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.

This book is a state-of-the-art compilation of the latest information on ecosystem services of agroforestry. The last two decades have seen a surge in literature on the ecosystem services of sustainable agriculture practices, including that of agroforestry; however, compilation and synthesis of such information from agroforestry have been limited. This book fills that void by bringing in a number of experts from around the world. In addition to presenting the multiple dimensions of ecosystem services provided by major agroforestry practices, the book also offers case studies from both tropical and temperate regions of the world. Information from this book can be used to design land management practices for climate change mitigation, ecosystem benefits, agricultural productivity and sustainability, and for survival and profitability of family farms and to conserve biodiversity. While synthesizing information of the biophysical aspects of ecosystem services, the book also outlines the socioeconomic and policy dimensions, including appropriate incentive models to enhance adoption of agroforestry so that society at large can enjoy these important benefits

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.

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

This college-level textbook summarizes the state of current knowledge in the rapidly expanding field of agroforestry. The book, organized into 25 chapters in six sections, reviews the developments in agroforestry during the past 15 years and describes the accomplishments in the application of biophysical (plant and soil related) and socioeconomic sciences to agroforestry. Although the major focus of the book is on the tropics, where the practice and potential of agroforestry are particularly promising, the developments in temperate zone agroforestry are also discussed. This text is recommended for students, teachers, and researchers in agroforestry, farming systems, and tropical land use.

Agroforestry is an age old practice throughout the world, but its recognition as a science is nearly three decades old. The scientific and systematic research on tree-crop interactions, in India, started in late 1970's and got major support and impetus with the establishment of All India Coordinated Research Project (AICRP) on Agroforestry in 1983 by ICAR. Today AICRP on Agroforestry has its network through out the country. Under AICRP and through the individual efforts of State Agricultural Universities, location specific agroforestry systems has been recommended to suit agro-climatic zones, landholdings and economic status of the region. Though extensive research had been done till date, but it is not available to scientific world, farming communities (who are the backbone of Indian rural development), students and inquisitive readers in one manuscript. This prompted the authors to club the information on agroforestry systems and practices prevailing in India in form of book. For the sake of convenience, agroforestry systems prevailing in India have been divided into four broad sections i) Agroforestry in India ii) Agroforestry system and practices in North, West and Central India iii) Agroforestry systems and practices in East, North-East and Southern India iv) Allied topics related to Agroforestry. Section one cover topics covering agroforestry experiences, research and extension efforts done in the last 25 years in India. Section two includes 13 chapters and section three covers 14 chapters wherein agroforestry research vis-à-vis agroclimatic zones of different states of India have been discussed. The last section comprising of 8 chapters includes topics related to role of agroforestry in soil conservation, women development; management of agroforestry; modeling; rehabilitation of mine spoils and breeding of agroforestry tree species.

Agroforestry -- the practice of integrating trees and other large woody perennials on farms and throughout the agricultural landscape -- is increasingly recognized as a useful and promising strategy that diversifies production for greater social, economic, and environmental benefits. Agroforestry and BiodiversityConservation in Tropical Landscapes brings together 46 scientists and practitioners from 13 countries with decades of field experience in tropical regions to explore how agroforestry practices can help promote biodiversity conservation in human-dominated landscapes, to synthesize the current state of knowledge in the field, and to identify areas where further research is needed. Agroforestry and Biodiversity Conservation in Tropical Landscapes is the first comprehensive synthesis of the role of agroforestry systems in conserving biodiversity in tropical landscapes, and contains in-depth review chapters of most agroforestry systems, with examples from many different countries. It is a valuable source of information for scientists, researchers, professors, and students in the fields of conservation biology, resource management, tropical ecology, rural development, agroforestry, and agroecology.
