The Correct Way To Manage And Utilise Groundwater

Around fifty years ago, a large-scale effort was made in South Africa to teach people about water conservation.

Creative slogans such as ‘Save a liter for later’, ‘Make every drop count’ and ‘Water is life’ were commonplace. This campaign, however, was short-lived.

The current drought in South Africa necessitates a renewed effort that will once again teach South Africans to better manage their water affairs. Many people have yet to realize that a water crisis is looming.

The media often cites that 70% of the earth’s surface is covered by water. This is comprised of 97% saltwater and 3% fresh water. Of the 3%, less than 1% is suitable for life on earth. The rest is captured in icebergs in the poles, and cannot be used for human consumption or agriculture.

Severe water crisis

According to a study conducted by the former Department of Water Affairs and Forestry, South Africa could be plunged into a serious water crisis by 2030. This date is not that far off, and drought-stricken farmers are already getting a taste of what it means when water is not properly managed.

Fanie de Lange, a lecturer in geohydrology at the University of the Free State’s Institute for Groundwater Studies (IGS), is involved in research on the detection, determination of sustainability and management of groundwater systems. According to him, the agricultural community recognizes the value of good groundwater resource management, but too many old-fashioned methods are still employed to manage these resources properly and to maximize their lifespan.

Managing water resources

He feels producers should consider the bigger picture when sinking new boreholes or managing their existing resources.
