Drought and Water Overuse in Europe
books, olive oil to vaccinations, all the goods and services that we rely on,
together with many of our daily activities, require a vital resource: water.
A new report by the European Environment Agency (EEA) confirms that in many
parts of
new approach to managing water resources.
The EEA report ‘Water resources across
scarcity and drought’ highlights that while southern
experience the greatest water scarcity problems, water stress is growing in
parts of the north too. Moreover, climate change will cause the severity and
frequency of droughts to increase in the future, exacerbating water stress,
especially during the summer months.
Excluding illegal water use,
freshwater annually, representing on average 5 300 m3 per capita, roughly
equivalent to two olympic swimming pools.
“We are living beyond our means when it comes to water. The short-term
solution to water scarcity has been to extract ever greater amounts of water
from our surface and groundwater assets. Overexploitation is not sustainable.
It has a heavy impact on the quality and quantity of the remaining water as
well as the ecosystems which depend on it,” said Professor
McGlade
amount of water that we are extracting and increase the efficiency of its
use.”
Key findings and recommendations
Shifting the management focus from increasing supply to minimising demand
needs to involve various different policies and practices:
- In all sectors, including agriculture, water should be priced according
to the volume used.
- Governments should implement drought management plans more extensively
and focus on risk rather than crisis management.
- Water-intensive bioenergy crops should be avoided in areas of water
scarcity.
- A combination of crop selection and irrigation methods can
substantially improve agricultural water efficiency if backed-up with
farmer advisory programmes. National and EU funds including the
European Union's Common Agricultural Policy can play an important role
in promoting efficient and sustainable water use in agriculture.
- Measures to raise public awareness, such as eco-labelling,
eco-certification, education programmes in schools, are essential to
realise sustainable water use.
- Leakage in public water supply systems must be addressed. In parts of
Europe, water loss via leakage can exceed 40 % of total supplies.
- Illegal abstraction of water, often for agricultural use, is widespread
in certain areas of Europe. Appropriate surveillance and a system of
fines or penalties should be put in place to address the issue.
- Authorities should create incentives for greater use of alternative
water supplies, such as treated wastewater, greywater, and 'harvested'
rainwater, to help reduce water stress.
Overview of water use in
In
24 % for agriculture, 21 % for public water supply and 11 % for industry.
However, these figures mask significant differences in sectoral water use
across the continent. In southern
for 60 % of the total water abstracted and reaches as much as 80 % in certain
areas.
Across
the total freshwater abstracted and are the predominant water source for
industry, energy and agriculture. By contrast, public water supply relies
mostly on groundwater due to its generally higher quality. Almost all water
used in energy production is returned to a water body, whereas most of the
water abstracted for agriculture is not.
Desalination has become a fast growing alternative to conventional
sources of water, particularly in water-stressed regions of
energy needs and the resulting brine must be taken into account, however,
when assessing desalination’s overall impact on the environment.
