In complex socio-ecological systems, such as managing natural resources, human frames and mental models play a central role in deriving the system’s behaviour. Differences in stakeholder views and perceptions may impede the design and implementation of collective policies. Understanding stakeholder views and mental models is a pre-requisite for understanding decision making, improving communication, and eventually developing management policies that cater to the diversity of values and interests. Motivated by this premise, this research uses a cognitive mapping approach to examine the frames used by a group of water users with regard to managing available water resources. We focus on the Australian Capital Territory as a case study. Two different frames have emerged from the results: hard and soft. Differences in frames embody various perceptions about the problem definition, its causes, effective management strategies, and hence, responsibility attribution. The paper describes both frames and highlights those perceptions that may stand as barriers against sustainable management. These findings can be transferred to other arid and semi-arid areas. 相似文献

We have evaluated the extent of public concerns about water management in the Palestinian Territory (PT) through a survey of the main Palestinian newspaper over the last thirteen years divided in three periods: pre (1984–1987), during (1988–1991), and post national uprising period (1992–1996). The public concern in the PT about various water management aspects was clear and influenced by the prevailing political conditions indicating (1) poor concerns in the first and second period where full Israeli military control of the PT and harsh practices prevailed with relatively more emphasis on regional water issues and (2) extensive-strong concerns in the third period when the peace process started and a partial lift of some of the Israeli water practices took place, along with an increased freedom in expressing public concerns which was granted with more emphasis on local issues and problems. Lack and limitation of water available to Palestinians, alternative solutions, and water quality and pollution control constituted the overwhelming majority of the topics of concern to the public for the three periods studied. Palestinian concerns were always greater than regional ones for the three periods and all of the topics considered. Public concern in the PT about all other water management aspects was poor and negligible especially in the first two periods. A massive increase in public concern has been observed in the third period in which the public expressed their concern over most water management aspects, indicating a possible change in public attitude toward water and water management and reflecting the change of the political status by the start of the peace process and the signing of the peace agreements. 相似文献

Lack of water use data at the user scale is frequently noted in integrated water management and water demand modelling studies. This situation affects particularly mountain tourist areas, where high seasonal water demand related to the variation of temporary population are rarely documented. Irrigation is also a major water use in moutain territories but is not commonly measured. This paper proposes a framework for local-scale monitoring of seasonal water use behaviours and their territorial inprint. A monitoring strategy was developed to collect water demand data at thin spatio-temporal scales which were analysed using two concepts: (i) the water use regime, describing the dynamics of water uses throughout the year using normalised values, and (ii) the water use density, expressing the territorial footprint of a water use, in terms of unit area. This strategy was applied in the alpine tourist municipality of Montana (Switzerland). A two-year monitoring campaign of irrigation and drinking water uses was carried out combining in-field measurement (water metres) with interviews of water users. The temporal resolution of the collected water use dataset (bi-weekly, daily) was sufficient to assess the specific water demand patterns and the short-term water use peaks responsible for water stress in Alpine tourist regions. It provided the first irrigation monitoring in the area and a classification of drinking water data according to their spatial distribution, the type of building and the permanency of residents. The water use density method gives a new prespective on the spatial intensity of water uses, highlighting the importance of garden irrigation in Montana. Also, the water use regime method identified July as the period of water demand peaking. The monitoring of water uses at such thin temporal scale constitutes the necessary dataset for the creation of water balance models that accurately reproduce the effective water use behaviours. 相似文献

To manage water more effectively, a new approach is necessary, incorporating a balanced set of policies and in stitutional reforms. Its core is the adoption of a comprehensive framework for water management that recognizes the interactions among the elements of a river basin's ecosystem and incorporates cross-sectional and environmental considerations in the design of investments and policies. The new approach also calls for water to be treated as an economic good, for decentralized management and delivery stru ctures, greater reliance on pricing, and fuller participation by stakeholders. 相似文献

Our planet is getting thirstier and thirstier. Water scarcity has become an increasingly hard but urgent problem. The world's water situation engenders little optimism. About one quarter of the world's population is experiencing water scarcity. Moreover, water resources are unevenly distributed and extremely scarce in Africa and the Middle East. Water scarcity further incurs many international issues such as international conflicts, environmental refugees and disease caused by water pollution, which have made a more unstable world. To make contributions to solve the water problems, this study proposed a metric model to identify the ability of each country to manage water scarcity, and offered solutions to a country considered water over-loaded. In this paper, we developed our metric, Total Scarcity Metric, and divided it into Physical Scarcity Metric ( affected by environmental factors and population) and Economic Scarcity Metric ( affected by social factors other than population) by the two causes of water scarcity. This paper made some adjustments to an indicator we found widely-used in the literatures, and determine Physical Scarcity Metric based on it. Based on that result, Pakistan was chose as a sample region for further analysis, and Pakistan still has a long way to go. This model will prove to be advantageous for a region’s authoritative figures to consult with when in pursuit of obtaining a higher level of water resources allocation. It also can serve as a public rationale to support certain superficially incomprehensive judgments made by the administration. 相似文献

The method of material flux analysis is applied as an instrument for the early recognition of environmental problems in an urban region of developing countries. It is shown that, even with poor data quality and quantity, it is possible to apply the method in Tunja, an urban region in Colombia. With sensitivity analysis monitoring points are developed to attain 'early recognition' concerning changes in water quality and quantity in this region. Using the scenario technique it is shown that, owing to the low dilution capacity for sewage in the region, surface water cannot reach the quality of water at a natural state even if technical measures used in industrialized countries are taken. 相似文献

This work evaluates the potential for rainwater harvesting at the household level in the dry climate of Saudi Arabia. The amounts of rainwater that can be harvested in several cities in Saudi Arabia were estimated and it was found that a significant volume, exceeding 7.5 m3/100 m2 per year, can be harvested. The per cubic meter cost of harvesting rainwater was compared to that of producing desalinated water. It was found that harvested rainwater is cheaper to capture than desalinated water produced from renewable energy-driven desalination plants, but that is not the case for fossil fuel-powered desalination. The study also considered the effects of rainwater harvesting on mitigating floods and reducing greenhouse gas emissions. A cost-benefit analysis of installing rooftop rainwater harvesting systems in Saudi Arabia was performed. It revealed that it is economically feasible to harvest rain in cities including Hail, Jeddah, Taif, and Riyadh, while it is not recommended in the holy cities of Makkah, Medina, and Buraidah. 相似文献

This paper describes a water accounting system (WAS) that has been developed as an innovative new tool for strategic long-term water management. The WAS incorporates both disaggregated water use and availability, provides a comprehensive and consistent historical database, and can integrate climate and hydrological model outputs for the exploration of scenarios. It has been established and tested for the state of Victoria in Australia, and can be extended to cover other or all regions of Australia. The WAS is implemented using stock-and-flow dynamics, currently employing major river basins as the spatial units and a yearly time step. While this system shares features with system dynamics, learning is enhanced and strategic management of water resources is improved by application of a Design Approach and the structure of the WAS. We compare the WAS with other relevant accounting systems and outline its benefits, particularly the potential for resolving tensions between water supply and demand. Integrated management is facilitated by combination with other stocks and flows frameworks that provide data on key drivers such as demography, land-use and electricity production. 相似文献
