I'm Edson Natha, from Mozambique I work for ministry of land environment and rural development. I have no experience or direct participation in the use of drones in agricultural activities but I have already had experience in other activities such as tourism to capture aerial images.
However I believe that something should be done in terms of legislation to use these devices in Mozambique in a legal way.
I recall a situation in which a team of Dutch researchers who were going to do a mapping was arrested by the authorities on the grounds that they were flying over a drone for unjustified purposes
