Guadalquivir: agriculture
Agricultural systems
20
Irrigation to increase production and profit New crops are available Higher yields of crops irrigated versus rain fed
Irrigation to reduce risk More stable production (yields stabilized) More crops available (risk diversification)
Irrigation as solution
Move water from:• Winter to summer• Wet to dry years• Mountains to valleys• Less to highly productive areas

Concluding remarks
Use of WAfor cost recovery analysis
These figures can be compiled from the hybrid supply anduse tables.
Final points A good opportunity to study
Impact of agriculture modernization (water saving, cost increase)
Impact of deficit irrigation Large mediterranean basin Good available data (althought in different format)
Possible integration of Water Accounts in Basin Hydrological Plan 2015
Open to suggestions Thank you for the opportunity
