Desertification, brought about by human-induced factors and climate change,

问题     Desertification, brought about by human-induced factors and climate change, is a land degradation process. Human activities such as over-cultivation and poor irrigation methods are turning quickly into barren patches of land fertile soils that take centuries to form. Without access to sustainable land use practices, poor farmers are reduced to cultivating degraded land, only to initiate a vicious cycle, which is why tackling rural poverty is critical to combating desertification. No long-term strategy of poverty elimination can succeed in the face of the environmental forces that promote persistent erosion of soil. Under current projections of climate change, the hardship and human loss caused by droughts could increase if its contributing factors are left unaddressed.
选项
答案     沙漠化是由人为因素和气候变化造成的，是土地退化的一个过程。过度开垦和落后的灌溉方法等人类活动正在把需要几百年才能形成的肥沃土壤变成贫瘠的地块。由于缺乏可持续使用土地的方法，贫困的农民只好开垦退化的土地，结果却导致恶性循环，所以说解决农村贫困问题是抗击沙漠化的关键。只要促使水土不断流失的环境力量存在，任何一个长期扶贫战略都不会成功。根据目前对气候变化的预测，如果促成气候变化的因素得不到解决，干旱引发的困难和人类遭受的损失就有可能增加。
