Two degrees more by 2030, 2.7° in 2050 and up to 4° by 2100. This is the Reference Warming Trajectory for adaptation to climate change (Tracc) retained by the France. This is also the hypothesis integrated by Météo France to build the Climadiag agriculture application, a forecasting tool intended for farmers and those who advise them in their profession. “Without being climate specialists, these professionals need to be on the lookout for these issues”underlines Sophie Martinoni, director of climatology and climate services at Météo France.
A mesh size of 8 km by 8 km
Developed with the Solagro association and INRAE (National Research Institute for Agriculture and the Environment), the digital tool makes it possible to measure the impact of climate change on crops but also animals (pig, poultry, cattle) in a very precise manner. “The geographical grid has 10,000 points of 8 km by 8 km, with 250 ready-to-use indicators, specifies Nicolas Métayer, deputy director of Solagro. The objective is to help the agricultural world to put in place strategies to adapt in the long term, whereas in agriculture we often think in the very short term. »
This toolbox makes it possible, for example, to know, at the selected time horizons (2030, 2050, 2100), the number of hot days to be expected for a corn crop, the stages of development of soft wheat (emergence dates, ear one centimeter, flowering, maturity, etc.), soil water stress, risks linked to livestock, etc.
Four years after its launch, Climadiag agriculture already has some 4,000 users, in chambers of agriculture, design offices, management centers, etc. “Based on feedback, many appreciate the practical side, the fact of obtaining results in just a few clicks, and the fact that it is suitable for many sectors, including breeding. »
