英文文献摘要：
This study investigated the private and social returns to Sustainable Land Management (SLM) practices with an objective of finding practices that reduce the on-farm and off-farm negative effects of land degradation. The results show that SLM practices have robust profits for farmers raising dairy cows. Farmers without dairy cows realize profits that are sensitive to input and output prices. Adoption of SLM also provides global environmental services whose value is about 10% of the net present value. The results suggest the need to promote SLM practices with multiple uses and consider ways to compensate farmers who offer significant environmental services.
本研究调查了私人和社会对可持续土地管理(SLM)实践的回报，目的是找到减少土地退化对农场和非农影响的实践。结果表明，SLM实践为奶牛养殖户带来了丰厚的利润。没有奶牛的农民实现的利润对投入和产出价格很敏感。采用SLM还提供全球环境服务，其价值约为净现值的10%。研究结果表明，有必要推广具有多种用途的SLM做法，并考虑对提供重要环境服务的农民进行补偿。
