The number of people living in cities around the world is rising quickly. Urban food supply systems are under tremendous pressure due to increased urbanization, which is also creating issues including a sharp decline in green space and an increase in heat island effects in cities. Vegetable farming on rooftops can absorb carbon and noise, lower air temperatures on the roof and in the surrounding area, and diminish the impact of the urban heat island. Certain urban rooftop gardens employ mineral insecticides and fertilizers. Scientists have shown that compost can act as a nutrition source in place of mineral fertilizers. In addition, it can raise soil moisture content, decrease soil erosion, and manage pests, weeds, and illnesses. Given that kitchen garbage is a frequent household item in metropolitan settings, composted kitchen waste can be a beneficial addition to rooftop vegetable gardens. Rooftop gardening is a relatively new concept in Bangladesh. Understanding rooftop gardening and conducting further study on rooftop gardens would be aided by this review work.
