Again, overlapping claims is a construct of colonization. Having said that, if the indigenous communities are not there yet, or not interested, then it's pretty hard to.... You can bring a horse to the trough, but you can't force it to drink.
If they are under-capacitated but interested in moving forward in a dialogue, I would encourage the committee to encourage the government to resource those communities so that they could have internal discussions, and let them decide among themselves whether conservation is something they want to do.
I know, based on my experience, that not every indigenous community wants to get into conservation. They see industrial development as a way forward. Then again, the concept of conservation economies is a new concept that indigenous communities are only now learning, so they still haven't put their heads around it. Not all indigenous communities have got their heads around the possibilities of using their traditional territories and creating economies of scale for themselves that are not dependent on industrial development.
