Everyday thousands of refugees cross international borders, fleeing from war, violence and uncertainty. In Brazil, at least 100,000 new refugees have arrived since 2017, many from Venezuela. A major challenge is accessing basic services. To meet this challenge, Igarapé Institute launched OKA, a free mobile app. It connects new arrivals – refugees, asylum seekers and also internal displaced and vulnerable communities with critical geo-located information on shelter, food sources, education, transportation and health services.
