What drives land degradation? How do people cope with its impacts and consequences across regional, sub-national, and local scales? What responses are resilient for both humans and nature? To address these questions, this project develops a novel methodology, using globally available data, to identify emerging “bright spots” of improving ecological conditions and human resilience and emerging “hot spots” of land degradation and human vulnerability to reveal factors associated with human and ecological resilience. By contrasting drivers and responses in areas of bright spots and hot spots with similar ecological and socio-economic conditions, the research identifies and translates what worked in bright spots into action plans for hotspot areas. The research has important implications for challenging theories on deforestation and land transitions as well as human adaptive responses. This project integrates household surveys and community-level interviews with drone-derived imagery nested within “bright spots” and “hot spots”. Results may identify potential behaviors and practices that can be replicated to improve household and ecological resilience in tropical forest frontiers globally. The project improves understanding of interactions among social and biophysical system components that can help inform United Nations (UN) member nations of monitoring and evaluation towards achieving UN Sustainable Development Goals (SDGs) and the UNCCD Strategic Objectives for desertification, land degradation, and drought.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

是什么导致了土地退化？人们如何应对其在区域、国家以下和地方范围内的影响和后果？为了解决这些问题，该项目使用了全球可用的新方法。通过对比亮点和热点地区的驱动因素和响应，识别改善生态条件和人类复原力的新兴“亮点”以及土地退化和人类脆弱性的新兴“热点”，揭示与人类和生态复原力相关的因素。研究确定，具有相似生态和社会经济条件的地点并将亮点中的成果转化为热点地区的行动计划，该研究对于挑战森林砍伐和土地转型以及人类适应性反应的理论具有重要意义。该项目将家庭调查和社区层面的访谈与无人机衍生的图像结合起来。结果可能会确定可复制的潜在行为和做法，以提高全球热带森林边界的家庭和生态复原力，从而有助于了解社会和生物物理系统组成部分之间的相互作用。联合国(UN) 成员国对实现联合国可持续发展目标 (SDG) 和荒漠化、土地退化和干旱的《联合国防治荒漠化公约》战略目标进行监测和评估。该奖项反映了 NSF 的法定使命，并被认为值得通过使用基金会的评估进行支持智力价值和更广泛的影响审查标准。
