Minimize Lake Chad

This Landsat-8 image from 4 July 2014 shows Lake Chad in West Africa's Sahel region - a transition zone between the Sahara Desert to the north and savannahs and woodlands to the south.

The lake is the main source of fresh water for over 60 million people in Chad, Cameroon, Niger and Nigeria. It is the main source for the region's irrigation, drinking water for livestock, fishing and supports a rich biodiversity.

The water body is fed primarily by the Chari and Logone Rivers, which are both located in the southwest and flow northward into the lake.

Despite seasonal fluctuations, the surface of Lake Chad has changed enormously in the last decades, with high losses from the 1960s to 1980s, mainly due to a reduction of precipitation induced by climate change, as well as an increased human demand for water.

But recent assessments indicate a turning trend, particularly from 2004 onwards, from rainfall and the subsequent flooding of the surrounding wetlands.
