How are people reacting to knowledge of Jakarta being the fastest sinking city in the world? How does it affect property prices?

What a great question @Risanti Delphia! I think you can even open a new forum thread in the eco-journey category about this! I'm not aware of any organization that focuses on that topic yet, bur there is this app Sejalan and they have an initiative called #NitipBelanja. They help traditional market vendors sell on their app :)
