This book provides an analysis of the ecological conditions and ecosystem goods and services of the Zambezi River Basin (ZRB), the fourth largest river in Africa. Various environmental and anthropogenic factors; inclusive of climate, environmental flows, hydrology, morphology, pollution and land use changes among others and their interactions are considered as drivers of the river ecosystems. The impacts of these drivers on aquatic biota, river ecological integrity, and the livelihoods of surrounding communities are analysed within the socio-economic-policy context. The book goes beyond the usual inventories and basic research by using the comparative research method (CRM) in a trans-disciplinary manner. This CRM analytical approach in this book seeks to interrogate the differences or similarities in socio-economic systems, livelihoods, ecological systems, ecosystem goods and services, their usage and management under the seemingly different cultural, socio-economic conditions expected across boarders that are within the ZRB. The multidisciplinary approach also connects the typical ecological research with social dimensions in a holistic manner. The book therefore, provides empirical and research based evidence to support strategic planning and policy development in the wake of ecological changes that nations and indeed regions such as the ZRB are grappling with while seeking to sustainably manage precious river systems.

This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.

Pollution has been a developing problem for quite some time in the modern world, and it is no secret how these chemicals negatively affect the environment. With these contaminants penetrating the earth’s water supply, affecting weather patterns, and threatening human health, it is critical to study the interaction between commercially produced chemicals and the overall ecosystem. Understanding the nature of these pollutants, the extent in which they are harmful to humans, and quantifying the total risks are a necessity in protecting the future of our world. The Handbook of Research on Emerging Developments and Environmental Impacts of Ecological Chemistry is an essential reference source that discusses the process of chemical contributions and their behavior within the environment. Featuring research on topics such as organic pollution, biochemical technology, and food quality assurance, this book is ideally designed for environmental professionals, researchers, scientists, graduate students, academicians, and policymakers seeking coverage on the main concerns, approaches, and solutions of ecological chemistry in the environment.

A common perception of global resource scarcity holds that it is inevitably a catalyst for conflict among nations; yet, paradoxically, incidents of such scarcity underlie some of the most important examples of international cooperation. This volume examines the wider potential for the experience of scarcity to promote cooperation in international relations and diplomacy beyond the traditional bounds of the interests of competitive nation states. The interdisciplinary background of the book’s contributors shifts the focus of the analysis beyond narrow theoretical treatments of international relations and resource diplomacy to broader examinations of the practicalities of cooperation in the context of competition and scarcity. Combining the insights of a range of social scientists with those of experts in the natural and bio-sciences—many of whom work as ‘resource practitioners’ outside the context of universities—the book works through the tensions between ‘thinking/theory’ and ‘doing/practice’, which so often plague the process of social change. These encounters with scarcity draw attention away from the myopic focus on market forces and allocation, and encourage us to recognise more fully the social nature of the tensions and opportunities that are associated with our shared dependence on resources that are not readily accessible to all. The book brings together experts on theorising scarcity and those on the scarcity of specific resources. It begins with a theoretical reframing of both the contested concept of scarcity and the underlying dynamics of resource diplomacy. The authors then outline the current tensions around resource scarcity or degradation and examine existing progress towards cooperative international management of resources. These include food and water scarcity, mineral exploration and exploitation of the oceans. Overall, the contributors propose a more hopeful and positive engagement among the world’s nations as they pursue the economic and social benefits derived from natural resources, while maintaining the ecological processes on which they depend.

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.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Scientists have long sought to unravel the fundamental mysteries of the land, life, water, and air that surround us. But as the consequences of humanity's impact on the planet become increasingly evident, governments are realizing the critical importance of understanding these environmental systemsâ€"and investing billions of dollars in research to do so. To identify high-priority environmental science projects, Grand Challenges in Environmental Sciences explores the most important areas of research for the next generation. The book's goal is not to list the world's biggest environmental problems. Rather it is to determine areas of opportunity thatâ€"with a concerted investmentâ€"could yield significant new findings. Nominations for environmental science's "grand" challenges were solicited from thousands of scientists worldwide. Based on their responses, eight major areas of focus were identifiedâ€"areas that offer the potential for a major scientific breakthrough of practical importance to humankind, and that are feasible if given major new funding. The book further pinpoints four areas for immediate action and investment.
