TerraCouncil AI is an evidence-grounded, multi-agent scientific deliberation platform developed by SustainAfrica. Complex environmental and development decisions often involve fragmented scientific data, competing priorities, and uncertainties that are difficult for decision-makers to interpret. TerraCouncil addresses this challenge by bringing Meta's Muse Spark and Muse Wonder into an interactive scientific council. The agents examine evidence, challenge assumptions, debate alternatives, and explain their reasoning through an immersive, human-like vocal dialogue. Built upon SustainAfrica's pre-existing FAITH ecosystem and FSDC scientific evidence foundation, TerraCouncil produces written scientific reports, identifies evidence gaps, and makes uncertainty explicit rather than inventing unsupported conclusions. Our hackathon demonstration explores how communities in Gaoual and Kankan, Guinea, can be better protected from flooding. The innovation creates two complementary benefits: more accessible scientific decision intelligence for users, and actionable evidence-gap feedback to help developers improve underlying data platforms. Our vision is to scale this approach across environmental protection, mining, agriculture, and sustainable development.
