A regional scheme to collect, treat and re-use mine water in the Upper Olifants River Catchment has merit, with the mines best placed to start it through a dedicated mine water company that brings in the water services authorities. Water legislation supports the scheme provided the regulator allocates mine water as a resource. Viability rests on the tariffs mines and water users pay.
The impact of cattle grazing on rehabilitated land
Two annual surveys of species composition, biomass and soil sampling inside and outside fenced plots on rehabilitated pasture at an opencast colliery near Ogies, with benchmark sites for comparison.
What this report foundGrazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity.
R1500,00
Grazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity. The sward was dominated by low quality grasses with a high proportion of bare ground and a raised erosion risk. Fenced exclosures over one year changed the abundance of a few species, but the vegetation showed no clear direction of recovery.
