Yunia Cancio cooked with firewood until a few years ago, when a biodigester was built on her family’s El Renacer farm in Cabaiguán, a municipality in the central Cuban province of Sancti Spíritus, under the Biomass Cuba project. That change meant a lot for her family’s quality of life, but it was not the only one.

“Life has improved a lot thanks to the biodigester, especially for me, because as the woman of the house I’m the one who cooks,” the 48-year-old farmer told IPS by phone from her family farm. “It’s a very clean fuel, more comfortable and safer, everything is more hygienic. Before I used to cook everything with firewood and my day-to-day workload was harder.”

She explained that using the biogas she normally cooks for 10 people a day and for 20 during the planting and harvest seasons, when the tobacco farm employs more workers.

Cancio and her family are among the residents of agricultural localities involved in Biomass Cuba, a project initiated in 2009 with funding from the Swiss Agency for Development and Cooperation (SDC), which is currently in its third stage and is to be completed in 2022.

According to Leidy Casimiro, a professor at the University of Sancti Spíritus and an expert with Biomass Cuba, in its different facets of renewable energy, training and agroecology, the initiative directly benefits more than 15,000 people, including 5,417 with biogas technologies.

The initiative is coordinated by the Indio Hatuey Experimental Station, a research centre attached to the University of Matanzas in western Cuba, and also involves related institutions in the eastern provinces of Guantánamo, Santiago de Cuba, Granma and Holguín, and the central provinces of Las Tunas and Sancti Spíritus.

The biodigester at the El Renacer farm began operating on Jul. 15, 2014. “It was built by my father-in-law and brother-in-law, with the help of my husband and children, who carried bricks and made the mixture. With a capacity of nine cubic metres, it was built under the supervision of Alexander López, an expert in biodigesters,” Cancio said.

She also explained that electricity savings have been significant on the 28-hectare farm where her family has long-term “usufruct rights” and where they raise pigs and a few head of cattle and grow tobacco, vegetables and fruit.

“Something really important was when we received a rice cooker that was powered by biogas, a wonderful thing that we hadn’t seen before; we enjoyed it very much,” she recalled when commenting on the changes brought by the biofuel.

The plant also created new routines. Since it is fed mainly by manure from the farm’s pigs, the biodigester is connected to the pigsties. From time to time, cow manure is added to make the biogas more potent, from the stables, which are farther away.

According to Giraldo Martín, national director of Biomass Cuba, “The results are very valuable because today we have farms that consume only 30-40 percent of the conventional energy they used before.”

In a telephone interview with IPS from the municipality of Perico, in the province of Matanzas, Martín explained that in all its stages, Biomass Cuba has provided technologies and created capacities so local residents could move towards the concept of agroenergy in rural areas.

He also mentioned the covered lagoon model, an industrial technology that treats large quantities of biological waste to provide high volumes of biogas on a daily basis, which may be used in the future to generate electricity for the national power grid.

“In social terms, Biomass has had a great impact in the communities where it has intervened, generating employment, producing food, and in Cabaiguán, receiving domestic fuel through the supply networks that conduct biogas from pig farming areas to homes, with social and environmental benefits,” Martín said.

“We have farms that use the solid and liquid waste from the biodigesters as an excellent fertiliser with abundant nutrients that also contributes to the recovery of degraded soils, which are widespread today in agricultural areas in Cuba,” he explained.

Cancio said these techniques are used on her family’s farm, where the effluent from the biodigester “is used to fertilise the farm’s organoponic crops, including varieties of vegetables, herbs and medicinal plants, and fruit trees.”

“We are diversifying and…we now have infrastructure to extract oils, add value to various products, obtain flour from our root vegetables (a staple of the Cuban diet), motivate us to improve consumption habits and create new recipes with things that we did not use before,” she said proudly.

However, the Biomass project has also had its setbacks.

Martín said that one of the barriers that Biomass has had to break down was the lack of understanding about the concept of treating animal waste and producing energy, something that has taken a great deal of explaining and “is still not completely worked out.”

He also considered it a challenge to align the priorities in the bidding and purchasing system with the plans of companies and productive and service organisations, so that the equipment acquisition processes are efficient and allow the technologies and knowledge generated by the projects to be applied expeditiously.

The project director said the main impact of the initiative was the way it influenced public policies.

Biomass contributes to “understanding the importance of renewable energy sources in rural areas, the role of the contributions that farms can make with biodigesters, waste treatment systems on pig farms, the use of rice husks to produce electricity and steam to dry rice, as well as the use of residual wood from sawmills to generate energy,” Martín said.

Meanwhile, José Antonio Guardado, national coordinator of the Movement of Biogas Users (MUB), told IPS that there are between 4,500 and 5,000 biodigesters around the country. “A count is currently being carried out in order to have a more precise figure,” he said by e-mail from Santa Clara, capital of the province of Villa Clara.

The MUB, which brings together producers who use the technology of anaerobic digestion by the action of microorganisms, emerged in Cuba in 1983 and has 3,000 members throughout this Caribbean island nation.

Guardado said the most urgent task of this movement was the promotion of the closed cycle system.

“In our assessment, in less than five percent of the installed biodigesters, closed-loop criteria and concepts are used, which means that the surplus end products are used in the processes that are generated in the chain on the farm, such as fish farming, irrigation or fertilisation,” he said.

Guardado said the MUB and all other actors working on the issue at the local level should defend this technology until all existing biodigesters in the country are closed-loop, including the distribution of surpluses among neighbouring producers.

According to the Ministry of Energy and Mines, 95 percent of the national energy mix is made up of fossil fuels, while this year the generation of energy from renewable sources is expected to grow to 6.3 percent of the total energy produced in the country.

Cuba’s goal is for 24 percent of energy to come from renewable sources by 2030.

HAVANA, Jul 23 2013 (IPS)

“The basic objective of the Swiss Agency for Development and Cooperation (SDC) is people’s welfare, and I think that in this we have many affinities with what the Cuban government wants,” Regula Bäbler told IPS.

The SDC, which has been operating in Cuba for over a decade, provides cooperation in social and economic areas through development programmes in areas ranging from food security and climate change to housing, bioenergy and gender equality.

Globally, the SDC’s main focus in the 2013-2016 period will be on five programmes, in the areas of climate change, water, food security, health and migration.

“We work on these matters both globally and regionally, like for example adaptation to climate change in this region,” said Bäbler, who at the end of her mission in Havana summed up the SDC’s priorities, at the global and regional level, and in the case of Cuba in particular, in this interview with IPS.

Q: What is the result of the SDC’s cooperation with Cuba in the area of climate change, and what challenges will be faced over the next few years?

A: The framework for cooperation with Cuba for the 2011-2014 period is not explicit about this issue. However, in early 2011 the Swiss parliament approved extra financing for projects dedicated to climate change adaptation. That provided an important boost for Switzerland’s cooperation in all countries.

Thanks to counterparts who had already taken steps forward in this matter, we managed to support three projects. One was from the IPS (Inter Press Service) news agency, which approaches the problem from the media with a regional focus, called “Retos de la naturaleza: Cambio climático, mitigación y adaptación en el Gran Caribe” (Challenges of Nature: Climate Change, Mitigation and Adaptation in the Greater Caribbean).

In the concrete case of Cuba, another of these programmes made it possible for the city historian’s office to study climate change threats to the ‘malecón’ (seaside avenue), which stretches along several kilometres of the coastline in Havana.

And a third project involved a Habitat programme, to raise people’s awareness on climate change threats and how to adapt.

Q: The BASAL (Environmental Bases for Local Food Sustainability) project was the last one that the SDC financed in conjunction with the European Union. What aim does this programme have?

A: It’s a very ambitious project, and at the same time very simple, because it tries to get farmers to continue obtaining fruits from their labour despite climate change. Perhaps their yields will increase or improve, but the main objective is to maintain what farmers have now.

For now it covers three municipalities, although the idea is to extend it to 30. A central issue in this project is improving information on the changes underway and on how to adapt agricultural production to problems like the salinisation of soil, drought, or intense and unseasonal rainfall or more intense hurricanes.

Q: What sectors does the SDC’s cooperation target, in social matters?

A: In general, we think it’s necessary to uphold and ensure equality. It’s well-known that everyone has access to healthcare, education and the basics necessary for life (in Cuba). But we also observed – and we are not the only ones – that the changes proposed by the government itself could give rise to inequalities.

We feel a commitment to the people and groups who would be left at a disadvantage because they are not well-prepared to take advantage of the changes. In this sense, we support the municipalities in different projects so they will have the capacity to discover and open up possibilities for these sectors.

All of this without forgetting about gender equality, which for the SDC is an essential cross-cutting issue – in other words, every project must take into consideration how men and women will be affected, while working to ensure equal benefits.

This work also incorporates issues like the questions of masculinity and gender violence.

Q: What challenges has the process of updating the economic model, currently being carried out by the Cuban government, posed for international cooperation?

A: The work of cooperation is to support changes to improve people’s living conditions. For me it is clear that the Cuban government also wants that. In that sense, the process of updating the economy is welcome, and we want to support it.

We also know that these processes are complicated and require a great deal of adaptation and reorganisation by the institutions.

I understand that the country needs heavy financial investment, which doesn’t come from donors. But the bodies we work with think international cooperation brings ideas and impetus that are also important. Perhaps this would be a good foundation for dialogue with high-level government representatives.
