"An important biological species is facing the risk of extinction given the rapid and progressive elimination of its natural conditions for life: humanity"
-Fidel Castro Ruz (Earth Summit, Río de Janeiro, June 12, 1992)
What is to be done about high temperatures, rising sea levels, and increasingly powerful hurricanes? What can we do to be less vulnerable to climate change? Preliminary observations by groups of specialists in the country indicate that sea level has increased on the island an average of 6.77 centimeters since 1966, a process that has accelerated during the last five years. Since the middle of the last century, the average annual temperature has risen 0.9 degrees Celsius, and the coastline is today more fragile than ever. This reality calls for action, and Cuba is acting on the premise of preparing, to avoid lamenting later.
Tarea Vida (Life Task) is the country's most ambitious project addressing climate change. The plan was approved April 25, 2017, by the Council of Ministers and refers to the ideas Fidel expressed at the Earth Summit held in Río de Janeiro, June12, 1992, where he emphasized the seriousness of threats to the human species.
The project led by the Ministry of Science, Technology, and Environment (Citma) is the most all-encompassing, comprehensive among those that have been drafted. With a broad scope and superior organization, it includes and updates the local dimension, citing locations and actions to be taken in the short term (by 2020), long term (by 2050), and long range (2100). Outlined are five strategic actions and 11 tasks meant to counteract the impact being felt in vulnerable areas.
Odalys Goycochea Cardoso, Citma environmental director, told the press that the plan is comprehensive, and includes the identification of prioritized areas and sites, effects, and steps to be taken. She added that the program is being constantly enriched and expanded as its implementation progresses.
ACTION RESEARCH
"Projections for the future indicate that the average increase in sea level could reach 27 centimeters by 2050, and 85 by 2100, values that fall within the estimated ranges for the entire planet. This implies a slow reduction in our dry land surface and a gradual increase in salinization, meaning that our underground aquifers will be impacted at a level that must be taken into consideration," explained Rudy Montero, lead expert within the Environmental Agency's risk assessment group.
Given this panorama, 103 studies have been conducted on dangers, vulnerability, and risks related to weather and precipitation, including the impact of high winds, coastal flooding, and heavy rain. Likewise, research on drought, wildfires, risks of a geological, technological, or health nature have been considered, in order to take action in terms of prevention, preparation, response, and recovery - to confront and reduce risks and vulnerabilities "to adapt to this phenomenon that affects all," Montero said.
Coastal flooding produced by extreme weather phenomena is one of the main dangers resulting from climate change that has been identified. These floods impact human constructions and the natural environment, and along with rising sea levels, put a number of settlements at risk. "We have identified them, and are going to work on new land use plans for each one," he reported.
Among the strategic measures being implemented is the prohibition of any new construction of dwelling in threatened coastal settlements, the most vulnerable and those that are expected to eventually become permanently inundated. Also projected is reducing population density in low-lying areas and ensuring that all new construction is well-adapted to the environment.
Agriculture and livestock ranching also figure among priorities to be addressed, given their importance to the country's food security. Several actions projected address changes in land use patterns as a consequence of rising sea levels and drought: these include reducing cultivated areas along the coastline and in areas affected by saltwater instrusion; diversifying crops; improving soils; as well as introducing and developing varieties resistant to higher temperatures. Also projected is a process of reordering urban planning in identified settlements, and consideration of threatened infrastructure, in accordance with the country's economic situation.
ACCOMPLISHMENTS THUS FAR
Although Citma is the main body responsible for Tarea Vida, it is a project that necessarily involves many ministries and state entities. In carrying out this joint work, Guantánamo is among the provinces that has made the most progress. Reforestation of coastal ecosystems, the construction of water treatment plants, and the promotion of environmentally friendly agricultural practices are just a few examples of what has been accomplished.
The Ministry of Agriculture (Minag), for its part, is working on replanting mangroves to reduce coastal erosion in this eastern province. Efforts are underway in several vulnerable areas, including the communities of Boca, Mata, and Barrancadero.
While their specialists are promoting agro-ecological practices to improve soils and conducting other community participation efforts.
"Thanks to this interest, the Yacabo Arriba mountain ecosystem has recovered some 20 hectares affected by erosion and the impact of Hurricane Matthew," Clark Feoktistova, Citma representative in the province, told the press this past January 25.
The program of conservation measures to ensure sustainable land use, and protect soils, has been implemented in all of Guantánamo's municipalities, he indicated, on state farms, and within cooperatives of both types, credit and services and agricultural production.
In an effort to mitigate the impact of drought in the province, the National Institute of Water Resources has undertaken, among other projects, the construction of several water treatment plants in the municipalities of Niceto Pérez, Manuel Tames and Maisí, along with the drilling of 12 wells to access water in underground aquifers to supply the population.
For its part, the province of Ciego de Ávila has prioritized the use of technology to promote water conservation. Looking to reduce leaks in its distribution network and protect groundwater, key to economic and social life, more than 6,000 meters have been installed in homes, principally in the provincial capital, Morón, and Majagua, according to Héctor Rosabales Pérez, water infrastructure director in the province.
Another short term mitigation effort is the replenishment of sand on beaches on the province's northern keys, that have experienced erosion. This is a problem affecting many areas in the country, including Las Tunas where the impact has been strong.
In addition to the deterioration of sandy beaches along the northern coast, agriculture in this province has been affected by drought and high levels of salt water instrusion in fields close to the coastline, in the municipality of Puerto Padre. Given these difficulties, the Las Tunas Administrative Council created a multi-disciplinary team to manage the Tarea Vida work.
"There are a number of entities that are decisive to the project, such as Physical Planning, that is the guiding body in terms of land use; the University, given its contribution of knowledge via research: the Ministry of Agriculture as responsible for soil resources, among other institutions that must combine forces to achieve the objective," stated Amado Luis Palma, environmental management specialist for the Citma office in Las Tunas.
The province of Sancti Spíritus has also made progress with the implementation of Tarea Vida. The Sur de Jíbaro Agro-industrial Grain Enterprise and the Rice Research Station have done outstanding work in the development of varieties resistant to salinity and drought stress. Of equal importance has been the repair and recovery of irrigation canals to protect the fresh water they carry to the coastline, to help reduce the salt wedge.
Climate change is impacting this province mainly in the form of rising sea levels, which is affecting beaches, tourist development, and agricultural production.
Leonel Díaz, Citma representative in Sancti Spíritus, explained that saltwater instrusion, soil erosion, and the disappearance of mangroves have severely affected the municipalities of Sierpe and Sancti Spíritus.
Over the years, he added, a number of steps have been taken to mitigate the environmental impact of climate change, including important educational work in communities to raise awareness.
SAVING LIVES
Cuba's high level of vulnerability as an island nation, makes rising sea levels precisely the element that most affects the country, in terms of climate change.
In a recent interview in Juventud Rebelde, Elba Rosa Pérez Montoya, minister of Science, Technology and the Environment, stated " Tarea Vida involves everyone."
Thus during her travels around the country, she has prioritized exchanges with provincial authorities, local Party leaders, representatives of Central State Administration bodies, Civil Defense, Physical Planning, and provincial risk assessment centers. She also considers raising consciousness of the issue within the population as essential, to have the support of all in confronting the phenomenon.
"The tasks are highly complicated, since environmental investments must be made, which are characterized by their significant cost and special requirements. Those that have been made are based on the research of many scientists, and are today systematized," the Minister added.
Among Tarea Vida's 11 approved tasks are the identification and implementation of projects to adapt to climate change; assure the availability and efficient use of water to confront drought; reforestation to protect soils and water; stop the deterioration of coral reefs by restoring and protecting them; as well as measures, plans, and projects linked to renewable energy, food security, health, and tourism.
Also included is the protection of urban waterfronts; relocating at-risk human settlements; integrated recovery of beaches, mangroves, and other protective natural ecosystems; waterworks and coastal engineering projects, among others.
Priorities are based on protecting human life in the most vulnerable areas, food security, and the development of tourism.
While Tarea Vida is being enriched as it is being implemented over time, and action is taken, Cuba is aware that what is most important is foreseeing and confronting climate change. The ambitious, complex project shows the government's determination to reduce vulnerability and raise risk perception
