Studie der Umweltschutzorganisation The Nature Conservancy, 18.4.2016 (engl. Originalfassung)
China is experiencing the full force of these water security challenges. At least one-third of China's lakes and rivers are too polluted for human use, and 73 percent of the watersheds that supply water to fast-growing cities face medium to high pollution levels. Given the rise of cities and the scale of the water quality challenge, we must work together to build a sustainable water future for China.
For the past several years, The Nature Conservancy has been studying the state of water around the world. This year, we decided to dive deeper into China given the country's challenges and importance to the global economy, environment and human development. In our latest report, the China Urban Water Blueprint, we analyzed the state of the 135 surface water sources tapped by China's 30 largest and fastest growing cities, and we found opportunity.
Roughly half of China's water pollution comes from land use and degradation, especially fertilizers, pesticides, and livestock waste carried into lakes, rivers, wetlands, aquifers and coastal waters. By restoring forests, improving agricultural practices and implementing other conservation solutions alongside traditional water infrastructure, China can improve water quality for more than 150 million people and reduce pollution that impacts nature. Additionally, savings in water treatment could offset a significant portion of the catchment conservation costs.
