Africa’s economic and population growth prospects are likely to increase energy and water demands. This quantitative study shows that energy decarbonisation pathways reduce both water withdrawals and water consumption relative to the baseline scenario. However, the more aggressive decarbonisation pathway (1.5oC) leads to higher overall water withdr...
