This paper evaluates vertical gardening as a potential solution to critical urban challenges such as climate change and food scarcity. It explores how vertical gardens can improve air quality, enhance energy efficiency, optimize the use of limited soil, and provide aesthetic benefits. This research highlights the contrasting outcomes of Singapore and Mexico City, which suggest that while vertical gardens offer significant advantages, their success heavily depends on technological and design factors, long-term government support, and meticulous management. Overall, it concludes that strategic planning and policy-making are needed to realize the complex goals of vertical gardening.
