Opportunities and Challenges for Sustainable Production and Marketing of Gums and Resins in Ethiopia
This publication is intended to serve researchers and teachers as well as development practitioners. It was prepared based on requests from CIFORs national partners in Ethiopia and the region to compile existing information and help address the lack of documents available for teaching graduate and undergraduate students about the management of forests in dryland areas in general, and the production and marketing of gums and resins in particular.
State of the Art in Ethiopian Church Forests and Restoration Options
This book, with contributions from leading academics - and including reviews and case studies from Ethiopian Church forests - provides a valuable reference for advanced students and researchers interested in forest and other natural resource management, ecology and ecosystem services as well as restoration options. The book addresses various aspects including a general overview of Ethiopian church forests, the present role and future challenges of church forests. It also discusses their structure and diversity in the context of sustainability and discusses restoration options for surrounding landscapes, under consideration of the circumstances of the land and the needs of surrounding communities. The intended readership includes natural resource professionals in general as well as forestry professionals in particular (practitioners, policymakers, educators and researchers). The book will provide the reader with a good foundation for understanding Ethiopian forest resources and restoration options of degraded landscape.
Management guide for sustainable production of frankincense
This guide is intended for frankincense producers, extension workers and companies engaged in producing frankincense. Gum olibanum (frankincense) from Boswellia papyrifera (Del.) Hochst has been collected and traded for centuries. Although production levels in Ethiopia fall far short of the countrys potential, export volume and earnings from frankincense have been significantly increasing since the late 1990s. But knowledge regarding the biology and ecophysiology of the tree, the frankincense collecting process and post-harvest handling remain largely inadequate.
Degraded Forests in Eastern Africa
Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.
Silviculture in the Tropics
This book integrates the latest global developments in forestry science and practice and their relevance for the sustainable management of tropical forests. The influence of social dimensions on the development of silvicultural concepts is another spotlight. Ecology and silvicultural options form all tropical continents, and forest formations from dry to moist forests and from lowland to mountain forests are covered. Review chapters which guide readers through this complex subject integrate numerous illustrative and quantitative case studies by experts from all over the world. On the basis of a cross-sectional evaluation of the case studies presented, the authors put forward possible silvicultural contributions towards sustainability in a changing world. The book is addressed to a broad readership from forestry and environmental disciplines.
Scent
A fascinating exploration of the natural history of scent and human perceptions of fragrance from the viewpoint of plant and pollinator Plants have long harnessed the chemical characteristics of aromatic compounds to shape the world around them. Frankincense resin from the genus Boswellia seals injured tissues and protects trees from invading pathogens. Jasmine produces a molecule called linalool that attracts pollinating moths with its flowery scent. Tobacco uses a similarly sweet-smelling compound called benzyl acetone to attract pollinators. Only recently in the evolutionary history of plants, however, have humans learned to co-opt their fragrances to seduce, heal, protect, and alter moods themselves. In this wide-ranging and accessible new book, biologist-turned-perfumer Elise Vernon Pearlstine turns our human-centered perception of fragrance on its head and investigates plants' evolutionary reasons for creating aromatic molecules. Delving into themes of spirituality, wealth, power, addiction, royalty, fantasy, and more, Pearlstine uncovers the natural history of aromatic substances and their intersection with human culture and civilization.
Agro-Ecological Intensification of Agricultural Systems in the African Highlands
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four th...
