- Architect's "Wonder Forest" concept would turn Beirut skyline green
- The plan involves installing 60,000 potted trees on the city's rooftops
- Benfits include improved air quality, reduced CO2 emissions and increased shade
The legendary Hanging Gardens of Babylon are the inspiration behind an ambitious plan to grow a rooftop forest high above Beirut's crowded streets.
The cityscape is currently overshadowed by concrete highrises, with parkland making up just 3% of Lebanon's capital, according to a study by the American University of Beirut.
The lack of greenery has contributed to poor air quality and trapped heat, among a host of other environmental issues, claims architect Wassim Melki. This led him to the the unconventional idea of greening over the city's rooftops.
"We want to cover the top of nearly every building in the city with trees," said Melki.
Challenging though it sounds, Melki's proposal does not involve complicated drainage systems or engineering.
"We're just talking about planting small to medium-sized trees in relatively large pots and securing them to the roofs," he added.
The 28-year-old architect claims there are 15,000 suitable rooftops -- around 80% of those in the city. "Even planting just one on each would result in as many trees as there are in New York's Central Park," he said.
