Agricultural Water Demand in Guadalquivir River (2005 Value vs. 2015 Scenario) AgEcon
Mesa-Jurado, Maria A.; Berbel, Julio; Piston, Juan Maximo.
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...

Evolución de la productividad del agua en la Cuenca del Guadalquivir 1989-2005 AgEcon
Carrasco, Jose Manuel; Piston, Juan Maximo; Berbel, Julio.
Para entender el desarrollo de la agricultura de riego es necesario estudiar la evolución de la productividad del agua en los cultivos de regadío. Este trabajo analiza la evolución de este indicador en los años 1989 y 2005 en la Cuenca del Guadalquivir. Para ello, se han utilizado datos estadísticos que, primero, han sido tratados a nivel comarcal y de cultivo y, posteriormente, se han agregado hasta obtener un valor global para toda la cuenca. Del conjunto de los resultados se deduce un valor de la productividad aparente del agua de aproximadamente un 0,5 €/m3 para el año 2005 y un incremento de un 327% respecto al año 1989.

Irrigation Water Value Scenarios for 2015: Application to Guadalquivir River AgEcon
Mesa-Jurado, Maria A.; Piston, Juan Maximo; Giannoccaro, Giacomo; Berbel, Julio.
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 also described in detail including Reformed CAP and biomass demand. It is applied at the basin level for the Guadalquivir River in 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 ‘comarcas’; in each of them 24 possible crops are selected with specific ‘comarca’ data bases. The 2015 scenario studies the present level of water use and value, and makes an analysis for 2015.This model allows the knowledge of water value and irrigated agriculture at ‘comarca’...
