In Mexico, Lavery and James faced a more immediate challenge: how can you test GM mosquitoes in the field without exploiting people in a poor community? How do you make sure they’re properly informed? [...] They held numerous meetings with the community, hired an anthropologist, and spent two years in consultations to buy land for the giant mosquito cages, a process required by local law. They spent time, with local translators in tow, getting to know farmers and nurses. They call it community engagement.
