Agriculture is one of the most crucial elements for the sustainability of human civilization. It has been forecast that agricultural consumption would increase by 69% from 2010 to 2050 due to an increase in population. The current technological trends in agricultural practices are not suitable for small landholdings that are the norm in developing countries. As such, meeting future food demands seems like an uphill task for such countries. To stay sustainable, maximize productivity, and optimize land spaces, the concepts of advanced farming techniques need to be explored and integrated into agriculture. One such concept is drones with data-gathering equipment for agriculture which is now known as precision agriculture. How drones can be used? In precision agriculture, drones have a range of uses from soil and crop field analysis to planting and pesticide spraying. Drones can be used with different imaging technologies like hyperspectral, multispectral, thermal, etc. that can provide the farmers with time and site-specific information regarding crop health, fungal infections, growth bottlenecks, etc. Drones can also identify drier regions in a field and measures can then be taken to irrigate such regions with better techniques. Precision agriculture provides farmers with such concrete information that enables them to make informed decisions and utilize their resources more efficiently.
