German economy vulnerable to water scarcity — WWF
Water
is scarce but it continues to be wasted excessively in many industrial
states, warns a new study by the World Wide Fund for Nature, predicting
that a global conflict over water resources could bring billions in
losses for the German market, EurActiv Germany reports.
Euractiv.com reported that
tomatoes from Spain, textiles from India, metals from South Africa,
roses from Kenya; every year, Germany imports massive amounts of goods
from around the world that would not be available without considerable
water resources.
But water is becoming an increasingly
scarce global resource. In many countries, it has become more and more
difficult to supply the population with adequate drinking water and
irrigation for crops.
Besides export-reliant countries with
critical water resources, the effects of the shortage can be devastating
for others as well.
According to the World Wide Fund for
Nature, the worldwide water shortage will also impact industrialised
European countries like Germany.
If German imports are cut off due to
water shortages in producer states, German companies would be hard hit,
said a WWF study released on Wednesday (27 August).
Philip Wagnitz, one of the authors of the
study, said many German economic sectors are both responsible for and
affected by the international water crisis, from the food sector to the
auto and fashion industries.
In Germany itself, the Federal
Environment Agency has indicated sufficient water resources. The
country’s annual water supply is estimated around 188 billion cubic
metres.
But Wagnitz explained that the third
largest importing country in the world is extremely dependent on foreign
goods, which often require large quantities of water during production.
WWF reported that annual cotton and
textile imports from Pakistan to Germany, require twice as much water as
the volume of Germany’s fifth largest lake, the Starnberger See, which
holds three billion cubic metres of water.
Almost 9,000 litres of water are needed
to produce one kilogram of cotton in Pakistan, primarily drawn from
rivers in eastern parts of the country.
But even so, only around one third of the
water even reaches the fields, the WWF study indicated. The rest
evaporates or leaks out along the way in decrepit irrigation canals. As a
result, many areas pump the water they need directly from the
groundwater.
The effects of this type of water
abstraction can be observed in areas such as the Aral Sea in Uzbekistan,
WWF warned. There, the sea’s tributaries have been dried up by cotton
production, causing the sea to shrink by almost 90 per cent.
In extreme cases, growing water risks
being brought on by these developments could create billions in losses
for German companies, Wagnitz said. The affected firms would have to
deal with image problems and site closures, he stated.
Still, many do not even realise their own
exposure to hidden water scarcity risks, the WWF expert warned. They
will only become aware of the issue once shortages start to materialise,
Wagnitz explained.
This is precisely what happened in India
recently, he said, when Coca-Cola was forced to close one of its
bottling sites. Farmers in the area complained that water they needed
was being wasted on soft drink production.
Wagnitz mentioned the apparel
manufacturer H&M as another example: When cotton harvests in many
parts of Pakistan were desolated by monsoon rains four years ago, prices
for raw materials grew painfully high. In the worst case, the WWF
expert said, flooding or droughts could cause billions in losses on the
local market.
And scarcities in local water resources are no longer a concern reserved for developing countries and desert regions.
A study by the European Environment
Agency in southern Europe, where water shortages are increasingly
critical, showed 80 per cent of water is used for agriculture.
In Spain, WWF warned that the threat of
drought is particularly high, exacerbated by illegal irrigation. In 2013
alone, Germany imported about 180,000 tons of tomatoes valued at €250 m
from Spain. Because the groundwater can no longer supply enough to
irrigate fields, farmers have turned to desalinated seawater for several
years now.
Nevertheless, worldwide water usage is on
the rise. According to estimates in the latest UN World Water
Development Report from 2012, the shortage threatens all Millennium
Development Goals agreed on by the UN General Assembly in 2000.
Growing demand for water can mostly be
traced to climate change and an increasing demand for food in a rapidly
urbanising world, according to UNESCO secretary general Irina Bokova and
the head of UN Water Michel Jarraud.
