Infrastructure for Sustainable Development and Management of Water Resources

Tibet, known as the “roof of the world” in China's southwest border region, is not only rich in water resources, but also regarded as an important national energy reserve base. However, on a global scale, Tibet is also one of the few places in the world that faces the challenge of water scarcity. In order to cope with this challenge, it is necessary to deeply understand and grasp the connotation, essential characteristics and basic requirements of the concept of ecological civilization, and on this basis, combined with the current situation of water resources in Tibet, analyze the existing problems and put forward improvement measures in the light of the concept of ecological civilization, to promote the sustainable development and management of water resources in Tibet. As one of the core elements of ecological civilization construction, the protection and rational utilization of water resources are directly related to the stability of the ecological environment and the sustainable development of human society. Therefore, it is necessary to curb water pollution from the source and strengthen the protection of water environment. In view of the shortage of water resources in Tibet, it is necessary to scientifically plan and manage water resources, rationally allocate water resources, and improve the efficiency of water resources utilization. At the same time, it is also necessary to use modern scientific and technological means, such as remote sensing technology and big data analysis, to carry out real-time monitoring and management of water resources in Tibet to better cope with the challenge of water shortage. Finally, it is necessary to adhere to the concept of harmonious coexistence between man and nature, respect nature, adapt to nature, and protect nature, in order to achieve the goal of harmonious coexistence between man and water, man and nature. In general, through the in-depth study of water resources in Tibet, we can better understand the connotation, essential characteristics and basic requirements of the concept of ecological civilization, so as to propose more scientific and reasonable improvement measures to promote the sustainable development and management of water resources in Tibet and to realize the harmonious coexistence between human beings and nature.

The quantitative and qualitative evaluation of water, land and biotic resources in the inland river basins is important in the arid zone. Analysis of the exploitation potential of water resources and the environmental changes through water development can help people in the sustainable development and management of water resources within the basin. Water resources development has affected the scale of oasis establishment in the middle reaches and the existence of lower-reach oases in the Hei River basin. Exploitation and utilization of water resources at the present stage should bring about a harmonic relation between economic development and the ecological environment in the whole basin. The whole area should be considered as an entirety to adopt feasible engineering and administrative measures such as strengthening the protection of water resources in upper streams, macro-control of water consumption and implementing water-saving measures in middle and lower reaches, quantitatively managing and allotting water resources in accordance with regional conditions and adherence to comprehensive rehabilitation. Thus, economic, environmental and social benefits of water resources can be enhanced.

Water resources are the basic resources on which people depend for survival. They play an indispensable role in the procedure of modern economic society and also important links in the construction of ecological civilization. With the continuous acceleration of the industrialization process, the problem of rapid population increased cannot be furthermore underestimated. The healthy water resources have increasingly become a prerequisite for sustainable economic and social development, and it is imperative to strengthen the sustainable development and management of water resources. Therefore, including the existing problems in the management of water resources, and propose further development strategies, which provides feasible references for promoting the rational use of environmental resources and protecting China’s river basins.

The development of South Korean water resources has been heavily concentrated in a few areas, corresponding to regions that have experienced economic growth. The resulting competition for the resource is leading to calls for more equitable water distribution. The objective of this study is to evaluate water stress areas for sustainable water resources management. For this, a spatially distributed water stress index that accounts for climate variability at intra- and inter-annual time scales is developed and applied to South Korea to better understand the water allocations, and the subsequent water stress. Water demand (household water, industrial water, agricultural water, and livestock water) and water supply (precipitation use, reservoir use, stream use, and underground water use) estimates based on the period 1973–2009 were used to compute the normalized deficit index (NDI) and normalized deficit cumulative (NDC) for each hydrologic basin. Water stress was assessed for each of the four decades (1973–1982; 1983–1991; 1992–2000; 2001–2009). The overall water stress has decreased in 2000–2009 compared to 1973–1982 because of water infrastructure development. However, while the risk of water stress was low in the Han River basin, the Nakdong River was found to be very vulnerable to water stress. It was possible to investigate where water management strategies are needed for the sustainable development of South Korean water resources.

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.

It is important to maintain the sustainable development of water resources. Objective assessment on water resource carrying capacity (WRCC) is beneficial to the formulation of scientific and reasonable water management practices. In view of the problem that evaluation indicators of WRCC cannot describe the fuzziness and randomness, a cloud model was introduced into regional WRCC assessment. This study selected a typical karst area (Guiyang) as the research object to study WRCC by using cloud model with combination weighting method. WRCC was assessed from the following five dimensions: water environment subsystem, social subsystem, economic subsystem, ecological subsystem, and humanities (water resource management and policy regulation) subsystem. In addition, evaluation results after normalizing all of indicators data were also calculated. And these two kinds of evaluation results were compared with that of technique of order preference similarity to the ideal solution (TOPSIS), finding that evaluation results of cloud model were consistent with that of TOPSIS method. The cloud model realizes the transformation from qualitative evaluation to quantitative evaluation, which overcome insufficiencies of traditional evaluation methods in considering fuzziness and randomness. Results showed that during the period of 2008-2017, the state of WRCC in Guiyang was improving year by year, increasing from the serious overload carrying capacity level in 2008 to the strong carrying capacity level in 2017 (serious overload-overload-critical-weak carrying capacity-strong carrying capacity). However, some certain evaluation indicators are still in danger situation, such as population natural growth rate and use of the fertilizer per unit cultivated area, which needs to be further enhanced and improved. Moreover, the contradiction among economic development, population growth, and water resources is becoming increasingly apparent. To ensure the effective utilization of water resources in Guiyang, reasonable policies and measures should be formulated and put into effect. Research results could provide certain reference for the sustainable development of regional water resources.

SUMMARY The notion of sustainable development in the context of water resources is discussed. Facing the increasing pressures — population growth with consequences for settlements and production of food and fibre, and human aspirations to better living standards — the business-as-usual approach to water development and management cannot he globally sustainable. The need for curbing water demands and for ‘doing more with less’ are gaining growing recognition in our increasingly thirsty planet. An integrated approach to freshwater resources is needed, based on the perception of water as a natural resource, part of the ecosystem, and an economic and social good. It is discussed how hydrological extremes jeopardize sustainable development. Sustainability-related properties of drought and flood preparedness and mitigation measures are reviewed. Even if the term ‘sustainable development’ has been typically used in a qualitative sense, in order to compare how different options (e.g. flood protection alternatives) fare with regard to sustainable development, one needs at least rough quantitative measures. A sample of relevant indices is reviewed. It is advocated that hydrological observations should be recognized as an essential component of sustainable development and management of water resources.

Integrated Water Resources Management (IWRM) is a basin-wide approach of water resources management in a sustainable and balanced way considering social equity, environmental sustainability and economic effi ciency (CDRI 2008; GWP and INBO 2009; Pollard and Toit 2011). It is increasingly seen as an important tool for sustainable use of water resources for development (CDRI 2008) acknowledging linkages in scale and across disciplines and adoption of iterative and adaptive approaches (Pollard and Toit 2008). For the successful implementation of IWRM, and sustainable water resources development and management, Global Water Partnership (GWP) has proposed “effective water governance” to be placed at different levels of society (Rogers and Hall 2003; K’Akumu 2007). It identifi es accountability, participation, predictability and transparency as key elements in good governance. The Global Water Partnership defi nes water governance broadly as “the range of political, social, economic and administrative systems that are in place to regulate the development and management of water resources and provision of water services at different levels of society” (K’Akumu 2007). Asian Development Bank (ADB) describes governance as “promoting sound development management in which power is exercised in the management of a country’s social and economic resources for development” (ADB 1995). Good governance is also considered as to comprise the rule of law, effective state institutions, transparency and accountability in the management of public affairs, respect for human rights, and the participation of all citizens in the decisions that affect their lives (CDRI 2008). According to Rogers and Hall (2003), creating an institutional and administrative framework is one of the key elements of governance within which various actors with different interests can discuss and agree to co-operate and coordinate their actions. According to Kaufmann et al. (2000), the most important and least studied aspects of institutional change is the context of governance in which water resource organizations operate. In this backdrop, this chapter looks into the role of institutions and governance structure for river basin management options, which are being implemented in Nepal.

(eds.), Advances in Water Resources, Coastal Management, and Marine Science Technology. Journal of Coastal Research, Special Issue No. 104, pp. 130–135. Coconut Creek (Florida), ISSN 0749-0208.According to the problem that the use and development of water resources cannot be lack of ecological protection as a basic idea to ensure the goal of protecting the ecology and saving water. Therefore, in order to better study the environmental protection and utilization of water ecology, this paper makes a simple discussion on the sustainable development and utilization of water resources based on the background of ecological environment protection and the Marxist ecological theory, in the theory and algorithm of water footprint On the basis of the research, the current status of water ecology in a county town and the utilization of water resources were studied. It was found that the local water resources utilization rate was low and the water ecological environment pollution was serious. Specific suggestions were put forward from the perspectives of water resources management and water ecological management. For the reference of relevant personnel. After research, it is proposed that the establishment of the overall framework of the water ecological compensation mechanism to rationally develop and utilize water resources, and increase the intensity of sewage treatment can help the sustainable development and utilization of water resources. This has a theoretical and theoretical basis for revealing the root causes of China's ecological crisis. Practical significance.

A concept of sustainable development has become a major concern in international debate on water resources development and environmental conservation. Although sustainable water resources development and management takes a significant amount of concern in the development research, its applicability has not been insufficient in practices. The purpose of this study is to address a definition of sustainable water resources development and management and to illustrate relevant indicators. The study has also attempted to develop localized indicators hence to assess an availability of water resources development and management and to evaluate the water resources in Korea with the indicators which have been developed in other countries.

Water resources are important in large basins which are important places for human habitation and industrial and agricultural development. The background of editing this thematic issue was introduced and the general water resources situation and water quality status in four major large river basins in the Asian and African continents were briefly summarized to give readers general pictures of water resources development and management in these basins, and these large river basins are the Yellow River Basin, the Yangtze River Basin, the Indus Basin, and the Nile Basin. The thematic issue papers were classified into four clustered topical categories, and the main points of the papers in this thematic issue were summarized. Finally, the perspectives of future sustainable water resources development and management in large river basins were proposed.

Water resources are a very important issue in the Global Risk 2015 published by the World Economic Forum. The research objective of this study was to construct a Water Poverty Index (WPI) for islands. The empirical scope of this study was based on Kinmen Island in the Taiwan Strait, which has very scarce water resources. Kinmen has a dry climate with low rainfall and high evaporation. Therefore, the Kinmen area is long-term dependent on groundwater resources and faces serious water resource problems. This study used the WPI to examine various issues related to water resources. In addition, this study selected several main indicators and performed time series calculations to examine the future trends of water resources in Kinmen. The results show that the overall water resources of Kinmen are scarce. To ensure sustainable development of water resources in Kinmen, policies to improve water scarcity, such as water resource development, water storage improvement, and groundwater control, should be researched. The research results of this study can be used as a reference for government agencies in formulating and revising water resources to achieve the sustainable development of island-type water resources.
