砍伐森林和景观破碎化被认为是导致人畜共患传染病直接传播的过程。某些人类行为为人类和野生非人灵长类动物（NHP）之间的直接接触提供了机会，但在将景观水平因素与观察到的传染病联系起来的研究中往往缺失。目标我们的目标是更好地了解景观和生计因素影响人的NHP接触在农村社区的景观经历砍伐森林。我们调查的核心损失和边缘密度在一个缓冲区内的受访家庭，以确定哪些景观变化和行为增加人类NHP接触的风险。方法行为调查数据收集自乌干达西部基巴莱国家公园附近森林片段的小规模农民。我们将空间上明确的行为数据与高分辨率卫星图像相结合。使用土地覆盖分类和变化检测，我们调查了森林损失和破碎化，行为数据，人类NHP接触，使用逻辑回归之间的关系。结果在2011年至2015年期间，与那些没有接触过人类NHP的人相比，经历过人类NHP接触的人的家庭周围的景观指标存在差异。家庭周围边缘密度的增加，建筑用小树的收集，以及在森林栖息地觅食和狩猎食物显着增加了人类与NHP接触的可能性。结论森林景观破碎化和小农户行为共同增加了人类与NHP接触事件的可能性。结合土地利用和人类行为的空间明确的数据是至关重要的，了解社会和生态的驱动因素，人类NHP接触。
Context Deforestation and landscape fragmentation have been identified as processes enabling direct transmission of zoonotic infections. Certain human behaviors provide opportunities for direct contact between humans and wild nonhuman primates (NHPs), but are often missing from studies linking landscape level factors and observed infectious diseases. Objectives Our objective is to better understand landscape and livelihood factors influencing human-NHP contact in rural communities whose landscapes undergo deforestation. We investigate core loss and edge density within a buffered area around survey respondent households to identify which landscape changes and behaviors increase the risk of human-NHP contact. Methods Behavioral survey data were collected from small-scale agriculturists living near forest fragments around Kibale National Park in western Uganda. We combined spatially explicit behavioral data with high-resolution satellite imagery. Using land cover classification and change detection, we investigated the relationships between forest loss and fragmentation, behavioral data, and human-NHP contact using logistic regression. Results Between 2011 and 2015, there were differences in the landscape metrics around the households of individuals who had experienced human-NHP contact compared to those who had not had contact. Increased edge density around households, collection of small trees for construction, and foraging and hunting for food in forested habitat significantly increase the likelihood of human-NHP contact. Conclusion This study provides empirical evidence that forest landscape fragmentation and certain smallholders' behaviors in forest patches jointly increase the likelihood of human-NHP contact events. Combining spatially explicit data on land use and human behaviors is crucial for understanding the social and ecological drivers of human-NHP contact.
