A DPSIR and SAF Analysis of Water Insecurity in Lake Chad Basin, Central Africa

<p>Lake Chad is a transboundary freshwater body located in the extreme south of the Sahara Desert. Many centuries ago, the synergies between nature and human activities in the basin were in harmony; and nowadays, the manifestation of unsustainable human activities and drier climate in the basi...
