Flood resilience assessment from the perspective of urban (in)formality in Surat, India : implications for sustainable development

Abstract

Urbanization has resulted in increasing the pace of informality, specifically in developing countries like India. Informality is taking place at locations that are exposed to various hazards, and therefore, resilience building of both informal and formal settlements is needed to achieve sustainable development. Resilience assessment is key in defining appropriate area-specific resilience measures. Given that, this research assesses the resilience of formal and informal settlements of Surat city in India and presents implications for sustainable development. To assess resilience, an indicator-based approach was taken, using a household survey to collect the data. Analysis suggests that the resilience of formal and informal settlements is significantly different. Key differences were found in physical and institutional resilience, where informal settlements were found to be significantly less resilient than formal settlements. Several measures, such as gender-sensitive education and livelihood programs, as well as mobile water and sanitation, have positive implications for sustainable development. Overall, the study can guide disaster managers and policy makers to adopt a strategic and more targeted approach to strengthen resilience and achieve sustainable development.
