Future global urban water scarcity and potential solutions
The study projects a significant increase in the global urban population facing water scarcity, from 933 million in 2016 to 1.693-2.373 billion by 2050. The majority of water-scarce cities could potentially alleviate their scarcity through various solutions, but several large cities, particularly in India and Pakistan, face significant challenges due to geographical and socioeconomic constraints. The research emphasizes the importance of water conservation, controlled urbanization, and climate change mitigation in addressing this growing issue.
