[EBOOK] Managing Biodiversity in Agricultural Ecosystems, Edited by D. I. Jarvis et al., Published by Bioversity International and Columbia University Press New York

Biodiversity in agricultural ecosystems provides our food and the means to produce it. The variety of plants and animals that constitute the food we eat are obvious parts of agricultural biodiversity. Less visible—but equally important—are the myriad of soil organisms, pollinators, and natural enemies of pests and diseases that provide essential regulating ser vices that support agricultural production. Every day, farmers are managing these and other aspects of biological diversity in agricultural ecosystems in order to produce food and other products and to sustain their livelihoods. Biodiversity in agricultural ecosystems also contributes to generating other ecosystem ser vices such as watershed protection and carbon sequestration. Besides having this functional signifi cance, maintenance of biodiversity in agricultural ecosystems may be considered important in its own right. Indeed, the extent of agriculture is now so large, any strategy for biodiversity conservation must address biodiversity in these largely anthropogenic systems. Moreover, biodiversity in agricultural landscapes has powerful cultural signifi cance, partly because of the interplay with historic landscapes associated with agriculture, and partly because many people come into contact with wild biodiversity in and around farmland.

This book examines these various aspects of agricultural biodiversity. A number of chapters examine crop ge ne tic resources (chapters 1, 2, 3, 10, 11, and 16) and livestock ge ne tic resources (chapters 4, 5, and 17). Other chapters examine aquatic biodiversity (chapter 6), pollinator diversity (chapter 7), and soil biodiversity (chapter 8). Three chapters (9, 10, and 11) examine various aspects of the relationship between diversity and the management of pests and diseases. Chapters 12 and 13 explore farmer management of diversity in the wider context of spatial complexity and environmental and economic change. Chapter 14 looks at the contribution of diversity to diet, nutrition, and human health. Chapters 15 through 17 explore the value of ge ne tic resources and of the ecosystem ser vices provided by biodiversity in agricultural ecosystems.

This introductory chapter sets the scene for the subsequent chapters. After reviewing recent efforts to address agricultural biodiversity in the academic community and international policy fora, the multiple dimensions of biodiversity in agricultural ecosystems are surveyed. Subsequent sections examine the value of ecosystems ser vices provided by biodiversity, the functions of biodiversity, and how these are infl uenced by management. The chapter concludes with a brief consideration of the future of biodiversity in agricultural ecosystems.
