern Colorado, and Western Texas—compares starkly with predictions for the northern states. Ault’s computer models indicate that Washington, Montana, and Idaho, for instance, face a decreased risk for drought over this century.

“Dry regions get drier, wet regions get wetter, and places on the edge are uncertain,” Ault said.

Making global predictions about drought is harder as less data is available for many regions outside the United States. “But even so, we saw that the Southwestern U.S. looks like it’s exposed to risks that are comparable to other parts of the world, such as parts of Africa, Northern Mexico, and parts of Brazil,” said Ault.

Researchers at Scripps Institute of Oceanography recently found that the earth’s surface in the West has risen 0.16 inches over the last year and a half as a result of losing 63 trillion gallons of water. Another report estimates that water levels in California’s three largest reservoirs have fallen 70 percent.

So what would a drought prolonged for 35 years or longer look like?

“Take the current drought and double it,” Ault said. “In Arizona, there’s been a drought that’s gone on and off for the last 10 years. Doubling that, it looks very challenging.”

Next up for Ault is to calculate how much snowpack and groundwater would be lost in a mega-drought. He also plans to determine how much water the Colorado River would lose during a decades-long drought.

Though his predictions focus on the risk of drought brought on by drier conditions from climate change, Ault says he’s still not sure if the West’s current drought is a result of global warming.

But regardless of the relationship, he emphasizes that people should pay attention to how drought is affecting the region.

“It’s a glimpse and preview of what we expect to happen from climate change—and a picture and window into the future,” he said.

Drought dowsing goes hi-tech

California Magazine | Aug. 11, 2014

Wellntel pilot

This year, groundwater is serving as California’s pinch hitter, supplying about 60 percent of the state’s needs during this historic drought. But until now, it’s been an impossible resource to manage.

We don’t have enough data to know just how much groundwater is hanging out below any given house or farm. Because it’s unregulated by the state, anyone can pump as much water as they want—a point of contention between those who think people own the water underneath their property and those who believe groundwater is a communal resource. To make matters worse, groundwater hasn’t been replenished during these dry times, and there’s been a recent rush to drill more wells in the San Joaquin Valley.

But while we can’t make it rain on California, nor force the legislature to pass two bills currently being considered that would mandate local governments to regulate their groundwater, new technology is allowing us to better “see”  the water beneath the ground and could help us make smarter decisions about how best to use it.

A recently developed sensor-based device that measures groundwater is helping UC Berkeley researchers understand just how much of this resource we’ll have in the coming decades. Developed by Wisconsin-based startup Wellntel, the product attaches to the top of a well and uses sonar to measure water levels and a well’s pumping rate every 30 minutes, then sends the data to the computing cloud, allowing researchers to make use of it.

In the last few months, geography department professor Norman Miller and recent Ph.D. graduate Raj Singh have started incorporating data from the devices into the computer-based groundwater model they’ve been developing for the last four years. “One of the big problems I see is the availability of water due to land use stressors under climate change,” says Miller, a hydrometeorologist. “So one of the outstanding questions is how much (groundwater) is left on planet, who’s using it, and when. But there’s a lot of water that we can’t see.”

The current problem, the researchers say, is that while satellite data can show how much groundwater there is on a regional level—in the Central Valley, for instance—it can’t capture how much there is under a city, or at the farm level. There just isn’t enough data from U.S. wells to get a deep understanding of how groundwater flows. The predominant techniques used to measure well water levels—measuring tapes or pressure sensors—are labor-intensive and costly. The U.S. Geological Survey monitors less than 10 percent of its 20,000 wells, California’s Department of Water Resources monitors a few hundred.

But by integrating the Wellntel data into their current model, the Cal researchers believe they can provide a deeper understanding of how much groundwater we have now, and how much we’ll have in the future as climate change takes its toll.

“It’s like moving from a black-and-white to an HD television,” Singh says of the difference in resolution—which with the new data has advanced from gathering data at the 10-20 kilometer level down to a 100-meter level. At that resolution, he says it’s possible to discern the land’s topography and groundwater level differences from houses a few blocks apart.

With this knowledge, farmers and landowners could be better equipped to allocate their consumption, plan their growing seasons and save for dry times—not unlike the way we manage our bank accounts.

Wellntel is partnering with Miller and Singh on a pilot research project in Templeton, a town just outside Paso Robles on California’s Central Coast. The area has sprouted a number of vineyards and hobby farms in recent decades after its almond groves turned fallow.

“There’s been a huge increase in vineyard development in Paso Robles, and many residents saw dramatic declines in their water levels and had to dig new wells because the water table dropped,” says Wellntel co-founder Nick Hayes. “And some of the new wells have had to go so deep that they have to tap into mineral and sulfur-smelling water—it’s pretty severe and it feels dire to them, and their property values are tied to water in the area.” Some even have had to truck in their water, Hayes adds.

Every two weeks, Miller and Singh receive data (stripped of any identifiers) from 12 Wellntel sensors installed every half-mile throughout the 9-square mile pilot area.

By assimilating this data into their current groundwater model, the researchers say they’ll eventually be able to predict how groundwater levels will change from season to season over the next few years, as well as over the coming decades based on a range of greenhouse gas emissions scenarios up to 2050.

Miller says it’s not clear right now just when they’ll be able to make those predictions. But the Cal researchers have met several times and shared their model with Frances Chung, the chief of the modeling branch at the state’s Department of Water Resources, and they say the state is interested in making use of the new technology. Such an ability to collect information about groundwater levels could boost the state’s pro-regulation movement.

“If you limit water it has to be based on what you know, and right now it’s extremely difficult to control and monitor,” Singh says. “But as we get more information and it becomes more scientific—and more objective based on facts—it will be easier to regulate.”

The link between dying wildlife, slavery and terrorism

TakePart | July 24, 2014

Rhino Action Day 2010The decimation of the planet’s wildlife is extracting a high cost on humans as it drives child slavery, human trafficking, and terrorism, according to a special report published Thursday in the journal Science.

Take poaching. Beyond the horrific impact on vanishing species, the slaughter of rhinoceroses and elephants for their valuable horns and tusks has bankrolled terrorist attacks in Africa by the extremist group Boko Haram.

The severe depletion of fish stocks around the world, meanwhile, has prompted an increased demand for cheap labor in the form of child slavery. That’s because it takes more time, workers, and money to catch fish that are less abundant, according to Justin Brashares, an ecology professor at the University of California, Berkeley, and the lead author of the Science paper.

“Millions of dollars are being spent by the European Union and the United Nations in anti-wildlife trafficking efforts—China started doing this as well—but almost all of [the efforts] are enforcement based,” he said. “They overlook that more than a billion people rely on natural resources for their livelihoods and don’t have any alternatives.”

Brashares wrote in the report that diminished fish stocks can push foreign fishing boats to travel farther for their catch, which puts more pressure on local fish populations. Such competition for scarce resources can lead to violent incidents, such as when Somali pirates attack foreign fishing boats that enter their waters.

Local, national, and international laws that recognize communities’ fishing and hunting rights—also known as tenure rights—are needed to address the underlying poverty driving such illegal actions, Brashares said.

“Fiji is a popular example where local fishing communities were given tenure rights,” Brashares said. “It seems to have worked very well in regulating harvesting and sustainability and allowed communities to be more connected to economic markets. In Namibia, local communities have secured tenure rights to wildlife and have had really positive outcomes in sustainability.”

So what can you do?

Brashares believes the most effective action individuals can take is to use resources such as GoodGuide—which rates the environmental health and safety of consumer products—or the Monterey Bay Aquarium’s Seafood Watch recommendations to identify responsible purchases. Economic decisions have more impact than emails to members of Congress, he said.

“If you say, ‘I can’t find out if my fish comes from slave labor,’ then I say that’s a great role for our nonprofits,” Brashares said. “We can push the Monterey Bay Aquarium to tell us what fish is socially sustainable.”

New biopesticide offers hope for honey bees

TakePart | June 6, 2014

There’s finally some good news about the plight of the honeybees, which pollinate a third of our food but whose populations have been crashing over the past eight years.

Scientific studies have implicated a class of agricultural pesticides called neonicotinoids, or neonics, along with other factors such as poor nutrition. Now researchers in the United Kingdom have created a nontoxic biopesticide made from spider venom and a plant protein. The substance, called Hv1a/GNA, is experimental, and its effectiveness in killing agricultural pests remains unproved. But it’s one indication that biopesticides could one day serve as an alternative to bee-killing chemicals.

“Our findings suggest that Hv1a/GNA is unlikely to cause any detrimental effects on honeybees,” said Newcastle University professor Angharad Gatehouse about the biopesticide, which combines an Australian funnel-web spider’s venom and snowdrop lectin protein, which is found in potatoes, rice, and other plants.

In the study, published this week in Proceedings B, the Royal Society’s biology research journal, the scientists found that the survival of honeybees exposed to a variety of doses of the biopesticide for more than a week was only “slightly” affected. The biopesticide also had no measurable impact on their learning and memory. That’s important because bees memorize the route to a food source and communicate it to the hive.

Lead study author Erich Nakasu believes that because the honeybees’ learning and memory capacity did not change, the biopesticide does not interact with the insects’ calcium channels, which are linked to those characteristics.

Hv1a/GNA has to be ingested by the honeybees, such as when they eat pollen, to have any effect, and thus it cannot be absorbed via routine body contact with plants during pollination, he added.

Researchers said that it also did not affect the larvae, as the developing honeybees were able to break down the biopesticide in their guts.

In addition to U.S. agriculture—which is a big consumer of neonicotinoid pesticides, especially for genetically modified corn—the research has implications for Canada, another large pesticide user. Citing high risks for honeybees, the European Union last year imposed a two-year ban on the use of three types of neonicotinoids—clothianidin, imidacloprid, and thiamethoxam.

Yet despite Hv1a/GNA’s potential as an alternative, Gatehouse warns that a range of strategies must be used to keep bees alive.

“There isn’t going to be one silver bullet,” she said. “What we need is an integrated pest management strategy, and insect-specific pesticides will be just one part of that.”

Tapping the sun to put more food on Africa’s table

For farmers in Mozambique, every harvest is bittersweet. That’s because up to 40 percent of their crops can spoil, as there’s no way to keep them cool. It’s a common and costly problem in countries that lack reliable power grids—or have no access to electricity at all—and that can ill afford to throw away food.

Farmers can use diesel generators to refrigerate produce, but they’re expensive and cause pollution. What if they could tap carbon-free solar energy to power a device that chills newly harvested crops, thus extending their shelf life? Better yet, that device could be manufactured locally, creating jobs.

Rebound Technology of Boulder, Colo., is trying to do just that. Formed by two solar industry exiles, the start-up is developing a 3-D-printed heat exchanger and a membrane made from a Gore-Tex-like material that uses solar thermal heat to create refrigeration.

“If we can cool the products in the field, then that will be really beneficial. In Mozambique, crops are being harvested in 77 to 86 degrees Fahrenheit,” said Kevin Davis, Rebound’s cofounder and CEO. “By lowering the temp of that product you’re stunting some of the metabolic processes that lead to spoilage.”

Higher-quality produce could be sold for up to four times more than the price of fruits and vegetables that have not been chilled before being transported to market, Davis says. Because women are buying the food from farmers to sell at the markets in Mozambique, it would also help women small business owners, according to Koos Van Der Merwe, the co-owner of Mozambique Organicos, a farm that is partnering with Rebound to field-test the technology next year.

Here’s how it works: Salt is dissolved in warm water running through a 3-D-printed heat exchanger. The saltwater solution absorbs the heat from the warm water, which makes it colder. That dip in temperature chills another pool of water that the farmers dunk their produce into after harvesting. To ready the process for the next day, a membrane placed into the saltwater uses heat generated by a solar thermal panel to separate out the salt and water across the membrane.

As simple as it sounds, Rebound’s product—dubbed SunChill—has some way to go before it can be deployed to Mozambique farmers. With $1.4 million in funding from the U.S. Agency for International Development—via “Powering Agriculture,” a new program aimed at fostering clean-tech solutions to boost agricultural productivity in developing countries—Davis and cofounder Russell Muren will spend the better part of the next year designing and testing the SunChill prototype.

The pair will meet with smallholder farmers in Mozambique this month to gather information for the design process. They’re also working with German collaborators to finalize the membrane’s design.

One challenge the company is still working out, Davis says, is the best way to get SunChill into the hands of small farmers, given the system’s expected $6,000 price tag. Rebound thinks it’s feasible for larger operations such as Mozambique Organicos or agricultural co-ops to purchase the equipment for use by a large group of farmers.

Van Der Merwe, who is about to start a business working with small farmers, says SunChill can fill a void. “I’m quickly running out of capacity to accommodate all small-scale production,” he says. “Being [that we supply] mostly produce for the local markets, we’re hoping that the SunChill technology can provide the answer to this need.”

Underground carbon store is a greenhouse gas bomb

Although most of the attention given to greenhouse gas has focused on the air around and above us, another significant source of carbon could contribute to climate change and has been unaccounted for: soot and fossils buried in soil that formed up to 15,000 years ago.

That’s the conclusion of a new study by researchers at the University of Wisconsin–Madison, who dug as much as six and a half meters below the surface in Kansas, Nebraska, and other parts of the Great Plains to reach ancient soils filled with black carbon and plants that have not yet fully decomposed. These carbon stores could be released into the environment via erosion, road construction, mining, or deforestation.

“It was assumed that there was little carbon in deeper soil,” said Erika Marín-Spiotta, a professor at UW-Madison and a coauthor of the study, published earlier this week in the journal Nature Geoscience. Most soil studies don’t penetrate deeper than 30 centimeters, she said, leading scientists to dramatically underestimate underground carbon reserves.

Only recently have scientists become more concerned about deep soil carbon, Marín-Spiotta said. Her research team believes a situation similar to that which it has documented in the American Midwest may exist elsewhere, such as in China and France. Because such carbon reservoirs in buried soils can lurk in a range of environments—under dust accumulation, in floodplains, in valleys, at the foot of slopes of hills and mountains and under lava flows—they are likely to occur in many other parts of the world.

Just how much carbon are we talking about? While it’s hard to get a global estimate, Marín-Spiotta said as much as 5.95 trillion pounds of carbon could be lurking in the depths of the Great Plains area her team looked at. That’s assuming the ancient soil forms a continuous layer across the region; the researchers were only able to collect measurements from specific points and don’t really know what portion of the region contains the carbon-rich soil, so Marín-Spiotta acknowledges that’s a high estimate.

“The large source of uncertainty is where these buried soils are located, at what depth do they occur, and over what spatial extent,” she said.

How could this giant carbon bomb be released? In some areas, it has already been exposed to the atmosphere. But for the subterranean reserves, Marín-Spiotta believes a number of factors are at work, including how much carbon there really is, how much has persisted since it was buried, and what kind of carbon is down there.

Though Marín-Spiotta says the buried reserves carbon don’t pose an immediate risk to rising CO2 levels in the atmosphere, she notes that land managers need to take precautions, as the researchers found the ancient soils are more reactive than was previously understood. Key among these, she said, would be to “estimate whether there are any [high-carbon] soils at a particular location [and if so] prevent erosion and exposure that would accelerate…release of CO2 to the atmosphere.”

Ready to charge your EV when driving?

Despite the growing popularity of electric vehicles—U.S. sales almost doubled from 2012 to 2013—fewer than 100,000 Americans drove one home last year. One reason is that it takes longer to fill a battery with electrons than to put gasoline in a tank, and consumers don’t want to wait longer than they’re accustomed to. But what if cars could be charged while driving over a road that can wirelessly transmit grid electricity from cables underneath? Could such technology be the convenience drivers are looking for to make the switch to electric?

A new partnership between Volvo and the Swedish government is trying to chip away at both ends of a catch-22 scenario that’s among the obstacles the concept faces: Nobody wants to pay extra for a wireless-charging feature that can’t be used yet, and no one wants to invest in infrastructure for a fleet of cars that doesn’t exist. Along with the Swedish Transport Administration, the car manufacturer recently announced an effort to study the potential of building electric roads that can power EVs wirelessly, a process also known as inductive charging. If everything checks out, so to speak, the duo will construct a stretch of road up to one-third of a mile long as early as next year in Gothenburg, Sweden’s second-largest city.

“Electric roads are another important part of the puzzle in our aim of achieving transport solutions that will minimize the impact on the environment,” said Niklas Gustavsson, the Volvo Group’s executive vice president of corporate sustainability and public affairs.

The Swedes will not be the first to debut this type of cleantech infrastructure. Last year, the city of Gumi, South Korea, led the way by installing a 14-mile electric road that wirelessly charged electric buses equipped with an underside device. When the bus drove over cables embedded underneath the road surface, the device converted the cable’s magnetic fields to electricity, according to Discovery News.

A few years ago, a version of the South Korean buses ended up in Park City, Utah, and McAllen, Texas, via WAVE, an American company that licensed the technology. But unlike Utah, which now runs the buses (that get charged by parking over pads, not driving on a road) on its University of Utah campus, McAllen ran into financial problems, and the project stalled. Last November, the city decided to jump-start it once more. Other cities reportedly exploring these buses include Long Beach, Calif.; Monterey, Calif.; New York City; and Seattle.

How soon could wirelessly charged EV cars hit the market? With Toyota in the midst of testing three modified Prius models in Japan, it could be just a few years away.

Volvo has also been conducting experiments with wirelessly charging EV cars in Belgium with its C30 Electric model, according to Green Car Reports. If the car manufacturer’s electric road in Gothenburg becomes a reality, it will be built along a new bus line dubbed “ElectriCity,” and three of its plug-in hybrid buses currently running in the city will be modified to charge while in operation.

“Close cooperation between society and industry is needed for such a development to be possible,” said Gustavsson, “and we look forward to investigating the possibilities together with the city of Gothenburg.”

How innovative solar is trumping oil in Tanzania

TakePart | May 20, 2014

While nearly 20 percent of people worldwide lack access to electricity, the rate is even higher in the East African nation of Tanzania: 84 percent of the country is off the grid. In the country’s rural areas, access is even sparser.

Sounds like a sweet spot for solar, right? But the up-front costs for a solar panel, battery, and charger are out of reach for the average village resident, not to mention the additional costs of equipment maintenance and repair. Rent-to-own schemes, which require users to pay for their system over time, aren’t practical either, given today’s rapid advancements in technology. So kerosene lamps and diesel fuel generators have remained the default go-to for most.

What if rural Tanzanians could bypass the financial barriers and lease their solar systems instead? What if this enterprise could create local jobs by employing agents to sell electricity services door-to-door?

That’s the business model of Off.Grid:Electric, a start-up founded in 2012 by a trio of American social entrepreneurs.

“We’re the SolarCity of Africa,” said cofounder Erica Mackey. She was originally interested in finding a solution to last-mile rural health care delivery in Tanzania, but switched to energy services after locals told her the lack of access to electricity was the largest obstacle to rural development. “We realized that the biggest barrier to implementing solar on a wide scale was because customers had to assume a lot of risk. So we take on that risk and deliver energy services.”

Off.Grid:Electric customers get a solar panel and metered battery storage and have electrical accessories (such as a charger) installed in their home. They prepay for as much electricity as they want—24 hours of power costs the equivalent of 20 cents a day, or about $6 a month—about what the average Tanzanian household spends on a night’s worth of kerosene for a single lantern. Families might use as many as three lantern loads per night, depending on the circumstances, Mackey says. Solar power can provide 35 times more light—and charge phones. An app enables subscribers to re-up their accounts using their phones.

Affordable electricity provides families with more time for work, study, and leisure activities. And clean electricity offers big health and environmental benefits over kerosene and diesel. Apart from the carbon emissions associated with the fuels, Mackey said that operating a single kerosene lamp indoors for four hours is the equivalent of secondhand smoke from two packs of cigarettes.

By using the “Avon lady” sales model that deploys locals to sell Off.Grid:Electric’s services door-to-door—more than 300 agents are in the field—the company has created jobs that pay three to four times more than what individuals were earning before, Mackey says.

The company operates in three regions of Tanzania and has enrolled more than 70 percent of homes in some villages, according to Mackey. Thanks to a recent $7 million funding round from high-profile investors such as SolarCity, Vulcan Capital, and Omidyar Networks, Off.Grid:Electric plans to move into other parts of the country, anticipating it will have close to 1,000 agents on the ground by the end of the year. It hopes to expand to Uganda and Kenya.

“That’s one of the most exciting things we can do—to make an African rooftop investable for a Western investor,” Mackey said. “That alone puts resources behind a big problem.”

Will UC make history and pull the plug on fossil fuels?

CALIFORNIA Magazine | April 21, 2014

When 29-year-old UC Berkeley student Ophir Bruck spotted Sherry Lansing, the former CEO of Paramount Pictures, on her way to a University of California Regents meeting, he was holding on to a key that he hoped she wouldn’t refuse.

“We’re here to call on the UC Regents to take bold action on climate change,” Bruck told Lansing last May, as she walked past 58 chanting students chained to two homemade structures designed to represent oil drilling rigs. “Will you symbolically unlock us from a future of fossil fuel dependence and climate chaos?”

“I drive a Prius,” Lansing replied, without stopping.

But now the issue is coming to a head at the University of California system, as activists push hard for it to become the nation’s first large public research institution to jettison fossil fuel investments. Over the coming months, the UC Board of Regents—trustees of a $6.4 billion endowment, one of higher education’s greatest—will be forced to grapple with the question.

As climate change accelerates faster than ever before—and with the world’s top oil, gas and coal companies already controlling a tremendous amount of fossil fuels—college students all over the country are urgently pressuring universities to divest their holdings of these corporations. Thus far 10 U.S. colleges and universities have committed to divest, and the movement is active on 450 campuses nationwide. To date, over 60 more entities (mostly municipalities, churches and foundations) have heeded the call to divest, attributing their actions in part to a desire to leave a world that future generations will be able to inhabit.

But it has particular frisson at UC Berkeley, where on Monday student activists dressed in black kicked off Earth Week 2014 by lying down in Dwinelle Plaza to simulate a “human oil spill”—and to demand the UC system divest itself of fossil fuel companies. With historically successful divestment campaigns targeting then-apartheid South Africa, tobacco companies and Sudan, Cal students have been catalysts for turning financial calculations into moral ones.

“If we do not divest from fossil fuels, and continue business as usual, future UC students will not have livable futures—and it’s part of the Regents’ fiduciary duty to ensure that they do,” says 21-year-old UC Berkeley junior Victoria Fernandez, one of Fossil Free Cal’s campaign leaders.

Fernandez, an environmental studies major, has made her cause consistently visible to the Regents over the past year. She repeatedly turns up at their meetings to give public comments, was one of the 58 chained to the oil rig, and regularly tries to engage the throng of students rushing through Sproul Plaza to join divestment efforts.

She’s motivated by her father, the son of a braceros agricultural worker from Zacatecas, Mexico who labored on a date farm in Indio, Calif. “My dad never wanted to waste anything and recycled everything—those values were cemented in me growing up,” she said. When her father immigrated to the U.S. at the age of 5, the family lived in the one tiny shack sitting in the midst of a huge stand of palm trees.

Bruck, an environmental studies re-entry student who is poised to graduate next month, says that divesting presents transformational promise for society. “It’s more than about just reducing carbon emissions—it’s a justice issue,” he says. “It’s an opportunity to rethink outdated political, economic and social systems out of which the crisis was born.”

While UC has been listening to what Fernandez and Bruck are saying about the need to divest, it’s not fully convinced. UC Regent Bonnie Reiss—who served as a climate advisor to former California Gov. Arnold Schwarzenegger—and UC Chief Financial Officer Peter Taylor question the benefits of divestment from a portfolio tasked with bringing in returns to support faculty research and student scholarships, as well as whether divestment would actually weaken the industry at all.

“UC’s mission is not just to fight climate change—our primary mission is access and affordability to receive a great education,” Reiss says. “So it should be a really rare incident where you’re putting any restrictions on your investment criteria that are anything but maximizing your return on investment.”

Both Reiss and Taylor point to the UC’s decision to divest from tobacco stocks in 2001 as proof of such risk. Each year, the university system analyzes how the portfolio would have performed had it not divested. During the 2012-2013 fiscal year, the portfolio earned $44.9 million more without the tobacco stocks.

But when looking at its cumulative difference calculated between the portfolio and its hypothetical alter ego between 2001-2013, the portfolio lost $471.6 million. “Are tobacco companies any less vibrant since 2001?” Taylor asks. “I don’t think it’s appropriate for staff members make value judgments on whether we should invest in tobacco companies, if genetic engineering is good or bad, if fossil fuels are good or bad. Where do you draw the line? What’s the answer to that? I’d love to know.”

Back in 2011, a divestment campaign targeting a select group of coal companies failed to take off on campus. But a broader initiative gained momentum last spring, a few months after climate activist Bill McKibben spoke at Berkeley as part of a national tour to rally supporters around the campaign organized by his nonprofit organization 350.org. Its call: Institutions should divest from the top 200 oil, gas and coal companies.

Bruck was in the crowd that evening—one of just 15 to 20 students among a few hundred people, he observed, when McKibben asked all the students in the room to stand up.

“He called upon us, saying that you have the power to take action and to leverage your position as students and push your institutions to act on climate,” Bruck says. “The whole presentation—it gets you mad, it gets you scared. Not fearmongering-scared, but realistically concerned about everything you care about.”

350.org’s argument is based on research showing that if the top companies burned all of their reserves, it would raise the earth’s temperature beyond 2 degrees Celsius—the amount that governments agreed not to exceed collectively in the international climate agreement brokered at Copenhagen in 2009. Anything beyond this threshold, U.N. climate scientists predict, will create a world of heat waves, unprecedented sea-level rise and not enough food and water to support an increased population of nine billion people by 2050. Recently, the UN’s Intergovernmental Panel on Climate Change released a report concluding that greenhouse gas emissions need to be cut from 40 to 70 percent by midcentury in order to prevent a climate catastrophe.

And according to Carbon Tracker, the London-based think tank that conducted the top 200 companies research, these corporations have five times more carbon to burn than the amount that would keep the earth below the two-degree limit.

After McKibben addressed the students, Bruck recalls feeling a responsibility to take action, though he had never really committed himself to organizing on an issue before. “Things in my life culminated where I was ready to engage myself at this moment—and climate change was not one of those issues until I came out of that talk,” he says.

Students at Cal and other UCs adopted 350.org’s call for action. They began asking the Regents to divest $11.2 billion  (a $6.4 billion general endowment pool and an additional $4.8 billion sitting in campus endowments) from these top 200 companies within five years of making the commitment. Their kickoff rally was at the Regents’ Sacramento meeting last May, when they chained themselves to the symbolic oil rig, chanted calls for divestment and gave a 15-minute speech to the regents via 15 students speaking one minute at a time, so as not to violate the one-minute public comment limit.

In January, after Fernandez and Bruck discussed the issue with a group of Regents over lunch, the Regents agreed to set up a task force comprised of students, Regents and faculty that would examine the issue and bring its findings to the Regents’ Committee on Investments. The task force would then make a recommendation to the committee, which would in turn make their recommendation to the full body of Regents. Finally, Regents would vote on whether to divest its endowment.

“It’s the same process that the Regents went through before voting to divest from Sudan in 2006,” says Bruck.

But unlike the Sudan divestment—one that involved just nine companies—oil, gas and coal companies are a trickier and more pervasive proposition. Taylor estimates that of the university system’s $6.4 billion general endowment holdings, “just north” of $100 million are invested in fossil fuel stocks.

“It’s not impossible, but it’s an uphill battle for the Regents to approve this,” says Reiss. “We need to analyze the true costs and benefits.”

She contends that UC initiatives such as its green building requirements, and UC President Janet Napolitano’s goal to get the nine-campus system carbon neutral by 2025, are more effective ways to fight climate change. Green construction, she says, not only reduces carbon emissions, but also creates markets for sustainable building materials and clean technology.

Students such as Fernandez and Bruck admit that if UC decides to divest from fossil fuels, it would be a symbolic gesture and probably not make an impact on the huge corporations’ bottom lines. But they insist there is more to gain by changing public opinion.

“At the end of the day, we’re trying to stigmatize the fossil fuel industry and take away their social license to operate,” Fernandez says. “The harmful things fossil fuel companies do to communities are not seen by the economy and the world as a whole. They hurt them economically and health-wise. Look at Chevron in Richmond.”

Creating that social stigma has worked before. Although UC Regents and Berkeley chancellors initially resisted thousands of anti-apartheid activists pushing for divestment from South Africa, the university system did so in 1986 after 18 months of demonstrations and physical confrontations between protestors and campus police, anti-apartheid activist and Berkeley alumni Steve Masover has recalled. In 1990, Nelson Mandela credited the Berkeley movement with playing a significant role in the downfall of apartheid.

Bruck is bracing for the long haul. After graduation, he says, he can see himself continuing to do climate change organizing full-time.

CEO Andrew Behar of As You Sow, an Oakland-based shareholder activist group, sees another compelling financial reason to divest. He’s among a growing group of investors warning of the risk of investing in fossil fuel companies because of the “carbon bubble”—the idea that the value of fossil fuel stock is overpriced. The theory goes like this: If governments pass climate regulations or carbon taxes to prevent the earth’s temperature from rising beyond 2 degrees Celsius, fossil fuel companies will be forced to leave most of their reserves in the ground. To keep that temperature threshold, according to a 2013 study by Carbon Tracker, only 20 to 40 percent of those reserves could be burned.

Behar estimates the value of the carbon bubble, or the industry’s “stranded assets,” as they’ve also been dubbed, to be $20 trillion. He says that in the last year, the bubble has already started to burst as coal has been dumped in favor of natural gas and renewable energy sources.

“Nine coal companies went bankrupt last year. If you bought coal two years ago, you lost 58 percent of their portfolio’s original value,” he says. “It’s moving more rapidly even than anyone thought possible.”

In March, in a response to pressure from activists, ExxonMobil released a report to shareholders that concluded “we are confident that none of our hydrocarbon reserves are now or will become ‘stranded.’ We believe producing these assets is essential to meeting growing energy demand worldwide, and in preventing consumers—especially those in the least developed and most vulnerable economies—from themselves becoming stranded in the global pursuit of higher living standards and greater economic opportunity.”

Out of the 10 colleges that have chosen to divest in fossil fuels, most are small and private. The largest was Pitzer College, which announced on April 12 (via trustee Robert Redford) its decision to divest its $130 million.

There’s a reason why no large public institution has stepped into the ring thus far. “Many universities remain unwilling to risk their endowments and need, frankly, more certainty,” says Taylor, citing an op-ed by the University of Michigan’s Chief Investment Officer Erik Lundberg arguing that divestment was impractical.

And with a $32.7 billion endowment—the largest treasure chest among all U.S. colleges and universities—Harvard President Drew Faust emphatically dismissed divestment, citing concerns that the university would inappropriately appear to be a “political” actor, as well as risk future returns. (Recently, the university signed on to UN-backed principles for “responsible investment.” That is a non-binding framework, which critics see as an empty gesture).

But those who have studied the impacts of fossil fuel divestment—as well as at least one college that divested—refute the idea that it will inevitably lead to financial losses.

“Our analysis found that if you are doing market cap weighted indexing, there is very little cost to divestment from a risk standpoint,” said Liz Michaels of Aperio Group, a Sausalito, Calif.-based investment management firm specializing in value-based investing. The company doesn’t maintain a position on fossil fuel divestment.

Aperio—which subscribes to the philosophy that investors can only match the market, not beat it—used Barra proprietary software to remove a portfolio’s holdings in the fossil fuel sector, then asked it to reinvest and reweight them to match market performance as much as possible.

“We’ve done much better after divestment,” said Stephen Mulkey, the president of Unity College in Maine, which divested in November of 2012. “We’ve achieved significant gains because we are paying closer—almost daily—attention”—a constant watch of its portfolio funds to ensure that fossil fuel holdings stay below 1 percent of the college’s endowment. The college also invests all proceeds from the fossil fuel holdings into an internal fund that provides financing for energy efficiency, renewable energy, or other sustainability projects, with the money saved then invested back into the fund.

The UC Regents’ Committee on Investments Task Force has yet to be convened. At last month’s Regents meeting, Fernandez and Bruck dutifully waited their turn to speak at the public comment session and remind the assembled group of the task force’s importance. Still, the students say that a vote on divestment is possible within the year; Taylor says a Regents discussion by November is realistic.

Many divestment backers simply advocate switching from fossil fuel holdings to cleantech and green bond holdings. But Berkeley energy professor and divestment advocate Daniel Kammen, a member of the Intergovernmental Panel on Climate Change, says it’s also important to draw on the expertise of the oil, gas and coal companies, spurring them to help create an economy that does not rely on fossil fuels.

“In the transition to renewable energy, we need to move them from extractive companies to knowledge-based companies,” he says. “There are more people that are really well versed in technology and economic policies in the big energy companies than anywhere else. So it would be crazy not to forge partnerships with them and build on their resources.”

There’s no price tag on a clear mind

At any given moment during the workweek, there’s a high possibility that employees at Silicon Valley tech companies are trying to disconnect from the very same products they have developed. Whether it’s via deep breathing, meditation or a quiet moment to reflect, companies like Google, Twitter and Medium encourage the use of mindfulness techniques as a way to trade digital clutter and stress for greater clarity and purpose.

But away from the spotlight, one of the sector’s oldest companies is quietly making plans to expand its program to a greater level than ever before. After two years of running an under-the-radar program at two locations in California and Oregon – initiated by a manager in its engineering department, no less – Intel is moving to make a nine-week mindfulness program available to its workforce of over 100,000 employees in 63 countries across the globe.

“There’s going to be a quantum leap,” said Lindsay Van Driel, the Hillsboro, Oregon-based manager who co-founded Awake@Intel with Portland leadership consultant Anakha Coman.

Using a train-the-trainer model, the program will be rolled out over the next six months to its first office locations. An employee is currently being trained in India, and others in China, Chile, Costa Rica and Ireland have expressed interest. Van Driel is adamant about making sure that Awake@Intel grows slowly so that the course is implemented in a way that stays true to its original intention.

“The right teachers [who will all be employees] will have to emerge as leaders before we can offer it there,” said Van Driel, who is also a certified meditation and yoga instructor. “It’s not something that anyone can teach. It has to be lived and embodied.” All sessions will be held with teachers and students in the same room.

Though Van Driel did consult with Chade-Meng Tan, the Google engineer who co-wrote the company’s Search Inside Yourself course on mindfulness and emotional intelligence with meditation teacher Mirabai Bush and San Francisco Zen Center priest Norman Fischer, she and Coman created a program that met the needs of a company mainly comprised of scientists and engineers, and one that cultivated the Intel values of innovation, candor, possibility thinking, risk taking and moving quickly and decisively. The curriculum was developed in three months.

Before the first weekly session, each participant identifies what he or she is most interested in improving. During the first month, the class learns to quiet their minds. They set intentions and explore the components of emotional intelligence. For the last part of the course, participants are exposed to mindful listening, delve into Brené Brown’s ideas on the influence that vulnerability has on innovation, then discuss Otto Scharmer’s concept of collective mindfulness. Each week, participants share their experiences and insight utilizing what they’ve learned over the course of the past week – for example, talking about how they moved from compulsion to choice.

“People get more authentically related to each other – beyond competency levels and their roles. So real ideas are heard and received, and people are much more generative together. The corporate mask that people put on when they walk through the door comes down,” Coman said.

Evaluation results have been notable among the 1,500 employees who have participated in 19 sessions to date. On average, participants responding to pre- and post- self-evaluation questionnaires report a two-point decrease (on a 10-point scale) in experiencing stress and feeling overwhelmed, a three-point increase in overall happiness and wellbeing, and a two-point increase in having new ideas and insights, mental clarity, creativity, the ability to focus, the quality of relationships at work and the level of engagement in meetings, projects and collaboration efforts.

Since the program is voluntary, it seems that employees aspiring to be mindful would surely be derailed by colleagues. But there’s still value, according to Coman. If one person can maintain presence in a conflict it won’t escalate, and it can help others to stay calm, she said.

How did a top tech company make the decision to invest in such a large program without a clear numerical return on investment?

Van Driel said that she focused on presenting scientific studies showing the health benefits of meditation, as well as the effect of the program on workers’ ability to relate better to each other and improve team performance. The company has not determined the amount of money it will put into the program at this time.

“If we show people pages and pages of our feedback, there’s nothing that anyone can say that takes away the validity of that experience,” she said. “If I have an engineer that says ‘I can solve a technical problem in two less weeks [after applying what was learned during the class]’, you can monetize it anywhere.”

Los Angeles subway generates wind energy

TakePart | April 4, 2014

Here’s a next-gen idea that’ll blow you away: Using a specialized turbine during a 10-day period in August and September 2013, the Los Angeles Metro rail system was able to capture the wind power coming from passing subway cars—and turn it into renewable energy.

The 10-foot-wide wind turbine—custom-built for the project, which was initiated by Metro’s Environmental Compliance unit—generated an average of 77.7 kwH per day, an amount that could produce 28,000 kwH if projected over an entire year. That’s enough to power 12 homes in California during the same time period, or prevent the annual release of more than 17 tons of CO2 emissions from natural gas (and more than 30 tons of CO2 emissions generated from coal), according to Metro estimates.

“To our knowledge, Metro is the first transit agency to have implemented an actual test and have real data to report,” said Metro spokesperson Anna Chen. University students in India got permission to install a turbine in Delhi’s subway system last year, and a team of Korean designers floated the idea in 2010, but no results have been publicly released to date.

The turbine—known as MACE (multi-blade mass airflow collection equipment)—was designed by WWT Tunnel, a Pasadena, Calif.–based company that develops technology aimed at generating energy from previously unused sources.

It took a few months to design the equipment and several days for Metro to install the MACE unit, Chen said. Because Metro trains run for up to 20 hours a day and the subway system often undergoes repairs in the lull between operations, there was only a three- to four-hour window each day to install the unit without interrupting subway service.

The MACE turbine was placed on the base of a tunnel wall on Metro’s Red Line between the North Hollywood and Universal City stations and was removed after the pilot project was complete. The agency chose to install it at a middle section of the tunnel, where trains are estimated to run up to 70 miles per hour.

“It’s the best place to get the maximum amount of wind because as the train leaves the station, the wind pushes out before it, and then the train creates the drag,” Chen said.

MACE’s blades start spinning a minute before the train passes by and stop two minutes after the train passes. During the pilot, the unit made more than 1,070 revolutions per minute.

To make sure that the blades could safely operate once underground, Metro and WWT Tunnel conducted aboveground testing in which the turbine was run through a series of wind simulations.

“They wanted to make sure that nothing broke off if the blades spun at maximum speeds,” Chen said.

Metro anticipates that it can store any excess wind energy produced by the turbines for use during times of peak demand. Because the trains run on a regular schedule, the underground wind energy can be a more reliable source of renewables than solar or aboveground wind.

But Metro is not ready to regularly start spinning the blades yet. Using the data collected during the pilot, it will release a report later in the year that will analyze the feasibility of the idea, as well as the effectiveness of MACE turbines.

“We’ll be making recommendations on how we can implement this throughout the system as a whole,” Chen said.
