In Tarim River Basin (TRB), the retreat of glacier and snow cover reduction due to climate warming threatens the regional economy of downstream basins that critically depends on meltwater. However, the quantitative evaluation of its impact on multiple sectors of the socioeconomic system is incomplete. Based on compiled regional input–output table of the year 2012, this study developed a method to analyze the relationships between economic activities and related meltwater withdrawal, as well as sectoral transfer. The results show that the direct meltwater withdrawal intensity (DMWI) of agriculture was much higher than other sectors, reaching 2348.02 m3/10,000 CNY. Except for A01 (agriculture) and A02 (mining and washing of coal), the embodied meltwater withdrawal (EMW) driven by the final demand of other sectors was greater than direct meltwater withdrawal, and all sectors required inflows of virtual water (72.45 × 108 m3, accounting for 29% of total supply from cryospheric water resources) for their production processes in 2012. For sectors with high DMWI, improving water-use efficiency is an effective way to reduce water withdrawal. To some extent, the unbalanced supply of cryospheric water resources due to geographical segregation can be regulated by virtual water flows from water-saving to water-intensive sectors. Such decisions can affect the balance between socioeconomic development and environment conservation for long-term sustainability.

Beijing is located in a semiarid region, and water shortage is a common problem in the city. Along with the rapid increase in water demand, due to fast socioeconomic development and an increase in population, a shortage of water resources and a deterioration of the water environment have become obstacles to sustainable socioeconomic development in Beijing. In the long run, sustainable water resources management, water conservation, and completion of the south to north water diversion project will solve the problem. This paper introduces the water resources situation in Beijing; analyzes future water demand; and discusses the actions of water saving, nontraditional water resources exploitation, wetland construction, and water environment protection. The paper also explains the importance of the south to north water diversion project and the general layout of the water supply strategy, water distribution system, and methods to efficiently use the diverted water in Beijing.Key words: water resources, water supply, water saving, water recycling, water diversion.

Abstract. The accelerated consumption of water resources caused by the rapid increase in population and urbanization is intensifying the complex interactions across water resources, socioeconomic development, ecological protection, and food security (WSEF), which causes not only the imbalance between water supply and demand but also the vulnerability of both food and ecological systems. Therefore, identifying the dynamic coevolution and feedback process is one of the most crucial ways of achieving the goal of sustainable water use. In this study, we developed an integrated modeling framework to better identify the dynamic interaction and coevolution process of the nexus across WSEF systems in the context of sustainable water uses by coupling system dynamic (SD) model and multi-objective optimization model. The SD model is used to simulate both the dynamic interaction of each agent and the coevolution process of the whole nexus system by positive/negative feedback loops. The multi-objective optimization model is used to quantify the negative feedback loops of the SD model by generating the optimal scheme of different water users. Finally, the model uncertainty considering different weighting factors is analyzed. The framework is applied to the upper reaches of the Guijiang River basin, China. Results show that (i) the rapid economic growth increases the conflict between the water uses for socioeconomic development and ecological protection, intensifying the ecological awareness and resulting in more water shortages of socioeconomic and food agents, which is unable to support such rapid development. (ii) Once the economic growth rate decreases, water resources are able to support economic development with a decreased overload index and stable crop yield, which further contributes to water sustainability. (iii) The river ecological agent is the critical factor that affects the robustness of the model. (iv) The equal consideration of each water usage is the most beneficial to sustainable development. These results highlight the importance of water resources management, considering the tradeoffs across multiple stakeholders, and give a strong reference to policymakers for comprehensive urban planning.

Ecosystem vulnerability increases significantly when anthropogenic factors overlap with the effects of adverse climate change, which together negatively affect biodiversity and ecosystem functioning. According to ADB forecasts, the inflow to the lower reaches of the Amu Darya will decrease by 26-35% by 2050. The combined effect of higher water demand and lower inflow will increase the current water shortage - the annual water shortage will increase to 50% of the total demand. In connection with the projected changes, the current state of water resources of the Amu Darya river, as well as the need for the socioeconomic development of the region, the task of assessing the projected impact of climate change on the availability and quality of water resources becomes urgent.

Water resources management is increasingly important for sustainable economic and social development. A coherent division of the development stages is of primary importance for selecting and implementing related water resource management strategies. Using evolving supply–demand relationships, this paper proposes a framework that considers water development stages to present a series of dynamic relationships between water demand changes and overall economic development. The framework is applied to China to advance the understanding of how demand evolves at different stages of water resources development under specific socioeconomic circumstances, and of strategic choices in general. The case of China explains how water resources management has gradually improved during distinct socioeconomic development stages. It illustrates the varieties and effectiveness of water policies made to adapt to changing demand over the course of socioeconomic development. The framework can be potentially applied to other countries or regions to identify the development stage in order to select proper water management strategies.

Biodiversity conservation has been promoted in Nepal (within and outside protected areas) over the last three decades through relevant policies and legislations. The government has encouraged the participation of people through community user groups in managing the biodiversity and sharing the benefits. About 50 percent of the total revenue generated in protected areas is provided annually to such groups for resource management and community development activities. Forests are also managed by involving community users. Recently, attempts were made to manage biodiversity through an environmental impact assessment (EIA) process. The Nepal Biodiversity Strategy (2002) and Water Resources Strategy (2002), under implementation, recognise the role of EIA in mainstream biodiversity conservation in development programmes. However, biodiversity is under immense pressure due to infrastructure, water resources and socioeconomic development programmes and projects. His Majesty's Government of Nepal has made a policy commitment in its Tenth Plan (2002–2007) to carry out strategic environmental assessment (SEA) of development plans and programmes. Pursuant to this plan, an SEA has been carried out for the 25-year Nepal Water Plan. This plan is designed to, inter alia, promote the development of hydropower, irrigation, water-induced disaster management and drinking water programmes. This paper outlines the general understanding and knowledge of SEA in Nepal and examines how the SEA of the Nepal Water Plan addresses biodiversity aspects. It also outlines problems faced, and challenges and opportunities for strengthening SEA and its use to conserve biodiversity in Nepal.

Abstract. The total amount of water resources severely affects socioeconomic development of a region or watershed, which means that accurate quantification of the total amount of water resources is vital for the area, especially for the arid and semi-arid regions. Traditional evaluation of water resources only focused on the qualification of blue water, while the importance of green water was not fully considered. As the second largest river in China, the Yellow River plays an important role in socioeconomic development of the Yellow River basin. Therefore, the blue and green water resources in the upper Yellow River basin (UYRB) were evaluated by the SWAT model in this study. The results show that the average annual total amount of water resources in the UYRB was 140.5 billion m3, in which the blue water resources is 37.8 billion m3, and green water resources is 107.7 billion m3. The intra-annual variability of the blue water and green water is relatively similar during the same period. The higher temperature, the greater difference between the blue and green water. The inter-annual variability of the blue and green water shows that the trends in precipitation, blue and green water have a relatively similar characteristic. The spatial distribution of the blue and green water is characteristic with gradually decreasing from the northwest to the southeast, and the blue water around the main stream is greater than that in the other areas.

O semiárido nordestino é caracterizado historicamente como uma região onde o conflito pelo acesso e uso da água sempre esteve presente no cotidiano de sua população. Por uma série de fatores como: escassez hídrica crônica gerada pelo padrão climático da região, estruturação fundiária que privilegia apenas o desenvolvimento econômico dos grandes proprietários de terra e seus projetos agropecuários, ineficiência do estado em promover políticas públicas de gestão e conservação dos recursos hídricos, e intervenções pontuais de mitigação dos efeitos da seca, apenas em episódios extremos de déficit hídrico, causando pouca efetividade na solução do quadro de miséria e abandono da população. Diante do quadro histórico e socioeconômico de grandes prejuízos e degradação ambiental ocasionados pela seca e pela má gestão dos recursos hídricos no Ceará. Muitas pesquisas e projetos com o intuito de compreender o regime hidroclimático dos seus municípios surgiram como forma de entender as potencialidades e limitações das diferentes áreas, e dessa forma auxiliar a criação e a manutenção de políticas públicas de desenvolvimento socioeconômico e preservação ambiental. Diante deste contexto a pesquisa se propõe a realizar o balanço hídrico da Área de Influência do Açude Castanhão -CE, como uma ferramenta de gerenciamento e planejamento de recursos hídricos.Palavras-chave :Balanço Hídrico; Gestão; Recursos hídricos. ABSTRACTThe Northeastern semi-arid region is historically characterized as a region where conflict over access and use of water has always been present in the daily life of its population. For a series of factors such as: chronic water shortage generated by the region's climatic pattern, land tenure structuring that privileges only the economic development of large landowners and their agricultural projects, inefficiency of the state in promoting public policies for the management and conservation of water resources, and occasional interventions to mitigate the effects of drought, only in extreme episodes of water deficit, causing little effectiveness in solving the misery and abandonment of the population. In view of the historical and socioeconomic picture of great damages and environmental degradation caused by drought and the poor management of water resources in Ceará. Many researches and projects aimed at understanding the hydroclimatic regime of their municipalities have emerged as a way of understanding the potentialities and limitations of the different areas, and in this way help to create and maintain public policies for socioeconomic development and environmental preservation. In this context, the research proposes to carry out the water balance of the Area of Influence of the Castanhão-EC, as a tool for management and planning of water resources.Keywords: Hydric balance; Management; Water resources

Abstract. The increasing conflicts for water resources between upstream and downstream regions appeal to chronological insight across the world. While the negative consequence of downstream water scarcity has been widely analyzed, the quantification of influence of upstream water use on downstream water scarcity has received little attention. Here non-anthropologically intervened runoff (natural runoff) was first reconstructed in upstream, middle stream and downstream regions in China's 12 large basins in the 1970s to 2000s time period using the Fu–Budyko framework, and then compared to the observed data to obtain the developmental trajectories of water scarcity, including the ratio of water use to availability (WTA) and the per capita water availability (FI; Falkenmark Index) on a decadal scale. Furthermore, a contribution analysis was used to investigate the main drivers of water scarcity trajectories in those basins. The results show that China as a whole has experienced a rapid increase of WTA stress with surface water use rapidly increasing from 161 billion cubic meters (12 % of natural runoff) in the 1970s to 256 billion cubic meters (18 %) in the 2000s, with approximately 65 % increase occurring in northern China. In the 2000s, the increase of upstream WTA stress and the decrease of downstream WTA stress occurred simultaneously for semi-arid and arid basins, which was caused by the increasing upstream water use and the consequent decreasing surface water use in downstream regions. The influence of upstream surface water use on downstream water scarcity was less than 10 % in both WTA and FI for humid and semi-humid basins during the study period, but with an average of 26 % in WTA and 32 % in FI for semi-arid and arid basins. The ratio increased from 10 % in the 1970s to 37 % in the 2000s for WTA and from 22 % in the 1980s to 37 % in the 2000s for FI. The contribution analysis shows that the WTA contribution greatly increases in the 2000s mainly in humid and semi-humid basins, while it decreases mainly in semi-arid and arid basins. The trajectories of China's water scarcity are closely related to socioeconomic development and water policy changes, which provide valuable lessons and experiences for global water resources management.
