This is the second edition of the ChangeMakers challenge—an engaging, collaborative experience uniting passionate learners and societal stakeholders to co-create solutions for real challenges in our cities and communities. Building on the first edition’s success, this new chapter offers opportunities to share perspectives and develop impactful, practical strategies for urban and community needs. This year, we welcome “Unidade de Saúde Familiar Esgueira Mais” and Veolia, whose participation enriches the experience and strengthens our collective impact. Join us in turning ideas into action.
