  abstract = {{In a context of increased demand for food and of climate change, the
water consumptions associated with the agricultural practice of
irrigation focuses attention. In order to analyze the global influence
of irrigation on the water cycle, the land surface model ORCHIDEE is
coupled to the GCM LMDZ to simulate the impact of irrigation on climate.
A 30-year simulation which takes into account irrigation is compared
with a simulation which does not. Differences are usually not
significant on average over all land surfaces but hydrological variables
are significantly affected by irrigation over some of the main irrigated
river basins. Significant impacts over the Mississippi river basin are
shown to be contrasted between eastern and western regions. An increase
in summer precipitation is simulated over the arid western region in
association with enhanced evapotranspiration whereas a decrease in
precipitation occurs over the wet eastern part of the basin. Over the
Indian peninsula where irrigation is high during winter and spring, a
delay of 6 days is found for the mean monsoon onset date when irrigation
is activated, leading to a significant decrease in precipitation during
May to July. Moreover, the higher decrease occurs in June when the water
requirements by crops are maximum, exacerbating water scarcity in this
region. A significant cooling of the land surfaces occurs during the
period of high irrigation leading to a decrease of the land-sea heat
contrast in June, which delays the monsoon onset.
