As Locusts Swarmed East Africa, This Tech Helped Squash Them

“Saying ‘Oh, there’s locusts in northern Kenya’ doesn’t assist in any respect,” Mr. Cressman mentioned. “We want longitude and latitude coordinates in actual time.”

Slightly than attempt to rewrite the locust-tracking software program for newer tablets, Mr. Cressman thought it might be extra environment friendly to create a easy smartphone app that may permit anybody to gather knowledge like an knowledgeable. He reached out to Dr. Hughes, who had already created the same cellular instrument with the Meals and Agriculture Group to trace a devastating crop pest, the autumn armyworm, by way of PlantVillage, which he based.

PlantVillage’s app makes use of synthetic intelligence and machine studying to assist farmers in 60 nations, primarily in Africa, diagnose issues of their fields. Borrowing from this blueprint, Dr. Hughes and his colleagues accomplished the brand new app, eLocust3m, in only a month.

Not like the earlier tablet-based program, anybody with a smartphone can use eLocust3m. The app presents pictures of locusts at completely different phases of their life cycles, which helps customers diagnose what they see within the discipline. GPS coordinates are routinely recorded and algorithms double verify pictures submitted with every entry. Garmin Worldwide additionally helped with one other program that labored on satellite-transmitting units.

“The app is very easy to make use of,” mentioned Ms. Jeptoo of PlantVillage. Final yr, she recruited and skilled locust trackers in 4 hard-hit Kenyan areas. “We had scouts who have been 40- to 50-year-old elders, and even they have been ready to make use of it.”

Within the final yr, greater than 240,000 locust records have poured in from East Africa, collected by PlantVillage scouts, government-trained personnel and residents. However that was solely step one. Nations subsequent wanted to behave on the info in a scientific method to quash locusts. Within the first few months, nonetheless, officers have been strategizing “on the again of envelopes,” Mr. Cressman mentioned, and the complete area had simply 4 planes for spraying pesticides.

When Batian Craig, director of 51 Levels, a safety and logistics firm centered on defending wildlife, noticed Mr. Cressman quoted in a information story about locusts, he realized he might assist.
