Singapore is different compared to China or India because it has pretty high population density but acute shortage of land that can be used for farming. It is also a country that likes to plan ahead and have contingency measures to reduce dependencies/risk and actually has the political climate, knowledge and willingness to do what is necessary. I think it'll achieve great efficiency in this field.
singapore is my favourite example for ..pretty much everything. they are already doing great with indoor ag. and also shiok..for cell based seafood alternative. https://shiokmeats.com/
the only bad thing about singapore for me is the humidity. i struggle when i am outdoors in singapore. i cant handle it anymore. otherwise..my motto to other wannabe city states: be like singapore!
