Also, developing countries share most of the urbanization problems in which poverty and housing inadequacy (comfort) are central issues; mostly among poor urban settlers. This paper examined prevalent environmental hazards promulgated by climate change in Nigeria; its resultant impact on the housing environment of the urban-poor; and, sustainable adaptation approaches to mitigate identified problems. Keywords: climate, housing, poverty, urbanization, sustainability. Introduction Housing is a basic need of man and remains central to his existence (Kehinde, 2010; Aribigbola, 2006). In urban areas, housing demand is not matched with adequate (quantity and quality) supply (Diogu, 2002). This problem is compounded by the fact that the greater urban population live in poverty. The poor urban populace are low income earners who do not have the financial means to acquire comfortable housing. However, the quality of living conditions within such housing settlements deteriorates further with the influence of climate change and environmental hazards. This leads to the development of slums and unhealthy environment (Akpodiogaga et al, 2017). It is against this backdrop that this paper examined
