Cuba is implementing an ongoing series of scientific engineering interventions to protect the ecosystems on some 430 beaches at risk from rising temperatures on the planet.
Their protection is a gradual process that involves the periodic monitoring of climate change related factors, to ensure that the models used to forecast rising sea levels are kept up to date.
Doctor in Sciences and chief of the Coastal Processes Department at Oceanology Institute, José Luis Juanes, confirmed that the application of these measures facilitated the adoption of coherent strategies in line with what the Cuban coast requires.
The expert said that one of the themes in the framework of the Dangerous and Vulnerable Coastal Risks, 2050 to 2100 research relates to the study of the results from the beaches in this regard.
More than 70% of the worlds ecosystems are affected by the phenomenon, the main causes of which arise from rising sea levels, increasingly intense storms and the effects of thoughtless human conduct on coastlines.
Juanes explained that these processes result in a continuous and permanent loss of sand, manifest in indexes such as vegetation blooms on rocky surfaces and receding coastlines.
He stated that Cuba is not exempt from the symptoms of such consequences that similarly affect other Caribbean nations, provoking significant ecological and economic losses.
According to the expert, in order to mitigate against the impact of such natural processes, a series of strategies are applied in Cuba that are the result of 40 years of research.
He continued, “the studies undertaken during the 1970’s permitted the understanding that erosion was a widespread phenomenon, even on beaches free from human activity...
“They also demonstrated that this natural process is in full development and is one more effect of rising sea levels”.
Severe storms, that also cause serious harm to sand producing ecosystems such as marine pastures and coral reefs, are presently the main agents of erosion in Cuba.
He emphasized that “In 2012 for example, Hurricane Sandy destroyed the beaches in the south eastern zones of Santiago de Cuba, Holguin, Granma and Guantanamo, and during its crossing to the north it inflicted a lot of damage on the Holguin and Las Tunas coasts”.
Juanes said that on Cuba’s north western coastline, particularly on the beaches of Varadero, the Camaguey Plains Archipelago, and the zone to the east of Havana the storms associated with cold fronts have an aggressive impact. He added that the extra tropical lows in the years 1986, 91 and 92 were critical moments for this region.Share on FB Share on TT
