Abstract: City planning with regard to green areas development can significantly offer a low cost and simple remedy to the impact of climate change in urban areas. This study examines green areas planning strategies as a means of mitigating urban heat island in Lafia town. The study discovered deficiencies in the development of green areas considering different land uses in Lafia town. The research used both primary and secondary data. Data deployed were used to calculate Normalized Difference Vegetation Index (NDVI); and the TIRS data were also used to derive LST. The boundaries of the urban area of Lafia town and the landscape indicators were interpreted and quantified based on high-resolution Google Earth images through manual interpretation based on the map of present land use. It is therefore recommended that green space should not be 300metres away from each other for optimum cooling. Also, vegetation and trees provides shade from direct sunlight radiation. The study further proposed a strategic base map of green areas planning to resolve the deficiencies and also made useful recommendations to stakeholders, policy makers and urban planners which when followed will provide green areas in Lafia town to enhance better health, a beautiful environment and urban heat island mitigation.
