abstract = {Irrigated agriculture is an important economic factor in
the rural parts of the metropolitan area of Hamburg. It is
commonly expected that climate change will reduce the
groundwater quantities available for field irrigation.
Against this background, the ratio of irrigation need and
groundwater recharge (IGR-ratio) is suggested as an
indicator to assess climate change impacts on the
vulnerability of groundwater resources towards
overexploitation by agricultural irrigation. The IGR-ratio
has been assessed based on the distributed water balance
model mGROWA, i.e. under consideration of the simulated
groundwater recharge levels and the field crop-specific
irrigation need of the commonly cultivated field crops. The
spatial IGR-ratio distribution determined for the observed
reference period 1971–2000 has shown that the delineated
vulnerable areas coincide with the regions for which high
irrigation quantities have been documented at present.
Additionally, the IGR-ratio depicts the areas in which
irrigation is currently still negligible, but in which the
introduction of irrigation into agricultural practice would
lead to an immediate overexploitation of the sustainably
available groundwater budget. The possible impact of future
climate on IGR-ratios was determined by using a model chain
of mGROWA and the regional climate models REMO and
WETTREG2010. The related ensemble simulations did not
provide a uniform tendency of possible future IGR-ratio
changes. Whereas the mGROWA–WETTREG2010 realisations
projected a very high increase in the IGR-ratios, the
mGROWA–REMO realisations did not show a pronounced trend
of increasing IGR-ratios. Therefore, considerable
uncertainties remain regarding the future bandwidth of
IGR-ratio changes.},
