“…Land subsidence triggers direct economic loss and external cost incurred in the effort to rehabilitate damaged construction, infrastructure and farmland [36] [37]. Hu et al [38] revealed that land subsidence in coastal areas caused a huge economic loss. In the peat land, we found that land subsidence at a traditional canal system destroyed cultivated areas.…”

Land subsidence can have a considerable impact on the socio-economic viability of areas. In urban areas, land subsidence tends to damage buildings and infrastructures gradually, while in rural peat land it slowly destroys vegetation. The damages will worsen since climate change has further implications for the areas affected by land subsidence. In Indonesia, the response to land subsidence varies in different areas in terms of awareness, urgency and action on the part of both public authorities and land users. This paper systematically investigates these varied responses in urban and rural peat land areas. Interviews with experts and surveys of 330 land users in selected sub-districts were conducted and further supplemented by focus group discussions. We found that both the public authorities as well as the land users' responses were considered as of limited value to contest land subsidence. We suggest that the endorsement of land users' response into governmental policies would make a significant difference in improving land subsidence management.

“…Although it has decreased by 13.09 m from historical levels owing to the overexploitation of groundwater and still requires recovery. The recovery of the groundwater levels help minimize geological damage and economic loss caused by land subsidence associated with extensive groundwater production (Hu et al ; Yang ). In addition, the transfer water from the MR‐SNWDP has not only ensured the domestic water supply and restored the groundwater level but also provided more water for additional industrial development that could further support economic growth in the water receiving areas (Yang, Yin, et al ).…”

Research Impact Statement: Importance of the MR-SNWDP (middle route of the South-to-North Water Diversion Project) for ensuring available water supplies in Beijing.ABSTRACT: Since its implementation in 2015, the Middle Route of the South-to-North Water Diversion Project (MR-SNWDP) has transferred an average of 45 billion cubic meters of surface water per year from the Yangtze River in southern China to the Yellow River and Hai River Basin in northern China, but how that supply is able to cope with droughts under different scenarios has not been explored. In this study, using the water demand for 2020 as the guaranteed water target, a Water Evaluation and Planning system was used to simulate available water supplies in Beijing under different drought scenarios. In the case of a single-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 16.7%; with the MR-SNWDP, this ratio reduced to 7.3%. In the case of a multi-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 25.3%; with the MR-SNWDP, this ratio reduced to 7.4% and domestic water supply was improved. Our research suggests that to prepare for multi-year drought in the Beijing area, the SNWDP supports increased supplies to the region that would mitigate drought effects. This study is, however, mostly focused on water supply provision to Beijing and does not comprehensively evaluate other potential impacts. Multiple additional avenues could be pursued that include replenishing groundwater, increasing reservoir storage, and water conservation methods. Further research is needed to explore the relative costs and benefits of these approaches.

“…A variety of perspectives, from specific to broad, have been used to answer this question. Some, such as Hu et al [24], discussed the economic impacts of the SNWTP as it applied to a single issue, in this case land subsidence. Others took a more comprehensive sustainability approach, either by estimating environmental costs and benefits (e.g., [25]) or by assessing ecosystem services of different kinds (e.g., [26]).…”

A Review of the Economic, Social, and Environmental Impacts of China’s South–North Water Transfer Project: A Sustainability Perspective

China's South-North Water Transfer Project (SNWTP) has the potential to transfer as much as 44.8 km 3 year −1 of water from the Yangtze River basin to the Yellow River basin. However, the SNWTP has not been assessed from a sustainability perspective. Thus, in this study we evaluated the SNWTP's economic, social, and environmental impacts by reviewing the English literature published in journals that are part of the Web of Science database. We then synthesized this literature using a Triple Bottom Line framework of sustainability assessment. Our study has led to three main findings: (1) whether the SNWTP is economically beneficial depends largely on model assumptions, meaning that economic gains at the regional and national level are uncertain; (2) the SNWTP requires the resettlement of hundreds of thousands of people and challenges existing water management institutions, suggesting possible social concerns beyond the short term; and (3) evidently large environmental costs in water-providing areas and uncertain environmental benefits in water-receiving areas together point to an uncertain environmental future for the geographic regions involved. Thus, the overall sustainability of SNWTP is seriously questionable. Although much work has been done studying individual aspects of SNWTP's sustainability, few studies have utilized the multi-scale, transdisciplinary approaches that such a project demands. To minimize environmental risks, ensure social equity, and sustain economic benefits, we suggest that the project be continuously monitored in all three dimensions, and that integrated sustainability assessments and policy improvements be carried out periodically.
