Combating UK Drought: Restoring Rivers, Recharging Groundwater
2011 was the driest year in England and Wales in 90 years. Drought has been declared in many areas, and a ‘super-drought’ could strike this summer, warns the UK Environment Agency.
Many rivers –including the famous chalk streams—have dried up. Groundwater reserves that feed them are very low. Authorities have even had to rescue and relocate fish from drying river beds!
Restrictions on water use- such as hosepipe bans- have been put in many areas. And rightly so.
However, long term solutions should involve managing the variety of processes that affect river flow and groundwater recharge--agriculture, erosion, runoff, waste management, urban development, river engineering... and many others— as the following videos highlight:
