全球80%的杏仁供应来自美国加利福尼亚州中央河谷地区,但近来加州正面临史上最严峻的旱灾,种植户正想方设法取水灌溉。杏仁在全世界销量日渐增加,已取代花生成为美国人的最爱坚果,在中国的销量也不断攀升,这使得加州的杏仁种植面积一扩再扩,比1996年扩大了两倍多,中央河谷地区的杏仁栽培面积超过了40万hm2。由于杏仁种植面积大幅度增加,这些扩种的果园需要水源,种植户千方百计取水灌溉,包括抽取地下水等,这进一步加剧了加州水供应
Almost 80% of the world’s almonds come from the Central Valley of California, California, but recently California is facing the worst drought in its history, and growers are trying to get water for irrigation.
