Abstract:

Increasing urbanization has resulted in an uneven distribution of population, industries, and water in urban areas; thus, imposing unprecedented pressures on water supplies and water pollution control. These pressures are exacerbated during the periods of drought and climatic uncertainties. The purpose of this paper is to summarize emergence of water reclamation, recycling and reuse as a vital component of sustainable water resources in the context of integrated water resources management in urban and rural areas. Water quality requirements and health and public acceptance issues related to water reuse are also discussed. Reclaimed water is a locally controllable water resource that exists right at the doorstep of the urban environment, where water is needed the most and priced the highest. Closing the water cycle loop not only is technically feasible in agriculture, industries, and municipalities but also makes economic sense. Society no longer has the luxury of using water only once.

Abstract:

Urban water is facing the challenges of both scarcity and water quality deterioration. Consideration of nonconventional water resources has increasingly become essential over the last decade in urban water resource planning. In addition, rapid urbanization and economic development has led to an increasing uncertain water demand and fragile water infrastructures. Planning of urban water resources is thus in need of not only an integrated consideration of both conventional and nonconventional urban water resources including reclaimed wastewater and harvested rainwater, but also the ability to design under gross future uncertainties for better reliability. This paper developed an integrated nonlinear stochastic optimization model for urban water resource evaluation and planning in order to optimize urban water flows. It accounted for not only water quantity but also water quality from different sources and for different uses with different costs. The model successfully applied to a case study in Beijing, which is facing a significant water shortage. The results reveal how various urban water resources could be cost-effectively allocated by different planning alternatives and how their reliabilities would change.

Abstract:

The population in urban areas is growing rapidly; from 30% in 1950 to about 50% at the turn of the century. In 35 years time, the number of large cities (greater than one million) will double and the population living in them will triple. Most large cities are already facing water supply problems and these will increase in the future. Water reclamation for nonpotable reuse for urban irrigation, industry, toilet-flushing, cooling, construction etc. can reduce the demand on limited fresh water resources. Many urban areas around the world have already used this approach to meeting problems of increased water demand.

Abstract:

The world wide water crisis we are facing nowadays is no longer how to acquire new water resource, but rather how to manage the available water resource. The water resource management practices in China are still under the guidance following conventional mindset and compliances. It was yet brought up to people’s attention that water resource planning is a crucial element of urban planning, not to mention the effort that should be spent in investigating and exploring the potential value of water to economy, esthetics and social development. This paper introduced the practices of Singapore government in managing its local water resources, i.e. recovery of the polluted water environment in its early years, integrated planning of catchment and reservoirs for stormwater storage, acquiring new resource to supplement and replacing conventional water resource, establishing public outreach network for water demand management and water resource protection, adopting water sensitive urban design to rediscover the added value of water resource to urban development, etc. By reviewing the mechanism of Singapore’s practices on sustainable planning, the existing urban water resources shortage situation in China would be addressed and suggestion for urban water resource sustainable planning and use would also be given.

Abstract:

Increasing population and urbanization pose more and more threats to urban river. Integrated Water Resources Management (IWRM) is possible framework to solve water resource management problems through cross-sectional cooperation, but the vagueness in this concept make its application difficult. This paper focuses on urban river management practices in China and classified the government-guided cross-sectional urban river management projects to a special pattern of IWRM (GIWRM). It is proved to be effective in synthesizing efforts of different government departments, industry and the public and improve the urban river conditions a lot.

Abstract:

Because of rapid economic development and urbanization, water shortage has become a serious problem in the arid region of China. To investigate urban water resource security, the supply demand pressure of water resources and the urban expansion index were analyzed under different developing scenarios in this paper. Based on the economic data of Urumqi, a typical inland city in the arid area, under the present development scenario from 2011 to 2030, a system dynamics model was constructed to simulate the water resource security. The results show that there will be great influence of urban expansion on water resource security in Urumqi in the future. Water resources are projected to become increasingly scarce if the urban expansion is left unchanged in terms of population, economic growth and water-use efficiency. To find a sustainable method for water resource use, four scenarios of urban expansion were set up based on the sensitive variables. Based on comparison of water consumption under the different scenarios, the harmonize scheme for urban water resource security is the best choice for the development of Urumqi. If the impact of urban expansion on urban water resource security alleviates in the future, the main parameters would have to reach a new standard of water use. Reducing the sewage and increasing the reuse proportion of wastewater are also very important for relieving the stress of water shortage. This research can serve as a reference for water resource allocation and urban planning in arid areas.

Abstract:

Due to the rapid development of economy, China has been facing severe water shortage and water pollution problems. This paper discusses three strategies developed for the urban water resource management in China, which is essential for the sustainable development of its economy. These strategies include setting high priority for demand control and water conservation, controlling pollution from the sources and increasing investment for wastewater treatment; and developing untraditional water resources, such as rainwater harvesting, wastewater reclamation, seawater utilization, etc. It is hoped that these strategies may not only solve the water shortage and water pollution problems at low capital and operational costs, but also meet the present and future needs on water resources in China.

Abstract:

Abstract With the quick development of social economy, the sharp contradiction between supply and demand of urban water resources is becoming much more obvious. Comprehensive assessment of urban water resources carrying capacity is of great significance to urban sustainable development planning. In this study, the urban water resources carrying capacity of Qingdao based on basin unit over 2010–2030 is predicted using analytic hierarchy process and system dynamics method. The results showed that the total water demand of all the nine basins have an upward annual trend from 2017 to 2030, among which the domestic water consumption increase obviously. The urban water resource carrying capacity indexes in all basins over 2017–2030 show a downward annual trend under the current social development model. So it is urgent to improve the water resource carrying capacity of each river basin by means of industrial structure optimization and upgrading and active development of new water sources.

Abstract:

Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water–society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social–economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

Abstract:

An evaluation index system of urban water resource vulnerability was constructed to objectively reflect the sustainable development capacity of water resources and provide reference for the construction of sustainable development cities. The improved analytic hierarchy process and entropy weight method were adopted to determine the combined index weights to achieve a unification of subjectivity and objectivity and make the calculation more accurate and reliable. A comprehensive evaluation method was used to build the water resource vulnerability evaluation model. The annual water resource vulnerability index and vulnerability grade were calculated and determined. The results showed that the water resource vulnerability index of Jinan showed a fluctuant trend from 2008 to 2017. The annual vulnerability grade was severe, moderate, or mild vulnerability, and there was a gradual reduction in vulnerability overall, which was consistent with the actual situation. In the future, the water resource vulnerability grade will be reduced if the industrial structure can be further reformed and optimized, and the level of water resource management and the utilization efficiency of water resources can be further improved by strengthening the construction of smart water systems.

Abstract:

Water is the essential element of people's lives, with the rapid growth of population, has become increasingly tense relationship between human and water. In this paper, on the basis of summarizing the existing methods, the application of Chinese traditional harmonious thought, proposes a new model (WUHIS) of assessment of urban human-water relationship, and through the establishment of complete index system to quantify the abstraction of human-water relationship and evaluation. Through three dimensions, the new model from three aspects of the human-water system to conduct a comprehensive evaluation, evaluation of urban river health degree (URHD), evaluation of urban development level (UHDD), and assess human-water coordination degree (HRCD). With relevant data of WUHIS in Xianyang city, Shanxi province, the state of the human-water relationship in Xianyang was assessed from each criterion angle and the result showed that water-urban harmony situation as a whole was on the upswing, but observation of each dimension score respectively, has obvious fluctuation. Through this model, we can clearly know the pros and cons of Xianyang city water resources management, for the Xianyang water resources planning provides a clear direction for the future. This model can be applied in all cities, as long as to modify specific indicators.

Abstract:

China is a country where the levels of water resources per capita are extremely low. With the rapid development of urbanization, water resource shortages have become a bottleneck existing in more and more cities. This study considers the comprehensive management of urban flood control, water supply, water and the ecological environment, catches the main contradiction between “water deficient” and “water rich” in cities, puts forward a comprehensive utilization pattern for urban water resources by emphasizing the utilization of rain–flood resources. After a simulation study, a better regulation pattern is brought out and achieve multiple benefits based on the river system of Gucheng Lake, which is located in Nanjing, Gaochun district, by optimizing conventional regulation. The results show that two parameters, the low water level (LWL) below which Gucheng Lake stops supplying ecological water, and the high water level (HWL) where Gucheng Lake stops importing water from rivers, are the key parameters to decide the regulation benefits, and the LWL of 9 m and HWL of 12 m is the best combination in river network regulation, the annual potential utilizable of rain–flood resources of Gucheng Lake river system can reach 57 million m3 per year, through the comprehensive utilization of the rain–flood resources, the negative effect of flood is effectively reduced and the disaster is controlled on one hand; and the water demand of urban and rural water supply, 100,000 m3/day, is effectively guaranteed as well as the regional ecological environment is improved on the other hand.

Abstract:

The rapid and haphazard urbanization in Kathmandu and expansion of built-up area to the peri-pherial rural landscapes has resulted to formation of peri- urban areas which are now themselves transforming into urban form. Simultaneously, the water being diverted or transferred from these peri-urban areas is rapidly evolving. This paper describes the changing modes of urban oriented water flow from the peri-urban landscape of Kathmandu and the implications of this water transfer on water security of peri-urban areas. Through series of semi-structured interviews, formal and informal discussions with local people and key informant interviews, the study found that Matatirtha, a peri-urban village, has traditionally been a source of water for the domestic water demand in Kathmandu. However, the social and economic developments have induced a paradigm shift in urban water transfer from the area and promoted the economic benefits as a way of compensating the loss of local water resources. Moreover, the increasing opportunities of economic benefits through water in absence of regulatory mechanism have facilitated exploitation of resources. This, therefore, created need of strong mechanism, promoting insights for sustainable management of water resources and contribute to improve rural urban linkages through optimal use of water resources.DOI: http://dx.doi.org/10.3126/njst.v15i1.12025 Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 99-106

Abstract:

The common perception of people about recycling involves reusage of aluminum cans, glass bottles, and newspapers, whereas recycling of water resources is a most important aspect nowadays. Water recycling is known to reuse cleaned wastewater for beneficial applications including agricultural and landscape irrigation, industrial activities, and replenishing a groundwater using the latest technologies. The current methods have some flaws in the evaluations of water resources’ recycling systems such as large mean square error, time complexity, and low-evaluation efficiency; therefore, this paper proposes an online evaluation method for the recycling process of water resources in urban landscaping. The health model of water resources recycling in urban landscaping has been analyzed using fuzzy-based approach. Second, the evaluation index system of water resources’ recycling is also analyzed using the ecological water-level analysis results, water resource quality, water resource abundance, and water resource utilization rate. Then, the extension of analytic hierarchy process (AHP) is utilized to calculate the weight of water recycling evaluation index. Then a fuzzy-based comprehensive evaluation method is used to find the online evaluation model of the water recycling. Eventually, the evaluation of the effect of water recycling in urban landscaping is performed and analysis is made for decision-making. The results prove that the proposed AHP and fuzzy method has a low mean square error and high accuracy.

Abstract:

The security of water resources is the core content and ultimate goal of urban water resource management agencies. The management of water resources is directly related to the needs of urban residents’ lives and the area’s socio-economic development. How to determine the effective evaluation indicators and methods is an important prerequisite to solving the water resource security problem. This study took Luoyang City as the research area and constructed a water resource security evaluation index system based on pressure-state-response framework. An analytic hierarchy process and entropy weight method were used to determine the index weight. A set pair analysis model was then introduced to evaluate the security of water resources in Luoyang from 2006 to 2016. The results of this study show that the standard of water resource security generally improved in Luoyang in the latter years of the study period. From 2006 to 2008, Luoyang was graded at the Insecurity Level. This compares to a slightly improved grading of Critical Security Level from 2009 to 2016 (except for 2013). However, the overall grade is still low. The pressure on the Luoyang water resource system mainly comes from the development of the urban socio-economy, which in turn has caused problems for both the quantity and quality of water resources. Therefore, a series of countermeasures have been introduced as a means of improving the water resource security of Luoyang, and these measures have achieved certain results. However, further improvements to the efficiency of water resource utilization and strengthening the management and protection of water resources remain necessary.

Abstract:

We surveyed and selectively sampled the major water sources in Bamyan city and the surrounding area to assess the water quality. Water quality measurements were taken in situ and more samples were collected for laboratory analysis from canals, rivers, springs, wells, and water supply systems. In urban areas, water supply systems provide 36% of the drinking water, but in rural areas, this source accounts for only 7% of drinking water supplies. Wells comprise 33% and 15% of urban and rural water supplies, respectively, while canals and rivers are modest water sources for Bamyan communities. Basic water quality parameters, such as pH, EC, and TDS, were variable with high values in some areas. Most of the samples fall in the range of potable water, but some had a high TDS and EC indicating that there is the potential of contamination. Values of pH were mostly were mostly in the range of drinking water (6.5–9.5). A Drinking Water Quality Index (DWQI) was calculated to better understand the water quality issues for the potable water supplies. Subsets of representative samples were analyzed for 17 selected chemical elements and other constituents. Barium (Ba) was detected in almost all of the water samples, while arsenic (As) was detected in about 9% of the analyzed samples, and this was mostly associated with thermal springs. Concentrations of Mn and Cu in some samples exceeded that of the water quality standards, while Zn concentrations were below tolerable limits in all of the samples. Most of the analyzed water samples were hard, and several samples showed evidence of microbial pollution in urban areas. Rivers originating from snow and glacier melting had excellent quality for drinking.

Abstract:

Water and land resources are important material bases of economic and social development, and their spatial patterns determine the pattern of the urban development. The development and expansion of coal-resource-based cities have introduced new societal problems, such as the overlapping of new city construction areas and underground coal resources. Underground coal mining also leads to surface subsidence, which destroys water and land resources and seriously affects the sustainable development of coal-resource-based cities. The surface subsidence area takes a long time to stabilize, and may form a large waterlogging area due to the high groundwater level, thereby increasing the difficulty of reconstructing mining subsidence areas. In this context, a scientific and complete method for reconstructing the spatial pattern of water and land resources in unstable coal mining subsidence areas within urban is proposed in this paper. This method initially predicts the surface subsidence value and then divides the subsidence area within the urban region into the waterlogging area and the non-waterlogging area according to the surface subsidence value. The waterlogging area will be renovated into a landscape lake district in the city by a series of transformation measures. Afterwards, goaf rock mass activation and surface stability evaluation analyses are performed in the non-waterlogging area. According to the evaluation results, land resources can be divided into unaffected, restricted and prohibited building areas, with each area being transformed differently. The Lv Jin Lake in Huaibei is selected as a case study, and the proposed method is applied to reconstruct its water and land resources. The original spatial pattern of the large-scale waterlogging area and abandoned land due to mining subsidence in urban areas is then reconstructed into a spatial pattern that integrates the urban landscape, scenario living and eco-tourism. Compared with traditional subsidence area management, the proposed method greatly increases the utilization value of water and land resources, improves the urban ecological environment, enhances the urban quality and effectively alleviates the problems of land shortage and human–land conflict in coal-resource-based cities.

Abstract:

In urban planning, urban population and development is restricted by water resources, so we should pay attention. Taking Changchun-Jilin region of Jilin Province for example, water resources carrying capacity per capita is adopted to control the capacity of the urban population. On this basis, it considers the economy, water resources, the state of the urban population scale and transferring water to do parallel computing. Then the controlling index of urban population capacity is mainly obtained through the optimal solution. This paper made water resources as quantitative indicators to control the urban population, in order to solve the relationship of urban-water-ecology

Abstract:

Water resources are a major factor in the spatial layout of agricultural production and urban construction, which is an important part of China’s ongoing territorial spatial planning. In order to assess the constraining and guiding effects of water resources on territorial spatial planning, water resources suitability evaluation needs to be carried out at the grid scale. Traditional basin or regional-scale indicators of water resources cannot satisfy the requirements with high spatial accuracy in territorial spatial planning, because the internal differences could not be described. In this study, irrigation water supply cost index (CIA) and urban water supply cost index (CIU) were evaluated to characterize the affordability of potential water supply costs by simulating of optimal water supply path. Further, grid-scale indexes of water resource suitability for agricultural production (WRSA) and for urban construction (WRSU) were constructed. The grades of WRSA and WRSU were classified at a 20 m grid scale in Baiyin City. The areas of water resources that were suitable, relatively suitable, less suitable, and unsuitable for agricultural production were 381.0 km2, 3354.7 km2, 3663.9 km2, and 12,700.7 km2, respectively, accounting for 1.9%, 16.7%, 18.2%, and 63.2% of the total area of Baiyin City. The areas of water resources that were suitable, relatively suitable, less suitable, and unsuitable for urban construction were 1657.7 km2, 4184.5 km2, 1177.7 km2, and 13,075.7 km2, respectively, accounting for 8.2%, 20.8%, 5.9%, and 65.1% of the total area of Baiyin City. Coupling analysis with land use and land resources suitability were carried out in this study, which showed that the grid-scale WRSA and WRSU could well characterize the spatial differences of water resources suitability for agricultural production and urban construction. The results of the Geodetector-based study show that the WRSA and WRSU indicators have better explanatory power for the land-use spatial distribution compared to indicators such as water distance. Therefore, the indexes could provide scientific support to delimit agricultural space and urban space, and are effective means of “determining regional functions by water resources“ in territorial spatial planning. Furthermore, the indexes could be applied to other arid and semi-arid areas, and also hilly areas, where water supply suitability plays a restrictive role in agricultural production and urban construction.

Abstract:

<abstract> <p>Effective water resources management and water availability are under threat from multiple sources, including population growth, continuing urbanisation, and climate change. In this context, current water resources management requires a conceptual rethink, which is lacking in the urban water resources management literature. This paper addresses this gap by rethinking urban water resources management from a water-centric perspective. The paper discusses a conceptual rethinking of water resources management towards a water-centric water resources management system underpinned through combining nature-based solutions (NBS), green infrastructure, and water soft path approaches. It is concluded that through adopting a blend of NBS, green infrastructure, and water soft paths, a water-centric water resources management approach focused on achieving sustainable water availability can be developed. It is further concluded that in transitioning to a water-centric focused water resources management approach, water needs to be acknowledged as a key stakeholder in relation to guiding a transition to an effective holistic catchment-wide water-centric water resources management system focused on achieving sustainable water availability.</p> </abstract>

Abstract:

Wastewater reclamation and reuse are becoming important components of the management of urban, regional and national water resources. Recently, not only countries with chronic water shortage, but also urban areas in temperate climates have considered and implemented wastewater reuse schemes expanding the scope of consumptive uses to include toilet flushing and landscape irrigation, using dual distribution systems and even the reuse as potable waters is being considered and evaluated. Israel is an example of intensive reuse in agricultural irrigation and much experience has been gained in treatment, seasonal reservoirs and establishing quality requirements. The economical justification of wastewater reuse schemes should take into account the overall treatment costs, the ‘environmental and health allowances', i.e. the cost of treatment required even when reuse is not practiced, the benefits of water and the savings in conveyance and pumping. The paper also briefly describes the two largest wastewater reclamation projects in Israel, namely: the Kishon Complex Scheme and the Dan Region Scheme, both aimed at unrestricted agricultural irrigation of all crops.

Abstract:

Rising urban populations, limited natural resources (following the German Federal Environmental Agency, natural resources are resources that are part of nature. They include renewable and non-renewable primary raw materials, physical spaces (surface areas), environmental media (water, soil, air), flowing resources (e.g., geothermal, wind, tidal and solar energy) and biodiversity. It is irrelevant here whether the resources serve as sources for producing products or as sinks for absorbing emissions (water, soil, air)) and climate change require a new approach to urban planning. Recently, international, European and national programmes, concepts and framework documents have been created to promote the implementation of measures for more sustainability, resource efficiency and climate resilience in urban districts. In the funding measure of the German Federal Ministry of Education and Research’s “Resource-Efficient Urban Districts for the Future-RES:Z”, twelve funded research project networks are dedicated to understanding the impacts that urban districts have on the resources of land, water and material flows, as well as the resulting impacts on urban green spaces and energy issues. By considering the different resources involved, it is shown that the optimisation of their use cannot take place independently of each other. This may even lead to conflicting goals. Use conflicts can be recognised at an early stage and measures can be tailored to the specific neighbourhood context when applying an integrated approach that provides a common view on all of the aforementioned resources. Special attention is paid to solutions which create numerous benefits i.e., multifunctionality. The RES:Z funding measure utilises living labs for the research on and implementation of solutions. This lays the foundation for a sustainable transformation of urban districts and the basis for further research.

Abstract:

Abstract The present paper describes a proposal of multiple reuse of wastewater for the town of Camigliatello Silano, in the province of Cosenza, Italy. Camigliatello Silano is a locality devoted to agriculture and to both winter and summer tourism. There are several issues related to the management of water resources of the locality, including the lack of regularization of the discharge of urban wastewater with Italian and European regulations, poor availability of the resource for the irrigation sector, and necessary improvements in winter tourism. To solve these problems, this paper proposes a possible solution for the management of the water resources of the locality, through the reuse of wastewater. The proposed solution provides the reuse for agricultural purposes during the irrigation period and an innovative reuse for the production of artificial snow in the winter season. The reuse for irrigation allows the increase of water resources in agriculture, while the reuse for the production of artificial snow allows a longer skiing period. The proposed solution also solves the problem of regularization of wastewater discharge with positive effects on the environment and water resources.

Abstract:

Whereas the world population is increasing at a high rate, especially in urban areas, water resources have not only remained constant, but are being polluted at a high rate, which inevitably results in fresh water scarcity. Current urban water management concepts and practices cannot adequately respond to these changes. There is need for water professionals to change the way they manage water resources in urban areas if we are to ensure economic and environmental sustainability. In addition to consideration of supply-side options, we need to apply water demand management (WDM) tools both on the utility and end-user sides. This paper describes the basic concepts of WDM, provides a case study of their application in Bahrain, and briefly introduces the five-year EU-funded SWTCH Project that aims at creating a paradigm shift in urban water management practices.

With the quick development of economy, increase o f population and urbanization, urban water security becomes a limited factor to fulfill the urban sustainable development. Qinhuangdao is a water shortage of resources and pollution-induced water shortage city. Under the major background of global warming, the climate of Qinhuangdao becoming warmer and drier in recent years, the precipitation has decreased correspondingly. The rivers runoff reduces obviously and the level of the groundwater drops. The quantity of usable water resource is reduced significantly. Impacted by the urbanization, social-economic development and rapid population growth, the demand of water resource increases continuously. The security situation of water resource in Qinhuangdao is becoming more severe. Through analyzing the water resource situation, existing issues and reasons in Qinhuangdao city, the author proposed regulating approaches to ensure safety of water resources.

Abstract:

The main challenge in the twenty-first century is to work towards a more resilient urban world and sustainable. In the context of a global urban strategy, endurance is the attention to the capacity of urban systems, including the natural environment, the built environment, social and economic elements; to be able to manage change, to learn from a difficult situation and be in a position to rise from urban problems. Globally, the townsfolk face a water crisis within the next ten years, as the impact of climate change in exhaust emissions will affect the quality of air, land and water; which will ultimately reduce the quality of the environment. Sustainability questioned whether certain aspects of the day-to-day activities, and the systems of community life, can be ongoing into the futureonce again from the standpoint of social, economic and environmental. Eco city is a phrase that is often used in ecological issues raised in the concept of sustainable urban planning and green city embodiment of the challenges ahead in sustainable economic development, and the future development of smart green city. The convergence of technology and environmental issues has changed the world economy that offers a green city promising future - a city that appreciates natural heritage and offer all parties involved. This paper will discuss green infrastructure as water management control system in urban development concepts that contribute to build a sustainable green city management.Key words : green infrastructure, water management system.

Abstract:

Under new democratic regimes in the countries of the Global South, governance innovation is often found at the regional level. This article, using the concept of institutional capacity, shows that powerful efforts affecting regional water resource coordination emerge locally. The article analyses fresh water cooperation in the urban region of Cirebon, Indonesia. It is shown that the city and its surrounding regions in decentralising Indonesia show signs of increasing institutional capacity between local actors. An informal approach and discretionary local decision-making, influenced by the logic of appropriateness and tolerance, are influential. At the same time, these capacities are compromised by significant inequality and a unilateral control of water resources, and they are being challenged by a strong authoritarian political culture inherited from a history of centralised government. The article points to the need to establish greater opportunities for water governance at the regional level to transcend inter-local rivalry, and thus improve decentralised institutional capacity further.

Abstract:

India is rich in natural water resources, but because of the uneven distribution of resources and improper management, the major part of the country suffers from drought almost every year. The present study is based upon the inappropriate management of water resources in the urban and rural area of Jabalpur. The present paper intends to find out the actual condition of management of water resources by the municipal corporation of Jabalpur, whether the citizens of Jabalpur are benefitted through the policies made by the government for the equal distribution of water resources, are the policies adequately implemented and monitored once they are made?The data has been collected from secondary and primary sources, and simple percentage method has been used to analyze the collected data. The outcome of the study reveals that the government is trying to manage the water resource and is concentrated on the equal distribution of water in both urban and rural areas. Many policies have been prepared by the local government, but ineffective monitoring is the leading cause of improper management of water resources.
