The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.

In recent decades, practices like the cultivation of a few high-yielding crop varieties on a large scale, the application of heavy machinery and continued mechanization of agriculture, the removal of natural habitats, and the application of pesticides and synthetics have resulted in the simplification of agro-ecosystems. This has enabled a substantial increase in food production but has at the same time transformed landscapes. Indeed, there is a concern that a decline in biodiversity has affected microbiome activities that support processes across soils, plants, animals, the marine environment, and humans. Although they have increased food production, the above practices cannot be considered sustainable in long-term applications. Biodiversity, Functional Ecosystems, and Sustainable Food Production explore ecosystems in terms of crop and animal production, pest and disease control, nutrient cycling, and soil fertility. Chapters range from agro-biodiversity to antimicrobial use in animal food production to microbiome applications for sustainable food systems and the impacts of environment-friendly unit operations on the functional properties of bee pollen. By examining such topics about each other, the text emphasizes how food production, ecosystem function, food quality, and consumer health are all interconnected.

Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science. Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems. This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

between the diversity of plant and animal species and host/dependent agricultural systems. Biodiversity in Agroecosystems shows how biodiversity can be thought of not only as the rich make-up of a great number of related and competing species within an ecologically defined community, but also as the robust behavior and resilience of those species over time and as the endurance of their eco-community. This book brings to the fore new research on biodiversity in agricultural ecosystems at both micro and macro levels, heretofore available only in journals and proceedings papers.

This open access book discusses the current role of smallholders in connection with food security and poverty reduction in developing countries. It addresses the opportunities they enjoy, and the constraints they face, by analysing the availability, access to and utilization of production factors. Due to the relevance of smallholder farms, enhancing their production capacities and economic and social resilience could produce positive impacts on food security and nutrition at a number of levels. In addition to the role of small farmers as food suppliers, the book considers their role as consumers and their level of nutrition security. It investigates the link between agriculture and nutrition in order to better understand how agriculture affects human health and dietary patterns. Given the importance of smallholdings, strategies to increase their productivity are essential to improving food and nutrition security, as well as food diversity.

The Farm as Natural Habitat is a vital new contribution to the debate about agriculture and its impacts on the land. Arising from the conviction that the agricultural landscape as a whole could be restored to a healthy diversity, the book challenges the notion that the dominant agricultural landscape -- bereft of its original vegetation and wildlife and despoiled by chemical runoff -- is inevitable if we are to feed ourselves. Contributors bring together insights and practices from the fields of conservation biology, sustainable agriculture, and environmental restoration to link agriculture and biodiversity, farming and nature, in celebrating a unique alternative to conventional agriculture.Rejecting the idea that "ecological sacrifice zones" are a necessary part of feeding a hungry world, the book offers compelling examples of an alternative agriculture that can produce not only healthful food, but fully functioning ecosystems and abundant populations of native species. Contributors include Collin Bode, George Boody, Brian DeVore, Arthur (Tex) Hawkins, Buddy Huffaker, Rhonda Janke, Richard Jefferson, Nick Jordan, Cheryl Miller, Heather Robertson, Carol Shennan, Judith Soule, Beth Waterhouse, and others.The Farm as Natural Habitat is both hopeful and visionary, grounded in real examples, and guided by a commitment to healthy land and thriving communities. It is the first book to offer a viable approach to addressing the challenges of protecting and restoring biodiversity on private agricultural land and is essential reading for anyone concerned with issues of land or biodiversity conservation, farming and agriculture, ecological restoration, or the health of rural communities and landscapes.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
