Well-funded researchers from the global north often initiate short-term projects in southern countries without seeking substantive local input or expertise. This ‘parachute’ approach has to change, say four researchers who explore how to conduct equitable collaborations. Lingering aspects of colonialism need to end, whether it’s extracting indigenous knowledge or scientific resources such as fossils. Projects need to be reciprocal, mutually beneficial engagements and start with intellectual exchange or idea development. “Inviting someone just because they are from the global south is worse than not inviting them at all,” says climate scientist Minal Pathak. “It’s insulting.”
