MADISON, WI, August 9th, 2010 – Greenhouse gas markets, where invisible gases are traded, must seem like black boxes to most people. Farmers can make money on these markets, such as the Chicago Climate Exchange, by installing methane capture technologies in animal-based systems, no-till farming, establishing grasslands, and planting trees. Farmers, students, extension educators, offset [...]

Agriculture has changed dramatically, especially since the end of World War II. Food and fiber productivity soared due to new technologies, mechanization, increased chemical use, specialization and government policies that favored maximizing production. These changes allowed fewer farmers with reduced labor demands to produce the majority of the food and fiber in the U.S. Although [...]

Kathleen O’Hara Like most city dwellers, my knowledge of farming is embarrassingly limited. But a conference on agriculture and global warming has inspired me to dig deeper (pun intended) into things rural. The speaker who grabbed my urban-oriented attention was American-born, U.K.-based Craig Sams, co-founder of Green and Black’s organic chocolate bars. His message was, [...]

By Nicole Schuetz Better farming practices can improve crop yield and lock up greenhouse gases Everybody knows plants store carbon. But soils do too. That’s the idea behind organic no-till farming, a cultivation technique that could dramatically increase soil carbon storage across the globe. Research has shown organic farming methods sequester more carbon per acre [...]
