Toxic substances threatens aquatic and terrestrial ecosystems and ultimately human health. The book is a thoughtful effort in bringing forth the role of biotechnology for bioremediation and restoration of the ecosystems degraded by toxic and heavy metal pollution. The introductory chapters of the book deal with the understanding of the issues concerned with the pollution caused by toxic elements and heavy metals and their impacts on the different ecosystems followed by the techniques involved in monitoring of the pollution. These techniques include use of bio-indicators as well as modern techniques for the assessment and monitoring of toxicants in the environment. Detailed chapters discussing the role of microbial biota, aquatic plants, terrestrial plants to enhance the accumulation efficiency of these toxic and heavy metals are followed by remediation techniques involving myco-remediation, bio-pesticides, bio-fertilizers, phyto-remediation and rhizo-filtration. A sizable portion of the book has been dedicated to the advanced bio-remediation techniques which are finding their way from the laboratory to the field for revival of the degraded ecosystems. These involve bio-films, micro-algae, genetically modified plants and filter feeders. Furthermore, the book is a detailed comprehensive account for the treatment technologies from unsustainable to sustainable. We believe academicians, researchers and students will find this book informative as a complete reference for biotechnological intervention for sustainable treatment of pollution.

This book investigates how actors organize in order to solve a water quality problem. Research on the use of environmental resources has mainly focused on the circumstances needed for users to self-organize or to maintain an already sustainable way of resource use. Few studies have investigated the reasons why actors start to cooperate when they are faced with an environmental problem. Actor networks in three regions of the Rhine catchment area are scrutinized regarding a) actors' cooperation pattern when managing an environmental problem; and b) the factors that trigger actors in a common-pool resource situation to initiate cooperation. Water quality policy is analysed in two European countries - Germany and Luxembourg - and one non-European country - Switzerland -, providing an overview of the distinctive measures applied in these regions aiming to tackle the water quality problem of micro-pollutants in river surface water. Applying the social-ecological system framework (SESF) devised by E. Ostrom and her colleagues and Social Network Analysis (SNA), the current book combines qualitative and quantitative methods to answer the question of why actors cooperate in the management process of an environmental problem like water pollution.

When it comes to water, we are fed a daily diet of doom and gloom, of a looming crisis: wars of the future will be over water; nearly one-billion people lack access to clean water; river basins are closed so there is no more water to be allocated despite ever-growing demand; aquifers are overdrawn to such an extent that a global food crisis is just around the corner and major cities, such as Bangkok and Mexico, are sinking. And let us not forget about pollution or vector-borne diseases.

The challenges for sustainable water management are massive. Yet, as shown in this book, there are many positives to be drawn from the southern African experience. Despite abiding conditions of economic underdevelopment and social inequality, people rise to the challenge, oftentimes out of necessity and through self-help, but sometimes through creative coalitions operating at different scales - from the local to the global - and across issue areas - from transboundary governance to urban water supply.

This first volume in the Off-Centre series argues that we must learn to see water and the region differently if we are to meet present challenges and better prepare for an uncertain, climate-changing future.

This book expands the body of scientific knowledge on research and solutions for alternative water systems. It addresses a wide variety of water management issues in buildings, ranging from the technical possibilities, hydraulic and financial efficiency, and public acceptance of decentralized water systems, to their impact on sewage systems. Climate changes, population growth, and progressive urbanization are the main causes of the growing interest in alternative sources of water around the world. Decentralized systems are seen not only as solutions that can effectively save water, but also as systems that can operate partially or completely independently of centralized suppliers. With these aspects in mind, the main focus of this book is on showcasing a new approach to water management at the building scale. The findings and insights presented here will support the development of future technical guidelines for using alternative water systems in urban areas - an aspect that is particularly important since, in many European countries, these systems are only very rarely used.

This book presents several complex case studies related to water management and planning in the context of pollution, growing demands, and global climate change in Mexico, but which are also relevant for other countries in Latin America. These concerns are of critical importance for policymakers who are coping with multiple conflicting interests. Water availability in Mexico is polarized, with abundant rainfall and large rivers in the south, and desert-like conditions in the north. The central region, which is the most industrialized, is overpopulated. Mexico City pours millions of cubic meters of "blackwater" into the northern valley daily and receives its clean water from the south. To address these unsustainable conditions, the world's 4th biggest water treatment plant went into operation in 2018. The water infrastructure and governance must satisfy the demands of all sectors, including agricultural, urban, and economic activities. At the same time, water resources are affected by drought, and climate change puts constraints on the supply. As such, regulation and monitoring are important when it comes to adherence to agreed plans and priorities. The book is divided into four sections. 1: Water Availability discusses quantitative aspects, such as supply, methods of calculation, and fracking. 2: Water Quality highlights pollution risks and diagnosis of water resources. 3: Water Allocation examines the sectoral demands and vulnerability due to unsustainable irrigation. 4: Water Governance and Management focuses on laws, urban rules, national parks, planning, and integrated water resources management, among other topics. The chapters include illustrative case studies in Mexico, such as basins, cities, reservoirs, and aquifers, water supply demand assessment, planning, and management.

This book focuses on interdisciplinary issues of human health in the changing urban environments of India's largest megacities-Delhi and Mumbai. The authors explore human health concerns related to increased temperatures and air pollution in these cities in a study based on primary data collected through interviews, as well as secondary data on causes of mortality from 2001 to 2012. During this period, the surface temperatures for both megacities were mapped using Landsat Images. The rapidly increasing populations of cities and urban centers alter ecosystem services such as water, air and land cover, with disastrous impacts on health and wellbeing, particularly in megacities. In 2015, polluted air was estimated to have been responsible for 6.4 million deaths worldwide, and it is projected that it will cause between 6 and 9 million deaths per year by 2060. In 2017, outdoor air pollution resulted in 1.2 million deaths in India and brought about a 3% loss in GDP. The increase in population, vehicles, and industries has led to changes in land use and land cover and a rise in city temperatures and air pollution, creating urban heat islands (UHIs). Together, UHIs and air pollution have damaging impacts on human health that range from stress and headache to asthma, bronchitis, and chronic diseases, and even to death. Delhi has been experiencing emergency conditions in terms of environmental health over the past two years. At the same time, both the Delhi and Mumbai urban agglomerations are growing at a rapid pace, and the United Nations has projected that they will be the second and third most populous cities in the world by 2025. In this context, the book offers significant insights into the past patterns and responses to the present global urban health emergencies, and explores sustainable means of combating the problem to enable college and university researchers to develop innovative solutions. Further. It presents trans-disciplinary research that cuts across the WHO Action Plan, the Sustainable Development Goals, the Sendai Framework for Disaster Risk Reduction, and Habitat III to help policymakers gain a better understanding of the global challenges of urban health and wellbeing. The book is especially useful for students and researchers in geography, urban demography, urban studies, environmental studies, health sciences, and policy studies.

The risks and consequences of environmental change are increasing, leading to massive losses in terms of ecosystems and having a huge impact on human populations. As such, global thinkers, environmentalists, scientists and policy makers are focusing on finding solutions and ways to sustain life on Earth. Anthropogenic impacts on the climate system can only be mitigated by the restoration of existing natural resources and the sustainable development of the environment and society. This book discusses the potential of green technology in waste management, wetland restoration, presenting the latest developments in the field of bioenergy, green ecology, bioremediation and microbial management. Wetlands are one of Earth's most important ecosystems, and they provide valuable services to human societies, such as minimizing the impacts of floods, acting as a carbon sink, and offering water purification as well as recreational opportunities. Wetlands may be natural or constructed, and the effectiveness of wetland services largely depends on the diversity of macrophytes affecting the algal production, plant biomass and nutrient status of the system. In addition, they are one of the richest microbial ecosystems on earth: the rhizosphere, soil and water interface enhances wetland services with implications ranging from phytoremediation to microbial bioprospection. However, in order to function properly, they need to be effectively redesigned, reengineered, protected and maintained. The book addresses the dynamic relation between three global concerns: environmental pollution, resource exploitation and sustainability. It describes the utilization of resources like wastes (municipal, industrial, agricultural, mine drainage, tannery, solid, and e waste), plants, algae and microbes for production of renewable biofuel, biofertilizers and other value added products to achieve the goal of sustainable development. The book also discusses the current and future trends in employing wetlands in improving water quality. In addition it presents the latest international research in the fields of wetland science, waste management, carbon sequestration and bioremediation. Highlighting a broad spectrum of topics and strategies for achieving a sustainable environment, the book offers researchers, students and academics insights into utilizing resources in a sustainable way.
