Water Resource Variability and Livelihoods in the Lower Rufiji Ecosystems (Tanzania) By Mwakipesile Augustino University of Dar es Salaam Tanzania

Introduction Rufiji River maf 800m3 /s River basin surface 180,000 km2 Three dams upstream controlling 23% flow Planned dam to control 95% flow of the river Expected to affect flooding patterns To affect LRE and livelihood strategies of the people

Livelihoods in LRE Floodplain agriculture (94%) of 150,000 pop. Fishing in RR and small lakes (70%) Forests and NTFPs (89%) Wetland cultivation (69%) Small business (33.3% )

Water Resource Variability in LRE Floods ( ) Rainfall ( )

Effects of Water Resource Variability in LRE on Livelihood strategies Floodplain agric-terrace agric (forest decline) Floodplain agric-cultivation along wetlands Long distance to fetch water (women) Decline of floodplain food crop produces Decline in fish catch and stock

Conclusion and Recommendations Collapse of flood dependent livelihoods Decline of delta mangroves (500km2) Biodiversity studies Studies on livelihood strategies Flood release management (for environmental flows and livelihood strategies)
