As urban populations continue to grow, producing food locally has become an important goal. Urban agriculture offers solutions, with two popular methods being vertical farming and rooftop gardens. Each method uses city space differently to grow fresh produce.
Vertical farming is a technique where plants are grown indoors in stacked layers. This approach maximizes production in a small area. Since it is indoors, it is not affected by outside weather. Instead, it uses artificial light and a controlled environment to help plants grow all year. This high-tech method requires significant energy for lighting and climate systems.
In contrast, rooftop gardens use the open, unused spaces on top of buildings. These gardens depend on natural sunlight and are exposed to local weather conditions. While they do not produce as much food per square meter as vertical farms, they are a more natural system. Rooftop gardens also provide green spaces in cities and can help with building insulation. Both methods show innovative ways to bring agriculture into urban centers.
