Water scarcity has become a worldwide phenomenon, with acute problems at some localities. The objective of the Hortimed RTD project was to develop a context sensitive strategy for managing irrigation and nutrient supply to protected cropscrops and hydroponics, under constraint conditions on the quantity and quality of the water supply. The economical (quality and quantity of crop yield/ the producer side) and the ecological (sustainability, contamination risks of water table, and healthy vegetables/ the consumer side) factors, affecting the strategic and operational decisions, have been the focal points of the research.

The research activities of the project have advanced our knowledge on:

  • biological information about detailed plants’ responses (i.e. nutrient uptake models, yield response to salinity etc),

  • technical developments on how to precisely furnish such needs (cooperative root and shoot environment management), as well as

  • complex optimization algorithms to utilize such information and provide best tradeoff solutions regarding the consumer quality requirements, the sustainability of the environment and the income of the grower, and all these in a very competitive world
