“They don’t sell you enough fuel at the gas stations and the line barely creeps forward because there are also many irregularities and corruption. It’s exhausting,” said engineer Rolando Estupiñán, who was driving an old Soviet Union-made Lada. When he spoke to IPS in Havana, he was still a long way from the pumps at the station and had given up hope of working that day.

Lisbet Brito, an accountant living in the Cuban capital, lamented in a conversation with IPS that “the public buses take a long time. Private cars (that act as taxis) are making shorter trips and charging more. Nobody can afford this. It’s very difficult to get to work or school, or to a medical or any other kind of appointment.”

Brito said another fear “is that food prices will rise further or supplies will decrease, if the shortage of oil makes it difficult to supply the markets.”

External and internal factors, including the fuel shortage, contribute to low levels of agricultural production, which is insufficient to meet the demand of the 11.1 million inhabitants of this Caribbean island nation.

The outlook is made even more complex by the macroeconomic imbalances, marked by partial dollarization, high inflation and depreciation of wages, salaries and pensions which have strangled household budgets.

Asiel Ramos, who uses his vehicle as a private taxi in this city of 2.2 million people, justified the increase in his rates “because the cost of a liter of diesel skyrocketed” on the black market, where it ranges from a little more than a dollar to three dollars, in sharp contrast to the average monthly salary of around 35 dollars.

“I pay taxes and I have to keep the car running so my children and wife can eat. I can’t spend days stocking up on fuel, and when it’s over, go back again. If I buy ‘on the left‘ (a euphemism for buying on the black market) I have to raise my prices,” Ramos told IPS.

To get around, most Cubans depend on the public transport system, based mainly on buses, which are less expensive than private taxis. But the chronic deficit of equipment, spare parts, lubricants and other inputs, added to the fuel shortage, means service is irregular, the most visible expression of which is the packed bus stops.

Measures

The fuel shortage drove the authorities to announce on the night of Apr. 25 the cancellation of the traditional parades for May 1, International Workers’ Day, and other activities such as political rallies or workplace, community or municipal events, as a rationing and austerity measure, and to declare that only essential transportation would be available.

In the capital, instead of the workers’ march through the José Marti Plaza de la Revolución, a rally was called for May 1 along the Havana Malecón or seaside boulevard, which expects some 120,000 people coming on foot from five of the 15 Havana municipalities.

On Apr. 17, the Minister of Energy and Mines Vicente de la O Levy said on television that the fundamental cause of the shortage of diesel and gasoline is related to breaches of contracts by suppliers.

He said the U.S. embargo “makes it very difficult to obtain ships to transport the fuel, to seek financing and to meet the normal requirements of these contracts.”

In November, during President Miguel Díaz-Canel’s tour of Algeria, Russia, Turkey and China, agreements were signed with some of these countries for the stable supply of hydrocarbons, power generation and the modernization of thermoelectric plants.

Venezuela and Russia appear to be the country’s main energy suppliers.

On Apr. 23, the general director of the state company Unión Cuba Petróleo (Cupet), Néstor Pérez, told national media outlets that “one of the closest suppliers despite having innumerable production limitations… has guaranteed the supply of some products (refinable crude and derivatives) that somewhat alleviate the existing situation, but do not cover all the demands of the economy and the population.”

Presumably Pérez was referring to Venezuela, although he did not specifically say so, because that country has been the largest supplier of hydrocarbons this century, although due to its own internal crisis its exports to Cuba have clearly declined.

De la O Levy noted that, based on negotiations with international suppliers, an improvement is expected in May, although the availability of fuel will not reach the levels seen in 2017 or 2018, when the country was in a more favorable situation.

The priorities in the use of the reserves are the health and funeral services, public transportation and transport of merchandise, as well as the potato harvest, the official said.

The government of Havana, which as a province encompasses the 15 municipalities that make up the capital, limited the sale of diesel to 100 liters per vehicle and 40 liters of gasoline. In the remaining 14 provinces, rationing measures were also ordered.

Several universities postponed the entry of scholarship students until the first week of May, and announced online classes and consultations.

Sales of liquefied petroleum gas (LPG) are also affected, used by more than 1.7 million consumers, although the next arrival of a ship with the product should bring back stability to the service, according to officials.

Electricity generation deficit

This situation coincides with breaks and repairs in some of the 20 thermoelectric generation plants, which have operated for an average of more than 30 years.

These plants process, for the most part, heavy national crude oil, with a sulfur content between seven and 18 degrees API, which requires more frequent repair cycles that are sometimes postponed due to a lack of financing.

Around 95 percent of the electricity generated in Cuba comes from fossil sources.

This country consumes some 8.3 million tons of fuel per year, of which almost 40 percent is nationally produced.

President Díaz-Canel explained on Apr. 14 that due to the number of thermoelectric blocks under repair “we have had to depend more on distributed generation that basically consumes diesel” in the country’s 168 municipalities.

The generation deficits cause blackouts, although of a lesser magnitude than the 10 to 12-hour a day cuts that for a large part of 2022 affected different parts of the country and sparked demonstrations and pot-banging protests in poor neighborhoods of several municipalities.

The rest of the electricity generation comes from gas accompanying national oil, and floating units rented to Turkey, while renewable energy sources account for only five percent of the total.

The current energy situation is occurring as summer looms, when temperatures above 35 degrees Celsius increase the use of fans and air conditioners, while a majority of the 3.9 million homes in Cuba depend on electricity for cooking food.

Promoting renewable sources

“We must further promote renewable sources and stimulate a change from fuel-guzzling, polluting vehicles that are more than half a century old to more modern and efficient ones,” computer scientist Alexis Rodríguez told IPS from the eastern city of Holguin, where he lives.

The transformation of the national energy mix is ??considered by the government a matter of national security, and as part of its plans it aims for 37 percent of electricity to come from clean energy by 2030.

Since 2014, Cuba has had a policy for the prospective development of renewable energy sources and their efficient use, and in 2019 Decree Law 345 established regulations to increase the proportion of renewables in electricity generation and gradually decrease the share of fossil fuels.

Such a significant transformation will require investments of some six billion dollars, authorities in the sector estimate, which constitutes a challenge for a country whose main sources of revenue are dwindling, and which has pending a restart of interest payments on its debt to international creditors.

“It is also important to encourage the use of bicycles and electric vehicles, but they must be sold at reasonable prices, on credit as well, with guarantees of spare parts and the improvement of infrastructure,” Rodríguez added.

In addition to hybrid buses, a hundred light electric vehicles have been added to the capital’s public transport system that contribute to citizen micromobility and to reducing carbon emissions.

In recent years, the customs agency made provisions more flexible for citizens and companies to import solar panels. Although official data are not available, the measure has not had a significant influence.

Measures for the import and assembly on the island of bicycles, motorcycles and three and four-wheel electric vehicles – more than half a million of which circulate in Cuba – also bolster the mobility of people and families.

However, the high prices and sales only in hard currencies curb the expansion and use of more environmentally-friendly vehicles. Another hurdle is the dependence on the national power grid to recharge the batteries and the absence of service stations for electric vehicles.

Cuban Innovator Drives Sustainable Energy Solutions

  • by Luis Brizuela (havana)
  • Inter Press Service

With two tanks, glass, aluminum sheets, as well as cinderblocks, sand and cement, the 86-year-old retiree created, in 2006, a solar heater that meets his household needs.

“You build it today and tomorrow you have hot water; anyone can do it, and if they have a bit of advice, all the better,” said the retired mid-level machine and tool repair technician who lives in the municipality of Regla, one of the 15 that make up Havana.

He also designed and made a dryer that uses the heat of the sun to dehydrate fruits, spices and tubers, which he assembled mostly with recycled products such as pieces of wood, nylon, acrylic and aluminum sheets.

On the roof of his house, 16 solar panels imported in 2019 provide five kilowatts of power (kWp) and help run his small automotive repair shop where he works on vehicles for state-owned companies and private individuals, an independent enterprise that he set up next to his house.

In addition to covering his household needs, he provides the surplus electricity to the national grid, the National Electric Power System (SEN).

Morffi said more training is needed among personnel involved in several processes, and he cited delays of more than a year between the signing of the contract with Unión Eléctrica and the beginning of payments for the energy surpluses provided to the SEN, as well as “inconsistency with respect to the assembly” of the equipment.

Although Cuba has a national policy on renewable energy sources, “there is still a lot of ignorance and very little desire to do things, and do them well. Awareness-raising is needed,” he argued.

The innovator believes that despite the economic conditions, with a little ingenuity people can take advantage of the natural elements, because “the sun shines for everyone; the wind is there and costs you nothing, but your wealth is in your brain.”

In his backyard, a small solar panel keeps the water flowing from a well for his barnyard fowl and an artificial pond holding a variety of ornamental fish as well as tilapia for family consumption.

The construction of a small biodigester, about four cubic meters in size, is also at an advanced stage on his land, aimed at using methane gas from the decomposition of animal manure and crop waste, for cooking.

Morffi, who manages these activities with the backing of several family members, also plans to import three small wind turbines of 0.5 kWp each and a new batch of 4 kWp solar PV panels.

His vision is to turn his house into a space for the production and promotion of renewable energies in Cuba.

To this end, he has the support of the non-governmental Cuban Society for the Promotion of Renewable Energy Sources and Respect for the Environment (Cubasolar), of which Morffi has been a member since 2004.

Since 2014, Cuba has had a Policy for the Development of Renewable Energy Sources and their Efficient Use. And in 2019, Decree Law 345 established regulations to increase the share of renewables in electricity generation and steadily decrease the proportion represented by fossil fuels.

According to studies, this archipelago of more than 110,800 square kilometers with an annual average of 330 sunny days receives an average solar radiation of more than five kilowatts per square meter per day, considered to be a high level that provides enormous potential in terms of energy.

The solar energy program appears to be the most advanced and with the best opportunities for growth. Over the last decade, several solar parks have been built, providing more than 75 percent of the renewable energy produced locally.

But clean sources account for just five percent of the island’s electricity generation, an outlook that the authorities want to radically transform, setting an ambitious goal of 37 percent by 2030.

Biogas Spreads Among Cuban Families as an Alternative Energy

  • by Luis Brizuela (candelaria, cuba)
  • Inter Press Service

The biodigester in the back of her house in the rural community of Carambola, Candelaria municipality in the province of Artemisa, 80 kilometers west of Havana, brings Rojas the benefits of not using firewood and electricity for cooking, with the consequent reduction in electric bills and cooking time.

It was built in 2011 with the help of her husband Edegni Puche, who worked in the installation of the gas pipes and other aspects.

Rojas and Puche, who raise pigs and grow fruits and vegetables on their small family farm, were advised by specialists from the Cuban Society for the Promotion of Renewable Energy Sources and Respect for the Environment (Cubasolar) and the Movement of Biogas Users (MUB).

Rojas also received materials from the municipal government and the local pig company to build the small-scale Chinese-type fixed-dome biodigester of about six cubic meters in size.

She estimates that the total cost of the project ranged between 500 and 600 dollars at the exchange rate at the time.

Construction costs depend on the size, type and thickness of the material, as well as the characteristics of the site.

However, experts estimate that the average minimum cost for the construction of a small-scale biodigester – which more than covers the cooking needs of a household – currently stands at around 1,000 dollars in a country with an average monthly salary equivalent to 160 dollars at the official exchange rate.

Rojas says that “before, when we cleaned the pens, the manure, urine and waste from the pigs’ food piled up in the open air, in a corner of the yard. It stank and there were a lot of flies.”

The organic matter is now decomposed anaerobically by bacteria, but in a closed, non-polluting environment that provides methane gas as an energy resource, instead of releasing it into the atmosphere.

Thanks to the alternative energy source Rojas can also keep her nails painted and her hair clean for longer.

It also helped her husband and two young children become more involved in household chores, cleaning the yard and taking care of the animals on the family farm, “and created greater awareness of environmental care.”

In addition, biogas technology provides biol and biosol – liquid effluent and sludge, respectively – which are ideal for fertilizing and restoring soils, “as well as watering and keeping plants green,” says Rojas, who has a lush garden where she grows varieties of exotic orchids.

Her biodigester has also proven useful to the community, because when there are blackouts due to tropical cyclones that frequently affect the island, “neighbors have come to heat up water and cook their food,” she adds.

There are an estimated 5,000 biodigesters in Cuba, with the potential to expand the network to 20,000 units, at least the small-scale ones, according to conservative estimates by experts.

More than 90 percent of Cuba’s electricity comes from burning fossil fuels in aging thermoelectric plants and diesel and fuel oil engines, in a nation where a significant percentage of the 3.9 million homes use electric power as the main energy source for cooking and heating water for bathing.

Local Solutions Boost Sustainable Micro-Mobility in Cuba — Global Issues

Residents of the Fontanar neighborhood in the Cuban capital are pleased with the incorporation of electric three-wheel vehicles to shorten distances between sectors within Boyeros, one of the municipalities that make up Havana. CREDIT: Jorge Luis Baños/IPS
  • by Luis Brizuela (havana)
  • Inter Press Service

“Connecting nearby places with electric means of transportation has been very timely and a relief,” said Dania Martínez, referring to the well-known Ecotaxis, six-seater vehicles that since June have been providing transportation between neighborhoods within the municipality of Boyeros, one of the 15 that make up Havana.

The teacher and her son were waiting for one of these vehicles at the Fontanar shopping center to take them to Wajay, their neighborhood on the outskirts of Havana, when IPS asked them what they thought about the service.

“Public transportation is not good in this area, far from the city center, and private taxis charge you a high fee. Just getting somewhere else five kilometers away can be difficult. Hopefully the three-wheelers will spread to other places,” Martinez said.

She was referring to light motorized vehicles that resemble some kinds of Asian autorickshaws, which are also known locally as motocarro or mototaxi, with a capacity for six people in the back.

With a range of 120 kilometers, these three-wheeled electric vehicles cover three two- to four-kilometer routes for a price of four pesos, or 17 cents at the official exchange rate in a country with an average monthly salary equivalent to about 160 dollars.

The fleet of 25 vehicles is part of the Neomovilidad project, implemented by the General Directorate of Transportation of Havana (DGTH) and the United Nations Development Program (UNDP) office in Cuba.

For its implementation until 2023, it has a budget of 1.9 million dollars donated by the Global Environment Facility (GEF).

“From its start in 2019, Neomovilidad has aimed to strengthen the regulatory framework for an efficient transition to a low-carbon urban transport system in Havana, with a positive environmental impact,” Reynier Campos, director of the project, told IPS.

During the first three months of operation, more than 135,000 people were transported, with an estimated monthly emission reduction potential of 6.12 tons of carbon dioxide equivalent.

On the downside, Ecotaxis can only recharge at night by connecting to the national power grid, 95 percent of which depends on the burning of fossil fuels to generate electricity. Recharging is carried out at the three-wheel vehicles’ parking area and is done at night because it takes about six hours.

However, there are plans to contract power from solar parks of the state-owned electric utility Unión Eléctrica de Cuba, in order to offset consumption, executives said.

Other fleets of Ecotaxis provide service in the municipalities of La Habana Vieja, Centro Habana and Guanabacoa, also with UNDP support, and contribute to the national commitment to climate change mitigation actions.

Campos explained that Neomovilidad is a pilot project in Boyeros that could be extended to other Havana municipalities and cities of this Caribbean island nation of 11.1 million people, where public transportation is one of the most pressing long-term issues.

Long-standing problem

With its 2.2 million residents and tens of thousands of people who live here on a short-term basis, Havana has 1.4 million people using transportation daily, one million of whom use the state-owned bus company Empresa de Ómnibus Urbanos, according to the Ministry of Transportation.

But the most recent official reports acknowledge that less than 50 percent of the fleet of public buses are currently operating in the capital.

The Cuban government blames the U.S. embargo as the main obstacle to the purchase of spare parts, as well as the lack of access to credit to repair and renovate buses, the main form of public transportation.

Problems with the availability of fuel and the number of drivers who find work in sectors with greater economic benefits also undermine an irregular service whose most visible face is the overcrowded stops at peak hours.

Figures indicate that 26 percent of the total estimated passengers in Havana use private taxis, which charge higher rates that not everyone can afford.

There are also non-agricultural transportation cooperatives with cabs and minibuses, as well as buses of the state-owned Transmetro Company, that provide services with set schedules.

About 80 percent of Latin America’s inhabitants live in towns and cities, and urban public transport remains essential in regional mobility plans.

Cuba is quietly taking steps to encourage the use of alternative vehicles and increase electricity production from renewable sources, which plans aim to raise from the current five to 37 percent by 2030.

As a result of flexible customs regulations for their importation, as well as assembly, it is estimated that half a million bicycles, motorcycles and electric three-wheelers are in circulation on the island, helping families get around.

However, high prices and sales only in foreign currency hinder their spread. Some of the most economical ones cost over 1,000 dollars, while others range from 2,000 to 5,000 dollars in government stores.

Gender focus to reduce gaps

Neomovilidad stands out for encouraging the incorporation of women as drivers and promoting female employment.

“In addition to giving me a job, my income is higher, helping me support my nine-year-old son,” Mirelis Cordovés, a single mother who is one of the 13 women who now form part of the project’s team of drivers, told IPS.

Latin American nations such as Chile, Colombia, Costa Rica, the Dominican Republic and Panama have adopted national policies related to the development of electric mobility.

In the case of Cuba, the proposal is “a vision for the development of electromobility from the Ministries of Transport, Energy and Mines and Industry, with guidelines and priority lines in public transport, including the conversion of vehicles,” said Campos.

He said that Neomovilidad proposes to promote public policies that contribute to Sustainable Urban Mobility.

The project urges considering the specific mobility needs of each social group and mainstreaming variables such as gender, age and accessibility, in order to reduce gaps.

The National Gender Equality Survey, conducted in 2016 but whose results were released in February 2019, showed that women primarily bear the burden of care work.

They are the ones who spend the most time taking children, family members or other people under their care to schools, hospitals or to buy food, the survey showed.

Transportation was identified as one of the top three problems for Cuban women, second only to low incomes and housing shortages.

The study drew attention to the correlation between time use and income inequality, because cheaper transportation options (public buses) increase travel delays.

Experts consulted by IPS consider that in the case of Cuba, a developing nation shaken by a three-decade economic crisis and pressing financial problems, there is no need to wait for solutions that demand large resources, if small and accessible alternatives can be devised to organize and facilitate mobility.

Integrating bicycles

As part of Neomovilidad, a pilot system of public bicycles should be inaugurated before the end of 2022, with six stations and 300 bicycles, also in the municipality of Boyeros.

The autonomous venture Inteliforja will operate the bicycle mobility system as a local development project, in conjunction with the DGTH, after winning a bidding process.

“The main activity will be the rental of bicycles at affordable prices. It will include other services such as parking, mechanical workshops, as well as complementary activities such as bicycle touring, package delivery and community activities to encourage the use of this means of transport,” explained Luis Alberto Sarmiento, one of the managers of Inteliforja.

Sarmiento told IPS that the central workshop will be located at the José Antonio Echeverría Technological University of Havana, where there are several engineering and architecture courses.

“We plan to install a solar panel-powered station there to charge students’ motorcycles and electric bicycles,” said the young entrepreneur.

“Farther in the future, when we have more resources, we plan to introduce bicycles or three-wheelers for the transportation of elderly and disabled people,” Sarmiento added.

Although electric mobility and the use of bicycles are seen as promoting more open, safer, cleaner and healthier cities, Cuba faces multiple challenges in this regard, starting with the need to lower the price of vehicles and ensure the stable availability of parts and components.

Other pending issues are the lack of recharging points for refueling outside the home, the lack of bicycle lanes or green lanes, in addition to the urgent need to repair a road network, 75 percent of which is classified as in fair or poor condition.

Cuban Innovator Uses Sunlight to Create a Model Sustainable Space — Global Issues

Félix Morffi, an 84-year-old retiree, shows a self-made solar heater and solar panels installed on the roof of his house in the municipality of Regla in Havana. His hope is that his house will soon become an experimental site for the use of renewable energies and that students will learn about the subject in situ. CREDIT: Jorge Luis Baños/IPS

  • Inter Press Service

With two tanks, glass, aluminum sheets, as well as cinderblocks, sand and cement, the 84-year-old retiree created, in 2006, a solar heater that meets his household needs, which he proudly displays.

“You build it today and tomorrow you have hot water; anyone can do it, and if they have a bit of advice, all the better,” said the retired mid-level machine and tool repair technician.

A magnet magnetically treats the water by means of a system that purifies it and makes it fit for human consumption, without additional energy costs.

Also on the roof of the house, a cluster of 16 photovoltaic panels imported in 2019 provide five kilowatts of power (kWp) and support the work of his small automotive repair shop where he works on vehicles for state-owned companies and private individuals.

This is an independent enterprise carried out by Morffi on part of his land in Regla, one of the 15 municipalities that make up Havana.

In addition to covering his family’s household needs, he provides his surplus electricity to the national grid, the National Electric Power System (SEN).

As part of a contract with the Unión Eléctrica de Cuba under the Ministry of Energy and Mines, for the surplus energy “we receive an average of more than 2,000 pesos a month (about 83 dollars at the official rate), more or less the amount we pay for our consumption during the same period,” Morffi told IPS in an interview at his home.

But he said that the rate of 12.5 cents per kilowatt of energy delivered to the SEN perhaps should be increased if the government wants more people to produce solar energy.

Since 2014, Cuba has had a Policy for the Development of Renewable Energy Sources and their Efficient Use, and in 2019, Decree Law 345 established regulations to increase the share of renewables in electricity generation and steadily decrease the proportion represented by fossil fuels.

Other regulations have been added, such as the one that exempts foreign companies that carry out sustainable electricity generation projects from paying taxes on profits for eight years.

Other decisions seek to encourage self-sufficiency through decentralized generation with the sale of surplus energy to the SEN, as well as tariff exemptions to import photovoltaic systems, their parts and components for non-commercial purposes.

Great solar potential

According to studies, Cuba receives an average solar radiation of more than five kilowatts per square meter per day, considered to be a high level. There is enormous potential in this archipelago of more than 110,800 square kilometers which has an annual average of 330 sunny days.

By the end of 2021, some 500 million dollars were invested in expanding the share in the energy mix of solar, wind, biomass and hydroelectric sources, according to data from the Ministry of Energy and Mines.

The solar energy program appears to be the most advanced and with the best opportunities for growth.

The solar parks operating in the country contribute 238 megawatts, more than 75 percent of the renewable energy produced locally.

In addition, more than 160,000 of the nation’s 3.9 million homes, mostly in remote mountainous areas, receive electricity from solar modules, statistics show.

But clean sources account for barely five percent of the island’s electricity generation, an outlook that the authorities want to radically transform, setting an ambitious goal of 37 percent by 2030.

It is a matter of national security to substantially modify the energy mix in Cuba, which is highly dependent on fossil fuel imports and hit by cyclical energy shortages.

The island is in the grip of an energy crisis with blackouts of up to 12 hours or more in some areas, due to the deterioration of the network of 20 thermoelectric generation blocks with an average operating life of 30 years and in need of frequent repairs.

Added to this is the rise in the international prices of diesel and fuel oil, as well as the shortage of parts to keep the engines and generators powered by these fuels operational in Cuba’s 168 municipalities.

Putting on the brakes

Government authorities point to the U.S. embargo as a factor holding back the growth of renewable energies, blaming it for discouraging potential investors and hindering the purchase of modern components and technologies.

On the other hand, inflation, the partial dollarization of the economy and the acute shortage of basic necessities, including food, leave most families without many options for turning to the autonomous production of clean energy, even if they recognize its positive environmental impact.

One of the authorized state-owned companies markets and assembles 1.0 kWp solar panel systems for the equivalent of about 2,300 dollars in a country where the average monthly salary is estimated at 160 dollars, although it is possible to apply for a bank loan for their installation.

People who spoke to IPS also mentioned the difficulties in storing up solar energy for use at night, during blackouts or on cloudy or rainy days, considering the very high price of batteries.

Morffi said more training is needed among personnel involved in several processes, and he cited delays of more than a year between the signing of the contract with Unión Eléctrica and the beginning of payment for the energy surpluses contributed to the SEN, as well as “inconsistency with respect to the assembly” of the equipment.

Although there is a national policy on renewable energy sources, “there is still a lot of ignorance and very little desire to do things, and do them well. Awareness-raising is needed,” he argued.

Combining renewable energies

Morffi believes that despite the economic conditions, with a little ingenuity people can take advantage of the natural elements, because “the sun shines for everyone; the air is there and costs you nothing, but your wealth is in your brain.”

He shows a dryer that uses the heat of the sun to dehydrate fruits, spices and tubers, which he assembled mostly with recycled products such as pieces of wood, nylon, acrylic and aluminum sheets.

Other equipment will require a significant investment, such as the three small wind turbines of 0.5 kWp each that he plans to import and a new batch of 4.0 kWp photovoltaic solar panels, for which he will have to apply for a bank loan.

At the back of his house, a small solar panel keeps the water flowing from a well for his barnyard fowl and an artificial pond holding a variety of ornamental fish as well as tilapia for the family to eat.

The construction of a small biodigester, about four cubic meters in size, is also at an advanced stage on his land, aimed at using methane gas from the decomposition of animal manure, for cooking.

According to Morffi, who manages these activities with the support of several family members, his home is on its way to becoming an experimental site for the use of renewable energies.

A specialized classroom may be built there, so that students can learn about the subject in situ.

So far in the design phase and in discussions with potential supporters, this local development project could even install “solar heaters in places in the community such as the doctor’s office, a day center and a cafeteria for the elderly,” said Morffi.

He said the idea should receive support from international donors, the government of the municipality of Regla, and Cubasolar, a non-governmental association dedicated to the promotion of renewable sources and respect for the environment, of which Morffi has been a member since 2004.

“We are willing to advise anyone who wants to install solar panels, heaters or dryers, everything related to renewable energies. We have knowledge and experience and have something to contribute,” he said.

In the Face of Scarcity, Cubans Dream of Once Again Drinking Their Daily Cup of Coffee — Global Issues

  • by Luis Brizuela (havana)
  • Inter Press Service

“If I don’t drink it I don’t feel good, I have a headache all day. For me drinking coffee is almost as important as eating,” said Barrios, who receives from family members quantities of coffee beans “brought from the east, where the best coffee in the country is produced,” which she mixes with chickpeas before roasting, to make it stretch farther.

After drinking her own cup, Barrios sells coffee as a street vendor in the early morning in the old town district of Centro Habana, one of the 15 municipalities that make up Havana.

“That sip of hot coffee is sometimes the entire breakfast of people who go to work and don’t have it at home because they leave in a hurry, or because they don’t have any coffee, which in addition to being scarce has become very expensive,” Barrios said in an interview with IPS.

Coffee is part of the basic food basket on the island. The government sells each month, per person and on a subsidized basis, a 115-gram package mixed with 50 percent chickpeas.

In recent months there have been delays in distribution due to the late arrival of raw materials, including packaging paper, given the financial problems faced by this Caribbean island country in the midst of the deepening structural crisis of its economy, which dates back three decades.

When consulted by IPS, residents in some of Cuba’s 168 municipalities admit that the coffee quota “is barely enough for seven to 10 days, if you’re thrifty.”

People often resort to the black market to acquire additional quantities. There, the same 115-gram package, often taken from stores or government establishments, is sold for the equivalent of half a dollar.

Better quality Cuban and foreign coffee brands are sold almost exclusively in stores in convertible currencies, unaffordable for many families who are paid wages in the devalued Cuban peso.

For example, a kilo of the national brand Cubita costs about 15 dollars in a country with an average monthly salary equivalent to 32 dollars, according to the official rate of 120 pesos to the dollar.

Boosting coffee production on the plains

Coffee arrived in Cuba in 1748 and production received a major boost after the Haitian revolution (1791-1804), with the immigration of French-Haitian farmers who settled in mountainous areas of the eastern part of the island where they set up coffee plantations, some of whose ruins were declared World Heritage Sites by UNESCO in the year 2000.

During part of the 19th century, this country was the main exporter of coffee to Europe, exporting 29,500 tons in 1833, for example.

Statistics show that the historical record was reached in the 1961-1962 harvest: 60,300 tons. But after that production declined and currently volumes do not exceed 10,000 tons per year.

With a demand of 24,000 tons per year, this once important exporter actually has to import coffee from other countries, but in quantities that do not meet its needs.

According to Elexis Legrá, director of coffee and cocoa of the Agroforestry Group (GAF), attached to the Ministry of Agriculture, Cuba exports the Arabica variety, the highest quality, produced by coffee growers in mountainous areas.

The prospect is to start exporting small quantities of the Robusta variety, in greatest demand on the international market.

This year, the goal is to export some 2,700 tons, a figure similar to that of 2020, according to industry executives.

Experts say the main factors behind the drop in production are pests, tropical cyclones that frequently hit the island, the effects of climate change, the depopulation of rural and mountainous areas and obsolescent technology.

About 90 percent of national coffee production comes from the mountains in the four easternmost provinces: Holguín, Granma, Santiago de Cuba and Guantánamo, where the highest quality varieties are grown, due to tradition and favorable microclimates.

However, since 2014 the Cuban government began identifying soils with adequate conditions for planting coffee in lowland regions, and training courses and technical advice have been provided to new coffee growers.

“They used to say you couldn’t grow coffee here, and today we have some 2,000 bushes on just half a hectare,” Juan Miguel Fleitas told IPS. In addition to growing root vegetables, fresh produce and fruit and raising livestock, he also grows coffee on his family farm, Victoria 1, in the capital’s Guanabacoa municipality.

The 29-hectare farm, with six workers, belongs to the 26 de Julio Basic Units of Cooperative Production (UBPCs).

The UBPCs manage both private properties and state lands granted in usufruct in this socialist nation with a largely centralized economy.

“In the cooperative we have about eight hectares of coffee, dispersed. We are working on the introduction of Vietnamese coffee. It has a good yield, with a larger bean,” the farm’s head of agricultural production, Jorge Luis Gutiérrez, told IPS.

The beans came from seed banks from the east of the island, as part of the Cuba-Vietnam collaboration project, developed from 2015 to 2020.

In the 1970s, Cuban experts taught Vietnamese farmers and extension workers to plant this variety, in a nation then devastated by the war with the United States (1955-1975).

Vietnam is today the second largest exporter of the bean and shares its know-how with Cuba to achieve Robusta coffee cuttings that guarantee renewed plants with superior characteristics, in order to increase quality and yields.

Cuba’s “program to grow coffee in the lowlands” has set a goal of planting 7,163 hectares of coffee in production areas in several of the country’s 15 provinces.

So far, 1,200 hectares have been planted, another 700 hectares are in preparation, and the aim is to harvest more than 4,000 tons by 2030, according to official estimates.

By that date, Cuba’s “coffee production development program” aims to harvest 30,000 tons of coffee nationwide.

Organic coffee

Esperanza González is committed to growing coffee “without chemicals or herbicides, only using agroecological management techniques, earthworm humus, lots of organic matter and free-roaming chickens that help fertilize the soil with their excrement.”

González, who returned to Cuba after living for years in the Canadian province of Manitoba, was granted in 2017 in usufruct the eight-hectare Farm 878 that she renamed Doña Esperanza, located in the town of Santa Amelia, in the municipality of Cotorro, near the capital.

Since 2008, the Cuban government has granted unproductive and/or degraded land in usufruct to recuperate it and bolster food production.

This policy forms part of plans to strengthen food security in a country that is up to 70 percent dependent on food imports, whose rising prices lead to a domestic market with unsatisfied needs and shortages.

González, who through her own efforts imported “the equipment and the technology to be able to completely process our coffee,” told IPS that she hopes that with this year’s harvest they will “have a local quality product packaged under our own brand.”

However, she also highlighted “the exchange with coffee growers in the municipality of Segundo Frente (in the province of Santiago de Cuba), from whom we have received baskets to harvest coffee and give the final preparations to our crop.”

In 2021 “we harvested half a ton of good quality beans. We hope that little by little Doña Esperanza will become a lowlands coffee farm with higher volumes of export-quality and national-consumption production, which is so much needed,” she said.

Several initiatives with international support seek to strengthen the value chains associated with coffee production, restore the soils and ecosystems where coffee is grown, and identify markets for selling coffee grown with sustainable practices.

Prodecafé, an agroforestry cooperative development initiative that will run until 2027, was launched in February. With a budget of over 63 million dollars, it is expected to benefit 300 cooperatives in 27 municipalities in the four eastern provinces where coffee production is concentrated.

This joint project of the International Fund for Agricultural Development (IFAD) and the Ministry of Agriculture is aimed at strengthening the cocoa and coffee value chains and includes a gender approach by encouraging the inclusion of women in agroforestry activities.

Biogas Production Awaits Greater Incentives in Cuba — Global Issues

Farmer Mayra Rojas says that the Chinese-type fixed-dome biodigester built in back of her home in Carambola, in the municipality of Candelaria in western Cuba, has become part of her daily life and a key factor in improving her family’s quality of life. CREDIT: Jorge Luis Baños/IPS

  • Inter Press Service

“Biogas is a blessing,” says Rojas, a farmer who lives in the rural community of Carambola, in the municipality of Candelaria, located about 80 kilometers from Havana in the western province of Artemisa.

A pioneer in the use of this form of renewable energy in her town, she explains that with biogas “I spend less time cooking and pay less for electricity,” while the savings have enabled the gradual upgrade of her old wooden house to a more solid cinderblock structure.

In addition, “it doesn’t blacken the pots, like when I used firewood. And now I get my nails done and they last, as does my hair after I wash it,” says the environmental activist who raises awareness about caring for nature among elementary school children, in an interview with IPS at her farm.

She also specifies that greater support from her husband and two children in household chores, cleaning the yard and taking care of the animals on the family farm, “and greater awareness of environmental care,” are other benefits brought about by the use of this alternative energy.

In fact, it was her husband, Edegni Puche, who built the biodigester, for which the family put up part of the cost, while receiving contributions from the municipal government and the local pig farm company.

At the back of the house are the pigsties where they raise pigs, as well as fruit and ornamental trees, while on an adjoining lot Rojas is setting up an organoponic garden, where she will grow different vegetables.

As she pours the freshly brewed coffee, she says that “before, when the pens were cleaned, the manure, urine and waste from the pigs’ food accumulated in the open air, in a corner of the yard. It stank and there were a lot of flies.”

But in 2011 she learned about the potential of biodigesters, where organic matter is decomposed anaerobically by bacteria, but in a closed, non-polluting environment that provides gas as an energy resource.

Training workshops and advice from specialists from the Cuban Society for the Promotion of Renewable Energy Sources and Respect for the Environment (Cubasolar) and the Movement of Biogas Users (MUB) encouraged people to build biodigesters, Rojas said.

Founded in 1983, MUB brings together some 3,000 farmers who use the technology in this Caribbean island nation of 11.1 million inhabitants.

An incentive to expand biogas in Cuba was provided by the international Biomas-Cuba project, which began in 2009 and is due to finish this year, focused on helping to understand the importance of renewable energy sources in rural environments, the role of biodigesters on farms and in waste treatment systems on pig farms, among other objectives.

With funding from the Swiss Agency for Development and Cooperation (Cosude), the initiative is coordinated by the Indio Hatuey Experimental Station, a research center attached to the University of Matanzas in western Cuba, and involves related institutions in several of the country’s 15 provinces.

Methane, from enemy to ally

Experts agree that the proper management of biological methane resulting from the decomposition of agricultural waste and livestock manure can generate value and be a cost-effective solution to prevent water and soil contamination.

As a potent greenhouse gas, methane has 80 times the warming power of carbon dioxide, according to studies.

Therefore, its extraction and use as energy, especially in rural and peri-urban environments, can be a solution for reducing electricity consumption and for helping to combat climate change.

More than 90 percent of Cuba’s electricity generation is obtained by burning fossil fuels in aging thermoelectric plants and diesel and fuel oil engines, which pollute the air and contribute to global warming.

There are an estimated 5,000 biodigesters in Cuba, in a nation where a significant percentage of the 3.9 million homes use electricity as the main energy source for cooking and heating water for bathing.

“We have to make people more aware that the biodigester not only protects the environment and provides energy, but also brings savings, because the manure that is not used is money that is thrown away,” says Rojas.

It also provides biol and biosol, liquid effluent and sludge, respectively – end products of biogas technology that are rich in nutrients, ideal for fertilizing and restoring soils, “as well as watering and keeping plants green,” says Rojas as she proudly shows the varieties of orchids in her leafy yard.

Her biodigester has also proven its usefulness to the community, because when there are blackouts due to tropical cyclones that frequently affect the island, “neighbors have come to heat up water and cook their food,” she adds.

Obstacles

Rojas says that a major impediment to the spread of biodigesters in local communities and the country is the island’s economy, whose three-decade crisis was aggravated by the COVID pandemic and the tightening of the U.S. embargo.

The decapitalization of the main industries and financial problems are major factors in the low levels of production of cement, steel bars, sand and other elements used to make biodigesters, which are also necessary to reduce the high housing deficit and fix the portion of homes that are in poor condition.

The availability of manure is another stumbling block with a deficient pig and cattle herd, which will have to wait for the most recent government measures aimed at stimulating their growth and balancing it with domestic demand for meat to take effect.

“I received the support of the municipal government, the local pig company, plus the technical advice from Cubasolar” to build the six-cubic-meter Chinese-type fixed dome biodigester, explains Rojas. “But not all families have enough animals or can afford to build one.”

Perhaps that is why in Carambola it is only possible to find five biodigesters in a community of about 120 homes and 400 local residents, she added.

“Building a biodigester has become too expensive,” acknowledged Lázaro Vázquez, coordinator of Cubasolar in San Cristóbal, a municipality adjacent to Candelaria, who provided advice for the construction of the one on the Rojas farm, which is considered small-scale (up to 24 cubic meters per day).

Although costs depend on factors such as the size, type and thickness of the material, and even the characteristics of the site, specialists estimate that the average minimum cost for the construction of a small-scale biodigester cooker for household use is around 1,000 dollars, in a country with an average monthly salary of about 160 dollars at the official exchange rate.

Vázquez told IPS that low-interest loans should be made available, because “it will always be more economical to make biodigesters using domestic products.”

He pointed out that in Cuba “there is potential” to expand the network of biodigesters, which could reach 20,000 units, at least small-scale ones, according to conservative estimates by experts.

Biogas, circular economy and local development

During a Jul. 21 session of Cuba’s single-chamber parliament, economic stimulus measures were announced, including an aim to increase the production and use of biofuels and biogas.

“Although it can be used in transportation…the main benefit of the biodigester is environmental and the efficiency of biogas lies in its final use,” José Antonio Guardado, a member of Cubasolar’s National Board of Directors and coordinator of MUB, explained to IPS.

In this regard, Guardado reflected that the direct use of biogas for cooking is much more efficient than if it is transformed into electrical energy or used to power a vehicle.

The head of MUB recommended “understanding the value of biogas technology in a comprehensive manner, taking advantage of all of its end products. This includes the supply of basic nutrients for soil fertilization that has a direct impact on food production.”

This would contribute to the closing of cycles of the circular economy, based on the principles of reduce, recycle, reuse, which promotes the use of green energies and diversification of production to achieve resilience.

“Evidently this final product, from biogas technology, will only be achievable locally, with the participation of all the actors of the Cuban economy, and social inclusion,” Guardado said.

Ministerial Order 395, issued in 2021 by the Ministry of Energy and Mines, stipulated that each of Cuba’s 168 municipalities must have a biogas development program and strategy, and must coordinate their management and implementation with their respective provinces.

The appointment of a government official to head the commission, to prioritize the allocation of materials to build biodigesters, seems to confirm the authorities’ decision to promote sustainable energy development from the local level.

Cuban Farmers Fight Land Degradation with Sustainable Management — Global Issues

Farmer José Antonio Sosa, known as Ché, stresses the importance of taking into account the direction of the land for planting, and the use of live or dead barriers to prevent rains from washing away the topsoil to lower areas, thus combating soil degradation in Cuba. CREDIT: Jorge Luis Baños/IPS

  • Inter Press Service

“The land was a mess, covered with sweet acacia (Vachellia farnesiana) and sickle bush (Dichrostachys cinérea), with little vegetation and many stones. People asked me how I was going to deal with it. With an axe and machete I gradually cleared the undergrowth, in sections,” Sosa told IPS.

Now there are plots of different varieties of fruit trees, vegetables and tubers on the 14 hectares that this farmer received from the State in usufruct in 2010, as part of a government policy to reduce unproductive land and boost food production.

The crops feed his family, while contributing to social programs and sales to the community, after part of the produce is delivered to the Juan Oramas Credit and Services Cooperative, to which the farm located in the municipality of Guanabacoa, one of the 15 municipalities of the Cuban capital, belongs.

On the farm, where he works with his family and an assistant, Sosa produces cow and goat milk, raises pigs and poultry, and is dreaming of farming freshwater fish in a small pond in the not too distant future.

La Villa is in the process of receiving “sustainably managed farm” certification. The farm and Sosa represent a growing effort by small Cuban farmers to recuperate degraded land and use environmentally friendly techniques.

The restoration of unproductive and/or degraded lands is also connected to the need to increase domestic food security, in a country highly dependent on food imports, whose rising prices mean a domestic market with unsatisfied needs and cycles of shortages such as the current one.

At the end of 2021, Cuba had 226,597 farms, 1202 of which had agroecological status while 64 percent of the total – some 146,000 – were working towards gaining agroecological certification, according to official statistics.

Sosa, who has been known as “Che” since he was a child, said the use of natural fertilizers and animal manure has made a difference in the recovery and transformation of the soil.

“It is also important to pay attention to the way crops are cultivated or harvested, to avoid compaction,” the farmer said.

Studies show that changes in land use, inadequate agricultural practices (including the intensive use of agricultural machinery and irrigation), the increase in human settlements and infrastructure and the effects of climate change are factors that are accelerating desertification and soil degradation in this Caribbean island nation of 11.2 million people.

Sosa stressed the importance of paying attention to the direction of the land for planting, and the use of living or dead barriers “to prevent the water from carrying the topsoil to lower areas when it rains.”

Drought and climate change

In this archipelago covering 109,884 square kilometers, 77 percent of the soils are classified as not very productive.

They are affected by one or more adverse factors such as erosion, salinity, acidity, poor drainage, low fertility and organic matter content, or poor moisture retention.

The most recent statistics show that 35 percent of the soil in Cuba presents some degree of degradation.

But at 71 years of age, Sosa, who has worked in the countryside all his life, has no doubt that climate change is hurting the soil.

“The rain cycles have changed,” Sosa said. “When I was young, in the early 1960s, my father would plant taro (Colocasia esculenta, a tuber that is widely consumed locally) in March, around the 10th or so, and by the 15th it would be raining heavily. That is no longer the case. This April was very dry, especially at the end of the month, and so was early May.”

He also referred to the decrease in crop yields and quality, “as soils become hotter and water is scarcer.”

Several studies have corroborated important changes in Cuba’s climate in recent years, related to the increase in the average annual temperature, the decrease in cloud cover and stronger droughts, among other phenomena.

According to forecasts, the country’s climate will tend towards less precipitation and longer periods without rain, and by 2100 the availability of water potential could be reduced by more than 35 percent.

But more intense hurricanes are also expected, atmospheric phenomena that can discharge in 48 hours half of the average annual rainfall, with the consequent stress and severe soil erosion.

Although the least productive lands are located in the east, and Cuba’s so-called semi-desert is limited to parts of the southern coast of Guantánamo, the easternmost of the 15 provinces, forecasts indicate that the semi-arid zones could expand towards the west of the island.

Goals

In addition to being a State Party to the United Nations Convention to Combat Desertification, since 2008 Cuba has been promoting the Program for Country Partnership, also known as the National Action Program to Combat Desertification and Drought; Sustainable Land Management.

Likewise, the Cuban government is committed to the 2030 Agenda and its 17 Sustainable Development Goals (SDGs), agreed within the United Nations in 2015.

In SDG 15, which involves life on land, target 15.3 states that “By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world.”

According to Sosa, the increase in soil degrading factors requires more efforts to restructure its physical and chemical characteristics.

In addition, he said, mechanisms should be sought to prioritize irrigation, taking into account that many sources are drying up or shrinking due to climate variability.

“In my case, I irrigate the lower part of the farm with a small system connected to the pond. But in the higher areas of the farm I depend on rainfall,” he said.

The construction of tanks or ponds to collect rainwater, in addition to the traditional reservoirs, are ideal alternatives for this Caribbean country with short, low-flow rivers and highly dependent on rainfall, which is more abundant during the May to October rainy season.

But farmers like Sosa require greater incentives: there is a need for more training on the importance of sustainable management techniques, and for economic returns, as well as financial and tax support, in order to make agroecological practices more widespread.

In 2019, Cuba approved the National Land Degradation Neutrality Target Setting Program.

“The guideline foresees implementing new financial economic instruments or improving existing ones by 2030 in order to achieve neutrality in land degradation,” Jessica Fernández, head of the Climate Change department of the Ministry of Science, Technology and Environment, told IPS.

The plan is to enhance the use of credits, insurance and taxes as economic incentives for farmers, based on soil improvement and conservation, and to account for the current expenses destined to environmental solutions to determine the total expenses for soil conservation, the official added.

“We are in talks and studies with the Central Bank of Cuba to gradually introduce green banking,” Gloria Gómez, director of natural resources, prioritized ecosystems and climate change at the ministry, told IPS.

“This service will seek to promote and finance projects that provide solutions to environmental problems through loans with lower interest rates, longer repayment periods, incentives for green products and services, or eco-labeling,” she said.

Since 2000, the Ministry of Agriculture has been developing the National Program for Soil Improvement and Conservation, and in January the Policy for Soil Conservation, Improvement and Sustainable Management and Fertilizer Use came into effect.

At the same time, the Cuban State’s plan to combat climate change, better known as Tarea Vida, in force since 2017, also includes actions to mitigate soil vulnerabilities.

In the last five years, the principles of Sustainable Land Management (SLM) were applied to more than 2525 hectares, while one million of the more than six million hectares of agricultural land in the country received some type of benefit, statistics show.

Other national priorities are related to increasing the forested area to 33 percent, extending the areas under SLM by 150,000 hectares and improving 65 percent of agricultural land by the end of the current decade.
