  1. Ador: A management software for irrigation districts I. Mantero R. Salvador E. Playán J. Cavero S. Lecina

  2. Today’s news by WWF (J. Pittock) • “Preserving rivers and wetlands is an essential part of National Security, health and economic development.Intense research is needed to use water more efficiently in crops and other activities, so that only the required water is used“* • Flaw: at the basin level the key aspect is evapotranspiration, directly related to crop yield • At the irrigation project level: living with limited water resources requires adjusting diversions to requirements • At both levels, all water used for irrigation must be accounted for in a certified, traceable system… *) El País digital, March 20, 2007. www.elpais.com, translated from Spanish

  3. Two paths to improve irrigation efficiency: • Structures • 99 % of the Spanish National Irrigation Plan • Management • 1 % of the Spanish National Irrigation Plan (26 M€) • Advantages: • Bottom - up • Slow and endogenous • Much cheaper (€/m3 of conserved water)

  4. Irrigation management principles • Transparency • Participation • Traceability • Effectiveness • Standarization • Certification

  5. Derived from research projects • Started research in 1997 • Researchers from: • Estación Experimental Aula Dei (CSIC) • Centro de Investigación y Tecnología Agroalimentaria (DGA) • Objective: • A software to support daily water management activities in irrigation districts • Regardless of type of water distribution, irrigation system or quality of management. • Support: • Research funds, • Government of Aragón, • Irrigation Districts (mainly “Riegos del Alto Aragón”)

  6. Derived from research projects • Cooperation between: • researchers, • farmers, • companies, • public administration and • water managers. • Half of the Aragonese irrigated land is managed with Ador (about 180,000 ha).

  7. Irrigation district administrative data

  8. Water pricing: a matrix

  9. Water users

  10. Cadastral plots and water uses

  11. Water uses

  12. A diagram of the irrigation network

  13. Secondary network elements

  14. Water management units

  15. Registering and allocating water orders

  16. Registering water meter readings

  17. Billing for general costs: by the hectare

  18. Billing for water use: by the m3

  19. The educational water bill

  20. Demand management: water restrictions

  21. Irrigation District “La Campaña”: histograms of water use per crop Corn

  22. GIS support: plot identification

  23. GIS support: searches and queries

  24. GIS support: supply lines and cadastral plots

  25. Irrigation Efficiency (%) Water use (m3/ha)

  26. Concluding remarks • Participative, endogenous effort • Institutional strengthening • Adjusting water input to crop water requirements • Increased management responsibilities • A long way to go • ... Decision makers are not (yet) believers in water management
