Know when
swarms get close.
AcreScope maps locust swarms in real time and reads the environment around your fields, so you can act before they arrive.

When rains and warmth align, solitary insects gather, breed, and form swarms that darken the sky. They cross borders in hours and strip fields in minutes, threatening the food security of one in ten people on earth.
Watch the swarm move.
Real-time sightings from the global network. Pan the map; the list follows. Prepare before they arrive.

Read the risk before it reads your fields
A combined risk score blends environmental signals with how close swarms actually are, so a number means something you can act on.
- Precipitation, soil moisture, vegetation & temperature
- Calibrated to the risk level you choose to act on
- Low / Moderate / High / Critical at a glance
Every sighting, near you, as it lands
Browse confirmed reports from official sources and the field community on one live map, sorted by distance, dated, and labelled by behaviour.
- Official FAO observations + community reports
- Filter by recency, distance and risk level
- Nearest sighting, always one tap away

Designed for clarity in the field, surfacing only the next thing you need to know.
From a sighting to a warning.
Data comes in
FAO field teams and the community report sightings, while satellites stream the environmental conditions around them. AcreScope is not affiliated with the FAO.
The model reads it
AcreScope weighs environmental signals against swarm proximity and global weather to estimate where risk is building.
You get the warning
When a swarm enters range of your fields, AcreScope tells you, early enough to do something about it.

Privacy by default
Reports are pseudonymous, tied to an install, never your name. You stay in control of location.
