Doñana is back at the centre of a major environmental battle after Spanish prosecutors moved to force action over illegal groundwater extraction in and around one of Europe’s most fragile wetland areas. The case has renewed pressure on Madrid to do more than close illegal wells and instead make those responsible help repair the damage already done.
The legal challenge focuses on 250 operators identified in 2022 and 2023 for allegedly extracting groundwater without authorisation. Most were in Huelva, but cases were also detected in Sevilla and Cádiz, underlining how wide the problem has become around the Doñana area. RTVE reported that the breakdown was 198 in Huelva, 51 in Sevilla and one in Cádiz.
A court fight over who must act
At the heart of the dispute is a simple question with big consequences: who is responsible for launching environmental liability proceedings? Prosecutors from the Audiencia Nacional say the Ministry for Ecological Transition must begin the process and require measures to prevent further harm and repair existing damage. The ministry previously rejected that step, arguing that the matter falls mainly under the Junta de Andalucía because the problem affects not only water resources but the wider natural space.
That disagreement has now landed before the courts. Prosecutors argue that the ministry cannot step back from a case involving serious harm to protected waters and ecosystems, especially given Doñana’s long-running ecological decline and Spain’s wider obligations under environmental law.
Why this matters beyond another row over wells
This is not just another administrative clash. Doñana is one of Europe’s most important wetland ecosystems, internationally recognised for its biodiversity and vital for migratory birds, marshland habitats and protected species. When groundwater is extracted illegally and faster than it can be replenished, the damage does not stay underground. It reaches lagoons, marshes, forests and the wider balance of the park.
That is why WWF has backed the prosecutors’ move. The organisation says those who benefited from illegal extraction should also bear the cost of restoring the aquifer and damaged ecosystems, rather than leaving the burden to the public. It argues that legal action of this kind could finally send a stronger message that exploiting Doñana’s water reserves is no longer a low-risk, high-profit activity.
The shadow of Europe still hangs over Doñana
This latest push does not come in isolation. The Court of Justice of the European Union ruled in 2021 that Spain had failed to properly protect Doñana, particularly over groundwater depletion linked to agriculture. That judgment has continued to shape the debate ever since, and prosecutors are now explicitly linking the current inaction to a problem that has already triggered European condemnation.
Doñana has become one of the clearest symbols of the clash between economic activity and environmental limits in southern Spain. For years, campaigners have warned that the aquifer feeding the park has been under relentless pressure, driven above all by intensive farming and illegal boreholes. WWF has previously said more than 1,000 illegal wells and thousands of hectares of unlawful crops have affected the wider Doñana area over the years.
The government says it is acting
The Ministry for Ecological Transition insists it is working within its powers. According to responses reported by Europa Press and EFEverde, the government says the Guadalquivir river basin authority is closing illegal wells where appropriate, but argues it does not have the power to seal off farms, which falls to other administrations. It has also been said that the aim is to reduce illegal wells to zero.
That defence may satisfy neither prosecutors nor environmental groups. Their view is that shutting wells, while necessary, is not the same as opening a full environmental liability process that forces restoration and deters future abuse. In other words, the fight is no longer only about stopping the next illegal extraction. It is also about who pays for the damage already done.
A test case for Spain’s environmental credibility
What happens next matters far beyond Huelva. If the courts side with prosecutors, the case could become a landmark in how Spain handles environmental damage tied to illegal resource use. It would also test whether authorities are willing to move from patching over the problem to making polluters restore what has been lost.
For Doñana, that shift cannot come soon enough. The park has spent years as a warning sign for what happens when ecological pressure, weak enforcement and political hesitation collide. This latest case may now decide whether Spain is finally ready to treat that warning as a turning point rather than a recurring headline.
