In 2025, Gran Tierra Energy opened the Acordionero Forestry Centre (AFC), a 185-hectare environmental innovation hub located in El Cairo village, Colombia a strategically important conservation zone in Cesar. It is Gran Tierra’s hope that AFC will play a key role in restoring forest corridors and preserving water bodies thar provide water to the surrounding communities. Nearly 11,000 native trees have already been planted at the Centre, reinforcing the Centre’s contribution to ecosystem recovery in the region. The AFC has also been designed to test and implement sustainability efforts aimed at long-term environmental resilience and regional economic development.

The Centre is located between two interconnected, biodiverse forested areas, through which more than 100 bird species have been recorded travelling. The location allows the Centre to restore forest corridors and preserve river-based water sources for nearby communities.  The AFC also includes a forest nursery for the restoration of native species of plants and trees. Currently, the nursery is producing approximately 9,000 plants per month, that are used to conserve the surrounding forest and are being donated to local families.

Aquaponics

At the heart of this innovation hub is a solar-powered aquaponics system that merges fish farming with hydroponic plant cultivation in a closed-loop system. GTE and local community members are testing innovative aquaponics systems as part of a broader effort to explore sustainable agriculture models that could enhance environmental and economic resilience in the region. The aquaponics system accelerates food production, with a small land footprint, and has the goal of increasing food security and lowering food costs for families in the region. Nutrient-rich water from tilapia tanks is used to irrigate and fertilize crops such as basil, cherry tomatoes, lettuce, and aromatic herbs—without the need for soil or chemical pesticides. The system recycles water continuously, achieving over 90% water savings compared to conventional agriculture, and is powered by solar energy to ensure operational efficiency and a low environmental impact.

Meliponiculture (Stingless Bees)

The AFC also includes a meliponiculture initiative that plays a key role in biodiversity conservation by protecting and reproducing native stingless bees—essential pollinators that support the health and regeneration of local ecosystems. These bees assist in the pollination of both native forests and cultivated plantations, helping sustain biodiversity and agricultural productivity. The initiative is also promoting environmental education by raising community awareness about the ecological importance of bees, while creating opportunities for local businesses in the production of high-value medicinal honey and honey-based products. By protecting bees, the AFC is helping to safeguard entire ecosystems and secure a more sustainable future for the region.

Anaerobic Biodigesters

Within the ACF, GTE installed residential-scale anaerobic biodigesters, which is a system that treats wastewater organically and produces biogas, eliminating open sewage while providing energy that can be used for cooking. In many rural Colombian villages, untreated wastewater flows through open sewers, creating serious health and environmental risks—especially during the rainy season. At the same time, limited access to propane forces many households to rely on firewood, contributing to deforestation, air pollution, and causing significant adverse health effects. This technology demonstrates how thoughtful design can create lasting environmental, social, and economic impact.

Through the Acordionero Forestry Centre, Gran Tierra Energy continues to lead in environmental responsibility, by combining reforestation, water conservation, and community-driven initiatives to strengthen Colombia’s ecosystems and support local families.

“The Acordionero Forestry Centre has allowed us to see how we can work our land in a more efficient and sustainable way. With hydroponic pilot projects we have seen first-hand how, with a small portion of land, we can grow different crops in less time and with a significant increase in the volume. I´m sure that this could change the way we live and we could spend less money on food and accelerate the production of our crops.”

The Costayaco Forestry Centre (CFC) has become one of the most innovative reforestation efforts in South America that has grown to 335 hectares, located near the Company’s production facilities in Putumayo. Established in 2010 in coordination with regional environmental regulator Corpoamazonia, the facility has grown into a significant habitat for butterflies, birds, large felines and other wildlife.

The Centre is strategically located in an important environmental corridor connecting the Andean foothills and Amazonian Forest ecosystems, serving as a focal point for the Company’s compensatory requirements as well as many of its voluntary environmental activities. After 15 years, the Company has achieved its long-term goal of connecting the foothills to the Amazon. The Centre, which was officially designated as a protected habitat and has been replicated around the country, also serves as a hub for nearby communities, hosting educational sessions, presentations and briefings.

A Source of Seedlings for Reforestation

The Forestry Centre has cultivated hundreds of thousands of seedlings providing local communities the capability to reforest their land with native trees. Residents have begun planting seedlings on their land, which over the years had been degraded by agriculture, animal husbandry, and other industries that damaged the natural habitats and sensitive ecosystems. The Centre is located in close proximity to the Sacha Wasi nursery which has the capacity to produce over one million seedlings each year as part of NaturAmazonas.

A Space for Learning

The Forestry Centre functions as a community learning space with programming for both youth and adults. Visitors can learn about GTE’s operations and environmental stewardship activities. The Centre has welcomed government officials, scientists, community members, companies, academic institutions, students and is open to all.

Monitoring the Restoration of Animal Life

Corpoamazonia in partnership with GTE has installed over 100 cameras in the protected area surrounding the Costayaco Forestry Centre. The motion sensor cameras and monitoring stations have successfully identified 121 species of birds, 15 species of amphibians and 11 mammal species. This is a significant increase from the last wildlife monitoring program in 2016, which shows that the Company’s conservation and reforestation efforts are restoring these natural habitats and attracting wildlife back to these regions.

For example, six different feline species now call the Costayaco Forestry Centre home. This is because of a partnership between Corpoamazonia and GTE to focus specifically on wild cat conservation in the area. By establishing dedicated corridors and restoring the native canopy, this initiative ensures that these felines have interconnected habitats and the natural shelter required to thrive.

“I was here years ago when we planted seedlings about 50 centimetres tall. Today, those trees are nearly 20 metres high. Seeing a restoration area become a real forest is something you don’t forget.”

NaturAmazonas, the flagship conservation program started by GTE and Conservation International, has grown into an alliance of public and private institutions working together to address the root causes of deforestation. It works to develop solutions for reversing the process, while increasing the well-being of nearby communities.

GTE’s program has grown into a joint effort between the Colombian Ministry of the Environment and Sustainable Development, regional environmental agency, Corpoamazonia, and NGO Conservation International which oversees the project. The overall objective is to create the conditions required to protect and conserve Colombia’s Amazonia region by planting millions of trees and conserving land to restore important forested lands, helping residents live and work in greater harmony with the forest, and fostering partnerships amongst the institutions needed to effect long-term change at scale. Over the past 10 years this initiative has strengthened the mechanisms needed for sustainable reforestation, agricultural development and large-scale conservation including:

• Bringing numerous public and private institutions under an established framework to collaborate and increase their combined impact.
• Increasing knowledge of, and respect for, the value of forested areas.
• Implementing mechanisms for people and communities that reside in the area to make a sustainable living in harmony with nature.

Over the past eight years, this USD $18 million initiative has reforested and ecologically restored over 2,100 hectares of land and has attracted additional partners interested in moving this revolutionary program forward.

Agroforestry Centres

The Guayuyaco Agroforestry Centre in the town of Piamonte was converted and refurbished from an abandoned social site of a nearby Indigenous Inga community and is capable of growing over one million seedlings each year to support the reforestation initiative. Women from Miraflores and the surrounding areas carry out planting work at the Guayuyaco Agroforestry Centre. Cacao seedlings are spliced together to develop high quality and resilient varieties of the crop.

The Sacha Wasi Agroforestry Centre located in El Mesón, Villagarzón has a production capacity of one million seedlings per year, a total area of 8.06 hectares, and is designed with spaces to store materials, equipment and supplies. This agricultural-focused nursery includes specific areas for preparation and bagging of the substrate, irrigation, germination, management and sowing modules.

Sustainable Cacao Production

A central premise of NaturAmazonas is that durable conservation must be linked with local economic opportunity. Organic cacao agroforestry and stingless beekeeping (meliponiculture) are two complementary activities supporting forest protection and household income. Cacao agroforestry simultaneously restores tree cover and provides long-term earnings for families, while native stingless bees pollinate cacao and other crops, strengthening ecosystem health and creating additional jobs. Families participating in cacao, conservation, and meliponiculture programs receive technical training and materials to build sustainable livelihoods while contributing to the protection of the Amazon.

Knowledge Generation

Local residents were hired for expeditions deep into the Piedmont, collecting and categorizing over 10,000 specimens of native plants. They are referred to as Guardians of Botanical Knowledge and they build their knowledge about the native plants and contribute to the creation of important mapping of the botanical make-up of the forest in their areas. Previously unknown plant species have been discovered by the Guardians.

So far, 27,000 specimens have been collected and processed, 1,404 of species have been identified, two of which are new for Colombia and over 130 people have directly benefited from the project.

Botanical Health Development Through Beekeeping

Thousands of bees swarm around unprotected beekeepers, who are not concerned because these are stingless bees, native to this part of the Amazon rainforest. It had previously been illegal in Colombia to cultivate stingless bees, but Gran Tierra worked with the Colombian authorities to change the regulations to allow local people to engage in this important line of sustainable production through the Company’s NaturAmazonas program. With 6,000 hives pollinating 24,000 hectares of plants and trees, supporting reforestation and contributing to botanical health, the bees are also producing honey for the farmers—a valuable, durable commodity with appeal in both local and national markets.

There is a high demand for stingless bee syrups, which have a number of different flavours, and keepers can also rent the bees out to local farmers for pollination, providing yet another stream of income. The association of beekeepers continues to grow, with 425 current members having been trained and certified.

“Buying a family farm was our dream. My husband’s work gave us the chance to save and make it real. Then NaturAmazonas helped us start with organic cacao, and little by little, our life here began to change.”
