英文文献摘要：
In Afghanistan, where 80% of the population is rural, irrigated agriculture is important for satisfying subsistence needs. While most of the irrigated agriculture is fed by diversion canal systems which tap surface flows, legal and physical water infrastructure in the region is generally poor. A math programming model is used to optimize irrigation strategies under different water-availability and policy scenarios. It is found that the construction of a reservoir could increase net revenues to a representative farming community by up to 30%. However, even greater benefits may result from increasing distribution efficiencies, depending on the initial level of conveyance losses. Further, property rights schemes may be implemented to distribute wealth more evenly through various zones at minimal cost to the agricultural community as a whole. These results may prove useful to policymakers or water authorities in reestablishing water rights.
在阿富汗，80%的人口是农村人口，灌溉农业对满足生存需要很重要。虽然大多数灌溉农业是由引水渠系统提供水源的，但该地区的合法和实际水基础设施普遍较差。利用数学规划模型对不同的灌溉策略和政策方案进行优化。研究发现，水库的建设可使具有代表性的农业社区的净收入增加30%。然而，增加分配效率可能会带来更大的利益，这取决于运输损失的初始水平。此外，可以实施产权计划，在不同地区更平均地分配财富，使整个农业社会付出最小的代价。这些结果可能有助于决策者或水当局重建水权。
