This independent technical review assesses the “Strategic environmental assessment report for the proposed Rufiji hydropower project”, dated April 2019, that relates to the planned Rufiji River Hydropower Project (RRHP). The RRHP comprises a 130m high dam on the Rufiji river at Stiegler's Gorge, creation of a 100km long, c.914km squared reservoir plus power plant, a transmission line, workers camps and access roads, all of which will be within the Selous Game Reserve, a natural World Heritage site. This review follows a similar format to, and builds upon, the independent technical review of the Project EIA commissioned in April 2019 by IUCN.
