Snow and ice environments support significant biological activity, yet the biological importance of some of these habitats, such as glaciers, has only recently gained appreciation. Collectively, these ecosystems form a significant part of the cryosphere, most of which is situated at high latitudes. These ice environments are important sentinels of climate change since the polar regions are presently undergoing the highest rates of climate warming, resulting in very marked changes in the extent of ice caps, glaciers, and the sea ice. Glacial systems are also regarded as an analogue for astrobiology, particularly for Mars and the moons of Jupiter (e.g. Europa), and one of the justifications for research in this area is its potential value in astrobiology. This timely and accessible volume draws together the current knowledge on life in snow and ice environments. It describes these often complex and often productive ecosystems, their physical and chemical conditions, and the nature and activity of the organisms that have colonised them. The cryosphere is the domain of extremophiles, organisms able to adapt to the physiological and biochemical challenges of harsh cold conditions where liquid water may only be present for relatively short periods each year. The majority of extremophiles in ice and snow are microorganisms. The Ecology of Snow and Ice Environments is intended for the non-specialist, enabling environmental scientists to understand the biological functioning of extreme cold environments and for biologists to gain knowledge of the nature of the cryosphere.
Much has been written on security in Africa—its democratic deficit, poor civil-military relations, and myriad conflicts—but these are often treated in isolation from one another. This book takes a different approach, as it links all of these issues to the dynamics of the Anthropocene. Penned by African scholars on the continent and in the diaspora, it examines the different challenges not as separate entities but as outcomes of the Anthropocene Age. In this geological epoch, humans have become a global force—unfortunately, not necessarily for good. The interaction between humans and the climate, the effects of waste, the impact of pollution on marine and terrestrial ecosystems, the loss of biodiversity, and the change in the chemical composition of the soil, oceans and atmosphere are key identifiers of the age of the Anthropocene. This has fueled conflict and instability from the vast swathes of the Sahel to Somalia. Responding to these issues of insecurity without understanding their inter-connectedness and how this relates to the environment can only result in failure. From this perspective, the current structures in place are inadequate for the task of confronting insecurity at the state and continental levels, as represented by the African Union. What is needed is a radical reevaluation of Africa’s security architecture and approach to security. This necessitates pooling sovereignty on a continental and global level. It necessitates less state-centric responses that include civil society and the business community as equal partners of states in order to collectively confront insecurity in the age of the Anthropocene. • The authors are academics, policy makers and military veterans who have worked in building capacity on the African continent• The book is comprehensive in scope, strong on theory, pragmatic in policy and reflects experience from the field.• The authors approach makes the book easy, interesting and intriguing.
This coloring and activity book for children explores the historic Nez Perce National Historic Trail which winds through Oregon, Idaho, Montana, and Wyoming. The Nez Perce, or Nimiipoo, are the native people who lived in an area of the interior Northwest stretching from the Bitterroot Mountains in the east, to the Blue Mountains in the west. Using matching games, puzzles, and other activities, Along the Nez Perce Trail introduces young people to the natural world through the language and concepts of the Nimiipoo.
This book critically engages with how the conservation of tropical coral reefs is financed. Beginning with the context of tropical coral reef degradation and loss, alongside an overview of tropical ecology, global environmental policy and finance, the book reviews several conservation financing instruments. These include ecotourism, debt-for-nature swaps, impact investments, and government domestic budgetary expenditures. From the Great Barrier Reef, to the Coral Triangle, to the Mesoamerican Reef, tropical coral reef degradation and loss are serious global environmental issues, contributing to loss revenue and food insecurity for coastal communities, and species extinction. Yet, many leading companies, individuals, and governments are making a positive impact on tropical coral reef conservation through the use of conservation finance. Conservation of Tropical Coral Reefs, using 30 case studies which span 23 countries and 6 continents, tells the history of international conservation finance and provides a variety of options for individuals, businesses, and governments to support conservation financing projects.
This book is an ambitious integration of ecological, archaeological, anthropological land use sciences, drawing on human geography, demography and economics of development across the East Africa region. It focuses on understanding and unpicking the interactions that have taken place between the natural and unnatural history of the East African region and trace this interaction from the evolutionary foundations of our species (c. 200,000 years ago), through the outwards and inwards human migrations, often associated with the adoption of subsistence strategies, new technologies and the arrival of new crops. The book will explore the impact of technological developments such as transitions to tool making, metallurgy, and the arrival of crops also involved an international dimension and waves of human migrations in and out of East Africa. Time will be presented with a widening focus that will frame the contemporary with a particular focus on the Anthropocene (last 500 years) to the present day. Many of the current challenges have their foundations in precolonial and colonial history and as such there will be a focus on how these have evolved and the impact on environmental and human landscapes. Moving into the Anthropocene era, there was increasing exposure to the International drivers of change, such as those associated with Ivory and slave trade. These international trade routes were tied into the ensuing decimation of elephant populations through to the exploitation of natural mineral resources have been sought after through to the present day. The book will provide a balanced perspective on the region, the people, and how the natural and unnatural histories have combined to create a dynamic region. These historical perspectives will be galvanized to outline the future changes and the challenges they will bring around such issues as sustainable development, space for wildlife and people, and the position of East Africa within a globalized world and how this is potentially going to evolve over the coming decades.
Students taking undergraduate degrees in geography, ecology, earth science, and environmental science frequently take an introductory unit in Physical Geography. Some will have not done any geography since their early teens, while others have more recent knowledge. This range of backgrounds can be challenging for both the instructor and the student, this primer aims to help. A primer is a readable introduction to a subject, more technical than a piece of popular science, but less detailed than a specialist textbook. It aims to give the reader a platform in a subject with which they may be unfamiliar, so that they can proceed simultaneously, or sequentially, to more advanced texts and information. Ideally the primer should have something for those without any knowledge, while also challenge and entertaining those who do. Not quite bedtime reading, but a step in that direction. Our Dynamic Earth introduces students to the Earth's origins, to plate tectonics, atmospheric and oceanographic circulation, as well as to a range of Earth surface processes. Idea to get you started in your studies.
Biogeoscience is a rapidly growing interdisciplinary field that aims to bring together biological and geophysical processes. This book builds an enhanced understanding of ecosystems by focusing on the integrative connections between ecological processes and the geosphere, hydrosphere and atmosphere. Each chapter provides studies by researchers who have contributed to the biogeoscience synthesis, presenting the latest research on the relationships between ecological processes, such as conservation laws and heat and transport processes, and geophysical processes, such as hillslope, fluvial and aeolian geomorphology, and hydrology. Highlighting the value of biogeoscience as an approach to understand ecosystems, this is an ideal resource for researchers and students in both ecology and the physical sciences.
Describing sacred waters and their associated traditions in over thirty countries and across multiple time periods, this book identifies patterns in panhuman hydrolatry. Supplying life's most basic daily need, freshwater sources were likely the earliest sacred sites, and the first protected and contested resource. Guarded by taboos, rites and supermundane forces, freshwater sources have also been considered thresholds to otherworlds. Often associated also with venerated stones, trees and healing flora, sacred water sources are sites of biocultural diversity. Addressing themes that will shape future water research, this volume examines cultural perceptions of water's sacrality that can be employed to foster resilient human-environmental relationships in the growing water crises of the twenty-first century. The work combines perspectives from anthropology, archaeology, classics, folklore, geography, geology, history, literature and religious studies.
This volume investigates crucial ways in which nature has been apprehended, understood and valued in different cultures and over time. It is grounded in current global concerns about growing threats to the natural environment. Through a critical appraisal of specific examples, it ranges widely over historical and contemporary attitudes and behaviours. It presents a wide ranging analysis of selected ideas and attitudes in the evolution mainly of western civilisation, from the time of the cave artists to the present day. It argues for preservation and conservation of the natural resources and beauty of the earth in the face of religious supernatural arguments and the rise of consumer capitalism and consumerism.
The study of volcano-ice interactions, or 'glaciovolcanism', is a field experiencing exponential growth. This comprehensive volume presents a discussion of the distinctive processes and characteristics of glaciovolcanic eruptions, their products, and landforms, with reference to both terrestrial and Mars occurrences. Supported by abundant diagrams and photos from the authors' extensive collections, this book outlines where eruptions have occurred and will occur in the future on Earth, the resulting hazards that are unique to volcano-ice interactions, and how the deposits are used to unravel planetary palaeoclimatic histories. It has a practical focus on lithofacies, glaciovolcanic edifice morphometry and construction, and applications to palaeoenvironmental studies. Providing the first global summary of past and current work, this book also identifies those areas in need of further research, making this an ideal reference for academic researchers and postgraduate students, in the fields of volcanology, glaciology, planetary science and palaeoenvironmental studies.
The concentration of private power over media has been the subject of intense public debate around the world. Critics have long feared waves of mergers creating a handful of large media firms that would hold sway over public opinion and endanger democracy and innovation. But others believe with equal fervor that the Internet and deregulation have opened the media landscape significantly. How concentrated has the American information sector really become? What are the facts about American media ownership? In this contentious environment, Eli Noam provides a comprehensive and balanced survey of media concentration with a methodical, scientific approach. He assembles a wealth of data from the last 25 years about mass media such as radio, television, film, music, and print publishing, as well as the Internet, telecommunications, and media-related information technology. After examining 100 separate media and network industries in detail, Noam provides a powerful summary and analysis of concentration trends across industries and major media sectors. He also looks at local media power, vertical concentration, and the changing nature of media ownership through financial institutions and private equity. The results reveal a reality much more complex than the one painted by advocates on either side of the debate. They show a dynamic system that fluctuates around long-term concentration trends driven by changing economics and technology. Media Ownership and Concentration in America will be essential reading and a trove of information for scholars and students in media, telecommunications, IT, economics, and the history of business, as well as media industry professionals, business researchers, and policy makers around the world. Critics and defenders of media trends alike will find much that confirms and refutes their world view. But the next round of their debate will be shaped by the facts presented in this book.
This volume explores the climates, landscapes, ecosystems and hazards that comprise the Mediterranean world. It traces the development of the Mediterranean landscape over very long timescales and examines modern processes and key environmental issues in a wide range of settings. The Mediterranean is the only region on Earth where three continents meet and this interaction has produced a very distinctive Physical Geography. This book examines the landscapes and processes at the margins of these continents and the distinctive marine environment between them. Catastrophic earthquakes, explosive volcanic eruptions and devastating storms and floods are intimately bound up within the history and mythology of the Mediterranean world. This is a key region for the study of natural hazards because it offers unrivalled access to long records of hazard occurrence and impact through documentary, archaeological and geological archives. The Mediterranean is also a biodiversity hotspot; it has been a meeting place for plants, animals and humans from three continents throughout much of its history. The Quaternary records of these interactions are more varied and better preserved than in any other part of the world. These records have provided important new insights into the tempo of climate, landscape and ecosystem change in the Mediterranean region and beyond. The region is unique because of the very early and widespread impact of humans in landscape and ecosystem change - and the richness of the archaeological and geological archives that chronicle this impact. This book examines this history and these interactions and places current environmental issues in long term context.

Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.
This book provides a detailed treatment of the ecological, economic and social impacts in the context of environmental impact assessment (EIA) and makes clear the necessary link between EIA and the sustainability principles of protecting biodiversity, risk aversion, and inter and intra-generational equity. It proposes that the benefits and costs of a project need to be weighted according to who bears them, giving particular attention to the planet's poor. Furthermore, this book presents a comprehensive analysis of environmental offsetting which has come to be commonly resorted to when negative impacts cannot be mitigated. In this context, the book argues that offsetting is only viable if advanced offsets are quarantined through a Strategic Environmental Impact approach. Finally, the book explores the role of the various disciplines which need to be mastered in undertaking an EIA. This book takes you on a journey from the beginning of environmental impact assessment to the present day. It is a scholarly warts and all study. For each trial and tribulation, Hundloe presents a remedy. It is essential reading and an invaluable reference for environmental practitioners, politicians, policy makers, academics and, the most important group, future environmental practitioners.
This volume reviews recent hydrological and environmental issues resulting from human-induced water pollution practices while providing case studies on the physical, chemical, and eco-biological techniques used to mitigate the impacts of river ecosystem pollution in South Asian countries. The book demonstrates the key methods of measurement, monitoring, mapping, and modeling of river water quality and how it is impacted by pollution and incorporates contemporary geospatial technological applications for the management and sustainability of future water resources. The major topics that the book addresses are the fundamental concepts of river ecosystem health, riverine ecology and habitats, risk assessment of riverine pollution, and technology-based river pollution control strategies. The book will serve as an interdisciplinary guide for researchers, students, and GIS specialists working in various disciplines, including pollution hazards, river ecosystem restoration, water quality, remote sensing, zoology, natural resources management, and environmental geography.
This book focuses on the application of geospatial technologies to study the land use land cover (LULC) dynamics, agricultural water management, water resources assessment and modeling, and studies on natural disasters. LULC dynamics is one of the major research themes for studying global environmental change using remote sensing data. The section on LULC dynamics covers the multi-variate criteria for land use and land cover classification and change assessment in the mountainous regions. Further, LULC change detection of the Tons river basin and LULC dynamics at decadal frequency are studied to derive adaptation and mitigation strategies. Landscape-level forest disturbance modeling, together with conservation implications, is also included. The watershed management approach is necessary for comprehensive management of land and water resources of any region, where studies on multi-criteria analysis for rainwater harvesting planning and its impact on land use land cover transformations in rain-fed areas using geospatial technologies are presented in this book. The book will be useful for academics, water practitioners, scientists, water managers, environmentalists, and administrators, NGOs, researchers, and students who are actively involved in the application of geospatial technologies in LULC studies, agricultural water management and hydrological modelling and natural disasters for addressing the challenges being posed by climate change while addressing issues of food and water securities
The purpose of this book is to demonstrate that the land-based geomorphological evidence of environmental change from late Pleistocene, Holocene, historical and contemporary time periods remain central to a full understanding of global environmental change both at the global and regional scale. Geomorphology, Human Activity and Global Environmental Change begins with a look at how global Pleistocene climate change affected placation and tectonic instability. The middle section then looks at environments unaffected by human activity in an attempt to explore scenarios that may result from climate change alone in the future. The final two sections look at human activity and global environmental change by monitoring floodplain stratigraphy, cartographic evidence, sediment transport, watershed studies and coastal surveys, and offer practical advice on land management issues. Case studies from Europe, North America and Asia are used. This book is intended for environmental consultants, civil engineers, postgraduates and researchers in geomorphology, geology, civil engineering, environmental science and geography and as supplementary reading for upper level undergraduates of geomorphology in departments of geography, geology and environmental science.
This is the first book to describe the ecology of high latitude
lakes, rivers and glacial environments in both the North and South
polar regions. From the lake-rich floodplains of the Arctic to the
deep, enigmatic waters of Lake Vostok, Antarctica, these regions
contain some of the most extraordinary aquatic ecosystems on Earth.
They provide a fascinating diversity of habitats for plant, animal
and microbial communities, and are proving to be valuable model
systems for exploring many ecological themes including
landscape-lake interactions, adaptation of life to environmental
extremes, and controls on the structure and functioning of aquatic
ecosystems. Some of these waters also have direct global
implications, including permafrost thaw lakes as sources of
greenhouse gases, subglacial aquatic environments as a storehouse
of ancient microbes, and Arctic rivers as major inputs of
freshwater and organic carbon to the World Ocean. Given that many
polar areas are experiencing greater climate warming than at lower
latitudes, these ecosystems can also be viewed as sentinels of
global change.
As the risks of the climate crisis continue to grow, so too do the challenges of facing a harsh climate future with honesty and courage; justice and compassion; meaning and purpose. Hope and Courage in the Climate Crisis explores diverse sources of learning and wisdom -from climate scientists and activists; philosophers and social theorists; Indigenous cultures and ways of life; faith based and spiritual traditions; artists and writers -which can help us live courageous, compassionate and creative lives in a world of rapidly accelerating climatic and ecological risk. Accelerating the transition to a just and resilient zero-carbon society will require visionary leadership and courageous collective action. Awareness that rapid action might still be insufficient to prevent severe and irreversible social and ecological damage is however a source of deep concern for many people passionately committed to decisive climate action. Drawing on broad experience as a climate activist, researcher and policy maker John Wiseman provides a wide ranging, accessible and provocative guided tour of ideas which can inspire and sustain radical hope and defiant courage in the long emergency which now lies before us.
This detailed exposition gives background and context to how modern biogeography has got to where it is now. For biogeographers and other researchers interested in biodiversity and the evolution of life on islands, Biogeology: Evolution in a Changing Landscape provides an overview of a large swathe of the globe encompassing Wallacea and the western Pacific. The book contains the full text of the original article explored in each chapter, presented as it appeared on publication. Key features: Holistic treatment, collecting together a series of important biogeographical papers into a single volume Authored by an expert who has spent nearly three decades actively involved in biogeography Describes and interprets a region of exceptional biodiversity and extreme endemism The only book to provide an integrated treatment of Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic Islands and Antarctica Offers a critique of fashionable neo-dispersalist arguments, showing how these still suffer from the same weaknesses of the original Darwinian formulation. The chapters also include analysis of many major theoretical and philosophical issues of modern biogeographic theory, so that those interested in a more philosophical approach will find the book stimulating and thought-provoking.
This book provides a critical study of environmental regulation and its enforcement in New Zealand, situated within green criminology. It seeks to address the question of whether the offences in the Resource Management Act 1991 are 'working', by drawing on a range of sources including: central government data, local government policies and reports on enforcement, information requests of councils, studies of local authority enforcement behaviour and case law to. Through highly layered and richly textured analysis, the project exposes the problems that can arise when an expansive approach is taken to offences, penalties and institutional arrangements in an environmental regulatory statute. It emphasizes how discussions of harm and what should be unlawful will ensure that law-makers' enforcement tools will align with their goals for punishment. It examines higher-level issues such as 'wrongfulness' and 'criminality' in the environmental regulatory context and explores the relevance of its findings to jurisdictions outside of New Zealand. It also discusses the pros and cons of criminalisation and punishment versus restoration. It speaks to those interested in green criminology, regulatory compliance and enforcement, and applications of criminal law.
This book introduces systematically the cryospheric science, covering the formation, development, evolution, and research methods of each component of the cryosphere, the interaction between the cryosphere and the other spheres of the climate system and the anthroposphere, and the hot topics of social and economic sustainable development and geopolitics. The authors are world-renowned experts and scientists working in the related fields. They have a deep understanding and accurate grasp of the basic theory, evolution mechanism, and international frontiers of the cryosphere, as well as rich teaching experience, which makes this book suitable also as textbook for graduate students. It is also the first book that introduces the knowledge of cryospheric science systematically. In addition to theoretical knowledge, the book also introduces field work and experimental analysis. It should be of interests for the scholars and graduate student working in the fields of geography, hydrology, geology, geomorphology, atmosphere, ecology, environment, oceanography, and regional economic and social sustainable development.
This book discusses how Coal Bed Methane (CBM) could help the acceleration of the energy transition in a 'just' way in Indonesia, due to the country's potential CBM reserves (and current dependence on climate damaging coal). Developing countries face multiple challenges in achieving their energy transitions. CBM in Indonesia could potentially be a catalyst for energy transition and subsequently improve access to energy. However, CBM faces numerous challenges and although Indonesia first developed its domestic CBM sector over more than a decade ago, they are still to implement this successfully. This book exposes the challenges and opportunities of CBM, exploring what lessons other countries could learn from Indonesia to improve the industry with a view to achieving energy transition and climate change targets. This book will be an invaluable reference for researchers and practitioners working in this field.
This book discusses the conditions that underpin configuration of specific places as resource peripheries and the consequences that such a socio-spatial formation involves for those places. The book thereby provides an interdisciplinary approach underpinned by economic geography, political ecology, resource geography, development studies and political geography. It also discusses the different technological, political and economic changes that make the ongoing production of resource peripheries a distinctive socio-spatial formation under the global economy. Through a global and interdisciplinary perspective that uncovers ongoing political processes, socio-economic changes and socio-ecological dynamics at resource peripheries, this book argues that it is critical to take a more profound appraisal about the socio-spatial processes behind the contemporary way in which capitalism is appropriating and transforming nature.
The Physical Geography of South America presents an enduring statement of the continent's fascinating environments. Written by international specialists, it addresses themes ranging from tectonism and climate change to biotoc endemism; analyzes specific regions from the Amazon forests to the Patagonian steppes; and evaluates human impacts on the environment over time. |
