THE ECOLOGICAL, SOCIO-ECONOMIC AND POLITICAL CONSTRAINTS ON PASTORALISTS' ACCESS TO WATER, BLUE NILE STATE (SUDAN).

This article addresses the ecological, socio-economic and political constraints facing pastoralists' water access rights in Blue Nile State, south-eastern Sudan, over the last five decades. It examines the main constraints on pastoralists' access to water and looks at such issues as climate change, increasing human population, the expansion of agriculture, the expansion of Dinder National Park, civil war and the new international border created after the secession of South Sudan in 2011.
