Where has a drought been declared, and what does it mean?

A drought has been officially declared across the West Midlands.

It's the tenth area of England to be given drought status by the Environment Agency.

The move follows an unusually dry period with higher-than-average temperatures.

Along with a large part of South-west Wales, ten areas of England are currently in drought:

Separately, Northern Ireland Water has asked the UK government to put drought order measures in place.

The Scottish Environment Protection Agency temporarily banned farmers in parts of Fife from using water from the River Eden on their fields.

The Environment Agency (EA) decides whether to declare a drought after speaking with water companies, government officials and groups including famers' representatives.

It looks at data including rainfall, river flows, groundwater levels, reservoir levels, and the dryness of soils.

The EA's latest water situation report shows some river levels are the lowest ever recorded.

Declaring a drought in a specific area does not oblige water companies to restrict water use.

However, it means they put into operation pre-arranged drought plans, which may include temporary use bans on things like hosepipes and lawn sprinklers.

Hosepipe bans are now in place across much of England and part of Wales.

Other possible options include:

The Environment Agency is also urging water companies to act to reduce leakage from pipes as quickly as possible.

In the first three months of the year, England's rainfall was down 26% while in Wales it was down 22%.

This meant that even before the summer had started, average river flows were "below normal" or "exceptionally low".

In July, rainfall was a quarter of the normal level.

Overuse of water has made the situation worse. The government says over a quarter of the UK's underground water sources have too much water taken from them.

The effects of drought can include:

Berry farmers have reported losing some of their crop.

Vegetables such as potatoes are at particular risk because of their high-water content.

Farmers are delay planting crops for next year such as rapeseed because of the dry soil.

Sheep and lambs are suffering from undernourishment.

There have been multiple fires, with significant damage to homes and grasslands.

London Fire Brigade dealt with 340 grassland fires in the first week of August - eight times as many as they had to deal with in the same week last year.

Because of the high risk of wildfires, some shops removed disposable barbecues from shelves.

In Surrey and Yorkshire, the Environment Agency has had to move fish from rivers which are drying up to and deeper and cooler waters.

In 1976 and 2018 the UK had severe droughts lasting months, caused by dry springs and very hot summers.

The government took emergency powers under the 176 Drought Act to turn off domestic and industrial water supplies.

In 2018, the drought led to crop failures, which raised food prices. Multiple water restrictions were imposed.

The National Infrastructure Commission - which advises the UK government - says there could be more droughts in future because of population growth and climate change.

It has called for people to use less water and for water companies to let less of it leak away.

It's thought up to three billion litres of water are lost in the UK every day.
