Southern Africa locust outbreak, September 2020


Key messages

× At least four Southern African countries (Botswana, Namibia, Zambia and Zimbabwe) are facing serious outbreaks of African Migratory Locust (AML), threatening the winter crops and the main planting season due to start in October.

× Seven million people who are still recovering from the impact of the 2019 drought, may experience further food insecurity and following crop damage from the AML (Note: this is separate to the Desert Locust emergency in Eastern Africa).

× The Food and Agriculture Organization of the United Nations (FAO) is working closely with the Southern African Development Community (SADC) and the International Red Locust Control Organization for Central and Southern Africa (IRLCO-CSA) to support the affected countries to respond to the locust outbreaks. It should be noted though, that IRLCO-CSA primarily focuses on the control of a different locust pest: the Red Locust.

× Awareness of the situation is low due to the absence of dedicated national locust units and, consequently, a lack of regular monitoring and reporting.

× FAO promotes preventive strategies for locust management, which rely on early warning and early reactions. Delaying the response would prove more costly financially, environmentally, socially and economically.

× The build-up and spread of the pest could exacerbate the impacts of COVID-19 and threaten the next planting season.

× Urgent actions are needed to identify locust hotspots and ensure the pest is controlled in them.

× The capacity of countries to monitor the spread of the pest through regular surveillance and mapping should be enhanced in order to increase their ability to take timely and anticipatory action to prevent the pest from causing serious damage to crops and pastures.

× The impacts of COVID-19 and restrictions on movement are hampering effective monitoring of the evolution of the pest populations.

× The 2020/21 la Niña event could accelerate the multiplication of the AML in the affected areas and increase the threat it poses to crops, grazing and livelihoods.
