Environmental Issues

Mallorca's nature is beautiful — but fragile. The combination of 14+ million tourists annually, limited resources, and climate change poses existential challenges for the island.

Water Scarcity

Water is Mallorca's most critical resource. The island has no large rivers, groundwater levels have been declining for decades, and consumption — fueled by pools, golf courses, and general tourist demand — regularly exceeds natural regeneration. In the summer of 2023, a water emergency was threatened for the first time in years. The government has built desalination plants (the largest in Palma) but struggles with the high energy costs of this technology. Every tourist can help: take short showers, use towels multiple times, do not heat pools.

Overtourism

14 million tourists on an island with 920,000 inhabitants — the numbers don't always add up. In high summer, popular beaches (Es Trenc, Calas in the east) are hopelessly overcrowded, hiking trails in the Tramuntana are congested, rental prices in Palma are unaffordable for locals (because apartments are more lucrative as holiday rentals), and the infrastructure (roads, sewage treatment plants, waste disposal) is stretched to its limits. In 2023 and 2024, there were large anti-tourism demonstrations — a clear sign that the population feels a limit has been reached.

Coastal Development

The building sins of the 1960s–80s — concrete castles directly on the beach, concreted coastal sections, destroyed dune landscapes — are difficult to reverse. Some of the worst examples (Magaluf, S'Arenal, Can Picafort) have been redeveloped and upgraded for years, but the damage to the coastal landscape is partially irreversible. Since the 1990s, strict building regulations have been in place, and a hotel construction moratorium prevents further concreting.

The Eco-Tax (Impuesto de Turismo Sostenible)

Since 2016, tourists in the Balearics have been paying a tourist tax: 1–4 € per person per night (depending on the type of accommodation and season, halved in the off-season). The revenue (over 100 million euros per year) flows into the Sustainable Tourism Fund: conservation projects, beach restoration, hiking trail maintenance, cultural preservation, and water management. A model that has attracted international attention.

Sustainability Initiatives

The Balearics have set ambitious goals: by 2030, the share of renewable energies should rise to 35% (currently under 10%), single-use plastic has been banned since 2021, and the Posidonia seagrass meadows — crucial for clean coastal water and as CO2 storage — are under strict protection. Whether the goals are achieved depends on whether the balance between economic growth and nature conservation succeeds.
