Protecting aquifers
Tunisia’s coastal aquifers turn saline when abstraction outpaces recharge. Reducing pumped volumes without losing yield is the only sustainable path, and it is measurable meter in hand.
Impact
Results measured, field by field
Every figure on this page comes from a monitored farm: an olive grove in Sfax, a cereal cooperative in Béja, a citrus orchard in Nabeul.
Methodology
The cycle behind these figures
Four steps, repeated all season long: what is measured is compared against what was recommended.
Field data collection
Sentinel-2 images every five days, soil moisture sensors, on-demand drone flights and local weather data, aggregated field by field.
ContinuousAI-driven analysis
Our models, trained on Mediterranean time series, segment stress zones and detect diseases and deficiencies before they become visible.
Within 24 hTailored recommendations
A dated, quantified instruction per zone — irrigation rate, variable-rate nitrogen, treatment window — sent by email, SMS or WhatsApp.
Every weekContinuous crop monitoring
Every satellite pass measures the effect of the intervention. Field history feeds the model, which is retrained each season.

What the farm gains
Decide on data
Every recommendation rests on a dated, located measurement, available in the field history.
Save resources
Water, fertiliser and fuel applied where the field needs them, and only there.
Increase productivity
Spotting an underperforming zone early still leaves time to recover the season's yield.
Sustainable farming
Fewer inputs per hectare and exportable traceability for certifications and buyers.
Environmental footprint
What the farm gives back to its environment
In the Mediterranean, the limiting resource is not land, it is water. Every cubic metre saved on a field is a cubic metre left in the aquifer, and every sprayer pass avoided is fuel, time and chemical pressure removed.

Estimated from avoided doses
The figures below are averages recorded on farms monitored for at least two seasons, compared with their own baseline before monitoring.
Sparing the soil
Fewer machinery passes means less compaction, and therefore better infiltration the following winter. Adjusted fertilisation also limits the excess nitrate that leaches below the root zone.
Adapting to the climate
Intervention windows shift from one year to the next. A field’s multi-year history gives an objective basis for adjusting dates rather than repeating last year’s calendar.
Documenting sustainability
Every recommended dose and every recorded intervention stays time-stamped. Buyers and certification bodies ask for that traceability: it exports straight from the platform, with no re-keying.
Case studies
Three farms, three problems, three results
220 ha olive grove, Sfax
Olive (Chemlali)220 hectaresSfax, Tunisia
01 The challenge
Highly uneven yields from one block to the next with no clear explanation, and an irrigation bill up 18% over two seasons.
02 The solution
Full mapping of the estate, weekly NDVI monitoring, six soil moisture stations in the most heterogeneous sectors and a deficit irrigation schedule recalculated every week.
03 The results
- 28% of irrigation water saved over the season
- +12% average yield on monitored zones
- Two peacock spot outbreaks treated before spreading
Cereal cooperative, Béja
Durum wheat1,400 hectares38 membersBéja, Tunisia
01 The challenge
Uniform nitrogen applications across all fields, with no visibility on which zones were genuinely deficient or on the yield expected before harvest.
02 The solution
Variable-rate nitrogen maps generated from NDRE at tillering, distributed to members over WhatsApp, and per-field yield estimates a month before harvest.
03 The results
- 19% less nitrogen at equivalent yield
- Harvest planning brought forward by three weeks
- 38 farms on a single shared map
85 ha citrus orchard, Nabeul
Citrus (Maltaise)85 hectaresNabeul, Tunisia
01 The challenge
Progressive salinisation of the water table and unexplained yellowing on border rows, with fruit size losses recorded two seasons running.
02 The solution
Weekly NDVI and NDRE monitoring cross-referenced with eight conductivity probes, orchard zoning into four irrigation sectors, and targeted leaching only where salinity exceeded the threshold.
03 The results
- 21% of irrigation water saved over the season
- Salinity brought back below threshold in three sectors out of four
- Average fruit size back to 2022 levels
