Agroforestry systems are believed to provide a number of ecosystem services; however, until recently evidence in the agroforestry literature supporting these perceived benefits has been lacking. This volume brings together a series of papers from around the globe to address recent findings on the ecosystem services and environmental benefits provided by agroforestry. Specifically, this volume examines four major ecosystem services and environmental benefits: (1) carbon sequestration, (2) biodiversity conservation, (3) soil enrichment and (4) air and water quality. Past and present evidence clearly indicates that agroforestry, as part of a multifunctional working landscape, can be a viable land-use option that, in addition to alleviating poverty, offers a number of ecosystem services and environmental benefits. This realization should help promote agroforestry and its role as an integral part of a multifunctional working landscape the world over. The book should be particularly useful to students, professionals, researchers and policy makers involved in natural resource management, agroforestry, biodiversity conservation, and environmental management.

Agricultural systems are no longer evaluated solely on the basis of the food they provide, but also on their capacity to limit impacts on the environment, such as soil conservation, water quality and biodiversity conservation, as well as their contribution to mitigating and adapting to climate change. In order to cope with these multiple service functions, they must internalize the costs and benefits of their environmental impact. Payments for ecosystem services are hoped to encourage and promote sustainable practices via financial incentives. The authors show that while the principle is straightforward, the practice is much more complicated. Whereas scenic beauty and protection of water sources provide benefits to the local population, carbon sequestration and biodiversity conservation can be considered international public goods, rendering potential payment schemes more complex. Few examples exist where national or international bodies have been able to set up viable mechanisms that compensate agricultural systems for the environmental services they provide. However this book provides several examples of successful programs, and aims to transfer them to other regions of the world. The authors show that a product can be sold if it is clearly quantified, there exists a means to determine the service's values, and there is a willing buyer. The first two sections of the book present methodological issues related to the quantification and marketing of ecosystem services from agriculture, including agroforestry. The third and final section presents case studies of practical payments for ecosystem services and experiences in Central and South America, and draws some lessons learnt for effective and sustainable development of ecosystem services compensation mechanisms.

As a dynamic interface between agriculture and forestry, agroforestry has only recently been formally recognized as a relevant part of land use with 'trees outside forest' in important parts of the world--but not everywhere yet. The Sustainable Development Goals have called attention to the need for the multifunctionality of landscapes that simultaneously contribute to multiple goals. In the UN decade of landscape restoration, as well as in response to the climate change urgency and biodiversity extinction crisis, an increase in global tree cover is widely seen as desirable, but its management by farmers or forest managers remains contested. Agroforestry research relates tree-soil-crop-livestock interactions at the plot level with landscape-level analysis of social-ecological systems and efforts to transcend the historical dichotomy between forest and agriculture as separate policy domains. An 'ecosystem services' perspective quantifies land productivity, flows of water, net greenhouse gas emissions, and biodiversity conservation, and combines an 'actor' perspective (farmer, landscape manager) with that of 'downstream' stakeholders (in the same watershed, ecologically conscious consumers elsewhere, global citizens) and higher-level regulators designing land-use policies and spatial zoning.

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.

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

Ecosystem services are the resources and processes supplied by natural ecosystems which benefit humankind (for example, pollination of crops by insects, or water filtration by wetlands). They underpin life on earth, provide major inputs to many economic sectors and support our lifestyles. Agricultural and urban areas are by far the largest users of ecosystems and their services and (for the first time) this book explores the role that ecosystem services play in these managed environments. The book also explores methods of evaluating ecosystem services, and discusses how these services can be maintained and enhanced in our farmlands and cities. This book will be useful to students and researchers from a variety of fields, including applied ecology, environmental economics, agriculture and forestry, and also to local and regional planners and policy makers.

Agroforestry is a type of land management system where trees or shrubs are planted around or surrounding the crops or pastureland. Such type of land management helps in producing a variety of products such as fruits, wood products, pharmaceuticals and other valuable products that can be traded commercially. It ensures long-term sustainability of agriculture. Some of its other benefits include improved farmer livelihoods through wealth creation, higher yields from staple food crops, carbon sequestration, increased biodiversity, and enhanced soil structure and health. Agroforestry helps blend forestry and farming, which helps restore the land by reducing soil erosion and regulating the water accessibility to restore the land. The practice of agroforestry leads to ecosystem services, which refers to the human benefits apart from an increase in farm produce. Agroforestry-based ecosystem services help in improving agricultural sustainability by ensuring better usage of fertilizers, enhanced ground cover, improved insect resistance, and weed avoidance. This book elucidates the concepts and innovative models around prospective developments with respect to agroforestry-based ecosystem services and environmental benefits of agroforestry. It will also provide interesting topics for research, which interested readers can take up.

Agroforestry systems (AFS) are becoming increasingly relevant worldwide as society has come to recognize their multiple roles and services: biodiversity conservation, carbon sequestration, adaptation and mitigation of climate change, restoration of degraded ecosystems, and tools for rural development. This book summarizes advances in agroforestry research and practice and raises questions as to the effectiveness of AFS to solve the development and environmental challenges the world presents us today. Currently AFS are considered to be a land use that can achieve a compromise among productive and environmental functions. Apparently, AFS can play a significant role in rural development even in the most challenging socioeconomic and ecological conditions, but still there is a lot of work to do to reach these goals. Considerable funding is spent in projects directed to enhancing productivity and sustainability of smallholders forestry and agroforestry practices. These projects and programs face many questions and challenges related to the integration of traditional knowledge to promote the most suitable systems for each situation; access to markets for AFS products, and scaling up of successful AFS. These complex questions need innovative approaches from varying perspectives and knowledge bases. This book gathers fresh and novel contributions from a set of Yale University researchers and associates who intend to provide alternative and sometimes departing insights into these pressing questions. The book focuses on the functions that AFS can provide when well designed and implemented: their role in rural development as they can improve food security and sovereignty and contribute to provision of energy needs to the smallholders; and their environmental functions: contribution to biodiversity conservation, to increased connectivity of fragmented landscapes, and adaptation and mitigation of climate change. The chapters present conceptual aspects and case studies ranging from traditional to more modern approaches, from tropical as well as from temperate regions of the world, with examples of the AFS functions mentioned above.

This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.
