Reinventing Farming for a Changing Climate
Scientists say climate change could increase pests and weeds, lengthen growing seasons, and turn dry soil to dust. Farmers are already on the offensive, adopting no-till cropping methods to conserve water and experimenting with different seeds. And scientists are using a technique called gene silencing to develop new crops—without tinkering with the plants’ DNA.
