Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.

This book employs a political ecology lens to unravel how industrial crops catalyse ecological, agrarian, socioeconomic, and institutional transformation. Using the conceptual tools and perspectives of political ecology, namely multi-scalar analysis and attention to marginalisation, social difference, and discourses and narratives, this volume provides a critical and comprehensive assessment of the transformative power of industrial cropping systems. It presents a truly international overview by drawing on a range of case studies from the global South, including soybeans in South America, cashew nuts in Guinea Bissau, cotton in India, maize in China, jatropha in Ghana, sugarcane in Peru and Eswatini, and oil palm in Ghana and Peru. The unique case studies are put into perspective with chapters introducing the key concepts of political ecology and critical dimensions of industrial cropping systems related to large-scale land acquisitions, land grabbing, and marginal land. The individual chapters employ different approaches all rooted in political ecology, thus offering a rich overview of how the field engages with such cropping systems. Overall, this volume contains valuable propositions for improving current policies and practices in industrial crop settings in both developed and developing countries. Through its comprehensive and interdisciplinary outlook, this volume will be of great interest to students and scholars of political ecology, agrarian studies, development studies, and ecological economics.

Based on twenty years of global research, this is the first comprehensive reference on crop genetic diversity as it is maintained on farmland around the world. Showcasing the findings of seven experts representing the fields of ecology, crop breeding, genetics, anthropology, economics, and policy, this invaluable resource places farmer-managed crop biodiversity squarely in the center of the science needed to feed the world and restore health to our productive landscapes. It will prove to be an essential tool in the training of agricultural and environmental scientists seeking the solutions necessary to ensure healthy, resilient ecosystems for future generations.

Agricultural crops are prominent features of an increasing number of variously perturbed ecosystems and the landscapes occupied by these ecosystems. Yet the ecology of agricultural-dominated landscapes is only now receiving the scientific attention it has long deserved. This attention has been stimulated by the realization that all agriculture must become sustainable year after year while leaving nearby ecosystems unaffected. Ecology in Agriculture focuses exclusively on the ecology of agricultural ecosystems. The book is divided into four major sections. An introduction establishes the unique ties between agricultural and ecological sciences. The second section describes the community ecology of these sorts of ecosystems, while the final section focuses on the processes that operate throughout these agricultural landscapes. Contains an ecological perspective on agricultural production and resource utilization Includes in-depth reviews of major issues in crop ecology by active researchers Covers a range of topics in agricultural ecophysiology, community ecology, and ecosystems ecology Provides examples of ecological approaches to solving problems in crop management and environmental quality

The growing of crops for bioenergy has been subject to much recent criticism, as taking away land which could be used for food production or biodiversity conservation. This book challenges some commonly-held ideas about biofuels, bioenergy and energy cropping, particularly that energy crops pose an inherent threat to ecosystems, which must be mitigated. The book recognises that certain energy crops (e.g. oil palm for biodiesel) have generated sustainability concerns, but also asks the question "is there a better way?" of using energy crops to strategically enhance ecosystem functions. It draws on numerous case studies, including where energy crops have had negative outcomes as well as well as cases where energy crops have produced benefits for ecosystem health, such as soil and water protection from the cropping of willow and poplar in Europe and the use of mallee eucalypts to fight salinity in Western Australia. While exploring this central argument, the volume also provides a systematic overview of the socio-economic sustainability issues surrounding bioenergy.

This book critically examines the idea that the sustainability of agriculture could be improved by mimicking the structure and processes occurring in natural ecosystems. Researchers from around the world present comparative studies of multi-species farming systems, natural ecosystems and conventional agriculture. Case studies from Europe, Africa, Asia, Australia, and North and South America examine the implications of increasing the complexity of farming systems on water and nutrient cycling, productivity and resilience. Theoretical issues discussed include the role of biodiversity in agriculture, the trade-off between perenniality and productivity, the choice to integrate or segregate production and conservation in an agricultural landscape, and the social and economic challenges to adopting complex farming systems. One section is devoted to the application of this concept in southern Australia, where 15 million hectares of land are expected to be affected by salinity by the middle of the next century unless there is a significant change in agricultural practice.
