Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.

While a number of gases are implicated in global warming, carbon dioxide is the most important contributor, and in one sense the entire phenomena can be seen as a human-induced perturbation of the carbon cycle. The Global Carbon Cycle offers a scientific assessment of the state of current knowledge of the carbon cycle by the world's leading scientists sponsored by SCOPE and the Global Carbon Project, and other international partners. It gives an introductory over-view of the carbon cycle, with multidisciplinary contributions covering biological, physical, and social science aspects. Included are 29 chapters covering topics including: an assessment of carbon-climate-human interactions; a portfolio of carbon management options; spatial and temporal distribution of sources and sinks of carbon dioxide; socio-economic driving forces of emissions scenarios. Throughout, contributors emphasize that all parts of the carbon cycle are interrelated, and only by developing a framework that considers the full set of feedbacks will we be able to achieve a thorough understanding and develop effective management strategies. The Global Carbon Cycle edited by Christopher B. Field and Michael R. Raupach is part of the Rapid Assessment Publication series produced by the Scientific Committee on Problems of the Environment (SCOPE), in an effort to quickly disseminate the collective knowledge of the world's leading experts on topics of pressing environmental concern.

The lntergovernmental Panel on Climate Change (IPCC) has recently summarized the state ofthe art in research on climate change (Climate Change 1995). The most up to date research findings have been divided into three volumes: • the Science ofClimate Change (working group I), • the Impacts, Adaption and Mitigation of Climate Change (working group II), and • the Economic and Social Dimensions ofClimate Change (working group III) There is a general consensus that a serious change in climate can only be avoided if the future emissions of greenhouse gases are reduced considerably from the business as usual projection and if at the same time the natural sinks for greenhouse gases, in particular that of CO , are maintained at the present level or 2 preferrably increased. Forests, forestry and forestry industry are important parts of the global carbon cycle and therefore they are also part of the mitigation potentials in at least a threefold way: 1. During the time period between 1980 and 1989 there was a net emission of CO from changes in tropical land use (mostly tropical deforestation) of 2 1. 6 +/- 1 GtC/a, but at the same time it was estimated that the forests in the northem hemisphere have taken up 0. 5 +/- 0. 5 GtC/a and additionally other terrestrial sinks (including tropical forests where no clearing took place) have been a carbon sink ofthe order of l. 3 +/- l.

The earth`s atmosphere is made up of different layers. Gases such as Carbon dioxide, Methane, Nitrous oxide, chloroflurocarbons, Methyl bromide etc. make the atmosphere work like a greenhouse. These gases trap heat emitted by infrared wavelengths from the earths surface. This phenomenon is called greenhouse effect, and is responsible for the average temperature at the earth surface being 15c rather than -15 c the temperature it would be it there no atmosphere.

The United States Government, cognizant of its responsibilities to future generations, has been sponsoring research for nine years into the causes, effects, and potential impacts of increased concentrations of carbon dioxide (C0 ) in the atmosphere. Agencies such as the National Science Foun 2 dation, National Oceanic and Atmospheric Administration, and the U.S. Department of Energy (DOE) cooperatively spent about $100 million from FY 1978 through FY 1984 directly on the study of CO • The DOE, as the 2 lead government agency for coordinating the government' s research ef forts, has been responsible for about 60% of these research efforts. William James succinctly defined our purpose when he stated science must be based upon " ... irreducible and stubborn facts." Scientific knowledge can and will reduce the present significant uncertainty sur rounding our understanding of the causes, effects, and potential impacts of increasing atmospheric CO2• We have come far during the past seven years in resolving some underlyinig doubts and in narrowing the ranges of disagreement. Basic concepts have become less murky. Yet, much more must be accomplished; more irreducible and stubborn facts are needed to reduce the uncertainties so that we can improve our knowledge base. Uncertainty can never be reduced to zero. However, with a much improved knowledge base, we will be able to learn, under stand, and be in a position to make decisions.

The results presented in this book summarize the main findings of the CARBOFOR project, which brought together 52 scientists from 14 research units to investigate the effects of future climate on the carbon cycle, the productivity and vulnerability of French forests. This book explains the current forest carbon cycle in temperate and Mediterranean climates, including the dynamics of soil carbon and the total carbon stock of French forests, based on forest inventories. It reviews and illustrates the main ground-based methods for estimating carbon stocks in tree biomass. Spatial variations in projected climate change over metropolitan France throughout the 21st century are described. The book then goes on to consider the impacts of climate change on tree phenology and forest carbon balance, evapotranspiration and production as well as their first order interaction with forest management alternatives. The impact of climate change on forest vulnerability is analysed. A similar simulation study was carried out for a range of pathogenic fungi, emphasizing the importance of both warming and precipitation changes. The consequences of climate change on the occurrence of forest fires and the forest carbon cycle in the Mediterranean zone are also considered.A valuable reference for researchers and academics, forest engineers and managers, and graduate level students in forest ecology, ecological modelling and forestry.

Plantation forests often have a negative image. They are typically assumed to be poor substitutes for natural forests, particularly in terms of biodiversity conservation, carbon storage, provision of clean drinking water and other non-timber goods and services. Often they are monocultures that do not appear to invite people for recreation and other direct uses. Yet as this book clearly shows, they can play a vital role in the provision of ecosystem services, when compared to agriculture and other forms of land use or when natural forests have been degraded. This is the first book to examine explicitly the non-timber goods and services provided by plantation forests, including soil, water and biodiversity conservation, as well as carbon sequestration and the provision of local livelihoods. The authors show that, if we require a higher provision of ecosystem goods and services from both temperate and tropical plantations, new approaches to their management are required. These include policies, methods for valuing the services, the practices of small landholders, landscape approaches to optimise delivery of goods and services, and technical issues about how to achieve suitable solutions at the scale of forest stands. While providing original theoretical insights, the book also gives guidance for plantation managers, policy-makers, conservation practitioners and community advocates, who seek to promote or strengthen the multiple-use of forest plantations for improved benefits for society.

The importance of this book lies in being one of the first comprehensive attempts to summarise major findings in the field of carbon sinks and climate change. . . The book also deals comprehensively with the present and future role of forests in climate change policy and practice. . . This timely book is essential reading for policy decision-makers and foresters alike. Wasantha Athukorala, Economic Analysis and Policy Reforestation and avoiding deforestation are methods of harnessing nature to tackle global warming the greatest challenge facing humankind. In this book, Colin Hunt deals comprehensively with the present and future role of forests in climate change policy and practice. The author provides signposts for the way ahead in climate change policy and offers practical examples of forestry s role in climate change mitigation in both developed and tropical developing countries. Chapters on measuring carbon in plantations, their biodiversity benefits and potential for biofuel production complement the analysis. He also discusses the potential for forestry in climate change policy in the United States and other countries where policies to limit greenhouse gas emissions have been foreshadowed. The author employs scientific and socio-economic analysis and lays bare the complexity of forestry markets. A review of the workings of carbon markets, based both on the Kyoto Protocol and voluntary participation, provides a foundation from which to explore forestry s role. Emphasis is placed on acknowledging how forests idiosyncrasies affect the design of markets for sequestered carbon. The realization of forestry s potential in developed countries depends on the depth of cuts in greenhouse gas emissions, together with in-country rules on forestry. An increase in funding for carbon retention in tropical forests is an immediate imperative, but complexities dictate that the sources of finance will likely be dedicated funds rather than carbon markets. This timely and comprehensive book will be of great value to any reader interested in climate change. Policy-makers within international agencies and governments, academics and students in the fields of geography, economics, science policy, forestry, development studies as well as carbon market participants and forest developers in the private sector will find it especially useful.

The inclusion of forests as potential biological sinks in the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) in 1997 has attracted international attention and again has put scientific and political focus on the world's forests, regarding their state and development. The international discus sion induced by the Kyoto Protocol has clearly shown that not only the tropical rain forests are endangered by man's activities, but also that the forest ecosystems of boreal, temperate, mediterranean and subtropical regions have been drastically modified. Deforestation on a large scale, burning, over-exploitation, and the degra dation of the biological diversity are well-known symptoms in forests all over the world. This negative development happens in spite of the already existing knowledge of the benefits of forests on global energy and water regimes, the biogeochemical cycling of carbon and other elements as well as on the biological and cultural diversity. The reasons why man does not take care of forests properly are manifold and complex and there is no easy solution how to change the existing negative trends. One reason that makes it so difficult to assess the impacts of human activity on the future development of forests is the large time scale in which forests react, ranging from decades to centuries.

Among global environmental issues, climate change has received the largest attention of national and global policy makers, researchers, industry, multilateral banks and NGOs. Climate change is one of the most important global environmental problems with unique characteristics. It is global, long-term (up to several centuries) and involves complex interactions between climatic, environmental, economic, political, institutional and technological pressures. It is of great significance to developing countries as all the available knowledge suggests that they, and particularly their poorer inhabitants, are highly vulnerable to climate impacts. The projected warming of 1. 4 to 5. 8° C by 2100 and the related changes in rainfall pattern, rise in sea-level and increased frequency of extreme events (such as drought, hurricanes and storms) are likely to threaten food security, increase fresh water scarcity, lead to decline in biodiversity, increase occurrence of vector-borne diseases, cause flooding of coastal settlements, etc. Recognizing the potential threat of severe disruptions, the United Nations Conference on Environment and Development was organized in 1992 in Rio de Janeiro, Brazil to begin to address ways to reduce these impacts, which led to the formulation of the UN Framework Convention on Climate Change. This Convention and the subsequent Kyoto Protocol recognize “the common but differentiated responsibility” of developing and industrialized countries in addressing climate change. Developing countries thus have a unique role to play in formulating a sound, reasoned, and well informed response to the threat of climate change.
