With population growth, changing weather patterns including hotter summers and drier winters, water is becoming increasingly vulnerable to scarcity, even in the UK. That will mean more water shortages: by 2050, the amount of water available could be reduced by 10-15%, with some rivers seeing 50%-80% less water during the summer months. It will mean higher drought risk, caused by the hotter drier summers and less predictable rainfall. On the present projections, many parts of our country will face significant water deficits by 2050, particularly in the south east where much of the UK population lives.
