Antananarivo

Antananarivo combines a historic hill city with a much larger metropolitan area spreading across low plains and surrounding municipalities. This topography creates a sharp contrast between dense hillside neighbourhoods and flood-prone lower districts, while the convergence of national roads in the capital contributes to severe congestion.

Current investment addresses both vulnerabilities. PRODUIRE2 expands flood protection, drainage, solid-waste management, neighbourhood upgrading and land administration across Greater Antananarivo. A separate 2026 multimodal transport programme will rehabilitate the railway toward Toamasina and develop a rail-road dry port and logistics platform near the capital, intended to improve freight movement and reduce pressure on the port corridor. These projects treat metropolitan resilience and mobility as linked problems: the city needs safer low-lying neighbourhoods as well as infrastructure capable of moving people and goods through a constrained urban system.
