Diversification of products and services from diverse on-farm trees allowed the traditional agroforestry systems of southern Ethiopia to be considered as sustainable farming systems over a timescale of centuries. But their sustainability has been threatened in recent years, owing to the increasing pressure from a rapidly growing population. Investigation of the diverse tree species on agroforestry for various products and services is beneficial to explore the relationships of some farm characteristics with tree species diversity. Very little academic literatures exist on the agroforestry systems of on-farm tree species diversity. This book, therefore provides a new findings on the characterization of tree species diversity, how the diversity of trees and shrub species are linked to farm characteristics and composition of tree species under agroforestry land use system. It also provides new ideas on the importance value index and use-diversity of different tree species. A complete inventory of on-farm tree species and farm characteristics is analyzed. The analysis should give some knowledge and should be primarily useful to professionals in fields of agroforsetry and agriculture.
‘Homegardens’ are integrated tree–crop–animal production systems, often established on small parcels of land surrounding homesteads, and primarily found in tropical environments. This multi-authored volume contains peer-reviewed chapters from the world’s leading researchers and professionals in this topic. It summarizes the current state of knowledge on homegarden systems, with a view to using this knowledge as a basis for improving both homegardens and other similar multistrata agroforestry systems.
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.
Describes how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. Includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels.
Master's Thesis from the year 2019 in the subject Agrarian Studies, , language: English, abstract: The plant species diversity and socio-economic contributions of agroforestry practices have not well known in Lay Armachiho Woreda. Therefore, this study was conducted with the objective of assessing environmental and socio-economic contribution of agroforestry practices in Lay Armachiho Woreda. The basic data employed in this study were obtained from three randomly selected kebele from 29 rural kebele and 183 randomly selected sample households from 1905 households. A simple random sampling procedure was employed to select the sample farm household heads. The data that was gathered using a semi structured questioner were analyzed using descriptive statistics Focus group discussions, Field observation, and key informants interviews were analyzed using content analysis Ground survey were analyzed using Shannon diversity index and Simpson diversity index.
Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.
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.
