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.

Water Resources Utilization

This paper analyze the relativity of water resources utilization in Minqin and social economic sustainable development adopting optimal multiple regressions. The results show that: 1There is remarkable correlation between the economic growth and the demand of water resources. On condition that the sustainable development of economy is satisfied, the growth of rural population is a huge pressure on water resources. It is an appropriate measure to coordinate the environmental protection and social economic development that reducing the consumption of water for rural population or accelerating the process of urbanization and developing forestry and animal husbandry. 2) Increasing urban population and developing industry and modern farming can promote our economic growth at the same time reduce the pressure on water resources significantly. 3) 97.5% of the variation in the total water requirement of Minqin is caused by two variables animal husbandry output value and rural population. So the major routes of rational utilization of water resources and the sustainable development of social economy in Minqin are reducing the consumption of water for rural population constantly or accelerating the process of urbanization and optimizing animal husbandry industry further.

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 are the key factors affecting the sustainable development of inland river irrigation districts. The establishment of a water resources management model is helpful to realize the coordinated development of water, society, and ecology. Aiming at the contradiction of water use and ecological vulnerability, this study was based on the method of complex adaptive system (CAS) theory, and an agent-based modeling (ABM) method was adopted. Taking Huaitoutala irrigation district as the research object, a water resource management model considering ecological balance was established, with the water resources potentially tapping in the source area as an effective constraint. This study took 2016 as the datum year; the water consumption and comprehensive benefits of four water-saving irrigation scenarios in different characteristic years were simulated and optimized under the conditions of the current water supply and 10% and 15% potential water resources tapping. The results showed that the model considering the behavior and adaptability of the agent can well optimize and simulate the water use in the irrigation district. Under the application of water resources potential tapping and high-efficiency water-saving technology; the water utilization efficiency (WUE) of the irrigation area has been significantly improved. The comprehensive benefits of the irrigation district increased the proportion of ecological water, which was conducive to the sustainable development of the irrigation district and the ecological protection of inland rivers.

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.

Abstract Water resources in the Middle East region are becoming scarce, while millions of people already do not have access to adequate water for drinking and sanitary purposes. Water resources depletion has become a significant problem in this region that is likely to worsen. Current research by remote sensing analysis indicates a descending trend of water storage in the Middle East region, where agriculture plays a crucial role in socio-economic life. This study introduces an approach quantifying water depletion in the Middle Eastern countries, which are being challenged in the management of their water resources. Furthermore, this paper presents results of a survey assessing the status of water use and supply in Middle Eastern countries and outlines some potential remedies. Specifically, Iran's water use is evaluated and compared with its neighbors'. The water equivalent anomaly (WEA) and total water storage (TWS) depletion are two indexes of water scarcity calculated for Middle Eastern countries surveyed herein. Our analysis reveals that Lebanon, Syria, Iraq, and Iran are countries with very negative water scarcity indexes. These estimates prove that international cooperation is needed to manage available regional water resources and reverse depletion of natural water sources. It is demonstrated herein that virtual water trade can help remediate regional water shortage in Middle Eastern countries.
