To understand how high-frequency radio community networks were developed in the Brazilian Amazon, it is important to reflect on the geographic characteristics and historical and socioeconomic background of Brazilian Extractive Reserves. By drawing on these factors we explain the novelty of our technical solution – building local autonomous connectivity in the Amazon rainforest using digital radio in the high-frequency band – and how it is the most appropriate solution in this context. We put into perspective aspects of available infrastructure and the local context as the main factors defining the solution that can best serve the needs and wishes of the local population to provide information and communication solutions.
Socioeconomic and historical background
The Amazon region, which extends through many South American countries, is one of the least developed in terms of information and communication technology (ICT) infrastructure, as in these areas there is insignificant investment in infrastructure. For many communities here the only available communication technology is the high-frequency radio transceivers that are practical and affordable and have already been in use for decades.
Although the first Amazon digital radio network using the high-frequency radio band in the Brazilian Amazon forest was created in the state of Acre in 2014-2015, high-frequency radio transceivers – bi-directional radio transceivers that allow communication directly between the two transceivers without any intermediate points – existed and were used by the local population for a long time before that. Locals remember the use of high-frequency radio transceivers by the patrãos (bosses) who owned and managed the rubber plantations in Brazil. Until the early 1980s, the seringueiros (rubber tappers) were the many generations of migrants from the Northeast region of Brazil, along with some indigenous people populating the Amazon rainforest who were often enslaved and forced to work in the rubber tapping industry. Looking to end this oppression and hardship, rubber tappers mobilised with the labour movement and with environmentalists. This led to the liberation of rubber tappers and the establishment of the first (legally recognised) extractive reserve in the Brazilian Amazon in 1990 – the Alto Juruá Extractive Reserve. As a result of this struggle, rubber tappers claimed their right to live, work and organise their lives themselves on the land where previously they were forced to work in harsh conditions.
Geography of the Alto Juruá Extractive Reserve
The Alto Juruá Extractive Reserve is located in the state of Acre, on the border with Peru, and comprises an area of 506,000 hectares of forests and rivers. It is a federal administrative territory set up as a natural conservancy that allows traditional communities to live and earn their livelihoods, including through natural resource extraction, inside the conservation zone, based on the assumption that their traditional way of life favours and enhances the protection of natural areas. Therefore, inhabitants can live from the land and rivers of the extractive reserve; however, they also face the need to find sustainable ways of farming and maintaining their lives inside the reserve without depleting the natural environment. This form of coexistence with the environment would guarantee protection of the forest and of the people living inside the reserve.
For years the main challenge for traditional and indigenous communities of the Amazon forest was being isolated and scattered throughout the forest on their own without any access to communication. The only available means of transportation is by rivers and there is no electricity power grid inside the reserve, which leaves people with the option of either gasoline-powered generators or solar energy. Therefore transportation and energy are expensive and not accessible for the majority of the extractive reserve population.
Precarious public infrastructure in the reserves also makes it almost impossible to access public services. For example, many families receive financial support from the government programme Bolsa Família, through which a monetary allowance is provided to the female head of the household for every child, on the condition that the children attend school. Schools in the extractive reserves are supposed to provide transportation for the children inside the reserve to bring them to school. In practice, however, this often does not work, and instead children are staying at home. This has a direct effect on girls in particular: without any primary education they have no option of continuing their education or being employed outside of their immediate surroundings, and are left with the only choices of early marriage (at the age of 13 or 14) or staying at home to look after the children and the household.
Today Amazon rainforest reserves are endangered. With massive territories without any oversight or protection from the army or state, extractive reserves represent an easy target for illegal extractive activities, such as logging, hunting, and the mining of precious metals and other natural resources like oil. After the decline of the rubber tapping industry in Brazil, rubber tappers also needed to find ways of sustaining their lives inside the reserve, and recently many have opted to leave for urban areas in hope of better lives and jobs.
All of these aspects were taken into consideration when our community work began. There was a clear need for a means of communication and information technology that could help locals monitor their territory, mobilise and coordinate their actions, exchange information with the municipal centre and receive assistance with basic services like health care and education. Taking into consideration the lack of any infrastructure and the long distances between communities separated by an impenetrable rain forest and their expressed wishes to use radio transceivers, the solution for community connectivity in this context was to build an autonomous, affordable solution for connectivity using old, existing infrastructure.
The Amazon high-frequency digital radio network in Acre
A high-frequency digital radio network as a solution to provide community connectivity has been implemented and is currently operating in the Brazilian Amazon forest in two states: in the Alto Juruá Extractive Reserve in Acre and in the Terra do Meio region in Pará state.
The Alto Juruá Extractive Reserve has a network of seven radios inside the reserve and one main hub-station in the city of Marechal Thaumaturgo. This network is a result of a long-term collaboration that started in 2013 between traditional and indigenous communities in Acre, and researchers and professors from the University of Brasilia, Sao Paulo State University and University of Campinas. The network was developed as part of the academic research project “Fonias Juruá” to provide information and communication infrastructure to rural Amazon communities that are under-served by regular and commercial information and communication networks. It was based on the requests for two-way voice radios from 24 traditional communities in the Alto Juruá Reserve and aimed at engaging locals in the process of political participation and empowerment through joint sustainable experience. At the moment the estimated number of users is around 500 people.
It took four years from the beginning of talks with the community to purchasing equipment and taking the first trip to the extractive reserve where the first six radio stations were installed with the collaboration of community leaders and locals living inside the community. Five of the radios were installed inside the extractive reserve and one station was installed in the city of Marechal Thaumaturgo, which served as a hub to connect and exchange information between all the stations. The idea was that Marechal Thaumaturgo would provide socially and politically important information and news to the extractive reserve that would serve as an incentive to foster communication and the exchange of information inside and outside of the reserve. It was also necessary for people living inside the reserve to talk to their relatives living in the city of Marechal Thaumaturgo, exchange information about local production and prices of goods and services, ask for medical assistance and advice about social services, and access other locally important information. Another important aspect of communication was to report illegal activities taking place in the reserve, such as illegal logging, hunting and mining.
Today the Acre high-frequency radio network is composed of eight two-way radios – a point-to-multipoint broadcasting set-up allowing every station in the network to receive the transmission and to communicate among each other. This system is autonomous, low maintenance and easy to use by any member of the community after basic training. The solution is composed of standard high-frequency transceivers, common wire horizontal dipole antennas that are positioned to work in near vertical incidence skywave (NVIS) mode, and software-defined radio (SDR) techniques for digital communications. As there is no power or electricity infrastructure available, each radio station is powered up by a solar panel and batteries, making it an environmentally friendly set-up.
Since its inception the network has been in regular use by the local communities without any major problems. In 2016 we successfully accomplished trials with a digital transmission system based on the Digital Radio Mondiale (DRM) standard (this was first attempted in 2015 but was only partially successful). The solution for digital transmission is made up using an embedded computer, an interface to the radio and the SDR software. We managed to send text files and images over the radio in the 80-metre HF band (3545 kHz) to locations 100 km apart.
Comparing the two networks: A look at the Terra do Meio Digital Radio Network
The network in the state of Pará has no formal name, but we refer to it here as the “Terra do Meio Digital Radio Network”. The network operates with a main station set up at the NGO Instituto Socioambiental (ISA), with other independent stations (around 10 stations) in the urban area of Altamira that provide special services and communication. In the rural area of the Amazon forest there are at least 50 stations, meaning that, like the Fonias Juruá network, this network can be considered predominantly rural. The network has been set up by ISA, SDR Telecom (a company founded by a member of the Fonias Juruá Project) and the local people of the Terra do Meio region. The network has more than 4,000 users.
In comparison to the Acre community network, the Terra do Meio Digital Radio Network is significantly larger, with around 60 radio stations spread across the region. The Terra do Meio region is also bigger and therefore the network connects many more communities, creating a high demand for radio use. The daily use of radios is vital to the local population. For example, in some cases when people are travelling to another place in the region they take their radios with them and upon arrival they assemble the radio to be able to talk. At one meeting we witnessed a queue of people waiting to use the radio to talk to their relatives and acquaintances, for personal or business reasons. This potential of the network would not be possible if the network was small. As a result, the size of the network plays a significant part in its usefulness.
Despite the very similar social and geographic contexts, the way the two networks operate is also different in terms of ownership (the way the radios are owned and shared), as well as the economic incentive to use the radios. Here the economic capacity of community members plays a defining role in the ways the radio network develops and extends inside the forest territories, as well as how community members attribute importance to the use of radios. From our observations we can say that in Pará, the use of the network is more economically motivated. People in the communities run daily business over the radios and therefore use it more regularly and more frequently. This factor appeared to impact on the maintenance of the network.
In Acre we observed only one community where the maintenance of the radio was given importance by the members of community, as opposed to the maintenance support received from the project team. In this community, the head of the household where the radio station was installed had a personal interest in maintaining the station because he was using it for running his own business – in other words, there was an economic incentive. He purchased a new battery at his own expense to keep the radio working when the initial one broke down. This suggests that networks that enable the economic agency of communities have a stronger prospect for sustainability.
There is a clear division of labour in the Alto Juruá Extractive Reserve that was established throughout the years and was defined by the way of life inside the reserve. Most hard physical work like hunting and farming is done by men, whereas women tend to stay at home to cook and take care of the family and the household. However, when it comes to the decision-making process, women take equal part and participate actively.
When one community had a meeting to decide and vote on the house where the radio would be installed, one woman openly voted against her husband when he proposed to have the radio in their house. In another community women were very proactive at the community meeting, expressing their concerns and asking questions. They became so engaged that they even participated in the process of installing antennas and helping to dig holes and install wooden posts along with men – something that only men did in other communities. The first volunteers to test and use the radio were teenage girls, who appeared less shy than some of the young men who resisted using the radio for the first time in front of everyone else.
Because they tend to take care of household duties, women naturally stay closer to the radio during the day and seem to be more keen to talk and share news with others compared to men.
