About a quarter of the world’s cashews are grown in Vietnam followed by Nigeria, India, and the Ivory Coast.  In Vietnam, drought and unseasonal rains have had detrimental effects on cashew production. The unseasonal rains interfere with pollination and create ideal conditions for insect pests and diseases causing more losses.  In India, cashew crops are at risk due to rising sea levels since the majority of cashew plantations are in coastal regions. Aside from their economic value and unique taste, cashews are an important crop because of the tree’s ability to sequester carbon when grown in high-density environments.  Adoption of improved farming practices are helping to maintain production.

Yields of major staple crops like wheat and rice are being hurt by increasing temperatures. Wine grape production is moving to cooler climes causing changes in the character of some of our favorites. The flavors and health benefits of teas, the size of potatoes, the sting of a hot pepper, where fish call home in the oceans, and a future decline in protein in vegetables—it’s all changing.
