Book Description
Habitat loss and fragmentation arguably pose the greatest threats to biological diversity. Agriculture is a dominant land use that, along with urban sprawl and residential development, can reduce the amount and connectedness of natural areas required by many native species. Unfortunately, progress has been slow in integrating nature and biodiversity protection into community planning in intensively farmed regions, especially in America's heartland. Seldom do issues related to species conservation receive consideration during local planning activities. Lack of progress stems partly from scientific inadequacies in understanding the dynamics of complex landscapes, and from a lack of engagement of non-scientific stakeholders by scientists and modelers. The result of these shortcomings is a critical disconnect of conservation issues from the planning infrastructure. This book provides a blueprint for advancing conceptual understanding of conservation in agricultural regions. It accomplishes this with a two-pronged approach: first, by developing spatially structured models that acknowledge the link between socio-economic drivers of land-use change and the dynamics of species occupying agricultural landscapes with abrupt changes in land cover (i.e., sharp edges); and second, by providing guidelines and examples to enable scientists to effectively engage stakeholders in participatory learning and planning activities that integrate biodiversity with other, more traditional, considerations. The structure of the book is truly interdisciplinary, linking the efforts of ecologists, economists, statisticians, mathematicians, and land-use specialists.

Book Description
With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

Book Description
North and South America share similar human and ecological histories and, increasingly, economic and social linkages. As such, issues of ecosystem functions and disruptions form a common thread among these cultures. This volume synthesizes the perspectives of several disciplines, such as ecology, anthropology, economy, and conservation biology. The chief goal is to gain an understanding of how human and ecological processes interact to affect ecosystem functions and species in the Americas. Throughout the text the emphasis is placed on habitat fragmentation. At the same time, the book provides an overview of current theory, methods, and approaches used in the analysis of ecosystem disruptions and fragmentation.

Book Description
Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.

Book Description
There can be little doubt that there are truly colossal challenges associated with providing food, fibre and energy for an expanding world population without further accelerating already rapid rates of biodiversity loss and undermining the ecosystem processes on which we all depend. These challenges are further complicated by rapid changes in climate and its additional direct impacts on agriculture, biodiversity and ecological processes. There are many different viewpoints about the best way to deal with the myriad issues associated with land use intensification and this book canvasses a number of these from different parts of the tropical and temperate world. Chapters focus on whether science can suggest new and improved approaches to reducing the conflict between productive land use and biodiversity conservation. Who should read this book? Policy makers in regional, state and federal governments, as well as scientists and the interested lay public.

Book Description
The Handbook provides a supporting guide to key aspects and applications of landscape ecology to underpin its research and teaching. A wide range of contributions written by expert researchers in the field summarize the latest knowledge on landscape ecology theory and concepts, landscape processes, methods and tools, and emerging frontiers. Landscape ecology is an interdisciplinary and holistic discipline, and this is reflected in the chapters contained in this Handbook. Authors from varying disciplinary backgrounds tackle key concepts such as landscape structure and function, scale and connectivity; landscape processes such as disturbance, flows, and fragmentation; methods such as remote sensing and mapping, fieldwork, pattern analysis, modelling, and participation and engagement in landscape planning; and emerging frontiers such as ecosystem services, landscape approaches to biodiversity conservation, and climate change. Each chapter provides a blend of the latest scientific understanding of its focal topics along with considerations and examples of their application from around the world. An invaluable guide to the concepts, methods, and applications of landscape ecology, this book will be an important reference text for a wide range of students and academics in ecology, geography, biology, and interdisciplinary environmental studies.

Book Description
Agricultural expansion has transformed and fragmented forest habitats at alarming rates across the globe, but particularly so in tropical landscapes. The resulting land-use configurations encompass varying mosaics of tree cover, human settlements and agricultural land units. Meanwhile, global demand for agricultural commodities is at unprecedented levels. The need to feed nine billion people by 2050 in a world of changing food demands is causing increasing agricultural intensification. As such, market-orientated production systems are now increasingly replacing traditional farming practices, but at what cost? The Agrarian Change project, coordinated by the Center for International Forestry Research, explores the conservation, livelihood and food security implications of land-use and agrarian change processes at the landscape scale. This book provides detailed background information on seven multi-functional landscapes in Ethiopia, Cameroon, Indonesia, Nicaragua, Bangladesh, Zambia and Burkina Faso. The focal landscapes were selected as they exhibit various scenarios of changing forest cover, agricultural modification and integration with local and global commodity markets. A standardized research protocol will allow for future comparative analyses between these sites. Each case study chapter provides a comprehensive description of the physical and socioeconomic context of each focal landscape and a structured account of the historical and political drivers of land-use change occurring in the area. Each case study also draws on contemporary information obtained from key informant interviews, focus group discussions and preliminary data collection regarding key topics of interest including: changes in forest cover and dependency on forest products, farming practices, tenure institutions, the role and presence of conservation initiatives, and major economic activities. The follow-on empirical study is already underway in the landscapes described in this book. It examines responses to agrarian change processes at household, farm, village and landscape levels with a focus on poverty levels, food security, dietary diversity and nutrition, agricultural yields, biodiversity, migration and land tenure. This research intends to provide much needed insights into how landscape-scale land-use trajectories manifest in local communities and advance understanding of multi-functional landscapes as socioecological systems.
