| Sumario: | Approximately 70% of all fresh water, one of the most important resources of the planet is used for agricultural activities, and the proportion is very similar in Ecuador. This is enough justification to any research or strategy in order to optimize the available irrigation water utilization. The research goal was to determine the efficiency of available irrigation water utilization per Agricultural Production Unit (UPA), in function of the irrigated area and the crop water requirements, in two locations of the Ecuadorian Range Area. The “Porotog” rural Irrigation Board, in Cangagua rural parish, at canton Cayambe, and “San Ramon” community, in Mulaló rural parish, at canton Latacunga. The field work included nine typical production systems, at the research locations. The results showed in Cangagua near of 95% of the UPA do not have enough irrigation water to supply the crop water requirements at the irrigated area. It means that these growers are underusing the irrigation water, because they irrigate more area than it can be irrigated with the available water. On the contrary, in Mulaló, the 85% of producers are overusing the irrigation water, because they have water in excess for the irrigated area. The main conclusion of the investigation refers: both the deficit and the excess of irrigation water in the UPA, that produce inefficiency in the consumption of this scarce resource, would be the result of equitable distribution of the water in the communities, which does not depend of technical factors like agricultural land available for irrigation, in order to assign the correct amounts of irrigation water. |
