If land degradation continues at the current pace, it is projected that more than half of the cultivated agricultural area in Africa could be unusable by the year 2050 and the region may be able to feed just 25 per cent of its population by 2025.
如果土地退化以目前的速度继续下去，预计到2050年非洲一半以上的耕地无法使用，到2025年该区域可能只能养活25％的人口。
