pattern, especially when China has the world's largest population to
feed. So concerned urban planners are starting to note the
social and physical effects of diaspora(大移居)when replaced
rural communities are forced into the cities.
On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a longterm study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.
The concept is already practiced at grass roots level.Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It's common to see organic
“hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translates into practical benefits, such as safe, nutritious vegetables and a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there're fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit—all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are growing.
