This paper reviews the concept of adaptation of human communities to global changes, especially climate change, in the context of adaptive capacity and vulnerability. It focuses on scholarship that contributes to practical implementation of adaptations at the community scale. In numerous social science fields, adaptations are considered as responses to risks associated with the interaction of environmental hazards and human vulnerability or adaptive capacity. In the climate change field, adaptation analyses have been undertaken for several distinct purposes. Impact assessments assume adaptations to estimate damages to longer term climate scenarios with and without adjustments. Evaluations of specified adaptation options aim to identify preferred measures. Vulnerability indices seek to provide relative vulnerability scores for countries, regions or communities. The main purpose of participatory vulnerability assessments is to identify adaptation strategies that are feasible and practical in communities. The distinctive features of adaptation analyses with this purpose are outlined, and common elements of this approach are described. Practical adaptation initiatives tend to focus on risks that are already problematic, climate is considered together with other environmental and social stresses, and adaptations are mostly integrated or mainstreamed into other resource management, disaster preparedness and sustainable development programs. r 2006 Elsevier Ltd.

Adaptation, adaptive capacity and vulnerability

Objective. County-level socioeconomic and demographic data were used to construct an index of social vulnerability to environmental hazards, called the Social Vulnerability Index (SoVI) for the United States based on 1990 data.

Methods. Using a factor analytic approach, 42 variables were reduced to 11 independent factors that accounted for about 76 percent of the variance. These factors were placed in an additive model to compute a summary score—the Social Vulnerability Index.

Results. There are some distinct spatial patterns in the SoVI, with the most vulnerable counties clustered in metropolitan counties in the east, south Texas, and the Mississippi Delta region.

Conclusion. Those factors that contribute to the overall score often are different for each county, underscoring the interactive nature of social vulnerability—some components increase vulnerability; others moderate the effects.

Social Vulnerability to Environmental Hazards

There is considerable research interest on the meaning and measurement of resilience from a variety of research perspectives including those from the hazards/disasters and global change communities. The identification of standards and metrics for measuring disaster resilience is one of the challenges faced by local, state, and federal agencies, especially in the United States. This paper provides a new framework, the disaster resilience of place (DROP) model, designed to improve comparative assessments of disaster resilience at the local or community level. A candidate set of variables for implementing the model are also presented as a first step towards its implementation.

A place-based model for understanding community resilience to natural disasters

This article reviews the recent literature on diversification as a livelihood strategy of rural households in developing countries, with particular reference to sub‐Saharan Africa. Livelihood diversification is defined as the process by which rural families construct a diverse portfolio of activities and social support capabilities in order to survive and to improve their standards of living. The determinants and effects of diversification in the areas of poverty, income distribution, farm output and gender are examined. Some policy inferences are summarised. The conclusion is reached that removal of constraints to, and expansion of opportunities for, diversification are desirable policy objectives because they give individuals and households more capabilities to improve livelihood security and to raise living standards.

Household strategies and rural livelihood diversification

Social and ecological vulnerability to disasters and outcomes of any particular extreme event are influenced by buildup or erosion of resilience both before and after disasters occur. Resilient social-ecological systems incorporate diverse mechanisms for living with, and learning from, change and unexpected shocks. Disaster management requires multilevel governance systems that can enhance the capacity to cope with uncertainty and surprise by mobilizing diverse sources of resilience.

Social-Ecological Resilience to Coastal Disasters

Many disasters are a complex mix of natural hazards and human action. At Risk argues that the social, political and economic environment is as much a cause of disasters as the natural environment. Published within the International Decade of Natural Hazard Reduction, this book suggests ways in which both the social and natural sciences can be analytically combined through a 'disaster pressure and release' model. Arguing that the concept of vulnerability is central to an understanding of disasters and their prevention or mitigation, the authors explore the extent and ways in which people gain access to resources. Individual chapters apply analytical concepts to famines and drought, biological hazards, floods, coastal storms, and earthquakes, volcanos and landslides - the hazards that become disasters'. Finally, the book draws practical and policy conclusions to promote a safer environment and reduce vulnerability.

At Risk: Natural Hazards, People's Vulnerability and Disasters

Shelter after disaster

Born between the Wars, British suburbia has endured and prospered, despite being so often the butt of architectural and social snobbery. In words and pictures, this book investigates the suburbs in which half the population of Britain live.

Dunroamin': The Suburban Semi and Its Enemies

Disasters can dominate newspaper headlines and fill our TV screens with relief appeals, but the complex long-term challenge of recovery—providing shelter, rebuilding safe dwellings, restoring livelihoods and shattered lives—generally fails to attract the attention of the public and most agencies. On average 650 disasters occur each year. They affect more than 200 million people and cause $166 trillion of damage. Climate change, population growth and urbanisation are likely to intensify further the impact of natural disasters and add to reconstruction needs. Recovery from Disaster　explores the field and provides a concise, comprehensive source of knowledge for academics, planners, architects, engineers, construction managers, relief and development officials and reconstruction planners involved with all sectors of recovery, including shelter and rebuilding. With almost 80 years of first-hand experience of disaster recovery between them, Ian Davis (an architect) and David Alexander (a geographer) draw substantially from first-hand experiences in a variety of recovery situations in China, Haiti, Italy, Japan, New Zealand, Pakistan, the Philippines and the USA.
The volume is further enriched by two important and unique features: 21 models of disaster recovery are presented, seven of which were specifically developed for the book. The second feature is a survey of expert opinion about the nature of effective disaster recovery—the first of its kind. More than 50 responses are provided in full, along with an analysis that integrates them with the theories that underpin them. By providing a framework and models for future study and applications, Davis and Alexander seek both to advance the field and to provide a much-needed reference work for decision makers. With a broad perspective derived from the authors' roles held as university professors, researchers, trainers, consultants, NGO directors and advisors to governments and UN agencies, this comprehensive guide will be invaluable for practitioners and students of disaster management.
