The national drought group – which includes the Met Office, regulators, government, water companies and other organisations – has met as five areas of the country remain in drought, with six more in prolonged dry weather status.
England is seeing widespread environmental and agricultural impacts from the lack of water, which is hitting crop yields, reducing feed for livestock, damaging wetlands and river wildlife, and increasing wildfires, the group said.
