Abstract
The use of green roofs especially the extensive type has become an important component of the "soft" engineering approach to environmental management of urban areas. Green roofs have been used in many parts of the world where they have been found to be beneficial in storm-water management, noise and thermal insulation as well as for mitigation of urban heat island effects. Lagos, a highly urbanized Nigerian city is characterized by a rapidly growing population within a very limited land area. The resultant development pressure on land has given rise to dense urban fabric with associated loss of green cover thereby eliciting suggestions for the adoption of green roofs. This aim of this paper is to examine opportunities for and identify barriers to the adoption of green roofs in Lagos, Nigeria. A combined quantitative and qualitative research strategy was adopted for the study. Questionnaire administered to 54 purposively selected built environment professionals in academics, consultancy and in government is the primary data collection instrument. This was supported by interview of government physical development regulators and property development companies. Secondary data were obtained from literature. Primary data were analysed using descriptive statistics and relative importance index while content analysis was used for qualitative data. The study found that while opportunities for adoption of green roofs exist, they were not popular in the study area because of cost, technical challenges, poor knowledge as well as limitations imposed by the interpretation of planning laws. The paper proposed context-relevant application of green roofs as a complement to ongoing green infrastructure programme in the study area.
