In the Gash Delta of Eastern Sudan, spate irrigation (flood-recession farming) contributes substantially to rural livelihoods by providing better yields than rainfed dryland farming. However, spate irrigation farmers are challenged by the unpredictability of flooding. In recent decades, the number of farmers practicing spate irrigation has decreased, due to varying rainfall intensity and frequency, insufficient infrastructure and farmers’ limited capacity to manage such variations.

The effect of irrigation service delivery and training in agronomy on crop choice in Tajikistan

Journal Articles & Books
November, 2018

The aim of this paper is to analyze the effect of irrigation delivery services and agricultural extension services on crop choice in southern Tajikistan. This analysis is motivated by the government’s recent efforts to address the country’s severe malnutrition problem by supporting changes in irrigation service delivery and agronomy to increase diversity in agricultural production and consumption, in an environment where the cultivation of cotton had, until recently, been mandatory.

Estimating technical and irrigation water productivities in rice production in Tamil Nadu, India

Journal Articles & Books
December, 2017

The overall measure of farm-level technical efficiency is generally used to derive recommendations for the use of individual inputs. In this paper, joint estimation is made of technical and individual input-use (e.g. irrigation water productivity) efficiencies. This indicates that overall technical efficiency is not an indication of the efficiency level of all the individual inputs used. This is because the efficiency of individual inputs may vary and suggests that greater effort should be made to improve such efficiencies in comparison with overall technical efficiency.

Below the radar: the boom of groundwater use in the central part of the Nile Delta in Egypt

Egypt

The Nile Delta of Egypt is known for its large irrigated area supplied with water diverted from the Nile River, with a limited use of groundwater, largely for domestic and industrial use. Official statistics for the whole delta indicate that there are a few thousand individual wells used for agriculture by a population of over 2 million farmers. This study, however, shows that a phenomenon of groundwater development for irrigation has been unfolding over the last few years, largely below the radar of managers and researchers.

Farmer participatory research in cassava soil management and varietal dissemination in Vietnam

Journal Articles & Books
December, 1998

Farmer Participatory Research (FPR) in Vietnam has been carried out since 1994 in collaboration with CIAT, with the objective of improving the adoption of soil conservation practices in cassava fields. Two villages in Pho Yen district, Bac Thai province; one in Thanh Hoa district, Vinh Phu province; and one in Luong Son district of Hoa Binh province were selected as pilot sites for implementing the FPR methodology.

As solar panels become more a ordable, solar photovoltaic (PV) pumps have been identi ed as a high potential water lifting technology to meet the growing irrigation demand in sub-Saharan Africa (SSA). However, little is known aboutthegeo-spatial potentialofsolarbasedPVpumpingforirrigationtakinginto accountnotonlysolar radiation but also the availability of water resources and linkage to markets. This study developed a suitability framework using multi-criteria analysis in an open source GIS environment and tested it in the case of Ethiopia.
