China's Water Pollution: Strategies And Solutions

China has implemented various measures to reduce water pollution, which has become a pressing issue due to the country's rapid industrialization, urbanization, and economic growth. In recent years, the Chinese government has introduced over 130 policies to address water pollution and aquatic environment degradation, including the State Council's Action Plan for Prevention and Control of Water Pollution. To improve water quality, China has also adopted the River (Lake) Chief System, appointing top officials as lake or river chiefs to oversee specific jurisdictions. Additionally, China has invested in technical improvements, such as automated water monitoring systems and water quality applications. However, challenges remain, including financing problems and compliance failures at the local level. China's water pollution issues are further compounded by climate change, with extreme weather events and rising temperatures impacting water resources.

The Chinese government has implemented over 130 policies to address water pollution

Water pollution in China has been a major concern for decades, with the country's rapid industrialization, urbanization, and economic growth contributing to the issue. The Chinese government has acknowledged the severity of the problem and implemented numerous policies to address water pollution and improve water quality. Indeed, the government has introduced over 130 policies aimed at reducing surface water quality degradation and protecting the aquatic environment. These policies have been implemented as part of comprehensive plans, such as the 12th Five-Year Plan (2010-2015) and the State Council's Action Plan for the Prevention and Control of Water Pollution (Water Ten Plan).

One of the key approaches China has adopted is the River (Lake) Chief System (RCS). Under this system, top officials at various levels of government are appointed as lake or river chiefs, with their jurisdictions. The RCS aims to improve water quality and address the issue of divided responsibilities among government agencies, which has been a challenge in the past. As a result of the RCS, the number of water bodies with improved water quality has increased.

In addition to the RCS, China has also invested in "green" solutions through the sponge city initiative. This initiative aims to create eco-cities that support the local urban water cycle, reduce flooding, and strengthen resilience against climate change-induced extreme weather events. The sponge city concept has already been implemented in major cities such as Shanghai and Beijing, with the goal of having 80% of urban areas absorb and reuse water by 2030.

Furthermore, China has also introduced laws to protect its rivers. One notable example is the Yangtze River Protection Law (YRPL), enacted in March 2021, which aims to safeguard the country's longest river through ecological protection and restoration. This law is a significant milestone in China's legislation on ecological protection and is expected to lead to similar protection laws for other rivers in the country.

While China has made significant efforts to address water pollution, challenges remain. Climate change-induced extreme weather events, such as droughts and floods, continue to impact the country's water resources and quality. Additionally, there is a need to balance economic development with environmental protection, especially in regions with insufficient water resources. Nevertheless, the Chinese government's commitment to implementing various policies and initiatives demonstrates its recognition of the urgency to tackle water pollution and improve the country's water security.

China is building a massive network of wastewater pipelines

China is in the process of constructing a massive network of wastewater pipelines to combat severe river pollution. This initiative is part of the country's high-profile anti-pollution drive, which aims to reverse the damage caused by decades of breakneck economic growth, industrialization, and urbanization.

The Scale of the Problem

China's rapid economic development, industrialization, and urbanization have resulted in widespread water pollution, with approximately 700 million people consuming contaminated drinking water. The volume of wastewater produced is projected to double from 1990 levels to almost 78 billion tons by the year 2000. This has led to alarming trends with potentially serious consequences for human health and the environment.

The National Water Pollution Action Plan

Under the 2015 National Water Pollution Action Plan, Chinese cities are under pressure to reduce "black and stinky water" in urban rivers. To achieve this, the country needs to invest over 1 trillion yuan ($148 billion) in building an additional 400,000 kilometers of wastewater pipelines. Each kilometer is estimated to cost 3 million yuan, posing a significant financial challenge to local authorities.

Progress and Challenges

While the central government has demonstrated its commitment to tackling water pollution, the clean-up program has faced obstacles due to financing problems and compliance failures at the local level. Some local governments believe that improving the environmental situation will harm economic growth and often complain about a lack of funds to address pollution. However, experts argue that improving the environment can attract more property and other investments.

The Impact of Climate Change

In addition to industrial and agricultural pollution, China is also grappling with the impacts of climate change, including more frequent and intense extreme weather events such as droughts and floods. These events further strain water resources and highlight the urgency of addressing water pollution and improving water management.

The Way Forward

China has implemented various policies and initiatives to reduce water pollution, including the River (Lake) Chief System, which aims to improve water quality and streamline governance by appointing top officials as lake or river chiefs. The country has also shown interest in green solutions through the sponge city initiative, which integrates natural and grey infrastructure to enhance urban water cycle management.

International Cooperation

China has also actively participated in global efforts to combat climate change and environmental degradation, signing the Paris Agreement and pledging to be carbon neutral by 2060. However, experts argue that more ambitious goals and effective implementation are needed to align with the Paris Agreement and address the interconnected challenges of economic growth, environmental protection, and public health.

Citizen science is being used to address water challenges

China's rapid economic growth, industrialization, and urbanization, coupled with inadequate investment in basic water supply and treatment infrastructure, have resulted in widespread water pollution. Over half of China's population consumes contaminated drinking water, with levels of animal and human excreta exceeding maximum permissible levels.

China has been working to address this issue through various measures, including the implementation of a national water pollution action plan in 2015, which aims to reduce "black and stinky water" in urban rivers. This term refers to heavily polluted and malodorous urban water. To achieve this goal, China plans to build a massive network of wastewater pipelines, requiring over 1 trillion yuan in investment.

Citizen science has played a crucial role in addressing water challenges in China. A government-backed citizen science app, the "Black and Smelly Waters App," launched in 2016, enables citizens to report polluted bodies of water, complete with photographs, descriptions, and rankings based on their level of pollution. This app helps identify overlooked sites of urban water pollution and strengthens accountability for cleanup efforts. While challenges remain, the app has led to significant improvements in water quality in targeted areas.

The success of citizen science in China is further supported by a study examining the impact of citizen monitoring of waterways. The study found that disseminating monitoring results to local and provincial governments improved water quality. This is particularly effective when information makes local resource managers accountable to higher authorities.

Overall, citizen science initiatives in China are making a significant contribution to addressing water pollution challenges by empowering citizens to take an active role in identifying and addressing polluted sites, and by supporting government efforts to improve water quality. These initiatives hold promise for the future of China's environmental management and the health of its citizens.

The River (Lake) Chief System has been established to improve water quality

The River (Lake) Chief System has four main levels: provincial, municipal, county, and township. River chiefs are responsible for safeguarding water resources, managing river and lake waters and shorelines, preventing and controlling water pollution, managing the water environment, bolstering water ecological restoration, and supervising rivers and lakes.

The system has been implemented in 31 provinces, with over 300,000 river and lake chiefs appointed at the provincial, municipal, county, and township levels. Additionally, 900,000 river and lake chiefs have been designated at the village level.

The River (Lake) Chief System has been credited with improving water quality in China. For example, in Beijing, the system has contributed to the ecological management of rivers and lakes, with a marked decline in ecological issues from 2019 to 2021. However, there are also regional disparities and urban-rural divergences in the effectiveness of the system.

Some weaknesses and challenges of the River (Lake) Chief System include unclear responsibilities of river chiefs, overreliance on administrative power, trans-provincial management complexities, and a lack of public participation and social supervision. To address these issues, the Chinese government has been working on strengthening the legal framework, improving the management system, and promoting public participation.

Overall, the River (Lake) Chief System has been established as a comprehensive approach to improve water quality in China, with a focus on collaboration, accountability, and differentiation.
