Advisor: Martin von Hildebrand (Colombia)

Gaia met the anthropologist Martín von Hildebrand in 1989 when he was negotiating as Colombia’s government representative, for the landmark International Convention on the Rights of Indigenous and Tribal Peoples (ILO Convention 169). In 1990 Gaia established support from the European Commission for putting the conservation of the Colombian Amazon firmly in the hands of its indigenous peoples. Martín resigned from government and set-up a local organisation, Gaia Amazonas, and together with Gaia, indigenous communities and other partners, the long term programme COAMA (Consolidation of the Amazon) was established. Today, over 25 million hectares of the Colombia’s Amazon forest is being preserved by the indigenous communities, who have taken on the rights and responsibilities of local governance. In 2015, Martin successfully persuaded the president of Colombia to lead in establishing an ‘eco-cultural corridor’ protecting up to 230 million hectares of rainforest stretching from the Andes to the Atlantic coast.

Her group methods, known as the Work That Reconnects, have been adopted and adapted to help people transform despair and apathy, in the face of overwhelming social and ecological crises, into constructive, collaborative action.

Gaia met Vandana Shiva in the mid eighties when she was fiercely defending indigenous seed varieties and farmers against the Green Revolution’s commercial seed and chemical fertilizers, which had firmly gripped Asia. Gaia worked with Vandana to bring this message to Africa, warning about the Indian experience of the destructive impact of genetically modified crops and chemical inputs. Monsanto, the largest and most aggressive private seed and agro-chemical company in the world, was at this time using South Africa as its entry point to the continent. Vandana is one of the most respected activists against GM, featuring in numerous documentaries on the subject – including Gaia’s 2012 film Seeds of Freedom and the most recent US documentary Seed: The Untold Story.

Advisor: Ailton Krenak (Brazil)

Ailton Krenak was born in the Doce River valley in the State of Minas Gerais, Brazil. A member of the Krenaki tribe, at 17-years old he learned how to read and write, became a graphic producer and journalist, and dedicated himself to the indigenous movement in Brazil. In 1987, he captured media and public attention by painting his face black while delivering a speech in the National Congress, as a gesture of mourning for the backwards steps being taken on indigenous rights. A charismatic leader, he brought together the 180 different indigenous tribes of Brazil and worked tirelessly for Indigenous Rights to become part of the country’s official constitution.

In the late 80’s Ailton Krenak and Chico Mendez united and in doing so helped overcome historical tensions between the indigenous peoples and the rubber tappers. Together they created a stronger Forest People’s Movement to stand up to the destructive forces threatening them. In 1988 Gaia launched the Forest People’s Support Group and the Forest People’s Fund, to enable them to organise their resistance and educate society about their diverse cultures and role in maintaining life in the forest. Today, the young indigenous leaders involved are leading their communities and still working closely with Ailton to advocate for indigenous rights and the protection of their ancestral lands across Latin America. Ailton remains a great inspiration to Gaia. He taught us about indigenous cosmology in the early days of our work, and was one of the first with whom we built an lifelong ‘affectionate alliance’.

Advisor: Satish Kumar (UK)

A former monk and long-term peace and environment activist, Satish is perhaps best known as the editor of Resurgence magazine, now The Ecologist & Resurgence. In his 20s he was inspired by British peace activist Bertrand Russell, and embarked on an 8,000-mile peace pilgrimage together with E.P. Menon. Carrying no money and depending on the kindness and hospitality of strangers, they walked from India to America, via Moscow, London and Paris, to deliver a humble packet of ‘peace tea’ to the then leaders of the world’s four nuclear powers. In 1973 Satish settled in the United Kingdom taking up the post of editor of Resurgence magazine. He is a regular teacher at Schumacher College in South Devon where he is still a Visiting Fellow. His autobiography, No Destination, was first published by Green Books in 1978 and he is also the author of You Are, Therefore I Am: A Declaration of Dependence and The Buddha and the Terrorist. In 2005, Satish was Sue Lawley’s guest on Radio 4’s Desert Island Discs. In 2008, as part of BBC2’s Natural World series, he presented a 50-minute documentary from Dartmoor, Earth Pilgrim, which was watched by over 3.6 million people.
