In this project we consider the ways that different livelihood strategies impact the climate-health linkage. Specifically, we build on knowledge of livestock mobility in the Sahel and use remotely sensed-based measures of waterholes with health survey data to investigate the linkages between child health outcomes related to food security. We focus on the landscape characteristics relevant to limitedly studied, but highly climate-vulnerable populations, pastoralists and agro-pastoralists in the Sahel. We combine remotely sensed-based data on surface waterholes and spatially referenced health survey data and use flexible regression modeling techniques to uncover the quantitative relationship between waterhole depth and a child’s height-for-age z-score (HAZ). The results suggest that the water depth level of nearby waterholes does indeed impact a child’s HAZ, even after accounting for other environmental factors. This relationship is impacted, however, by the livelihood practices of the area as well as by the source of household drinking water.

在这个项目中，我们考虑了不同的生计策略影响气候与健康联系的方式。具体而言，我们基于对萨赫勒地区牲畜迁徙的了解，并使用基于遥感的水坑测算与健康调查数据来调查与粮食安全相关的儿童健康结果之间的联系。我们关注与萨赫勒地区有限研究但高度脆弱的人口，牧民和农牧民有关的景观特征。我们将地表水坑的遥感数据与空间参考的健康调查数据结合在一起，并使用灵活的回归建模技术来揭示水坑深度与儿童年龄高度z之间的定量关系得分（HAZ）。结果表明，即使考虑到其他环境因素，附近水坑的水深也确实会影响儿童的HAZ。但是，该关系受到该地区民生习惯以及家庭饮用水来源的影响。
