<正>美国纽约市是一个有800多万人口的现代化大都市,在历史上曾发生过多次因干旱缺水的情况。因此纽约市政府十分重视节水。纽约市的节水措施主要是两个方面:一是改造设备,防止漏水,减少用水;二是开展各种教育活动,动员全体市民自觉节水。它用声纳设备检查主要输水管道线路的漏水情况,每年检查1/3,  相似文献

Khorezm Province is located in the Amu Darya lowlands of Uzbekistan, where unsustainable use of irrigation water has led to the Aral Sea crisis. This study deals with the question of how farmers in Khorezm perceive water and its management and how this facilitates or prevents water conservation, or “water saving,” in irrigated agriculture. To answer this from the perspective of the water users, we apply Schütz's lifeworld concept to the study of natural‐resource management, thereby reconstructing the water lifeworld of Khorezmian farmers. We present the spatial and temporal boundaries of the water lifeworld; the different types of water, people, and land that farmers distinguish; and the institutions water management is based on. The analysis shows that religious values and the risk of being fined for water wasting facilitate water saving. However, the following barriers to water saving dominate farmer practices: (1) storage of saved water is not possible, (2) using much water creates social capital, (3) perceived water needs exceed the geographical realities, (4) the term “water saving” is not in use, and (5) farmers believe that water management is the state's responsibility. We conclude that water saving should be facilitated by environmental education, a strengthening of the water‐inspection department Uzsuvnazorat, and the creation of decentralized storage options.  相似文献

The post‐1980s have seen increasing struggles over rights to water. Water rights have involved intense protests and campaigns against privatization of water including bottling of water and advocacy for citizens control of water. We review scholarly work to focus on four main aspects: the complexities intertwining globalization processes, the state, and water rights; collective ownership of water resources; peoples’ participating in managing and using water; and the campaigns against privatization which have emerged in both the developing and developed world in different ways. The conclusion calls for adopting a social movement lens to examine the struggles for water rights by providing some lead research questions around the macro and micro level theoretical approaches.  相似文献

Water resources carrying capacity is a foundational topic in water resources security strategic study and the foundational measurement of water resources security. Water resources constrain the scale and quality of social and economic development in many water shortage cities and regions. Thus, the management via dynamic water resources prediction is a key for the overall city strategic planning. In this study, an integrated dynamic model of water consumption was developed using system dynamics (SD) and based on water resources carrying capacity (WRCC) theory.  相似文献

The world is currently confronting two water crises, a developmental crisis concerning populations who lack access to water and an environmental crisis regarding water scarcity and freshwater resource depletion. Are we as academics addressing the complexity of these issues? Using network analysis of over 5,000 articles that address water development and water scarcity, I generate a co-citation network to identify the overlap between development and environmental water literatures in academic journals. The results suggest that the development literature only has a 6.28 percent overlap with the environmental literature and the environmental literature has a mere 1.92 percent overlap. Overall, this research suggests that there is an extreme lack of academic articles that address water scarcity and water development concurrently. Until we as an academic community become more nuanced in our studies of water, we will lack a full understanding of how to solve these seemingly contradictory problems. I conclude by drawing on critical Marxist and “Frankfurt School” perspectives to explain this apparent disconnect.  相似文献

Characterized as a “wicked” problem, water shortage in the American West will soon become a reality—due to increasing population, climate change, and decreased flows. Concurrently, water‐centered technologies such as hydraulic fracturing and directional drilling have facilitated the rapid and widespread growth of unconventional oil and gas (UOG) production in the United States. Water markets are increasingly touted as the best, most efficient, and fairest mechanisms for allocating vital and scarce resources. Yet this contention is largely unexplored at the food‐energy‐water nexus, particularly from an environmental justice perspective—where equitable water access for all users is a central concern. We utilize a case study in Colorado's South Platte basin based on 41 in‐depth interviews to show: (1) distortions created in regional water markets as wealthy UOG operators participate in them and (2) ways in which access to water markets becomes blocked for smaller, newer, or water‐poor water users. We also highlight how UOG producers’ presence may inhibit the formation of alternative systems for water exchange. Thus, the participation of UOG operators in Colorado's water markets appears to drive environmental injustice and increased inequity at the food‐energy‐water nexus, rather than facilitating fair or efficient access to water for all users.  相似文献

Rising urban and environmental demand for water has created growing pressure to reallocate water from traditional agricultural uses. The evolution of water markets has been more complicated than those for other resources. In this paper, we first explain these differences by examining water rights and regulatory issues. Second, we place our research in the context of the economics literature on water marketing. Third, we present new, comprehensive data on prices and the extent, nature, and timing of water transfers across 12 western states from 1987 to 2005. We find that prices are higher for agriculture-to-urban trades versus within-agriculture trades, in part, reflecting the differences in marginal values between the two uses. Prices for urban use are also growing relative to agricultural use. Markets are responding in that the number of agriculture-to-urban transactions is rising, whereas the number of agriculture-to-agriculture transfers is not. Further, there is a shift from using short-term leases to using multiyear leases of water and permanent sales of water rights. This pattern underscores the need to consider the amounts of water obligated over time rather than examining only annual flows in assessing the quantities of water traded as is the common practice in the literature. Considering water obligated over time, termed committed water, we find significantly more is transferred and the direction of trading is different than if the focus is on annual flows. Finally, the data reveal considerable variation in water trading across the states. ( JEL Q2, N5, L5, K3)  相似文献
