Lake Tanganyika, the biggest freshwater lake in the Great Lakes region, is a source of livelihoods and access to water for a significant number of people. The impact of climate change on its water levels therefore poses significant threats to populations living on the lake’s coast and close to its basin. Communities in Burundi and in the United Republic of Tanzania are particularly exposed to climate-induced hazards resulting from lake water rise (for instance, flooding). The increase in severity and frequency of those hazards in recent years require a substantial increase in community resilience and preparedness for response capacity at all levels. This project aims to contribute to strengthening the resilience of the Lake Tanganyika basin communities to cope with the effects of climate change by promoting sub-regional collaboration on preparedness and mitigation actions. To achieve this, a two-pronged approach is planned. First, support will be given to relevant government stakeholders to prepare responses to migration-related challenges posed by climate change in the Lake Tanganyika basin (Outcome 1). In addition to assisting in the development of a gender-sensitive Joint Action Plan to address challenges posed by the rising water of Lake Tanganyika (Output 1.1), workshops will be organized to strengthen the capacities of local government actors and other key stakeholders in planning for, and collaborating to address, challenges posed by climate change and disaster-induced migration (Output 1.2). In tandem, support will be provided to communities in impacted regions so that they actively participate in disaster risk reduction and mitigation activities to prepare for and address climate-related hazards and subsequent displacement (Outcome 2). In practice, the capacities of communities in targeted areas will be strengthened with access to information on risk reduction, in line with the joint action plan recommendations (Output 2.1). Additionally, gender-sensitive, nature and community-based mitigation initiatives will be implemented to best meet these communities’ needs (Output 2.2).
