Jakarta Flooding Case Studies & Expert Source Needed for Documentary

Documentary about Jakarta subsidence/sinking Hi everyone, I'm a student from New Zealand who wants to film a documentary in Jakarta about the subsidence/sinking/flooding. I'm planning to visit and film in early April. I want to focus on filming about the communities/people affected by this and the visible government responses (such as the Muara Baru seawall). I do also want to try and interview at least one expert though who can give insight into the government's response and the broader situation. A couple of questions: Which areas would people recommend that I should film in to see the issue first hand, and to meet and speak to people affected by this? Muara Baru seems to be the place with a lot of focus on it, so I plan to film there. But are there other areas that people would recommend, as I understand that it is a pretty large area of North Jakarta that is affected. Also any advice on finding a guide/local who could help show me around these areas? I cannot speak any Indonesian so I want someone with good English who can also help me speak to locals. Where should I look online to try and find someone who can help with this? Secondly, any advice on who I should try to interview and what is the best method of outreach? I only have one documentary previously with about 20,000 views which I filmed last year in Myanmar, so I don't have an established platform. So I'm wondering if people have any advice on who I would realistically be able to get to sit down with me for an interview who could give insight into this, as I don't work for some big media network. I'm thinking local University professors, but are there any specific people or other organisations/institutions that are more likely to speak to me? Thank you for any advice on this. I have done research myself about both of these questions, but I imagine many people on this reddit page can give me advice that I wouldn't find just by reading articles and studies. So I really appreciate any help.
