Desert Locust Monitoring in Egypt, Eritrea and Yemen in 2025/08(Spatial resolution-500m)

In August 2025, desert locusts were primarily distributed in the central Nubian Desert and the southern Toshka irrigation area of Egypt, the western lowland corridor of Eritrea, and the western Red Sea coastal provinces of Yemen, affecting 15.7, 13.9, and 17.2 thousand hectares of vegetation, respectively. Over the next two months, most parts of Egypt are expected to remain dry with little rainfall, leading to continued population decline and southward migration toward Sudan, with only scattered activity in irrigated oases. In Eritrea, localized greening in the western lowlands will support small-scale breeding and short-distance spread; occasional small numbers of adults may enter from eastern Sudan but overall density will remain low and ease by October. In Yemen, low-level activity will persist along the Red Sea coast and adjacent inland valleys, with short-range to-and-fro coastal movements; overall risk remains low. As this period coincides with the major harvest season for food crops in Egypt and Yemen, and the main growing season for food crops in Eritrea, continued monitoring is essential to prevent recurrent losses in agricultural and pastoral production.
