Tanzanian President John Magufuli downplayed fears Tuesday that a hydro-electric dam planned for a fabled nature reserve would affect the environment, despite Unesco expressing "grave concern" over the scheme.
The 2,100-megawatt scheme will straddle the Rufiji River in the Selous Game Reserve, a 50,000-square-kilometre (19,000-square-mile) protected area which was designated a Unesco World Heritage Site in 1982.
