What are the steps taken by Singapore as it eyes a farming revolution to tackle climate change and growth of population?

Singapore is generally considered a very unlikely state for harbouring a farming revolution. However, the smallest Asian city-state aims to boost its own food production and hence rarely rely on imports for meeting the food needs of its 5.6 million people with its tiered fish-farms and vegetable plots on top of the office buildings. It aims to raise its food production from 10% to a figure of 30% by 2030 under its famous plan known as 30-by-30. The biggest challenge is space as only 1% of its land is dedicated to agriculture. Also, the production costs are much higher than rest of Southeast Asia. Recent years have seen a doubling of number of sky-farms.
