Download or read book Agroforestry and Biodiversity Conservation in Tropical Landscapes written by Götz Schroth and published by Island Press. This book was released on 2013-03-22 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry -- the practice of integrating trees and other large woody perennials on farms and throughout the agricultural landscape -- is increasingly recognized as a useful and promising strategy that diversifies production for greater social, economic, and environmental benefits. Agroforestry and BiodiversityConservation in Tropical Landscapes brings together 46 scientists and practitioners from 13 countries with decades of field experience in tropical regions to explore how agroforestry practices can help promote biodiversity conservation in human-dominated landscapes, to synthesize the current state of knowledge in the field, and to identify areas where further research is needed. Agroforestry and Biodiversity Conservation in Tropical Landscapes is the first comprehensive synthesis of the role of agroforestry systems in conserving biodiversity in tropical landscapes, and contains in-depth review chapters of most agroforestry systems, with examples from many different countries. It is a valuable source of information for scientists, researchers, professors, and students in the fields of conservation biology, resource management, tropical ecology, rural development, agroforestry, and agroecology.
Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Available in PDF, EPUB and Kindle. Book excerpt: This final volume in the The Conservation Atlas of Tropical Forests covers the Americas. It provides an up-to-date overview of the status of rain forests in South America, Central America, and the Caribbean. Following the format of the two previous volumes The Conservation Atlas of Tropical Forests: Asia and the Pacific (1991) and The Conservation Atlas of Tropical Forests: Africa (1992), the atlas is divided into two parts. Part I introduces and discusses the complex interrelated issues in the regions that are involved in both deforestation as well as conservation of the tropical forests. Included are discussions on the history of the forests, agricultural colonization policies and deforestation, conservation polices for plants and wildlife, protected areas, and the future of the tropical forests. Part II is a detailed and well referenced country-by-country analysis of conservation status and trends. Four-colour maps have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies.

Download or read book Coastal Resource Management in the Wider Caribbean written by Yvan Breton and published by IDRC. This book was released on 2006 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: During Phase I, results of the project were summarised in individual case studies. In Phase II, more structured exchanges produced collective writing efforts, which gave the study a stronger comparative and analytical orientation. In addition to chapters dealing with analytical and methodological issues in coastal management, the essence of the volume lies in five comparative and synthesised case studies that focus on particular management problems in diverse social contexts. Although this text is written primarily for a research audience, it should be of interest to coastal planners, decision makers, and funding agency representatives because this type of thinking needs to be shared far more widely among these groups in the Caribbean. For instance, we argue that particular attention should be given to reaching a better balance between natural and social sciences in the management of natural resources.

Download or read book The Energetics of Mangrove Forests written by Daniel Alongi and published by Springer Science & Business Media. This book was released on 2009-01-18 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their importance in sustaining livelihoods for many people living along some of the world’s most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against coastal erosion. This book presents a functional overview of mangrove forest ecosystems; how they live and grow at the edge of tropical seas, how they play a critical role along most of the world’s tropical coasts, and how their future might look in a world affected by climate change. Such a process-oriented approach is necessary in order to further understand the role of these dynamic forests in ecosystem function, and as a first step towards developing adequate strategies for their conservation and sustainable use and management. The book will provide a valuable resource for researchers in mangrove ecology as well as reference for resource managers.

Download or read book One Billion Hungry written by Gordon Conway and published by Cornell University Press. This book was released on 2012-10-15 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunger is a daily reality for a billion people. More than six decades after the technological discoveries that led to the Green Revolution aimed at ending world hunger, regular food shortages, malnutrition, and poverty still plague vast swaths of the world. And with increasing food prices, climate change, resource inequality, and an ever-increasing global population, the future holds further challenges.In One Billion Hungry, Sir Gordon Conway, one of the world's foremost experts on global food needs, explains the many interrelated issues critical to our global food supply from the science of agricultural advances to the politics of food security. He expands the discussion begun in his influential The Doubly Green Revolution: Food for All in the Twenty-First Century, emphasizing the essential combination of increased food production, environmental stability, and poverty reduction necessary to end endemic hunger on our planet. Conway addresses a series of urgent questions about global hunger: • How we will feed a growing global population in the face of a wide range of adverse factors, including climate change? • What contributions can the social and natural sciences make in finding solutions?• And how can we engage both government and the private sector to apply these solutions and achieve significant impact in the lives of the poor?Conway succeeds in sharing his informed optimism about our collective ability to address these fundamental challenges if we use technology paired with sustainable practices and strategic planning.Beginning with a definition of hunger and how it is calculated, and moving through issues topically both detailed and comprehensive, each chapter focuses on specific challenges and solutions, ranging in scope from the farmer's daily life to the global movement of food, money, and ideas. Drawing on the latest scientific research and the results of projects around the world, Conway addresses the concepts and realities of our global food needs: the legacy of the Green Revolution; the impact of market forces on food availability; the promise and perils of genetically modified foods; agricultural innovation in regard to crops, livestock, pest control, soil, and water; and the need to both adapt to and slow the rate of climate change. One Billion Hungry will be welcomed by all readers seeking a multifaceted understanding of our global food supply, food security, international agricultural development, and sustainability.
Download or read book Agroforestry Parklands in Sub Saharan Africa written by Jean-Marc Boffa and published by Food & Agriculture Org.. This book was released on 1999 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document attempts to present the current state of knowledge on agroforestry parkland systems. These systems, which for many local populations are very important for food security, income generation and environmental protection, are found primarily in the semi-arid and sub-humid zones of West Africa. The document first provides a thorough description of their distribution and diversity and discusses different ways of classifying them. It also presents data on current trends in parkland development and assesses determining factors. The document then provides an in-depth analysis of biophysical tree-soil-crop interactions and the factors regulating them, and describes various improved parkland management techniques. It goes on to examine the strength and limitations of institutional arrangements as well as the constraints imposed by Sahelian forest policies on the sustainable management of parklands. The production, use and marketing of parkland products is reviewed with an emphasis on their contribution to food security, local and national income as well as social values. Overall costs and benefits of the practice of parkland agroforestry are evaluated. In conclusion, the document identifies crucial research needs and promising avenues for promoting sustainable management of parkland systems.
Download or read book North American Agroforestry written by Harold E. Gene Garrett and published by John Wiley & Sons. This book was released on 2022-02-23 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.
Download or read book Phenology An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology is the study of plant and animal life cycle events, which are triggered by environmental changes, especially temperature. Wide ranges of phenomena are included, from first openings of leaf and flower buds, to insect hatchings and return of birds. Each one gives a ready measure of the environment as viewed by the associated organism. Thus, phenological events are ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing and other areas. This book is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students and interested members of the public. With contributions from a diverse group of over fifty phenological experts, covering data collection, current research, methods and applications, it demonstrates the accomplishments and potential of phenology as an integrative environmental science.
Download or read book Economic and Ecological Significance of Arthropods in Diversified Ecosystems written by Akshay Kumar Chakravarthy and published by Springer. This book was released on 2016-10-20 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.
