Challenges & The Role of Rooftop Gardening for Urban Environmental Sustainability: A Focus on Rooftop Gardening in Banasree Residential Area

Abstract: This paper depicted the significant challenges and hindrances to promoting Green Roofs (Roof-Top gardening) along with the role of green roofs in urban environmental sustainability. Urban environmental sustainability will be the biggest challenge of next 21st century as it has already been estimated that by 2050, more than two-thirds of the world’s population will live in cities, up from about 54 percent today, along with the climate change impact. Rooftop gardening can reduce the climate change impact to a significant level. But there are many challenges and hindrances in promoting RTG in Bangladesh due to a lack of awareness, a lack of incentives, and a lack of other facilities. However, this paper reported a critical review of the existing body of knowledge of researchers related to rooftop gardening. These common themes are the concept of green roofs, the benefits of building with green roofs compared to conventional buildings, and various challenges to making green roofs. It is found that the existing studies have predominantly focused on the environmental aspect of green roofs. Other dimensions of the green roof, especially the challenges and current situation, are largely overlooked.
