Through encounters with a hydrologist, a farmer, and citizens mobilized around the Marais Poitevin, the director helps us understand the effects—on biodiversity and the state of rivers—of substitution reservoirs, also known as megabassins. For several years, Anne-Morwenn, David, Patrick, Yann, and others have been fighting for fair water sharing and devising ways to convince as many people as possible that it is time to change the agricultural model.
Directed by Sophie Averty
