Consider Cruise Ships


Dr Anjani Ganase asks us to reflect on what is gained or lost when cruise ships come ashore to our islands.

Do cruise ships add or take away from the Caribbean?
The cruise ship industry has boomed in the Caribbean over the last fifty years, transporting 500,000 passengers annually in the 1970s to over 20 million today. The increase in passengers corresponds to investments in engineering for bigger ships with better features and services. Over the years, cruise ships have increased in size at a rate of 90 feet every five years with the largest cruise ships today carrying over 6000 passengers. Cruise ships come with cinemas, sky diving simulators, rock climbing walls, wave riders and biking facilities along with the 24-hour all you can eat buffets on top of dining halls, bars and restaurants. It is more about the journey than the destinations!

The majority of visitors come from the USA and Europe, and the most popular destinations are the Bahamas, Mexico and St Maarten. There is no doubt that cruise liners turn over huge revenues with an average of 3.5 hours per visit to an island. Such short exposures hardly give any impression of an island before moving on to another. These momentary influxes of visitors to any island results in a lower spend compared to the visitor that flies in for a couple days. At some destinations, cruise ships avoid paying docking charges as governments give incentives to cruise liners to visit, but such enticements are not rewarding, especially as many passengers may not disembark.

What are some other costs of cruise ships?
With up to 6000 passengers enjoying luxury entertainment, it is no surprise that cruise ships produce an incredible amount of waste. In one week, a cruise ship carrying 3000 persons produces about 210,000 gallons of sewage and five times that amount of grey water (all wastewater except from toilets).  About 130 gallons of hazardous waste and 250 gallons of solid waste per ship, plus mechanical wastewater and oils are also produced from a week-long excursion. Scaling up the amount of waste to the total number of passengers for the Caribbean region, this equates to over a billion gallons of sewage and grey water that need to be emptied. Cruise ships also mostly run on diesel and therefore are major air polluters releasing large amounts of carbon dioxide, carbon monoxide and sulphur dioxide into the atmosphere.

The International Convention for the Prevention of Pollution from Ships, also known as MARPOL, was developed by the International Maritime Organization and consists of six main parts to reduce oil pollution, noxious liquids, sewage, garbage, harmful substances and air pollution. While cruise ships represent a small portion of the shipping world, the large capacity for passengers and  services generates a lot more waste relative to their size. The MARPOL regulations prohibit the dumping of sewage near any land, and most ships are permitted to dispose of treated waste within three nautical miles, while untreated waste is permitted 12 nautical miles from land. All dumping of plastics into the ocean is prohibited, while food items are macerated and discharged. Plastics and other waste can be recycled or incinerated and the ash is dumped at sea.


Who regulates the cruise ships?
Unfortunately, while there are improvements in the sewage treatment and some transparency in the process, cruise ships still have a long history of environmental violations and limited accountability. In Caribbean waters, there still needs to be more accountability on the high seas and within the jurisdiction of island nations. Even though many countries globally have signed on to the MARPOL convention, few countries - especially in the Caribbean - have implemented the necessary legislation to enforce the MARPOL rules, making it extremely difficult to hold accountability.

Some destinations including Haiti, Cuba, Dominica, Costa Rica, Grenada, USA and Mexico have not signed on to all sections of the MARPOL convention; and none are signed on for the regulation of sewage treatment. While most of the cruise ships have sewage treatment systems there is less certainty on the proper functioning of the systems; and local authorities in destinations have little time for inspections. In addition, where many cruise ships have functional sewage treatment facilities, the treatment of the larger volume of grey water is less standard when it comes to disposal. While grey water does not have to be treated in the same manner as sewage, it does contain pollutants and coliform that is harmful for the marine environment. Although many cruise companies are American and European, most of the ships are registered in other nations, such as Bahamas, Panama and Bermuda, whose safety and environmental codes may not be as regimented.

While there is no doubt that the business of cruise ships continues to improve their standards, the long-term issue with the current MARPOL convention is the lack of detail with regard to the quality of the waste and garbage treatment and rules for monitoring. We still have the notion that the ocean is endless and can handle all the waste we dump into it. We know that this is not the case: the oceans now feature giant garbage patches and we see evidence of the effects of immense carbon dioxide emissions. Large scale dumping from cruise ships cannot be allowed to continue.

Why do all islands welcome cruise ships?
Cruise ships put tremendous pressure on islands to facilitate them.  Islands are constantly fearful of being excluded from itineraries; and there are more and more cases where islands are sacrificing bits and pieces of their paradise to accommodate these massive floating hotels. The Caribbean region has always been the number one destination for visitors from USA and Europe. Why do we feel that we have to make this compromise? They come for the views. They need to respect the culture and our island ecology, which we need to protect from these incursions of waste. Island nations need to establish and uphold the strictest environmental rules for those that visit us. We must encourage visitors to understand that island vistas are tied to cultures that should be appreciated. There should also be collaboration among island nations, rather than competition to highlight that we are not the same; that we have unique features.  We should encourage the formation of partnerships against external pressures, and work together to enhance visitor experiences.  

Let us invest in tourism infrastructure that appreciates the uniqueness of our nature and culture rather than competing with other islands. One of the first steps is making inter-island travel more affordable to increase connectivity between islands and to develop additional forms of tourism travel. The ocean around is intrinsic to our island-ness; it’s time we took charge of what makes us islands.
