  1. System of Water Accounting in the Guadalquivir River Basin Universidad de Córdoba. Julio Berbel K.O meeting of the 2013 Halting Desertification in Europe Pilot projects Brussels 5 Feb.2014

  2. Systems of water accounting in the Guadalquivir River Basin • SIWAG No. 2013/13 • Partners: • Universidad de Córdoba • EVREN (Evaluacion de recursosnaturales) • Period: 12 months 1/feb/2014 to 30/jan/2015 • K.O internalmeeting: • 27/01/2014 • UCO/EVREN/ Confederación Hª Guadalquivir (Sevilla) • Agreement • To cooperate throught the project • Tointegrateresults in Hydrological Plan (revisionduefor 2015)

  3. Guadalquivir: general

  4. Area, population, economy

  5. Thebasin The basin has a Mediterranean climate with a heterogeneous precipitation distribution. The annual average temperature is 16.8C,

  6. Guadalquivir riverbasin • The Guadalquivir River is the longest river in southern Spain (around 650 km) • Population of 4,107,598 inhabitants • Main cities are: Seville, Cordoba, Granada • Covers an area of 57,527 km2 • Main land uses are: • Forestry: 49.1% • agriculture : 47.2% • urban areas: 1.9% • Wetlands: 1.8% • Irrigation 850.00 ha • (25% land, 70% value)

  7. Rain in a Mediterraneanriver (Guadalquivir) 573mm 5 Annual precipitation averages at 573 mm (range between 260 mm and 983 mm ) * 13 en sequia

  8. Dryyears Guadalquivir 1942-2012, yearsbelow 15% of average • Libro Blanco del Agua, mostseveredrought in 200 years are: • Oct.1941 a sept.1945, • Oct.1979 a sept.1983 • Oct.1990 a sept.1995 • In XXI centuryfromOct 2005 tosept 2008. 79-83 90-95 04-09 Drought (>3 years) Desde 1977 10 años (29%) precedidos por uno o mas años secos

  9. Period of rain in models (Guadalquivir)

  10. Guadalquivir riverbasin figures • Average renewable resources • 7,043 (arithmetic mean) and 5,078 GL/year (median), • Minimum 372 GL/year, Maximum of 15,180 GL/year • 65 dams storage capacity 8,500 GL

  11. Guadalquivir river average monthly flow

  12. Origin of water Source: CHG f(2010)

  13. Unregulatedriver Averagewaterservedis 67%of waterrights

  14. Use of water by sectors

  15. Economicanalysis (preliminary)

  19. Guadalquivir: agriculture

  20. Agriculturalsystems

  21. Irrigation as solution • 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) • Move water from: • Winter to summer • Wet to dry years • Mountains to valleys • Less to highly productive areas GuadalquvirMonthly rain and ETP (mm)

  33. Impact of irrigationmodernization Berbel et al (unpublished) Analysis of studies on the rebound effect of water saving measures

  34. Concludingremarks

  35. Use of WAforcostrecoveryanalysis These figures can be compiled from the hybrid supply and use tables.

  36. Final points • A goodopportunitytostudy • Impact of agriculturemodernization (watersaving, costincrease) • Impact of deficitirrigation • Largemediterraneanbasin • Goodavailable data (althought in differentformat) • Possibleintegration of WaterAccounts in BasinHydrological Plan 2015 • Open tosuggestions • Thankyoufortheopportunity
