Abstract Increasingly, resource managers and planners seek to manage forested landscapes for the value of the services they provide. This is especially true in the Mau Forest of Kenya, a montane area that harbors some of Kenya’s most important headwaters but has lost a quarter of its forest cover since 1999. While managing for the Mau Forest’s landscape services is a priority, it is critical to understand why and how people value these services differently. Otherwise, land management policies risk exacerbating rather than alleviating conservation and environmental justice problems. This is particularly true of provisioning services, a category of landscape services on which communities directly depend. This research combines participatory mapping and semi-structured interviews to understand how socio-cultural values of provisioning services are distributed across two sites within the Western Mau Forest and analyze linkages between mapped values, their locations, and influencing factors. In total, 55 informants were interviewed. Frequently listed provisioning services were water, firewood, cultivation, grazing, timber, and medicine. Results indicate that four main factors influence the location from where these services were derived: historical and legal arrangements, social relations, economic conditions, and biophysical conditions. How these factors influence where people value provisioning services differ based on the service and community in question. This study demonstrates that communities can use and value provisioning services differently and that the distributions of these services are influenced by the factors mentioned above. Understanding this heterogeneity can enable managers and policy makers to create local land use plans that account for spatially-explicit values.

在东非山地森林景观中提供服务价值的空间分布和感知驱动因素

摘要 资源管理者和规划者越来越多地寻求管理森林景观，以实现其提供的服务价值。肯尼亚茂森林尤其如此，该山区拥有肯尼亚一些最重要的源头，但自 1999 年以来森林覆盖面积已减少了四分之一。 虽然管理茂森林的景观服务是当务之急，但至关重要的是了解人们为何以及如何以不同的方式评价这些服务。否则，土地管理政策可能会加剧而不是减轻保护和环境正义问题。供应服务尤其如此，这是社区直接依赖的一类景观服务。本研究结合了参与式制图和半结构化访谈，以了解供应服务的社会文化价值如何分布在西茂森林内的两个地点，并分析制图价值、它们的位置和影响因素之间的联系。总共采访了55名知情人。经常列出的供应服务是水、木柴、种植、放牧、木材和医药。结果表明，有四个主要因素影响这些服务的来源地：历史和法律安排、社会关系、经济条件和生物物理条件。这些因素如何影响人们对供应服务的重视程度取决于所讨论的服务和社区。本研究表明，社区可以以不同的方式使用和评估供应服务，并且这些服务的分布受上述因素的影响。了解这种异质性可以使管理人员和政策制定者能够制定考虑到空间明确价值的当地土地利用计划。
