“…The cost-benefit analysis would be an effective way to evaluate cost savings (Fu et al ., 2016). To prevent saltwater intrusion in PRE, integrated water resources management has been one of the widely used, nonengineering measures to alleviate the water resource problems (Friesen et al ., 2017; Huang, Lou, and Li, 2016).…”

Accelerating sea level rise and intensifying extreme marine and weather events pose unprecedented challenges to coastal areas in the context of climate change. As a hotspot of marine disasters, Guangdong has been suffering from severe marine disasters including storms, flooding, coastal erosion, and saltwater intrusion in the last decades. It is essential for coastal management authorities to distinguish vulnerable areas and optimize coastal planning. To help identify the coastal vulnerability patterns of the Guangdong coast, the coastal vulnerability index was used based on integrated physical and socio-economic indicators including relative sea level rise, mean tide range, significant wave height, coastal slope, geomorphology, population, land use, and coastal gross domestic product. Each indicator was assigned five vulnerability classifications from very low to very high (1-5). Results show that about 36.7% of the coastline in Guangdong is highly vulnerable, of which 18.3% of the coastline is very highly vulnerable. About 63.3% of the coastline is in moderate to low vulnerability. In particular, the coastal areas in east of Zhanjiang, Maoming, Yangjiang, Zhuhai, Zhongshan, Guangzhou, west of Shenzhen, east Shanwei, and Chaozhou are more vulnerable to sea level rise, which calls for urgent planning and protective measures.

“…Although Macau was equipped with two storage reservoirs, namely the Macau Main Storage Reservoir (MSR) and the Seac Pai Van Reservoir (SPVR), it did not possess significant conventional water resources. As a result, a staggering 96% of its raw water supply heavily relied on mainland China; Macau's wastewater reuse policy was still in its initial stages and the rainwater use rate was only 3.4% in 2012 [31][32][33]. Currently, the water supply systems in Macao are divided into the West East Water Diversion System, the North System, and the South System.…”

Based on the driving force-pressure-state-impact-response (DPSIR) model, 19 indicators were selected to construct a comparison between Zhuhai and Macao, two adjacent cities at the estuary of the Pearl River in China, which have different development models and water resource sustainable development strategies. Factors that may affect the sustainability of water resources were screened and placed according to the relationships of the five subsystems in the DPSIR model, establishing a sustainable evaluation model for water resources in the two cities. The results analyzed by Principal Component Analysis and Entropy methods showed that (1) Zhuhai City was greatly affected by the driving force, while Macao was greatly affected by the state system from 2012 to 2021. (2) From the trend changes, it can be seen that, in recent years, the water resources of the two cities have been moving towards sustainable development, and the management and protection of water resources have achieved remarkable results. From the evaluation results, it can be seen that implementing urban water-saving activities, strengthening the proportion of environmental water conservancy, public measures in public investment, upgrading sewage treatment machinery to improve sewage treatment rates, and other measures can effectively improve the current situation of water resources in both regions. In the future, the Zhuhai and Macao cities may continue to face a series of water resource pressures brought on by socio-economic developments. Therefore, an active adjustment of the development of the measurement of controlling wastewater discharge and saving water resources was proposed, adhering to the direction of sustainable development, and ensuring the benign development of socio-economic conditions and the ecological environment. This study can provide data to support regional water resource security and policy formulation with different political systems.

“…For example, paper and pulp factories in China are directed to switch to total chlorine-free bleaching technologies. Wastewater reuse (Huang et al 2016) is another government policy in China with a target of establishing sewage treatment plants for 95% of their cities and 85% of their villages by 2020 (Eskeland and Jimenez 2019). 11th Five-Year Plan for Water Resources Development (Jiang 2009) is another 'command-and-Control' approach to control river pollution in China (Jiang 2009).…”

A range of technologies, strategies and policies have been implemented to improve water quality worldwide. This systematic review comprehensively appraises technologies, strategies, and water pollution control policies enacted in different countries worldwide between 2055 and 2021. Five databases, Web of Science, PubMed, Scopus, Google scholar and Library of Congress, were used for the search. After screening, a total of 86 eligible manuscripts were selected from 2119 documents for further analysis. Selected articles were divided into two categories: (1) articles introducing the strategies enacted for controlling water pollution based on different technologies, and (2) articles that focused on different policies and regulations to control water pollution in different countries. The results indicated that the most common technologies are Eco-Remediation, Aquatic Vegetation Restoration Technology, Bio-Manipulation Technology, Floating Aquatic-Plant Bed Systems, Wetlands Rehabilitation Technology and Adsorption Technology. And the current one is Atomic Layer Deposition (ALD). Most of these technologies are related to controlling industrial water pollution. Policies and regulations enacted in most countries are pertinent to the industrial and agricultural sectors. Adopting green industrialisation and farming, particularly elimination or limited use of pesticides, was reported as an effective action by governments to reduce water pollution. Overall, most policies enacted by governments can be divided into two general categories: (a) Prescriptive policies (b) Market-Based policies. Depending on the circumstances, these policies are implemented alone or jointly. In addition to the acceptance of international agreements to reduce water pollution by governments, safe agricultural practices, treating industrial waste before discharge play an important role in reducing water pollution.
