Traditionally, wetlands were considered separately from river basin systems. However, nowadays it is becoming common practice to follow an integrated approach in wetland-riverine watershed analysis and management. Such approach requires not only adequate representations of all relevant bio-physical parameters, but also of socio-political and economic indicators. Data scarcity, an endemic problem in developing countries, hampers this global process. In this study, both conventional methods and state-of-the-art techniques and data sources are explored. A modelling framework is developed which includes rainfall-runoff processes, river hydrodynamics and water allocation models, seeking a balance between sophistication and simplicity, in view of data availability conditions. The framework was used to evaluate a number of scenarios, including potential effects of climatic variations and of the major hydraulic works that are planned by the national water authority. Several management options were assessed through this tool. In addition, special indicators were developed to remedy the lack of sufficient quantitative information by using a qualitative approach based on expert elicitation and stakeholder involvement. A decision support framework was applied to achieve a final ranking of the various management solutions that are in compliance with the national policies, facilitating the further development of management guidelines for wetlands across the Ecuadorian lowlands. The book will be of interest to water managers, hydro-informaticians/water modellers, people working at river basin authorities and Ministries of the environment.

Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems are of immense socio-economic as well as ecological importance. In this research, the focus was on the Abras de Mantequilla (AdM) wetland in the tropical coastal region of Ecuador, a RAMSAR site and case study area for the EU-FP7 WETwin project. The research in this thesis involves a combination of field data collection, multivariate analysis techniques, as well as numerical modelling studies. The goal was to explore the effects of changes in hydrological forcing on the hydrodynamic and ecohydraulic responses of the wetland. The study aims to contribute to the understanding of how a tropical river-wetland system functions in terms of hydrodynamics, water quality, primary production, and biotic communities. Spatial patterns of biotic communities and environmental variables are obtained as well as spatio-temporal variability of hydrodynamics, water quality, primary productivity and fish habitat-suitability conditions. In data scarce areas and countries with financial constraints, the combination of field measurements with numerical models was extremely useful and relevant, confirming that these techniques complement each other in obtaining a better understanding of the dynamics of freshwater river–wetland systems. Studies like the present research can be used to enhance awareness about the environmental services of wetlands and stimulate cooperation between all stakeholders in order to achieve more sustainable wetland management.

Integrated River Basin Governance - Learning from International Experience is designed to help practitioners implement integrated approaches to river basin management (IRBM). It aims to help the coming generation of senior university students learn how to design IRBM and it provides current researchers and the broader water community with a resource on river basin management. Drawing on both past and present river basin and valley scale catchment management examples from around the world, the book develops an integration framework for river basin management. Grounded in the theory and literature of natural resources management and planning, the thrust of the book is to assist policy and planning, rather than extend knowledge of hydrology, biophysical modelling or aquatic ecology. Providing a classification of river basin organizations and their use, the book also covers fundamental issues related to implementation: decision-making. institutions and organizations. information management. participation and awareness. legal and economic issues. integration and coordination processes. building human capacity. Integrated River Basin Governance focuses on the social, economic, organizational and institutional arrangements of river basin management. Methods are outlined for implementing strategic and regional approaches to river basin management, noting the importance of context and other key elements which have been shown to impede success. The book includes a range of tools for river basin governance methods, derived from real life experiences in both developed and developing countries. The successes and failures of river basin management are discussed, and lessons learned from both are presented. The ebook for this title is available to download for free on the WaterWiki.

Integrated river basin management is an approach focusing on the development and management of land and water resources in a coordinated manner with the primary aim to ensure society development, which is well balanced from the environmental, economic, and social points of view. It is a complex approach, including all aspects of water resource management (water and aquatic ecosystem protection, disaster management, and water use) and covering a wide range of disciplines (e.g., hydrology, ecology, environmental management, and economy), cross-cutting issues (climate change, data sharing, and stakeholder involvement), and approaches (river basin management plans preparation, water-food-energy-ecosystems nexus assessment, science-policy integration, and transboundary cooperation). This book provides a comprehensive overview of achievements and challenges associated with the implementation of the approach throughout the world.

This book compares the lessons learned from a wetland-perspective approach to the changing climate and the requirements of the Water Framework Directive (WFD) with regard to environmental conservation. Examples from Germany and Poland are discussed due to the efficiency of their respective implementations of water conservation policies. Although the general scientific interest in specific issues such as wetlands, climate change, nature conservation and the WFD enjoy a well established position in international environmental research, these four elements are rarely considered together due to the complexity of the processes, biased scenarios of global change and subjective policy background. Major challenges involved in carrying out environmental conservation actions that assess the potential impacts of climate change and management plans on water bodies are identified. The results of this approach are addressed to practitioners in the field of adaptive management in a wetlands context.

Establishing multi-scale optimal water allocation modes which takes the enhancement of utilization efficiency as core is a research hotspot for the international water resources management of river basins. This book aims to introduce how to compile the first set of county-level IO tables involving resources and environment accounts with integrated datasets which contains the spatio-temporal data of water and land resources, ecology and social economy in the river basin and to construct an integrated Computable General Equilibrium (CGE) model with resources and environment accounts embedded, which can be used to quantitatively depict the key process parameters of the water-ecology-social economy coupling system. Thus, this book can provide decision support for integrated river basin management, and scientific support for the sustainable development of social economy, eco-environment and water resources.

Decentralization and increased stakeholder involvement have been major elements of water sector reform as ways to promote sustainable and integrated resource management particularly of river basins. Based on an analytical framework for relating decentralization and stakeholder involvement to improved river basin management, this paper infers several hypotheses about factors associated with greater or lesser likelihood of success of the decentralization process using data from 83 river basins worldwide. The results suggest that physical, political, economic, financial, and institutional characteristics of the basin do affect the process and the level of performance of the decentralization. In particular, the presence of water scarcity may be a stimulus to reform, uniting the stakeholders in the basin and leading to better performance; organized user groups push for the initiation of decentralization reforms but may be associated with costs to the process and difficulty of achieving decentralization; the existence of dispute resolution mechanisms supports stakeholder involvement and improves decentralization performance; where stakeholders accepted greater financial responsibility, complying with tariffs and contributing to the budget for basin management, the decentralization process and performance measures increased; basins with higher percentages of their budgets from external governmental sources benefited from better stability and support and it shows in the performance of the decentralization process.

This volume examines the integration of water resource management for sustainable utilization with the optimum allocation of water use for regional economic development. It also contributes to the research on water resource management under climate changes and environmental adaptation. It will be a handbook for all researchers studying on integrated river basin management. Our book covers detailed research methods, issues, and frontier research questions and our answers for all people who are interested in this research direction. Particularly, socio-economic transaction of water use management is highly relevant to people’s daily life and their quality of life with environmental challenges. Academic contribution of this book will be technically explanation of terms, relationships, linkages, and consequence of environmental degradation from the tangent of integrated water management. Hence, it will offer many chances to the scientists, economists, sociologists, and other scholars from different subjects. Theories and methods to be addressed in this book are supposed to distinguish research mechanisms within various complex systems. Some research findings based on the extended input-output table nested by accounting of water and land will be introduced to show economic interdependence in a regional economic system, and its consequence under different designed scenarios will be discussed for broaden readers’ visions of the research in this field.An overview analysis on existing challenges and opportunities in some certain resource-limited areas has considerable potentials of improvement on integrated water management for regional green development. Our book will discuss many natural resource but focus on two natural resources including the water and land resources issues for studying a conceptual framework of integrated water management.

For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.
