BARCELONA, Spain (AP) — Spain granted personhood status Wednesday to what environmentalists call Europe's largest saltwater lagoon, which has suffered massive die-offs of marine life as it degrades due to coastal development and local farming. The new law came after a citizen-led push to provide better protection for the threatened ecosystem.

The initiative backed by more than 600,000 citizens will become law after Spain’s Senate in Madrid voted in favour of the proposal to grant the Mar Menor lagoon on Spain’s southeastern coast the status of personhood, the first time such a measure has been taken in Spain.

A total of 1,600 square kilometres (994 square miles) of the lagoon and the nearby Mediterranean coastline will now be legally represented by a group of caretakers made up of local officials, local citizens and scientists who work in the area. The grassroots group that pushed the measure hopes this will improve the ability to defend the lagoon from further degradation.

The World Wildlife Fund calls the Mar Menor Europe’s largest saltwater lagoon. It’s home to several species of fish, seahorses and the endangered European eel. The lagoon, which covers 135 square kilometres (84 square miles), is separated from the open sea by a thin strip of land 22 kilometres (13.7 miles) long that is a popular vacation spot dotted with hotels.

For years, ecologists and citizens have denounced the periodic die-offs of marine life in the lagoon due to the runoff of fertilizers from nearby farms.

In 2019, over 50,000 people marched in the nearby city of Cartagena to denounce the degradation of the lagoon. This month, Spain’s government approved 20 million euros (US$19.7 million) in aid to improve water treatment in towns near the Mar Menor as part of a recovery plan for the lagoon.

“So that natural disasters like those that have occurred, so that the episodes of mortality of fauna of the Mar Menor don’t return, let’s give this ecosystem its own rights,” Sen. María Moreno said before the vote.

The law codifies the lagoon’s right “to exist as an ecosystem and to evolve naturally” and recognizes its right to protection, conservation and restoration.

In 2017, New Zealand passed a groundbreaking law granting personhood status to the Whanganui River.

The law codifies the Mar Menor’s right “to exist as an ecosystem and to evolve naturally” and recognizes its right to protection, conservation and restoration.
