Since 2021, the China Zhi Gong Party has been collaborating with east China's Anhui Province on a Yangtze River eco-environmental protection project. Faced with the complex challenge of river basin management, the party's central committee has leveraged its intellectual resources, bringing together a think tank of leading experts to launch a five-year "science and technology empowerment" initiative across the Jianghuai region, which encompasses the lower reaches of the Huaihe River and the Yangtze River. Among these experts is Zhang Wei, a member of the China Zhi Gong Party and a professor at Peking University.
Zhang Wei has led her team in monitoring biodiversity in Chaohu Lake and the main and branch tributaries of the Wanjiang River in Anhui Province through environmental DNA (eDNA) technology. This innovative approach can precisely identify minute traces of life in water and even detect invasive species that are difficult to spot with the naked eye. "We capture or collect these minute traces of environmental information and then amplify them," Zhang explained. Without the need to fish or disturb aquatic life, this technology allows scientists to assess the biodiversity of a water body simply by analyzing genetic information from water samples.
The application of eDNA technology has opened up new pathways for evaluating the effectiveness of the fishing ban on the Yangtze River and conducting biodiversity monitoring. Over the past five years, Zhang's team has worked closely with Anhui University and local environmental protection authorities to establish multiple sampling sites in Chaohu Lake and the Wanjiang River. The initiative aims to promote eDNA monitoring technology on a more comprehensive scale through targeted oversight. "We hope to set an example so that everyone can do their part to support environmental protection and monitoring in this way," Zhang said.
The significance of this announcement lies in the potential of eDNA technology to revolutionize environmental monitoring in China. By providing a non-invasive, accurate, and efficient method for assessing biodiversity, it enables researchers and authorities to track changes in aquatic ecosystems without causing harm. This is particularly crucial for the Yangtze River basin, where the fishing ban has been implemented to restore fish populations and ecological balance. eDNA monitoring can offer real-time data on the recovery of species and the presence of invasive species, informing policy adjustments and conservation efforts.
Moreover, the partnership between the China Zhi Gong Party, academic institutions like Peking University and Anhui University, and local environmental authorities demonstrates a collaborative model for science-based environmental governance. The five-year "science and technology empowerment" initiative highlights the role of intellectual resources in addressing complex environmental challenges. As Zhang's team continues to refine eDNA techniques and expand sampling sites, the technology could be adopted more widely across China, enhancing the country's capacity for ecological monitoring and protection. This approach aligns with global trends in leveraging molecular tools for conservation, positioning China as a leader in applied environmental DNA research.
