The greening of Singapore started with the rapid planting of trees for a sea of green to permeate the island city. Pragmatism gradually gave way to purposeful strategies – high visibility areas such as the airport and the expressway leading from the airport to the city were adorned with bougainvillea, adding colour to greenery. After almost five decades, the country has retained its Garden City reputation. Some have attributed the success of the Garden City policy to Singapore's strong system of governance 1 and its principles of governance. 2 Many wonder about the mysterious interaction between political vision and policy implementation. At each phase of Singapore's development, through planned and unplanned occurrences, its leaders and public officers were learning from one another the meaning of sustainable urban governance.
