This paper explores the concept of meaningful participation in river basin management, using the case study of the Hennops River in Gauteng Province, South Africa. Experiences of different stakeholders and communities regarding their involvement in the management of the Hennops River basin are analysed following engagement through interviews, workshops and clean-up initiatives. Several barriers and enablers for meaningful participation, such as lack of awareness, capacity, coordination, trust and incentives, are identified. Some recommendations are proposed for improving stakeholder and community participation, based on the lessons learned from the case study. This includes the formulation of a social fund to support small community-based projects such as clean-up campaigns. Projects should be reflective, keeping the community engaged and active. The paper argues that meaningful participation requires not only formal mechanisms of engagement and decision-making but also informal and practical actions that empower stakeholders and communities to take ownership and responsibility for their water resources and environment. For meaningful participation to take place, more needs to be done to shift communities away from a ‘bystander’ position to a more active role. A new approach to community engagement is therefore necessary to support stakeholder-driven initiatives and the raising of awareness in poorer communities. [ABSTRACT FROM AUTHOR]

Dams significantly impact the environment, industries, residential areas, and agriculture. Efficient dam management can mitigate negative impacts and enhance benefits such as flood and drought reduction, energy efficiency, water access, and improved irrigation. This study tackles the critical issue of predicting dam occupancy levels precisely to contribute to sustainable water management by enabling efficient water allocation among sectors, proactive drought management, controlled flood risk mitigation, and preservation of downstream ecological integrity. Our research suggests that combining physical models of water inflow and outflow "such as evapotranspiration using the Penman–Monteith equation, along with parameters like water consumption, solar radiation, and rainfall" with data-driven models based on historical reservoir data is crucial for accurately predicting occupancy levels. We implemented various prediction models, including Random Forest, Extra Trees, Long Short-Term Memory, Orthogonal Matching Pursuit CV, and Lasso Lars CV. To strengthen our proposed model with robust evidence, we conducted statistical tests on the mean absolute percentage errors of the models. Consequently, we demonstrated the impact of physical model parameters on prediction performance and identified the best method for predicting dam occupancy levels by comparing it with findings from the scientific literature.

Damming can promote flood control, water supply, power generation, and shipping but often changes the downstream hydrological regimes, producing adverse externality effects. Maximizing downstream social and ecological benefits will inevitably reduce upstream power generation. This study presents two novel bi-level hybrid game models, called the non-cooperative hybrid game model (NCHG) and the cooperative hybrid game model (CHG), to facilitate integrated water resource management in reservoir systems. The performance index of propensity to disrupt is applied to evaluate the stability of CHG, and an improved reliability index and Gini coefficient are adopted to evaluate the reliability and equity of both two models. The Three Gorges Reservoir and its adjacent cities were chosen as a case to inspect the two models' performance. A range of scheduling schemes was derived by proposed bi-level hybrid game models in wet, normal, and dry years. Results reveal that (i) the RI values of the watershed system obtained by the CHG are less than those in NCHG in three typical years (for example, 0.1201 VS 0.1930 in the wet year), showing higher systemic reliability. The Gini coefficients of the watershed system obtained by the CHG are all less than those obtained by the NCHG in all typical years (for example, 0.1016 VS 0.1020 in the wet year), which shows better performance of CHG on fairness for the allocation results; (ii) in the case of a multi-function reservoir system, the CHG generates favorable allocation schemes with higher systemic characteristic values by 32.43, 34.39, and 33.54 in wet, normal, and dry years, respectively, than those in NCHG (32.03, 33.16, and 31.42 in wet, normal, and dry years, respectively); (iii) compared with NCHG, the economic benefits obtained by CHG decreased by 0.98%, 1.04%, and 5.42% in wet, normal, and dry years, respectively; the social negative benefits decreased by 3.49%, 9.84%, and 28.69%; and the ecological negative benefits decreased by 1.77%, 5.65%, and 5.59%, respectively. It indicates that a minor sacrifice of the reservoir benefit could significantly improve the welfare at the system level by the CHG. The developed CHG can provide optimal water scheduling schemes in balancing inter-regional water conflicts and can be widely used to produce an equilibrium management strategy for a multi-function reservoir system.

Effective and sustainable water resource management requires flexibility and adaptation to local contexts. Our study analyzes the emergence and evolution of local water self-governing associations, reviewing how their struggles and conflicts, both with the public sector and among locals themselves, have been pivotal to achieving agreements and actions towards sustainable water management. Using an adapted version of the Combined Institutional Analysis and Development (IAD) and social–ecological system (SES) framework, also known as CIS, we conducted a comparative analysis of two distinct Chilean cases. This research highlights the critical role of historical factors alongside institutional support, political landscapes, and financial realities in shaping current water management practices. The findings suggest that when the actors are aligned and actions are taken to support local water user management, more efficient, sustainable, and less conflict-ridden water resource management occurs. Furthermore, this study reveals how the experiences, struggles, and successes of these local user associations have shaped national policies, particularly regarding the development of monitoring mechanisms and the promotion of public–private cooperation in water governance. These efforts have not only fostered more resilient water management systems but have also demonstrated the power of grassroots organizations in shaping broader sustainable policies.

The contribution of citizen scientists to environmental monitoring is notably increasing significantly. Governments worldwide establish Water Users Associations (WUAs) as a good practice model to implement Integrated Water Resource Management (IWRM) at local levels. These associations target different stakeholders depending on the expected outcome. However, their effectiveness, especially in East Africa, can only be determined case by case. In Kenya, Water Resources Users Associations are registered, voluntary community groups whose members are water users and land owners. Similarly, in Uganda, community-based initiatives exist, especially along degraded rivers, involving cooperation between local communities and regional water authorities. On the contrary, it has been reported that in Tanzania, many community initiatives created become non-functional within 2-3 years of induction. In general, the main responsibility of Water Users Associations or its equivalent is to manage and conserve water resources for sustainable uses. In most cases, water quality monitoring by communities through citizen science is limited to the visual appearance of water in the river channel. While this can indicate the water's esthetic value, it is insufficient for assessing the ecological status of rivers, which is influenced by a variety of physical, chemical, biological, and socioeconomic factors. The use of bioindicators has been advocated as a feasible method for community-based water quality river monitoring. Therefore, this review explores the commonly used bio-indicators and bio-assessment tools for river health assessment and their complexities when using a biomonitoring community-based approach through citizen science. Tolerance and intolerance macroinvertebrate and fish metric protocols that utilize identification keys have been recommended. These protocols are designed to be user-friendly and require minimal taxonomic expertise, making them easy for community volunteers to use with minimal basic training. The sustainability of these citizen science initiatives relies on the motivation of volunteers, the frequency of monitoring activities, and collaboration with researchers and government agencies. These initiatives not only facilitate environmental monitoring but also foster community engagement and awareness regarding the ecological status of rivers, thereby addressing knowledge and data gaps necessary for effective policy-making. This approach provides a practical model for environmental stewardship and participatory resource management in East Africa. [ABSTRACT FROM AUTHOR]

Twenty first century faces unprecedented challenges for the management of global waterways. The Himalayan waterways in Asia are exposed to unpredictable climatic warming together with anthropogenic perturbations caused by population growth, land use change and socio‐economic development. Given the increased public concerns on the Himalayan Mountain development programmes including the hydropower and tourism, there has been a growing need of the use of interdisciplinary scientific approaches to address water resources challenges that the Himalayan region has faced during the 21st century. Ecohydrology is an emerging scientific tool that explores key hydrological processes regulating structure and function of ecosystems, as well as assessing the impact of biological processes on water cycle variables under rapidly changing environment. The International Geosphere‐Biosphere Programme and the International Hydrological Programme hosted by the United Nations Educational, Scientific and Cultural Organization have adopted ecohydrology as a sustainable development tool by linking water resources and poverty eradication and ecosystem restoration, irrigation, energy and sanitation. However, ecohydrology tool needs to be reconfigured for sustainable development of rapidly changing Himalayan waterways. Here we propose the advancement of ecohydrology by developing various integrated frameworks of ecology, hydrology, hydraulics and sociology for resilient waterways in the Asian Himalayas.

Water issues have become complex and interconnected with many factors and sectors, making them too large to be handled by one single institution. Water problems can no longer be resolved solely by water professionals, the water science they provide is essential to resolve the water crisis, but the effectiveness of the solutions depends on the capability of the scientists to provide new, logical and practical visions to improve water systems, governance and communication. As part of Integrated Water Resource Management and Public Participation the current research aimed to address the knowledge gap that exists between the General Public and the Scientists by using applied theater, particularly empatheater to improve how scientific information is communicated. R-Studio was used to evaluate the effectiveness applying theater to communicate and educate the community on water resource management. Results revealed that using art to convey science is an effective environmental communication tool highly recommended by the participants to promote public participation in the rehabilitation of the Kaalspruit River.

Water reuse becomes an alternative to reduce the demand in the conventional water supply systems, especially in regions, where non-potable use of drinking water, as for garden and grass irrigation, is predominant. This study evaluates the footprint of reuse on small water supply systems in rural areas, where raw water quality does not meet the drinking water standards and complicated treatment is needed. Individual facilities for reuse of potential rainwater, light gray, gray and domestic wastewater in the households could lead to a decrease in non-potable tap water use up to 60% and a decrease of households' annual expenses for water supply up to 93 €/household. The installation of individual facilities for common reuse of rainwater and gray wastewater requires the highest investment costs, but the option`s operational costs are between 15% and 20% lower than all other options considered. The Drinking Water Treatment Plant capacity reduction due to Integrated Water Resource Management measures implementation enables from 48% up to 58% saving in the total operational costs for drinking water supply in the settlement. The shortest payback period and best economic impact of reuse for small scale water supply systems is observed if rainwater and gray wastewater are reused together. HIGHLIGHTS Annual water balance of the households in selected pilot site.; Estimation of drinking water use reduction due to the implementation of selected integrated water resource management (IWRM) measures.; Impact of the selected IWRM measures on the settlement drinking water treatment plant capacity.; Payback period analysis of IWRM based on capital expenditure and operating expenses.;

This article explores the concept of integrated water resources management (IWRM) and its development over the past 30 years. IWRM emerged in 1992 at the Dublin International Conference on Water and the Environment as a way to address the growing pressures on water resources by integrating environmental, economic, and social dimensions. However, early criticisms of IWRM pointed out its lack of clear definitions and practical implementation. To address this, the International Network of Basin Organizations (INBO) was established in 1994, proposing a definition and key actions for successful implementation. These actions include managing surface water and groundwater together, documenting water resource status, developing management plans, investing in measures, implementing sustainable financing mechanisms, and involving users and stakeholders. The article emphasizes the cyclical and iterative nature of the IWRM process and highlights the adaptability of the French water management model. The INBO has published manuals providing guidance and case studies for implementing IWRM in different contexts. The article also discusses the increasing role of IWRM at the basin level, highlighting governance and on-the-ground indicators that can be used to assess progress and challenges. The European region has been instrumental in promoting IWRM, with the adoption of the Water Framework Directive in 2000. International law, such as the Helsinki Water Convention, has also played a significant role in establishing a legal framework for cooperation on transboundary watercourses. The document stresses the importance of political and financial support for IWRM at the basin level [Extracted from the article]

Following the adoption of the Water Convention in Helsinki in 1992 and the Water Framework Directive in 2000, states located within a transboundary river basin were invited to set up basin organizations. The International Meuse Commission (IMC) was set up in 2002, under an agreement between France, Luxembourg, Germany, Belgium and the Netherlands. Over the last 20 years, the IMC has been a forum for exchange, coordination and cooperation between the riparian countries, leading to improvements in the water quality of the Meuse, reduction of obstacles for migratory fish, and establishment of cross-border systems to prevent accidental pollution and flooding.

Context: Contemporary resource management paradigms within the developed world build on an understanding of human agency as ontologically distinct from the mode of existence of plants and animals. Because of this perspective, which gives priority to human agency, policies typically take their point of departure with human societies and associated ecosystems deemed of particular value. Objectives: As an alternative to this worldview, social theorists have introduced what is known as "flat ontology", where all beings are bestowed equal rights to negotiate their existence. To explore the implications of introducing such an understanding into landscape management, a participatory planning process for water allocation was developed and tested in a case study in the Eerste River Catchment in South Africa. Methods: The planning process was mediated using the approach "politics of nature" (PoN), which aims to operationalize flat ontology to renegotiate water allocation based on the needs of all beings instead of the desire of a subset of humans. PoN allowed participants to playfully co-develop a common ontology and value-set. Data documenting these processes were collected digitally and analysed. Results: Results indicate that the approach engendered a rethinking of key relationships between human agency and ecosystem functionality, illustrating a potential for PoN-approaches to be deployed for governance of complex landscapes. Conclusions: On the basis of experiments using PoN-methodology in the context of watershed management, it is discussed how the introduction of a flat ontology in landscape research, could inspire new ways of designing and intervening with collaborative resource management processes.

Abstract The integrated management paradigm proposes dealing with a resource, such as water, considering its interrelationships with other environmental components. This vision has been adopted as a policy in several countries, including Colombia, but its results have not been satisfactory. This article studies the “integrative” approach in previous regulatory arrangements, making a historical review of them to understand how the perception and management of the environment by societies in Colombia have evolved. We show how the notion of a complex and integrated environment is not exclusive from current policies but has been present in the laws for several centuries, so its consideration does not guarantee success. Strategies are proposed to improve the results of recent regulatory arrangements.

IntroductionThe Water Flow Diagram (WFD) is a novel advocacy and communication tool that presents urban water supply and management in a simple visualization. Rapid urbanization, growing populations, and the climate crisis increase the pressure on water resources, particularly in urbanized areas. The WFD aims to foster a dialogue around conflict of interests and opportunities among different stakeholders, and trigger actions toward more sustainable urban water management (UWM), as well as a water secure future.MethodThe WFD is produced from data on water abstraction, water use of different sectors, water treatment, water recycling and contamination risks. The data were obtained from government services, wastewater and water utilities, large industries, universities and reports of intergovernmental organizations. If these sources did not have data, reports from NGOs or consultants, comparable contexts, default values or expert judgements were considered. The annual water flows are presented in a Sankey Diagram. An intuitive color code highlights the flows as “problematic” or “appropriate” and points to areas where UWM practices should be improved.Results and conclusionsThe final diagrams are a concise instrument that identifies challenges of UWM in the four application cases presented in this article. Key challenges that became evident included: pollution from agricultural production, the lack of wastewater and sanitation infrastructure, high water losses in the distribution networks, water exports leading to a lack in local supply and sewer overflows during heavy rainfalls. Opportunities identified were the need to: invest in sanitation and wastewater to protect resources, create coordination bodies to align conflict of interests, and/or invest in blue-green infrastructure for rainwater retention. The WFD triggered local actions, such as in-depth discussions between relevant actors, the formation of integrated water use committees and the interest of the national ministry in Senegal to replicate the diagram for other locations. This article presents the methodology, discusses the four case studies and deliberates on the prospective use of the WFD.

Water quality and quantity decline due to anthropogenic factors and climate change, affecting 2.3 billion people in water-scarce areas, of whom 733 million reside in Asia, Africa, and Latin America. Therefore, this review paper examined sustainable global water management by focussing on four sustainable development goal (SDG #6) indicators, including water use efficiency in agriculture, integrated water management, transboundary water cooperation, and water user participation. The review covered articles from 2016 to 2023, using Scopus and Web of Science databases with specific selection criteria. A total of 216 sources were downloaded, and after data screening, 72 articles were analysed along with additional supplementary materials such as books, conference papers, and United Nations documents. The finding indicates emerging trends in sustainable water management for agriculture, including water-efficient technologies like alternate wetting and drying, drip irrigation, mulching, etc. However, careful implementation is required to address environmental concerns, prevent water pollution, minimise yield reductions, and ensure long-term sustainability. Moreover, integrated water resource management has faced challenges in practical implementation due to governance structures, economic circumstances, cooperation, and collaboration among stakeholders. While over 600 treaties aim to promote international water cooperation, only a few have been effective. In addition, out of 500 transboundary groundwater sources shared by countries, only six have dedicated treaties to govern their use. Thus, clearly defined rights, responsibilities, and sustainable management practises for each shared aquifer would foster the sustainability of these resources. Moreover, engaging communities through inclusive policies, dialogue, and empowerment is vital for sustainable water management. Investment in community education and capacity-building fosters transformative change and addresses global water management challenges, securing the future of precious water resources.

This paper responds to the significant challenges to Integrated Water Resource Management (IWRM) and clarifies its practical value as a theoretical framework. Through thorough theoretical analysis, this paper examines how IWRM can be applied to distinguish water resource management (WRM) as an observable domain with an open boundary and foster sustainable ecosystem management by emphasizing the functional differentiation of WRM. Compared to the examination made solely from the WRM perspective, an IWRM perspective can better develop the structural complexity of the WRM domain and help expose misunderstandings regarding integration issues. Most importantly, IWRM is not merely an explanatory theoretical framework but also a defensive one. It can facilitate structural coupling between WRM and other domains to reduce conflicts and enable concerted action. However, this role of IWRM has been overlooked for a long time.

Interpretations of integrated water cycle management (IWCM) differ across jurisdictions. This paper discusses 10 interpretations of the IWCM concept globally, in Australia and in jurisdictions similar to Australia. Five interpretations of many IWCM versions in Australia are reviewed. This strategic concept aims to address the internal challenges of managing water demand and supply, achieving appropriate disposal and/or wastewater recycling for re-use and distribution networks and providing services at an affordable rate, per changing community needs. The IWCM concept is also recognised as a resource planning tool to address external challenges, such as the uncertainties of climate change, the circular economy and resilience. All 10 IWCM concepts reviewed in this paper acknowledge governance and stakeholders to be of primary importance: governance to drive the conceptual interpretation and stakeholders to develop, drive, implement and promote IWCM as adept at addressing local challenges. The two global interpretations place primary importance on governance, stakeholder engagement and natural resource management, whereas the local interpretations place equally high importance on water critical infrastructure and water economy. Technology, which is changing at an unprecedented pace, is considered, but not as an immediate or primary challenge. These differences are mainly attributed to the organisations' responsibilities and constraints, which drive IWCM concept design. [ABSTRACT FROM AUTHOR]

Urban waterways are an important part of urban ecosystems, and well-managed urban waterways can support diverse benefits to communities and nature. The literature suggests that collaborative engagement is a pathway to unlocking broader benefits. There is, however, an intention–implementation gap, limiting the adoption of community collaboration in urban waterways governance. This paper reports on two case studies based on interviews and analysed with the aim of better understanding the factors that cause this dilemma. The case studies are in Melbourne, Australia, and are examples of where such community participation practices have been attempted. Our analysis includes twenty-three semi-structured interviews from these two cases. Data were analysed using the Values–Rules–Knowledge framework, a heuristic to help decision-makers analyse how social systems shape decision contexts. The results from the case study highlight three key factors that hinder effective community involvement. Bureaucratic processes act as de facto gatekeepers, reinforcing existing power dynamics. Inclusivity is difficult to define and achieve, highlighting the limited availability of appropriate tools. Finally, implementing participatory practices is resource intensive in terms of time, staff skills, and funding, leading to inadequate resourcing. Overcoming these challenges requires a comprehensive change in bureaucratic procedures, choice of engagement methods, and improved resource management. [ABSTRACT FROM AUTHOR]

Water resources and economic growth are two preoccupations that take different senses. The overconsumption can be very costly in terms of the quantity and quality of water resources, which indulges many negative impacts on water reserves. In arid zones, institutions and large national firms are obligated to deliver more efforts in term of adaptation to the area’s hydraulic situation. In this work, we addressed the issue of integrating good governance of water resources into the decision-making process of large firms in Morocco. We studied the case of the Guemassa mine of the Managem group, located in the Tensift Haouz basin. In order to assess the efficiency of their strategy, we carried out an impact study of the company’s mining activities on the quality and quantity of the region’s waterresources and we provided key information on the hydraulic situation of the region in question. As a result, the company is monopolizing a large part of the water resources of the Haouz plain and their integrated water resource management strategy is deemed insufficient.

Whether pursuing the breadth of the UN's Sustainable Development Goals or delivering joined-up approaches within a single environmental domain, policy objectives, policy design and policy implementation should cohere vertically and horizontally. However, policy coherence remains a challenge to implement. The limited empirical scholarship on policy coherence tends to focus on policy documentation and/or the outcomes, with little attention to individual agency or social processes involved. Furthermore, there is little discussion of the normative dimensions of policy coherence and the political aspects of individual agency, indicating the need for political ecology. We conducted an empirical study within four UK catchment (watershed) partnerships, using critical interpretive policy analysis to enrich the interface between political ecology and environmental policy. We explored who practices policy coherence and how; what motivates those investing their energy into these practices; their constraints and the contradictions arising. We found that the appetite and ability to support policy coherence depends on individual agency as much as partnership structures, which are themselves situated in technocratic regimes of policy implementation. Within these regimes, agents presented as apolitical and enabling, making it challenging to research the political and social processes of policy coherence. A political ecology lens highlights how power is involved in these voluntary initiatives, potentially shoring up existing privilege inscribed into riparian habitats and their resources. Our contribution therefore responds to and amplifies the critique of traditional presentations of integrated water resource management devoid of politics.

Models provide invaluable visions to decision-makers for basin-scale management of water resources. However, decision-makers have difficulties in directly using these complex models. Water managers are primarily interested in user-friendly features allowing an integration of their judgments into the decision-making process, rather than applying detailed theories and methodologies. This knowledge gap between technical simulation models and policy-makers highlights the urgent need for developing an integrated water resource management decision support system (IWRM-DSS). This paper describes the main aspects of a new IWRM-DSS in which Microsoft Visual Studio under the C# language was employed to integrate the Microsoft SQL server as a database and ArcGIS Engine DLLs for pre/postdata processing for the SWAT and MODFLOW models. Two particular ‘module’ and ‘presentation’ shells are specifically designed for decision-makers to create four different scenarios, namely, ‘climatic’, ‘recharge’, ‘discharge’, and ‘coupled’ and to analyze the results. Decision-makers, without any detailed modeling knowledge and computer skills, can access the data and run models to test different management scenarios in an attractive graphical user interface. The IWRM-DSS, which was applied for the Neishaboor watershed, Iran, reveals that mean annual potential evapotranspiration increased to 8.2%, while runoff and recharge rates are reduced to 35 and 63%, which led to a decline of 13.5 m in mean groundwater level for the 13-year projected period. HIGHLIGHTS Decision-makers have difficulties in directly using complex simulation models.; Decision-makers prefer the integration of their judgments into the decision-making process.; A scenario-based coupled SWAT-MODFLOW Decision Support System was developed.; Decision-makers can test different scenarios without any detailed modeling knowledge.; The DSS was efficient to engage stakeholders in the water resource management process.;

Afghanistan has abundant water resources; however, the current state of affairs is dismal because of the lack of integrated water resources management (IWRM) practices and prolonged war and conflict in the country. Therefore, there is a need for a systematic approach to water management, which can be materialized by integrating IWRM and the water–energy–food (WEF) nexus approach to maintain a critical balance of available water resources and their various uses at the national level. This study provides a comprehensive assessment of Afghanistan's water resource management, including the current state, challenges, opportunities, and way forward. The identified challenges are categorized as social and environmental issues, engineering and technical and regulatory, policy and government role. These challenges are inter-connected and a novel framework toward the implementation of IWRM and the WEF nexus in Afghanistan is proposed. This framework can be used by the relevant stakeholders to prepare a roadmap for sustainable management of water resources. Such integrative approaches will enhance Afghanistan's water, food, and energy security and significantly contribute to its economic development. Moving forward, the Afghanistan government must play a crucial role with regards to the efficient management of the country's water resources in an integrated manner as suggested in this paper. HIGHLIGHTS Critical assessment on Afghanistan's water resources development.; Challenges to Afghanistan's water resources development are inter-connected.; A novel framework and multisectoral approach toward the implementation of IWRM and the WEF nexus in Afghanistan is proposed.; Enhancing IWRM and WEF nexus may eradicate hunger as the agriculture sector is disconnected with water, land, and energy sectors.;

Torrents play an essential role in water resources through rainfall in arid to semi-arid mountainous regions, serving large populations worldwide, and are also crucial in maintaining the downstream environment. The natural flows (floods, ephemeral flows) in arid hill regions result in potential hydrological fluctuations caused by climate change. However, the feasibility of eventual storage in remote hilly catchments would force a more sudden change. The current study was conducted in the lower part of the Khirthar National Range in the Sindh province of Pakistan, with the aim to explore spatial runoff storage sites for sustainable development to mitigate the impacts of climate change in arid areas. In total, 83 years of precipitation data were used to estimate water availability, along with satellite imagery for LULC pre- and post-monsoon conditions, delineation of watersheds, and identification of potential runoff storage locations and return periods, using Remote Sensing (RS)/Geographical Information System (GIS) 10.5.1, HEC-HMS 3.1, and Origin Pro 9.0 for statistical approaches. The model delineated two potential watersheds: Goth Sumar, covering an area of 61.0456 km2, wherein ten cascading reservoirs were identified, and Goth Baro, covering an area of 14,236 km2, wherein two cascading reservoirs were identified. Different storage capacities were determined for the cascade-type reservoirs. The maximum live volumetric potential storage of the reservoirs varies from 0.25 to 1.32 million cubic meters (MCM) in the villages of Baro and Sumar. The return periods have been estimated at 5, 10, 20, 25, 50, and 75 years, corresponding to 12.35, 16.47, 21.43, 21.72, 25.21, and 40.53 MCM for Goth Sumar, while Goth Baro's storage capacity has been estimated at 2.88, 3.84, 5.00, 5.06, 5.88, and 9.45 MCM, respectively. All results obtained were authenticated using accuracy assessment, validation, and sensitivity analysis. The proposed potential storage sites were recommended for a planning period of five years. The live storage capacity of the identified cascade reservoirs can be improved by raising the marginal banks and developing the spillways to control inlet and outlet flow in order to maintain internal pressure on the reservoir banks. The stored water can be used for climate-friendly agricultural activities to increase crop production and productivity. The proposed study area has extensive experience with flood irrigation systems and rainwater harvesting to sustain agriculture due to rainfall being the only water resource (WR) in the region. However, the study area has enormous potential for surface runoff WRs, especially during the rainy season (monsoon); the current 2022 monsoon is showing flooding. The modeling approaches of Remote Sensing, GIS, and HEC-HMS play an important role in delineating watershed areas, developing hydrographs, and simulating water availability for different return periods by minimizing cost and time.

Interlinking rivers (ILRs) is a recent global initiative towards sustainable and equitable distribution and utilization of water resources. However, there are diverse, uncertain, and conflicting viewpoints of various water resource planning and management stakeholders towards ILR approach and its outcomes. On one hand, policy makers are seeing ILR as advantageous to the economic development of the nation; on the other hand, there is a growing concern about the negative environmental impacts of ILR. To ensure sustainable development, watershed planners across the globe need a decision support system (DSS) to effectively plan the implementation of ILR projects while considering the diverse stakeholder's perspectives and conflicting socio-economic, environmental, and several technical criteria. Therefore, it is essential to identify and mathematically evaluate the strengths, weaknesses, opportunities, and threats (SWOT) of ILR projects to achieve economic and environmental objectives. It is indeed a challenge for watershed managers to simultaneously address the uncertainty associated with multiple criteria and group of decision-makers (stakeholders) involved in developing the SWOT model. To address these concerns, the present study proposes an advanced entropy-based SWOT fuzzy decision support system to evaluate the feasibility of ILR on a case study of 'Ken-Betwa project', India. The novel aspect of the advanced approach is its ability to devise seven hybrid mechanisms, which give the flexibility to reach the best solutions along with nominal, optimistic and pessimistic perspectives of the stakeholders while addressing uncertainty issues. Results demonstrate that adopting measures to minimize impact on biodiversity and climate change and implementation of sustainable construction techniques are pivotal for successful implementation of ILR project with a score of 0.12 and 0.11, respectively. The DSS provides a platform to the state and federal agencies to systematically achieve socio-economic and environmental objectives while incorporating suggestions of all decision-makers towards ILR projects.

Rivers and their surrounding lands are focal points of human development in the landscape. However, activities associated with development can greatly affect river processes, causing significant and often unintended environmental and human impacts. Despite the profound and varied environmental impacts that development-related alterations cause through hydrological, geomorphic, and ecological processes, they are not widely acknowledged outside of river management and affect resource availability and hazard exposure to people. In this paper, we propose a novel, interdisciplinary conceptual framework of river–land process interactions to support sustainable management and development. We introduce the term 'land–river interface' (LRI) to describe areas of the landscape in which river processes affect land, vegetation, and/or fauna, including humans, directly or indirectly. The multiple links between LRI processes and factors at the river basin, valley, and river channel (i.e. reach) scale are synthesized and a conceptual zonation of the LRI based on the process is proposed to serve as a framework to understand the impacts of human activity. Three examples of development-related activities (urbanization, dams and aggregate mining) illustrate how alteration to the form and functioning of river basins, valleys, and channels cause a range of impacts to be propagated throughout the landscape, often spatially or temporally distant from the activity. The diversity and severity of these impacts on the environment and people underscore the need to incorporate river processes, as represented in the LRI concept, into broader environmental management to better anticipate and mitigate negative impacts and maximize positive outcomes to deliver the benefits of sustainable development across society.

Summary: Motivation: Water management is currently sustained by international norms negotiated in global meetings which are replicated worldwide. Integrated Water Resources management (IWRM) and the Human Right to Water and Sanitation (HRWS) are two of the main global norms presented as important ideals for good water governance, and as such are seen as contributing to achievement of the Sustainable Development Goals (SDGs). This article engages with this logic. Purpose: The article analyses two global water norms in Central America: the IWRM and HRWS, from their regional and national definitions and implementation in order to respond to the following research question: does the adoption of IWRM and the HRWS in Central American water management represent normative coherence for development or normative hegemony manifested by vertically imposed global water governance norms? Methods and approach: The research examines the definition and implementation of IWRM and the HRWS in the Central American Integration System (SICA) and six member states. It examines regional legal frameworks and national water laws and policies. Data collection included reviews of policy documents, academic studies, and grey literature from regional organizations and fieldwork conducted from 2012 to 2019. Findings IWRM and HRWS are global water norms that have been institutionalized in Central America through development co‐operation partnerships, especially with European donors. This research shows that SICA member states have not implemented these norms due to the opposition of diverse coalitions of water stakeholders, including agribusiness, economic elites, and indigenous communities. The findings indicate that stakeholder participation and normative legitimacy are the defining characteristics that separate normative coherence for sustainable development from normative hegemony. Policy implications: Despite Central America's legal alignment with the SDGs, significant grassroots opposition to the implementation of global water norms across the region suggests that normative coherence for sustainable development depends on normative alignment and incorporation by states in national legal frameworks but is also conditioned by stakeholder participation. These findings indicate that normative coherence for sustainable development should become more participative in nature in order to promote transformative development as defined by the SDGs. Otherwise, stakeholders may perceive it as normative hegemony. [ABSTRACT FROM AUTHOR]

Rapid population growth along with increased rates of economic growth around the globe are placing valuable natural resources, water in particular, under unprecedented stress; this in turn drives the pursuit of innovative tools to support integrated Water-Energy-Food (WEF) nexus management. This paper presents a framework for the integrated management of the WEF nexus, which brings together four separate models that address the less well-examined socio-anthropological aspects of the nexus. The proposed framework provides insight into the human element as part of the wider ecosystem in terms of socio-cultural and economic activities, the laws and policies that govern these activities, as well as their potential socio-economic impacts and consequences. This paper outlines each individual model, before going on to present a conceptual framework for the integration of the various models for the purpose of supporting more robust decision-making. The framework, which is grounded in systems thinking, adopts the principles of sustainable development as structural foci in order to position the various models in relation to one another; harmonizing their inputs as well as outputs.

Interpretations of integrated water cycle management (IWCM) differ across jurisdictions. This paper discusses 10 interpretations of the IWCM concept globally, in Australia and in jurisdictions similar to Australia. Five interpretations of many IWCM versions in Australia are reviewed. This strategic concept aims to address the internal challenges of managing water demand and supply, achieving appropriate disposal and/or wastewater recycling for re-use and distribution networks and providing services at an affordable rate, per changing community needs. The IWCM concept is also recognised as a resource planning tool to address external challenges, such as the uncertainties of climate change, the circular economy and resilience. All 10 IWCM concepts reviewed in this paper acknowledge governance and stakeholders to be of primary importance: governance to drive the conceptual interpretation and stakeholders to develop, drive, implement and promote IWCM as adept at addressing local challenges. The two global interpretations place primary importance on governance, stakeholder engagement and natural resource management, whereas the local interpretations place equally high importance on water critical infrastructure and water economy. Technology, which is changing at an unprecedented pace, is considered, but not as an immediate or primary challenge. These differences are mainly attributed to the organisations’ responsibilities and constraints, which drive IWCM concept design.

Models that can integrate aspects of society such as institutions, perceptions and behaviours with aspects of the natural system such as rainfall, runoff and water quality may help us understand and manage complex human–water systems. In this paper, a socio-hydrological model is developed for the Black Volta (Mouhoun) watershed in Burkina Faso. The model captures the relationships between the awareness of water quality issues and capacity of local organizations, land use in the riparian zone, agricultural practices and suspended sediment concentration as an indicator of water quality. Scenarios are generated for the current situation and for plausible pathways to achieve improved water quality through different riparian land management strategies. Scenario comparison show how water quality improvements are generated if institutional support, resources and capacity of local level organizations are substantially increased compared to current levels.

Water crises in Latin America are more a consequence of poor management than resource scarcity. Addressing water management issues through better coordination, identification of problems and solutions, and agreement on common objectives to operationalize integrated water resources management (IWRM) could greatly improve water governance in the region. Composite indices have great potential to help overcome capacity and information challenges while supporting better IWRM. We applied one such index, the Freshwater Health Index (FHI) in three river basins in Latin America (Alto Mayo, Perú; Bogotá, Colombia; and Guandu, Brazil) to assess freshwater ecosystem vitality, ecosystem services, and the water governance system in place. The approach included convening management agencies, water utilities, planning authorities, local NGOs and industries, community groups and researchers to co-implement the FHI. The results provide detailed information on the ecological integrity of each basin and the sustainability of the ecosystem services being provided. All three basins show very low scores for governance and stakeholder engagement, thus improving both in the region should be a priority. The results also shed light on how the FHI framework can help inform decision-making to improve IWRM implementation by facilitating stakeholder engagement while contributing to coordination, identification of problems and solutions as well as agreement on common objectives. Because implementation of IWRM is part of the solution for the United Nations Sustainable Development Goal (SDG) 6.5 ("By 2030, implement IWRM at all levels, including through transboundary cooperation as appropriate"), our case studies can serve as examples to other Latin American countries to achieve SDG 6.5.

Integrated water resource management contributes significantly in addressing the upsurge in water demands and challenges. The Global Water Partnership (GWP) defined the overall concept based on economic growth, accurate coordination, food security, health improvement, and social equity without compromising the sustainability system. Therefore, a need for consensus development and stakeholder involvement at every level becomes very paramount. However, the integration of sectoral organization within a particular river basin and effective management information appears imperative but complex to achieve due to political differences, individual interests, institutional influence, and objectives. The purpose of this study was to evaluate the sustainability of water resource management in Aceh Meureudu River Basin in a multidimensional and integrated approach by considering the social, economic, environmental, engineering, legal, and institutional frameworks. Furthermore, multi-dimensional scaling by a modified Rapfish software known as Rap-river basin was employed to calculate the percentage sustainability of several dimensions and reviewed attributes. The results of the MDS analysis on the Aceh Meureudu River Basin show the value of the sustainability of the technical (43.15), legal (43.07), and institutional (43.87) dimensions that fall into the less sustainable category. Some attributes do not indicate the direction of sustainable integrated water resources management. Value of sustainability the social (54.35), economic (53.40), and environmental (53.13) dimensions can be said to lead to the sustainability of the system even though the value is still low. Great efforts are needed to overcome this inequality so that the IWRM of the Aceh Meureudu River Basin is sustainable. [ABSTRACT FROM AUTHOR]
