Urban agriculture, encompassing farming methods within urban and peri-urban areas, has gained significant attention as a viable strategy to address food insecurity, environmental degradation, and urban poverty. This research explores the multifaceted importance of urban agriculture, highlighting its social, environmental, economic, and health benefits. It further examines entrepreneurial opportunities and strategies to foster sustainable food systems through innovative practices such as backyard cultivation, participatory gardens, green roofs, vertical farms, and tech-enabled marketplaces. The study underscores the critical role of urban agriculture in enhancing food security, promoting economic resilience, and fostering environmental sustainability, especially in rapidly urbanizing regions like Asia and Africa. By integrating policy advocacy, public-private partnerships, and climate-adaptive technologies, urban agriculture presents a scalable model for addressing urban challenges while encouraging entrepreneurship. The findings advocate for a holistic approach that combines technical assistance, community engagement, and policy support to harness the full potential of urban agriculture as a cornerstone of sustainable urban development.
