I just came back from from a national (US) conference of smart-growth/ anti-sprawl activitists. The conference represented a very broad coalition of organizations working on city issues - from anti-sprawl, to affordable housing, to transportation.
It inspired me/ made me wonder about what kind of coalition we can cobble together to create a citizens' forum to envision the future of metro manila. I need to get a clearer picture of what organizations actually work on urban related issues in Manila. Off the top of my head, I can only recall advocates for the urban poor (which represent housing advocacy), but don't know of any that talk about transport issues or density and development.
