How the world needs to change as regions get drier
The University of Cape Town is working with partner organisations in southern, west and east Africa as well as India to investigate how to adapt to climate change in semi-arid regions. In examining various approaches that have already been tried, they identified four types of changes that can be made to adapt to water scarcity. These are:
• Introducing new practices or technologies, such as wastewater reuse
• Doing more of what we’re already doing, for example installing rainwater tanks at people’s homes
• Changing the way water is governed, for example integrated watershed management and more consultative and equal water allocation; and
• Changing social values and attitudes
By combining these interventions, there’s a better chance of managing water sustainably for domestic and agricultural use. They can help increase water supply, improve efficiency and reduce water use.
