Description :
This Radio País emission, produced within the European project Réseau Tramontana co-funded by the European Union, is a debate on water management in South-West France, particularly in the Gascogne and Adour basin. The discussion highlights tensions between agriculture, environmental sustainability, and competing uses of water, framed as a broader European question about governance and resource ownership.
The speakers focus on irrigation agriculture—especially intensive maize production—as the dominant consumer of water, arguing that farming accounts for the vast majority of withdrawals and that irrigation practices often exacerbate seasonal scarcity. They describe how water abstraction during dry summer periods leads to ecological stress downstream, affecting fisheries, river ecosystems, and coastal productivity. The debate also critiques the way water is measured and regulated mainly in terms of flow, rather than broader ecological cycles or soil health.
Finally, the conversation expands to structural issues: dam construction, water rights, data reliability, and political inertia in water infrastructure planning. The speakers question long-standing projects and highlight contradictions in policy, including inefficient storage strategies, weak enforcement of quotas, and the social consequences of intensive agriculture. They conclude by calling for a rethinking of agricultural models, emphasizing soil organic matter, recycling of nutrients, and a more integrated approach between society, agriculture, and ecosystems.
