Rooftop farming is the practice of growing food on the rooftops of buildings, utilizing otherwise unused space in urban areas. This method can include a variety of crops, such as vegetables, herbs, and fruits, and often employs techniques like container gardening or hydroponics. Rooftop farms can help improve air quality, reduce urban heat, and promote biodiversity. These farms also contribute to local food production, reducing the need for transportation and lowering carbon footprints. Additionally, rooftop farming can provide fresh produce to city dwellers, enhancing food security and encouraging sustainable practices within communities.
