Priority investment irrigation methodology in depressed rural areas

The infrastructure for small irrigation systems demands costly investment which may become increased as many social and technical aspects related to the concerns of regions susceptible to investment remain unknown. The lack of both information and a social network supporting planning and design tasks constitute factors affecting many irrigation projects, consigning them to failure. Some indicators were prepared for constructing an irrigation system in the north of the Cauca department in Colombia which, in turn, led to determining investment priorities and facilitated decisionmaking. The indicators guaranteed that the construction would benefit the greatest number of users, assuring wider irrigation coverage. The project lasted forty-two months; the basic irrigation system was designed and constructed during this time, alternating direct reception via surface water sources and digging wells to use groundwater. Investment costs were lower than estimated FAO reference ones
