Descripción
This paper reviews the application of a
scenario for the 2015 agricultural policy and markets for
the irrigated agriculture in Europe. Scenarios for
irrigated agriculture 2015 are described in detail
including Reformed CAP and how biofuel impacts
demand. A model for irrigation water demand is applied
at the basin level for the Guadalquivir River (Southern
Spain). The methodology is based upon residual value of
water and it combines budget and farm analysis at
municipality level, with the Guadalquivir basin divided
at 50 counties where 24 possible crops are selected and
adapted specifically to each county yield and costs. The
result is a comparative analysis between actual level of
water use and value, and 2015 scenario at county level
and later aggregated at basin level.
