Key policy question: Is the abstraction rate of water sustainable?

Key messages

Over the last 10-17 years the Water Exploitation Index (WEI) decreased in 24 EEA countries (Fig.1), as a result of water saving and water efficiency measures.
Total water abstraction decreased about 12 %, but one fifth  of Europe's population still lives in water-stressed countries (approx. 113 million inhabitants).

Water exploitation index (WEI).

Note: Annual total water abstraction as a percentage of available long-term freshwater resources around 1990 (WEI-90) compared to latest year available (1998–2007) (WEI-Latest Year).

Key assessment

The warning threshold for the water exploitation index (WEI), which distinguishes a non-stressed from a stressed region, is around 20 % (Raskin et al. 1997). Severe water stress can occur where the WEI exceeds 40 %, indicating unsustainable water use.

In Europe there are five countries that can be considered water-stressed based on the Eurostat data available for the period 1998-2007 (Cyprus, Belgium, Spain, Italy and Malta), representing about 19.5% of Europe's population. Based on the 2007 available data Cyprus (64%) and Belgium (32%) have the highest WEI. However, it is necessary to take into account the high water abstraction for non-consumptive uses (cooling water) in Belgium which results in its high WEI. Most of the water abstracted in the remaining three water-stressed countries (Spain, Italy and Malta) is for consumptive uses (especially irrigation) and there is therefore higher pressure on water resources in these three countries.


The WEI decreased in 24 countries over the last 10-17 years, representing a decrease about 12 % in total water abstraction. Most of the decrease occurred in the eastern countries, as a result of the decline in abstraction in most economic sectors. This trend was the result of institutional and economic changes. However, five countries (The Netherlands, Greece, Finland, Slovenia and Turkey) increased their WEI during the period 1990 to 2007 because of the increase in total water abstraction. The WEI has also increased in Cyprus from 1998 to 2007 (lack of data do not allow comparison to the pre-1998 period). It should be noted that since WEI is calculated on a country level basis, spatial variability can not be depicted and a low WEI in one part of a country can leverage a high WEI in another part. For example, Pinios RBD in Greece is severely water stressed, nevertheless this is evened out at the country level WEI. Similarly the regional WEI in Portugal is extremely variable per river basin (Sado RB 132%, Leca RB 82%, Minho RB 1%, Lima RB 5%) but at country level is averaged at 15%.

Specific assessment

All economic sectors need water for their development. Agriculture, industry and most forms of energy production are not possible if water is not available. In Europe as a whole, 37 % of freshwater abstraction is for cooling in energy production, followed by agriculture, 33 %; public water supply, 20 %; and industry, 10 % (Fig. 2). In southern Europe agriculture accounts for more than half of total national abstraction, rising to more than 80 % in some countries, while in Western Europe more than half of water abstracted is used for cooling in energy production

These sectors differ significantly in their consumptive use of water. Almost all water used as cooling water in energy production is returned. In contrast, the consumption of water through crop growth and evaporation typically means that only about 30 % of the amount abstracted for agriculture is returned.

 
Water abstraction for irrigation/agriculture (Fig.3).  Since the early 1990s there has been an 88 % decrease in water abstraction for irrigation in Eastern Europe. This was driven mainly by the decline of agriculture in Bulgaria and Romania during the period of economic transition, with poor maintenance and abandonment of irrigation systems. In the remaining eastern EU countries, the total irrigable area has declined by about 20 %. Water abstraction for irrigation in Western Europe is very low compared with southern countries but rises in years with dry summers.

Water abstraction for irrigation decreased by about 2 % in Southern Europe other than Turkey, where it increased by up to 36 % from the 1990 level. In Southern Europe there is a tendency to use irrigation water more efficiently with a higher proportion of the area using drip irrigation. Also, the use of recycled water in these areas has increased (EEA 2009). Although the main source of irrigation water is surface water, unregulated/illegal water abstraction, mainly from groundwater, need to be added to the high figures for water abstraction for irrigation in many Southern European countries (EEA, 2009).

Abstraction for public water supply (Fig 4).  A range of factors influence public water demand, including population and household size, tourism, income, technology, and lifestyle. Public water demand in Eastern Europe has declined by 40% since the early 1990s as a result of higher water prices and the economic downturn. A similar but less marked reduction in demand is apparent in Western Europe over recent years, driven by changes in awareness and behaviour and increases in water prices. In Southern Europe domestic use has increased by 12% and Turkey up to 59%.

Water abstractions for manufacturing industry (Fig 5).  The abstraction of water for industrial use has decreased over the past 20 years, 10% reduction in western (central & northern) countries, 40% reduction in southern countries and up to 82% reduction in eastern countries. In Turkey the reduction reaches 30%. The decrease is partly because of the general decline in water-intensive heavy industry but also because of increases in the efficiency of water use.

Water abstraction for cooling in energy production (Fig 6) accounts for 37 % of the total water abstraction in Europe. In some countries such as Germany, France, and Poland more than half of the total abstracted water is for energy production. Energy cooling water abstractions in Europe have decreased overall by 10 % over the last 10-15 years. Abstraction for cooling water has also decreased, due mainly to the implementation of advanced cooling technologies that require less water.
