Urban Africa
The DPU MSc ESD/OVERDUE Learning Alliance was established in 2021/22 to support pathways towards gender equality and just sanitation across urban Africa. This translocal learning alliance brings together the DPU’s MSc Environment and Sustainable Development with partners from seven African cities: Abidjan, Ivory Coast (GEPALEF); Antananarivo, Madagascar (SiMIRALENTA/GeA); Beira, Mozambique (Austral Consultoria and FACE); Bukavu, Democratic Republic of Congo (CFCEM/GA); Freetown, Sierra Leone (SLURC and FEDURP); Mwanza, Tanzania (Ardhi University and CCI); Saint-Louis, Senegal (OGDS).

The Learning Alliance builds upon the action-research project ‘OVERDUE: Tackling the sanitation taboo across urban Africa’, which seeks to:
  1. reframe sanitation across urban Africa by unpacking the historical and colonial narratives that underpin the sanitation taboo;
  2. produce actionable knowledge based on a re-evaluation of sanitation experiences, practices and investments;
  3. take stock of ongoing experimentation towards gender equitable sanitation and foster regional dialogue and advocacy.
