The water we eat-heavy losses caused by irrigated crops

Agriculture is placing an increasing burden on European water resources, which may lead to the risk of water shortages and damage to the ecosystem. In order to achieve the goal of sustainable water use, farmers need to be given appropriate price incentives, guidance and assistance.

Food is intrinsically linked to human well-being.Beyond
The importance of good nutrition for maintaining health
Health and eating pleasure, agricultural production plays an important role
It is very important and can be used as a means of personal sustenance and economic development
Broadly.

But food production also consumes a lot of water,
This is an equally important resource.Agriculture has an impact
There is 24% of water withdrawal in Europe, although it does not look like a

The share is usually only one-third.

In addition, agricultural water consumption has a distribution

It accounts for more than 80% of the water extracted.Extract water

The lowest available state causes more damage.

The most recent EEA report, Water resources across Europe-facing water

The results are obvious in many parts of Southern Europe.
