The purpose of this paper is to focus on the assessment of water resources in the Seybouse middle sub-basin. Analyses of water and various current uses are used to draw attention to the necessity of implementing water resources integrated management into a plan aiming at a rational exploitation.

Any sustainable management of water resources is closely dependent on the ability to accurately assess the quantity and quality of available water resources that are used as water supply for the population, agricultural production, industrial or energy. The analyzed and processed available data serve as database for integrated water resources management.

Analysis shows that the annual water supply is represented by 71 percent of the surface water resources and 29 percent of groundwater. The total volume of water used in the middle Seybouse basin is estimated at 36.22 hm3/yr. The predicted water needs are estimated to 79.19 hm3/yr in 2030. The groundwater of the Guelma alluvial aquifer exhibits a calcium chloride-facies general trend. The evolution of the chemical elements is related mainly to the geological nature of the reservoir lithologies. The heavy metals do not exhibit clear anomalies, but the surface water of the majority of streams is heavily infected with bacterial germs.

The obtained results show that the Seybouse middle sub-basin needs twice as much water by 2030 for the different uses. This requires a better management of water resources for a sustainable development in this specific region of Eastern Algeria.

This paper is devoted to the management of water resources in a specific region (the middle Seybouse basin) which constitutes an interesting example of considerations to be taken for a sustainable development.

The purpose of this paper is to spur further exploration of blockchain technologies for environmental peacebuilding, specifically through water management. Although the environmental peacebuilding field acknowledges the potentially transformative nature of frontier technologies, most existing studies do not address how such technologies can contribute to peacebuilding through improved natural resource governance. Using a theory synthesis research design, this conceptual paper connects these studies to discuss how blockchain technologies in water management may contribute to environmental peacebuilding through the efficient and transparent management of natural resources.

The authors use a conceptual approach and a theory synthesis research design to present potential mechanisms through which blockchain technology can potentially contribute to environmental peacebuilding.

The authors discuss the limitations in the literature on environmental peacebuilding, blockchain and water management, concluding that the third generation of studies should focus on the role of frontier technologies. This approach should especially address the negative consequences of technology for peacebuilding objectives. The authors argue that blockchain applications in water management can potentially contribute to environmental peacebuilding objectives in three ways: (i) creating a mechanism for confidence-building in low-trust contexts through automated and transparent water transactions, (ii) facilitating postconflict economic development through attracting capital and increasing the efficiency of water management and (iii) improving governance through greater transparency and local participation in natural resource management.

To the best of the authors’ knowledge, this study is among the first to conceptually explore the use of blockchain technology for water management in the context of environmental peacebuilding. The insights from this study can guide policymakers of conflict sides that focus on resolving issues such as lack of governance and low state agency.

Economic development requires the use of natural resources. Increasing population makes increasing demand on such resources thereby leading to the degradation of the environment. Excessive use of resources can lead to a situation where declining supply can no longer satisfy the demand. Hence, without conservation and prudent management of resources the environment cannot be preserved. This paper examines the case of water supply, which is the fundamental requirement for the sustenance of all life forms on earth. The human population is expected to double to at least 8 billion in the next 30 years and the worldwide demand for water is estimated to increase by a staggering 650 percent. However, the total supply of fresh water in the world is limited as 99 percent of the earth’s water is either saline or frozen. Of the remaining 1 percent most is ground water and soil moisture. The net availability of fresh water for human consumption is one‐hundredth of 1 percent. And not even all of that can be used. Hence, how can the continued availability of fresh water resources to satisfy the growing need of the rising population be satisfied? Conservation of fresh water can be achieved to some extent by reducing the demand by imposing a price/or raising the prevailing price on the use of water. However, while conservation can stretch the supply by reducing demand, for ensuring the long‐run adequacy of supply, it is necessary to apply a prudent environmental management policy which will prevent the destruction of forests and natural resources and apply a policy of active regeneration of forests. While the supplies of water make the forests survive and grow, preservation of forests allows water resources to survive. Forests cannot be preserved unless the destruction of hundreds and thousands of wetlands to make way for human settlement and industrial development is prevented and property rights of landless people are recognised. Thus for a prudent and efficient management of water resources to be effective, the state must adopt the ecologically sustainable approach to development. This paper examines these issues.

The objective of this article is to propose a panel of management performance evaluation indicators at operator level. This panel would be the tool to be made available to an observatory that should be set up by regulation. The proposal comes at the right time given that Morocco is planning a major reform of the sector very soon. A framework law has already been promulgated for this purpose (Law 51-21 relating to the reform of public establishments).

The proposed panel is the result of (1) a review of the literature dealing with public management theories, in particular those relating to industrial and commercial public services and whose character is captive. The management of the latter requires a great deal of caution to preserve their economic balance and consequently their sustainability. (2) A review of experiences of countries is chosen because of contextual their similarities with Morocco like France having a similar legal background, Tunisia and Algeria chosen for geographical and economic similarities. The British experience is also discussed for what it represents as a liberal model in the management of public water and sanitation services, as opposed to the German model also studied and which stands as the only country where the management of public services has almost always been a communal prerogative. The analysis of these models has made it possible to identify management evaluation practices that could be adapted to the Moroccan context. (3) Research work by practitioners and reports from specialized international institutions (International Water Association [IWA]). (4) A critical analysis of a multitude of management and activity reports from 12 autonomous authorities and 4 private delegates covering 16 million inhabitants of the urban environment. A total of 15 indicators are developed. They aim to assess the effectiveness of management in terms of saving drinking water and preserving the natural environment from the pollution of water resources.

Approximately, 15 indicators for assessing water resource management in public water and sanitation services are proposed. These indicators relate to the efficiency of pipe networks, the performance of storage systems and losses in users' homes. Indicators specific to liquid sanitation systems, particularly with regard to the control of wastewater overflows into the public highway and their treatment before discharge into the natural environment, are also proposed.

The application of the results of this research could be confronted with its appropriation by the operators. Indeed, the investment involved in setting up the proposed evaluation system, as well as the conflict of interest that may arise in the process of formalizing and standardizing the system at the national level, may slow down the process of setting it up.

In practice, the implementation of a system for evaluating the performance of water resource management in public drinking water and liquid sanitation services would make it possible to optimize the volume of water to be mobilized. Substantial savings are expected both at the level of the resource itself and at the level of the investments that accompany the realization of the mobilization and distribution infrastructures. These savings will be very useful for the creation of other similar services and to serve more people.

The distribution of drinking water and liquid sanitation is a vital human need. These services are extremely captive. They are key factors in the socioeconomic development of the territory and the citizen. The impact is transversal and affects the lifestyle of the populations. On the one hand, it favors the sedentarization of the populations and on the other hand, preserves their health by fighting against the diseases of water origin. In addition, the comfort that it provides in the daily life of users is highly coveted when they are delivered in a modern way and arranged with modern technologies.

The regulation of public drinking water and liquid sanitation services in Morocco is the weakest link in the sector. The Ministry of the Interior is legally responsible for setting up a standard system for evaluating the management of these services to fill this gap (organic law 113-14 on municipalities). Unfortunately, this initiative is not yet underway. The opportunity to apply the results of this research is well timed. Morocco plans to launch a global reform of the sector starting in 2022–2023 (Law 50-21 on the reform of public institutions).

The study aims to explore institutional adaptation for sustainable water resources management at the local level in the context of increasing climate-related challenges in Zimbabwe using the case of a semi-arid area in the mid-Zambezi Valley, north of the country.

Inspired by the critical institutionalism approach, the study uses qualitative methods (i.e. key informant interviews, semi-structured interviews, community workshops and documentary review) to understand the role of different formal and informal water-related institutions vis-à-vis responding to climate-related challenges in the case study area, and how the identified institutions can improve their efforts in the context of national water and environmental policy and regulation frameworks. Thematic analysis was used for data analysis.

The study found that climatic challenges in the case study area, as in most of rural Africa, have raised the stakes in local water management with respect to regulating access to and balancing competing interests in, and demands for, water. It ultimately argues for the embracing of complexity thinking and flexibility in local water management as well as clear coordination of institutions across scales in the face of increasing climate-related challenges.

The study adds to case studies and evidence-based analyses focused on institutional alternatives for climate adaptation vis-à-vis water resources management in water-stressed rural African communities.

The purpose of this paper is to assess the issues faced by managers of inland waterways in the Southeastern USA as a guide for improvements to spill management information systems.

A survey was administered to a group of over 300 professionals representing multiple organizations involved in water quality management and/or spill response in the Southeast region of the USA to query their perceptions on leading demands and issues faced in management of inland waterways both on a daily basis and during spill response efforts.

Survey results indicated that communication is often the “weak link” in both water management and spill response activities, and that enhanced spill management information tools could serve as a valuable resource in addressing this problem. Display of spatial/visual information was deemed to be especially important to spill response personnel and should be included in the next generation of spill response systems.

The scope is limited to the Southeastern USA, but similar results would be expected in other regions where management of surface water is of concern.

In these trying economic times, the survey results serve to rank order decision‐support priorities to which available resources should be allocated and indicate areas of interest for improved support in both water resource management and spill response.

The paper provides the first documentation of the demands and decision‐support priorities of inland waterway resource managers and spill response personnel.

The aim of this chapter is to determine the need for water management and accounting.

This chapter first gives an overview of water-related business risks and exposes the need for sound corporate water management and accounting; it then critically examines water-related issues from an accountability perspective. Furthermore, it gives an overview of Australian Standardised Water Accounting (SWA) and General Purpose Water Accounting (GPWA) as possible practices to strengthen water disclosure.

The present study confirms the need for, and the importance of, transparent, high-quality, credible and comparable water disclosure. Water is considered a public good and involves a public interest and, consequently, public responsibility for its usage, management and protection. Following this line of reasoning, the chapter draws attention to the need for accountability to be ‘public’ or at least shared between crucial stakeholders (government – at national and international levels, water industries, communities, environmentalists, NGOs, etc.).

Company efforts are commonly focused on internal and self-referred operations. The different and conflicting uses that may be made of water, and the fact that water is geographically and temporally sensitive, necessitate a search for more flexible and more extended forms of accountability. An implication of these findings is the need and opportunity to switch focus from a single/private perspective to a more general/public one, with benefits for all the stakeholders.

This research enhances our understanding of water management and accounting and may serve as a sound base for future studies on this challenging topic.

The aim of this research is to analyse the literature on drinking water management in Mexico City and Singapore, considering water supply, institutional organisation and management, and rates so as to propose recommendations for improvement in the water management of the Mexico City.

The preferred reporting items for systematic reviews and meta-analysis (PRISMA) methodology is used to review the literature on drinking water management in Mexico City and Singapore in time periods from 1325 to 2021 and from 1819 to 2021, respectively, emphasising the contemporary part. The information search was realised through different prestigious databases and official documents from the governments of Mexico and Singapore, as well as international organisations. After analysing, 40 documents were included to discuss the results.

There is a contrast between water management in Singapore and Mexico City because Singapore has strong institutions coordinated with each other along with the private and social sectors and has efficient fundraising and infrastructure investment systems. Although they are cities that developed in different circumstances, a comparison between them allowed to glimpse some aspects that may be useful to replicate in Mexico City.

This research is novel because there is no comparative analysis like the one presented in the literature, so it is suggested to continue delving into the topics covered in future research to have more elements that allow improving drinking water management in Mexico City.

This paper aims to develop a framework to examine corporate water reporting (CWR) that considers the context in emerging economies and determine if and how companies are addressing the distinct water-related challenges and opportunities that they face in any given location.

This study combines a concise profile of the context of water resources management in Peru with a review of CWR guidelines and thematic content analysis of water information in sustainability reports for 34 companies operating in Peru. These data are then used to inform the development of a CWR typology via the use of a cluster analysis complemented by within-case and cross-case qualitative analysis of companies.

This study highlights the incomplete nature of most CWR practices of companies in Peru, with an emphasis on internal firm operations. Where companies do provide information on water risk and stakeholder engagement, there is insufficient detail to provide a clear picture of contributions to sustainable water management at the local level. The main drivers for CWR in Peru appear to be pressure from international markets, regulation and other normative issues.

The findings indicate that companies need to place more emphasis on the local context when reporting on water risks and activities, which could be achieved through the use of CWR frameworks that integrate both international and sectoral CWR guidelines, along with indicators related to good water governance, water, sanitation and hygiene service delivery and the sustainable development goals, as together they provide a more comprehensive reflection of the broader challenges and opportunities related to corporate water management.

This paper presents the first framework specifically developed to evaluate CWR practices with consideration of the context of an emerging economy.

The purpose of this paper is to assess the long‐term ability of the Integrated Southern Ghor Project (ISGP) to meet the required water demands, assess the resulting energy requirements, pumping costs, water transfers, benefits of the current system with respect to predevelopment conditions and effect of projected water demands increase on the resulting water deficits.

A surface water resources management model is developed using dynamic programming. The model inputs are the hydrological inflows from the different wadis in the project area, reservoirs characteristics and evaporation rates, system water demands. The model outputs are water deficits at the different demand areas, reservoirs storage and release sequences, water transfers and energy requirements and the associated costs. The average annual values of different performance criteria with the annual frequency curves are used to evaluate the implications of different water scenarios on the ISGP.

The results show the efficiency of the ISGP model in reducing the water deficits in the demand areas as compared to predevelopment conditions. Increased demand scenario showed the importance of finding new water projects to supplement the Southern Ghor Area in the future in order to meet the increasing water demands. The proposed water transfer will reduce the resulting deficits at the agricultural areas without the expenses of increasing the water deficits at other demand areas. The application of this model is expected to enhance decision making regarding water policies in Jordan.

This paper provides critical quantitative information to decision makers in Jordan about the potential of the different storage facilities and proposed transfers in meeting the required water demands in the Southern Ghor Project and assesses the required energy for that. This can help decision makers to have a holistic view about the expected water deficits in the area and therefore assist them in determining the areas impacted most and what alternative solution to use. The paper also shows the importance of using optimal control/management models to support water resources decision making in Jordan.
