Indigenous women-led Amazon reforestation takes root as Guajajara women established tree nurseries across seven Araribóia Indigenous Land communities.
Kariamora Santana watched rivers dry up, animals retreat, and forest health slowly deteriorate across the Araribóia Indigenous Land in Brazil’s Maranhão state. The midwife and matriarch of the territory never imagined the river would need help. But the time came. Now she leads alongside other Guajajara women, driving indigenous women-led Amazon reforestation through nurseries established across seven communities reversing decades of destruction from illegal logging, cattle ranching, and devastating fires.
The Araribóia Indigenous Land sits on the eastern edge of the Brazilian Amazon at a critical juncture. Scientists indicate the Amazon is approaching a tipping point that, once surpassed, would transition the tropical forest into a degraded savanna. In 2024 alone, fires caused in part by illegal logging and cattle ranching affected 70% of Araribóia territory, devastating ecosystems that Guajajara communities protected for generations.
Indigenous women-led Amazon reforestation emerged from this crisis through coalitions of Guajajara forest guardians. Working with Indigenous chief leaders, women established nurseries to remove struggling seedlings, revive them, and replant degraded areas with native trees. The approach combines ancestral knowledge of forest ecology with systematic restoration techniques addressing soil degradation, biodiversity loss, and water system decline.
Suluene Santana da Silva, a member of the Lagoa Quieta Indigenous Community, became president of Instituto Makarapy, a nonprofit focused on protecting biodiversity, appreciating traditional knowledge, and defending traditional peoples. Her community ties and ancestral knowledge facilitated partnerships between the institute and Indigenous chief leaders who coordinated nursery operations across the seven communities.
Suluene described how indigenous women-led Amazon reforestation extends beyond planting trees to restoring entire ecological relationships sustaining Guajajara life. Reforesting means bringing back trees, birds, animals, and rivers, revitalizing the forest together with the community rather than treating reforestation as purely a technical exercise disconnected from culture and community.
Health In Harmony, a planetary health organization and Rockefeller Foundation grantee, supports the Guajajara communities as reforestation efforts expand. The organization channels capital to local communities in rainforests across Brazil, Indonesia, Madagascar, and Panama, helping them protect and restore biodiversity and enhance carbon storage, water resources, and overall ecological health.
In Brazil, Health In Harmony works alongside Indigenous communities to improve direct financing through ethical nature-based solutions, including bio-credits and Indigenous-led carbon crediting. The organization’s Brazilian affiliate, SAMA-HIH, ensures that programming reflects community priorities identified through radical listening, a methodology that centers Indigenous peoples as true experts in stewarding their ecosystems.
Indigenous women-led Amazon reforestation through the Guajajara program demonstrates Health In Harmony’s broader model connecting community wellbeing with forest protection. The organization measures impact across carbon, biodiversity, and wellbeing indicators, ensuring communities leverage sovereign impact data for national and global advocacy to protect territories and finance their own solutions.

The Women’s Earth and Climate Action Network also supports Guajajara reforestation through its Reforestation and Forest Protection Program. This initiative addresses environmental and social challenges that Indigenous communities in the eastern Amazon face by improving soil quality, planting native trees, restoring biodiversity, and strengthening community and climate resilience through Indigenous women’s leadership and knowledge.
Guajajara women play crucial roles as guardians of ancestral lands. Their traditional knowledge of medicinal plants, forest ecology, seasonal cycles, and water systems provides a foundation for restoration that externally designed programs cannot replicate. Indigenous women-led Amazon reforestation succeeds because it draws on millennia of accumulated ecological knowledge passed down through generations of practice and observation.
Suluene emphasized that preservation extends beyond Indigenous territories. Efforts benefit everyone because the air, water, and ecological services generated within Araribóia reach far beyond community boundaries. This framing connects local indigenous women-led reforestation to global climate benefits, positioning Guajajara conservation as a planetary contribution rather than an isolated local initiative.
The Guajajara community gained international visibility at COP30 in Belém, Brazil, which featured the largest Indigenous participation in the conference’s history. Community members attended the summit, contributing to recognition that Indigenous knowledge and direct financing represent essential pillars for combating climate change. The conference acknowledged what Guajajara women demonstrate daily: that Indigenous-led conservation produces better outcomes than externally imposed models.
Indigenous women-led Amazon reforestation addresses threats extending beyond environmental degradation. Illegal loggers, miners, and agribusiness interests create direct opposition to Guajajara conservation work. Sonia Guajajara, born in the Amazon and appointed Brazil’s first Minister of Indigenous Peoples in 2023, elevated these struggles to national policy, giving Indigenous peoples unprecedented voice in protecting nature and shaping territorial rights.
Health In Harmony advances biodiversity monitoring and credit markets, emerging impact areas gaining global importance. By supporting Indigenous communities in generating and controlling their own impact data, the organization ensures that financial mechanisms for carbon and biodiversity credits benefit communities engaged in conservation rather than extracting value from them.
The initiative is supported by a coalition of partners including the Rockefeller Foundation, Instituto Makarapy, Pawanka Fund, Woodwell Climate Research Center, Health In Harmony’s Brazilian affiliate SAMA-HIH, and COCALITIA-MA, working alongside the Guajajara communities to advance reforestation, biodiversity monitoring, and territorial protection across the Araribóia Indigenous Land.
The nurseries across seven Araribóia communities represent more than reforestation infrastructure. They embody Guajajara women’s determination to restore ecological relationships disrupted by external exploitation. Each native seedling revived and replanted carries forward ancestral knowledge about which species belong where, how forests regenerate, and what healthy ecosystems require to sustain life for generations ahead.As Kariamora reflected, the time has come to help, to reforest, to respect, to care, because without care, everything disappears. Indigenous women-led Amazon reforestation through the Guajajara program demonstrates that the most effective conservation emerges when communities closest to forests lead restoration, drawing on ancestral wisdom to heal landscapes degraded by modern exploitation.
