You may not know the name Dr. Changsheng Li, who passed away last week after a courageous battle with cancer, but his legacy will live on for generations.

A professor at the University of New Hampshire (UNH), Dr. Changsheng developed and refined a model that has been used in more than 20 countries to calculate methane and nitrous oxide emissions from crop production.

A UNH faculty award from 2009 noted that “it is rare to meet a person who fairly radiates humility and compassion. Changsheng Li of the Institute for the Study of Earth, Oceans, and Space is just such an individual.” He will be sorely missed by his friends at Environmental Defense Fund – and across the entire agricultural world.

His work took on new meaning and unprecedented momentum over the past few months with several big developments in the field of agricultural carbon markets – successes that would not have been possible without his pioneering work. Read More »

Fertilizer runoff is just one piece of the dead zone puzzle

By Eileen McLellan / Bio / Published: October 21, 2015

It’s true that fertilizer runoff, sewage, and other pollutants from the Corn Belt have significantly boosted dead zones in the Gulf of Mexico. That’s because up to half of the fertilizer applied isn’t absorbed by crops, and in order to grow more food we’re using 20 times more fertilizer in the Corn Belt today than in the 1950s.

But even if we optimize fertilizer use on all cropland in the Upper Mississippi and Ohio River Basins, nutrients will still be lost to rivers and streams and carried into the Gulf of Mexico. Some of this loss is inevitable given factors like unpredictable weather, but my colleagues and I set out to quantify other reasons for why the Corn Belt exports so much nitrogen.

We discovered that an increase in fertilizer inputs is only one part of the problem. Three other distinct but interconnected factors also contribute to water pollution and the Gulf dead zone: the loss of perennial cover, the construction of artificial drainage systems, and the loss of wetlands.

Today, a diverse group of more than 400 businesses, associations, government agencies, science organizations, academic institutions and non-profit organizations released the first-ever report card evaluating the condition of one of our nation’s most storied and central waterways. This effort, known as America’s Watershed Initiative, was undertaken to provide information on the challenges facing the waters and lands that make up the 31-state Mississippi River Watershed and the 250 rivers that flow into it.

The overall mark was less than stellar, a D+. However, the process of grading has yielded a pathway to improvement.

Why the poor rating? The watershed continues to experience increased pressure from the demands of urbanization, agriculture, transportation and land development.

Fortunately, moving from a “D+” to an “A” grade is achievable – with new levels of understanding and collaboration. That’s why the Environmental Defense Fund and the National Corn Growers Association have a real desire to work together on this and similar initiatives. Read More »

Walnut grower Craig McNamara on water banking, hedgerows, and the birds and the bees

By Eric Holst / Bio / Twitter profile / Published: September 24, 2015

Craig McNamara on his farm in Winters, California.

Craig McNamara embodies agricultural leadership in California. He has farmed a 450-acre organic walnut orchard in Winters, California for the past 35 years. He’s been an innovator in implementing conservation practices on his land that both enhance wildlife and benefit his farming operation. He’s also the president of the California State Board of Food and Agriculture, and an influential sustainable agriculture educator.

I’ve known Craig for about 10 years and have had the honor of serving with him on the State Board for the last two. I spoke with him about how he integrates farming with ecology and his plan for dealing with potential El Niño rains. Read More »

Ranchers and conservationists step up to avert listing of sage-grouse

By Eric Holst / Bio / Twitter profile / Published: September 22, 2015

Stakeholders conduct field tests for the Colorado Habitat Exchange on a ranch in Colorado.

The decision whether or not to list the greater sage-grouse under the Endangered Species Act was one of the biggest listing decisions of our time.

Thanks to unprecedented public-private partnerships among ranchers, energy developers, conservationists and states, we now have the groundwork to guide future management of our nation’s wildlife and working landscapes.

The “not warranted” decision sends a strong signal that investments in conservation are making a difference, providing the catalyst for a new approaches and a different kind of politics.

Saturday marked a new chapter in a years-long rabbit’s tale.

Of course I’m talking about the New England cottontail, which, until this week, was a candidate for listing under the Endangered Species Act.

Thanks to the work of private landowners, conservation groups, tribes, and state and government agencies, the U.S. Fish and Wildlife Service has decided to remove this critter from the candidate list and declare that it’s well on the path to recovery.

A team effort

The growth of the New England cottontail population was a team effort, with important contributions from state wildlife departments, the U.S. Fish and Wildlife Service, U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) and conservation organizations.

But the most important contribution came from farmers and forestland owners who committed to managing the specialized habitat of the New England cottontail. Read More »

Why wastewater treatment plants are investing in farmers

The Des Moines Water Works lawsuit represents one of the most contentious challenges in modern-day agriculture: who should pay for protecting water quality from excessive nutrient loads?

Excess nutrients in streams and watersheds can cause algae blooms as well as air and water pollution. Whether due to excess fertilizer runoff from agriculture, urban sewage, stormwater runoff, or air depositions of nitrogen, wastewater treatment facilities often bear the primary responsibility of nutrient removal in many watersheds. Under the Clean Water Act, these facilities are charged with cleaning water to a certain standard, which can be increasingly hard to meet – and to pay for – when excess nutrients are present.

But there are some interesting solutions in the works.

I asked Pat Sinicropi, Senior Director of Legislative Affairs at the National Association of Clean Water Agencies (NACWA), to tell me about the collaborative approach her organization is taking to solve the problem – by working with farmers. Read More »

How cover crops can help growers beat droughts and floods

By Maggie Monast / Bio / Twitter profile / Published: July 22, 2015

Cover crops can include grasses like cereal rye.

Corn is trying to fight this summer’s extreme weather, and unfortunately, the weather is winning.

There are serious floods in the Midwest, devastating droughts in California, and brutal heat waves along the eastern seaboard. Ohio for example had a record June rainfall of 11 inches, which stunted corn roots and prevented many growers from planting any corn crops. In Northwest Ohio alone, 100,000 acres were left unplanted. At the same time, places in my home state of North Carolina experienced a June heat wave during the critical corn pollination period, significantly damaging corn yields.

These extreme weather events leave many farmers searching for ways to make the best of a challenging growing season. Although June’s weather was the opposite in Ohio and North Carolina, cover crops offer a proven solution to deal with both conditions. Read More »

Note to Congress: Pitting fish against farms won’t solve California’s drought

By Ann Hayden / Bio / Published: July 15, 2015

(Updated July 16, 2015)

A bill to supposedly address California’s devastating drought, authored by Rep. David Valadao, cleared the House of Representatives today.

Unfortunately, this proposal – dubiously named the Western Water and American Food Security Act of 2015 – is yet another attempt to move more water through California’s vast Central Valley Project at a time when we can least afford it and at the expense of many water users.

Among other problems, the bill would permanently undermine science-based protections and regulatory assurances for at-risk species and ecosystems that are essential in providing reliable food, safe drinking water, and jobs to millions of Americans.

The proposed tradeoffs here are nothing new. Similar bills – H.R. 3964 and 5781 in 2014, both opposed by the White House and the State of California – also pitted fish against farms.

It’s time we move away from finger pointing and start finding collaborative solutions to the drought that increase the resiliency of our freshwater ecosystems while supporting agricultural communities in California’s Central Valley. Read More »

What a visit with a California citrus grower taught me about agricultural sustainability

By Sara Kroopf / Bio / Twitter profile / Published: July 6, 2015

EDF’s Sara Kroopf smells the soil at a citrus nursery in Arvin, California.

Putting yourself in the boots of a California farmer will give you a whole new perspective.

That’s why I recently spent a few days alongside Matt Fisher, a citrus grower in Kern County, California – to better understand growers’ challenges and concerns, and to rethink how environmental groups and farmers can achieve shared goals.

The experience was part of a farm exchange program offered through the California Agricultural Leadership Foundation, which facilitates learning opportunities on California farms.

With a record-breaking drought in California, tensions between environmentalists and farmers run high, and finger pointing is everywhere. But that isn’t getting us anywhere. The time I spent on Matt’s farm gave me new inspiration to break down barriers, put aside stereotypes, and work together. Read More »
