After two hours of practice and polish, the eight groups from the earlier Hay on Earth workshops have just three minutes to present their ideas to the specialist panel of invited experts and members of the public, who will be asked to vote and comment on the best projects. A final decision on winners will be made by the panel. The winning group receives £10,000 for their project.
AM, Minister for Environment, Sustainability and Housing will announce the four winning projects from the previous four Hay on Earth workshops.
Entry to this event is free but you must reserve a ticket.
