Abstract

The characteristics of Ghanaian cities, typical of several others in Africa, are fast expanding and have inadequate capacity for solid waste management, good sanitation, clean water, housing and living spaces. The situation is compounded by increased frequency and intensity of weather events associated with climate change. This paper is aimed at examining the impacts of climate change on the housing environment in Ghana, and specifically addresses the following issues; how has the housing environment in Ghana experienced climate change? How can the housing environment in Ghana be physically planned to reduce their contribution to climate change? How can the housing environment in Ghana be planned and designed to adapt to climate change? Climatic data comprising temperature, humidity, rainfall spanning a thirty-year period representative of two regional capitals of Ghana is examined to establish their trends, and identify any linkages to the current housing environment. The cities are found to be vulnerable to multiple dimensions of climate change at rates higher than the global mean rates; in particular, increased temperature in the range of 0.035°C per annum manifesting in increased heat wave, reduced relative humidity levels at a rate of 0.23 per cent per annum, increased intensity of rainfall at a rate of 1.15mm per annumbut of reduced frequency, and reduced wind speeds. The effects of the observed changes challenge city authorities in the management of the city. It is expected to sensitize discussion on adaptation strategies and influence physical planning policies and guide green building initiatives aimed at promoting sustainable, resilient and livable cities
