As a young geologist, it took me a while to appreciate the importance of soil and the opportunity soil restoration presents for addressing key challenges humanity now faces. Over time, studying how erosion moves rock, sediment and soil to shape landscapes, I became familiar with how soil both influences and reflects the evolution of topography. We’re all familiar with the topographic displays of bare rock in the Grand Canyon, sharp-angled mountain peaks, and the smooth, rounded profiles of soil-mantled slopes in the rolling hills of California. But I also came to notice that prosperous regions tended to have rich, fertile soil. Impoverished ones did not.

Things are not going so well for President Trump’s nominee for the position of under secretary for research, education, and economics (REE) at the US Department of Agriculture. This job has responsibility for scientific integrity at the USDA, as well as oversight of the department’s various research arms and multi-billion dollar annual investments in agricultural research and education that are essential to farmers and eaters alike. The job also encompasses the role of USDA chief scientist, leading Congress in 2008 to emphasize that the person who fills it should actually be a scientist. But Sam Clovis is not one. And that’s not the half of it.

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 >

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.
