In Martinique, discussions about food often focus on the cost of living, local production, or dependence on imports. However, food is also an issue related to ecological transition, public health, the local economy, and land-use planning. A study published by ADEME sheds some interesting light on this approach.
For the first time, it measures the concrete effects of Territorial Food Projects (PATs)—initiatives led by local governments to bring together producers, consumers, and local stakeholders. While the results pertain to five regions in mainland France, they offer several insights that could inform discussions in Martinique.
A food policy that extends far beyond agriculture
Established in 2014, the PATs aim to develop a regional food strategy. They bring together local governments, farmers, institutional food service providers, nonprofit organizations, and other local stakeholders around a common goal: to promote more sustainable food systems while addressing economic, social, and environmental challenges.
In April 2026, France had 444 Local Food Projects, illustrating the rise of this approach in recent years.
Above all, the ADEME study shows that food policy can have effects that go far beyond what’s on our plates.
Agriculture, Climate, Economy: Results Already Visible
The five PATs studied provided 829 hectares of farmland, including 266 hectares of organically farmed land, thereby helping to preserve farmland and encourage practices that are more respectful of the soil and water resources.
There is also an economic impact. By promoting the use of locally sourced food in school cafeterias, these regions have generated more than 7 million euros in economic benefits for their producers and food supply chains.
From an environmental standpoint, the results are just as significant. The actions taken have made it possible to avoid 1,132 metric tons of food waste in one year, representing nearly 11 million euros in savings, while reducing greenhouse gas emissions by approximately 6,171 metric tons of CO₂ equivalent by reducing food waste and diversifying protein sources in school cafeterias.
A food transition that also creates value
In addition to their environmental benefits, the study also highlights the economic benefits of Regional Food Initiatives.
According to the authors' estimates, Every euro invested in running a PAT could generate between 2.32 and 5.87 euros in local economic value, particularly through the purchase of agricultural products for school cafeterias.
The savings resulting from reduced food waste would be even greater, reaching between 8.3 and 16.7 euros for every euro invested in certain territories.
The study also suggests that widespread adoption of these practices could enable French school cafeterias to save between 200 and 450 million euros per year by reducing food waste. The authors note, however, that this is a theoretical projection, based on an extrapolation of the results observed in the five regions studied, rather than on savings already achieved.
School Cafeterias at the Heart of the Transition
One of the key findings of the study concerns foodservice. Each year, the five regions studied serve nearly 31 million meals à 208,000 children, making cafeterias a powerful driver of change.
By prioritizing local, organic, and seasonal products while reducing waste, local governments simultaneously support producers, improve the nutritional quality of meals, and limit their environmental impact.
The authors also point out that these new eating habits may gradually influence family practices, even though this effect is more difficult to measure than the direct impacts observed in school cafeterias.
A Source of Inspiration for Martinique
This study does not cover the overseas territories, and its findings therefore cannot be directly applied to Martinique. The realities of the island—its insularity, dependence on imports, land-use constraints, and unique agricultural characteristics—remain different.
On the other hand, it shows that food policy can become a genuine tool for regional development. Beyond agricultural production, it can support the local economy, preserve land, improve the quality of meals served to children, reduce food waste, and contribute to the ecological transition.
For Martinique, where food resilience is becoming increasingly important, these initiatives serve as a reminder that a food strategy is not limited to simply producing more. It also involves better connecting agriculture, institutional food services, consumers, and local governments in order to strengthen the region in a sustainable way.
