Download or read book Agroforestry Science Policy and Practice written by Fergus L. Sinclair and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century. It is now necessary to consolidate the scientific gains now being made in process-oriented research and to develop a policy framework to encourage the adoption of sustainable land use practices. Agroforestry plays an important role in conserving forest resources, reducing the need for deforestation. Further, if `forest' is broadly defined as tree cover, agroforestry will also increase the proportion of woody biomass in farming landscapes. The papers selected for inclusion in Agroforestry: Science, Policy, and Practice establish agroforestry as an interdisciplinary science focused on the practical imperative of assisting farmers, forest dwellers and landscape-level planners to achieve sustainable food, fuel and timber production into the 21st century.

This book was released on 2013-04-18 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large areas of the warm, humid tropics in Southeast Asia, the Pacific, Latin America, the Caribbean, and Africa are hilly or mountainous. Jackson and Scherr (1995) estimate that these tropical hillside areas are inhabited by 500 million people, or one-tenth of the current world population, many of whom practice subsistence agriculture. The region most affected is Asia which has the lowest area of arable land per capita. Aside from limited areas of irrigated terraces, most of the sloping land, which constitutes 60% to 90% of the land resources in many Southeast Asian countries, has been by-passed in the economic development of the region (Maglinao and Hashim, 1993). Poverty in these areas is often high, in contrast to the relative wealth of irri gated rice farms in lowland areas that benefited from the green revolution. Rapid population growth in some countries is also exacerbating the problems of hillside areas. Increasingly, people are migrating from high-potential lowland areas where land is scarce to more remote hillside areas. Such migra tion, together with inherent high population growth, is forcing a transforma tion in land use from subsistence to permanent agriculture on fragile slopes, and is creating a new suite of social, economic, and environmental problems (Garrity, 1993; Maglinao and Hashim, 1993).
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 Biodiversity of Vegetation and Flora in Tropical Africa written by Lúıs Catarino and published by MDPI. This book was released on 2020-12-03 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: African ecosystems comprise a wealthy repository of biodiversity, with a high proportion of native and endemic plant species, which makes them biologically unique and providers of a wide range of ecosystem services. A large part of African populations, in both rural and urban areas, depend on plants for their survival and welfare, but many ecosystems are being degraded, mostly due to the growing impacts of climate change and other anthropogenic actions and environmental problems. Loss of habitat and biodiversity affects livelihoods, water supply and food security and reduces the resilience of ecosystems in the African continent. The knowledge about the great African plant and ecosystem diversity, and the structure, composition and processes involved in vegetation dynamics, is crucial to promote their sustainable use and to preserve one of the most understudied regions in the world. This Special Issue aimed to gather contributions that update and improve such knowledge.
Download or read book Agroforestry for Degraded Landscapes written by Jagdish Chander Dagar and published by Springer Nature. This book was released on 2021-01-04 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents various aspects of agroforestry research and development, as well as the latest trends in degraded landscape management. Over the last four decades, agroforestry research (particularly on degraded landscapes) has evolved into an essential problem-solving science, e.g. in terms of sustaining agricultural productivity, improving soil health and biodiversity, enhancing ecosystem services, supporting carbon sequestration and mitigating climate change. This book examines temperate and tropical agroforestry systems around the world, focusing on traditional and modern practices and technologies used to rehabilitate degraded lands. It covers the latest research advances, trends and challenges in the utilization and reclamation of degraded lands, e.g. urban and peri-urban agroforestry, reclamation of degraded landscapes, tree-based multi-enterprise agriculture, domestication of high-value halophytes, afforestation of coastal areas, preserving mangroves and much more. Given its scope, the book offers a valuable asset for a broad range of stakeholders including farmers, scientists, researchers, educators, students, development/extension agents, environmentalists, policy/decision makers, and government and non-government organizations.

Download or read book An Introduction to Agroforestry written by P. K. Ramachandran Nair and published by Springer Nature. This book was released on 2022-01-12 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry – the practice of growing trees and crops in interacting combinations – is recognized the world over as an integrated approach to sustainable land-use. Agroforestry systems, being multifunctional, facilitate not only the production of food and wood products but also provide a variety of ecosystem services such as climate-change mitigation, biodiversity conservation, and soil quality improvement. Agroforestry research has made rapid strides since organized efforts started in the late 1970s. Today, a vast body of scientific knowledge and an impressive array of publications on agroforestry are available. Four World Congresses on Agroforestry conducted once every five years since 2004 have brought together the global community of agroforestry professionals and practitioners to share and discuss the emerging trends and paradigm shifts in this field. The fifth Congress is scheduled to be held in Québec, Canada. However, a comprehensive college-level textbook incorporating these research findings did not exist until this book was first published. The first edition of this book in 1993 (Nair, P. K. R., 1993) is out of print and somewhat dated. This revised edition, with emphasis on the scientific developments during the past more than four decades, addresses this long-felt need.
Download or read book Sustainable Development in Third World Countries written by Valentine U. James and published by Bloomsbury Publishing USA. This book was released on 1996-02-13 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development has been approached from many viewpoints over the past 15 years without a concise or precise definition of what sustainable development really stands for. James has solicited contributions from an international group of experts who write about aspects of sustainable development from many different disciplines. Their consensus is that sustainability depends upon concerted development across the spectrum of socioeconomic factors that affect the environment, natural resources, health, education, and welfare of the populations in the emerging nations. The necessity of incorporating indigenous knowledge with technological and international expertise has become crucial.
