What are the impacts, positive or negative, of rooftop gardens in urban areas and should they be launched? The investigation is being launched to determine the true impacts of rooftop gardens on the surrounding or involved communities as well as the environment itself. Through this investigation, the effectiveness of rooftop gardens, their costs and benefits as well as their sustainability (short or long term) will be assessed. A roof garden is any garden established on the roof of a building. These gardens are visually appealing as well as a means of controlling overall heat absorption, a means of providing food (if a vegetable garden), architectural enhancement, and recreational opportunities. Growing food in these gardens is known as “rooftop farming”. Green spaces in cities are used as methods to improve the quality of life of residents – they have been implemented to serve as a space for relaxation and to create an urban expanse. more aesthetic. On a smaller scale, the ability to grow rooftop crops is becoming increasingly popular around the world and could provide a potential source of food for urban communities. More vegetation can lead to an increase in biodiversity and allow ecosystems to thrive where they were previously removed or destroyed to make way for concrete jungles. There are many monuments from ancient history that involve rooftop gardens and the exploitation of these gardens, for example. , the medieval Egyptian town of Fustat, which had many high-rise buildings topped with rooftop gardens, as well as ox-driven waterwheels for irrigation. Urban rooftop gardening is practiced, as far as South Africa is concerned, in the cities of Cape Town, Johannesburg, Pretoria and ...... amidst ...... paper sources. – Bishop Desmond Tutu, 2009. Limitations and Improvements The limitations encountered in this investigation were the inability to determine correct figures or raw data on the real differences that rooftop gardens make in regulating and reducing temperature and energy costs. Thus, the evidence and conclusions rely more on the social impacts and general impacts of rooftop gardens that have been recorded all over the world. Possible improvements to the investigation could be to explore the versatility of green spaces such as vertical greenery (green walls) or urban parks like Green Point Park in Cape Town for example. Including primary research through a questionnaire involving the communities while getting their personal input could benefit the investigation and prove or disprove the hypothesis from a different point of view..
