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).
This volume comprises a selection of original contributions presented at a workshop held in Montpellier, France, in June 1997. The two main objectives of the workshop were, firstly, to bring together what is understood about the processes underlying agroforestry practice, and, secondly, to provide a forum to explore relevant models and modelling approaches. The workshop was also able to play a role in examining the agroforestry systems encountered in temperate and Mediterranean areas, including both traditional and more innovative agroforestry practices. The main aspects discussed were: ecological interactions amongst components, environmental impact, economics and policy modelling.
For the last two decades the loss of, in particular, tropical rainforest has alarmed the public in the developed parts of the world. The debate has been characterised by a lack of understand ing of the causes and effects of the process, leading to the prevailing reaction being unquali fied condemnation. Such attitude has even been observed among scientists, claiming suprem acy to biodiversity conservation. Many scientific analyses are available, but the basis for so ber debates and appropriate actions is still highly insufficient. Two recent international initia tives! will hopefully lead to improved knowledge of deforestation and forest degradation as they recognise the need for studies to critically investigate those issues. This book will pro vide useful input to the initiatives. In my opinion, the scientific analyses have not sufficiently promoted the understanding that the fate of tropical forests is first and foremost a concern of the governments of the countries in which the forests are situated. Tropical forests may be important to the global environment and their rich biodiversity may be a human heritage. But their main importance is their poten tial contribution to improving livelihood in the countries in question.
This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.
This textbook is one of the finest books on agroforestry that offers a global review of the approaches, tools and technologies, research innovations and real-world practices in agroforestry. The book offers a comprehensive guide to basic principles, techniques and applications, integrative strategies, economic and environmental concerns, and future trends in agroforestry in different regions of the world. It will help all scientists, students, professors, farmers, foresters, decision-makers, and politicians who wish to build a safe land use system for food, energy and better environment for future generations. This textbook will enormously benefit the students for their preparation of competitive exams like UPSC-Civil Services, UPSC-Indian Forest Service, ICAR-ARS Scientist/NET Exam, ICFRE Forestry Scientist Exam, State Public Service Commission Exams and University Entrance Exam for admission to M.Sc. and Ph.D. programmes.
Agroecologists from around the world share their experiences in the analysis and development of indicators of agricultural sustainability in Agroecosystem Sustainability: Developing Practical Strategies. The authors build on the resource-conserving aspects of traditional, local, and small-scale agriculture while at the same time drawing on modern e
Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food sec
Agroforestry (AF) is a dynamic, ecologically based, natural resources management system that, by integrating trees on farms, ranches, and in other landscapes, diversifies and increases production and promotes social, economic, and environmental benefits for land users. Further, it is receiving increasing attention as a sustainable land-management option worldwide because of its ecological, economic, and social attributes. Advances have been achieved by building on past research accomplishments and expanding AF’s stakeholder base, which now includes private/public partnerships, communities, ecologists, farmers, indigenous peoples, and policymakers in both temperate and tropical countries. AF has now been recognized as a valuable problem-solving approach to ensuring food security and rebuilding resilient rural environments. Recent studies have shown that more than 1 billion hectares of agricultural land have more than 10% tree cover. Of this area, 160 million hectares have more than 50% tree cover. Agricultural ecosystems can be further improved through AF to achieve environmental restoration, greater farm productivity, and key ecological services, including climate change mitigation and adaptation for improved rural livelihood. In fact, it is largely considered synonymous with climate smart agriculture and a remedy for many modern environmental challenges. Consequently, AF’s knowledge base is being expanded at a rapid rate, as illustrated by the increasing number and quality of scientific publications on various forms and different aspects of AF. This book offers state-of-the-art information on the fundamental concepts and history of AF and its evolution as a science, presenting a wealth of advanced research results and evaluations relating to different aspects of AF. Accordingly, it will be useful for a broad readership, including students, foresters, farmers, local communities, indigenous peoples, civil society institutions, media, policymakers and the general public.
