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

2 D E M E T E R D E M E T E R Project co-funded by the European Commission EVG1-CT DEM E TeR DEMonstration of Earth observation Technologies in Routine irrigation advisory services

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 to improve the performance and cost-effectiveness to improve the performance and cost-effectiveness of IAS by incorporating EO techniques in daily operations of IAS by incorporating EO techniques in daily operations; to make information easily available to IAS and farmers to make information easily available to IAS and farmers (end-users) by integrating IT in the information generation and distribution.
