Presenting new approaches to studying food webs, this book uses practical management and policy examples to demonstrate the theory behind ecosystem management decisions and the broader issue of sustainability. All the information that readers need to use food web analyses as a tool for understanding and quantifying transition processes is provided. Advancing the idea of food webs as complex adaptive systems, readers are challenged to rethink how changes in environmental conditions affect these systems. Beginning with the current state of thinking about community organisation, complexity and stability, the book moves on to focus on the traits of organisms, the adaptive nature of communities and their impacts on ecosystem function. The final section of the book addresses the applications to management and sustainability. By helping to understand the complexities of multispecies networks, this book provides insights into the evolution of organisms and the fate of ecosystems in a changing world.

'Axel Linden is a shepherd-philosopher with James Herriot's knack for mishap and an almost Chekhovian deadpan humour.' Observer 'Endearing and liberating.' Idler Magazine 'A sublime little book.' Cotswold Life _______ Why do we keep sheep? Alex Linden ruminates as he watches his sheep ruminating. Naive and inexperienced, he has ditched his doctoral studies in order to move to a fully working farm in the country with his family, where he is tasked with the responsibility of caring for a herd of sheep. Linden records his new life in his diary, as he tries to manage life on the farm, the ever-escaping sheep and the trials and tribulations that come with being a shepherd - shearing, lambing and confronting the slaughterhouse. As time passes and he gradually settles into the rhythm of shepherding, his naivete fades away and is replaced with stark realisations about what is now his everyday life. He finds himself applying his experiences of animal husbandry to consider our place - as individuals and as a collective organism - in the universe. Is he really the one caring for the sheep, or are they the ones keeping him? Linden finds both companionship in his flock and a sound, if complex, moral framework for examining the lives we lead. The result is a sensitive and entertaining meditation on the small wonders in our world.

Carbon is the political challenge of our time. While critical to supporting life on Earth, too much carbon threatens to destroy life as we know it, with rising sea levels, crippling droughts, and catastrophic floods sounding the alarm on a future now upon us. How did we get here and what must be done? In this incisive book, Kate Ervine unravels carbon's distinct political economy, arguing that, to understand global warming and why it remains so difficult to address, we must go back to the origins of industrial capitalism and its swelling dependence on carbon-intensive fossil fuels - coal, oil, and natural gas - to grease the wheels of growth and profitability. Taking the reader from carbon dioxide as chemical compound abundant in nature to carbon dioxide as greenhouse gas, from the role of carbon in the rise of global capitalism to its role in reinforcing and expanding existing patterns of global inequality, and from carbon as object of environmental governance to carbon as tradable commodity, Ervine exposes emerging struggles to decarbonize our societies for what they are: battles over the very meaning of democracy and social and ecological justice.

This book looks at the current state of food security and climate change, discusses the issues that are affecting them, and the actions required to ensure there will be enough food for the future. By casting a much wider net than most previously published books--to include select novel approaches, techniques, genes from crop diverse genetic resources or relatives--it shows how agriculture may still be able to triumph over the very real threat of climate change. Food Security and Climate Change integrates various challenges posed by changing climate, increasing population, sustainability in crop productivity, demand for food grains to sustain food security, and the anticipated future need for nutritious quality foods. It looks at individual factors resulting from climate change, including rising carbon emission levels, increasing temperature, disruptions in rainfall patterns, drought, and their combined impact on planting environments, crop adaptation, production, and management. The role of plant genetic resources, breeding technologies of crops, biotechnologies, and integrated farm management and agronomic good practices are included, and demonstrate the significance of food grain production in achieving food security during climate change. Food Security and Climate Change is an excellent book for researchers, scientists, students, and policy makers involved in agricultural science and technology, as well as those concerned with the effects of climate change on our environment and the food industry.

This book offers a broad range of options for technically adapting, handling and processing wood with specific wood characteristics. It starts by discussing wood anatomy and the general factors leading to the formation of wood characteristics. The individual characteristics are then categorized into four groups: 1. Wood characteristics inherent in a tree s natural growth. 2.Biotically-induced wood characteristics. 3.Abiotically-induced wood characteristics. 4. Types and causes of cracks.
New to this English edition is a comparison of wood characteristics found in trees from the boreal, temperate and tropical climate zones. The results show a clear relationship between the effects of sunshine duration, the vertical and horizontal angle of radiation, and crown coverage and the way wood characteristics form.
The book addresses all those who work with wood professionally: foresters, gardeners and arborists who want to be able to observe a living tree and identify its internal features and the causes of its prominent wood characteristics. Based on the findings described in this book they can determine how to avoid certain undesirable characteristics, or alternatively how to promote favorable ones as the tree and stand grow. Botanists and dendrologists will learn how wood characteristics arise, and how they affect living trees and wood products. The needs of wood technologists seeking to prevent adverse wood characteristics from influencing wood processing, or to enhance favorable wood characteristics, are also addressed.

By 2050, the world's population is estimated to grow to 10 billion. To feed everyone, we will have to double our food production, to produce more food in the next 40 years than in the whole of the last 6,000. Changing the Food Game shows how our unsustainable food production system cannot support this growth. In this prescient book, Lucas Simons argues that the biggest challenge for our generation can only be solved by effective market transformation to achieve sustainable agriculture and food production. Lucas Simons explains clearly how we have created a production and trading system that is inherently unsustainable. But he also demonstrates that we have reason to be hopeful - from a sustainability race in the cocoa industry to examples of market transformation taking place in palm oil, timber, and sugarcane production. He also poses the question: where next? Provocative and eye-opening, Changing the Food Game uncovers the real story of how our food makes it on to our plates and presents a game-changing solution to revolutionize the industry.

It follows an average days' worth of food and drink to see where it comes from, how far it travels, and the carbon price we all pay for it. From our breakfast tea and toast, through breaktime chocolate bar, to take-away supper, Dave Reay explores the weather extremes the world's farmers are already dealing with, and what new threats climate change will bring. Readers will encounter heat waves and hurricanes, wildfires and deadly toxins, as well as some truly climate-smart solutions. In every case there are responses that could cut emissions while boosting resilience and livelihoods. Ultimately we are all in this together, our decisions on what food we buy and how we consume it sends life-changing ripples right through the global web that is our food supply. As we face a future of 10 billion mouths to feed in a rapidly changing climate, it's time to get to know our farmers and herders, our vintners and fisherfolk, a whole lot better.
Many arborists learn tree work practices without fully understanding the biological and physiological principles behind them. However, outcomes for the health and longevity of trees are greatly improved when an arborist understands the science behind the care of tree root systems and crowns. In Applied Tree Biology, Drs. Hirons and Thomas draw upon their decades of experience in the laboratory, classroom, and the field - as well as the expertise of distinguished contributors to this volume - to provide those responsible for tree care with the scientific information that informs best practices for planting, pruning, soil decompaction, irrigation, and much more. Takes a multidisciplinary approach, integrating knowledge from plant biology, physiology, arboriculture, ecology, and more Provides a systematic presentation of fundamental tree biology and the scientific principles informing high quality tree care Presents accessible scientific information and best practices that help promote the health and longevity of trees Reflects the authors' decades of experience as tree biology researchers and educators, as well as their years of professional experience across the globe Applied Tree Biology is an indispensable source of practical, succinct information on tree biology, physiology, and ecology for professionals and interested amateurs involved with the care of trees. Arborists, foresters, and horticulturists at all stages of their careers will find this text particularly useful.
In 1920, 14 percent of all land-owning US farmers were black. Today less than 2 percent of farms are controlled by black people a loss of over 14 million acres and the result of discrimination and dispossession. While farm management is among the whitest of professions, farm labour is predominantly brown and exploited, and people of colour disproportionately live in food apartheid neighbourhoods and suffer from diet-related illness. The system is built on stolen land and stolen labour and needs a redesign. Farming While Black is the first comprehensive how to guide for aspiring African-heritage growers to reclaim their dignity as agriculturists and for all farmers to understand the distinct, technical contributions of African-heritage people to sustainable agriculture. At Soul Fire Farm, author Leah Penniman co-created the Black and Latinx Farmers Immersion (BLFI) program as a container for new farmers to share growing skills in a culturally relevant and supportive environment led by people of colour. Farming While Black organizes and expands upon the curriculum of the BLFI to provide readers with a concise guide to all aspects of small-scale farming, from business planning to preserving the harvest. Throughout the chapters Penniman uplifts the wisdom of the African diasporic farmers and activists whose work informs the techniques described from whole farm planning, soil fertility, seed selection, and agroecology, to using whole foods in culturally appropriate recipes, sharing stories of ancestors, and tools for healing from the trauma associated with slavery and economic exploitation on the land. Woven throughout the book is the story of Soul Fire Farm, a national leader in the food justice movement. The technical information is designed for farmers and gardeners with beginning to intermediate experience. For those with more experience, the book provides a fresh lens on practices that may have been taken for granted as ahistorical or strictly European. Black ancestors and contemporaries have always been leaders and continue to lead in the sustainable agriculture and food justice movements. It is time for all of us to listen.
The globalization of goods, services and capital for agriculture is fundamental to the future of developing countries and has major implications for the fight against poverty and sustainability of the environment. In recent years, agriculture has once again returned to a position of centre stage as food price volatility has led countries to re-examine their development strategies.
This new edition of the essential textbook in the field builds on the 2006 original and reflects the following developments:
The book contains a wealth of real world case studies and is now accompanied by a website that includes powerpoint lectures, a photo bank and a large set of discussion and exam questions.The accompanying website is available to view at http: //ecagdev.agecon.vt.edu/
This book takes readers on a journey through the evolution of agricultural communities in southern India, from their historical roots to the recent global neo-liberal era. It offers insights into a unique combination of themes, with a particular focus on agrarian change and urbanisation, specifically in the state of Karnataka where both aspects are significant and co-exist. Based on case studies from Karnataka in South India, the book presents a regional yet integrated multi-disciplinary framework for analysing the persistence, resilience and future of small farmer units. In doing so, it charts possible futures for small farm holdings and identifies means of integrating their progress and sustainability alongside that of the rest of the economy. Further, it provides arguments for the relevance of small holdings in connection with sustainable livelihoods and welfare at the grass roots, while also catering to the welfare needs of society at the macro level. The book makes a valuable contribution to the scholarship of agrarian as well as peri-urban transdisciplinary literature. For agrarian academics, students and the teaching community, the book's broad and topical coverage make it a valuable resource. For development practitioners and for those working on issues related to urbanisation, urban peripheries and the rural-urban interface, this book offers a new perspective that considers the primary sector on par with the secondary and tertiary. It also offers an insightful guide for policymakers and non-government organisations working in this area.
