Urban farming blossoms in Hong Kong

In a city as densely populated as Hong Kong, living space is hard to come by, let alone space to grow plants and vegetables. But those keen to see a bit more green in this concrete jungle are now setting their sights high by creating roof top farms.

Elements of traditional farms are being brought to the roof tops of buildings in Hong Kong. This kind of farming is seen as a way to relieve stress and is also beneficial to the environment.

Osbert Lam, founder of city farm, said, "It is good for the whole city. For example, in this building, people are already paying less for electricity bills. As we put plants on the surface of the rooftop, it has created a big difference in temperature. The temperature difference in a place with and without shade is at least five to six degrees Celsius."

This 10,000 square foot roof top farm consists of 350 boxes that allow people to grow plants of their choosing. A monthly rent, ranging from $19 US dollars to $26 US dollars, is charged every month. A price that does not deter people's will to go green.

Tina Wu, city farm member, said, "It's making the city greener. The air is too polluted, and putting plants here helps to absorb the carbon dioxide. I think it's great."

But experts warn that roof top farming is not suitable for all buildings, as it may damage the surface. They say you must check the load bearing capacity, the maximum weight a structure can support, before putting any plants on it.
