Requerimiento hidrico y areas sujetas a riego en Espinar: estimaciones

Abstract

Espinar constitutes one of the most important scenarios in the livestock, agricultural, fish farming and tourism aspects; the large Andean plateau has natural pastures and soils rich in humus, which are an example of the potential use that could be given to these natural resources. The Andean prairie in Espinar is equivalent to 300,000 hectares, these could be more productive if irrigation technologies, improvement of pastures and livestock, use of water in fish farming, mainly trout farming, were incorporated. The main collector is the Apurimac River and its tributaries that cross the territory with excellent flows in the rainy season and show critical flows in the dry season and lead through its channels the water resource that could be used for socio-economic and environmental take-off of the inhabitants of Espinar province that belongs to the Cusco region. Estimates of the demand for water resources have been made using conventional methodologies for the various uses of water, linked to pasture irrigation, employment of South American camelidaes, sheep, cattle and trout farming; the calculations have been determined based on primary information and the experience developed in recent years in the field of study, which refers to the area of direct influence of the Apurimac River. The estimates are linked to the uses of water for human consumption, irrigation in agriculture and pastures, livestock activities, fish farming and, ecological flow; being the calculated water demand of 48.8 m3 / s required to irrigate 45,421 ha.
