Without better oversight and water pricing strategies, scarcity could grow in European countries and even threaten the future of groundwater supplies in some regions, the analyses say.
Improving water efficiency is a central issue in the EU executive’s current review of the Water Framework Directive, with recommendations on improving implementation and enforcement expected by November.
The Commission has also proposed new efficiency and conservation measures in its draft of the 2014-2020 Common Agricultural Policy (CAP).
One such proposal calls for requiring that new irrigation systems achieve a minimum 25% of water savings in order to qualify for EU funding, replacing the current open-ended compensation scheme.
The European Commission's agriculture directorate "has proposed that they are only funding irrigation projects where at least 25% of the water is saved,” said Thomas Dworak, a Vienna-based consultant and contributor to one recent analysis of agricultural water use.
"And now member states are against it because they would lose a lot of subsidies.”
Sources in both the Commission and European Parliament confirmed that the measure faces an uphill battle in the co-decision process involving EU national leaders and the Parliament.
The report on water use in agriculture – and a separate study prepared for the Commission’s environment directorate – underscore challenges across Europe but especially in groundwater use.
Sarah Bogaert, a lead author one study, says pricing is not an easy issue but “it’s important that you give the right signals” to farmers and other consumers.
In some southern regions of the EU facing the most dire water challenges, “there is just no price for abstracting water by the farmer … they do not pay any environmental costs of abstraction.”
The study was prepared by the ARCADIS consultancy for the European Commission. It cites the need for more comprehensive metering, monitoring and enforcement of water use and calls for a “paradigm shift” in the CAP and Cohesion Policy to promote sustainable consumption.
Globally, agriculture accounts for 70% of freshwater consumption while in the EU, the average is 24%, according to UN and EU figures. But in several southern countries, the figure approaches 90% - leading to rationing of supplies in the driest months.
Desperation also forces farmers to turn to from dry streams to groundwater, risking gradual depletion.
Despite the challenges, farmers and national leaders are not standing still.
The ARCADIS report cites awareness efforts in Cyprus, France and Spain – where several regions face scarcity – as making strides in reducing irrigation waste.
Despite apparent opposition to setting efficiency standards for new irrigation systems, Romania does just that - farmers are required to achieve a minimum 10% in water savings to get rural development funding for new watering systems.
Malta is using satellites to monitor illegal boreholes on farms.
“It’s a good way of enforcing legislation because they say, ‘OK we have a map of where the registered boreholes are, so we just take a photo put that over the map, and every green spot that doesn’t match with a registered borehole, we know it’s illegal,” said Dworak, director of Fresh Thoughts Consulting and a contributor to the ARCADIS report.
The report also recommends steps to improve metering and put agricultural water pricing more in line with use.
But dearer water prices come at a risk. A separate prepared for the Commission warns that “illegal abstraction may increase with higher prices and/or monitoring,” with farmers turning from public supplies to boreholes or channels off streams.
The report shows there are 50,000 boreholes in Cyprus, many illegal, compounding the country’s declining groundwater reserves.
