Research Interests: Land surface processes and remote sensing with emphasis on hydrology and water management. In recent years he has coordinated a EU research project Hydrological Determinants of Agricultural Production in South America: the contribution of numerical crop growth models and remote sensing. He is currently the coordinator of a EU network dealing with Climate Impact on Water and Drylands Agriculture (CLIWARDA) This is a worldwide network with participants from China, India, Argentina, Egypt and Niger besides UK, Italy and The Netherlands. Past investigations include studies of groundwater hydrology in the deserts of Libya and Egypt, the use of advanced Earth Observation sensors systems to improve the performance of atmospheric models and irrigation water management in several countries.
