Theonila Roka Matbob, a prominent environmental activist from Papua New Guinea, has been awarded the Goldman Environmental Prize for 2026, acknowledging her relentless efforts to mend the ecological and social damage inflicted by the now-defunct Panguna copper and gold mine. This crucial recognition highlights her role in advocating for her community in the Autonomous Region of Bougainville, which has suffered severe environmental consequences due to mining activities.
### A Legacy of Environmental Damage
Roka Matbob grew up in close proximity to the Panguna mine, operational from 1972 to 1989 under the management of Rio Tinto. Despite its closure, the mine has left a lasting scar on the local environment. The once-lush rainforest surrounding Roka Matbob’s home has largely been replaced by barren landscapes, prompting her childhood warnings to avoid the local rivers and soil, which have been rendered toxic.
“The mountains around me were mostly rock and sand,” she recounted, highlighting a stark contrast to the biodiversity that once thrived in the region. The exploitation of natural resources by foreign mining companies not only deprived the local community of its environmental heritage but also sparked a devastating civil war that claimed countless lives and left deep-rooted scars in the community.
### Activism in the Face of Adversity
Roka Matbob’s journey into activism began in her youth, fueled by a desire to hold the mining company accountable for the devastation caused. She became the lead complainant in a landmark human rights case against Rio Tinto, alleging the company’s negligence in addressing the environmental damages and human rights violations during the mine’s operation. Her campaign culminated in a landmark agreement with the company, and in 2024, Rio Tinto committed to a cooperative effort to remediate the environmental impact.
“Theonila is leading a historic effort to obtain justice for decades of environmental and social devastation,” praised Ilan Kayatsky of the Goldman Environmental Prize. Her relentless advocacy has galvanized support from local communities, fostering a coalition intent on advocating for Bougainville’s recovery.
In reflecting on her activism, Roka Matbob noted significant milestones that fueled her mission, such as when the Human Rights Law Centre began to listen to the community’s concerns. This engagement, she asserted, shifted the balance of power and signaled a turning point in her struggle against corporate indifference.
Roka Matbob’s engagement in politics further amplified her voice, as she became one of the few women elected to Bougainville’s House of Representatives. She described her role as not just political but deeply connected to her identity as a guardian of the land.
### The Future of Bougainville
With the Goldman Environmental Prize comes a cash reward, which Roka Matbob plans to allocate collectively with her community. “It takes a village to create a win,” she stated firmly, emphasizing the importance of communal decision-making in utilizing funds to reverse the impacts of environmental degradation.
The commitment to restoring Bougainville does not imply a return to what once was; Roka Matbob is realistic about the irreversible damage inflicted. However, she remains devoted to fostering a future in which her children and grandchildren can live in a thriving ecosystem, rather than under the pall of survival mode dictated by historical injustices.
As Roka Matbob continues her work, she embodies hope not only for her immediate community but for indigenous and environmental movements worldwide. Her story represents a powerful narrative of resilience, accountability, and the enduring spirit of those who refuse to accept the status quo.
