In 2018, drought conditions led to 10 public water supply incidents and 76 water quality issues across England and Scotland. Projections suggest that by the end of the century, warming of 2°C to 4°C could result in a daily water deficit of 1,220–2,900 million litres, with large parts of England and Wales facing shortages. The limited availability of water can affect crucial medical practices, as is already being observed globally. Droughts often coincide with heat waves, exacerbating health impacts for vulnerable groups such as young children, older people, and those with pre-existing conditions. Drought conditions also heighten the risk of wildfires, which worsen air quality and further strain public health systems.
