Tourism

Ocean-related tourism and recreation supports more than 320,000 jobs and US$13.5 billion in goods and services in Florida. But a swim in the ocean became much less attractive in the summer of 2023, when the water temperatures off Miami reached as high as 101 degrees Fahrenheit (37.8 Celsius). The future of some jobs and businesses across the ocean economy have also become less secure as the ocean warms and damage from storms, sea-level rise and marine heat waves increases. Ocean temperatures have been heating up over the past century, and hitting record highs for much of the past year, driven primarily by the rise in greenhouse gas emissions from burning fossil fuels. Scientists estimate that more than 90% of the excess heat produced by human activities has been taken up by the ocean. That warming, hidden for years in data of interest only to oceanographers, is now having profound consequences for coastal economies around the world. Understanding the role of the ocean in th...

The Caribbean’s sandy beaches, clear turquoise water and vibrant coral reefs filled with an amazing variety of sea creatures have long been the pride of the islands. The big three – sun, sea and sand – have made this tropical paradise the most tourism-reliant region in the world. But now, all of that is under threat. The explosive growth of a type of seaweed called sargassum is wreaking havoc on economies, coastal environments and human health across the islands. I study the intersection of critical infrastructure and disasters, particularly in the Caribbean. The sargassum invasion has worsened since it exploded in the region in 2011. Forecasts and the seaweed already washing up suggest that 2024 will be another alarming year. Sargassum levels were already high around many eastern Caribbean islands in late May 2024. Forecasters expect increasing sargassum washing up in June on many of the islands and in the Gulf of M...

In the popular imagination, the Caribbean is paradise, an exotic place to escape to. But behind the images of balmy beaches and lush hotel grounds lies a crisis, the likes of which its residents have never experienced. Caribbean islands are in a water crisis, and their governments have warned that water scarcity may become the new norm. Within the past five years, every island in the region has experienced some sort of water scarcity. For example, Trinidad is experiencing its worst drought in recent memory, and residents are under water restrictions through at least the end of June 2024, with fines for anyone who violates the rules. Dominica, considered the nature island of the Caribbean for its mountain rain forests, is seeing a significant decrease in freshwater resources and increasingly frequent water shortages. In Grenada, known as the spice isle, drought has affected water systems throughout the island. Apartments in Havana, Cuba,...

Spring is go time for climbers who hope to summit Mount Everest, Earth’s highest peak above sea level. Hundreds of mountaineers from around the world travel to Asia in April and May, headed for base camps in Nepal and Tibet. But jagged peaks won’t be the only thing they see. Especially on Everest’s more heavily traversed Nepal side, they’ll find fields of garbage – including cans, bottles, plastic and human and animal excrement. Each year, more than 60,000 trekkers and climbers visit the Sagarmatha National Park and Buffer Zone, a high-altitude swath of the Khumbu region in northeast Nepal that includes Everest and seven other peaks. Some 400 to 500 climbers attempt to summit Everest every year. The trash problem first became evident in the 1980s and 1990s, when climbing on the mountain and trekking in Khumbu began to increase. Climber and trekker numbers have further skyrocketed in the past 20 years. Most coverage of this issue focuses on nega...

Wildfires destroyed the Hawaiian tourist town of Lahaina on Aug. 8 and 9, 2023, leaving many of its roughly 13,000 residents homeless. Fires also burned in other areas on Maui, Hawaii’s second-largest island, and its Big Island. President Joe Biden issued a disaster declaration on Aug. 10, which authorizes federal aid for communities in harm’s way. The Conversation asked Ivis García, an urban planner who has researched disaster recovery efforts in Puerto Rico, to explain how the U.S. government responds to disasters like these and how Maui’s geography could interfere with aid delivery. Is it harder for aid to reach an island than the US mainland? The Federal Emergency Management Agency, which delivers emergency assistance after disasters, has to deal with big transportation challenges in cases like this. Initially, FEMA will be focused on bringing food, generators, cots, meals and anything else people need, and that aid will be arriving on planes and boat...
