China: Improving Water Resource Management & Pollution Control in the Hai Basin
September 3, 2012
The Hai Basin Integrated Water and Environment Management Project (September 2004 - June 2011) has effectively promoted an integrated approach to water resource management and pollution control in the Hai Basin in northern China and contributed to the restoration and protection of marine environment, ecosystem and biodiversity in the Bohai Sea.
The project was implemented in 16 counties in northern China. Over 20 million people benefited from it.
The Hai Basin spreads over six provinces and the municipalities of Beijing and Tianjin, which account for 15 percent of China’s GDP. It suffered from serious water-related problems, including water pollution, water scarcity, diminishing water supplies and flooding. Water availability per capita in the Hai Basin was only 14 percent of the national average and about four percent of the global average.
Over-exploitation of groundwater, overuse of surface water resulting in inadequate environmental flows, along with groundwater and surface water pollution, led to the decline and deterioration of water resources and damaged the freshwater and coastal environments of the Hai Basin.
The Basin discharges into the Bohai Sea, which is an important ecosystem and fishery resource. However, heavy land-based pollution from urban, industrial, agricultural, and other sources in the Hai Basin, combined with overfishing, reduction of freshwater inflows, and habitat loss, threatened the fishery and steadily diminished many of the Bohai Sea’s ecological functions.
To address these problems in the Hai Basin and the connected Bohai Sea ecosystem, the World Bank helped the Chinese Government develop and implement an integrated approach to water and environmental management. The project was designed to play an important role in these efforts.
Integrated water and environment management (IWEM) planning is a key management measure promoted by the project. It provides the context (within law, policy, institutional arrangements, and operational practices) for the development of practical approaches to carry out top-down, bottom-up, vertical and horizontal cooperation at the basin, sub-basin and county level that redress land-based activities that degrade marine waters.
Another innovative approach introduced by the project is evapotranspiration (ET) management, with the aim of achieving real water savings to eliminate groundwater overdraft and provide more surface water for ecological purposes and as outflow to the Bohai Sea. Remote sensing and geographic information system (GIS) techniques were used to develop Basin-level ET reduction plans.
Furthermore, the project promoted improved coordination at all levels to overcome the institutional barriers to IWEM.
- Integrated and coordinated management of water resources and environment The project established a mechanism for cooperation between water and environment departments at the central, provincial, and local levels.
- Reduced discharge of wastewater and key pollutants Annual wastewater discharge inthe 16 project counties in 2010 was 129.34 million tons less than that of 2004; COD and NH3-N discharge was 69,758 tons and 7,488 tons less.
- Controlled groundwater over-exploitation Total amount of over-exploited shallow groundwater for agricultural irrigation in the 16 project counties in 2010 was 63.2 percent less than that of 2004; deep groundwater exploitation was down by 46 percent.
- Reduced ET Value In 2010 the 16 project counties had an average ET of 549.6 mm, down by 54 mm from the 2004 level.
- Yingcheng Wastewater Treatment Plant in Hangu District, Tianjin, was built, and financial incentives for wastewater treatment were put in place in the small towns of Tianjin.
- Clearing of key pollutants in the Dagu Canal in the Hai Basin The project cleaned a total of 6.26 million m3 of pollutant sediment in the Dagu Canal. It also cleared 28,670 tons of oil, 1,820 tons of zinc, and 13,378 tons of total nitrogen from the Canal.
- Public participation Over 400 water users associations were established so that the communities decided themselves on how they manage water resources, particularly on water savings and operation and maintenance of the on-farm water systems.
- Practical approaches to improving water and environment management were developed, which can be replicated throughout the Hai Basin and in other Chinese basins.
It used to take us 20-30 days to irrigate the farmland I work on. Now 7 days is enough
Bank Contribution and Partners
The Global Environment Facility (GEF) provided a grant of US$16.96 million. The project was jointly implemented by China’s Ministry of Water Resources and the Ministry of Environmental Protection, as well as the municipalities of Beijing and Tianjin and four provinces. The central and local governments provided US$17.56 million in counterpart funding.
The project provided innovative ideas, approaches and successful experience for China to build a “resource-saving” and "environment-friendly” society, including practical collaboration between multiple departments, improving water-related regulatory systems and institutions, strengthening knowledge-based management of river basin water and environment, establishing grassroots water management and service systems, and raising public awareness and participation.
Better water use and pollution control in the Basin has improved residents’ health and living standards, eliminated odors and ameliorated aesthetic and recreational conditions.
Farmers also benefited from more efficient consumption-based irrigation management, which increased water productivity, crop yields and household incomes. In the longer term, benefits will also accrue to fishers and people fringing the Bohai Sea through improved water quality, fishery stocks and biodiversity.
"It used to take us 20-30 days to irrigate the farmland I work on. Now 7 days is enough,” said a farmer at the project management office’s meeting with villagers in Beidonggu Village of Guantao County, Hebei Province.
"In my village, before on average, one household needs three people for farm work. Now most households need only one member in the fields. And it no longer requires male labor. So men can seek for more remunerative, off-farm work and contribute to household incomes more,” said a farmer at the project management office’s meeting with villagers of Wuji Village of Cheng’an County, Hebei Province.
