Katalis Kalimantan 2025 is a Training of Trainers (ToT) programme co-organised by AktivAsia and partner organisations across Kalimantan. Held from 6–10 October 2025 at Ecovillage, Palangka Raya, Central Kalimantan, the training builds facilitation capacity among 15 emerging trainers from environmental NGOs, worker unions, and youth organisations across Kalimantan. Participants are drawn from BHI alumni, Kaltara youth networks, KSN unions, WALHI chapters, and Swarapena, equipping them to design and deliver high-quality training in their own organisations and communities.
