Sustainable Utilization of Urban Water Resources—Taking River Water System as an Example

 Water resources are an important foundation for sustainable urban development. The 2023 United Nations World Water Development Report, jointly released by UNESCO and UN-Water, points out that 2 to 3 billion people in the world are suffering from water shortages. If international cooperation in this field is not strengthened, the water shortage problem will become more and more serious in the coming decades, especially in urban areas.

 


A river channel refers to the route through which river water flows, and is also a channel for water to be discharged from the land surface. Compared with the water production, water delivery process and cost of tap water, river water as a natural water source has significant advantages. It can be used in areas such as garden irrigation and road washing, effectively reducing the use of tap water, alleviating the problem of water shortage in urban areas, and reducing the cost of water delivery and production as well as energy consumption and carbon emissions in these processes. The sustainable use of river water can promote the sustainable development of cities, and at the same time, it is necessary to strengthen the supervision and governance of its use.

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...
