Swimming Lessons - Keeping Afloat in the Age of Technology (Hardcover): David Ehrenfeld Swimming Lessons - Keeping Afloat in the Age of Technology (Hardcover)
David Ehrenfeld
R731 Discovery Miles 7 310 Ships in 10 - 15 working days

David Ehrenfeld is a highly esteemed writer on ecology and conservation biology. The founding editor of The Journal of Conservation Biology and author of The Arrogance of Humanism and Beginning Again, his new book is an elegant study of the cost to human dignity and potential, of the shrinking wilderness and the ongoing degredation of the environment. He ruminates on the impacts of short-sighted governmental and economic policies, and of new technologies on human values and communities, tracing the human impacts upon the urban, agricultural and wilderness environments. Ehrenfeld has a unique, unmistakable voice as a major spokesperson for the conservation ethic and the human values implicit in environmentalism and conservation biology. This book should appeal strongly to readers of Ehrenfeld's earlier books and essays, and reach and satisfy a broad constituency on the green end of the political spectrum.

R4,044 Discovery Miles 40 440 Ships in 18 - 22 working days

Despite the potential benefits that PSSA designation can deliver, recent practice both within the IMO and by individual member States, has considerably undermined confidence in this emerging concept. The focus of this book is on the events within the IMO that have led to this lack of confidence arising. In doing so, this book presents an examination of coastal State practice with the PSSA concept.

In undertaking this analysis, the research provides evidence of the value of the PSSA concept, but also demonstrates its limitations. In this regard, the book presents a reality check which seeks to rationalise some of the heightened expectations with the concept that are apparent in the current debate. The research argues that States may seek to designate PSSAs more for their iconic status than for any demonstrable environmental benefits that may be realised."

R2,662 Discovery Miles 26 620 Ships in 18 - 22 working days

Water - and its governance - is becoming a global concern partly because it is turning into a goods in short supply, with devastating effects on literally billions of people, but also because it is the "carrier" ofglobal warming; whether through irregular weather patterns or through flooding, water is how global warming will be 'felt'. The lion's share of the globally available fresh water resources is to be found in transboundary systems. In spite of its significance, the generated knowledge on how to deal with transboundary waters is weak and leaves policy makers with seemingly unavoidable, trade-off dilemmas and prioritizations, often with detrimental effects. In order to disentangle this predicament this volume works with one case: the Lower Mekong Basin and covers state-of-the-art academic and practitioners' knowledge and hence appeals to a wide audience. The topic this volume addresses is situated in the nexus ofan IR- (International Relations) approach focussing on transboundary politics and its inclination to remain within the sphere of state sovereignty and national interest on the one hand, and Development studies, with its imperatives on participation, planning, and intervention, on the other.The dilemma, we argue, of better understanding transboundary water management lies in how to understand how these two rationalities can be simultaneously nurtured.
"Audience: "This book will be relevant to scholars, as it provides cutting-edge research, and students, since it covers the primary debates in the field, interested in resource management, regional politics, and development issues in the area. It also addresses the global debate on transboundary water management and presents an in-depth case of one of the globally most sophisticated attempts at pursuing sustainable river basin management. Finally, practitioners and policymakers would benefit greatly because all contributions have explicit policy relevance, launching suggestion on improvements in water management.

Environmental argument is 'about' far more than meets the eye. How people (mis)under-stand each other during environmental debates is affected by conflicts between values and ways of life which may not be directly connected with the environment at all. This book offers sociological evidence from three contrasting societies - Ireland, Germany and China - to explore how diversity of cultural context affects deliberation about the physical world. What can we discover by examining environmental debates through the lens of interculturality? When people disagree about flood management, building motorways or extracting gas, what difference does it make if they have diverse experiences of neighbourly relations, how to use time or how to imagine a good life? What is going on at intersections between cultures to influence the trajectories of environmental debates? The book disinters taken-for-granted practices, feelings and social relationships which affect environmental arguments, in scientific and artistic debate as well as in politics and policy-making. Importantly, the book makes visible the effects of cultural difference on people's approaches to arguing itself. If public arguing is shaped by specific habits of feeling or imagination, how does that impact on theories of democracy? Do we need new kinds of arguing to cope with environmental crises? What elements of arguing are decisive in the ways people come to see environmental decisions as wise choices?

Playing a critical role in both influencing climate change and mitigating its impacts, the world's diverse wetlands have become one of the world's most threatened ecosystems as unsustainable land-use practices coupled with irrational use of water have already resulted in large-scale wetlands loss and degradation. To develop sound management and conservation schemes to assure wetlands sustainability in the long term requires long-term understanding of wetlands ecology. Yet until now, long-term interdisciplinary research into these systems has been limited to only a few systems from tropical or temperate climates (such as the Florida Everglades, and Czech biosphere reserve). This new book adds to the existing wetlands literature, providing a unique reference in basic and applied Mediterranean wetland ecology, based on results from long-term interdisciplinary research at the RAMSAR and UNESCO Biosphere site, of Las Tablas de Daimiel, Spain. Dating back to the early 1990s the research highlights changes in the biotic and abiotic environment in response to cumulative anthropogenic stressors, and provide guidance on applying this understand to sound management and conservation. With particular relevance to researchers dealing with semi-arid wetlands in the Mediterranean and elsewhere, as well as to resource managers, the book discusses the complexity of the interacting abiotic and biotic environment across different spatial and temporal scales and across various levels of biological hierarchy is highlighted, and reveals how management based on poor knowledge causes more damage than repair. The book will be of interest to researchers interested in freshwater ecology, hydrobotany, hydrology, geology, biogeochemistry, landscape ecology and environmental management.

This is the fourth updated and revised edition of a well-received book that emphasises on fungal diversity, plant productivity and sustainability. It contains new chapters written by leading experts in the field. This book is an up-to-date overview of current progress in mycorrhiza and association with plant productivity and environmental sustainability. The result is a must hands-on guide, ideally suited for agri-biotechnology, soil biology, fungal biology including mycorrhiza and stress management, academia and researchers. The topic of this book is particularly relevant to researchers involved in mycorrhiza, especially to food security and environmental protection. Mycorrhizas are symbioses between fungi and the roots of higher plants. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition and the diversity of natural ecosystems are frequently dependent upon the pre sence and activity of mycorrhizas. The biotechnological application of mycorrhizas is expected to promote the production of food while maintaining ecologically and economically sustainable production systems.

The authors of this book, who represent a broad range of scientific disciplines, discuss the issue of centralized versus decentralized control and regulation in the context of sustainable development. The stability and resilience of complex technical, economic, societal and political systems are commonly assumed to be highly dependent on the effectiveness of sophisticated, mainly centralized regulation and control systems and governance structures, respectively. In nature, however, life is mainly self-regulated by widespread, mainly DNA-encoded control mechanisms. The fact that life has endured for more than 2.4 billion years suggests that, for man-made systems, decentralized control concepts are superior to centralized ones. The authors discuss benefits and drawbacks of both approaches to achieving sustainability, providing valuable information for students and professional decision makers alike.

R4,122 Discovery Miles 41 220 Ships in 18 - 22 working days

Untouched since 1953, the Korean DMZ (Demilitarized Zone) has transformed itself into one of the few ecologically pristine zones and a vital habitat for endangered species. Often cited as a potential "peace park", it could one day be a common ground for reconciliation and harmony. A wealth of data and information has been produced over time, documenting significant aspects of the DMZ and its implications for human and ecological security, both in Korea and worldwide. However, there is no single book in English that brings together the findings on the mechanism of evolution, the ecology and biodiversity of the DMZ. "The DMZ of Korea", by Kwi-Gon Kim, is the first step in this direction. It seeks to link scientific information and policy making for the future DMZ ecosystem management, taking into account the fact that the area has become, over the years, a natural treasure as a habitat for rare birds and other wildlife and a fertile environment for a thriving plant community. It also provides a framework for ensuring the long-term sustainability of the DMZ. The book holistically describes the current environmental status of the DMZ, and identifies bioregions, resources, habitats, and species. By outlining the current scientific data and information needed to classify the different wetland types, assess the biological integrity, understand the threat factors, and to suggest conservation and management strategies, the book provides a "one stop shop" scientific and policy source of information, which will undoubtedly be of great interest to students, researchers, practitioners, and policy decision-makers, in the areas of planning, natural resource management, public management, ecology, landscape architecture, geography, and the life sciences. Prof.Dr.Kwi-Gon Kim obtained his Ph.D. at UCL, University of London, UK. He is a professor emeritus at Seoul National University and the Co- President of the Korea DMZ Council in Seoul, Korea.

The Evolutionary Strategies that Shape Ecosystems (Hardcover): J Grime The Evolutionary Strategies that Shape Ecosystems (Hardcover)
J Grime
R3,404 Discovery Miles 34 040 Ships in 18 - 22 working days

In 1837 a young Charles Darwin took his notebook, wrote "I think" and then sketched a rudimentary, stick-like tree. Each branch of Darwin's tree of life told a story of survival and adaptation - adaptation of animals and plants not just to the environment but also to life with other living things. However, more than 150 years since Darwin published his singular idea of natural selection, the science of ecology has yet to account for how contrasting evolutionary outcomes affect the ability of organisms to coexist in communities and to regulate ecosystem functioning.

In this book Philip Grime and Simon Pierce explain how evidence from across the world is revealing that, beneath the wealth of apparently limitless and bewildering variation in detailed structure and functioning, the essential biology of all organisms is subject to the same set of basic interacting constraints on life-history and physiology. The inescapable resulting predicament during the evolution of every species is that, according to habitat, each must adopt a predictable compromise with regard to how they use the resources at their disposal in order to survive. The compromise involves the investment of resources in either the effort to acquire more resources, the tolerance of factors that reduce metabolic performance, or reproduction. This three-way trade-off is the irreducible core of the "universal adaptive strategy theory" which Grime and Pierce use to investigate how two environmental filters selecting, respectively, for convergence and divergence in organism function determine the identity of organisms in communities, and ultimately how different evolutionary strategies affect the functioning of ecosystems. This book reflects an historic phase in which evolutionary processes are finally moving centre stage in the effort to unify ecological theory, and animal, plant and microbial ecology have begun to find a common theoretical framework.

R6,600 Discovery Miles 66 000 Ships in 18 - 22 working days

This book provides a comprehensive overview of the benefits of biofertilizers as an alternative to chemical fertilizers and pesticides. Agricultural production has increased massively over the last century due to increased use of chemical fertilizers and pesticides, but these gains have come at a price. The chemicals are not only expensive; they also reduce microbial activity in agricultural soils and accumulate in the food chain, with potentially harmful effects for humans. Accordingly, it is high time to explore alternatives and to find solutions to overcome our increasing dependence on these chemicals. Biofertilizers, which consist of plant remains, organic matter and microorganisms, might offer an alternative. They are natural, organic, biodegradable, eco-friendly and cost-effective. Further, the microbes present in the biofertilizers are important, because they produce nutrients required for plant growth (e.g., nitrogen, phosphorus, potassium), as well as substances essential for plant growth and development (e.g., auxins and cytokinins). Biofertilizers also improve the physical properties, fertility and productivity of soil, reducing the need for chemical fertilizers while maintaining high crop yield. This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment. The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. As such, it offers a valuable resource for researchers, academics and students in the broad fields of microbiology and agriculture.

This volume presents a state-of-the-art assessment of the Earth's climate system in Siberia and relationships between climate, ecosystems and people in that region. Changes in climatic variables and land cover in Siberia are among the earliest indicators of the Earth's response to climate warming. The volume is a compilation of results from studies on climate, land-cover and land-use changes and their interactions with biogeochemical and water cycles, atmospheric aerosol, and human and wildlife populations in Siberia. Regional changes in Siberia are predicted to affect climate and people on a global scale. NASA, the Russian Academy of Sciences, and several European institutions have supported these studies. The primary supporter of the projects that produced the results compiled in this volume is the NASA Land-Cover/Land-Use Change Program, hence most studies use remote sensing in their research. The chapters in this volume were written by an international team of scientists from the USA, Europe and Russia under the auspices of the Northern Eurasia Earth Science Partnership Initiative (NEESPI). This book will be of interest to those involved in studying recent and ongoing changes in Siberia, be they senior scientists, early career scientists or students.

R4,028 Discovery Miles 40 280 Ships in 18 - 22 working days

Central Asia is vulnerable to water scarcity because it is located in semiarid and arid vegetation zones and large parts of its economy depend on water for irrigation and energy. Climate-change scenarios predict temperature increases and a rising number of extreme weather events, which will exacerbate water shortages in the future. In addition, the population of Central Asia is growing more rapidly than the rate of food production which is resulting in food insecurity in many parts of the region too. This volume reports the deliberations of politicians, scientists and representatives of water management organizations from throughout Central Asia. Their contributions not only highlight areas of concern, but also propose numerous ideas for improving the long-term water- and food security in the region.
