Download or read book Ecological Sustainability for Non timber Forest Products written by Charlie M. Shackleton and published by Routledge. This book was released on 2015-03-24 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing knowledge about and appreciation of the importance of Non-timber Forest Products (NTFPs) to rural livelihoods in developing countries, and to a lesser extent, developed countries. However, there is also an assumption on the part of policy-makers that any harvesting of wild animal or plant products from the forests and other natural and modified ecosystems must be detrimental to the long-term viability of target populations and species. This book challenges this idea and shows that while examples of such negative impacts certainly exist, there are also many examples of sustainable harvesting systems for NTFPs. The chapters review and present coherent and scientifically sound information and case studies on the ecologically sustainable use of NTFPs. They also outline a general interdisciplinary approach for assessing the sustainability of NTFP harvesting systems at different scales. A wide range of case studies is included from Africa, Asia and South America, using plant and animal products for food, crafts, textiles, medicines and cosmetics.
Download or read book Harvesting the Biosphere written by Vaclav Smil and published by MIT Press. This book was released on 2012-12-21 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: An interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth's thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere's character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man's hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization's well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change.
Download or read book Mathematical Ecology of Populations and Ecosystems written by John Pastor and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: MATHEMATICAL ECOLOGY Population ecologists study how births and deaths affect the dynamics of populations and communities, while ecosystem ecologists study how species control the flux of energy and materials through food webs and ecosystems. Although all these processes occur simultaneously in nature, the mathematical frameworks bridging the two disciplines have developed independently. Consequently, this independent development of theory has impeded the cross-fertilization of population and ecosystem ecology. Using recent developments from dynamical systems theory, this advanced undergraduate/graduate level textbook shows how to bridge the two disciplines seamlessly. The book shows how bifurcations between the solutions of models can help understand regime shifts in natural populations and ecosystems once thresholds in rates of births, deaths, consumption, competition, nutrient inputs, and decay are crossed. Mathematical Ecology is essential reading for students of ecology who have had a first course in calculus and linear algebra or students in mathematics wishing to learn how dynamical systems theory can be applied to ecological problems.

Download or read book The Better to Eat You With written by Joel Berger and published by University of Chicago Press. This book was released on 2009-11-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: At dawn on a brutally cold January morning, Joel Berger crouched in the icy grandeur of the Teton Range. It had been three years since wolves were reintroduced to Yellowstone after a sixty-year absence, and members of a wolf pack were approaching a herd of elk. To Berger’s utter shock, the elk ignored the wolves as they went in for the kill. The brutal attack that followed—swift and bloody—led Berger to hypothesize that after only six decades, the elk had forgotten to fear a species that had survived by eating them for hundreds of millennia. Berger’s fieldwork that frigid day raised important questions that would require years of travel and research to answer: Can naive animals avoid extinction when they encounter reintroduced carnivores? To what extent is fear culturally transmitted? And how can a better understanding of current predator-prey behavior help demystify past extinctions and inform future conservation? The Better to Eat You With is the chronicle of Berger’s search for answers. From Yellowstone’s elk and wolves to rhinos living with African lions and moose coexisting with tigers and bears in Asia, Berger tracks cultures of fear in animals across continents and climates, engaging readers with a stimulating combination of natural history, personal experience, and conservation. Whether battling bureaucracy in the statehouse or fighting subzero wind chills in the field, Berger puts himself in the middle of the action. The Better to Eat You With invites readers to join him there. The thrilling tales he tells reveal a great deal not only about survival in the animal kingdom but also the process of doing science in foreboding conditions and hostile environments.
Download or read book Balancing Ecosystem Values written by and published by . This book was released on 2005 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Balancing Ecosystem Values: Innovative Experiments for Sustainable Forestry is a compendium of more than 40 contributions from Asia, Europe, and North America. The theme encompasses experiments implemented at an operational scale to test ecological, social, or economic responses to silvicultural treatments designed to balance the complex set of objectives currently targeted in sustainable forest management. Several invited and plenary papers emphasize the variety of outcomes demanded by the public, as well as the essential role that these long-term studies will play in allowing natural resource managers to make better-informed, science-based decisions. A broad spectrum of silvicultural treatments and systems are covered, as are simulation runs with different types of models and discussion about design challenges for scaling up from stands to landscapes. Diverse forest ecosystems, stand structures and plant, animal, and fungal species are also considered. The conference included 2 days in the field where participants saw several types of the comprehensive field experiments firsthand. The conference concluded with a critique from state, private, and public land managers.
Download or read book Diagnosing Wild Species Harvest written by Matti Salo and published by Academic Press. This book was released on 2013-11-20 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagnosing Wild Species Harvest bridges gaps of knowledge fragmented among scientific disciplines as it addresses this multifaceted phenomenon that is simultaneously global and local. The authors emphasize the interwoven nature of issues specific to the ecological, economic, and socio-cultural realms of wild species harvest. The book presents the diagnosing wild species harvest procedure as a universal approach that integrates seven thematic perspectives to harvest systems: resource dynamics, costs and benefits, management, governance, knowledge, spatiality, and legacies. When analyzed, these themes help to build a holistic understanding of this globally important phenomenon. Scholars, professionals and students in various fields related to natural resources will find the book a valuable resource. Wild species form important resources for people worldwide, and their harvest is a major driver of ecosystem change. Tropical forests regions, including Amazonia, are among those parts of the world where wild species are particularly important for people's livelihoods and larger economies. This book draws on tangible experiences from Amazonia, presented in lively narratives intermingling scientific information with stories of the people engaged in harvest and management of wild species. These stories are linked to relevant theory of wild species harvest and wider discussions on conservation, development, and the global quest of sustainability. - Includes research and report-style narratives describing a wide variety of concrete cases - Addresses wild species harvest from a holistic perspective including ecological, economic and socio-cultural issues, not limiting the scope to a single type of resources - Provides theoretical treatment of wild species harvest worldwide, with special emphasis in the most recent scientific understanding on the biodiversity of the Amazonian lowland region - Presents an objective viewpoint, noting problems the harvest may cause as well as its potential to contribute both to biodiversity conservation and to local livelihoods and national economies - Coherent, easily followed structure and abundant illustrations help the reader absorb central messages

Download or read book Urban Ecology in the Global South written by Charlie M. Shackleton and published by Springer Nature. This book was released on 2021-04-20 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Against the background of unprecedented rates of urbanisation in the Global South, leading to massive social, economic and environmental transformations, this book engages with the dire need to understand the ecology of such settings as the foundation for fostering sustainable and resilient human settlements in contexts that are very different to the Global North. It does so by bringing together scholars from around the world, drawing together research and case studies from across the Global South to illustrate, in an interdisciplinary and comprehensive fashion, the ecology of towns and cities in the Global South. Framed using a social-ecological systems lens, it provides the reader with an in-depth analysis and understanding of the ecological dynamics and ecosystem services and disservices within the complex and rapidly changing towns and cities of the Global South, a region with currently scarce representation in most of the urban ecology literature. As such the book makes a call for greater geographical balance in urban ecology research leading towards a more global understanding and frameworks. The book embraces the complexity of these rapid transformations for ecological and environmental management and how the ecosystems and the benefits they provide shape local ecologies, livelihood opportunities and human wellbeing, and how such knowledge can be mobilised towards improved urban design and management and thus urban sustainability.
