No.49 Report of Monitoring and Assessment of Desert Locust in Africa and Asia Issued by Aerospace Information Research Institute and CBCGDF

On October 16, 2023, No.49 Report of Monitoring and Assessment of Desert Locust in Africa and Asia was jointly released by the Team of Prof. Huang Wenjiang, Associate Prof. Dong Yingying from Aerospace Information Research Institute, Chinese Academy of Sciences (CAS) and China Biodiversity Conservation and Green Development Foundation (CBCGDF).


Integrated with multi-source Earth Observation data, e.g. meteorological data, field data,and remote sensing data (such as MODIS in the US, etc), and self-developed models and algorithms for Desert Locust monitoring and forecasting, the research team constructed the Vegetation pests and diseases monitoring and forecasting system’, which could regularly release thematical maps and reports on Desert Locust.

This report focuses on the dynamic updates of desert locust monitoring and loss assessment in Yemen and Somalia. The remote sensing monitoring results showed that, in August 2023, desert locusts were mainly distributed in southwestern Yemen, affecting vegetation areas of 32.7 thousand hectares. In September 2023, desert locusts were mainly distributed in western Red Sea coastal areas and inland regions, impacting vegetation areas of 35.9 thousand hectares; and desert locusts were also mainly distributed in northwestern Somalia, causing vegetation damage to 12.0 thousand hectares. It is expected that in the next two months, the rainfall along the Red Sea coast will be abundant, providing favorable conditions for the survival and reproduction of desert locusts. Swarms from inland Yemen will migrate towards the Red Sea coast, leading to an increase in the population of desert locusts along the Red Sea coast. Meanwhile, in northwestern Somalia, reduced rainfall is unfavorable for the survival of desert locusts. The locust swarms will migrate to the western coast of the Gulf of Aden and engage in small-scale breeding, leading to an increase in locust numbers along the Gulf of Aden coast. This period is the main harvesting season for crops in Yemen, as well as the main planting and growing seasons for crops in Somalia. It is still necessary to pay continuous attention to the dynamics of the desert locust disaster to prevent losses to agricultural and pasture production.

CBCGDF has always been contributing to this study and the series report aims to help developing countries in Asia and Africa fight invasive species and safeguard food security. The results of the report have been shared with developing countries in Southeast Asia and Africa for free, helping them improve their capability to control the impacts of desert locusts.
