In Brazil, a water-conservation fund is working to restore the Cantareira watershed, the source of 50% of Sao Paulo’s water. The area has lost 70% of its original forest cover, and sediment from eroding hillsides has clogged the city’s reservoir, jeopardizing the water supply of Brazil’s largest city.
在巴西，一家节水基金正努力恢复为圣保罗提供50%水源的康达雷拉流域。该地区森林覆盖率已经下降70%，而且山体侵蚀带来的沉积物已经堵塞了城市水库，从而对巴西最大城市的供水安全构成威胁。按照新计划，农牧民每公顷能拿到120美元，用于植被恢复和梯田改造工作。到目前为止，已经有3，500公顷土地种植了树木，或者实行了经过改良的土壤管理措施。另外造林14，200公顷可以减少流域内半数的泥沙沉积。
