Drought and Water Scarcity: Understanding the Impact of Climate Change

Drought is a complex phenomenon influenced by both natural factors and human activities. The Met Office has predicted that UK summers are likely to become drier on average due to global warming, although currently, there is no definitive trend.

Rising temperatures play a significant role in accelerating evaporation, leading to moisture depletion from the soil. Professor Richard Allan, a renowned climate scientist from the University of Reading, highlighted, “As the atmosphere warms, there is an increased demand for moisture, resulting in more efficient depletion of water in various sources, which can trigger rapid droughts, heatwaves, and bushfires.”

Apart from temperature rise, other factors such as water usage also impact water scarcity during dry periods. A critical review of the water sector in England and Wales revealed historic underinvestment in water infrastructure by water companies, questioning the effectiveness of current water management practices.

In response to the looming water scarcity crisis, the government and water companies have outlined plans to construct nine new reservoirs in England by 2050, in addition to the ongoing construction of one in Havant Thicket, Hampshire. To address leakage issues and reduce water demand, potential measures like banning hose usage may be considered, as advised by the Environmental Agency.

Furthermore, water companies in Scotland, Wales, and Northern Ireland, whether public or not-for-profit entities, are proactively implementing strategies to safeguard future water supplies and mitigate potential scarcity risks.
