With effective climate change mitigation policies still under development, and with even the most aggressive proposals unable to halt climate change immediately, many decision makers are focusing unprecedented attention on the need for strategies to adapt to climate changes that are now unavoidable. The effects of climate change will touch every corner of the world's economies and societies; adaptation is inevitable. The remaining question is to what extent humans will anticipate and reduce undesired consequences of climate change, or postpone response until after climate change impacts have altered ecological and socioeconomic systems so significantly that opportunities for adaptation become limited. This book summarizes a National Research Council workshop at which presentations and discussion identified specific needs associated with this gap between the demand and supply of scientific information about climate change adaptation.

The possible impacts of global climate change on different countries has led to the development and ratification of the Framework Convention on Climate Change (FCCC) and has a strong bearing on the future sustainable development of developing countries and countries with economies in transition. The preparation of analytical methodologies and tools for carrying out assessments of vulnerability and adaptation to climate change is therefore of prime importance to these countries. Such assessments are needed to both fulfill the reporting requirements of the countries under the FCCC as well as to prepare their own climate change adaptation and mitigation plans. The vulnerability and adaptation assessment guidelines prepared by the U.S. Country Studies Program bring together all the latest knowledge and experience from around the world on both vulnerability analysis as well as adaptation methodologies. It is currently being applied successfully by scientists in over fifty countries from all the regions of the globe. This guidance is being published to share it with the wider scientific community interested in global climate change issues. This guidance document has two primary purposes: • To assist countries in making decisions about the scope and methods for their vulnerability and adaptation assessments, • To provide countries with guidance and step-by-step instructions on each of the basic elements of vulnerability and adaptation assessments.

Provides a framework for considering the full range of approaches to vulnerability, impacts and adaptation assessment due to climate change. It aims to help professionals such as researchers, policymakers, sectoral planners and consultants to select the appropriate methods and tools for their particular context and adaptation situation.

Assessing the vulnerability of human populations to global environmental change, particularly climate change, is now the main imperative of research and international action. However, much of the research into vulnerability is not designed to feed directly into decision making and policy, creating a gap between the knowledge created by researchers and what is required by decision makers. This book seeks to rectify this problem and bridge the gap. It discusses vulnerability as the central theme and brings together many different applications from disaster studies, climate change impact studies and several other fields and provides the most comprehensive synthesis of definitions, theories, formalization and applications to date, illustrated with examples from different disciplines, regions and periods, and from local through to regional, national and international levels. Case study topics cover sea level rise, vulnerability to changes in ecosystem services, assessing the vulnerability of human health and 'double exposure' to climate change and trade liberalization amongst other issues. Research outcomes stress that science-policy dialogues must be transparent to be effective and concentrate on a mutual understanding of the concepts used. A key research finding is that the most useful information for decision makers is that which shows the separate causes and drivers of vulnerability, rather than presenting vulnerability in an aggregated form. The book concludes with a unifying framework for analysing integrated methodologies of vulnerability assessment and guiding how research and policy can be linked to reduce vulnerability.

'Sound and solid case studies on vulnerability and adaptation have been woefully lacking in the international discourse on climate change. This set of books begins to bridge the gap.' Achim Steiner, UN Under-Secretary General and Executive Director of United Nations Environment Programme 'Important reading for students and practitioners alike.' Martin Parry, Co-Chair, Working Group II (Impacts, Adaptation and Vulnerability), Intergovernmental Panel on Climate Change (IPCC) 'Fills an important gap in our understanding ... It is policy-relevant and deserves to be widely read.' Richard Klein, Senior Research Fellow, Stockholm Environment Institute (SEI), Sweden The Intergovernmental Panel on Climate Change (IPCC) concluded in its 2001 report that much of the developing world is highly vulnerable to adverse impacts from climate change. But the IPCC also concluded that the vulnerabilities of developing countries are too little studied and too poorly understood to enable determination of adaptation strategies that would be effective at reducing risks. These authoritative volumes, resulting from the work of the Assessments of Impacts and Adaptations to Climate Change (AIACC) project launched by the IPCC in 2002, are the first to provide a comprehensive investigation of the issues at stake. Climate Change and Vulnerability discusses who is vulnerable to climate change, the nature of their vulnerability and the causes of their vulnerability for parts of the world that have been poorly researched until now. Climate Change and Adaptation covers current practices for managing climate risks to food security, water resources, livelihoods, human health and infrastructure, needs for effective management of climate risks, the changing nature of the risks, strategies for adaptation, and the need to integrate these strategies into development planning and resource management.
