All this talk of a population of 6.9m (“worse-case scenario”, “projection” or “plan to dilute locals to 55% of the voting public”) reminded me of this BBC article
Today, there are only a handful of farms left, most of which are located in agrotechnology parks that take up less than 2% of Singapore’s total available land.
In recent years, the government has tried to diversify and secure Singapore’s food supplies, though much of its food still comes from nearby Malaysia and large producers such as China.
Singapore has been widening its use of contract farming and overseas food zones, where local buyers can control everything from production to processing.
Closer to home, in 2009 it set up a food fund worth 5m Singapore dollars (£2.6m; $4.1m) to support local farms and invest in research and development.
The government has also been trying to promote more creative methods of growing food, such as the urban farming projects similar to that run by Mr Ng, where residential or commercial areas can be used to grow fruit and vegetables.
