Urban farming is the practice of growing, processing, and distributing food in or around urban areas. Unlike traditional rural farming, urban farming utilizes available spaces within cities—such as rooftops, vacant lots, and community gardens—to grow food, often using innovative methods like vertical farming and hydroponics to maximize efficiency. Urban farming addresses several global challenges, including food insecurity, sustainability, and climate change. When food is produced locally, the carbon footprint associated with transporting food from rural areas to cities is reduced.
