Think global, buy local—but better still, choose vegetables and fruit to help slow climate change.

The world’s brewers face paying much higher prices for a key ingredient of beer as climate change hits barley crop yields.

Using less land and having more high-yield farms could be the best answer to the planet’s needs.

New ways of digging the dirt could lead to a major advance, and farmers in the developing world are making a difference.

Higher temperatures mean hungrier insects. And that will mean more crop losses. The question is: Who loses most?

With an estimated 2 billion people already affected by hunger or malnutrition, the results of a recent study raise an alarming prospect.

To cool the world and boost plant growth, such methods may do the trick. But if they work by dimming the sunlight, the plants will ultimately suffer.

The conversion of wilderness for urban growth, agriculture and pasture has already caused losses of perhaps one species in 10 in ecosystems disturbed by humankind.
