An innovative initiative in Antananarivo is the PRODUIR project. It was led by the Ministry of Planning and funded externally. It is an example of a sanitation network being improved in the most vulnerable areas of the city. Small investment projects guided by micro-master plans were co-created by relevant stakeholders in the local community. This was instrumental in building knowledge, trust, and social cohesion. Utilising a multi-stakeholder approach, investing in local capacities, knowledge exchange, receiving regular feedback, and basing strategies on best practice examples were key for the PRODUIR project achieving its goals.
