Forests are very important for the world's population and large and play critical role in the Earth's life support system, including global carbon and hydrological cycles. This publication provides an overview of the global trends in forest cover and looks specifically at the four largest forest ecosystems and analyses the trends and challenges in their conservation and management. It scrutinizes some of the key drivers behind forest loss, including the increasing demand for commodities and energy. Finally it reviews some of the best practices for sustainable management of forest, including regulatory regimes, participatory management and economic incentives

Faced with man-made climate change and the need to provide housing for a growing world population, society needs to rethink the way future buildings are made. Wood is a truly renewable building material that is unlimited in supply if its growth and harvest are sustainably managed. Recent technological advancements in engineering allow the use of timber for the construction of multi-story structures, turning our buildings into carbon sinks rather than becoming sources for CO2-emissions. The book presents convincing arguments for the increased use of wood as an alternative to more fossil fuel intensive building materials, with the goal of demonstrating that an integrated approach can have the potential for positive impact on the environment, local economies, and the building culture at large.

This summary of UNEP's activities in 2008 provides an overview of the organization's contribution to the fight against climate change in a year in which unequivocal evidence established that global warming is the defining challenge of our era. The report also looks at the broad range of other activities carried out by UNEP as it follows its mandate to provide environmental leadership and promote sustainable development.

This timely book contributes to discussions on the best legal practices to use to promote conservation, protection and sustainable use of biological diversity in forest and marine areas. The breadth of issues explored across these two themes is immense, and the book identifies both key differences, and striking commonalities between them.

The publication was prepared based on information provided by 86 countries, outcomes from regional and subregional consultations and commissioned thematic studies. It includes: •an overview of definitions and concepts related to Forest Genetic Resources (FGR) and a review of their value; •a description of the main drivers of changes; •the presentation of key emerging technologies; •an analysis of the current status of FGR conservation, use and related developments; •recommendations addressing the challenges and needs.

Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.

Firs and pines dominated the global picture of the raw materials for paper industry until the 1950s. At that time, the interest in introducing new species, mostly hardwoods, led the researchers intensify efforts to look for the fibrous characteristics and their combinations that could represent the relationship between fibres, pulp and paper.The pulp and paper industry has shown, mainly in the last two decades, a strong North-South displacement. This is to a large extent due to the favourable climate, which promote the development of the trees. Similarly, the paper fibres have gone from being almost exclusively softwoods from natural forests of the Northern-Hemisphere cold regions, such as spruce and fir, to fast growing species of short fibres, such as eucalyptus, and willow and poplar hybrids from plantations.These new species, that begin to dominate the paper panorama, not only differ from classic ones in fibre length, but they present particular characteristics, like large amounts of juvenile wood, different fibrillar angle and so on, because trees are used increasingly at younger age.This leads us to question whether the old paradigms concerning the relationships between fibres characteristics and pulp properties are still valid or should be reviewed and updated, in which case, the basic fibre parameters, their influence in pulping and refining, and their impact on paper quality should be redefined.To establish the state-of-the-art on the topic, this book analyses the publications of the last decade to verify the morphological characteristics of the fibres which are nowadays considered relevant. Relatively recent data were surveyed because of the continuous changes that occur in the species by genetic improvement.

Global Problems, Global Solutions: Prospects for a Better World approaches social problems from a global perspective with an emphasis on using one’s sociological imagination. Perfect for instructors who involve students in research, this text connects problems borne by individuals to regional, global and historical forces, and stresses the importance of evidence in forming opinions and policies addressing social issues. The book introduces readers to the complexities of the major problems that confront us today such as violent conflict, poverty, climate change, human trafficking and other issues that we encounter in our lives. It book concludes with a chapter on politics and government, underscoring the need for good governance at all levels–and cooperation among many layers of government–to build a better world.
