Beautiful post @anggreklestari :) Utilizing the rooftop for gardening and for other activities benefits the residents and occupants in the area. When surrounded by equally tall structures, the urban rooftop garden provides a scenic vista and an ideal escape from the hustle and bustle of the city when there's an absence of green open spaces.    

I remember a Filipino youtube channel I was watching some time ago called  [Don Bustamante Rooftop Gardening](https://www.youtube.com/channel/UC_mfYDDOF3U5mjFwEqfiklw), where he utilized his rooftop to plant vegetables for their own consumption here in the Philippines. His videos however are in the local language but it just shows that vegetables growing in tropical humid weather in the middle of the city is ideal.
