Water Usage in Agriculture

Farmers worldwide face water challenges, yet export virtual water through crops. China's milk demand has led to increased imports of alfalfa hay from the U.S., particularly California, which is experiencing severe droughts. Producing milk in China requires significant water, mostly for feed. The agricultural water footprint is a contentious issue, highlighting the need for awareness of water use in food production.
