Recent scientific outputs suggest that climate change is likely to cause shifts in the global pattern and intensity of flood events, in some regions increasing the exposure of populations to severe flooding. Potential future risks underline the importance of research and intervention work aimed at strengthening local capacity to cope with flooding, especially for the poor in developing countries. This paper reviews recent theoretical and applied research on vulnerability and adaptive capacity of households and communities in flood-prone areas. It traces the growing tendency for interventions to prioritize action at the local scale and suggests directions for further research to deepen understanding of actual and potential coping strategies.

The Paris Agreement articulates a global goal on adaptation, which aims to ensure an ‘adequate adaptation response’ to the ‘global temperature goal’, and requires countries to report progress through periodic global stocktakes. However, there remain conceptual and methodological challenges in defining an adaptation goal and mixed evidence on what effective adaptation looks like and how it can be enabled. In this review, we demonstrate how different normative views on adaptation outcomes, arising from different epistemological and disciplinary entry points, can lead to very different interpretations of adaptation effectiveness. We argue that how effectiveness is framed will significantly impact adaptation implementation and outcomes. This, furthermore, represents a way of exercising influence in adaptation decision-making. Eleven principles of effective adaptation are distilled as a way to pluralize guidance in international processes such as the Global Stocktake as well as national and sub-national exercises on tracking and monitoring adaptation.

In recent years there has been a growing number of academic reviews discussing the theme of transformation and its association with adaptation to climate change. On the one hand this has stimulated exchange of ideas and perspectives on the parameters of transformation, but it has also given rise to confusion in terms of identifying what constitutes a non-incremental form of adaptation on the ground. What this article aims to do instead is help researchers and practitioners relate different interpretations of transformation to practice by proposing a typological framework for categorising forms of change that focuses on mechanisms and objectives. It then discusses how these categorisations link to the broader conceptions and critiques noted above, with the idea that this will enable those who seek to analyse or plan adaptation to better analyse what types of action are potentially constitutive of transformation. In doing so, it should equally assist in the identification and specification of critical questions that need to be asked of such activity in relation to issues of sustainability and equity.

This paper reviews the state of knowledge on social vulnerability to climate change in three hot spots (deltas, semi-arid regions and snowpack- or glacier-fed river basins) in Africa, Central Asia and South Asia, using elements of systematic review methods. Social vulnerability is defined as a dynamic state of societies comprising exposure, sensitivity and adaptive capacity. We examine whether the hot spots have specific characteristics that tend to increase or decrease social vulnerability, consider suitable scales of analysis for understanding vulnerability, and explore the conceptions of vulnerability adopted in the climate change literature and the nature of the insights this generates. Finally, we identify knowledge gaps in this literature. All three hot spots are characterized by high levels of natural resource dependence, with increasing environmental degradation. They also exhibit unequal policies and patterns of development, which benefit certain segments of society while making others more vulnerable. Vulnerability is driven by multiple factors operating at different scales; however, characterization of cross-scalar interactions is poorly developed in the majority of studies reviewed. Most studies are either large scale, such as broad comparisons of vulnerability across countries, or local, documenting community-level processes. Detailed understanding of the interactions between climate change impacts on natural systems, and socio-economic trajectories, including adaptation, also emerges as a knowledge gap.

Climate change may lead to shifts in the distribution and prevalence of a range of diseases that already pose severe health threats in many developing countries. In order to understand better both human vulnerability to those changes and prospects for adaptation, it is important to direct research attention in this field to aspects of the health behaviour of people currently exposed to disease risk. This review paper explores the potential for building on health behaviour theory to frame analysis of adaptive capacity to climate-sensitive infectious diseases at the grassroots level. It focuses on vector-borne diseases currently endemic in many lower-income countries and draws on existing behavioural studies to examine the applicability and limitations of a social cognitive approach. The review suggests that such an approach has clear value for deepening analysis of adaptive capacity, but needs to be complemented by a wider understanding of how adaptive behaviour is likely to be socially structured, economically constrained and modified over time.
