In a world increasingly challenged by the need to integrate and understand highly specialized knowledge in a multidisciplinary way, this book is innovative and perhaps unique in addressing this challenge. It focuses on ideas, strategies, techniques and practices spanning many disciplines at the interface of agriculture with: forestry, horticulture, plant physiology, genetics, ecology, soil science, food science, economics, and the social and environmental sciences as delivered by intensified and enriched agroforestry. Multifunctional Agriculture addresses this complexity, using case studies and insights from the needs of African farmers whose livelihoods are constrained by complex interactions between social, environmental and economic factors and problems underlying agricultural sustainability in Africa. This book, therefore, provides an important resource for those trying to understand the role of agriculture in the achievement of the new Sustainable Development Goals by providing easily implementable, practical and effective methodologies and practices.

It has been recognized that an important factor in improving the viability of rural livelihoods in developing countries is the promotion of sustainable agriculture. As opposed to relying solely on cash crops, this can be more easily achieved through the domestication of various indigenous fruit trees that can be cultivated and owned by smallholder farmers. Through multi-functional and integrated farming systems, these tree crops can support environmental and social sustainability by providing food as well as promoting economic growth. Twenty years ago, little was known about the biology, ecology or the social impact of indigenous fruit trees on rural populations. Since then, new concepts and approaches have been developed, case studies have been produced and the potential and feasibility of their domestication and commercialization has been explored. This focused study on the tropics brings together a comprehensive review of this research.
