Environmental Effects of Afforestation in North-Western Europe - From Field Observations to Decision Support (Hardcover):... Environmental Effects of Afforestation in North-Western Europe - From Field Observations to Decision Support (Hardcover)
Gerrit W. Heil, Bart Muys, Karin Hansen
R4,269 Discovery Miles 42 690 Ships in 10 - 15 working days

Afforestation of former arable land is currently a common change in land use in many European countries. In addition to wood production, the new forests will provide a variety of environmental services, such as carbon sequestration or improved water quality. At the same time there may be negative impacts, such as reduced groundwater recharge. The contents of the book aims at developed techniques to estimate the environmental impacts, and guidelines and decision support systems (DSS) to enable national and international policy makers, but also forest managers, to maximize the benefits and minimize the adverse effects of afforestation. This book will describe afforestation research and shows the application of the developed decision support system.

Ecosystem-Based Disaster and Climate Resilience - Integration of Blue-Green Infrastructure in Sustainable Development... Ecosystem-Based Disaster and Climate Resilience - Integration of Blue-Green Infrastructure in Sustainable Development (Hardcover, 1st ed. 2021)
Mahua Mukherjee, Rajib Shaw
R4,295 Discovery Miles 42 950 Ships in 12 - 17 working days

This book provides an introduction to the critical role of ecosystem-based disaster risk resilience (Eco-DRR) for building community resilience to multiple environmental risks such as rising heat, water stress, and pollution. Blue-green infrastructure (BGI) is an Eco-DRR tool that is an under-explored paradigm and can respond as one common strategy to targets set by the Sustainable Development Goals (UNDP), Climate Agreements (UNEP), the Sendai Framework (UNISDR), and the New Urban Agenda (UNCHS). Highlighted here in a systematic way is the importance of blue-green infrastructures in resilience building. The purpose is to introduce readers to the challenging context of development and opportunity creation for Eco-DRR. The roles of policy, scientific research, and implementation are presented cohesively. An attractive proposition of the book is a collection of case studies from different parts of the world where integration of BGI is experimented with at various levels of success. It envisages that shared tacit experiences from the realm of practice will further strengthen explicit knowledge. The focus in this book is on need and context building, policy and science (investigation, analysis, and design), case studies, and a road map for the future in four successive parts. Each part is self-sufficient yet linked to its predecessor, successor, or both, as the case may be.

R5,490 Discovery Miles 54 900 Ships in 10 - 15 working days

Mediterranean islands exhibit many similarities in their biotic ecological, physical and environmental characteristics. There are also many differences in terms of their human colonization and current anthropogenic pressures. This book addresses in three sections these characteristics and examines the major environmental changes that the islands experienced during the Quaternary period. The first section provides details on natural and cultural factors which have shaped island landscapes. It describes the environmental and cultural changes of the Holocene and their effects on biota, as well as on the current human pressures that are now threats to the sustainability of the island communities. The second section focuses on the landscapes of the largest islands namely Sicily, Sardinia, Corsica, Cyprus, Crete, Malta and the Balearics. Each island chapter includes a special topic reflecting a particular characteristic of the island. Part three presents strategies for action towards sustainability in Mediterranean islands and concludes with a comparison between the largest islands. Despite several published books on Mediterranean ecosystems/landscapes there is no existing book dealing with Mediterranean islands in a collective manner. Students, researchers and university lecturers in environmental science, geography, biology and ecology will find this work invaluable as a cross-disciplinary text while planners and politicians will welcome the succinct summaries as background material to planning decisions.

Degrees Of Freedom: Living In Dynamic Boundaries (Hardcover): Alan D.M. Rayner Degrees Of Freedom: Living In Dynamic Boundaries (Hardcover)
Alan D.M. Rayner
R1,814 Discovery Miles 18 140 Ships in 12 - 17 working days

Drawing especially on insights emerging from studies of the cellular networks formed by fungi, this book describes the fundamental indeterminacy that enables life forms to thrive in and create inconstant circumstances. It explains how indeterminacy arises from counteraction between associative and dissociative processes at the reactive interfaces between living systems and their surroundings. It stresses the relevance of these processes to understanding the dynamic contexts within which living systems of all kinds - including human societies-explore for, use up, conserve and recycle sources of energy.By focusing on dynamic boundaries, the book counterbalances the discretist view that living systems are assembled entirely from building-block-like units - individuals and genes - that can be freely sifted, as opposed to channeled, by natural selection. It also shows how the versatility that enables life forms to proliferate in rich environments, whilst minimizing losses in restrictive environments, depends on capacities for error and co-operation within a fluid, non-hierarchical power structure. Understanding this point yields a more compassionate, less competitive and less self-centred outlook on life's successes and failures.

The second volume of "Adaptation and Evolution in Marine Environments - The Impacts of Global Change on Biodiversity" from the series "From Pole to Pole" integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present ) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

R8,153 Discovery Miles 81 530 Ships in 12 - 17 working days

Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITOEK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITOE K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.

R1,604 Discovery Miles 16 040 Ships in 12 - 17 working days

Ecological assessments are a critical component of land management planning and regulatory decision-making. In the United States, for example, the National Environmental Policy Act of 1969 directs that the environmental consequences associated with proposed management of federal lands be fully disclosed to the general public through environmental impact assessments. In a similar manner, over 40 other countries have legislated the use of some type of ecological assessment as a prerequisite for effective environmental planning and land management. Although ecological assessments can be conducted at a variety of spatial scales and may address one or many issues, the main intent of this book is to describe topics with particular importance to strategic integrated ecological assessments at a regional or subregional scale. The chapters in this book range from overviews of basic ecological principles, to suggestions concerning ecosystem characterization and analysis, to systematic reviews of selected case studies. In this respect, the book provides both theoretical and practical advice for future ecological assessments given specific land use planning objectives. This book will be the reference standard for any person engaged in any ecological assessment exercise at any level, whether they work for national, state or regional authorities or in academia.

Mir S. Mulla joined the faculty of the Entomology Department at the University of California, Riverside in 1956, only two years after the Riverside campus was established as an independent campus within the University of California system. Prior to his appointment, Mir received his B.S. from Cornell University and then moved to the University of California, Berkeley to pursue his graduate studies. His Ph.D. from Berkeley, awarded in 1955, completed his formal American education which was the purpose of his immigration from his native Kandahar in Afghanistan. In his over 50 years at Riverside, Mir has made an incalculable impact on vector biology both within the United States and in developing countries throughout the world. Within Southern California, Mir's basic and applied research led to the rapid and sustainable control of mosquitoes and eye gnats in the Coachella Valley and so directly enabled this region to grow to the thriving, large community it is today. In 2006 his efforts in facilitating the development of the low desert of southern California were recognized through the dedication of the Mir S. Mulla Biological Control Facility by the Coachella Valley Mosquito and Vector Control District. His success has been so profound that it remains somewhat cryptic to the many who now reside in, visit, and enjoy, this region of California, oblivious to the insect problems that severely restrained development until Mir and his students ?rst applied their expertise many decades ago.

R5,574 Discovery Miles 55 740 Ships in 10 - 15 working days

The Ecological Bases for Lake and Reservoir Management provides a state-of-the-art review of the range of ecologically-based techniques necessary for the holistic management of lakes and their catchments. Most of the methods, case studies and national policies reviewed are directed towards management of the largest problem - eutrophication - with the emphasis on the multiple-scale approach needed for successful management and restoration. Case studies come from the USA and ten European countries, and range from single lakes through to lake districts and national inventories. Several essays precede the practical chapters with thought-provoking comments on the political, social and economic climate of water management.

R2,789 Discovery Miles 27 890 Ships in 10 - 15 working days

This book focuses on the emerging health issues due to climate change, particularly emphasizing the situation in developing countries. Thanks to recent development in the areas of remote sensing, GIS technology, and downscale modeling of climate, it has now become possible to depict and predict the relationship between environmental factors and health-related event data with a meaningful spatial and temporal scale. The chapters address new aspects of environment-health relationship relevant to this smaller scale analyses, including how considering people's mobility changes the exposure profile to certain environmental factors, how considering behavioral characteristics is important in predicting diarrhea risks after urban flood, and how small-scale land use patterns will affect the risk of infection by certain parasites, and subtle topography of the land profile. Through the combination of reviews and case studies, the reader would be able to learn how the issues of health and climate/social changes can be addressed using available technology and datasets. The post-2015 UN agenda has just put forward, and tremendous efforts have been started to develop and establish appropriate indicators to achieve the SDG goals. This book will also serve as a useful guide for creating such an indicator associated with health and planning, in line with the Ecohealth concept, the major tone of this book. With the increasing and pressing needs for adaptation to climate change, as well as societal change, this would be a very timely publication in this trans-disciplinary field.

P. M. Malanotte-Rizzoli, Valery N. Eremeev
R3,098 Discovery Miles 30 980 Ships in 12 - 17 working days

This book is the outcome of a NATO Advanced Research Workshop on "The Eastern Mediterranean as a laboratory basin for the assessment of contrasting ecosystems" that was held in Kiev, Ukraine, March 23-27, 1998. The scientific rationale of the workshop can be summarized as follows. The Eastern Mediterranean is the most nutrient impoverished and oligotrophic large water body known. There is a well-defined eastward trend in nutrient ratios over the entire Mediterranean that starts at the Gibraltar Straits and, through the western basin, proceeds to the Ionian and Levantine Seas. Supply of nutrients to the entire Mediterranean is limited by inputs from the North Atlantic and various river systems along the sea. The unique feature of the Mediterranean is the presence of an eastward longitudinal trend in available nitrate/phosphate ratios. This apparently induces a west-to-east variation in the structure of the pelagic food web and trophic interactions. In this context the Mediterranean, and in particular its Eastern basin, provides probably a unique platform to explore the hypotheses related to the suggested phosphate-limitation on production and to the shift between "microbial" and "classical" modes of operation of the photic food web. The major exception of the overall oligotrophic nature of the Eastern Mediterranean is the highly eutrophic system of the Northern Adriatic Sea. Here, during the last two decades the discharges of the northern rivers (especially of the Po), together with municipal sewage, have led to a very marked increase of nutrients and subsequent imponent eutrophication events.

The book is composed of eight chapters, each of which are organised as walks around the Tewkesbury (UK) countryside, which move from the specific to increasingly broader ideas. So, the MS starts with an individual's relationship to their environment (Avon and Severn Valleys Loop) that leads to a description of conservation issues at local, national and international levels, and ultimately to a discussion of the importance of Citizen Science (Coombe Hill - Apperley -Deerhurst). The following chapter (Mythe Bridge - Forthampton - Tewkesbury) looks at science as it is actually practiced and its role in modern society by an analysis of the theory of Continental Drift and a biography of Alfred Wegener. This is a story that really deserves a much wider audience, as the idea was, in my opinion, as revolutionary as general relativity or quantum mechanics, and Wegener himself was such a heroic character. The following chapter (Tewkesbury Ham) also uses biography - this time of Alfred Russel Wallace - to investigate his ideas about how animal and plant distributions are inextricably linked to geological change. Wallace was every bit as heroic as Wegener, lived an even more adventurous life, and also deserves to be more widely known and appreciated. 2013 is the centenary of his death and he will be much in the news this year, so it would be timely to publish an account of his life and work suitable for the general public. The chapters on Wegener and Wallace set the scene for a detailed discussion of biogeography. This has been an active area of research for the past 30 years and I think it's about time that somebody wrote about what has been an intellectually exciting and profoundly significant development in our view of ourselves and the world we live in.

The proceedings of the joint BMB 15 and ECSA 27 Symposium provides the reader with some of the advances in the study of biology, ecology, and physical and biochemical modelling of enclosed or semi-enclosed marine, brackish and estuarine systems (the Baltic Sea, the North Sea, the White Sea, the Black Sea, and the Ionian Sea). The book covers a wide range of topics in this field, including hydrography and modelling, eutrophication, environmental gradients, pelagic and benthic communities, introduced species and case studies of environmental impact. This volume of 28 papers summarizes current knowledge on the broad-scale topics of enclosed and semi-enclosed marine systems, and should be of interest to scientists, students and administrators within the field of marine ecology, environmental impact control and conservation.

Wild by Design - The Rise of Ecological Restoration (Hardcover): Laura J. Martin Wild by Design - The Rise of Ecological Restoration (Hardcover)
Laura J. Martin
R866 Discovery Miles 8 660 Ships in 12 - 17 working days

An environmental historian delves into the history, science, and philosophy of a paradoxical pursuit: the century-old quest to design natural places and create wild species. Environmental restoration is a global pursuit and a major political concern. Governments, nonprofits, private corporations, and other institutions spend billions of dollars each year to remove invasive species, build wetlands, and reintroduce species driven from their habitats. But restoration has not always been so intensively practiced. It began as the pastime of a few wildflower enthusiasts and the first practitioners of the new scientific discipline of ecology. Restoration has been a touchstone of US environmentalism since the beginning of the twentieth century. Diverging from popular ideas about preservation, which romanticized nature as an Eden to be left untouched by human hands, and conservation, the managed use of natural resources, restoration emerged as a "third way." Restorationists grappled with the deepest puzzles of human care for life on earth: How to intervene in nature for nature's own sake? What are the natural baselines that humans should aim to restore? Is it possible to design nature without destroying wildness? Laura J. Martin shows how, over time, amateur and professional ecologists, interest groups, and government agencies coalesced around a mode of environmental management that sought to respect the world-making, and even the decision-making, of other species. At the same time, restoration science reshaped material environments in ways that powerfully influenced what we understand the wild to be. In Wild by Design, restoration's past provides vital knowledge for climate change policy. But Martin also offers something more-a meditation on what it means to be wild and a call for ecological restoration that is socially just.

It is not possible to understand the apparent stability of the Earth's climate and environment unless we can fully understand how the best possible environmental conditions may be maintained for life to exist. Human colonization of areas with natural biota, for industrial or agricultural activities, will lead to degradation of those natural communities and violation of the BRE (biotic regulation of the environment) principle. Thus to maintain an environment on Earth that is suitable for life it is necessary to preserve and allow the natural recovery of natural biotic communities, both in the oceans and on land. This book is devoted to a quantitative version of the BRE concept, and is built on a foundation of modern scientific knowledge accumulated in the fields of physics and biology.

R2,794 Discovery Miles 27 940 Ships in 10 - 15 working days

Addressing the links between science and the real world with a sound scientific baseline, "Coastal Water Bodies" targets researchers of various disciplines whose interest lies in the integrated sustainable management of coastal water bodies. The main topic of this book is not the ecology according to its accepted meaning, but rather the places and people concerned the coastal zones of the Mediterranean that are rich in ecological value and the local people who survive thanks to these environmental resources.

Integration is the joint consideration of different aspects of water uses and values, and new ways of understanding and managing conflicts around water use are needed if people are to benefit from integration. Sustainability of the ecological and socioeconomic environments requires a climate in which conflicts, if they need to exist, are properly managed in a non-destructive manner.

Charles Cockell, Andrew R. Blaustein
R2,802 Discovery Miles 28 020 Ships in 10 - 15 working days

This book discusses UV radiation, its effects on ecosystems and the likely evolutionary consequences of changed UV radiation environments, past, present and future. The first two chapters examine the history of the UV radiation climate of earth and the factors that determine organismal and ecosystem exposure. Their purpose is to give the reader a physical perspective on UV radiation and an understanding of the constantly changing UV environment that ecosystems are exposed to over time. Variations in the UV radiation environment occur at the local level (such as boundary layer and plant canopy effects) through to global-scale changes (such as alterations in the column abundance of UV-B protecting ozone). UV radiation regimes also vary over temporal scales. These alterations occur on time scales of seconds (the movement of clouds and plant canopies) to literally billions of years (gross long-term changes in the composition of the Earth's atmosphere). In the chapters that follow five specific biological and ecological topics in photobiology are considered. They are effects of UV radiation on amphibians, plants, corals, aquatic microbial ecosystems and Antarctic ecosystems that are exposed to the anthropogenically generated ozone 'hole'. These chapters consider UV radiation effects at a diversity of levels from the biochemical to the community. Their purpose is to provide the reader with our current understanding of the ecological effects of UV radiation, the areas where questions still remain and to provide a perspective from which the reader can better understand questions in evolutionary photobiology. The final chapter investigates the biological consequences of altered extraterrestrial ultraviolet fluxes, which are quite different from those experienced on the Earth. Our knowledge of the role of UV radiation in shaping ecologies and evolutionary change is still in its infancy. This book brings together a number of authors with the aim of helping to consolidate a better understanding of this interesting area of photobiology.

R1,918 Discovery Miles 19 180 Ships in 12 - 17 working days

This book presents the results from the Japanese Fisheries Research Agency's 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments after the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in March 2011. The book reveals the dynamics of contamination processes in marine and freshwater fish, mediated by the contamination of water, sediments, and food organisms; it also clarifies the mechanisms by which large variations in the level of contamination occurs among individual fish. Most importantly, the book includes a large amount of original measurement data collected in situ and for the first time assesses diffusion of radiocesium across the Pacific using both in situ data and a numerical simulation model. Also introduced are several new approaches to evaluate the impact of the release of radionuclides, including the measurement of radiation emission from an otolith section to identify the main period of contamination in fish. The FNPP accident represents a rare instance where the environmental radioactivity level was elevated steeply through atmospheric fallout and direct discharge of radioactive water into the sea over a short period of time. Replete with precise scientific data, this book will serve as an important resource for research in fields such as fishery science, oceanography, ecology, and environmentology, and also as a solid basis for protecting fisheries from damage resulting from harmful rumors among the general public.

R2,945 Discovery Miles 29 450 Ships in 10 - 15 working days

Wetlands are very sensitive ecosystems, functioning as habitat for many organisms. Protection and regeneration of wetlands are of great importance in ecological research and in nature conservation. A great amount of research has been done on the hydrology, plants and animals in wetlands. Knowledge on soil organisms and soil ecological processes of wetlands is still lacking. This knowledge is highly needed for landscape planning purposes or climate change predictions. For climate change, trace gas emissions from wetlands are of great interest. The authors provide an overview of state-of-the-art on soil ecology of wetlands. The book is divided in the following main chapters: "Wetlands as habitats for soil organisms", "Soil ecological processes in fens and floodplains", "Carbon and nitrogen dynamics in soils with different water regimes" and "Trace gas emissions".
