Drone Lokossa — irrigated agriculture and Mono hydraulics
OHM WORKS works in Lokossa, the Mono capital, on multispectral mapping of irrigated perimeters, monitoring of hydraulic structures (dams, canals) and documentation of urban expansion zones. 2 h from Cotonou, the team mobilises within 72 h.

Why local
Water and land map together.
ANAC + public works
The Mono drains the Mono river basin and concentrates sensitive hydraulic structures (Nangbéto dam upstream, rice perimeters). We coordinate upstream with ANAC, the Hydraulics Directorate and the operators concerned.
2 h from our HQ
Lokossa is 110 km from Cotonou. For a one-off mission (hydraulic check, agricultural baseline), the team is on site within half a day. For seasonal agricultural missions, planning aligned to crop calendar.
Quote within 48 h
Quote priced within 48 h after brief. For multi-year agricultural monitoring programmes (3-5 passes per year), we offer a flat rate with seasonal calendar locked upstream.
Reading the rice landscape
The Mono is a strategic rice terroir for Benin. We read the landscape in terms of water management (canal levels, drainage, leaks), crop vigour (NDVI) and parcel structure — relevant for operators and agricultural finance institutions.

First mission in Lokossa?
Lokossa is a key development zone for Beninese rice farming. Our Okpara farm reference (200 ha SoNaMA LiDAR) attests to our agricultural expertise. Be our first public reference in the Mono.
Coverage in Lokossa and Mono
Mobilisation from Cotonou in 2 h. Our radius covers all of Mono (Lokossa, Comè, Athiémé, Bopa, Houéyogbé, Grand-Popo) and southern Couffo (Aplahoué, Dogbo, Klouékanmè). Multi-day missions can base in Lokossa or Comè.

Drone regulation in Lokossa
The Mono combines classic agricultural frames and hydraulic constraints (proximity of public works, flood zones). Every mission is preceded by an ANAC declaration. For flights over hydraulic structures, Hydraulics Directorate authorisation.
- ANAC Benin — Standard prior declaration, agricultural zone with limited constraints outside public-works areas.
- Hydraulic structures — Reinforced SORA if flying over dam, active irrigation canal or flood zone.
- Agricultural BVLOS — NOTAM for BVLOS multispectral mapping missions on large plots.
Frequently asked questions — local
Drone in Lokossa — your questions
What's the value of NDVI mapping on a rice paddy?
The NDVI map reveals — plot by plot — stress zones (water shortage, nitrogen deficiency, disease). You adjust fertilisation and irrigation to actual need — input savings around 30 %, yield improvement around 15 % on the value chains we monitor.
Can an active irrigation canal be mapped?
Yes, it's a typical case. Aerial photogrammetry of the linear, high-resolution DTM to verify slopes and levels, identification of leaks and erosion zones. XY < 3 cm, Z < 5 cm — sufficient for planning refurbishment works.
What lead time from Cotonou?
2 hours by road via the RN 1. For a one-off mission, the team is on site within half a day. For seasonal agricultural monitoring (3-5 passes per year), we lock a seasonal calendar and negotiate an annual flat rate.
Do you work with the Hydraulics Directorate?
Any mission over a public structure requires their agreement. Upstream we present a technical brief (flight profile, expected deliverables) which they approve. Our ANPT reference (Royal Palaces of Abomey) attests to our administrative rigour.
Deliverables for a multi-year agricultural project in Lokossa?
Plot-by-plot NDVI vigour map, differential fertilisation plan, statistical plant counting, growth tracking season after season, summary dashboard delivered to the farm manager. Everything georeferenced and GIS-exportable.
