人们普遍认为，土地利用集约化是实现消除贫穷和避免生态系统服务遭受破坏性损失的全球目标的一项基本战略。本章调查当前的土地利用集约活动是否正在实现这两个目标。为此，它回顾了大量学术文献，这些文献报道了集约化的社会和生态后果的案例研究。主要有两个发现。首先，土地集约利用明显成功实现这些孪生目标的案例相对较少。例如，土地利用集约化带来的短期收入或生产力收益导致生物多样性和生态系统服务的长期减少的情况还有很多。着眼于更长远的视角的研究已经看到，这种取舍如何导致对人类福祉的负面反馈，特别是对被边缘化的社会群体。其次，我们从这些研究中学到的最多的是，a)超越了衡量生产和收入的范围，而是衡量福祉和生态系统服务的多个维度，b)监测较长时期和不同景观的成果动态，以及c)分解成果计量，以确定不同社会群体的成果。
Land use intensification is widely considered to be an essential strategy for achieving global goals to eliminate poverty and to avoid damaging losses of ecosystem services. This chapter investigates whether current land use intensification activities are achieving these twin goals. To do so, it reviews a body of academic literature that reports on case studies in which both social and ecological outcomes of intensification are reported. There are two main findings. First, there are relatively few cases in which land use intensification is clearly succeeding in these twinned objectives. There are many more cases in which, for example, short-term income or productivity gains from land use intensification are resulting in long-term diminution of biodiversity and ecosystem services. Studies with longer-term perspectives are already seeing how such trade-offs are leading to negative feedbacks for human wellbeing, especially for marginalised social groups. Secondly, we learn most from those studies that a) go beyond measuring production and income to measure multiple dimensions of wellbeing and ecosystem services, b) monitor dynamics of outcomes across longer time periods and across landscapes and c) disaggregate outcome measures to identify outcomes for different social groups.
