Climate, land, energy and water in Cape Town

8 Jul 2016 - 11:45

This 2015 paper, Climate, land, energy and water strategies in the City of Cape Town, just made available, draws largely on a UCT Masters thesis by ERC researcher Fadiel Ajhum. The context of the research is the need to meet development aspirations through growth in industry and agriculture as well as extending basic services to all citizens - with the implications of these at a time when South Africa is already experiencing water shortages.

The City of Cape Town’s surface water-based supply system is highly susceptible to any climate variability, which reduces surface water inflows. The paper first provides an overview of water and energy services within the municipality, then looks at the reliability and energy intensity of supplying water and water services in the CCT under different demand scenarios and with a range of technically feasible supply augmentation options. Demand scenarios include demand-side measures and potential climate change impacts; supply augmentation includes expansion of ground water use, introducing desalination plants and water recycling. There follows a scoping study of competing land uses in the Phillipi horticultural area.
