Title: A Water Evaluation and Planning-based framework for the long-term prediction of urban water demand and supply Author(s): Arfa Saleem; Imran Mahmood; Hessam Sarjoughian; Hasan Arshad Nasir; Asad Waqar Malik Abstract: Increased usage and non-efficient management of limited resources has created the risk of water resource scarcity. Due to climate change, urbanization, and lack of effective water resource management, countries like Pakistan are facing diffi- culties coping with the increasing water demand. Rapid urbanization and non resilient infrastructures are the key barriers in sustainable urban water resource management. Therefore, there is an urgent need to address the challenges of urban water management through effective means. We propose a workflow for the modeling and simulation of sustainable urban water resource management and develop an integrated framework for the evaluation and planning of water resources in a typical urban setting. The proposed framework uses the Water Evaluation and Planning system to evaluate current and future water demand and the supply gap. Our simulation scenarios demonstrate that the demand–supply gap can effectively be dealt with by dynamic resource allocation, in the presence of assumptions, for example, those related to population and demand variation with the change of weather, and thus work as a tool for informed decisions for supply management. In the first scenario, 23% yearly water demand is reduced, while in the second scenario, no unmet demand is observed due to the 21% increase in supply delivered. Similarly, the overall demand is fulfilled through 23% decrease in water demand using water conservation. Demand-side management not only reduces the water usagein demand sites but also helps to save money, and preserve the environment. Our framework coupled with a visualiza-tion dashboard deployed in the water resource management department of a metropolitan area can assist in water plan-ning and effective governance.

Title: Achieving sustainable soil and water protection: The perspective of agricultural water price regulation on environmental protection Author(s): Lichen Chou; Jie Dai; Xiaoyan Qian; Aliakbar Karimipour; Xuping Zheng Abstract: With the development of Chinese economy, more and more attention has been paid to environmental protection, the implementation of water price policy affects economic and environmental changes in China. This paper analyzes the impact of water price policy on agricultural land use and the scale of water pollution discharge in 240 cities in China between 2001 and 2017, by including data from China Urban Statistical Yearbook and China Land & Resources Almanac. The theoretical analysis of this study indicates that the optimal scale of pollution depends on the local initial endowment, economic investment capital and the marginal cost of environmental pollution caused by government’s economic activities. Furtherly, the economic activities have a worsening impact on environmental pollution, but when the government implements environmental protection and water price policy measures in response to environmental pollution caused by economic activities, it has a significant impact on the decline in the scale of pollution. The government has promoted the pollution suppression model in the formulation of water prices, which has internalized the external cost of pollution in economic activities and can effectively reduce the scale of agricultural water pollution discharge.

Title: Current Situation of Water pollution in Vietnam and Some Recommendations Author(s): Huynh Tan Hoi Abstract: The problem of environmental pollution not only directly affects the health and life of people but also affects the offspring and offspring. Over the years, the legal system of environmental protection and environmental management system has been increasingly strengthened, but many aspects still have not met the requirements of reality. Environmental pollution in general and water pollution in particular are becoming more and more serious. The paper addresses the current situation of water pollution in Vietnam based on relevant journal documents. A number of solutions have also been proposed to contribute to making our earth a more livable place.

Title: Estimating surface water and vadose water resources for an ungauged inland catchment in Vietnam Author(s): Liem Duy Nguyen; Phuong Dong Nguyen Dang; Loi Kim Nguyen Abstract: This study aimed to assess water resources for the La Vi catchment, an ungauged inland basin in Vietnam. An Internet of Things-based automatic meteorological station has been installed in the catchment to record hourly weather data from 2016. By comparing water level observations with limited discharge measurements, discharges from November 2015 to February 2018 were calculated at Tan Hoa bridge using the slope-area method. The Soil and Water Assessment Tool was calibrated and validated for the wet season of 2015 and 2017, respectively, using the previously calculated water discharges. Statistical measures including Nash–Sutcliffe index, percent bias, and coefficient of determination indicated the satisfactory performance of the model in simulating water discharge on daily time steps during both periods. The results of the water resources assessment in the catchment showed that the annual average of blue water flow, green water flow, and green water storage reached 1,596.50, 371.13, and 15.36 mm, respectively. The blue water flow reached a higher value in the center of the catchment. Meanwhile, the high-value areas of green water flow and green water storage were in the western upstream and the riverside downstream. These findings could provide a valuable scientific foundation for sustainable watershed management.
