Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.
Building on recent scholarship in the sociology of food, Claire Lamine uses in-depth case studies from France and Brazil to compile a critical survey of social science approaches to sustainability transitions in agri-food systems. Lamine addresses the diverse pathways of transition encountered across multiple levels, from the farm through farmers' networks and food chains, to the territorial scale of regions. She also explores the efforts made by those involved in the agricultural world to create new connections between agriculture, food, environment and health, while also taking social equity issues into account. The book adopts a comparative perspective to explore the translation of agroecology into government programmes and the specific modes of governance involved in France and Brazil - two countries that pioneer in implementing agroecology yet which differ both in visions and context. Providing new options for understanding the complex issue of agri-food transitions, this book will make an impact for those studying food systems, geography, sociology, politics and agriculture.
Marine, coastal and wetland habitats are threatened, through exploitation, and also by climate change, as ocean currents change course, sea levels rise, and rainfall patterns change. This book gathers papers on the biodiversity conservation of these increasingly threatened habitats. The papers provide a snapshot of the problems they face, and offer numerous examples which render this volume valuable to educators in marine, freshwater and wetlands ecology, conservation and ecological restoration.
Conifer Cold Hardiness provides an up-to-date synthesis by leading scientists in the study of the major physiological and environmental factors regulating cold hardiness of conifer tree species. This state-of-the-art reference comprehensively explains current understanding of conifer cold hardiness ranging from the gene to the globe and from the highly applied to the very basic. Topics addressed encompass cold hardiness from the perspectives of ecology, ecophysiology, acclimation and deacclimation, seedling production and reforestation, the impacts of biotic and abiotic factors, and methods for studying and analyzing cold hardiness. The content is relevant to geneticists, ecologists, stress physiologists, environmental and global change scientists, pathologists, advanced nursery and silvicultural practitioners, and graduate students involved in plant biology, plant physiology, horticulture and forestry with an interest in cold hardiness.
