The global almond boom is being fueled in part by sleek marketing campaigns that have made almonds the nut of choice for consumers. Subway stations in China are blanketed with billboards proclaiming almonds to be a heart-healthy snack that makes people “perpetually feel good” (almond exports to China have more than doubled in the past five years). In Korea, California almonds have been integrated into the storyline of a popular prime-time television show. And in Europe, French and British TV personalities have lauded almonds as a healthy alternative to processed foods.
In the United States, almonds have become a staple for many health-conscious consumers. In its raw form, the “power food” is said to lower cholesterol, spur weight loss, and provide powerful antioxidants such as Vitamin E and manganese. Products like almond butter and almond milk have also become increasingly popular in health food stores.
But growing almonds in an arid climate requires lots of water. In fact, Westlands’ almond orchards suck up nearly 100 billion gallons of water a year. Cotton, by contrast, needs 40 percent less water per acre, and tomatoes require about half as much water as almonds.
Also, unlike cotton and tomatoes, almonds are a “permanent” crop, meaning the land they’re grown on can’t lie fallow when water is scarce. “It means farmers really do need to get a hold of water in dry years in order to keep the trees alive,” explained Ellen Hanak, a senior fellow at the Public Policy Institute of California and an expert on water.
