No.47 Report of Monitoring and Assessment of Desert Locust in Africa and Asia Issued by Aerospace Information Research Institute and CBCGDF

On August 12, 2023, No.47 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, and Sentinel series in EU, 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 dynamics of desert locust monitoring and loss assessment in Yemen, Saudi Arabia, and Indo-Pakistan border. The remote sensing monitoring results showed that, in July 2023, the desert locusts were mainly distributed in western and inland regions of Yemen, the western coastal areas and inland regions of Saudi Arabia, as well as the Indo-Pakistan border. The total damaged vegetation areas in Yemen, Saudi Arabia, and Indo-Pakistan border were 30.2, 9.4, and 12.7 thousand hectares, respectively. It is expected that in the next two months, Saudi Arabia will experience high temperatures and dry conditions that are unfavorable for the survival of desert locusts. Meanwhile, in Yemen, there will be precipitation and abundant vegetation. Therefore, the swarms within Saudi Arabia are expected to migrate southwards, flying to the western and southern coastal regions of Yemen to lay eggs and reproduce. This will result in an increase in the number of locusts within Yemen. Due to the tropical cyclones, vegetation along Indo-Pakistan will increase, providing favorable conditions for the survival of locusts, leading to an increase in the number of locusts. This period is the important growing and harvest season for crops in Yemen, as well as the important planting and growing season for crops in Saudi Arabia. It is also the main growing and harvesting season for crops in India and Pakistan. 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.

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...
