“…As the capital of China and a flourishing international mega-city, Beijing is facing an unparalleled challenge in water resources [38][39][40]. The Miyun Reservoir, Beijing's only surface water source for domestic water supply, is playing an increasingly crucial role for the urban water supply [41,42].…”

Abstract:As the only surface water source for Beijing, the Miyun Reservoir and its catchment (MRC) are a focus for concern about the degradation of ecosystem services (ES) unless appropriate payments for ecosystem services (PES) are in place. This study used the contingent valuation method (CVM) to estimate the costs of two new PES programs, for agriculture and forestry, and to further calculate the economic value of ES in the MRC from the perspective of local rural households' willingness to accept (WTA). The results of Logit model including WTA and the variables of household and village indicate that the local socio-economic context has complex effects on the WTA of rural households. In particular, the bid amount, location and proportion of off-farm employment would have significant positive effects on the local WTA. In contrast, the insignificance of the PES participation variable suggests that previous PES program experiences may negatively impact subsequent program participation. The mean WTA payments for agriculture and forestry PES programs were estimated as 8531 and 8187 yuan/ha/year, respectively. These results consistently explain the differentiated opportunity costs on both farmland and forestry land. Meanwhile, the differentiated WTA values in Beijing vs. the surrounding Hebei Province follow the interest differences and development gaps between jurisdictions. Finally, the total economic value of ES in the MRC area was estimated at 11.1 billion yuan/year). The rational economic value of ES for the restoration priority areas reaches 515.2 million yuan/year. For the existing budget gap (299 million yuan/year), the study proposed that decision makers increase the water tariff by 0.08 yuan to raise the funds needed. The study also concluded that these results are not only financially and politically feasible but also cost-effective. This study has policy implications for improving the implementation efficiency and providing quantified supports for PES programs in megacity source water area.

“…But these theories were mainly concentrated on the carrying capacities of natural resources (Di et al 2007), among which, the carrying capacities of land and water resources have been studied for a long time and some fruitful research results have been achieved. And some others, such as human carrying capacity (Graymore et al 2010;Yue et al 2008;Zhang et al 2010), environment carrying capacity (Arrow et al 1995), aquaculture carrying capacity (Duarte et al 2003), etc., were also used to assess the regional sustainability. The concept of WRCC was first suggested by the China Xinjiang Water Resource Soft-Science Research Panel in 1989.…”

Regional sustainable development is an important focus on natural resources management, and also is a critical requirement for socio-economic system's sustainability. Water resource is one of the most important supports for the sustainable development of society and economy. The study proposed the concept of water resources carrying capacity (WRCC) to assess the scale of economy and population that the local water resources can support. And the study took Tianjin city of China for an example, and its population size and economic scale were chosen as two main indices. Based on the historical statistical datum, the carrying index (CI) and index of water supply-demand balance (IWSD) were evaluated, and then the current WRCC in Tianjin city and its dynamic tendency were evaluated by means of the method of carrying capacity of relative resources (CCRR). The results showed that the utilization of water resources in Tianjin is inefficient for now, the dynamic trend would be partly rational after the protection policy of water resource was put into practice in 2010 and 2020, and the WRCC of Tianjin city went beyond the average WRCC of China and was roughly equal to that of Beijing city. This paper showed that the rational policies and measures should be established and implemented to make sure utilize water resources efficiently in Tianjin city.Keywords Water resources carrying capacity · Carrying capacity of relative water resources · Carrying index · Index of water supply-demand balance · Tianjin City of China

“…The indices within the system should also be computable and comparable [29] . Based on this principle, the actual situation in Heilongjiang Province and relevant results obtained by other researchers [30,31] , the 15 assessment indices that have the most significant impact on the exchange of matter and energy through the periphery of the water and land resource system were selected as order parameters to establish a risk assessment index system for the coordination and order of water and land resources in Heilongjiang Province (Table 1). Notes: "+" signifies that the greater the index is, the greater the degree of coordinated order in the system is and the lower the risk in the system; "-" signifies that the smaller the value of the index is, the greater the degree of coordinated order in the system is and the lower the risk in the system.…”

Coordinated and orderly water and land resource system is vital to ensure the economic and social development of a region. Grain production in Heilongjiang Province has increased consecutively every year since 2003, and numerous water and land resource-related problems have become increasingly prominent and have had significant adverse effects on social and economic development and stability in the region. In this study, Heilongjiang Province and its 13 prefecture-level cities were selected as the study area, and the degrees of coordination of the social, economic and ecological subsystems were evaluated using periphery theory and the theory of synergetics. To ensure that the assessment was objective and accurate, weights were calculated using the projection pursuit technique, and similarity degrees were calculated using a modified (by introducing the chi-square distance) order of preference by similarity to ideal solution (TOPSIS) technique. Moreover, to reflect the variations in the overall degree of coordination in Heilongjiang Province, the risk level of the coordination of the water and land resource system was predicted through the year 2020 using a dynamic neural network. This study provides a reference for establishing effective and balanced coordination between society and water and land resources.
