A recent Travel + Leisure article features Cleveland as one of the world's most visionary cities. Advances in urban farming account for Cleveland's inclusion on the list.

The former Galleria at Erieview mall hosts one such project, "Gardens Under Glass." The mall's glass-covered atrium combined with a hydroponics system has created an ideal greenhouse setting. The spinach, lettuce, tomatoes and other vegetables harvested are sold at the mall's weekly farmers market.

The Travel + Leisure posting included other impressive projects from around the world, notably Masdar City in Abu Dhabi, which "promises to be the world's most sustainable urban locale" upon its completion in 2020. Seoul's multilevel, solar-powered Paik Nam June Media Bridge, which features gardens, a library, a museum, and stores, topped the list. The article also highlights cutting-edge public housing projects in Paris, the "ideal public transport system" of Curitiba, Brazil, and the massive bike-share program of Hangzhou, China.

The list also offers a look into possible cities of the future, including the SeaScraper, which "would be anchored in areas with strong oceanic currents to power underwater turbines and provide endless free energy." A desalination plant would supply drinking water, and the SeaScraper would disperse nutrient-packed water to promote phytoplankton growth, ideally creating a reeflike environment that would attract fish.
