    This is the fundamental scope of the Irrigation Benchmark Project, where the emphasis was placed on introducing and implementing new water saving technologies. Additionally, emphasis was laid on the participation and involvement of farmers in water users’ associations (WUA) and other community organizations, as well as with government organizations – particularly, those concerned in the Extension Service of the Ministry of Agriculture.

    The objective of any national water policy is, normally, to ‘Generate the maximum possible economic value for the nation’. Under water scarcity situations, water should be allocated so that users who generate a higher income per unit volume of water are given priority over those who generate less income. This applies not only to water quantity, but also to water quality. The above statements are valid when water is considered as an economic commodity.

    Almakatei village, located on Alatf canal, was selected purposely to represent the community. Its agricultural land is located across three main districts in Menoufia Governorate – Al Bagour, Shebin Al Koum and Quesna. This was considered as one of the main advantages of selecting this site. El-Menira tertiary on Alatf canal was selected as the site for the study of the pipeline group. It is about 870 m long and it serves an area of about 40 ha. El-Hamra tertiary was selected for the study of the open canal group and serves an area of 30 ha.

    This will ensure more sustainable ecosystems and improved rural livelihoods. Emphasis is given to building on local knowledge by using existing data, social capital, research linkages, partnerships and proven methodologies and technologies in the region thereby ensuring the sustainability of the impacts achieved. The Initiative also draws from a wide pool of multi-disciplinary expertise from within and outside the region and targets the three major agro-ecosystems in the region – rainfed, irrigated and rangeland.

    Irrigation management of crops in Egypt is characterized by the application of more water than the crops require. In fact, large amounts of water are supplied without any estimates of the soil water content at the root zone. The rationale for doing so is the assumption that more irrigation water means a greater yield. So, eliminating the use of this unnecessary irrigation water could help save the resource, provided that this can be done with low yield losses.

    In this study, an economic evaluation of water-use efficiency technologies proposed and tested by the agronomic team in the Tadla Irrigated Perimeter was carried out. To capture climatic variability, the analysis was conducted during two contrasting years (dry and wet). Total annual rainfall was 357 mm in 2005/06 (wet year) and 296 mm in 2006/07 (dry year). During the first year, precipitation was well distributed throughout the season. However, the second year was wet at the beginning, dry in the middle and very wet at the end of the season.

    • Drainage system problems;
    • High water table;
    • Increased soil salinity;
    • Seawater intrusion;
    • Pollution due to extensive use of chemicals; low water quality;
    • Available water increases relatively in winter;
