Synopsis (short abstract) Water scarcity is one of the major challenges in the 19 countries of the Near East and North Africa (NENA) region. The lack of water is affecting important irrigated areas, limiting the increase of food production needed to address the growing demand due to population growth. In most countries of the NENA region, the need to use non-conventional water resources, including brackish water, is well recognized. Brackish water is loosely defined as water that is more saline than freshwater, but less saline than seawater. It covers a large range of salinity levels, from 500 to 30 000 mg/l of total dissolved solids (TDS). Despite the presence of large amounts of brackish water and its potential for use in growing a number of crops, it is only used in limited amounts for irrigation. The successful use of brackish water for irrigation requires a basic understanding of scientific principles affecting the interactions among the climate, the applied water, the soil, the crop, and the environment. Equally important is the application of suitable technology and management practices that will facilitate the optional use of this poor-quality water. The successful use of brackish water requires a higher level of management and likely the adoption of new irrigation management practices. Because climate, water quality, soil type, and crop tolerance to salinity vary from location to location, guidelines, with some degree of site-specific flexibility, must be developed.

    The State of Land and Water Resources for Food and Agriculture in the Near East and North Africa region
    Summary Report
    2022
    Also available in:
    The State of Land and Water Resources (SOLAW) in the Near East and North Africa (NENA) region is part of a FAO flagship series launched in 2011. Being one of the most land and water scarce region in the world, the preservation of land and water resources is of critical importance to ensure food security and address the increased food demand. The publication aims at providing policy makers, institutions and other stakeholders a comprehensive overview of the current situation for land and water and the effect of climate change and urbanization on food production facilitating informed decision-making. The report provides the latest land and water resource statistics for the region and outlines important challenges that NENA is facing in the lead up to 2030 and beyond. It also presents positive initiatives from the region and a range of options available to help authorities respond to the issues of land and water resources.

    The solution to water scarcity in the Near East and North Africa (NENA) region has been illuminated through the "2030 Agenda for Water Efficiency/Productivity & Water Sustainability (WEPS)" project. This initiative has brought significant breakthroughs in eight target countries, namely Algeria, Egypt, the Islamic Republic of Iran, Jordan, Lebanon, Morocco, Tunisia, and Palestine. The accomplishments include the adaptation of water accounting standards in line with global and scientific criteria, the endorsement of the water–energy–food nexus approach, and the development of top-tier knowledge products that have fostered knowledge sharing across these nations. However, challenges like the pandemic aftermath, initial implementation hiccups, and gender inclusion hurdles have arisen. Moving forward, the emphasis is on continued advocacy and collaboration, bolstered commitment to the water–energy–food nexus, expansive knowledge outreach, and enhanced regional partnerships, with an aim to integrate the insights gained into future regional plans.
