Sharon in her blog suggested the benefits of having urban farms in terms of solving the urgency of food supply in cities.
I agree that the idea of “farm-to-table” is great when customers nowadays concern more on the food safety and freshness. Taking Shanghai and Hong Kong from the blog as example, unlike other places, these cities are suffering from the shortage of land. Having medium to large scale farmland may not be so feasible, but small rooftop and indoor gardens seem to be a nice idea to promote. However, I am afraid this scale of urban framing is not going to contribute to the urgency of food supply.
Still, in terms of sustainable development, I am very supportive in promoting urban farming without hesitation. People can easily grow vegetables no matter how few allotments they can afford to plant on the rooftop or even it is just several pots on balcony. It is also a very healthy hobby. People spend time taking care of the plants, after months they will be able to eat what they grew. I believe being a rewarding activity to gain satisfaction can attract more and more people to join and become urban farmer.
