The conservation of biodiversity has profound implications for managing natural resources with the need for scientific information as a foundation for management decisions increasing dramatically. The_ intent of this book is to look beyond the theory of biodiversity to_ the principles, practices, and policies needed for its conservation. Its objectives are to provide the scientific basis for understanding biodiversity, document case examples of theory and concepts applied at differing scales, and examine policies that affect its conservation.

Describes how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. Includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels.

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 study presents authentic data compiled from field experiments and investigations, and provides a point of reference for any future changes associated with anthropogenic activity in semiarid ecosystems. Three years of continuous and rigorous empirical research on biodiversity (from phytoplankton to higher plants and from zooplankton to higher animals – all flora and fauna) in India’s semiarid region have culminated in this work. Though there are many studies available on issues related to biodiversity, the majority cover either specific groups of plants or groups of animals; with the exception of this book, studies that include all flora and fauna including the phyto- and zooplanktons in a given ecosystem are not readily available. Further, the book focuses on an extremely important topic, firstly because semiarid landscapes are highly vulnerable to climate change, and secondly because other developmental activities will be undertaken in the region in an effort to meet its energy requirements. As such, the results of the current study will provide a standard protocol for subsequent monitoring and mapping of biodiversity for conservation and management. The book explores, quantifies and surveys plant and animal species from aquatic and terrestrial ecosystems, assessing and quantitatively analyzing the diversity indices of different vegetation strata. Further, it investigates the conservation status of each species (flora and fauna) in keeping with IUCN categories. The study also examines landscape dynamics using RS and GIS for vegetation analysis, and discusses traditional ecological knowledge related to the use, conservation and management of biodiversity. As such, it offers a unique and valuable resource not only for researchers from the environmental/ecological sciences but also for conservationists and policymakers.

Discusses the ways in which we can continue to benefit from forests, while conserving their biodiversity.

Explains why it is important to sustain native plants & animals in agricultural landscapes, outlines issues in developing & implementing practical approaches to safeguard native biodiversity in rural areas. Considers ecological & agricultural issues that determine what native biodiversity occurs in farmland.--

CONSERVATION BIOGEOGRAPHY The Earth’s ecosystems are in the midst of an unprecedented period of change as a result of human action. Many habitats have been completely destroyed or divided into tiny fragments, others have been transformed through the introduction of new species, or the extinction of native plants and animals, while anthropogenic climate change now threatens to completely redraw the geographic map of life on this planet. The urgent need to understand and prescribe solutions to this complicated and interlinked set of pressing conservation issues has lead to the transformation of the venerable academic discipline of biogeography – the study of the geographic distribution of animals and plants. The newly emerged sub-discipline of conservation biogeography uses the conceptual tools and methods of biogeography to address real world conservation problems and to provide predictions about the fate of key species and ecosystems over the next century. This book provides the first comprehensive review of the field in a series of closely interlinked chapters addressing the central issues within this exciting and important subject.
