Cargo Drones for Conservation

Hi Fellow WildLabs Members:

Does anyone have experience or knowledge regarding using freight or cargo drones for conservation? We're Involved in a conservation project in Zambia and are wondering if cargo drones might be used to transport materials to avoid bad road conditions and other rural travel barriers. We might find that drones are not the most optimal tool for this problem, but we are exploring different ideas at the moment and would appreciate any insight. 

Thank you, Rosemary
