Quintana Roo sargassum crisis causes $11.5 billion annual loss

The sargassum seaweed crisis in Quintana Roo is causing massive economic damage to the regional tourism industry. Estimates from the Inter-American Development Bank suggest annual losses of approximately $11.5 billion USD due to hotel cancellations, deferred reservations, and damage to the destination's international reputation. This figure represents roughly 17% of the state's Gross Domestic Product.

In addition to lost revenue, the cost of cleaning is substantial. Hotels in the tourist zone alone invest $150 million USD annually to remove algae from beaches. The 2026 season has seen record-breaking levels, with over 133,000 tons of seaweed removed by late September, significantly exceeding previous years.

To combat the phenomenon, the Mexican government, through the Navy, has implemented strategies involving containment barriers and collection vessels to intercept the seaweed at sea. Following a visit by President Claudia Sheinbaum, an extraordinary fund of 2 billion pesos was confirmed to address the emergency. The crisis has drawn international attention, with delegations from 30 countries visiting Cancun to study the state's containment infrastructure and real-time monitoring platforms.
