This book sets out a series of techniques that have been developed to estimate the environmental impact of afforestation. It offers guidelines and decision support systems (DSS) to enable national and international policy makers as well as forest managers to maximize the benefits and minimize the adverse effects of afforestation. This book summarizes afforestation research and shows the application of the developed decision support system.
The book is a comprehensive manual of practice for execution of afforestation and tree planting programmes in arid and semi-arid tropics. It includes a compact running account of the technology of afforestation and the relevant principles and practices in management of afforestation projects. It provides a wide range of structured information and a number of model designs which can be gainfully put to use by the field level supervisors as also by the managers concerned with planning and control of such projects. Written by a practising specialist, the book is invaluable for anyone concerned with the practice of afforestation and tree planting, be he a tree hobbyist or a school teacher, a professional forester or a senior policy maker in government, an industrialist or a philanthropist, an environmental activist or a member of a community service organization.
43 videnskabelige artikler fra et fællesnordisk projekt omkring indflydelsen af beskovning på økosystemer, landskab og regional udvikling. Projektet sammenligner skov, landskab og samfund i forskellige nordiske lande som har lignende samfundsstruktur, men er på meget forskellige niveauer med hensyn til beskovning og brug af skoven. I Danmark, Norge og Sverige har man arbejdet systematisk med at opbygge skovressourcerne igen, hvorimod man på Island og Færøerne kun lige er begyndt at planlægge arbejdet
Extermination of forests is an essential part of human activity since prehistoric times. There are several reasons for this: the forest is an enemy environment hiding predators and other threats; the forest is a source for wood, which is used for firing and materials of construction; forest occupies land, which could be used for agriculture. Even now in spite of progress in ecological education, deforestation continuously accelerates everywhere. This book provides new research on the global challenges and issues on deforestation in the 21st Century.

New edition of book which is a course text in woodland conservation and management. The text has been updated throughout and has a major new chapter dealing with developments in conservation and management policies over the last ten years in a European context, including developments in vegetation classification systems and outcomes of management policies.
How afforestation reveals the often-concealed politics between humans and plants In Plant Life, Rosetta S. Elkin explores the procedures of afforestation, the large-scale planting of trees in otherwise treeless environments, including grasslands, prairies, and drylands. Elkin reveals that planting a tree can either be one of the ultimate offerings to thriving on this planet, or one of the most extreme perversions of human agency over it. Using three supracontinental case studies—scientific forestry in the American prairies, colonial control in Africa’s Sahelian grasslands, and Chinese efforts to control and administer territory—Elkin explores the political implications of plant life as a tool of environmentalism. By exposing the human tendency to fix or solve environmental matters by exploiting other organisms, this work exposes the relationship between human and plant life, revealing that afforestation is not an ecological act: rather, it is deliberately political and distressingly social. Plant Life ultimately reveals that afforestation cannot offset deforestation, an important distinction that sheds light on current environmental trends that suggest we can plant our way out of climate change. By radicalizing what conservation protects and by framing plants in their total aliveness, Elkin shows that there are many kinds of life—not just our own—to consider when advancing environmental policy.
The Forestry and Agriculture Sector Optimization Model with Greenhouse Gases (FASOMGHG) has historically relied on regional average costs of land conversion to simulate land use change across cropland, pasture, rangeland, and forestry. This assumption limits the accuracy of the land conversion estimates by not recognizing spatial heterogeneity in land quality and conversion costs. Using data from Nielsen et al. (2014), we obtained the afforestation cost per county, then estimated nonparametric regional marginal cost functions for land converting land to forestry. These afforestation costs were then incorporated into FASOMGHG. Three different assumptions for land moving into the forest sector were run; constant average conversion cost, static rising marginal costs and dynamic rising marginal cost, in order to assess the implications of alternative land conversion cost assumptions on key outcomes, such as projected forest area and cropland use, carbon sequestration, and forest product output.
While the commitment to protect and restore forest ecosystems has become a policy goal in many countries since the Rio Conference, there is still no general consensus on what constitutes restoration. This authoritative reference presents the best practices for fostering increased sustainability, enhancing biodiversity, and repairing ecosystem func
