Development and Conservation

Safety for climbing and reaching açaí fruits, whether for consumption or trade, prevents people from cutting down these wild palms, helping to preserve them in the Bolivian Amazon.

The conservation of the Amazon and the productive development of those living deep within its forests now have a new ally: a “made in Bolivia” harness that allows açaí harvesters to climb trees over 20 meters tall with greater safety, promoting a multitude of social and environmental benefits.

The initiative was developed as part of the projects carried out by Conservación Amazónica, with support from experts in the use of climbing devices and specialists in harvesting wild fruits—the residents of Pando themselves.

“The harness is for the safety of the harvester and also to make them more comfortable during the harvest,” reported Abraham Poma from Conservación Amazónica.

The design was patented in 2021 with the National Intellectual Property Service (Senapi) as a “Safety Harness for Climbing Palm Trees,” according to Abraham Poma, a forest management specialist at Conservación Amazónica.

Currently, the patent for a second harness is being prepared. Derived from the first design, it is adapted for harvesting royal palm or majo, as its safety measures differ due to the thicker trunk.

The Need

Liliana Lorini, director of the local empowerment program at Conservación Amazónica, explained that this NGO works on productive development alongside local stakeholders, the inhabitants of natural forests.

They support them in their development processes, seeking ways to improve their situation while respecting and conserving the natural resources they live with daily.

“We work under a value chain approach, addressing four areas. The first is forest management, the second is transformation, the third is commercialization, and, crosscuttingly, we work on organizational strengthening. Within this value chain approach, we work with various chains that are utilized in the forest,” Lorini explains.

In this context, they realized that one way to ensure the development of wild açaí palms was to prevent them from being cut down for their fruit. These trees are slender, about 40 centimeters in diameter at maturity. Some learned to climb them to reach their clusters, while others simply cut them down to make the fruit fall.

The issue became more noticeable when the fruit gained popularity in city markets. It became commercialized, and more people sought it more frequently; the same happened with other Amazonian fruits.

Creation of the Harness

Continuing to “fell” the palm trees would have led to the depletion of açaí. Therefore, to work directly with natural resources “in the forest” and preserve them, technology and tools began to be developed alongside local producers, for instance, in Santa Rosa de Abuná.

“The safety climbing harness, designed to access forest resources, is part of a capacity-building program aimed at ensuring better utilization and safety, especially for harvesters,” said Lorini.

In 2018, the local population recognized the need to protect the palm trees and their fruits for better harvesting practices. This led to the initiation of the harness’s development in collaboration with Conservación Amazónica.

There, at the foot of the dense vegetation, especially young men would tie a sort of rope around their feet to hug the tree and support themselves as they climbed. Sometimes, they would place a rope over their shoulder, under their arm, to hold onto while they harvested the clusters. After obtaining the fruit, still hugging the trunk, they would slip.

Although there are very agile individuals, accustomed to these climbs and descents, using the friction of their arms or legs, and since the fruit weighed between 15 and 18 kilos, accidents were common. A fall from height could be fatal or leave the person with severe injuries and permanent damage.

“We saw the need to implement some technology, primarily for the safety of the harvester and also to make them more comfortable during the harvest, because this way they can use both hands,” commented Poma.

The harness allows them to be suspended, almost sitting, while using both hands to perform a good harvest without damaging the fruits or the bunch and without harming the tree.

However, before achieving the right model for this specific activity, the technicians had to create at least three prototypes, test them, redesign them, discard some parts, ensure good material quality, and gain approval from the community members, who would ultimately be the ones using it.

According to the technician, the metal rings or buckles were removed because they made the harness heavier. Initially, they made a waist model with straps for the legs, but there was still the risk that if someone slipped, they might flip over and fall out of the harness. So, they added additional straps to secure the shoulders, ensuring a more secure fit, so that the person would remain suspended but seated in case of a slip.

Benefits

With all the modifications and adjustments, the harness weighs just over a kilogram. This is important for the producer, as they must walk up to 10 to 15 kilometers for hours to reach the areas where the asaí grows, deep in the forest, in nature.

The straps are made of woven polyester and are five centimeters thick, making them more secure and firm. Its construction, also done in Bolivia, includes reinforcements and stitches that enhance the design’s sturdiness. All of this is thought out to ensure safety for the harvesters.

To date, according to the specialist, Conservación Amazónica has provided around 300 harnesses to the açai producers in Pando, who also participated in a long training and evaluation process to ensure the safe use of this equipment, teaching them to take care of the harness and the tools used with it, such as approved ropes for this work, while also promoting the conservation of the wild palm trees of the Amazon.

The New Model

The harness has been successful, which is why it was patented with all the required specifications to verify its effectiveness, scope, and, of course, to ensure that it had not been created before.

Now, the organization announced the completion of a new design, an adaptation of the first harness, which will be applied to the harvest of royal palm and majo, whose trunks are much thicker and require different tools.

For example, alongside the new harness, a longer rope loop and a type of pedals for foot support while climbing are necessary.

In search of empowerment for environmental care

For 14 years, Conservación Amazónica’s projects have focused on protecting this part of the planet, specifically in Bolivia.

For this reason, their work in the natural regions of Pando aims to foster societal empowerment towards the care of nature, according to Natalia Gil Ostria, the Strategic Communication Coordinator for the NGO.

“One of the areas where we’ve worked the most is the department of Pando, which has a forest in fairly good condition. This has been achieved thanks to the sustainable use of Amazonian fruits,” she commented.

She explains that, within the framework of the institutional vision, they work on creating conservation spaces, management, and developing plans to ensure their preservation.

“On the other hand, we focus on science and technology, which provide us with all the technological tools to carry out surveys of these areas, allowing us to assess the quality of resources and the condition of the territory,” she stated.

An essential aspect of all this work is the local population, with whom they develop local empowerment, providing tools so that people can engage in conservation efforts and better manage their surroundings.

“The focus, above all, is to make the most out of these fruits. I think it’s important for the general population to know that wild harvesting is happening, and that consuming these products, which we sometimes don’t see in the market, helps conserve the forest and keep it standing,” she said.
