Multifaceted applicability of drones: A review

Technology is playing its part in globalization and the drone technology is such a technology with a usage ever increasing in a vast range of disciplines such as agriculture, health and military. Drones can provide real-time data on farms that enable farmers to make informed decisions regarding farm inputs usage. Also, they can be used to aerially deliver medical supplies like blood, vaccines, drugs, and laboratory test samples during health emergencies to remote areas in developing countries. Military drones also help in security and surveillance on the enemies' movements which then helps select for target killings. Though beneficial, drones can cause injuries and damages to people and properties if the user is not trained and if there is a component failure during flight. Drones could also be hijacked by an extremist and divert the payload for their self-interest. In this paper, the Strength, Weaknesses, Opportunities, and Threats analysis of the current developments of agricultural, medical, and military drones are presented.
