When they get maps they can negotiate with the government. Most mineral and logging interests are extractive and very destructive. Indigenous people usually live on what has become government land. I believe we are a long way from coexistence. What most indigenous people do not have is a strong political organization.
Maps are like the point of the lance, the beginning of a process.
Indigenous people in most areas simply cannot do it alone. They need help. But, conservationists cannot do it alone either. What they should do is form alliances. These are exceptionally difficult to put together.
