在肯尼亚Baringo湖周围的半干旱稀树草原，外来入侵物种Prosopis juliflora和本地Dodonaea viscossa最近蔓延的灌木入侵改变了人与环境的相互作用。这篇文章提出了如何传播的动态牧豆属和Dodonaea已经运作。它还描述了巴林戈人民面对这种戏剧性的丛林入侵所采取的策略，将这些动态与当前的入侵理论联系起来，并分析了对巴林戈社会生态系统可能产生的影响。有人认为，最近增加的气候变异性引发了巴林戈湖周围的土地管理和生计的变化，为灌木入侵和物种入侵铺平了道路。这些变化的范围和速度超过了当地社区调整其生产系统的能力，破坏了巴林戈湖周围旱地稀树草原的社会生态稳定，使这些草原面临崩溃的紧迫危险。
In the semi-arid savannahs around Lake Baringo, Kenya, the recent spread of bush encroachment by the invasive alien species Prosopis juliflora and the native Dodonaea viscosa has changed human-environment interactions. This article suggests how the spread dynamics of Prosopis and Dodonaea have operated. It also describes the strategies Baringo's peoples have adopted in the face of this dramatic bush invasion, relates these dynamics to current invasion theory, and analyses possible implications for Baringo's social-ecological systems. It is suggested that recent increased climate variability has triggered changes in land management and livelihoods around Lake Baringo, paving the way for bush encroachment and species invasion. The extent and speed of these changes has exceeded the capacity of local communities to adapt their productive systems, destabilizing the socio-ecology of the dryland savannahs around Lake Baringo and placing them in imminent danger of collapse.
