Turkiye

Türkiye enters the second half of this decade as one of the most-visited countries on earth, having welcomed roughly sixty-two million total visitors in 2024 — about fifty-three million foreign nationals alongside nearly ten million expatriate Turks — and earned a record sixty-one billion dollars in tourism receipts. Tourism is now the country's most reliable hard-currency engine, contributing close to twelve percent of GDP and supporting more than three million jobs. The trajectory looks triumphant on paper. Yet the physical, ecological and demographic foundations beneath that trajectory are deteriorating faster than the headline figures suggest, and the most realistic outlook for 2100 is not collapse but fundamental reorganization. The map, the calendar and the business model of Turkish tourism will all migrate over the coming three quarters of a century, even as the country likely retains a place among the world's leading destinations.

The starting point matters because the present model is highly concentrated. Istanbul alone received over a third of all foreign arrivals last year. Antalya hosted more than seventeen million visitors and remains, with its Aegean counterparts in Izmir, Çeşme, Bodrum and Kuşadası, the financial heart of an industry built around the all-inclusive resort. Package-tour spending rose by more than a fifth in 2024 to over seventeen billion dollars, anchored by Russian, German, British, Iranian and Bulgarian source markets. This is a portfolio with extraordinary volume but also acute geographic and seasonal exposure, and the same coast that makes it lucrative is the coast most vulnerable to what is coming.

Türkiye sits inside what climate scientists describe as a Mediterranean hotspot, where regional warming runs well above the global average. State meteorological projections envisage mean annual temperature increases on the order of one to six degrees Celsius by century's end, with the higher end concentrated in interior and southeastern Anatolia. Summer maxima along the coast are likely to climb several degrees, autumn precipitation to decline sharply, and Mediterranean bioclimatic conditions to expand across nearly the entire country. Wildfire, which the catastrophic 2021 season turned from cyclical risk to chronic feature, has already redrawn the southern coast: Manavgat lost roughly fifty-seven thousand hectares that year in the largest fire in the republic's history, Marmaris burned twice in successive seasons, and by 2024 fire activity was shifting further east into Diyarbakır. The wildland–urban interface is now almost coterminous with the southern resort belt.

Water is the slower but more decisive constraint. Lake Tuz, the country's second-largest lake, dried completely on satellite record for the first time in 2021. Groundwater in the surrounding Konya Closed Basin has dropped more than fourteen meters over a generation, with most of the loss concentrated in the last decade and driven by tens of thousands of wells supporting water-intensive crops. Istanbul's reservoirs collapsed to around thirty percent of capacity by September 2025 after a near-total rainfall deficit across parts of Thrace. Sea-level rise simultaneously threatens the Golden Horn frontage, the Bosphorus quays, low-lying infrastructure in Izmir Bay, and the long sandy beaches that anchor Antalya, Side, Belek and Bodrum, while salt-water intrusion advances into the coastal aquifers serving resort complexes.

Perhaps no single ecological story matters more than the Sea of Marmara, ringed by twenty-five million people and absorbing millions of cubic meters of daily wastewater. The 2021 mucilage event covered the surface from spring to early summer, devastating fisheries and tourism. The phenomenon returned in October 2024 in the Gulf of Erdek and spread across the entire Marmara within a month and a half, accompanied by sea-surface temperatures well above seasonal norms. Marmara fish biodiversity has fallen roughly a quarter and biomass about a fifth since 2021. The implications for Istanbul's waterfront experience, for cruise and yacht itineraries, and for the Princes' Islands as a summer escape are substantial.

Against this backdrop, artificial intelligence is settling in beneath Turkish tourism as ambient infrastructure rather than novelty. Istanbul Metropolitan Municipality has already piloted geolocation-driven flow management around Hagia Sophia and the Grand Bazaar, a template likely to extend to Topkapı, Ephesus and the Cappadocia balloon launch zones over the next decade. Resort-level optimization of energy and water consumption is becoming existential rather than optional in the Marmara basin. Heritage digital twins, machine-vision monitoring of Cappadocia's tuff stability, AI-assisted restoration of monuments damaged in the 2023 Kahramanmaraş earthquakes, and wildfire prediction systems combining satellite thermal data with vegetation moisture and wind models all represent high-leverage applications. The same tools, however, carry real costs: recommendation algorithms tend to entrench the very concentration they claim to relieve, labor displacement threatens a workforce heavily composed of young, gendered and migrant employees, and hyperscale data centers carry water and energy footprints that risk worsening the crises adaptive AI is meant to solve. The Kartalkaya hotel fire of early 2025 served as a reminder that regulatory governance has not kept pace with technology adoption.

The 2023 earthquakes themselves underscored how exposed Turkish heritage is to compound shocks. The Kahramanmaraş sequence killed more than fifty thousand people, damaged or destroyed over three hundred thousand buildings, and inflicted economic damage equivalent to roughly a tenth of national GDP. Nearly half of the region's historical structures were damaged. Critically, Göbekli Tepe, Karahan Tepe, the Şanlıurfa museums, Diyarbakır's Ulu Cami, Mardin and Nemrut Dağı emerged largely undamaged, preserving the southeastern Anatolian heritage circuit as the country's most distinctive global archaeological brand and a viable growth axis. The Istanbul fault, however, remains the single largest tail risk to Turkish tourism through 2100.

The regional picture by century's end is therefore one of pronounced redistribution. Istanbul will remain the country's tourism anchor, secured by its position as a top-three global aviation hub, even as its waterfront contends with sea-level rise and Marmara ecological stress. The Mediterranean Riviera is the segment under greatest pressure: July and August will likely become effectively unmarketable in much of the southern coast for European leisure travelers, with the high season compressing into May–June and September–October. The Aegean is structurally more resilient, with cooler maritime winds, deep cultural anchoring at Ephesus, Pergamon, Aphrodisias and Bodrum, and a maturing food and yachting economy that positions it as Türkiye's premier coastal segment. Cappadocia retains its long-term outlook despite balloon-operation constraints and the need for visitor-flow caps to protect eroding tuff formations. The Black Sea region — Trabzon, Rize, Artvin, the Kaçkar yaylas and Sümela — emerges as the clearest climate winner, with summer temperatures well below the southern coast and growing Gulf and domestic demand for highland escape. Eastern and Southeastern Anatolia — Lake Van, Mount Ararat, Kars and Ani in the east; Mardin, Şanlıurfa, Göbekli Tepe, Diyarbakır and Hasankeyf in the southeast — form the most plausible growth frontier, provided reconstruction holds and political conditions allow tourism to develop with local benefit.

The most defensible description of Turkish tourism in 2100 is not a number but a portrait. It will be more inland, more highland, more shoulder-season, more culturally anchored, more AI-mediated and more climate-disciplined than the all-inclusive Mediterranean package that defines the country today. The country will earn roughly the same global rank, but from a significantly reorganized portfolio, with adaptation investment in water, wastewater, fire suppression, heritage stabilization and coastal protection determining which destinations thrive and which fade. Volume will not collapse — Türkiye's location, infrastructure, cultural depth and aviation centrality are too durable for that — but the industry that emerges will be recognizably different from the one that just set its records.
