I would say that's a very rare occurrence, because we're usually looking at the same problem in a completely different way. It may seem as though we are saying different things, but I would say that the views are complementary in many cases.
Keep in mind that indigenous knowledge isn't limited to data or information. It's a way of doing things. We need to develop knowledge together, establish professional working relationships and figure out how to do our work as scientists. We can't forget that, because it's a road map of sorts for working together.
Nevertheless, when problems do arise, I think it's necessary to refocus on the governance and the purpose of the project, in order to determine what's important. When that question is put to the team of locals, indigenous people and other stakeholders around the table, they are able to work through it. They break down the differences and, in many cases, realize that the positions aren't as different as previously thought. I can't give you a specific example right now, but I can tell you that situations where this really creates a conflict are rare.
