Quartz published on 4 November 2022 an article titled "To Save Water, Egypt Should Farm Fish Instead of Crops" by Tim McDonnell.
Egypt is the top producer of farmed fish in Africa. Fish farming produces more protein and revenue per acre than crop farming, and with a lower water and carbon emissions footprint per kilo of product. While water is used only once in agriculture, fish farmers are able to use it several times. Although there are challenges, the author urges that Egyptian farmers move increasingly from crops to fish to conserve water and increase protein production.
