This book was released on 2010-02-04 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: not only for land use systems that depend on the regular supply of rain or irrigation water but also for the future development of natural rainforests as drought stress has been shown to a?ect tree growth and species composition in old-growth forests (Wright 1991, Walsh and Newbery 1999, Engelbrecht et al. 2007). A drought experiment conducted in a cacao agroforestry plantation showed that this plantation was surprisingly resilient to an induced drought of more than a year (Schwendenmann et al. 2009). However, droughts can have a strong impact on household incomes from agriculture, they strongly a?ect the vulnerability to poverty and thus have to be analyzed as important exogenous shocks to households, forcing them to adjust their behaviour and develop strategies to cope with these problems. The stability of rainforest margins is a critical factor in the protection of tropical rainforests (Tscharntke et al. 2007). At present, however, rainf- est margins in many parts of the tropics are far from stable, both in soc- economic and in ecological terms. For example, protected areas may attract, rather than repel, human settlement, which may be due to international donor investment in national conservation programs (Wittemeyer et al. 2008). An alternative hypothesis is that protected areas might be compromised if leakage takes place, that is, if impacts that would take place inside the restricted area are displaced to a nearby, undisturbed area (Ewers and Rodrigues 2008).

This book was released on 1992 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of the workshop was on policy and economic issues associated with developing alternativas to slash-and-burn agriculture, since that form of land use is a major cause of tropical deforestation. Particular emphasis is given to the distribution and growth of populations in tropical forest areas, to the effects of shortnend fallow periods, and to opportunities for addressing policy research needs in these areas.
Download or read book Carbon Sequestration Potential of Agroforestry Systems written by B. Mohan Kumar and published by Springer Science & Business Media. This book was released on 2011-08-05 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree based production systems abound especially in the tropics. Despite the pervasiveness of such multipurpose “trees-outside-forest” resources, they have not attracted adequate attention in the development paradigms of many nation states. These multispecies production systems impact the ecosystem processes favourably. Yet, our understanding of the diversity attributes and carbon dynamics under agroforestry is not adequate. This book focuses on the role of multispecies production systems involving tree and crop species as a means for carbon sequestration and thereby reduce atmospheric carbon dioxide levels. Sixteen chapters organized into three broad sections titled: Measurement and Estimation, Agrobiodiversity and Tree Management, and Policy and Socioeconomic Aspects represent a cross section of the opportunities and challenges in current research and emerging issues in harnessing carbon sequestration potential of agroforestry systems.

Book excerpt: Agroforestry is an approach to alternative land use based on deliberate integration of trees with crops and livestock production systems. It combines agricultural and forestry technologies to create more diverse, productive, profitable, healthy and sustainable land-use systems. Agroforestry can include various types of practices, including alley cropping, forest farming, shelterbelts (or timberbelts), riparian buffer strips, and silvopastoral systems. In arid and semi-arid environments, agroforestry systems potentially support livelihood improvement through simultaneous production of food, fodder and firewood without much affecting climate change. Careful selection of species and good management of trees and crops are needed to optimise the production and positive effects within the system and to minimise negative competitive effects. This book gathers the latest research from around the globe in the study of agroforestry and highlights such topics as traditional and modern agroforestry in Mediterranean regions, integration of native genetic resources in agroforestry, women agroforestry practices in refugee settlements, a discussion of the major obstacles that prevent increased agroforestry improvements, and the advantages and constrains of agroforestry systems establishment in various Brazilian biomes.

Download or read book Agroforestry Systems in the Tropics written by P.K. Nair and published by Springer. This book was released on 2011-10-12 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consolidates the descriptive results of a pantropical project called Agroforestry Systems Inventory (AFSI), undertaken by the International Council for Research in Agroforestry (ICRAF) from 1982 to 1987. Since agroforestry was a relatively new term when the project was initiated, the main objective was to increase the understanding of and provide a state-of the-art information base on existing agroforestry systems. Therefore, the project was designed to systematically collect, collate, synthesize, and dissem inate information on existing agroforestry systems in developing countries. One of the major results of the project, descriptions of existing agroforestry systems, was published as a series of articles in Agroforestry Systems. These system descriptions form the bulk of this book. Other products of the project include a microcomputer database on agroforestry systems, practices and components, and voluminous unpublished reports and records. Perhaps the title of the book is misleading in that the book does not include or cover all existing agroforestry systems in the tropics and geographical regions in the tropics. Additionally, some of the systems described are outside the tropical boul;ldaries of 23. 5" Nand S latitudes. For the purpose of this book, the word tropics is used in a general sense to also include subtropical developing countries that have agro-ecological and socio-economic character istics and land-use problems similar to those of the countries within the geographical limits of the tropical belt.

Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.
