California is the only state in the country that produces almonds on a commercial scale which amounts to 82 percent of the entire world’s almond production. However each almond requires approximately 1.1 gallons of water to produce. Furthermore, 44 percent more land in California is being used for almond farming compared to 10 years ago. This comes on the heels of one of the worst droughts in the state’s history.
The massive amount of water being used to produce almonds is being diverted from the Klamath River in northern California which is having adverse affects on salmon populations and creating other ecological problems. The salmon – which are swimming upstream to reach breeding grounds – could succumb to a disease known as gill rot if river levels remain low.
California produces 99 percent of the almonds consumed in the United States. The Golden State also farms 99 percent of the country’s walnuts – which require 4.9 gallons of water per walnut – as well as 98 percent of the county’s pistachios which need three-quarters of a gallon of water for each nut.
Despite the drought, this year California’s almond farmers are expected to see their most productive harvest to date, according to the state’s Department of Agriculture.
