What this report found

Cynodon dactylon outperformed Themeda triandra and Hyparrhenia hirta, reaching 100 per cent survival and cover at all three trial sites by 2007 with or without fertiliser. Acacia sieberana reached 97 per cent survival at Kleinkopje Colliery but grew poorly at Optimum and Syferfontein. Planting plugs suits slopes too steep for a planter machine and buffers against pasture grass intrusion.

What this report found

Conventional cost accounting at the mines studied could not report on physical structure or materials flow, so environmental costs such as water, energy and consumables stayed hidden and chances to cut them were lost. Four case studies across different commodities and mining methods showed the same limitations. An environmental management accounting model is proposed to identify and allocate those costs.
