Urban farming involves growing food in cities, maximizing limited space with techniques like vertical gardens, hydroponics, and rooftop farms. It promotes sustainability, reduces food miles, and enhances community resilience. Common crops include vegetables, herbs, and microgreens, often cultivated in backyards, balconies, or vacant lots. Urban farmers face challenges like soil contamination, zoning laws, and water access but benefit from local demand for fresh produce. Community gardens foster social bonds and education. Technologies like automated irrigation and LED grow lights boost efficiency. Urban agriculture supports food security, greener cities, and healthier diets, with initiatives like farmers' markets connecting growers to consumers.
