Agro-well and pump diffusion in the dry zone of Sri Lanka: Past trends, present status and future prospects

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...

Vermillion, Douglas Lynn; Samad, Madar; Pusposutardjo, Suprodjo; Arif, Sigit S.; Rochdyanto, Saifal.

Examines the extent to which the Government of Indonesia's aspirations were realized through turnover program adopted in 1987. The impacts of management turnover on irrigation management and irrigated agriculture in selected systems in West and Central Java are analyzed. This study is part of a comparative research program to examine the impacts of irrigation management transfer in several countries using a common methodology.

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...

Abernethy, Charles L.; Sally, Hilmy; Lonsway, Kurt; Maman, Chegou.

Presents the results of case-studies of the functioning of four pump-based irrigation systems in the Niger River Valley. Prospects for sustainability are analyzed, especially in the light of the government's policy of promoting irrigator organizations to take over responsibilities for operation and maintenance.

Fruit yield and quality of Palmer mango trees under different irrigation systems.

Impact assessment of rehabilitation intervention in the Gal Oya Left Bank

SIMOES, W. L.; MOUCO, M. A. do C.; ANDRADE, V. P. M. de; BEZERRA, P. P.; COELHO, E. F..

Mango production has been having a great economical expression in the Brazilian agriculture. However, the economic crisis and increased competitiveness of the international market required improvements in the crop efficiency for its sustainability. In this context, the objective of this work was to evaluate the effect of different irrigation system on the physiology and fruit yield and quality of Palmer mango trees in the semiarid conditions of the Lower Middle São Francisco Valley, Brazil. The experiment was carried out at the Agranvil Farm, in Petrolina, state of Pernambuco, Brazil, with harvests in July 2013 and October 2014. A randomized block statistical design was used, with four treatments replicated in 5 blocks, during two production cycles. The...
