今年,美国内华达山脉的积雪量创历史新低,而每年的农业用水要消耗掉加州80%的水资源,加之连续四年的严重干旱导致加州正面临着艰难的选择:水究竟优先供给谁?4月1日,加州首次实行了强制性限水措施。针对加州严酷的干旱现实,加州斯坦福大学西部水资源计划执行董事莱昂·西普蒂奇(Leon Szeptycki)在接受《自然》杂志的采访时认为,维持地下水储量是度过干旱期的关键。 This year, the amount of snow in the Sierra Nevada reaches a record low. However, annual agricultural water consumption consumes 80% of California’s water resources. Coupled with four successive years of severe drought, California is facing a difficult choice: Who should give priority to water supply? On April 1, California imposed the mandatory water restriction for the first time. Addressing the harsh drought in California, Leon Szeptycki, executive director of Western Water Solutions at Stanford University in California, told Nature magazine that maintaining groundwater reserves is key to weathering a drought.
