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.

是什么驱动土地退化？人们如何应对区域，次国和本地规模的影响和后果？哪些反应对人类和自然都具有弹性？为了解决这些问题，该项目使用全球可用的数据开发了一种新颖的方法，以确定新兴的“亮点”，以改善生态条件和人类的韧性以及新兴的土地退化的“热点”，以及人类脆弱性，以揭示与人类和生态弹性相关的因素。通过与与生态和社会经济状况相似的亮点和热点地区的驱动因素和反应进行对比，研究将亮点中有效的东西转化为热点地区的行动计划。这项研究对挑战理论的森林砍伐和土地过渡以及人类适应性反应具有重要意义。该项目将家庭调查和社区级的访谈与嵌套在“亮点”和“热点”中的无人机衍生的图像进行了整合。结果可能会确定可以复制的潜在行为和实践，以改善全球热带森林边界的家庭和生态弹性。该项目提高了对社会和生物物理系统组成部分之间的互动的理解，这些组件可以帮助联合国（UN）成员国进行监测和评估，以实现未能达到可持续发展目标（SDGS）以及UNCCD的沙漠化，土地退化和干旱的战略目标，并反映了NSF的法定宣传和诚实的授权。 标准。
