A low-cost integrated desalination and irrigation technique tested on dual-purpose sorghum in Turkana County, Kenya

In arid and semi-arid lands, water salinity often restricts plant growth, degrades soils, and even causes irrigation systems to fail, especially in hot climates. Worldwide, it is a “major cause” of the irrigation-induced salinization that had already affected 76 million ha of soil in 1991. Our novel and inexpensive irrigation technique addresses these issues, thus potentially improving the food security of...
