Temperate grain legumes, including faba bean, field pea, chickpea, lentil, and grass pea, are important food and forage crops in the cereal-based cropping system in the Nile Valley and Red Sea region countries. Despite their importance, local production remains insufficient, and the countries are forced to import to narrow the demand gaps. Emerging diseases, such as faba bean gall disease and several viruses (Chickpea chlorotic dwarf virus, Chickpea chlorotic stunt virus, Faba bean necrotic yellows virus, and Pea seed-borne mosaic virus), are on the rise due to climate variability, changes in farming systems such as monocropping, reduced crop rotations, limited knowledge about the pathogens, and absence of varieties with good levels of resistance. This review synthesizes research achievements in the region and identifies focus areas, primarily resistance breeding, characterization of pathogen populations, developing efficient screening techniques, investigations of mixed virus infections, advancement of pathogen diagnostic techniques, and developing agroecologically based disease management strategies to reduce economic impacts of new and re-emerging diseases. Moreover, research collaboration and information exchange among countries in the region are essential to mitigate the growing threat of emerging legume diseases.
