Roof rainwater harvesting is a system where water is stored in an underground water tank. Rainwater flowing over the roof is collected, for example, on galvanised iron roofs. The technology is critical in semi-arid environments where water shortages are common.

The Riaan Dames Grazing Strategy, otherwise known as Split-Ranch Grazing (SRG), is a fundamentally-different technology to grazing management in comparison with popular rotational grazing management systems in many western countries. SRG provides a full-year uninterrupted recovery period for rangeland after grazing.
