La huella hídrica como indicador del uso eficiente del agua en la producción de rosas, leche y huertos agroecológicos en la Comunidad de Pesillo del cantón Cayambe

Abstract

This resesrch was carried out at Pesillo´s community, Olmedo parish in Cayambe Canton, through evaluation of the water footprint it was determined the relationship that exists between production systems agricultural and the water efficiency. In order to analize the water distribution, taking into account the demand that occurs within of production systems, due to as it is generated a social issue related to unknowledge of the efficient use of irrigation water. That’s why indicators was identify to allow know which of the production systems are more efficient: pasture, agro ecological gardens or roses. The study was performed in 5 APUs (Agri Production Unit), in wich surveys was made providing technical datam overhead costs, use of chemical inputs and others. Technical data was obtained using the pluviometry irrigation method (aspersion and drip); DBO, DQO, Conductivity, pH, Nitrate, Nitrites y Total Phosphorus as physico- chemical parameters analysis was determined collecting the water sample in the hydrant. In order to determine each water plot needs, Cropwat 8.0 software was used. Results shows water need gets 18, 23 mm/day in pasture, 18, 08 mm/day in roses and orchard with a 17, 93 mm/day. Application efficiency in roses 73, 37%; pasture 56, 75%; y orchard 45, 53%. For water consumption costs analysis was calculated an excel sheet was made where an economic balance was obtained. Investment and operation costs of are directly proportional to the income generated, been the highest percentage roses, followed by pastures and finally orchards. While in physico- chemical parameters, results shows that that irrigation water is in optimal condition for use under current regulations established by law.
