Biology and Management of the World Tarpon and Bonefish Fisheries (Hardcover): Jerald S. Ault Biology and Management of the World Tarpon and Bonefish Fisheries (Hardcover)
Jerald S. Ault
R5,125 Discovery Miles 51 250 Ships in 12 - 17 working days

The core of a multibillion dollar sport fishing industry, tarpon and bonefish, two of the earth's oldest creatures, are experiencing obvious and precipitous population decline. Experienced anglers in the Florida Keys suggest a drop of approximately 90-95 percent for the bonefish population over the last 65 years. Despite the economic value of the industry and scientific value of these ancient fish, very little information is available about their movements and migrations, population dynamics, life histories, and reproductive habits. With contributions from some of the world's leading experts, Biology and Management of the World Tarpon and Bonefish Fisheries synthesizes existing scientific literature, presents new perspectives, and introduces original scientific research to guide fishery management and conservation efforts for building sustainable fisheries. Divided into five sections, the book begins with an overview of the state of the world's fisheries for tarpon and bonefish. The second section reviews the biology and life history dynamics of these fish with contributions on conservation genetics, reproductive biology and early life development, as well as resolving gaps in evolutionary lineage and taxonomy. Covering population dynamics and resource ecology, the third section discusses migratory patterns and the use of tagging. Highlighting the lore and appeal of these fascinating sport fish, the book concludes by introducing a myriad of proposals designed to improve fishery sustainability by conducting census, enforcing catch-and-release programs, and supporting science-based management decision making. Promoting a better understanding of the biological and fishery management issues that are paramount to the sustainable future of these valuable fishery resources, Biology and Management of the World Tarpon and Bonefish Fisheries provides a foundation for discussion and broad communication about the past present and future of these magnificent fish.

A Place like No Other - Discovering the Secrets of Serengeti (Hardcover): Anthony R. E. Sinclair A Place like No Other - Discovering the Secrets of Serengeti (Hardcover)
Anthony R. E. Sinclair; As told to Rene Beyers
R733 Discovery Miles 7 330 Ships in 12 - 17 working days

From famed zoologist Anthony Sinclair, an account of his decades-long quest to understand one of Earth's most spectacular ecosystems With its rich biodiversity, astounding wildlife, and breathtaking animal migrations, Serengeti is like no other ecosystem on the planet. A Place like No Other is Anthony Sinclair's firsthand account of how he and other scientists discovered the biological principles that regulate life in Serengeti and how they rule all of the natural world. When Sinclair first began studying this spectacular ecosystem in 1965, a host of questions confronted him. What environmental features make its annual migration possible? What determines the size of animal populations and the stunning diversity of species? What factors enable Serengeti to endure over time? In the five decades that followed, Sinclair and others sought answers. What they learned is that seven principles of regulation govern all natural processes in the Serengeti ecosystem. Sinclair shows how these principles can help us to understand and overcome the challenges facing Serengeti today, and how they can be used to repair damaged habitats throughout the world. Blending vivid storytelling with invaluable scientific insights from Sinclair's pioneering fieldwork in Africa, A Place like No Other reveals how Serengeti holds timely lessons for the restoration and conservation of our vital ecosystems.

Forestry in the Midst of Global Changes (Hardcover): Christine Farcy, Inazio Martinez de Arano, Eduardo Rojas-Briales Forestry in the Midst of Global Changes (Hardcover)
Christine Farcy, Inazio Martinez de Arano, Eduardo Rojas-Briales
R5,112 Discovery Miles 51 120 Ships in 12 - 17 working days

Forestry today, like many other sectors that traditionally rely on material goods, faces significant global drivers of societal change that are less often addressed than the environmental concerns commonly in the spotlight of scientific, political, and news media. There are three major interconnected issues that are challenging forestry at its foundation: urbanization, tertiarization, and globalization. These issues are at the core of this book. The urbanization of society, a process in development from the first steps of industrialization, is particularly significant today with the predominance and quick growth rate of the world's urban population. Ongoing urbanization is creating new perspectives on forestry, inducing changes in its social representation, and changing lifestyles and practices with a tendency toward dematerialization. The process of urbanization is also creating a disconnect and in some ways is leaving behind rurality, the sector of society where forestry has traditionally developed and taken place over centuries. The second issue covered in this book is the tertiarization of the economy. In society today, the sector of services largely dominates the economy and occupies the major part of the world's active population. This ongoing process modifies professional modalities and ways of life and opens new doors to forests through the immaterial goods they provide. It also profoundly changes the framework, rules, processes, means of production, exchanges between economic factors, and the processes of innovation. The third issue is undoubtedly globalization in its economic, political, and social components. Whether it's through bridging distances, crossing borders, accelerating changes, standardizing practices, leveling hierarchical structures, or pushing for interdependence, globalization impacts everyone, everywhere in multiple ways. Forestry is no exception. Forestry in the Midst of Global Changes focuses on these global drivers of change from the perspective of their relationships with how society functions. By analyzing them in depth through multidisciplinary, interdisciplinary, and even transdisciplinary approaches, this book is helping to design the forestry of tomorrow.

Redesigning the Global Seed Commons - Law and Policy for Agrobiodiversity and Food Security (Hardcover): Christine Frison Redesigning the Global Seed Commons - Law and Policy for Agrobiodiversity and Food Security (Hardcover)
Christine Frison
R3,926 Discovery Miles 39 260 Ships in 12 - 17 working days

There is much current controversy over whether the rights to seeds or plant genetic resources should be owned by the private sector or be common property. This book addresses the legal and policy aspects of the multilateral seed management regime. First, it studies in detail the International Treaty on Plant Genetic Resources for Food and Agriculture (the Treaty) in order to understand and identify its dysfunctions. Second, it proposes solutions - using recent developments of the "theory of the commons" - to improve the collective seed management system of the Treaty, a necessary condition for its member states to reach the overall food security and sustainable agriculture goals. Redesigning the Global Seed Commons provides a significant contribution to the current political and academic debates on agrobiodiversity law and governance, and on food security and food sovereignty, by analyzing key issues under the Treaty that affect the design and implementation of regulatory instruments managing seeds as a commons. It also examines the practical, legal, political and economic problems encountered in the attempt to implement these obligations in contemporary settings. In particular, it considers how to improve the Treaty implementation by proposing ways for Contracting Parties to better reach the Treaty's objectives taking a holistic view of the human-seed ecosystem. Following the tenth anniversary of the functioning the Treaty's multilateral system of access and benefit-sharing, which is currently under review by its Contracting Parties, this book is well-timed to examine recent developments in the field and guide the current review process to design a truly Global Seed Commons.

In Silico Bees (Paperback): James Devillers In Silico Bees (Paperback)
James Devillers
R1,777 Discovery Miles 17 770 Ships in 12 - 17 working days

Bees are critically important for ecosystem function and biodiversity maintenance through their pollinating activity. Unfortunately, bee populations are faced with many threats, and evidence of a massive global pollination crisis is steadily growing. As a result, there is a need to understand and, ideally, predict how bees respond to pollution disturbance, to the changes over landscape gradients, and how their responses can vary in different habitats, which are influenced to different degrees by human activities. Modeling approaches are useful to simulate the behavior of whole population dynamics as well as to focus on important phenomena detrimental to bee-life history traits. They also allow simulation of how a disease or a pesticide can impact the survival and growth of a bee population. In Silico Bees provides a collection of computational methods to those primarily interested in the study of the ecology, ethology, and ecotoxicology of bees. The book presents different cases studies to enable readers to understand the significance and also the limitations of models in theoretical and applied bee research. The text covers modeling of honey bee society organization, infectious diseases in colonies, pesticide toxicity, chemical contamination of the hive, and more. Written by an international team of scientists, this book is of primary interest to those whose research or professional activity is directly concerned with the study of bees. It is also intended to provide graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches that can be used in terrestrial ecology and ecotoxicology.

Communities Surviving Migration - Village Governance, Environment and Cultural Survival in Indigenous Mexico (Hardcover): James... Communities Surviving Migration - Village Governance, Environment and Cultural Survival in Indigenous Mexico (Hardcover)
James P. Robson, Dan Klooster, Jorge Hernandez Diaz
R3,913 Discovery Miles 39 130 Ships in 12 - 17 working days

Out-migration might decrease the pressure of population on the environment, but what happens to the communities that manage the local environment when they are weakened by the absence of their members? In an era where community-based natural resource management has emerged as a key hope for sustainable development, this is a crucial question. Building on over a decade of empirical work conducted in Oaxaca, Mexico, Communities Surviving Migration identifies how out-migration can impact rural communities in strongholds of biocultural diversity. It reflects on the possibilities of community self-governance and survival in the likely future of limited additional migration and steady - but low - rural populations, and what different scenarios imply for environmental governance and biodiversity conservation. In this way, the book adds a critical cultural component to the understanding of migration-environment linkages, specifically with respect to environmental change in migrant-sending regions. Responding to the call for more detailed analyses and reporting on migration and environmental change, especially in contexts where rural communities, livelihoods and biodiversity are interconnected, this volume will be of interest to students and scholars of environmental migration, development studies, population geography, and Latin American studies.

R1,481 Discovery Miles 14 810 Ships in 12 - 17 working days

This book is a product of the TEEB study (The Economics of Ecosystems and Biodiversity). It provides important evidence of growing corporate concern about biodiversity loss and offers examples of how leading companies are taking action to conserve biodiversity and to restore ecosystems. This book reviews indicators and drivers of biodiversity loss and ecosystem decline, and shows how these present both risks and opportunities to all businesses. It examines the changing preferences of consumers for nature-friendly products and services, and offers examples of how companies are responding. The book also describes recent initiatives to enable businesses to measure, value and report their impacts and dependencies on biodiversity and ecosystem services. The authors review a range of practical tools to manage biodiversity risks in business, with examples of how companies are using these tools to reduce costs, protect their brands and deliver real business value. The book also explores the emergence of new business models that deliver biodiversity benefits and ecosystem services on a commercial basis, the policy enabling frameworks needed to stimulate investment and entrepreneurship to realize such opportunities, and the obstacles that must be overcome. The book further examines how businesses can align their actions in relation to biodiversity and ecosystem services with other corporate responsibility initiatives, including community engagement and poverty reduction. Finally, the book concludes with a summary and recommendations for action.

R1,508 Discovery Miles 15 080 Ships in 12 - 17 working days

There is a considerable gap between the science of conservation biology and the design and execution of biodiversity conservation projects in the field. Science is often failing to inform the practice of conservation, which remains largely experience-based. The main reason is the poor accessibility of evidence on the effectiveness of different interventions. This is the basis for this book adopting an 'evidence-based approach', modelled on the systematic reviews used in health sciences and now being applied to many policy arenas. Evidence-based Conservation brings together a series of case studies, written by field practitioners, that provides the evidence-base for evaluating how effective conservation and poverty alleviation strategies can be better implemented. A series of systematic reviews uses experiences and data from fifteen integrated conservation and development projects conducted in the Lower Mekong region, specifically in Vietnam, Laos and Cambodia. They provide wide-ranging overviews of the effectiveness of protected areas and how innovative tools and methods for monitoring and evaluation can be utilised for more effective outcomes. Results are in the form of management and policy recommendations, based on the quality of evidence and the cost-utility of the intervention. By bridging the gap between field practice and conservation, the analysis should lead to more effective integrated conservation and development interventions. The book represents one of the first attempts to apply the evidence-based approach to conservation and development.

Nature's Matrix - Linking Agriculture, Biodiversity Conservation and Food Sovereignty (Hardcover, 2nd edition): Ivette... Nature's Matrix - Linking Agriculture, Biodiversity Conservation and Food Sovereignty (Hardcover, 2nd edition)
Ivette Perfecto, John Vandermeer, Angus Wright
R4,070 Discovery Miles 40 700 Ships in 12 - 17 working days

When first published in 2009, Nature's Matrix set out a radical new approach to the conservation of biodiversity. This new edition pushes the frontier of the biodiversity/agriculture debate further, making an even stronger case for the need to transform agriculture and support small- and medium-scale agroecology and food sovereignty. In the first edition, the authors set out a radical new approach to the conservation of biodiversity. This is based on the concept of a landscape as a matrix of diverse, small-scale agricultural ecosystems, providing opportunities to enhance conservation under the stewardship of local farmers. This contrasts with the alternative view of industrial-scale farms and large protected areas which exclude local people. However, since then the debate around conservation and agriculture has developed significantly and this is reflected in this updated second edition. The text is thoroughly revised, including: a reorganization of chapters with new and timely topics introduced, updates to the discussion of agroecology and food sovereignty, bringing it in line with the current debates, greater coverage of the role of agroecology, in particular agroforestry, as an important component of climate change adaptation and mitigation, highlighting recent studies on the role of intensive agriculture in climate change and loss of biodiversity, and more attention given to the discussion of land sparing versus land sharing. By integrating the ecological aspects of agriculture and conservation biology, with a political and social analysis as well as historical perspective, the book continues to set a progressive agenda and appeals to a wide range of students and professionals.

Joyce D'Silva, Jacky Turner
R1,367 Discovery Miles 13 670 Ships in 12 - 17 working days

* The complexities of animal behavior revealed in the last few decades are astonishing, but what are the implications? * Do animals experience the world in a similar way to humans, and do they have a similar capacity for suffering and enjoyment? If they do, does it matter? * Should we mind that farmed animals can be confined all their lives and are sacrificed for human consumption? * Humans have long used animals for social and economic purposes, but should we, and can we afford to, think about it and make changes? * The use of animals for meat, for hide, for their labor and in laboratories has been justified with the assumption that unlike humans, animals aren't fully sentient beings. * This book challenges that assumption with groundbreaking new research that brings into question everything we've ever thought about the ways animals experience the world. * Over twenty contributions from internationally-renowned experts on animal behavior and agriculture, including big names such as Jane Goodall, Tim Lang, and Vandana ShivaIn this book, internationally respected contributors are brought together for the first time to debate and attempt to answer these questions. The first sections discuss scientific and ethical perspectives on the consciousness, emotions, and mental abilities of animals. Later sections address how human activities such as science, law, farming, food production, trade, development, and education respect or ignore animals' sentience and welfare, and review the options for changes in our thinking, policies, and practices.Published with Compassion in World Farming Trust.

Tapestry Lawns - Freed from Grass and Full of Flowers (Hardcover): Lionel Smith Tapestry Lawns - Freed from Grass and Full of Flowers (Hardcover)
Lionel Smith
R4,960 Discovery Miles 49 600 Ships in 12 - 17 working days

Swathes of the human world are covered in ornamental grass lawns; they are the single most commonly encountered horticultural feature on the planet. Unfortunately, they are now often viewed as resource-draining green deserts due to the lack of plant and animal diversity, the need for frequent mowing and watering, and addition of lawn greening products to keep them looking at their best. It is a venerable horticultural feature that is essentially frozen in time, and with few alternatives to whet the appetite, the lawn has languished in its current grass-only format for decades. Until now. Tapestry lawns are a new, practically researched and timely development of the ornamental lawn format that integrates both horticultural practice and ecological science and re-determines the potential of a lawn. Mown barely a handful of times a year and with no need for fertilisers or scarifying, tapestry lawns are substantially richer in their diversity of plant and animal life compared to traditional grass-only lawns and see the return of flowers and colour to a format from which they are usually purposefully excluded. Tapestry Lawns: Freed from Grass and Full of Flowers traces the changes in the lawn format from its origins to the modern day and offers information on how and why the tapestry lawn construct is now achievable. It provides guidance on how to create and maintain a tapestry lawn of your own and champions the potential benefits for wildlife that can follow. Features Accessible and informative to all types of readers from academic to amateur Includes a refined and tested set of useful tapestry lawn plants Contains step-by-step instructions for creation and management methods of grass-free lawns Illustrated in full colour If you have ever thought about mowing your lawn much less, making it much more colourful and wildlife friendly, then this book will inform and guide you to create a perfect, grass-free lawn.

R350 R273 Discovery Miles 2 730 Save R77 (22%) Ships in 5 - 10 working days

This book intensively covers a never-before-explored aspect of Southern African nature and is an essential new addition to the library of every nature lover. It was researched and written over the last four and a half years to open a door to a little known micro-world that exists all around us. Invertebrates – which include commonly seen creatures such as butterflies, spiders, beetles, worms and scorpions – are everywhere. The signs of their day-to-day activities are all around us if we know where to look.

The life cycles and behaviours of many animals are discussed, with a special focus on interactions between mammals and invertebrates – a fascinating subject in itself.

While working on this book, Lee Gutteridge spent many hours in the field with expert entomologists and arachnologists, many of whom commented that; even though they had spent a lifetime in the field, this experience, of invertebrate tracking, had changed the way that they see the invertebrate world.

With funding received from the Oppenheimer family, 250 copies will be donated to indigenous trackers, whose knowledge Lee appreciates and respects.

Unstructured Cellular Automata in Ecohydraulics Modelling (Hardcover): Yuqing Lin Unstructured Cellular Automata in Ecohydraulics Modelling (Hardcover)
Yuqing Lin
R3,028 Discovery Miles 30 280 Ships in 12 - 17 working days

The field of ecohydraulics integrates hydrodynamic and eco-dynamic processes. While hydrodynamic processes are usually well described by partial differential equations (PDE's) based on physical conservation principles, ecosystem dynamics often involve specific interactions at the local scale. Because of this, Cellular Automata (CA) are a viable paradigm in ecosystem modelling. All cells in a CA system update their states synchronously at discrete steps according to simple local rules. The classical CA configuration consists of uniformly distributed cells on a structured grid. But in the field of hydrodynamics, the use of unstructured grids has become more and more popular due to its flexibility to handle arbitrary geometries. The main objective of this research is to identify whether the CA paradigm can be extended to unstructured grids. To that end the concept of Unstructured Cellular Automata (UCA) is developed and various UCA configurations are explored and their performance investigated. The influence of cell size was analyzed in analogy with the Finite Volume Method. A characteristic parameter -min distance of UCA- was put forward and tested by numerical experiments. Special attention was paid to exploring the analogies and differences between the discrete CA paradigm and discrete numerical approximations for solving PDE's. The practical applicability of UCA in ecohydraulics modelling is explored through a number of case studies and compared with field measurements.

Finding Resilience - Change and Uncertainty in Nature and Society (Paperback): Brian Walker Finding Resilience - Change and Uncertainty in Nature and Society (Paperback)
Brian Walker
R1,272 Discovery Miles 12 720 Ships in 9 - 15 working days

Floods, fires, famines, epidemics and disasters of all kinds are on the increase, and as their frequency rises so does the call for greater resilience. But what does that mean? The word is used differently in psychology, ecology, economics and engineering and runs the risk of becoming meaningless jargon. This would be most unfortunate because, if we are to successfully navigate very real and dangerous global trends, it is resilience that needs to be understood and fostered. Finding Resilience is international in scope and unravels how ecosystems, societies and people cope with disturbance and adversity. Written for a general readership and based on the experiences of researchers, the fascinating stories from around the world reveal what resilience is, how it works in different kinds of systems, how it is expressed, and how it can be gained and lost.

R1,452 Discovery Miles 14 520 Ships in 9 - 15 working days

Learn how the principles and practices of landscape agroecology can help to overcome drought, flooding, poor soil, damaging winds, plant diseases, plant-eating insects, and more! Examining the concepts, conventions, and components that underlie the ecology of human-managed landscapes, this is the first book to address landscape agroecology. Incorporating ideas from agroecology, forestry, agronomy, agroforestry, landscape ecology, and environmental science, Landscape Agroecology is a comprehensive look at a cutting-edge topic. From the author: Farm or forestry landscapes can be designed to address any number of objectives. Commonly, the focus is entirely on production with few, if any, secondary goals. These landscapes typically achieve their purpose but are not entirely in harmony with nature. Landscape agroecology offers the same potential for productivity, but also focuses on sustainability and environmental friendliness as strong secondary objectives. While the idea of formulating landscapes for specific purposes is comparatively new, countless examples exist where landscape modifications have been made to inhospitable areas in order to overcome the natural obstacles that hamper crop growth. This book illuminates the principles behind these triumphs, bringing this local knowledge into the mainstream. Landscape Agroecology will familiarize you with the concepts and terminology needed to understand this exciting new field: complementarityusually defined in terms of plant-plant growthexpanded to include the rural countryside desirable agroecosystems propertieswhat an agroecosystem needs in order to overcome landscape stresses such as drought, flooding, insect infestation, etc. agrotechnologiesthe classification of agroecosystems based on visual characteristics and the land-use problems addressed cultural agroecologywhat we can learn from the superior land-use techniques of various societies and cultures, and how these ideas can be brought into the mainstream cultural motifculturally related land-use patterns that are openly manifested in the landscape Essential for university/college libraries and for research stations as well as professors and students of agroecology, this book will be referred to again and again. In addition to basic agroecological concepts, chapters in this essential book address the management of wind, water, and pests; biodiversity; physical and temporal patterns; principal, auxiliary, and temporal agrotechnologies, and much more. For professors and students in environmental science, this book offers many previously un-dicussed alternatives for resolving the earth's environmental dilemmas. Photographs, tables, figures, and illustrations help make important points easy to access and understand.

Sharks in the Arts - From Feared to Revered (Hardcover): Vivienne Westbrook, Shaun Collin, Dean Crawford, Mark Nicholls Sharks in the Arts - From Feared to Revered (Hardcover)
Vivienne Westbrook, Shaun Collin, Dean Crawford, Mark Nicholls
R3,913 Discovery Miles 39 130 Ships in 12 - 17 working days

This book is the most thorough exploration to date of the many ways in which a wild creature has been absorbed, reimagined and represented across the ages in all of the major art forms. The authors consider not only how the identity of sharks in the natural environment became incorporated into a cultural environment but also how sharks came to be considered the most feared creatures in the open oceans as a consequence of this incorporation. Yet sharks are especially important in helping to maintain a balance that is essential to the health of the oceans. The book begins with a treatment of the three sharks at the top of global shark-attack files from scientific, economic and environmental perspectives. Subsequent chapters engage with cultural representations of sharks in poetry, drama, art, novels, screenplay adaptations and films. Through an exploration of the ways in which sharks have been represented in human culture through the centuries, this book alerts the global community to the importance of sharks as a common cultural heritage. It aims to change perceptions of sharks so that they can become more revered than feared. The authors of this book argue that an increased understanding of sharks should lead to the development of better strategies for shark and human interactions. This book will be of great interest to researchers and students of the Environmental Humanities, Cultural History and the Arts. It is also excellent supplementary reading for courses in Zoology and Marine Science.

R5,220 Discovery Miles 52 200 Ships in 12 - 17 working days

"RFF's Roger Sedjo and his colleagues discuss initiatives designed to promote and enhance sustainable forestry in temperate countries. While concerns about tropical deforestation are considerable, temperate forests account for the vast majority of the world's roundwood production and most global trade in wood and paper. Improving forest sustainability in such regions is imperative, economically and environmentally. This book illustrates how far nations have progressed, and how far they still need to go, in that effort. The authors describe how temperate nations address forest sustainability, discussing recent developments affecting forestry and trade. Their compilation of international data on forest practices and regulation provides a useful comparative perspective. They analyze the effect of institutional changes (e.g., new laws) on land management. The volume assesses how national forestry industries are adapting to new laws and policies in the face of new realities in production and markets, particularly in the context of international trade and global competition. Country profiles provide details on sustainability policy and performance in eight timber-exporting or major wood-using temperate nations: the United States, Canada, Finland, Sweden, Germany, France, New Zealand, and Chile. The authors also assess how each nation would be affected by the application of various criteria for sustainability."

The management of common pool resources and publicly-owned areas is fraught with difficulty. This book explores the long, complex, and frequently contentious history of public lands management in the United States in order to draw lessons for the emerging field of marine spatial planning (MSP). The author first establishes that these two seemingly different settings are in fact remarkably similar, drawing on established theories of policy analysis. The work then examines the management of US National Forests over the past 120 years, including three place-based case studies, to discover recurring themes. The analysis shows how different management approaches evolved over time in response to changing laws and cultural norms, producing outcomes favored by different constituencies. This history also reveals the ambiguities and contradictions inherent in multiple-use management of any public space. Next, the book analyzes recent efforts to advance MSP, both in the US and globally, showing how they mirror past experiences in National Forest management, including similar disagreements among stakeholders. In conclusion the author suggests how those within ocean-related sectors - government, academia, industry, and environmental groups - might achieve their individual and collective goals more effectively based on lessons from the public lands setting.
