AbstractWater resource management is a major concern in Marquenterre, a maritime plain located in the western part of the department of Somme. Water management is particularly indispensable for protecting wetlands in Marquenterre, regulating water usage, and avoiding saline intrusion into aquifers.Various approaches including geologic modeling and hydrogeological and hydrogeochemical studies were used to prepare a conceptual model of the Marquenterre hydrosystem and to provide better water management in this sector.The conceptual model shows that the chalk aquifer and the various Quaternary deposits aquifers are in hydrogeologic continuity. No seawater intrusion has been discovered in groundwater. Salinization discovered at depth is a result of the most recent marine transgressions. Finally, wetlands are primarily supplied by the chalk groundwater or by rainfall.The study results are used to direct policies of surface and subsurface water resource management. The proposed conceptual model may be useful for other coastal aquifers in the English Channel to address challenges of managing the chalk groundwater and backshore swamps.

Sustainable utilization of peatland is required for balancing production and conservation efforts. On peatland, one of the main components to examine sustainability is understanding the carbon balance. This research was conducted in Pulau Burung, Riau, Indonesia, which has a long history of peatland utilization for agriculture. The sets of utilized data included historical data of water management on peatland represented by water table and subsidence rate, next to carbon density of peat soil. The results showed the function of integrated water resource management made the yearly average water table depth is 48 and 49 cm in 2018 and 2019, respectively. The range water table is between 31cm to 72 cm due to season variability and crop requirement. Consequently, the rate of annual subsidence is averaging at 1.7 cm with cumulative subsidence in 32 yr is 54.1 cm. Since the water never drained since the establishment, the subsidence rate of the first five years is averaging only at 3.3 cm yr–1. Low subsidence rates minimize annual carbon loss during the peatland utilization around (30 to 200) Mg CO2 ha–1 yr–1. In 32 yr, the water management in peatland utilization in Pulau Burung has prevented 2 000 Mg CO2 ha–1 to 4 925 Mg CO2 ha–1 loss compared to other cultivated areas in peatland. Further, this paper discusses the practice that resulted in low emission of coconut agriculture in Pulau Burung as one of sustainability dimensions, which support the other sustainability aspects, that is the thriving local livelihood.

The goal of this paper is to identify the major outlines of innovative, integrated and decentralized water management practices, training, research, and development needs in various aspects of soft path water resource management in developing countries of Asia. The decentralized water strategies including science, regulations, training, government policies, and funding for some of the developing countries in Asian region are reviewed. There are two primary ways or paths of meeting water-related needs; one the “hard” path, and the other “soft” path that complements mainly decentralized and open decision-making, application of efficient technology, and environmental protection. One of the soft path decentralized solution being implemented in many developing countries of Asia is small scale rainwater harvesting and management and both government and non-government sectors are promoting the practice on a regional community and family basis. Overall, the paper aims to contribute to the ongoing development of environmentally sound and economically viable approaches to water management in the developing world.

Daunting Task

Abstract Dhaka the capital of Bangladesh is facing a serious water scarcity problem due to the big gap between demand and supply of water system. When accelerating water scarcities and pollution in and around urban centers are superimposed on issues like continuing urbanization, lack of investment funds for constructing and maintaining water infrastructures, high public debts, inefficient resources allocation processes, inadequate management capacities, poor governance, inappropriate institutional frameworks and inadequate legal and regulatory regimes, water management in the megacities poses a daunting task in the future. To overcome these water related problems, water can be a designing element for structuring future development with the combination of sustainable approaches for social and physical transformation, open up opportunities for water management system. Therefore an integrated approach like integrated water resource management (IWRM) system is required that responds to problems that are all interrelated. Alternate supply and demand management tools such as ground water recharge, rainwater harvesting, effective water pricing, reclaimed water use are suggested to meet the deficit of current supply system through the efficient use of the scarce resources available. Institutional reform and improved water planning are required to facilitate economic growth and social development. Finally, human resource development is identified as key factor for the sustainable effective management of this valuable resource.

Abstract Water management is assuming more and more importance as freshwater resources are becoming scarce, both in quality and in quantity, across many developed and developing countries. This trend can be attributed to population growth, industrialization, growing agricultural demand, poor water management practices and climate change. In attempting to deal with the intensification of water quality- and quantity-related problems in recent decades, many countries have revised their water resource management policies and legislation, introducing new institutional frameworks and management instruments. Considering regional geographic and cultural distinctions, the present article aims at comparing the models of water resource management in the European Union (EU) and in Brazil. Institutional and legal arrangements currently in place, water planning and management instruments currently in use, assessments of water body status and watershed diagnoses were analysed. Main strengths and weaknesses of each water management system are pointed out in the conclusion. Main challenges for the water sector, and highlights of the converging and diverging points concerning water resource management systems, in each region, are discussed.

Aims: This study sought to evaluate the adoption of water resource management strategies in hotels in an attempt to attain water sustainability. Specifically, the research sought to assess the current structural and non-structural water resource management strategies adopted by selected hotels in the environs of Lake Naivasha; establish the perceived effectiveness of both the structural and non-structural water resource management strategies adopted to enhance water sustainability; and compare the structural and non-structural water management strategies in terms of their effectiveness in promoting water sustainability in hotels within environs of Lake Naivasha. Study Design: The study adopted a case study design. Place and Duration of Study: This study was conducted in hotels within the environs of Lake Naivasha between May and December 2010. Methodology: A census of 30 Class (A) registered hotels was conducted, and purposive sampling was used to select 120 respondents from the management staff within the selected hotels. Convenience sampling was used to select 8 managers of water management bodies who acted as key informants during personal interviews. Primary data was collected from the hotel management staff using questionnaires and from managers of water management through personal interviews. Data from questionnaires were analysed using the Statistical Package for Social Science (SPSS) to derive descriptive statistics on the implementation of WRM strategies. Results: Findings revealed that a majority of the sampled hotels had embraced water resource management strategies through the development of alternative water resources, use of water saving technology, treatment of recycled water and use of water saving manuals. Further, the structural water resource management strategies were perceived to be more effective as they impacted more on reducing the operating costs, promoted environmental conservation and were more preferred than the non- structural strategies despite being more expensive to implement.  Conclusion: It is concluded that water sustainability is however achievable through a combination of a variety of WRM strategies.

This chapter summarizes the collective work of a team of students who participated in the 2004 International Space University Summer Session Program in Adelaide, Australia. The project is called STREAM, which stands for Space Technologies for the Research of Effective wAter Management. The work represented in this chapter was accomplished as part of the intensive space studies curriculum offered during the summer session. The team project focused on the importance of fresh water resource management and its impact on the surrounding communities. The team explored various space technologies and their current and future potential to enhance water resource management. A real world case study of Australia’s Murray-Darling Basin (MDB) was performed to provide the central focus of the project. Based on the results of the case study, the team then extrapolated their results to other regions of the globe that are experiencing challenges to their fresh water supply. A significant space technology recommendation developed by the STREAM project team was to improve the soil moisture measurement capabilities in the MDB. The primary goal of the STREAM project team is that the recommendations outlined in the extensive final report (STREAM Team, 2004) will receive full attention from policy makers concerned with the water issues surrounding the MDB.

The World

The world faces an unprecedented crisis in water resources management, with profound implications for global food security, protection of human health, and maintenance of all ecosystems on Earth. Large uncertainties still plague quantitative assessments of climate change impacts and water resource management, but what is known for certain is that the climate is changing and that it will have an effect on water resources. Therefore, increased efforts will be needed to plan and manage water supplies in the future through increased monitoring and understanding of the interrelationships between population size, climate change, and water availability. The focus of water management is gradually shifting from developing new water sources to using existing water sources more effectively and efficiently. The world needs policy change in water management. Respect for water resources and their value is the starting point of deliberations. Governments have the essential water management function: to protect and allocate water resources to allow both individual and collective interests to benefit from water. Societies must also lead in understanding, provisioning for mitigating the impact of disasters, ranging from extreme droughts to unprecedented floods, caused by climate change and poor management of water and land. Public funds will likely remain the main source of water sectoral funding. It is up to governments to invest wisely to enhance the crucial role that water has for social and economic development in a country. Integrated water resource management strategy is accepted as a global model for achieving the objective of a sustainable water management system.

Meta Regression Analysis

Water management can improve the quality of valuable ecosystem services but can be costly to implement and the management costs are covered by national taxes collected by water users. Based on 30 valuation studies of water quality improvement from the Environmental Valuation Information System (EVIS) database provided by Korea Environment Institute (KEI), a meta-regression analysis was employed to measure the benefits that major river basins provided to the society. We compare these benefits to the costs, namely River Management Funds (RMFs) which are financial resources to support a variety of projects for managing and improving upstream water quality. Based on benefit-cost comparison, this study evaluates the efficiency of water resource management in South Korea. This study also provides policy options that are helpful to maintain the sustainability of water resource by improving the planning and performance of water management in the long run.
