Environmental and Water Science Programme

Water is the cornerstone of life as we know it.  We live in a world where more and more people rely on a limited water supply.  South Africa with an average annual rainfall of 500mm has limited water resources. If we do not understand our water resources and the environments where they occur, we cannot manage them and then will be heading for disaster.

If you are interested in the interaction of humans with the environment, the processes operating in the environment and affecting our water resources and the influence of natural phenomena on the environment, this degree is for you.

We build skills to assess and manage environmental issues related to surface water, groundwater, soils, climate and land use. Our modules focus, amongst others, on:  

  • The protection of our water resources from over-exploitation and pollution.
  • Understanding soils for conservation and erosion control and food security.
  • Land, water and vulnerability assessments using Geographical Information Systems for map creation
Degrees Offered
  • B.Sc (Environmental and Water Science)
