This book gives an overview of the relationships between agriculture and air quality, which is an issue of increasing importance for practitioners and policy makers. It provides the keys to understand natural and anthropogenic mechanisms governing emission and deposition of pollutants produced by and/or impacting agricultural activities It identifies how management practices can help mitigating emissions and how public policies on air pollution progressively addressed the agricultural sector This book was written for students, researchers and agriculture actors as well as for public decision-makers
Drawing upon oral and documentary evidence, this volume explores the lives of noteworthy Mi’kmaw individuals whose thoughts, actions, and aspirations impacted the history of the Northeast but whose activities were too often relegated to the shadows of history. The book highlights Mi’kmaw leaders who played major roles in guiding the history of the region between 1680 and 1980. It sheds light on their community and emigration policies, organizational and negotiating skills, diplomatic endeavours, and stewardship of land and resources. Contributors to the volume range from seasoned scholars with years of research in the field to Mi’kmaw students whose interest in their history will prove...
Challenging established views and assumptions about traditions and practices of filmmaking in the African diaspora, this three-volume set offers readers a researched critique on black film. Volume One of this landmark series on African cinema draws together foundational scholarship on its history and evolution. Beginning with the ideological project of colonial film to legitimize the economic exploitation and cultural hegemony of the African continent during imperial rule to its counter-historical formation and theorization. It comprises essays by film scholars and filmmakers alike, among them Roy Armes, Med Hondo, Fèrid Boughedir, Haile Gerima, Oliver Barlet, Teshome Gabriel, and David Murphy, including three distinct dossiers: a timeline of key dates in the history of African cinema; a comprehensive chronicle and account of the contributions by African women in cinema; and a homage and overview of Ousmane Sembène, the "Father" of African cinema.
Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.

Anthropogenic emissions of ammonia cause a host of environmental impacts, including loss of biodiversity, soil acidification and formation of particulate matter in the atmosphere. Under the auspices of the UNECE Convention on Long Range Transboundary Air Pollution, around 80 international experts met to review the state of scientific knowledge. This book reports their analysis. It concludes that threshold levels for ammonia effects have been underestimated and sets new values, it assesses the independent evidence to verify reported reductions in regional ammonia emissions, and it reviews the uncertainties in modelling ammonia, both in "hot spots" and at the regional scale.
A collection of upwards of thirty thousand names of German, Swiss, Dutch, French and other immigrants in Pennsylvania from 1727 to 1776: With a Statement of the Names of Ships, Whence They Sailed, and the Date of Their Arrival at Philadelphia.
The landscape is widely identified as a relevant target both by integrative policies and across the disciplines dealing with resource management and territorial planning. Landscape agronomy promotes a greater involvement of agricultural sciences into this arena by increasing the attention on the dynamics relating the farming practices to the natural resources and the temporal and spatial patterns of land covers. This book covers the background that improved the transdisciplinary interface of agronomy with spatially-explicit disciplines like landscape ecology and geography both in research and in training programs, in addition to some experiences of participative landscape management.
