By recognising locusts through the smartphone's camera, the app will be able to identify the stage of the insect's growth and record its location through the phone's IP address. This information can then be accessed by the farmer so that they can use pesticides more accurately and to target the insects in the early stages of their lifespan, significantly reducing the amount of crop damage.

This targeted approach could also reduce pesticide residue levels, leading to increased food safety while maintaining food security, and reduce environmental pollution, protecting nearby water systems.
