  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • The 1996 “Freedom to Farm” Farm Bill

    The period of U.S. farm bills where the instruments were designed around compensation policies that used price support/supply management programs allowing farmers to remain in production during long periods of low prices—the result of four centuries of publicly-sponsored developmental policies—ended with the adoption of the 1996 Farm Bill. In some important ways, the demise of price ...
