Food

Forty percent of food produced for consumption never gets eaten, instead filling landfills and releasing greenhouse gases. With a recent law, California aims to drastically reduce the amount of food that ends up in the ground.

A new study co-authored by a Stanford Earth researcher looks at what climate change will mean for global yields of corn, or maize, the most widely grown crop in the world. The study shows dramatic increases in the variability of annual corn yields, which could lead to price hikes and global shortages. 

In one of the first analyses of a company-led sustainability program in the food and agriculture space, Stanford researchers found a major grocery chain fostered increased adoption of environmental practices at the farm level.
