Congress Could Help Farmers, Prevent Pollution, and Reduce Flood and Drought Damage. Will They?

, senior analyst, Food and Environment

The news lately has been full of Congressional battles—healthcare, the debt ceiling, and now tax “reform” (ahem)—and it’s starting to seem like Congress is only interested in blowing things up. But a huge legislative effort is gaining steam on Capitol Hill, one that is likely to have general bipartisan support, though you probably haven’t heard nearly as much about it. I’m talking about the next five-year Farm Bill—which really should be called the Food and Farm Bill, as it shapes that sprawling economic sector worth more than 5 percent of US GDP, and which Congress must reauthorize by September 30, 2018.

In this first of a series of posts on the 2018 Farm Bill, I look at how this legislation could do more to help farmers conserve their soil, deliver clean water, and even reduce the devastating impacts of floods and droughts, all of which would save taxpayers’ money. Read more >

Floods, Droughts, and Soil: The Movie (or, Why I Destroyed a Small City for Page Views)

, Kendall Science Fellow

Our new report, Turning Soils into Sponges: How Farmers Can Fight Floods and Droughts, is a serious scientific analysis that documents how soil-covering farm practices can help farmers and communities better withstand rainfall variability. It took me the better part of two years to complete. But—lucky you!—we also made a quirky little movie about it that you can watch in less than three minutes. Read more >

This plant’s roots penetrate soil deeply, reducing compaction, and increasing water infiltration, making it an excellent cover crop to improve soil structure. Image: USDA-SARE/Edwin Remsberg.

How Healthier Soils Help Farms and Communities Downstream Deal with Floods and Droughts

, Kendall Science Fellow

A scan of recent news reveals the wide-ranging impacts of too much or too little rain: intensifying drought in the Great Plains; the largest dead zone in the Gulf of Mexico ever recorded, driven in large part by a wet spring that flooded parts of the Midwestern Corn Belt; and historic summertime rain in the mid-Atlantic. Climate change promises to bring more of this rainfall variability, with devastating effects on farmers and communities. But a new report we released today contains good news: healthier soil on farms can help combat the impact of floods and droughts.

Cover Crop Challenges: A Reminder That In Agriculture, Even Small Changes Can Be Hard

, Kendall Science Fellow

Why don’t more farmers plant cover crops? This is a question I am asked all the time when I talk about my research on the topic. Cover crops are not new—their historic use in agriculture includes many ancient civilizations and even our Founding Fathers. Cover crops simply mean growing a plant to “cover” and protect the soil when it would otherwise be bare. Live plant roots can reduce erosion and water pollution, and lead to more productive soil with time. Read more >

Soils to Reverse Climate Change: “Carbon Farming” and the Untapped Potential in Ecological Approaches

, Kendall Science Fellow

Are there agricultural practices that might offer more potential than the ones commonly discussed in the “carbon farming” conversation? In a companion post, I wrote about what the science tells us about cover cropping and reduced tillage, two practices getting a lot of attention in what I’ve called the “carbon farming” rage.
