A facilitator's guide: Dreamtown has co-designed inspiring educational material that reflects the challenges, priorities and approaches that are important for sustainable development in urban communities. Through the SDG Challenge, we aim to establish a space for the voice of young activists to come forth and shape the communication and framing of development contexts - and learn about developing ideas and projects as solution to urban challenges. This handbook is designed to assist Dreamtown in facilitating an educational programme for young people. The Handbook provides information and tools required to conduct the case challenge by Dreamtown and potentially other NGOs interested.
