This paper examines the impacts of climate disasters on informal settler families (ISFs), especially on vulnerable women (i.e., single-headed households of unmarried women, elderly, separated/divorced and/or widowed, etc.) and their related households. Climate disaster impacts are highly differentiated according to their socio-environmental vulnerabilities to climate and disaster risks of their households, communities, and cities. But their capacities to respond proactively and build their adaptive capacities toward their resilience are mediated by their social capital/trust networks, which can either aid or impede their ties to different power holders within/across households and communities.
