I read the interesting articles by East Coast Life. With today society were many older workers got difficulties in finding meaningful jobs.
It is a good idea to develop intensive farming.
Some of them maybe sent to Japan for intensive training. As Japan had the most well paid cleaners, why not Singapore had the most technological advance farming technicians or farms in the world.
The farm should locate near the biopolis or West Coast as most of the biodiversity scientists and higher institutions are there. Singapore had the advantage of having lots of land near the sea.
With the $15 billions biopolis nearby, the chance of breakthrough and export some of the cultivations is very high.
Thailand had successful built their prawn farms. Which I found very tasty. Japan able to grow water melons that sell many times the values of normal water melons. This are some example of the benefit of intensive farming.
So Singapore can diversified it food sources and not so dependent on other countries for its food.
As more careers were created in the outskirts areas, so it will lessen the congestions in the city area.
More natural pastimes were built for healthier living.
I think this idea is worth serious considerations.
