"climate smart" practices

Higher ag productivity may be cheapest way to reduce carbon emissions

The least expensive way to attack greenhouse gas emissions on the farm may be larger investment in agricultural research and development, said University of California professor Aaron Smith in a blog on Tuesday. He cited a 2010 study that estimated agricultural R&D reduced carbon emissions through higher productivity at a cost of $15 per ton, "a much lower cost" than some commonly suggested practices, such as cover crops and conservation tillage.
