| Zusammenfassung |
In Europe, public water withdrawals make up on average 30% and in some
cases up to 60% of total water withdrawals. These withdrawals are
becoming increasingly important with growing population density; hence there
is a need to understand the spatial and temporal trends involved.
Pan-European public/municipal water withdrawals and consumption were mapped
for 2006 and forecasted for 2030. Population and tourism density were
assumed to be the main driving factors for withdrawals. Country-level
statistics on public water withdrawals were disaggregated to a combined
population and tourism density map (the "user" density map) computed for
2006. The methodology was validated using actual regional withdrawal
statistics from France for 2006. The total absolute error (TAE) calculated
was proven to be reduced by taking into account the tourism density in
addition to the population density.
In order to forecast the map to 2030 we considered a reference scenario
where per capita withdrawals were kept constant in time. Although there are
large variations from region to region, this resulted in a European average
increase of water withdrawals of 16%. If we extrapolate the average
reduction in per capita withdrawals seen between 2000 and 2008, we forecast
a reduction in average total water withdrawals of 4%. Considering a
scenario where all countries converge to an optimal water use efficiency, we
see an average decrease of 28%. |
