Introduction to Climate Disasters and Coastal Socio-ecological Systems

This chapter discusses the complex relationship between climate disasters and coastal socio-ecological systems, stressing the urgent need for integrated and sustainability-oriented risk reduction. It begins by unpacking the concept, causes, and drivers of climate disasters, highlighting that such events are not purely natural but are socially mediated and exacerbated by anthropogenic pressures. The discussion then turns to the functioning of coastal socio-ecological systems, emphasising their ecological value, socio-cultural diversity, and vulnerability to hazards such as cyclones, sea-level rise, and erosion. The analysis explores coastal hazards and risks, outlining their typologies, underlying drivers, and diverse impacts. Ecological consequences such as mangrove degradation, coral bleaching, and wetland loss are examined alongside social outcomes including displacement, livelihood insecurity, and the erosion of cultural heritage. The chapter argues that climate disasters produce cascading and interlinked effects that destabilise both ecosystems and human communities, particularly in marginalised regions. In response, a comprehensive framework for coastal risk reduction is advanced, grounded in community participation, ecosystem restoration, and policy integration. Hard, soft, and hybrid protective strategies are evaluated, with particular emphasis on ecosystem-based approaches that promote equity and integrate local and traditional knowledge. The chapter concludes by highlighting key arguments and future research directions, including the need for gender-sensitive perspectives, migration and resettlement studies, and participatory governance. By adopting an interdisciplinary and systems-based approach, it offers critical insights into building resilient and sustainable coastal futures amidst intensifying climate uncertainty.
