Seawater desalination – the process of removing dissolved salts and other minerals from seawater, making it suitable for drinking or irrigation – has the potential to be a climate adaptation investment opportunity in certain African countries, according to a new report by British International Investment. Climate change, economic growth, and rapid rates of urbanisation that outpace infrastructure development, mean that demand and supply of freshwater is set to become the challenge of the century. Africa is one focal point of the water crisis. Arid regions of North Africa tend to experience physical water scarcity from low water availability, whereas sub-Saharan countries mainly suffer from economic water scarcity, which is linked to poor governance, poor infrastructure and limited investments. Unconventional water sources, such as desalination, are increasingly relevant to support water security in Africa. Desalination has the potential to increase the resilience of water systems by producing water independently of climatic and hydrological conditions. Although it largely uses seawater, desalination can be applied to a range of other water sources, including brackish groundwater, surface water, and domestic or industrial wastewater. Seawater desalination is set to play an important role in helping to alleviate the water crisis. In Africa, the coastal […]
