Lake Tanganyika: Status, challenges, and opportunities for research collaborations

Lake Tanganyika is one of the most important lakes in the world because it supports millions of people who rely on its resources and its exceptional biodiversity. However, the lake currently suffers from a range of anthropogenic stressors, including water pollution and sedimentation, resource, biodiversity decline, habitat loss (both physical and functional) and climate change. Past and current research has been limited and disparate, only allowing the scientific community to gather inadequate data required to make informed policy and management plans for this lake. Based on data and knowledge derived from scientific studies and field experiences by scientists and experts working in the Lake Tanganyika basin, this paper outlines past research, present gaps, and the opportunities for collaboration to generate scientific knowledge to inform positive policy and management strategies leading to the protection of Lake Tanganyika’s ecological integrity. The results of this paper draw from independent short surveys, freshwater expert meetings, and formal and informal discussions carried out to identify and prioritize specific issues and threats that need to be addressed for the conservation of biodiversity and sustainable management of the Lake Tanganyika basin. After highlighting each issue or threat, the authors propose possible management interventions; the results of this work focus heavily on the need for enhanced specific research on many issues and a larger, multi-disciplinary, long-term monitoring program to collect comprehensive information on a host of variables that will ultimately assist relevant stakeholders and key agencies in addressing these issues and threats.
