Book (stand-alone)GuidelineGuidelines for brackish water use for agricultural production in the Near East and North Africa region 2023
Also available in:
No results found.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. -
