Book (stand-alone)Improved on-farm participatory water management to reduce mining of groundwater in Yemen 2001
Also available in:
No results found.Water shortage is the most critical issue facing the Middle East and North Africa (MENA) Region and is likely to be exacerbated in the future because of high population growth and continuing decline in the renewable resources resulting from climate change, pollution and overdraft of groundwater. Despite this alarming situation, water management still faces major drawbacks as the largest share is used for agricultural production under traditional farming practices and low on-farm water use effici ency, resulting in very low output per unit of water use and consequently low economic returns from investments. However, because of the scarcity and unreliability of precipitation in the region, the improvement of irrigated farming systems still presents a high potential in the region and will undoubtedly continue to attract investment in the future, in comparison with rainfed systems. The present study is based on the outputs of several projects and sectoral studies, particularly a World Bank financed project aimed at introducing modern irrigation technological packages, in a participatory manner, under all major existing farming systems, as a measure to enhance water savings and improve farm income. -

On-farm trials for adapting and adopting good agricultural practices
2003Also available in:
No results found.Explore On-farm aims at improving sustainable production of rainfed wheat-based farming systems. It brings researchers, farmers and extension agents together, on-farm, to carry out guided and collaborative crop trials. The trials should lead to the identification and reduction of constraints to productivity and to the adaptation of general recommendations to local conditions. These guidelines work upon: increasing understanding of the local environment and how it, the crop and other yield-determ ining factors interact; improving management of cropping systems and thus, sustainable yield; and increasing crop diversification. They are not a set of static rules; on the contrary, they encourage modifications in order to address local needs and circumstances after a cycle of learning, thought and discussion among all collaborators. -
Book (stand-alone)Water accounting in the Awash River Basin
WaPOR water accounting reports
2020Also available in:
No results found.This report provides the water accounting study for Awash River basin in Ethiopia carried out by IHE-Delft using the Water Productivity (WaPOR) data portal of the Food and Agricultural Organization (FAO). The Awash River Basin is the most utilized river basin in Ethiopia hosting most of the industrial activities in the country, a number of small to large scale irrigation schemes and the main population centres of the country with more than 18.6 million people (2017 estimate). The basin faces high water stress during the peak of the irrigation season and frequent flooding in rainy seasons. The Water Accounting Plus (WA+) system designed by IHE Delft with its partners FAO and IWMI has been applied to gain full insights into the state of the water resources in the basin for the period 2009 to 2018. The WA+ framework is a reporting mechanism for water flows, fluxes and stocks that are summarized by means of WA+ sheets. The role of land use and land cover on producing and consuming water is described explicitly.
