Book Description
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.

Book Description
Many actions of human beings have led to deforestation which has resulted in loss of biodiversity and natural habitats. Therefore, forestry as a subject is very important, as it deals with process of creating, managing, repairing, covering forests and protecting other environmental habitats. Afforestation or reforestation refers to the process of planting trees in a space which was left barren before. This book mainly focuses on the subject of forestry, with special significance on the areas of deforestation and afforestation. The topics introduced in it cover many new and important theories as well as practices under this field. This textbook is an essential guide for both academicians and those who wish to pursue this discipline further.

Book Description
In large areas of developing countries the loss of trees is causing erosion and degradation of the soil, posing severe problems for economic development. By translating the ecological benefits of afforestation into economic terms, the author demonstrates how investments that benefit the environment often benefit the economy as well. Both the traditional work of the forestry services and tree plantings by farmers are needed, says the author, if deforestation is to be halted and reversed. With special refrence to Africa, he discusses the underlying reasons for deforestation, suggests policy changes to promote the planting and care of trees, and identifies issues for social and scientific research. A case study of the arid zone of northern Nigeria illustrates the benefits that could be brought about by establishing windbreaks and encouraging farmers to plant trees. Besides preventing soil erosion, improving soil fertility, and thus increasing crop prodution, trees provide fruit, livestock fodder, and much-needed fuelwood and building materials. The author compares the increase in farm incomes as a result of an afforestation program with the decrease in incomes if deforestation and soil erosion were to continue. The analysis will be of special interest to those concerned with agriculture, forestry, rural development, and environmental issues in developing countries.

Book Description
Global Deforestation provides a concise but comprehensive examination of the variety of ways in which deforestation modifies environmental processes, as well as the societal implications of these changes. The book stresses how forest ecosystems may be prone to nearly irreversible degradation. To prevent the loss of important biophysical and socioeconomic functions, forests need to be adequately managed and protected against the increasing demand for agricultural land and forest resources. The book describes the spatial extent of forests, and provides an understanding of the past and present drivers of deforestation. It presents a theoretical background to understand the impacts of deforestation on biodiversity, hydrological functioning, biogeochemical cycling, and climate. It bridges the physical and biological sciences with the social sciences by examining economic impacts and socioeconomic drivers of deforestation. This book will appeal to advanced students, researchers and policymakers in environmental science, ecology, forestry, hydrology, plant science, ecohydrology, and environmental economics.

Book Description
Does the diagnosis of irreversible destruction of both forests and their biodiversity actually mask a wide range of patterns? Based on the results of natural and social scientists, this book attempts to answer fundamental questions such as: what is deforestation and how do we mesure it? What changes result from deforestation and how do human societies manage these changes? It explores the many and varied aspects of deforestation, a process whose effects are not always as negative as perceived.

Book Description
North-central Namibia’s history demonstrates how global models of environmental change give rise to contradictory interpretations that are not simply misreadings of the same process. The area experienced both dramatic deforestation and reforestation, suggesting the need for new and pluralistic approaches.

Book Description
This paper presents a framework for analyzing tropical deforestation and reforestation using the von Thunen model as its starting point: land is allocated to the use which yields the highest rent, and the rents of various land uses are determined by location. Forest cover change therefore becomes a question of changes in rent of forest versus non-forest use. While this is a simple and powerful starting point, more intriguing issues arise when this is applied to analyze real cases. An initial shift in the rent of one particular land use generates feedbacks which affect the rent of all land uses. For example, a new technology in extensive agriculture should make this land use more profitable and lead to more forest clearing, but general equilibrium effects (changes in prices and local wages) can modify or even reverse this conclusion. Another issue is how a policy change or a shift in broader market, technological, and institutional forces will affect various land use rents. The paper deals with three such areas: technological progress in agriculture, land tenure regimes, and community forest management. The second part of the paper links the von Thunen framework to the forest transition theory. The forest transition theory describes a sequence over time where a forested region goes through a period of deforestation before the forest cover eventually stabilizes and starts to increase. This sequence can be seen as a systematic pattern of change in the agricultural and forest land rents over time. Increasing agricultural rent leads to high rates of deforestation. The slow-down of deforestation and eventual reforestation is due to lower agricultural rents (the economic development path) and higher forest rent (the forest scarcity path). Various forces leading to these changes are discussed and supported by empirical evidence from different tropical regions.
