Desert Locusts Increasing along the Red Sea Coast in the Next Two Months | No.50 Report of Monitoring and Assessment of Desert Locust in Africa and Asia Issued by AIRI-CAS and CBCGDF

On November 17, 2023, No.50 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 Saudi Arabia. The remote sensing monitoring results showed that, from August to October 2023, the desert locusts in Saudi Arabia mainly migrated from the inland areas towards the southwest along Red Sea coast. The damaged vegetation areas were 9 thousand hectares, 10.1 thousand hectares, and 11.5 thousand hectares, respectively. It is predicted that in the next two months, abundant rainfall along the Red Sea coast of Saudi Arabia will create favorable conditions for the survival and reproduction of desert locusts. Swarms of locusts from the inland areas of Saudi Arabia are anticipated to continue migrating towards the Red Sea coast, engaging in small-scale breeding. As a result, the insect population along the Red Sea coast is expected to increase. This period is the main planting and growing seasons for crops in Saudi Arabia. It is still necessary to pay continuous attention to the dynamics of the desert locust disaster to prevent losses to agricultural and pasture production. The specific research results are as follows. 

In August 2023, desert locusts within Saudi Arabia were primarily concentrated in the southwestern inland areas. In September 2023, the Red Sea coastal areas in the southwestern part of Saudi Arabia experienced abundant rainfall, resulting in thriving vegetation and providing favorable conditions for the oviposition and reproduction of locusts. 



In October 2023, the Red Sea coastal areas in the southwestern part of Saudi Arabia experienced abundant rainfall, resulting in thriving vegetation and providing favorable conditions for the oviposition and reproduction of locusts. 


The comprehensive analysis shows that, in the next two months, it is expected that there will be abundant rainfall along the Red Sea coast of Saudi Arabia, creating favorable conditions for the survival and reproduction of desert locusts.

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.

Unveiling the Mysteries of Cetaceans in the South China Sea: Chinese Scientists Describe Important Marine Mammal Areas (IMMAs)

Image
The world’s ocean ecosystems are facing mounting threats—climate change, marine pollution, overfishing, and habitat destruction due to human activities, to name a few. These pressures are particularly dangerous for marine mammals like cetaceans, whose survival hinges on healthy habitats and stable populations. Yet, in regions like the South China Sea, where biodiversity is exceptionally high, little research has been done to understand the needs and habitats of cetaceans. This lack of data has left a gap in our knowledge and made it challenging to establish targeted conservation strategies. Recognizing this, Chinese scientists have now set out to fill these gaps and contribute essential data to inform future policy and management, aiming to protect these vulnerable species and support the objectives of the Kunming-Montreal Global Biodiversity Framework (GBF). In a landmark study published on October 8, 2024, in Biological Conservation, Dr. Li Songhai and his team from the Institute of
