Apart from these large scale interventions imposed by the central government, small-scale interventions taken at the neighborhood or household level could further contribute to mitigate future flood risk and to enhance the flood resilience of the city of Bangkok as a whole. Interventions taken at the local scale are often referred to as autonomous adaptation and may eventually lead to maladaptation if these individual actions are not coordinated and aligned with interventions taken at the larger scale (city level) and even beyond. This paper aims to identify and value the adaptation potential of existing (local) infrastructure, buildings and public spaces which may arise from autonomous local scale retrofitting and maintenance activities. A flood prone district of Bangkok. Lad Krabang district, has been used to provide a concrete context for this case study. The adaptation potential depends largely on (i) the lifespan and lifecycle of the individual elements of the existing urban infrastructure and (ii) the potential synergies which may arise from taking these individual elements together in one aggregated and integrated adaptation intervention (cluster). A lifecycle-based assessment method has been developed to assess the adaptation potential identified in the case study area for the time period 2014–2064 for the coming 5 decades.

These include drought, heat stress and most prominently increased flooding (Alves & Raman, 2017; Ayog et al., 2017; Cao et al., 2015; Darajeh et al., 2016; Gnansounou et al., 2014; Raman et al., 2018)[5,10,13,18,38,41]. Depending on where the city is located, flood disasters are often the result of a combination of coastal flooding, river flooding and urban flooding due to extreme rainfall. The latter one is typically occurring in cities located in monsoon-driven climates. Adapting to climate change is increasingly a high priority for cities (Araos et al., 2016; Clemens et al., 2015; Loo et al., 2015; Shyam et al., 2017)[2,12,25,27,42,46]. Since climate change is associated with large uncertainties, the exact requirements for cities to adapt to future conditions are changing and unclear (Chu et al., 2017;
