Local Produce- 100 Mile Diet in Singapore?

I have been reading This Organic Life, by Joan Dye Gussow. I have enjoyed reading about her committment to growing as much of her own food as possible and eating local. I am also aware of the 100 Mile Diet and the challenge posed to do a 100 mile Thanksgiving. Well, a carve out first, we would not be able to have turkey in Singapore if I followed the 100 mile diet challenge. But, it is an interesting thought.

Living on the island of Singapore, I would assume that upwards of 90% of the food is imported. Very little if any true agriculture exists in Singapore anymore. I wonder if I could do a 100 Mile diet. What is local? What is seasonal? What are seasonal veggies in the tropics? Would it be possible to supplement my own food by growing some on my new patio?

When we move in a month we will be blessed with a 15X15 foot patio. I spent the weekend dreaming of a container garden, small but still there. Perhaps some eggplant, peppers and some "greens". A papaya tree we have been told will fruit in 3 months if properly tended and it can be potted. Same with a bananna tree. So over the next few weeks I think I am going to do some research and find out more about eating local. I may need to expand my 100 miles a bit broader based on the simple fact that Singapore doesn't grow its own food, but I would assume I can get most of my "food" within a 200 miles. I need to find out local sources, I need to find out what can and is produced in the area... but it might be an interested idea.
