Strategic decision-support tools

Tools to decide, powered by MAELIA.

We design interfaces that make modelling accessible: building and running scenarios, comparing pathways, mapping results and producing charts and maps.

Our interfaces

Three interfaces for three decision scales.

Local authorities · value chains · technical institutes · government services

MAEDIAG France

Assess the vulnerability of crops and grasslands to climate change across France: yields simulated under three possible future climates for the 2030 and 2050 horizons, differences from the current climate mapped by department, small agricultural region or 8 km grid cell, and effects on working time, irrigation, nitrate leaching and GHG emissions.

Local authorities · agricultural advisors · consultancies · value chains

MAEDIAG Territoire

Build and compare agroecological transition scenarios across a territory: simulation plans under several climates, effects on yields, margins, water, nitrogen, greenhouse gases and soil carbon, field-by-field maps and sensitivity analysis.

Agricultural advisors · consultancies

MAEDIAG Exploitation

Diagnose a farm's climate vulnerability (water stress, heat stress, frost) and test adaptation scenarios (irrigation, cropping plan, technical itineraries, livestock) to simulate their effects on production, economics, water, soil and environment, from the MAELIA platform's outputs.

What our interfaces enable

From data to decision.

1. Describe

Know the territory

Crop rotations, soils, farms, water, climate, prices and costs: input data analysed before any simulation.

2. Build

Design a scenario

Change fields, rotations, technical itineraries, cover crops and livestock to build agroecological scenarios.

3. Simulate

Run a simulation plan

Combine scenarios, future climates and periods, with biophysical models calibrated on local data.

4. Compare

Compare pathways

Set several scenarios and their indicators side by side, over the same horizon and under several climates.

5. Map

Map the results

Visualise results across your territory at a glance, from the field to the 8 km grid cell.

6. Report

Produce deliverables

Generate clear, quantified summaries, charts and maps, and shareable showcases, ready for consultation and public decision-making.
