  1. Earth Observation technologies to improve Irrigation Advisory Services Anne M. Jochum, Alfonso Calera & Andrés Cuesta Instituto de Desarrollo Regional. Albacete Universidad de Castilla-La Mancha

  2. DEMonstrationof EarthobservationTechnologiesin Routineirrigation advisory services D E M E T E R Project co-funded by the European Commission EVG1-CT-2002-00078

  3. D E M E T E R • Objectives • To improve the efficiency in the use of water for irrigation • To assess, develop, and demonstrate how • Øto improve the performance and cost-effectiveness • of IAS by incorporating EO techniques in daily operations; • Øto make information easily available to IAS and farmers • (end-users) by integrating IT in the information generation • and distribution. • Increase crop water productivity

  4. more crops more jobs per drop Water productivity Rural development Sustainable Agriculture DEMonstration of Earth observation TEchnologies in Routine irrigation advisory services

  6. Irrigation Advisory Service Albacete Current procedure: Outputs Evapotranspiration of crops ETo ETc Kc Agroclimatic Station Phenology crops Measurements

  7. Irrigation Advisory Service Albacete Current procedure: • Irrigation Communities • Local press • Local TV • Answer phone • Fax • Visits to private sites • Internet: www.itap.es The distribution of data to the user

  8. Earth Observation Module Weather and climate information: rainfall (previous dates predictions), other data Kc Advanced products Remote Sensing Information Technology Field work End user (farmer) Kc Crop Water Requirement (FAO procedure) Agrometeorological stations ETo Space and IT assisted Irrigation Advisory Service (e-SAIAS) DEMETER Information Technology Module Irrigation Advisory Service (Current situation) DEMonstration of Earth observation TEchnologies in Routine irrigation advisory services

  9. Specification of DEMETER products DEMonstration of Earth observation TEchnologies in Routine irrigation advisory services

  10. Space-time resolution Spatial Resolution 20 - 30 m sufficient to resolve plots of 10000 m2 4 - 6 days weekly irrigation scheduling cycles Temporal Resolution DEMonstration of Earth observation TEchnologies in Routine irrigation advisory services

  11. EO virtual satellite constellation full set of high-resolution satellites + inter-satellite cross-calibration procedure (Martínez and Calera, 2001)

  43. Conclusions • EO adds spatial dimension; • IT adds interaction with / participation of all users; • EO mature & directly matches FAO procedure; • EO virtual constellation solves time-space constraint; • pre-operational campaign shows potential of real-time operations.
