This book addresses strategies for food security and sustainable agriculture in developing economies. The book focuses primarily on India, a fast developing economy, whose natural resource base comprising land and water supporting agricultural production is not only under enormous stress, but also complex and not amenable to a uniform strategy. It critically reviews issues which continue to dominate the debate on water management for agricultural and food production. The book examines the validity of the claim that large water resources projects cause serious social and environmental damages using global and national datasets. The authors examine claims that the future of Indian agriculture is in rain-fed farming supported by small water harvesting. They question whether water-abundant eastern India could become the granary of India, through a groundwater revolution with the right policy inputs. In the process, they look at the less researched aspect of the food security challenge, which is land scarcity in eastern India. The book analyzes the physical, economic and social impacts of large-scale adoption of micro irrigation systems, using a farming system approach for north Gujarat. Through an economic valuation of the multiple use benefits from tank systems in western Orissa, it shows how value of water from large public irrigation systems could be enhanced. The book also looks at the reasons for the limited success in bringing about the much needed institutional reforms in canal irrigation for securing higher productivity and equity using case studies of Gujarat, Madhya Pradesh and Maharashtra. Finally it addresses how other countries in the developing world, particularly Sub-Saharan Africa could learn from Indian experience.

For the Nonengineering Professional Perfect for anyone without a background in science or engineering who wants to take a closer look at how water is processed and treated, Reverse Osmosis: A Guide for the Nonengineering Professional relates reverse osmosis in its most basic form and addresses growing concerns about the quality of tap water. What is reverse osmosis? Not to be confused with filtration-which involves straining or size exclusion-reverse osmosis involves a diffusive mechanism and separation process that is dependent on solute concentration, pressure, and the water flux rate. This book describes all of the basic processes involved in reverse osmosis operations. Presented in a conversational style-using jargon-free language-it discusses in detail the drinking water purification, wastewater reuse, desalination processes, and other freshwater applications used to ensure the safe consumption of water. The book also places special emphasis on pharmaceuticals and personal care product (PPCP) contaminants, which are not typically removed from wastewater by conventional treatment processes, however, they can be removed by processes using sophisticated membrane filtration. The author provides a basic understanding of membrane technology, and explains the membrane treatment process. He details how the processes fit together within a drinking water or wastewater treatment system and presents concepts that make up water and wastewater treatment processes as a whole. He also highlights advances in reverse osmosis technology and discusses relevant applications. Presents a comprehensive coverage of reverse osmosis Discusses fundamental processes and equipment used in reverse osmosis Provides technical terminology in simplified form Reverse Osmosis: A Guide for the Nonengineering Professional explains how reverse osmosis

This study assessed the downstream river system adaptation in response to upstream damming on the Ribb River, Ethiopia, to irrigate 15,000 ha. It combined primary and secondary data, and the application of remote sensing and mathematical modeling. The pre-dam morphodynamic trends of the Ribb River were analyzed for 59 years based on aerial photographs, satellite images, and newly collected field data. Three dam operation scenarios were developed to analyze the long-term hydro-morphological effects of the dam on the downstream river reaches. It also assessed the applicability of physics-based analytical equations (Equilibrium Theory) compared to a 1D numerical model (SOBEK-RE) to determine the least-morphologically impactful dam operation scenario on the river reaches downstream of the dam. Moreover, a HEC-RAS 2D hydrodynamic model was developed to assess the effect of the dam on the flooding extent of the Fogera Plain. This was used to study the potential implications of hydrological alteration on the ecology of the floodplain wetlands, as they are the habitats of important fish and bird species. The results contribute to knowledge on the hydro-morphological and environmental impacts of dams on downstream river systems. The developed methodologies and findings may be used to study future hydro-morphological and ecological changes that may arise due to other dam operations or climate change.

This book focuses on River Basin Organizations as the key institutions for managing internationally shared water resources. This includes a comparative analysis of all River Basin Organizations worldwide and three in-depth case studies from three different continents. The detailed case studies are the Senegal (West Africa), Mekong (South-east Asia) and Danube (Europe) rivers. The book contributes to the academic debate on how shared natural and environmental resources can be managed in a sustainable way and which institutional and legal mechanisms actually matter for doing so. It adopts the neo-institutionalist approach, according to which international environmental institutions do make a difference. The analysis not only confirms this argument for the specific case of shared water resources, but also refines existing hypotheses on the influence of different independent variables, namely the nature of the collective action problem, the constellation of actors and the institutional design of an international environmental institution. The work also contributes to the policy debate on how to better govern internationally shared natural resources and the environment. It provides policy makers with advice on which exogenous conditions to be aware of when managing water resources they share with co-riparians and which institutional design features and governance mechanisms to set up in order to increase effectiveness in management.

This book accounts for the previously inadequately explained transformation in the meaning of equity in sixteenth century England, a transformation which, intriguingly, first comes to light in literary texts rather than political or legal treatises. The book address the two principal literary works in which the transformation becomes apparent, Thomas More's Utopia and Edmund Spenser's Faerie Queene, and sketches the history of equity to its roots in the Greek concept of epieikeia, uncovering along the way both previously unexplained distinctions, and a long-obscured esoteric meaning. These rediscoveries, when brought to bear upon the Utopia and Faerie Queene, illuminate critical though relatively neglected textual passages that have long puzzled scholars.

This title, first published in 1987, provides an authoritative account of both the science and the politics of acid rain. Chris Park places the debates surrounding acid rain in context, and examines the full implications of scientific studies and the effects of acid rain on surface waters, soils and buildings. Evidence is drawn from around the world, including an examination of the damage in Scandinavia and Germany and the effects of acid rain in the U.K. and U.S.A. A comprehensive and relevant work, this is an important guide for students of geography, environment and sustainability and energy policy.

This book presents recent lessons learned in the context of research and development for various dryland ecosystems, focusing on water resources management, land and vegetation cover degradation and remediation, and socioeconomic aspects, as well as integrated approaches to ensuring water and land security in view of the current and predicted climate change. As water and land are the essential bases of food production, the management of these natural resources is becoming a cornerstone for the development of dryland populations. The book gathers the peer-reviewed, revised versions of the most outstanding papers on these topics presented at the ILDAC2015 Conference in Djerba, Tunisia.

Sludge transportation costs can represent a large fraction of the expenses associated with municipal and faecal sludge management. These costs can be mitigated through the use of thermal drying approaches to reduce the sludge volume. This thesis described the application of a novel microwave-based pilot-scale unit as an alternative technology for the sanitisation and drying of sludge from municipal wastewater treatment plants and on-site sanitation facilities. The potential economic benefits of volumetric heating, moisture levelling, and increased liquid and vapour migration from the interior to the surface of the product underpins the increasing interest in the use of microwave technology during sludge treatment processes. According to the findings of this study, these factors lead to faster processing times, improved drying rates, and a reduced physical footprint. Furthermore, microwave technology operates as a standalone treatment unit. When coupled with mechanical dewatering techniques and membrane separation technology, it can increase the reliability of the technology employed in the treatment of sludge while recovering valuable resources through an agricultural or thermochemical application such as (co-) combustion. The results of this work demonstrate the strong feasibility of applying microwave-based technology within initiatives designed to protect the environment and safeguard public health.

The Hydraulic State explores the hydraulic engineering technology underlying water system constructions of many of the ancient World Heritage sites in South America, the Middle East and Asia as used in their urban and agricultural water supply systems. Using a range of methods and techniques, some new to archaeology, Ortloff analyzes various ancient water systems such as agricultural field system designs known in ancient Peruvian and Bolivian Andean societies, water management at Nabataean Petra, the Roman Pont du Garde water distribution castellum, the Minoan site of Knossos and the water systems of dynastic (and modern) China, particularly the Grand Canal and early water systems designed to control flood episodes. In doing so the book greatly increases our understanding of the hydraulic/hydrological engineering of ancient societies through the application of Complexity Theory, Similitude Theory and Computational Fluid Dynamics (CFD) analysis, as well as traditional archaeological analysis methods. Serving to highlight the engineering science behind water structures of the ancient World Heritage sites discussed, this book will be of interest to archaeologists working on landscape archaeology, urbanism, agriculture and water management.

The book also outlines hydrological processes in arid and semi-arid regions and hydrochemical properties of surface and groundwater as a necessary background for understanding how pollution impacts groundwater quality and resources, and how geographical modeling of hydrological processes can aid in human health risk assessments. The book is intended for academics, administrators, policymakers, social scientists, and professionals involved in the various aspects of climate change impact on groundwater quality, hydrological process, pollution mitigation strategies, sustainable development, and environmental planning and management.

The chapters in this book explore the range of physical and social attributes that have shaped and re-shaped our landscapes through time. International authors have contributed the latest results of investigating ancient landscapes (or "palaeolandscapes") in diverse settings of tropical forests, deserts, river deltas, remote islands, coastal zones, and continental interiors. The case studies embrace a liberal approach of combining archaeological evidence with other avenues of research in earth sciences, biology, and social relations. The chapters offer new perspectives on what the world's palaeolandscapes looked like, how people lived in these places, and how communities have engaged with long-term change in their natural and cultural environments though successive centuries and millennia. This book reaches across archaeology, ecology, geography, and broader studies of human-environment relations that will appeal to general readers. Specialists and students in these fields will find extra value in the primary datasets and in the new ideas and perspectives. It also provides unique examples from the past, toward understanding the workings of sustainable landscape systems.

Originally published in 1964, and extensively illustrated with figures and charts, this volume gives an overview of both physical and human geography of the former USSR.

This book describes pathogen removal processes in aerobic granular sludge (AGS) wastewater treatment systems. Faecal indicators (E. coli, Enterococci, coliforms and bacteriophages) were tracked in full-scale AGS facilities and compared to parallel activated sludge (CAS) systems. AGS showed similar removals as the more complex CAS configurations. Removal mechanisms investigated in laboratory-scale reactors showed that the AGS morphology contributes to the removal processes. By tracking E. coli and MS2, it was observed that organisms not attached to the granules are predated by protozoa during aeration. 18S RNA gene analyses confirmed the occurrence of bacterivorous organisms (e.g., Epistylis, Vorticella, Rhogostoma) in the system. Particulate material in the feeding stimulated their development, and a protozoa bloom arose when co-treating with (synthetic) faecal sludge (4 % v/v). An overview of the diverse eukaryotic community in laboratory reactors and real-life applications is also provided. The microbial diversity of the influent was different compared to AGS and CAS sludge samples. However, no clear differences were found between them on species level. This study contributes to a better understanding of the mechanisms behind pathogen removals in AGS systems.

This book reviews the current state of knowledge on, recent advances in, and future prospects of Montenegrin river basins in the context of anthropogenic activities. Edited by three respected experts in the field, the book begins with an introduction to the specific hydrogeological conditions in Montenegro and critical reflections on the impact of hydropower projects. It then reviews the vulnerability of river ecosystems, exploring potential genotoxic effects and water quality, and explaining typology and monitoring of these aspects, and particularly highlighting mollusk assemblages and monitoring of intermittent rivers. The closing chapters focus on the impact of river flooding and discuss controversial projects aiming to find an approach mutually acceptable to all stakeholders. Given its scope, the book is an indispensable resource for scientists in academia and the water industry, as well as for decision-makers in the field investigating the interactions between land and water, limnology and biota, and natural and cultural resources.

Flooding is one of the most frequently occurring and damaging natural disasters worldwide. Quantitative flood risk management (FRM) in the modern context demands statistically robust approaches (e.g. probabilistic) due to the need to deal with complex uncertainties. However, probabilistic estimates often involve ensemble 2D model runs resulting in large computational costs.Additionally, modern FRM necessitates the involvement of a broad range of stakeholders via co-design sessions. This makes it necessary for the flood models, at least at a simplified level, to be understood by and accessible to non-specialists. This study was undertaken to develop a flood modelling system that can provide rapid and sufficiently accurate estimates of flood risk within a methodology that is accessible to a wider range of stakeholders for a coastal city - Can Tho city, Mekong Delta, Vietnam. A web-based hydraulic tool, Inform, was developed based on a simplified 1D model for the entire Mekong Delta, flood hazard and damage maps, and estimated flood damages for the urban centre of Can Tho city (Ninh Kieu district), containing the must-have features of a co-design tool (e.g. inbuilt input library, flexible options, easy to use, quick results, user-friendly interface). Inform provides rapid flood risk assessments with quantitative information (e.g. flood levels, flood hazard and damage maps, estimated damages) required for co-designing efforts aimed at flood risk reduction for Ninh Kieu district in the future.

Climate change, combined with the rapid and often unplanned urbanisation trends, is associated with a rising trend in the frequency and severity of disasters triggered by natural hazards. In order to face the impacts of such threats, it is necessary to have an appropriate Disaster Risk Assessment (DRA). Traditional DRA approaches for disaster risk reduction (DRR) have focused mainly on the hazard component of risk, with little attention to the vulnerability and the exposure components. To address this issue, this dissertation's main objective is to develop and test a disaster risk modelling framework that incorporates socioeconomic vulnerability and the adaptive nature of exposure associated with human behaviour in extreme hydro-meteorological events in the context of SIDS. To achieve the objective, an Adaptive Disaster Risk Assessment (ADRA) framework is proposed. ADRA uses an index-based approach (PeVI) to assess the socioeconomic vulnerability using three components: susceptibility, lack of coping capacities, and lack of adaptation. Furthermore, ADRA explicitly incorporates the exposure component using two approaches; first, a logistic regression model was built using the actual evacuation rates observed during Hurricane Irma, and second, an Agent-based model is used to simulate how households change their exposure levels in relation to different sources of information

This thesis presents analysis of the status of IWRM implementation along with the challenges with regards to policy and institutional measures as well as the required basin information and management instruments. The research entailed a detailed analysis of water resources systems based on a case study from the Awash River Basin in Ethiopia, covering the historical and present state of the challenges and gaps in policies, institutional arrangements and management instruments. The status quo of practical water management, implications of plausible management alternatives in terms of their impact to future water availability, demand fulfilment, patterns of use, and sustainability of the environment were examined. Moreover, the interlinkages and dynamics between key water dependent resources sectors, broadly categorized into water, energy, food, and ecosystems (WEFE) was explored to identify key tradeoffs and synergies. This was deliberated as to improving the synchronization of sectoral plans and resources management programs, thereby fast-tracking the coordination process in IWRM. Overall, the research provides a clearer understanding of the system-wide problems, structural challenges and possible future consequences regarding the management and sustainability of the entire water resource system. Ultimately the purpose is to set in motion new strategies and mechanisms to improve the implementation of the currently applied IWRM framework in the context of the SDGs.

Award-winning journalist rafts down the Green River, revealing a multifaceted look at the present and future of water in the American West. The Green River, the most significant tributary of the Colorado River, runs 730 miles from the glaciers of Wyoming to the desert canyons of Utah. Over its course, it meanders through ranches, cities, national parks, endangered fish habitats, and some of the most significant natural gas fields in the country, as it provides water for 33 million people. Stopped up by dams, slaked off by irrigation, and dried up by cities, the Green is crucial, overused, and at-risk, now more than ever. Fights over the river's water, and what's going to happen to it in the future, are longstanding, intractable, and only getting worse as the West gets hotter and drier and more people depend on the river with each passing year. As a former raft guide and an environmental reporter, Heather Hansman knew these fights were happening, but she felt driven to see them from a different perspective-from the river itself. So she set out on a journey, in a one-person inflatable pack raft, to paddle the river from source to confluence and see what the experience might teach her. Mixing lyrical accounts of quiet paddling through breathtaking beauty with nights spent camping solo and lively discussions with farmers, city officials, and other people met along the way, Downriver is the story of that journey, a foray into the present-and future-of water in the West.

Studies of drought have increased in light of new data availability and advances in spatio-temporal analysis. However, the following gaps still need to be filled: 1) methods to characterise drought that explicitly consider its spatio-temporal features, such as spatial extent (area) and pathway; 2) methods to monitor and predict drought that include the above-mentioned characteristics and 3) approaches for visualising and analysing drought characteristics to facilitate interpretation of its variation. This research aims to explore, analyse and propose improvements to the spatio-temporal characterisation of drought. Outcomes provide new perspectives towards better prediction. The following objectives were proposed. 1) Improve the methodology for characterising drought based on the phenomenon's spatial features. 2) Develop a visual approach to analysing drought variations. 3) Develop a methodology for spatial drought tracking. 4) Explore machine learning (ML) techniques to predict crop-yield responses to drought. The four objectives were addressed and results are presented. Finally, a scope was formulated for integrating ML and the spatio-temporal analysis of drought. Proposed scope opens a new area of potential for drought prediction (i.e. predicting spatial drought tracks and areas). It is expected that the drought tracking and prediction method will help populations cope with drought and its severe impacts.
