Cuba embarks on a 100-year plan to protect itself from climate change
By Richard Stone - Jan. 10, 2018
------------------------------------------------------------------------
On its deadly run through the Caribbean last September, Hurricane Irma
lashed northern Cuba, inundating coastal settlements and scouring away
vegetation. The powerful storm dealt Havana only a glancing blow; even
so, 10-meter waves pummeled El Malecón, the city’s seaside promenade,
and ravaged stately but decrepit buildings in the capital’s historic
district. “There was great destruction,” says Dalia Salabarría
Fernández, a marine biologist here at the National Center for Protected
Areas (CNAP).
As the flood waters receded, she says, “Cuba learned a very important
lesson.” With thousands of kilometers of low-lying coast and a location
right in the path of Caribbean hurricanes, which many believe are
intensifying because of climate change, the island nation must act fast
to gird against future disasters.
Irma lent new urgency to a plan, called Tarea Vida, or Project Life,
adopted last spring by Cuba’s Council of Ministers. A decade in the
making, the program bans construction of new homes in threatened coastal
areas, mandates relocating people from communities doomed by rising sea
levels, calls for an overhaul of the country’s agricultural system to
shift crop production away from saltwater-contaminated areas, and spells
out the need to shore up coastal defenses, including by restoring
degraded habitat. “The overarching idea,” says Salabarría Fernández, “is
to increase the resilience of vulnerable communities.”
But the cash-strapped government had made little headway. Now, “Irma
[has] indicated to everybody that we need to implement Tarea Vida in a
much more rapid way,” says Orlando Rey Santos, head of the environment
division at Cuba’s Ministry of Science, Technology, and Environment
(CITMA) here, which is spearheading the project. The government aims to
spend at least $40 million on Project Life this year, and it has
approached overseas donors for help. Italy was the first to respond,
pledging $3.4 million to the initiative in November 2017. A team of
Cuban experts has just finished drafting a $100 million proposal that
the government plans to submit early this year to the Global Climate
Fund, an international financing mechanism set up under the United
Nations Framework Convention on Climate Change.
Many countries with vulnerable coastlines are contemplating similar
measures, and another island nation—the Seychelles— has offered to
collaborate on boosting coastal protection in Cuba. But Project Life
stands out for taking a long view: It intends to prepare Cuba for
climatological impacts over the next century. “It’s impressive,” says
marine scientist David Guggenheim, president of Ocean Doctor, a
nonprofit in Washington, D.C., that has projects in Cuba. “Cuba is an
unusual country in that they actually respect their scientists, and
their climate change policy is science driven.”
Rising sea levels pose the most daunting challenge for Cuba. Over the
past half-century, CITMA says, average sea levels have risen some 7
centimeters, wiping out low-lying beaches and threatening marsh
vegetation, especially along Cuba’s southern midsection. The coastal
erosion is “already much worse than anyone expected,” Salabarría
Fernández says. Storms drive the rising seas farther inland,
contaminating coastal aquifers and croplands.
Still worse is in store, even in conservative scenarios of sea-level
rise, which forecast an 85-centimeter increase by 2100. According to the
latest CITMA forecast, seawater incursion will contaminate nearly 24,000
square kilometers of land this century. About 20% of that land could
become submerged. “That means several percent of Cuban land will be
underwater,” says Armando Rodríguez Batista, director of science,
technology, and innovation at CITMA.
To shore up the coastlines, Project Life aims to restore mangroves,
which constitute about a quarter of Cuba’s forest cover. “They are the
first line of defense for coastal communities. But so many mangroves are
dying now,” Salabarría Fernández says. Leaf loss from hurricane-force
winds, erosion, spikes in salinity, and nutrient imbalances could all be
driving the die-off, she says.
Coral reefs can also buffer storms. A Cuban-U.S. expedition that
circumnavigated the island last spring found that many reefs are in
excellent health, says Juliett González Méndez, a marine ecologist with
CNAP. But at a handful of hot spots, reefs exposed to industrial
effluents are ailing, she says. One Project Life target is to squelch
runoff and restore those reefs.
Another pressing need is coastal engineering. Topping Cuba’s wish list
are jetties or other wave-disrupting structures for protecting not only
the iconic Malecón, but also beaches and scores of tiny keys frequented
by tourists whose spending is a lifeline for many Cubans. Cuba has
appealed to the Netherlands to lend its expertise in coastal engineering.
Perhaps the thorniest element of Project Life is a plan to relocate
low-lying villages. As the sea invades, “some communities will
disappear,” Salabarría Fernández says. The first relocations under the
initiative took place in October 2017, when some 40 families in
Palmarito, a fishing village in central Cuba, were moved inland.
Other communities may not need to pull up stakes for decades. But Cuban
social scientists are already fanning out to those ill-fated villages to
educate people on climate change and win them over on the eventual need
to move. That’s an easier sell in the wake of a major hurricane,
Rodríguez Batista says. “Irma has helped us with public awareness,” he
says. “People understand that climate change is happening now.”
