Book Description
The authors critically review the literature on the net domestic (within-country) economic benefits of protecting tropical forests, focusing on hydrological benefits and the production of nontimber forest products. (The review does not consider other important classes of benefits, including global benefits of all kinds, ecological benefits which do not have instrumental economic value, and the existence value of forests.) Their main conclusions: (1)The level of net domestic benefits from forest preservation is highly sensitive to the alternative land use and to local climatic, biological, geological, and economic circumstances. When the alternative use is agroforestry or certain types of tree crops, the preservation of natural forests may yield no instrumental domestic benefits. (2)The hydrological benefits from forest preservation are poorly understood and likely to be highly variable. They may also be fewer than popularly assumed: Deforestation has not been shown to be associated with large-scale flooding. Tropical deforestation is generally associated with higher, not lower, dry season flows. Although it is plausible that deforestation should affect local precipitation, the magnitude and even the direction of the effects are unknown, except in the special case of cloud forests that quot;harvestquot; passing moisture. The link between deforestation and downstream sediment damage is sensitive to the basic topography and geology. Where sediment transport is slow - as in large, low-gradient basins - downstream impacts may manifest themselves in the distant future, so that the net present value of damage is small. Steep basins near reservoirs or marine fisheries, on the other hand, can cause substantial damage if land cover is severely disturbed. But only a few pioneering studies have examined the economics of reservoir sedimentation, and improved models of both sediment transport and dam function are needed. (3) The most impressive point estimates of forest value based on nontimber forest products are often based on atypical cases of faulty analysis. Where domesticated or synthetic substitutes exist, the nontimber forest product-related rents for natural forests will usually be driven toward zero.

Book Description
Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

Book Description
Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.

Book Description
Tropical forests are vanishing at an alarming rate. This book, based on extensive international field research, highlights one solution for preserving this precious resource: empowering local people who depend on the forest for survival. Synthesizing a vast amount of information that has never been brought together in one place, Roger D. Stone and Claudia D'Andrea provide a clearly written and energizing tour of global efforts to empower community-based forest stewards. Along the way, they show the fundamental importance of tropical forest ecosystems and deepen our sense of urgency to save them for the benefit of billions of rural people in tropical and subtropical regions as well as for countless species of plants and animals. In their travels to research this book, the authors saw many remarkable examples of how proficient even the poorest local people can be in stabilizing and recovering formerly destitute forests. With engagingly written case studies from Thailand's Golden Triangle to Mindanao in the Philippines, from Indonesia, India, and Africa to Brazil, Mexico, and Central America, they introduce us to the communities and the individuals, the governments, the loggers, the agencies, and the local groups who vie for forest resources. Contrasting community-based efforts and traditional forest management with government and donor efforts, they discuss the many reasons why international institutions and national governments have been unable and unwilling to stem the accelerating loss of tropical forestland. This book argues we are paying a terrible price--politically, economically, and environmentally--for allowing tropical forests to be stripped. Community-based forestry is no panacea, but this book clearly shows its effectiveness as a management technique.

Book Description
This book breaks new ground by accounting for the welfare implications of both severe inequality and environmental degradation and developing a sustainable development indicator that incorporates changes over time in each of these dimensions. The model is applied to data from Brazil spanning the 1965 -1998 period. The book's findings cast significant doubt on the proposition that rapid economic growth in Brazil has resulted in comparable welfare gains. The evidence presented more generally illustrates the often unsustainable nature of rapid GDP growth phases, as well as the general unreliability of GDP growth as an indicator of well-being improvement. The specific policy implication is that Brazil should discontinue - or at least severely curtail - the regressive and resource intensive economic policies it has followed in recent decades in the interest of welfare improvement not only for the poorer groups in society, but for future generations of Brazilians as well.

Book Description
Africa is not merely an invention with a modern, imperial or colonial background. Nor is it simply a continent in need of foreign aid from the richer, more affluent societies. Africa might be economically needy, politically unstable, and, in part, socially chaotic and suffering from civil wars and social unrest. However, the continent and its peoples are certainly different from the negative image portrayed in the mass media. Africa had been the cradle of civilization in the pre-colonial era, and is today undergoing a diverse cultural, philosophical, and spiritual development with great potential, contributing to contemporary debates around the ethics of globality. The novelty of this book derives from its multidisciplinary approach. Although the authors generally come from the fields of development and economics, global studies, political science, philosophy and ethics, and sociology, they present Africa’s alternative view of human wellbeing in order to provide theories and policy recommendations which inspire the specific developmental patterns for the growth of the continent. The volume discusses the meaning of development for the continent by drawing on culture, identity, ethnicity, and philosophy of nature. The contributors examine a variety of issues and themes directly related to the opportunities provided by globality to promote the development of the continent. They also discuss solutions for underdevelopment and poverty, and how those perspectives might be effectively integrated into the global agenda for the development of Africa.
