“…The Blesbok Spruit wetland has been recognized as a wetland of international importance and consequently been given Ramsar status since 1986 [22][23][24][25]. The catchment is enclosed by large areas of formal and informal urban developments.…”

“…It was consequently put on the Montreaux Record in 1996 and is now characterized by poor water quality, a continuing decline of ecological health and a declining bird population [22][23][24][25]. The degradation of the Blesbok Spruit wetland in terms of its ecological health is of prime importance and needs to be deemed as significant as the wetland could aid in the destruction of coliform organisms and enhance the pollution assimilation capacities of urban drains but also contribute to the buffering capabilities of the catchment [26].…”

Abstract:The integrity of the Blesbok Spruit catchment has been significantly compromised over the past decades, mainly due to the discharge of mining effluent and sewage. This research investigated the hydrological responses, in terms of water quality, in the event of land cover change within the catchment to make predictions on the future sustainability of the region's water resources with the application of Partial Least Squares (PLS) regression analysis. The quantification of hydrological responses in terms of water quality towards land cover changes has not been completed by previous research studies within the catchment. This research established the catchment's present state of water quality and formulated PLS model equations to enable the prediction of future concentrations of specific water quality parameters in association with future land cover change. A change in land cover was found to have various negative influences. The retransformation of land cover into natural areas is accompanied with unintended and undesirable effects due to the degradation of the catchment's buffering capabilities and the absence of the enforcement of the decommissioning of mining operations. For the Blesbok Spruit catchment to avoid a future water predicament, systematic and interdisciplinary measures need to be implemented OPEN ACCESSWater 2014, 6 2947 according to these and other related findings, to ensure the future sustainability of the catchment and the region as a whole.

Restricting access to wilderness and wildlife resources is a contested topic in a time when developing nations are seeking to increase quality of life for their citizens. A case in point is the Mkuze Game Reserve which encompasses rich biodiversity and is surrounded by under-resourced rural communities. A history of exclusion from land and resources has left local residents feeling negative about western conservation ideals. Perceptions of protected areas and conservation objectives are important if management authorities are to affect a meaningful buy-in to conservation and sustainable resource use among local residents. In this paper, part of a larger mixed-methods study, we set out to explore the perceptions three rural communities have of 1) local land-cover and livelihood change and 2) the socio-economic benefits expected and derived from living adjacent to Mkuze Game Reserve, a publicly administered protected area in KwaZulu-Natal, South Africa. People living around the reserve felt they receive few benefits from living near to a protected area. Management countered that they are not well funded enough to provide much development support. In addition to this, the community sees a contrast between this lack of benefit sharing and the successful benefit sharing experienced by a neighbouring community which borders a private reserve. This has added to their negative view of the way Mkuze Game Reserve management has been engaging with communities. Effective engagement with communities and understanding their expectations will be important for strengthening conservation initiatives and community engagement objectives in the area.

“…The Blesbokspruit catchment has in it an important and international wetland covering an area of about 1858 km 2 with a Ramsar recognition dated as far back as 1986. This wetland has a gold mine tailing dump located very close to it and provides support and habitat to several species of birds and plants [16]. Extended part of the study area is used for agricultural activities such as cultivation of crops and rearing of animals.…”

In this study, the selected streams within the Blesbokspruit located in South Africa were characterised in this study. Because of prolonged mining activities coupled with ineffective management practices, several mine tailing (MT) dumps are widely distributed in this area. Metals and metalloid contamination from these tailing facilities have been reported to be major contributors to environmental hazards such as acid mine drainage (AMD). With increased agricultural activities in this area, an assessment of the general quality of water being utilised for irrigation purposes and feeding of farm animals becomes inevitable. A procedural method was implemented in a bid to identify relations between tailing and stream water contamination. Representative gold tailing sediments and water samples were collected, respectively. With the aid of X-ray fluorescence (XRF) and X-ray diffraction (XRD), the mineralogical characterisation of the tailing sediments was successfully carried out, while acid digestion using inductively coupled plasma-optical emission spectrometry (ICP-OES) was utilised in the determination of trace metal contents. Samples of different water sources were also characterised. There was a clear description of the link between tailings, water contamination and possible implications to animals and humans in the long run.
