在过去的二十年里，哥伦比亚卡克塔河流域下游的土著人民在提供重要生态系统服务方面经历了不利的变化，这些变化对其传统生计的维持产生了重大影响。为了评估这些变化，我们开展了 8 次参与性绘图活动并召开了 22 次焦点小组讨论。我们重点分析两类变化：（1）生态系统服务提供区位置的变化和（2）生态系统服务存量的变化。重点生态系统服务包括提供食物、原材料和药用资源等服务。研究结果表明，在过去二十年中，对粮食和原材料的需求不断增加，因此供应区的位置和生态系统服务的存量发生了变化。我们发现一些轶事证据表明，这些变化与社会经济因素密切相关，例如对创收的更大需求、生计做法和消费模式的变化。我们讨论了参与式绘图技术在边缘化和数据匮乏地区的背景下的使用。我们还展示了此类信息如何加强哥伦比亚亚马逊土著人民使用的现有基于生态系统的管理策略，(C) 2014 作者。由 Elsevier B.V. 出版
Over the last two decades indigenous peoples in the lower Caqueta River basin in Colombia have experienced detrimental changes in the provision of important ecosystem services in ways that have significant implications for the maintenance of their traditional livelihoods. To assess these changes we conducted eight participatory mapping activities and convened 22 focus group discussions. We focused the analysis on two types of change: (1) changes in the location of ecosystem services provisioning areas and (2) changes in the stock of ecosystem services. The focal ecosystem services include services such as provision of food, raw materials and medicinal resources. Results from the study show that in the past two decades the demand for food and raw materials has intensified and, as a result, locations of provisioning areas and the stocks of ecosystem services have changed. We found anecdotal evidence that these changes correlate well with socio-economic factors such as greater need for income generation, change in livelihood practices and consumption patterns. We discuss the use of participatory mapping techniques in the context of marginalized and data-poor regions. We also show how this kind of information can strengthen existing ecosystem-based management strategies used by indigenous peoples in the Colombian Amazon, (C) 2014 The Authors.
