Household adaptation amongst hot spots of land degradation vulnerability and bright spots of resilience

是什么导致了土地退化？人们如何应对气候变化在地区、次国家和地方层面的影响和后果？什么反应对人类和自然都是有弹性的？为了解决这些问题，本项目开发了一种新的方法，利用全球现有数据，确定生态条件和人类复原力改善的新“亮点”，以及土地退化和人类脆弱性的新“热点”，以揭示与人类和生态复原力相关的因素。本研究通过对比具有相似生态和社会经济条件的亮点地区和热点地区的驱动因素和应对措施，找出亮点地区的有效措施，并将其转化为热点地区的行动计划。这项研究对森林砍伐和土地变迁以及人类适应反应的理论提出了挑战。该项目将住户调查和社区访谈与无人机获取的图像结合起来，这些图像嵌套在“亮点”和“热点”中。研究结果可以确定可以复制的潜在行为和做法，以提高全球热带森林边境地区的家庭和生态恢复力。该项目提高了对社会和生物物理系统组成部分之间相互作用的理解，有助于为联合国成员国提供监测和评估信息，以实现联合国可持续发展目标（sdg）和联合国荒漠化公约（UNCCD）关于荒漠化、土地退化和干旱的战略目标。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
