This CNH project is about livelihood transitions that poor rural communities in developing countries are making in order to cope with deteriorating environmental conditions, shifting social trends, and broader changes in governance. While the transformation of livelihood activities has the potential to improve human well-being, food security, and ecological sustainability, it can also have the opposite effect and increase the vulnerability of the human population and the ecosystems that support them. In the drylands of Africa, about 100 million pastoralists rely heavily or solely on livestock production for their subsistence. Modernization has brought drastic political and social changes, as well as unprecedented population growth, land degradation and more frequent droughts that decimate herds. Today, many pastoralists are adopting crop agriculture alongside their struggling livestock-based livelihood system as an avenue for much-needed diversification. Such a transformation entails profound changes in the ecological functioning of landscapes, the level of risk exposure faced by households and whole communities, and the authorities and rules governing land use and land rights. Given the complexity and novelty of these changes, assessing the conditions under which social and ecological vulnerability is likely to be alleviated or exacerbated is a profound challenge, but is urgently needed as traditional subsistence-level societies worldwide face similarly uncertain futures. This research will assess how the transition to agro-pastoralism in two Maasai communities in Kenya is affecting three components of social-ecological vulnerability: the ecosystem's sensitivity to drought and shifting grazing pressure; the degree of risk exposure that households take on as they make the transition; and the coping capacity afforded by the suite of new rules and practices adopted by the communities. The approach adopted in this research is based on advances in complex systems theory, which can be applied to ecosystems, human interactions, and governance systems alike. This approach is also highly advantageous because it enables the use of information about easily-measured, small-scale interactions to understand and predict broader trends such as tipping points and thresholds, which emerge at the level of the whole social-ecological system. By developing theoretically grounded methods to evaluate multiple dimensions of vulnerability, this research will build transformative links between theory and real-world empirical assessments. It will directly enhance the ability of scientists to understand and solve other complex sustainability problems emerging around the world. Through ongoing participation and dialogue, research procedures and findings will be shared with local community members as tools for empowerment and sustainability planning. Cooperative ties with key colleagues in regional academic, development, and conservation communities will ensure that the research tools developed will enhance the approaches and impact of other sustainability initiatives and research programs. The project's mentored PhD student and postdoc will gain a unique learning experience of the value of science-society collaborations for high-impact research outcomes. This project is supported by the NSF Dynamics of Coupled Natural and Human Systems (CNH) Program.

这个CNH项目是关于发展中国家贫穷的农村社区正在做出的生计转变，以应对环境条件恶化，改变社会趋势和更广泛的治理变化。 虽然生计活动的转变有可能改善人类福祉，粮食安全和生态可持续性，但它也可以具有相反的效果，并增加人口的脆弱性和支持他们的生态系统。 在非洲的旱地，约有1亿个牧民在很大程度上或仅依靠牲畜生产来实现生存。现代化带来了巨大的政治和社会变化，以及前所未有的人口增长，土地退化以及更频繁的干旱，使牛群变得越来越频繁。如今，许多牧民正在采用农作物农业，以及他们挣扎的基于牲畜的生计系统作为急需多元化的途径。这种转变需要深刻改变景观的生态功能，家庭和整个社区所面临的风险暴露水平以及有关土地使用和土地权利的当局和规则。鉴于这些变化的复杂性和新颖性，评估社会和生态脆弱性可能会缓解或加剧的条件是一个深远的挑战，但由于全世界的传统生存水平社会面临类似的未确定未来，因此急需迫切需要。 这项研究将评估肯尼亚两个马赛社区的农业 - 屠宰场的过渡如何影响社会生态脆弱性的三个组成部分：生态系统对干旱和变化的残留压力的敏感性；家庭在过渡时承担的风险暴露程度；以及社区采用的新规则和实践所提供的应对能力。 这项研究中采用的方法基于复杂系统理论的进步，该理论可以应用于生态系统，人类互动和治理系统。 这种方法也非常有利，因为它可以使用有关易于测量的小型相互作用的信息来理解和预测更广泛的趋势，例如倾斜点和阈值，这些趋势在整个社会生态系统的水平上出现。 通过开发理论上扎根的方法来评估脆弱性的多个维度，这项研究将在理论与现实世界经验评估之间建立变革性联系。 它将直接增强科学家理解和解决世界各地其他复杂可持续性问题的能力。 通过持续的参与和对话，将与当地社区成员共享研究程序和发现，作为授权和可持续性计划的工具。与区域学术，发展和保护社区中主要同事的合作关系将确保开发的研究工具将增强其他可持续性计划和研究计划的方法和影响。该项目的指导博士生和博士后将获得独特的学习经验，以了解科学社会合作对高影响力研究成果的价值。 该项目得到了耦合自然和人类系统（CNH）计划的NSF动力学支持。
