“…According to the reform requirements of the central government, the agricultural water prices throughout the country will generally be adjusted to the price level of O&M costs in about 10 years, and it is also suggested that the prices in developed regions be increased to the price level of full supply costs. With the rapid development of China's economy and society, environmental pollution due to agricultural sewage is becoming more and more serious (Chen et al, 2017;Li et al, 2020;Wang et al, 2021). China's agricultural output value accounts for less than 8% of its GDP, while China's investment in environmental protection currently accounts for more than 2% of its GDP.…”

Integrated agricultural water pricing reform (IAWPR) in China: a state-of-the-art review with focus on strategic significance, policy design, reform process and case reform effect

The integrated agricultural water pricing reform (IAWPR) is by far the most systematic, complex and longest reform in the agricultural sector of China. It has lasted for decades from the stage of reform exploration to the current reform development. IAWPR can effectively address resourced price distortion and promote rational allocation of agricultural water resources. By improving China's agricultural water pricing mechanism, government agricultural subsidy mechanism, water-saving incentive mechanism, operation and management (O&M) mechanism of irrigation systems and water quota mechanism, the reform will promote water conservation in agriculture and ensure the effective operation of irrigation systems. It is a major strategic decision made by the Chinese government to address the water security challenges facing sustainable development. This paper reviews the course of the reform, introduces the policy design, key tasks and implementation of the reform, and takes Jiangsu Province as an example to demonstrate the effect of the reform, but also discusses the problems existing in the reform.

“…Rapid population growth and industrial development have created a serious pollution problem that has drastically compromised the safety of potable water sources in China. In particular, eutrophication-which results from excessive nitrogen and phosphorus in the reservoir's water source-is a significant problem [1][2][3]. Recently, eutrophication has destroyed the ecological environment and deteriorated the water quality within the water source areas, thereby threatening the health of an extremely large populace [4].…”

In recent years, freshwater resource contamination by non-point source pollution has become particularly prominent in China. To control non-point source (NPS) pollution, it is important to estimate NPS pollution exports, identify sources of pollution, and analyze the pollution characteristics. As such, in this study, we established the modified export coefficient model based on rainfall and terrain to investigate the pollution sources and characteristics of non-point source total nitrogen (TN) and total phosphorus (TP) throughout the Huangqian Reservoir watershed—which serves as an important potable water source for the main tributary of the lower Yellow River. The results showed that: (1) In 2018, the non-point source total nitrogen (TN) and total phosphorus (TP) loads in the Huangqian Reservoir basin were 707.09 t and 114.42 t, respectively. The contribution ratios to TN export were, from high to low, rural life (33.58%), farmland (32.68%), other land use types (20.08%), and livestock and poultry breeding (13.67%). The contribution ratios to TP export were, from high to low, rural life (61.19%), livestock and poultry breeding (21.65%), farmland (12.79%), and other land use types (4.38%). The non-point source pollution primarily originated from the rural life of the water source protection zone. (2) Non-point source TN and TP pollution loads and load intensities showed significantly different spatial distribution patterns throughout the water source protection area. Specifically, their load intensities and loads were the largest in the second-class protected zone, which is the key source area of non-point source pollution. (3) When considering whether to invest in agricultural land fertilizer control or rural domestic sewage, waste, and livestock manure pollution control, the latter is demonstrably more effective. Thus, in addition to putting low-grade control on agricultural fertilizer loss, to rapidly and effectively improve potable water quality, non-point source pollution should, to a larger extent, also be controlled through measures such as establishing household biogas digesters, introducing village sewage treatment plants, and improving the recovery rate of rural domestic garbage. The research results discussed herein provide a theoretical basis for formulating a reasonable and effective protection plan for the Huangqian Reservoir water source and can potentially be used to do the same for other similar freshwater resources.

“…Satola, Lukasz et al discussed the influence of a local government’s financial autonomy on governance behaviors [ 16 ], finding that local debt [ 17 ], financial input [ 18 ], and stable rural funding sources [ 19 ] are important factors for the sustainability of environmental governance behavior. In addition, rural residents’ income [ 20 ], educational level, age [ 21 ] and sex [ 15 ] have been proven to have remarkable influence on their participation in environmental governance.…”

Rural health governance is an important part of low-carbon green life, which is also related to the sustainable development and population health project in rural areas. Based on the survey data of 2343 rural residents in China, this study adopted a binary logistic regression model to explore the effects of rural residents’ social network and cognition on their participation in rural health governance. The research results show that only less than 30% of the respondents participated in rural health governance, and the proportion of rural resident participating is not high. Both their social network and cognition have a significant impact on their participation in rural health governance. Introverted communication helps strengthen the connection between rural residents, form the network and structure of rural social communication, build emotional links and common interests, and form a common cultural understanding paradigm and action framework. The extraverted communication means that rural residents gradually break away from the social network of acquaintances, which is not conducive to building a rural community. Rural residents’ understanding of behavior begins to deviate from rural culture, customs and emotional values, and the binding force of traditional culture is reduced, making it difficult to motivate them to participate in rural public life. Policy cognition can improve rural residents’ recognition of the value and significance of health governance. Responsibility awareness is the internal driving force for rural residents to participate in health governance, which can also reduce the governance cost of rural managers. Based on this, increasing rural residents’ introverted communication and cultivating their sense of responsibility are key to promoting their participation in rural health governance.
