How animal agriculture can help meet the Paris Climate Agreement goals

corn fieldThe Paris Climate Agreement included a special emphasis on food security and the threats it faces from extreme weather events. Despite only brief mentions of agriculture in the preamble to the agreement itself, a recent study from the University of Vermont reveals that global emissions reduction targets absolutely cannot be met without significant contributions from the agricultural sector.

According to this new research in Global Change Biology, agriculture needs to reduce emissions by one gigaton per year in 2030, yet current mitigation strategies can only meet 40 percent of this target, at most, and may deliver as little as 21 percent of what is needed.

The authors argue that agriculture needs to play its part, and I couldn’t agree more. We are dependent on agriculture not only to keep us fed, but also to lead the way in addressing climate change threats. Agriculture represents approximately 9 percent of total emissions in the U.S., and between 10 to 29 percent of emissions globally, though this figure is projected to increase.

Despite the fact that 119 nations included agricultural mitigation as an in-country strategy for meeting the Paris Agreement reduction targets, no country has yet reported on how to accomplish these pledges.

Ultimately, the responsibility to implement tangible on-farm changes that reduce emissions falls on billions of farmers, but there is an even greater responsibility for animal agriculture companies. Here’s why – and what these companies can do to help tackle the climate challenge. Read More »

A panel of experts forms the foundation of NutrientStar, the newly independent, science-based program that reviews the performance of commercially available nutrient management tools. This panel reviews all tools based on established scientific criteria and their ability to improve fertilizer efficiency in the field. The panel is a “who’s who” of fertilizer efficiency experts from across the country – from academia, government agencies, and the private sector.

And now, this eight-member panel can add to its ranks a new member: Eric Davidson, professor and director of the Appalachian Laboratory at the University of Maryland Center for Environmental Science.

Davidson, an ecologist, researches biogeochemical processes including the exchange of plant nutrients from the land to streams and groundwater, and the exchange of greenhouse gases between the soil and the atmosphere.

I asked him about his current research, his nitrogen expertise, and why he believes the NutrientStar model can be replicated at scale to improve water quality in places like the Chesapeake Bay.

A version of this piece previously ran as an op-ed in the Houston Chronicle.

A few years ago, I was invited by Texas farmer David Cleavinger to visit his family’s farm near Amarillo. This was during a period of time when my organization, Environmental Defense Fund, was deeply involved in conservation efforts for the lesser prairie-chicken, a colorful bird whose habitat is in decline throughout its five-state range, which includes the panhandle of Texas.

David picked me up at the airport and asked if we could make a quick stop on the way to his farm. That stop turned out to be at local radio station KGNC, where David had arranged for me to go on air and talk about wildlife conservation with a particular focus on the local implications for efforts to revive the lesser prairie-chicken.

I agreed to join the show with some trepidation, but it quickly subsided as we got into a lively discussion with the host, James Hunt, and several listeners. Toward the end of my appearance, a caller asked a surprising and provocative question – What if God wants the prairie-chicken to go extinct? Read More »

Controlled drainage is the new black

Dr. Mohamed Youssef demonstrates the benefits of controlled drainage.

Dr. Mohamed Youssef demonstrates the benefits of controlled drainage.

NC State University’s agriculture water management expert Mohamed Youssef, Ph.D, believes the time is ripe for controlled drainage to make a comeback.

Controlled drainage is one of the most effective ways to minimize nitrogen loss from croplands. It’s a management practice involving the use of a control structure installed at the outlet of a drainage ditch or subsurface drain to regulate drainage water outflow according to plant needs and field operations.

“A controlled drainage system can remove between 40 and 60 percent of the nitrogen present in runoff, if used at a large scale. These systems hold huge potential to reduce pollution from very large flows of water runoff,” Youssef explained during my recent visit to NC State’s demonstration farms in eastern North Carolina.

Despite the promise, adoption rates for this practice remain very low, in part because of functionality problems with the first controlled drainage structures. But thanks to new advances in the technology that I recently viewed in the field, adoption rates are rising.

Like any filter practice, controlled drainage is just one tool that can help solve regional water quality problems. It’s not a silver bullet, especially with some geographic limitations since they can be used only on low-sloping fields. While there is no perfect solution to stop farm runoff, after seeing drainage systems first-hand, I too believe we’re nearing a tipping point for widespread adoption of controlled drainage in agriculture – and big environmental benefits. Here’s the story. Read More »

A monarch caterpillar eats antelope horn milkweed growing at Shield Ranch.

A few weeks ago, I visited Shield Ranch, a 6,000-acre property devoted to responsible cattle management and wildlife conservation. I made the visit to the ranch – less than 20 miles west of my home in Austin – to test a new tool being designed to more accurately assess habitat for the monarch butterfly.

Standing in a field of wildflowers with a team of scientists, we used the monarch butterfly habitat quantification tool to measure vegetation and determine what monarch habitat was available on the property. We’ve used similar habitat quantification tools for other at-risk wildlife like the lesser prairie-chicken and greater sage-grouse, but this was the first time we tested a tool for monarch butterfly habitat.

Why investments in agricultural carbon markets make good business sense

Farmers shaking handsOver the past decade, private investment in conservation has more than doubled, with sustainable forestry and agriculture investments as the main drivers of growth. This unprecedented expansion in “impact investing” or “conservation finance” has occurred as investors seek good returns that can also benefit the environment.  According to Credit Suisse, sustainable agriculture is particularly appealing to investors as it offers a wider array of risk mitigation approaches than sectors such as energy and transportation.

Yet despite this boom, there has been very little investment from private capital in emerging ecosystems markets, especially in the agricultural sector.

We’ve blogged before about the benefits growers – and the environment – realize from participating in agricultural carbon markets or habitat exchanges. But here’s why the private sector, food companies and retailers should invest in agricultural carbon markets. Read More »

New guidebook explains how and why to build a farmer network

Farmers educating about cornAmidst all the new tools and technologies being developed to make agriculture more sustainable, there is one tried and true method for testing on-site conservation practices that doesn’t get much attention: farmer networks.

Farmer networks consist of growers within a region working directly with advisors, agronomists and/or scientists to conduct on-farm trials. These trials can test the economic and environmental impacts of changes in crop management, adoption of soil health practices, or use of precision agriculture tools.  The data is then aggregated and analyzed to determine best practices for specific farm conditions and to inform future management decisions.

Originally established by the Iowa Soybean Association, the innovative farmer network model has since taken off, with Environmental Defense Fund and others establishing additional networks across the country. As University of Connecticut soil fertility expert Thomas Morris explains, participation in farmer networks has led to greater efficiency on hundreds of thousands of acres across the U.S – benefitting both the planet and yield. The potential for replication is limitless.

That’s why EDF created a how-to guide for other organizations, companies, and universities interested in creating a farmer network. The new Farmer Network Design Manual provides a roadmap to support sustainable agriculture practices, increase farm profits, and build resiliency. Read More »

Despite drought, California agriculture is doing well. But there are hidden costs.

Water scarcity has affected California vineyards

According to a new World Bank report, regions around the world could gain or lose up to 6 percent of their GDP by 2050 depending on how they manage for climate-driven water scarcity.

I was curious about how the report’s findings might apply to California, where I live.

Here in the Golden State, water scarcity is a familiar threat. And while the World Bank found that climate-water costs to North American GDP should be minimal, many Californians have suffered acutely from sustained drought.

In some cases, however, it isn’t entirely clear what the impacts of water scarcity have been. Read More »

From Southwestern India to Iowa: Why farming is at the heart of sustainability

Hiking in India

Studying in the Western Ghats region of India.

When I was younger, I fantasized about becoming a Jane Goodall for the millennial generation. I imagined living in the wilderness to study animals’ behavior and help conserve land. During college, I briefly lived out my dream when I spent a summer in the biodiversity-rich Western Ghats region of India, living and working on a private wildlife sanctuary where I studied the local flora.

The sanctuary was an island of preserved land, surrounded by vast farms that dominated the region’s landscape. While there, I had an epiphany – one that brought me back to my own family’s agricultural history on a farm in Iowa.

I realized that if we don’t work with farmers to conserve wild places, we will never be able to create truly sustainable environments for animals and humans. If I really wanted to make an impact on the Ghats region and its biodiversity, I’d need to move beyond a private sanctuary and back toward my family’s farming roots.

India showed me first-hand the need to partner with farmers. Spending summers on my family’s farm in Iowa and steering the tractor with my grandfather taught me to appreciate the integral role farmers play in maintaining balance in the ecosystem – and that farming is incredibly hard work. Both of these experiences still influence my agricultural career, which is focused on deploying the SUSTAIN™ platform, developed by United Suppliers, Inc. in coordination with EDF, to assist growers in improving fertilizer efficiency and soil health.

What do western ranchers and a southern environmentalist have in common?

I trace my love of the outdoors to two memories: the first, sitting with my grandmother watching the goldfinches, chickadees and wrens that visited her feeder, and the second, camping in Pisgah National Forest with my parents and sister.

Days spent with my grandmother in our small South Carolina town left an indelible mark on my life. She taught me a conservation ethic that led me to Environmental Defense Fund (EDF). Camping taught me a love of the land and a respect for those that manage it.

As director of habitat markets, I’m focused on building conservation solutions for wildlife like the greater sage-grouse, a bird that lives more than 2,000 miles from my home in a landscape unlike any of the forests or farms I grew up exploring.

The sage-grouse is an indicator species of a vast declining ecosystem spanning more than 150 million acres across 11 states. The grouse relies on the cover of sagebrush – one of the most iconic symbols of the western landscape.

Because EDF puts a premium on policy, science and collaboration with diverse stakeholders, we’ve been working with landowners, industry, and state and federal agencies to create a habitat exchange program to better ensure the bird’s survival. Common values make this collaboration possible. Read More »
