The sustainability of regional water resources has important supporting data needed for establishing policies on the sustainable development of the social economy. The purpose of this paper is to propose an assessment method to accurately reflect the sustainability of regional water resources in various areas. The method is based on the relative entropy of the information entropy theory. The steps are as follows. Firstly, the pretreatment of the evaluation sample data is required, before the relative entropy of each standard evaluation sample and evaluation grade (SEG) is calculated to obtain the entropy weight of each evaluation index. After this, the entropy weighted comprehensive index (WCI) of the standard evaluation grade sample is obtained. The function relation between WCI and SEG can be fitted by the cubic polynomial to construct the evaluation function. Using the above steps, a generalized entropy method (GEM) for the sustainable assessment of regional water resources is established and it is used to evaluate the sustainability of water resources in the Pingba and Huai River areas in China. The results show that the proposed GEM model can accurately reflect the sustainable water resources in the two regions. Compared with the other evaluation models, such as the Shepherd method, Artificial Neural Network and Fuzzy comprehensive evaluation, the GEM model has larger differences in its evaluation results, which are more reasonable. Thus, the proposed GEM model can provide scientific data support for coordinating the relationship between the sustainable development and utilization of regional water resources in order to improve the development of regional population, society and economy.

Water Resources Utilization

Water is an important factor of production contributing to all sectors and regions in the world. With the rapid development of the economy and the increase of population, the water crisis is becoming more and more serious, and will become an important obstacle to the sustainable development of society. It is particularly important to evaluate the sustainability of water resources utilization. Based on the analysis of the regional water resources utilization characteristics, this paper takes 31 provinces in mainland China as the research object and comprehensively evaluates the regional water resources’ sustainability from the aspects of hydrology, environment, economy and technology. The results show: From the regional perspective, the regionalization of China’s various indexes is obvious, the hydrological and environmental indexes in western regions are significantly higher than that in eastern regions; while the economic index in eastern regions is higher than that in western regions. From the time perspective, from 2010 to 2015, the sustainable development of water resources in seven provinces showed an increasing trend. Zhejiang changed from “Good” to “Excellent” and Hubei, Hunan, Guangxi, Sichuan, Guizhou and Xinjiang all had slight growth. There are six provinces which show varying degrees of decline, of which Liaoning changes from “Excellent” to “Medium”, Beijing, Hebei, Jilin, Guangdong, Hainan also had a slight decline; the rest of the provinces did not change, Qinghai and Chongqing have been maintained as “Excellent”. Taken together, the western regions of China have significant advantages in terms of quantity and quality of water resources, but its water use efficiency is low. However, the economic development in the eastern regions is rapid with high efficiency of water use, but there are some serious problems such as water resources insufficiency and river pollution.

Based on the regulating principles, the modes of joint regulation and storage of surface water and groundwater in Rushan River Basin are simulated using multi-objective programming method. The study suggests two modes as “two dry years and one normal year” and “four dry years and one wet year”. The results indicate the guarantee rates of water supply are improved, with increasing the exploitation quantity in dry years and the recharge in wet years. The study provides a strong guarantee for water resources regulation and promotes the sustainable development of regional water resources.

Despite the ‘immense’ water resources available, Nepal has not been able to transform this abundance of water resources into desired economic growth and societal welfare. This paper attempts to analyze the reasons for such incessant challenges that loom over water resources development in Nepal. This paper finds that it is not the resource that limits the development of water resources, but the approaches and wishes that are framed on the foundation of persistent myths. Analyzing those myths, this paper highlights the realities in water resources management of Nepal, and suggests that without dismantling the existing myths, the sustainable development of water resources seems limited.HYDRO Nepal JournalJournal of Water, Energy and Environment Issue: 23Year: 2018

Water resources are central to the achievement of all the Sustainable Development Goals, and should be viewed as a crosscutting connector - not a sector. The water community should do more to get outside its safety zone and work with all water-related sectors. The SDG 6 IWRM Support Programme is assisting countries to use water as a connector between their SDG targets.

As rare earth resources are indispensable raw materials for modern society, they have become strategic global reserve resources. Even though China is the world’s largest producer and exporter of rare earth, the industry has low efficiency and severe problems with over-exploitation and environmental pollution; therefore, there needs to be a greater focus on the sustainable exploitation of rare earth resources. This paper establishes an innovative evaluation index system for the sustainable development of China’s rare earth resources from six main aspects; economic development, social progress, environmental protection, technological innovation, rare earth development and utilization, and rare earth protection in which the indicators are assessed using an entropy method. Grey correlation analysis was used to evaluate China’s rare earth sustainable development level from 2006–2016, from which it was found that sustainable development was poor from 2006–2010 and marginally better from 2011–2016. The main factor affecting rare earth sustainable development in China was found to be the lag in the development of environment protection system and rare earth protection system. Policy recommendations for improving China’s rare earth protection, environmental protection, and technological innovation are proposed to guide government regulations and assist rare earth industry personnel.

Limited water resources have become a serious problem in recent decades. Based on previous research results, this article develops an index system to evaluate sustainable water resource development that includes a water resource condition system, a water resource development and utilization system, a water resource protection and management system, and a socio-economic system. A measurement model is then constructed based on a principal component analysis (PCA) -entropy weights-weighted average method to optimize the evaluation index system for dimensionality reduction, to assign weights to the principal component factors, and allow for a comprehensive evaluation of water resource sustainability. The measurement model is applied to an empirical analysis of sustainable water resource development in Sichuan Province from 2008 to 2017, from which it is found that coordinated sustainable regional water resource and social economic development can be achieved through rational exploitation, efficient utilization, and environmental water pollution control. This research could provide a reference for regional sustainable development of water resources and policy developments.

Due to the complexity and diversity of the issue of sustainable island development, no widely accepted and applicable evaluation system model regarding the issue currently exists. In this paper, we discuss and establish the sustainable development indicator system and the model approach from the perspective of resources, the island environment, the island development status, the island social development, and the island intelligence development. We reference the sustainable development theory and the sustainable development indicator system method concerning land region, combine the character of the sustainable island development, analyze and evaluate the extent of the sustainable island development, orient development, and identify the key and limited factors of sustainable island development capability. This research adopts the entropy method and the nonstructural decision fuzzy set theory model to determine the weight of the evaluating indicators. Changhai County was selected as the subject of the research, which consisted of a quantitative study of its sustainable development status from 2001 to 2008 to identify the key factors influencing its sustainability development, existing problems, and limited factors and to provide basic technical support for ocean development planning and economic development planning.

In 1957, the four lower Mekong River states jointly organized the development of the basin and established a legal regime that has spanned five decades of cooperation. In 1995, Cambodia, Lao PDR, Thailand and Vietnam concluded the Agreement on the Cooperation for the Sustainable Development of the Mekong River Basin and formed the Mekong River Commission, which has been lauded as the most progressive of river institutions and a model for the world. At the core of the 1995 Mekong Agreement is the concept of sustainable development. Guided by this sustainable development paradigm, the Lower Mekong River Basin states attempt to balance the maintenance of water quantity with protection of water quality, and agree to cooperate and use the Mekong's water resources in a manner in which the river system's environmental conditions and ecological balance are conserved and maintained. However, development of the Mekong and its tributaries has rendered the efficacy of the Mekong legal regime to support holistic water resources management questionable. More than ten years of experience has shown that there are aspects of the 1995 Mekong Agreement that should be strengthened in order to secure the environmental, economic and social benefits that it promises.

Enterprise sustainable development emphasizes coordination of the development of economy, environment and society. The life cycle cost based on the sustainable development controls the engineering cost as well as environmental pollution and damage. The thermal power plant burns large amount of fossil fuels and discharge pollutants which cause serious pollution. Therefore the pollution control and ecological conservation make up important parts of construction and production cost, both of which are key parts of life cycle cost. This paper uses analytic hierarchy process and fuzzy comprehensive evaluation to estimate the life cycle cost and helps the enterprise to make social or temporal comparison and potentiality exploitation and to improve its sustainable development capability.
