This book offers an overview of the most important research and developments in silvopastoral systems of the northern part of South America and Central America, including the most common silvopastoral arrangements in each country and their characteristics in terms of productivity, and environmental and socioeconomic aspects. Featuring a compilation of original research articles, country overviews and reviews of the contribution of silvopastoral systems to different topics, it summarizes the state-of-the-art knowledge regarding various aspects of silvopastoral systems in this region.

This document represents a joint effort between two action networks of the Global Agenda: (i) Closing the Efficiency Gap and (ii) the Global Network on Silvopastoral Systems. A framework for evaluating natural resource use efficiency is applied to a variety of silvopastoral production models to determine productivity and their socio-economic and environmental benefits. It presents an overview of SPS, their main characteristics and advantages regarding production and benefits for the environment and climate, and their contribution to the SDGs, describing the results of ten case studies of adoption of SPS in diverse contexts in Colombia, Mexico, and Argentina, with a focus on land productivity, meat and milk production, and economic performance at the farm level. Based on the findings, a number of policy recommendations are made with a view to scaling-up and promoting SPS in Latin America and other regions.

In recent years, considerable progress has been made in the area of Nature-based Solutions (NbS) that improve ecosystem functions of environments and landscapes affected by agricultural practices and land degradation, while enhancing livelihoods and other social and cultural functions. This has opened up a portfolio of NbS options that offer a pragmatic way forward for simultaneously addressing conservation, climate and socioeconomic objectives while maintaining healthy and productive agricultural systems. NbS can mimic natural processes and build on land restoration and operational water-land management concepts that aim to simultaneously improve vegetation and water availability and quality, and raise agricultural productivity. NbS can involve conserving or rehabilitating natural ecosystems and/or the enhancement or the creation of natural processes in modified or artificial ecosystems. In agricultural landscapes, NbS can be applied for soil health, soil moisture, carbon mitigation (through soil and forestry), downstream water quality protections, biodiversity benefits as well as agricultural production and supply chains to achieve net-zero environmental impacts while achieving food and water security, and meet climate goals.

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.

Each year, billions of birds move between the forests of North America & tropical America. Many scientists are concerned with the decline of the magnificent migration systems as habitats are degraded on both ends of the flyways. The Smithsonian Migratory Bird Center is initiating a series of monographs addressing critical issues facing the conservation of migratory birds. Healthy populations of migratory birds depend upon the condition of habitats, which is in turn the result of good stewardship of the land. The SMBC will focus this series on land use & conservation issues that affect both migratory birds & the diversity of life in general. Most importantly, the SMBC recognizes that humans are an inseparable part of the habitat for migratory birds. The papers will present a synthetic, interdisciplinary approach to the biological conservation & social problems involved with the critical land use issues facing migratory bird conservation. The Series first contribution, FOREST PATCHES IN THE TROPICAL LANDSCAPE & THE CONSERVATION OF MIGRATORY BIRDS, will address the conservation of patches of native vegetation in the tropical landscape as a strategy for conserving migratory birds as well as an important component of sustainable land use.

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.
