The worldwide scuba diving business generates between $8.5 billion and $20.4 billion every year, whereas additionally offering widespread marine conservation advantages, a brand new examine has discovered.
The diving sector helps as much as 124,000 jobs throughout 170 nations on an annual foundation, contributing to each ocean ecology and native communities, in line with the examine, printed Friday in Cell Reports Sustainability.
“Scuba diving is fairly distinctive as a result of it makes you spend time underwater,” co-author Fabio Favoretto, a postdoctoral researcher on the College of California San Diego’s Scripps Establishment of Oceanography, stated in a press release.
“You possibly can sail or surf above a lifeless ocean, however scuba divers discover if there aren’t any fish,” added Favoretto, who additionally runs the Atlas Aquatica Undertaking, a part of a U.N.-based marine biology initiative.
The very act of diving, he defined, depends on the well being of the ocean — thereby fostering a internet “optimistic for conservation as a result of it makes divers allies.”
Earlier studies have urged that improved conservation might increase dive revenue, by attracting people who find themselves keen to pay greater costs for the expertise, the authors famous. A few of that very same analysis, they famous, has additionally proven that about 70 p.c of all dives happen in marine protected areas — a testomony to diver choice.
Whereas ocean-based tourism is a widely known contributor to the economic system, the authors stated that the precise function of scuba diving at international scale has lengthy been a thriller.
Co-author Octavio Aburto-Oropeza, a marine biologist at Scripps, previously focused solely on Mexico, discovering in 2021 that the dive business there produced $725 million yearly for the nation’s economic system — nearly as a lot as all the fishing sector.
Within the new examine, the researchers expanded their attain to all the world, compiling an inventory of greater than 11,500 dive operators in 170 nations and utilizing knowledge from Google Maps and the Skilled Affiliation of Diving Instructors. After validating their knowledge with native sources, they performed a web-based survey of 425 companies throughout 81 nations.
The authors then used the survey responses to calculate cash spent on diving actions, in addition to oblique funds spent on lodges, meals and transportation by the world’s estimated 9 million to 14 million annual leisure divers. They then used statistical modeling to extrapolate the figures to gauge approximate international impression.
Finally, the evaluation concluded that complete spending quantities to between $8.5 billion and $20.4 billion, with between $900 million and $3.2 billion going on to diving.
Relating to workforce, the researchers noticed that 80 p.c of staff are native or nationwide residents.
In the meantime, dive operators extensively cited deep issues about ecosystem degradation from different industries over the previous decade, in line with the examine. Adjustments reported have been associated to biodiversity, species abundance, coral bleaching, air pollution and water high quality.
“We present that diving generates numerous earnings, and it does this with out degrading the surroundings like extractive industries similar to fishing or mining,” Aburto-Oropeza stated.
“We hope that exhibiting the dimensions of the financial impression from this exercise will encourage insurance policies that put money into diving by growing marine protections,” he added.
Aburto-Oropeza and his colleagues positioned dive tourism as a mannequin for a “Blue Economy” — an internationally acknowledged idea that reveals how coastal communities can thrive whereas additionally defending their assets.
“Not like mass tourism operations that may hurt native communities and marine environments, dive tourism, when managed effectively, will be economically viable, socially equitable and environmentally sustainable,” lead writer Anna Schuhbauer, a fisheries scientist on the College of British Columbia, stated in a press release.
“With a vested curiosity in wholesome ecosystems and considerable marine life, dive operators are pure allies in conservation efforts,” Schuhbauer added.
