This paper explores whether the sponge city construction implemented in China can restore the hydrological condition of the river basins through runoff depth. The annual runoff depth was calculated based on the volume capture ratio of annual rainfall (VCRAR) and compared with undeveloped and before sponge city construction. The results conclude as follows: the current rainwater source control standard benefits the hydrology recovery in China. But the difference between before sponge city construction and undeveloped is large in 12.9% of the regions. The adjustment recommendations of the VCRAR proposed in this paper are favourable to restoring the river basin hydrology. [ABSTRACT FROM AUTHOR]

Responding to China's major environmental challenges, researchers are increasingly exploring dynamics between international non-governmental organisations, the nation-state, and local communities. Much less understood are domestic environmental non-governmental organisations (eNGOs) and their interactions with actors across scales. This paper responds by exploring domestic eNGOs and interactions with institutional actors, including international donors, and with levels of Chinese government. The practices of eNGOs in China are influenced by interactions at various scales. Rather than being directly influenced by international partners and simply constrained by state regulations, Chinese eNGOs are embedded in more complex power relations. These interrelationships are exemplified in the operations of Green Watershed, a domestic eNGO working in Yunnan Province. Green Watershed has extensive interactions with international donors and various levels of government as a result of its national campaign and long-term local projects. Relationships between eNGOs’ international donors and the Chinese government are significant in influencing eNGO practice. NGO–government relations in China are inconsistent and constantly changing owing to the diverse interests and priorities of the various levels of government. The impacts of the local practice of Chinese eNGOs are deeply informed by their relationships both at and beyond the local level. Complex interrelationships make it difficult to achieve bottom-up, participatory resource management in China. [ABSTRACT FROM PUBLISHER]

A constrained total water-use policy has been implemented to maintain sustainable water supply in some water shortage areas. Managing a constrained water-use quota (T) in water allocation is a challenging goal. This paper proposes a new framework for water allocation under total water-use constraint by utilizing the concept of the Newsboy model, commonly used in operations management and applied economics, and applying it to the Dongjiang River Basin, South China. This framework considersTas a state variable of the objective function, rather than simply dealing with it as a constraint of multi-objective analysis. Using this framework, it is revealed how different schemes ofTplay out in water allocation, and water-use warning is provided for each sector and water governor in water resources management.

The paper analyses the range of lake management organizations (LMOs) established in China and proposes management recommendations for different lake types and contexts. Based on functions, regional coverage and sectoral focus, nine LMO patterns are identified, ranging from existing agency approaches in which there is no specific lake focus or institutional responsibility to comprehensive and powerful lake basin authorities. LMO development in China faces many challenges, including a preoccupation with organizational form rather than function and objectives, duplication with existing agency functions, and insufficient lake basin management and trans-jurisdictional coordination. We therefore propose that LMOs should be tailored to specific situations and problems, drawing distinctions between plateau, urban, plain, inland and wetland lakes as well as other contexts.

For close to a decade China has been implementing ‘eco-compensation’ mechanisms to address water-related ecosystem issues. This paper examines China’s approach to eco-compensation through experience in the Lake Tai watershed. Four typologies of eco-compensation schemes are identified and analysed, primarily through a legal lens. It is concluded that while progress has been made, there is need for improved legal approaches to this complex topic. [ABSTRACT FROM AUTHOR]

Climate change, over abstraction, pollution and questionable engineering-based paradigms are contributing to a state of crisis in water governance. This paper reports on preliminary research in Lake Baiyangdian catchment, China, which has the potential to realise more systemic and adaptive forms of water governance through development and use of a method that reframes water catchment management in the form of social learning. A cross-disciplinary research group worked together with multiple-department managers and stakeholder representatives within a purposefully designed ‘learning system’ to create an insipient social learning platform. The results demonstrate the potential to reframe water catchment management in Lake Baiyangdian so as to better address the questions: who should manage the water catchment and what in the catchment should be the focus of managing?

China's rivers face major challenges arising from social and economic development, particularly associated with pollution and over-abstraction. Although these issues vary significantly across the country, China has adopted a national, unified approach to manage water resources in a river basin context. This paper assesses the legal and institutional arrangements for river basin management in terms of decentralization and centralization. It considers the appropriate roles for the different levels of government, including providing for participation and integration across these levels. It proposes strengthening institutional development and capacity building in the future. [ABSTRACT FROM AUTHOR]

China, an upstream state and a regional hegemon in the Mekong River Basin, is commonly viewed as unilaterally exploiting water resources, irrespective of downstream states (Myanmar, Thailand, Laos, Vietnam, and Cambodia). This view is derived mainly from China's unilateral exploitation of the upper watershed for hydroelectricity and navigation, raising concerns about negative socio-ecological impacts on the downstream states. However, recent empirical evidence shows that China is gradually getting involved in negotiations and processes with the downstream states, compromising with them little by little. Indications of this policy shift include: (a) its signing agreements for hydrological data exchange, (b) confidence-building with co-riparans in the Dialogue Meeting of the Mekong River Commission, and (c) multinational negotiation with co-riparians in framework of regional institutions. In light of this shift, this article argues that China is not fully enjoying its superior resources or its superior riparian position, contrary to the common view. The aim of this paper is to (1) explain and provide updated information on these negotiation mechanisms, which are attempting to resolve the upstream-downstream dispute in the Mekong River Basin, and (2) produce counterevidence against the Theory of Hegemonic Cooperation.

In 1999, the Chinese government initiated a massive conservation programme, the 'Grain-for-Green' programme, to reduce soil erosion and to improve the eco-environmental status in western China through the set-aside of sloping agricultural lands and their conversion to forest and pasture. The attitudes and perceptions of farmers towards Grain-for-Green are little known, but will eventually dictate the direction and, ultimately, the success of the project. This paper interprets surveys concerning attitudes towards environmental protection, in general, and the Grain-for-Green programme, in particular, in two small catchments in the Loess hilly area. Participatory Rural Assessment techniques are used as survey instruments mad logistic regression analysis is used to analyze farmers' attitudes towards environmental conservation and Grain-for-Green. Most respondents are positive about environmental protection and Grain-for-Green in general. However, marked differences are evident between the two small catchments: the level of farmers' environmental protection consciousness in Anjiapo catchment is higher than that in Danangou catchment. Respondents in Azajiapo catchment expressed more support for the programme than respondents in Danangou catchment. Environmental care by farmers may not be sustainable should the programme come to an end. The results provide a useful insight into the interests and concerns of farmers, which might lead to a more positive attitude in officials in the future. [ABSTRACT FROM AUTHOR]

Transjurisdictional water pollution problems are increasing in number and are becoming a significant governance problem in China. A large number of transjurisdictional water pollution disputes that have far-reaching social effects are occurring between provinces and are also frequent between municipalities, counties, towns, and villages. In this paper, several transjurisdictional water pollution cases in China, particularly in the Yellow River Basin, are discussed. The problems and causes for transjurisdictional water pollution are addressed. There are many causes for transjurisdictional water pollution problems although the key reasons are the rapid economic development, the failure of local authorities to enforce the existing laws and to implement administrative decisions, as well as inadequacies in the legal framework. Other factors include poor technology, shortage of funds, the institutional division of jurisdiction and management over water quantity and quality both administratively and legally, the lack of transparency in the decision-making process, insufficient public participation and information disclosure, poor communication, and lack of involvement of stakeholders in basin or sub-basin organizations.

The variation of hydrological processes has been extensively discussed worldwide, yet little is known about the relative impact of human activities, and the precipitation–water level relationship in urbanized, watery areas. Thus, the change in water level and the influential variables are analysed for 1960–2014 in the urbanized and watery Taihu Basin, China. The results indicate that the water level displays a significant increasing trend. Furthermore, low-oscillation and high-oscillation periods were found to have occurred in the 1960s–1970s and 2000s, respectively, by the quantile perturbation method. A strong relationship was shown between water level and precipitation in the 1960s–1980s, especially in the flood season. Since then, human activities, such as land-use change, river system degradation and hydrological structures, have played distinct roles and caused more than 82% of the annual and flood-seasonal water level variation. The results may provide a more comprehensive understanding of the hydrological processes and provide a good reference for flood control. [ABSTRACT FROM AUTHOR]

In this study, three representative concentration pathways (RCPs) and 15 general circulation models of the Coupled Model Intercomparison Project Phase 5 were used to assess the behaviour of precipitation (P) and surface air temperature (SAT) over part of the Songhua River Basin. The Water Evaluation and Planning (WEAP) model linked with SAT and P was used for monthly simulation of streamflow to assess the influence of land use/land cover and climate change on the streamflow. The results suggest that, under RCP2.6, RCP4.5 and RCP8.5, the SAT over the study area may increase in the 21st century by 1.12, 2.44 and 5.82°C, respectively. Moreover, by the middle of the 21st century, streamflow in the basin may have decreased by 19%. The decrease in streamflow may be due to changed land use conditions and water withdrawal, having critical implications for management and future planning of water resources in the basin.

Urban water governance in China has received increasing academic and policy attention owing to frequent urban water crises. Drawing on documentary analysis and field investigations, this article analyzes the administrative system and recent policy developments vis-à-vis urban water governance in China. It demonstrates the main problems of, and mechanisms for, interdepartmental and interjurisdictional coordination, and reviews new policy instruments addressing urgent urban water governance issues. The article argues that coordination mechanisms such as the river chief system are promising but their long-term effectiveness remains to be clarified, and more attention should be paid to policy enforcement and market mechanisms.

China is developing a complicated three-aspect water use control system. Spatially, the system includes river basin, province, prefecture, county, permit, and individual users; temporally, it consists of annual average and annual/seasonal frameworks; and in terms of management objectives, it combines abstraction, consumption and use. Technical consistency is required in volume, space, timing, management and reliability. Application in the Yellow River basin reveals consistency problems in targets, indicators, timings and control periods. We suggest improving the system by addressing temporal and spatial inconsistencies, reforming management systems and procedures, strengthening research, and developing a water accounting system.

This article examines the recent changes in China's Mekong River policy and investigates the contributing factors. In the past few years, China has shifted from an upstream sovereignty stance to launch a multilateral transboundary water diplomacy initiative in the Mekong River basin through the Lancang-Mekong Cooperation Mechanism. We conclude that China's adoption of water diplomacy in the Mekong River is partially attributable to international activism by the Yunnan provincial government and its associated actors.

Rapid urbanization in China has severely disturbed the underlying surface and river systems. The stream structure parameters of Suzhou City were analysed to study the evolution and spatial differentiation of a water system undergoing urbanization. The influencing pattern of different urbanization processes on river system structure and hydrological processes was detected by statistical methods and simulation analysis. The results show that urban sprawl is influenced by both the natural environment and the social economy. At different stages of urbanization, the spatial urban expansion and the natural river characteristics influence the evolution of the river network: during rapid urbanization, the decline in surface water ratio and river density is more intense. The decrease of surface water ratio and river density in rapidly urbanized areas was greatest, followed by that in area urbanized in the 1980s, with few changes in the old town. Under high urbanization, river system indicators tend to stabilize. The rivers' hydrological features were affected by urbanization, with water yield in the study area increasing from 0.81 to 0.95 m3/m2 (1991–2015). The same rainfall intensity results in higher flood levels and greater risk of flooding under rapid urbanization. [ABSTRACT FROM AUTHOR]

With the rapid economic development and urbanization in Taihu Basin (eastern China), the river system has decayed and the connectivity of rivers and lakes has weakened, resulting in frequent floods. The impact of changes in river system structure on hydrological processes in the plain river network area was analysed against a background of urbanization. An indicator system was built to describe the quantitative, morphological and spatial structure of the river system. Analysis of the change in annual average and extreme water levels revealed the influencing mechanism of the changes in river system structure on the hydrological processes. The results indicate a decreasing tendency in the density of the river system in the study area, with a reduction in water surface ratio by about 20% in the past 50 years. Since the 1960s, the maximum and annual average water levels have increased. The degree of change in the mean monthly, annual lowest and annual highest water levels was great, with that in the non-flood season being higher than in the flood season. The decrease in the number of rivers directly reduced the storage and adjustable capacity of the basin. [ABSTRACT FROM AUTHOR]

Failure to curb water pollution in China brings to the fore the issue of environmental values and attitudes among Chinese farmers. Applying the New Ecological Paradigm Scale this study finds that the pro-environmental value ofNew Ecological Paradigm (NEP) Worldviewhas a stronger standing among the studied Chinese farmers than theDominant Social Paradigm (DSP) Worldview.

Drawing on empirical evidence from a case study conducted in the upper Mekong catchment, this article assesses the performance of the Erhai Lake Basin Management Commission, an organization mandated to control pollution and integrate the diverse interests of those individuals and communities living and working near Erhai Lake. Clear local rules, strong enforcement, practical protocols, clear responsibilities and extensive mobilization have been crucial to the success of this small river basin organization. However, the insufficient involvement of numerous important stakeholders in decision-making processes has decreased the commission’s capacity to address water issues. [ABSTRACT FROM AUTHOR]

Most of China’s surface waters are undergoing anthropogenic eutrophication, mainly due to leaching of phosphorus (P) from both sewage and agriculture. This is causing quality deterioration in their scarce water resources. The problem has been acknowledged by Chinese authorities and actions sought implemented, though expected ameliorations are on hold. This interdisciplinary study focuses on actions taken by farmers adjacent to Yuqiao reservoir; the raw water source for five million people in Tianjin City. As is often the case, these farmers apply excessive amounts of fertilisers. The leaching of P is aggravated by poor P sorption capacity of the soils and a practically impermeable clay layer below a shallow ploughing layer. During heavy rainfalls the soils become saturated, causing P to be flushed out through shallow-water flow paths. A low content of organic matter in the soils makes things worse. This study documents how farmers are taking action to improve crop yield, the environment, and health issues. Farmers taking more action than others consider themselves as having good farming competence, they are usually local members of the Chinese Communist Party (CPC), and have a relatively low family income. The study concludes with suggested policy measures. The main recommendation is to collect household sewage and most of their manure and use it as feedstock for large-scale biogas reactors, combined with returning the residual organic matter to the soil. Cooperating with well-respected farmers and drawing on local CPC members’ willingness to take action may facilitate a successful implementation of the above measures. [ABSTRACT FROM PUBLISHER]

The Sichuan Basin Region is important composition part of the upper reaches of the Yangtze River. Eco-environment change in this region exerts important effect to the middle and lower reaches of the Yangtze River. The forest cover had hugely been reduced from the 1950s to the mid-1970s, and it has obviously been increased since the end of the 1970s, because that the reforestation project has been implemented. The water source conservation capacity in the studied watersheds has been getting better through study and analysis of the methods for assessment of the forest hydrologic effect. It is found that the method of index of the water source conservation capacity can be used to assessment of the forest water source conservation in the big scale watershed in the studied region. In addition, the retention water capacity of the different vegetation vertical zones in the typical mountain in the north-western Sichuan Basin was studied, its result provides the base for protection and building of the forest ecosystem in the mountain area in the studied region.
