They are regarded as particularly vulnerable, but from a different point of view, island societies also feature a particular sociocultural resilience, which distinguishes them from continental societies. How do social structures increase the adaptive capacity of small islands towards sea-level rise? I consider the concept of social capital as applicable in order to understand the role of communities and collective action in a context of vulnerability and resilience. In this paper, I present results from a case study on the Isles of Scilly, UK. A mixed methods qualitative approach has been applied to analyse the various roles of social capital for the adaptation to climate change impacts on this small archipelago, which is representative of European small islands in an economically advanced, but isolated context. The Isles of Scilly are among the most vulnerable island regions in Europe. The results of the research contribute to the general discussion on social capital and the relevance of collective action for the adaptation to global climate change. How useful is the concept? And how relevant is it for small islands, such as the Isles of Scilly?

It is a great challenge for island societies rise of 20 cm during the last century has already led to and decision-makers to find socially, ecologically, coastal land loss on many islands (cf.

What then shapes an island’s vulnerable to sea-level rise – hazards that are resilience, especially in the context of climate expected to increase with future climate change. Due change? Islanders have developed ways to deal with a to their geologic history and vulnerability towards limited base of resources for centuries and with rare or further sea-level rise, the islands have been described unreliable contact to other world regions (Kerr 2005, as a ‘drowned landscape’ (Thomas 1985), and the 504).

On the other hand, the islands depend effective networks for emergency response than on their own capacity to solve problems (cf. Grydehøj official programs in western countries. And Rainbird 2013). I consider the Isles of Scilly as representative of (2007, 173) observes a ‘distinct community identity a small dependent island territory that is vulnerable to located historically on sea and land’. the projected impacts from global climate change, but, in contrast to the discussion on SIDS (cf.

By means of qualitative interviews, participant Social capital theory observation, and literature review, I analyse the potential and limitations of social capital in its Social capital is a concept that is applied across the different dimensions for climate change adaptation on range of foci in social sciences. Originating in the Isles of Scilly. sociology with a focus on the individual – social capital as a resource that is beneficial for one’s individual status within society (Bourdieu 1983; Small island vulnerability Coleman 1988) – the concept has found large interest Small islands are often considered as particularly among scholars dealing with economics, institutions, sensitive and vulnerable places, summarised, amongst and regional development discrepancies since the others, in the concept of the ‘isola effect’ (Moro et al. work of the political scientist Robert Putnam (2000; 2005). Kerr (2005) distinguishes issues of location Putnam et al. 1993). He analysed social capital from a and scale. Issues of location include expensive and collectivist point of view and defines it as ‘. features unreliable transport (Brookfield 1990, 25), and of social organization, such as trust, norms, and physical vulnerability to environmental changes. networks, that can improve the efficiency of society by Issues of scale refer especially to economic and facilitating coordinated actions’ (Putnam et al. 1993, structural features.
