Agro-hydrological Management

Agro-hydrological Management

Everyone knows that water is becoming an increasingly scarce resource. This causes frequent confrontations between the different parties concerned (environmental organs, tourism, agriculture…). Agriculture is the greatest consumer of fresh water; thus it is necessary to know the exact water needs of crops (in mm/ha) throughout the entire crop cycle as well as their position within the territory in order to optimize water management.

The widespread availability of new satellite-borne sensors in combination with physio-mathematical models have facilitated the development of data processing techniques as well as the integration of more efficient irrigation systems. The use of satellite images along with the Geographic Information System (GIS) present important advantages in comparison with traditional methods given that it is possible to obtain images of huge swaths of land in just one pass. Other advantages include a low cost per unit of surface area, regular updating and multispectral information.
