Natural phenomenon such as droughts have a definite influence on the availability of water sources, soil profiles and vegetation of an area. Man should adapt his activities, such as farming, to the current climatic elements of the area to ensure his existence. Intermittent rainfall and the occurrence of droughts caused symptoms such as desertification. Desertification has reached an alarming level in South Africa, so much so that the level of environmental degradation in the Northern Cape Province caused great distress. This caused many questions into the activities of man in this area. The problem that arose out of this is, does man cause a negative impact on the environment with his farming activities?
The specific area of concern is the Southern Kalahari-dunefield, with its unique ecosystems. This area can be described as an semi-arid desert with very sensitive ecosystems. Any form of interference can cause a long term ecological disruption. This area contains several hidden resources which are optimally used by man and animals to live a decent life. The development of these resources (e.g. water) over the past decades lead to the advantage for all concerned. However, the real danger of over-utilisation and exploitation do exist.
Questionnaires were used to gather data concerning stock farming activities in this area. Information was obtained regarding water resources, vegetation cover, endemic animals, type of farming, ground cover and other economic activities such as tourism.
Man is an additional determinant who causes an impact on his environment in the Southern Kalahari-dunefield. Although a change can be observed over the past decades in the activities of man to enhance sustainable development, continuous strive to the implementation of new methods to preserve resources in the long term, must be encouraged.
