撒哈拉以南非洲的农村社区依靠提供生态系统服务（ES）来支持他们的生计，但在土地利用发生快速变化的地区，环境变化，提供ES可用性和生计之间的关系尚未完全了解。这种关系在坦桑尼亚西南部的一个典型的农村miombo林地景观中进行了探索，由于烟草种植的扩大，该景观正在经历快速的土地利用变化。使用混合方法探索了所使用的预配ES的类型、使用者、可用性的变化以及这些变化未来可能产生的影响。我们的研究结果确定了19个供应ES家庭使用，无论经济地位。几乎所有家庭都使用木柴、建筑材料和淡水，而且据认为这些的供应正在减少。家庭认为这是一个负面的环境影响的土地利用变化，并提供ES损失将是“坏”的家庭。鉴于miombo林地的多用途性质，适应性共同管理方法可以通过鼓励当地社区的参与，学习和赋权来实现多个目标，这可能是实现可持续土地利用管理和维持撒哈拉以南非洲miombo林地景观中ES的适当策略。
Rural communities in sub‐Saharan Africa rely upon provisioning ecosystem services (ES) to support their livelihoods, yet in areas where rapid land use change is occurring the relationship between environmental change, provisioning ES availability and livelihoods is not fully understood. This relationship is explored here within a typical rural miombo woodland landscape in south‐west Tanzania, which is undergoing rapid land use change due to expanding tobacco cultivation. The types of provisioning ES used, who uses them, changes in their availability, and the possible future impacts of these changes were explored using a mixed‐method approach. Our findings identify 19 provisioning ES used by households regardless of economic status. Firewood, building materials, and fresh water are used by almost all households, and these are perceived to be declining in availability. Households identified this as a negative environmental impact of land use change and that provisioning ES loss would be ‘bad’ for their households. Given the multi‐purpose nature of miombo woodlands, an adaptive co‐management approach, which can achieve multiple objectives through encouraging participation, learning, and empowerment of local communities, could be an appropriate strategy to achieve sustainable land use management and maintain the provision of ES within miombo woodland landscapes of sub‐Saharan Africa.
