Agro-well and pump diffusion in the dry zone of Sri Lanka: Past trends, present status and future prospects AgEcon
Kikuchi, Masao; Weligamage, Parakrama; Barker, Randolph; Samad, Madar; Kono, Hiroichi; Somaratne, H.M..
The use of shallow wells, equipped with small pumps, to lift groundwater has spread rapidly in many agricultural regions of tropical monsoonal Asia. In Sri Lanka, the rapid and pervasive invasion of agro-wells and pumps drew the attention of policymakers and researchers, but many questions were left unanswered due to lack of research in the area. This study aims to fill this gap in knowledge, based on observations and data obtained in field surveys conducted in major and minor irrigation schemes in the dry zone of Sri Lanka. This report gives the key findings of this study into the pattern, extent and causes of the spread and use of agro-wells and pumps in traditional villages and irrigated settlement schemes. It investigates farmer investments in...

Análisis técnico y económico del diseño de un sistema de riego a hidrante parcelario utilizando dos métodos, por turnos y con la técnica de Clement. Colegio de Postgraduados
Espinosa Espinosa, Bartolomé.
El uso óptimo y sostenible de los recursos hídricos disponibles para riego requiere que las instalaciones usadas para irrigar permitan administrar el agua con las estrategias de manejo adecuadas a cada situación. Este aspecto, al que en ocasiones no se le ha dado suficiente importancia, resulta hoy en día absolutamente imprescindible si se quieren rentabilizar las inversiones requeridas en infraestructura, estando condicionado por los cultivos que se adopten en la zona regable, así como por la evolución de las políticas y mercados agrícolas. Por ello, el presente estudio tuvo como objetivo realizar un análisis técnico y económico del diseño de un sistema de riego a hidrante parcelario empleando dos métodos de diseño, el método por Turnos y el método de...
