Paradigm Initiative in partnership with Tanzania Community Networks Polytechnic College hosted the 4th Tanzania School of Community Networks on May 27, 2025, which convened stakeholders in the Community Networks (CNs) ecosystem in Tanzania to build their capacity in running sustainable community networks, examine barriers to running sustainable Community Networks, and propose actionable policy, legal, and strategic recommendations towards addressing those barriers. The event was conducted with the aim of contributing meaningfully to the closing of the digital divide in Tanzania. This policy brief, an outcome of a stakeholder consultative session held during the school, outlines the challenges CNs face, the gaps in digital infrastructure and internet use and makes targeted recommendations to promote legal recognition, sustainable financing, and inclusive digital infrastructure for CNs and underserved communities in Tanzania.
