Soil conservation and agroforestry. Agroforestry for control of soil erosion. Agroforestry for maintenance of soil fertility. Agroforestry for soil conservation.

Agroforestry refers to land use systems in which trees or shrubs are grown in association with agricultural crops, or pastures and livestock. From its inception, it has contained a strong element of soil management. Well-designed and managed agroforestry systems have the potential to control run-off and erosion, maintain soil organic matter and physical properties, and promote nutrient cycling. By these means, agroforestry can make a major contribution to sustainable land use. The previous edition of this book, entitled Agroforestry for Soil Conservation (1989), was based on indirect evidence from agriculture, forestry and soil science. The present work provides a new synthesis, drawing on over 700 published sources dating largely from the 1990s. These include both results of field trials of agronomy systems, and research into the plant-soil processes which take place within them. Soil conservation in its narrower sense, the control of erosion, is treated alongside other equally important aspects of soil management, such as nutrient cycling. The new edition summarizes the present state of knowledge and indicates needs for research. It is essential reading for all concerned with agroforestry, whether as students, research scientists, or for practical purposes of development. It is also of interest to soil scientists, agronomists and foresters. Anthony Young was for nine years a Principal Scientist with the International Centre for Research in Agroforestry (ICRAF), Nairobi, Kenya. He was previously Professor of Environmental Sciences at the University of East Anglia, Norwich, UK, from which he received the degree of Doctor of Science. He was a joint author of the FAO standard texts on land evaluation and land use planning. Besides these, his other books include Soil Survey and Land Evaluation (1981) and Land Resources: Now and for the Future (1998). He is now Honorary Research Fellow in Environmental Sciences at the University of East Anglia.

This book, the only one of its kind on ravine lands, reflects the significant advances made over the past two decades in our understanding of gully erosion, its controlling factors, and various aspects of gully erosion. It also addresses central research gaps and unanswered questions, which include historical studies on gully erosion to better understand the different stages of their formation; appropriate measuring techniques for monitoring or assessing the geological and hydrological parameters and processes involved in gully development; interaction of hydrological and other soil degradation processes; ecology and biodiversity of fragile ravines; impact of climate and environmental changes on soil erosion processes; development of effective and reliable gully erosion models; effective gully prevention and control measures; watershed-based management options; and ravine rehabilitation policies. The present book is a highly timely publication and deals with various aspects of ravine ecology and rehabilitation of degraded lands, particularly with the aid of biological approaches. As such, it offers a valuable guide for all scientists working in the fields of soil conservation / rehabilitation and agroforestry, students, environmentalists, educationists, and policymakers. More importantly, it focuses on the rehabilitation of one of the world’s most degraded and fragile ecosystems, ensuring the livelihoods of resource-poor farmers and landless families living in harsh ecologies that are more vulnerable to climate change.

Agroforestry for Carbon and Ecosystem Management is a comprehensive overview of current research, issues, challenges, and case studies in the area of agroforestry. It focuses specifically on carbon source-sink relationship and management through agroforestry practices with the goal of improving overall environmental sustainability. Through expert insights and case studies, the book promotes carbon management, greenhouse gas emission reduction, forest, and ecosystem services management along with relevant sustainable approaches for natural resources conservation. It provides insight into novel approaches for natural resource management, with specific attention given to technologies related to carbon capture and management. Agroforestry for Carbon and Ecosystem Management also proposes possible polices and plans for future research and implementation, the latest updates in the area of agroforestry research for sustainability, developments in carbon dynamics and management, addresses the knowledge gap in relation to agroforestry, sustainability and agroecosystem management and explores the application of remote sensing and geospatial technology for agroforestry management. Presents the latest insights in agroforestry and ecosystem management to achieve Sustainable Development Goals (SDGS) for a green future Includes both theoretical and practical approaches to agroforestry practices Presents expert insights on the multidisciplinary challenges and opportunities of agroforestry for carbon and other ecological impacts Explores the integration of technological interfaces for improving the potential of agroforestry practices
