The Canary Islands are grappling with a significant coastal erosion crisis, losing about 2.5 miles of coastline annually, according to SOS Costas Canarias. This alarming trend coincides with rising tensions among residents frustrated by the tourism boom, which they believe is unmanageable and detrimental to their livelihoods. Local regulations allow property developers to exploit land for hotels and holiday flats with minimal taxation, contributing to low average salaries and a housing crisis. Approximately 18% of land within 500 meters of the coast is developed, with some islands like Lanzarote and Gran Canaria exceeding 40%. The tourism sector occupies nearly 20% of the living space, compared to 4% on the Spanish mainland. Critics argue that local authorities fail to protect the islands' biodiversity, as essential resources like water become strained due to overdevelopment. The SOS Costas Canarias report calls for an immediate halt to new development plans, warning that continued construction not only destroys natural habitats but also increases the risk of flooding for about 80,000 residents. Legal experts highlight institutional failures in urban planning that prioritize speculation over public interest.
