Urban farming addresses food security and sustainability in densely populated cities. Models such as rooftop gardens, vertical farms, and hydroponics utilize limited spaces to grow fresh produce. Rooftop gardens beautify urban landscapes while reducing heat islands. Vertical farming employs stacked layers, maximizing output with minimal land use. Hydroponics eliminates soil, using nutrient-rich water for efficient cultivation. Community-supported agriculture and urban allotments encourage local engagement, providing residents access to fresh, affordable produce. Urban farming also fosters environmental awareness and promotes circular economies by utilizing organic waste for compost. These innovative models redefine food production, bridging the gap between cities and agriculture.
