The Yellow River, the Chinese State, and the Ecology of North China

Flowing through the North China Plain, one of China’s major agricultural regions, the Yellow River has long represented a challenge to Chinese governments to manage. Preventing floods has been an overriding concern for these states in order to maintain a semblance of ecological equilibrium on the North China Plain. This region’s environment is heavily influenced by seasonal fluctuations in precipitation, leading to a long history of famine, particularly in the late 19th and early 20th centuries when water management structures disintegrated with the deterioration of the imperial system. In the 20th century, new civil and hydraulic engineering techniques and technologies held the promise for enhanced management of the region’s waterways. After 1949, the new government of the People’s Republic used a hybrid approach consisting of the tenets of multipurpose water management combined with the tools of mass mobilization that were hallmarks of the Chinese Communist Party. The wide-ranging exploitation of surface and groundwater resources during the Maoist period left a long shadow for the post-Mao period that witnessed rapid consumption of water to fuel agricultural, industrial, and urban reforms. The challenge for the contemporary state in China is creating a system of water allocation through increased supply and demand management that can sustain the economic and social transformations of the era.

In this study, a groundwater (GW) extraction scheme was incorporated into the Community Earth System Model, version 1.2.0 (CESM1.2.0), to create a new version called CESM1.2_GW, which was used to investigate hydrologic and climatic responses to anthropogenic GW extraction on a global scale. An ensemble of 41-yr simulations with and without GW extraction (estimated based on local water supply and demand) was conducted and analyzed. The results revealed that GW extraction and water consumption caused drying in deep soil layers but wetting in upper layers, along with a rapidly declining GW table in areas with the most severe GW extraction, including the central United States, the north China plain, and northern India and Pakistan. The atmosphere also responded to GW extraction, with cooling at the 850-hPa level over northern India and Pakistan and a large area in northern China and central Russia. Increased precipitation occurred in the north China plain due to increased evapotranspiration from irrigation. Decreased precipitation occurred in northern India because the Indian monsoon and its transport of water vapor were weaker as a result of cooling induced by GW use. Additionally, the background climate change may complicate the precipitation responses to the GW use. Local terrestrial water storage was shown to be unsustainable at the current high GW extraction rate. Thus, a balance between reduced GW withdrawal and rapid economic development must be achieved in order to maintain a sustainable GW resource, especially in regions where GW is being overexploited.

Water resource carrying capacity (WRCC) is an important metric for regional sustainable development in China. It is defined as the difference between the total water supply and demand. The North China Plain (NCP) currently faces a serious water shortage if the WRCC is not managed at a sustainable level. This study focuses on applying system dynamics (SD) methodology to evaluate different water use scenarios and their associated WRCC for the NCP. System characteristics of local water resources and demand in the NCP are captured and simulated using VENSIM® software. A SD model of the WRCC is constructed which consists of five sub-systems: agricultural irrigation, population growth, urbanization level, water recycle and industrial output. The impact on the WRCC is tested through three growth scenarios: keeping the status quo, aggressive industrial growth and modest growth combined with wastewater recycle. Based on the simulation results, the WRCC that can most likely sustain economic growth without overly stressing the water supply is the one with modest growth combined with wastewater recycle.
