Implementing climate variability adaptation at the community level in the Amazon floodplain

The need to design measures for adapting to climate change is increasingly recognized as important and has encouraged research on the role of local ecological knowledge (LEK) in supporting adaptation. Studies of how LEK can help adapt to increasing climate variability remain limited. This article develops an approach through which the process of adaptation can be tracked at a community level. We describe how community residents in the Amazon floodplains incorporate natural hydrologic and ecological processes into their management systems to optimize ecosystem functioning.We describe two case studies where LEK is used as a resource by small-scale fisher-farmers in the Amazon floodplains to adapt to the increasing impacts on their livelihoods generated by changing climate patterns. This article draws on local histories and seeks to identify the critical factors that either facilitate or impede household ability to reduce their vulnerability. We found that the LEK of small fisher-farmers has facilitated the adaptation of a resource management system to optimize production across a broad range of floodplain habitats and conditions. There are, however, significant challenges to operationalizing these approaches, including an absence of systematically collected data on adaptation strategies and outcomes. In addition, local people must be integrated into policymaking processes so their knowledge can contribute to the design of locally appropriate policies for adapting to the impacts of climate related events.
