Desertification refers to the development of desert-like conditions in an area and more so in a region adjacent to a desert. It may be expressed as the advancement or extension of the desert. Desertification has been commonly experienced in the Sahel region of Africa. In East Africa desert-like conditions have been experienced or developed in parts of Northern Kenya, Central and Northern Tanzania, N. Eastern Uganda, and the Ankole-Masaka corridor and parts of Western Uganda adjacent to Lake Albert, Lake George, Albert Nile, and within the East African rift valley.

9 Indicators of desertification 

  • Decreasing rainfall amounts.
  • Rainfall becomes more unreliable i.e. more recurring cycles of drought start being experienced.
  • Increasing temperatures i.e. temperatures tend to rise.
  • Reducing relative humidity i.e. the amount of water vapour in the atmosphere reduces.

  • Increasing diurnal range of temperature.
  • Reducing thickness of cloud cover i.e. the skies tend to become clearer and clearer with each passing year.
  • There is loss of water retention capacity of the vegetation and soils i.e. there are increasing evapotranspiration rates. 
  •  Reduced bio-diversity i.e. there is degradation of the biological productivity of the land i.e. reduced plant and animal species.
  • Increasing wind and run off erosion hence consequently resulting into reduced soil fertility.
