Brazzaville

Brazzaville has expanded through a fragmented pattern in which many peripheral neighbourhoods lack adequate roads, drainage, water and other basic services. Steep slopes and intense rainfall increase erosion and flood risk, while informal settlement in vulnerable areas makes later infrastructure upgrading more complex and expensive.

The Strengthening Urban Resilience Project targets erosion control, flood management, resilient infrastructure and public facilities in the capital, building on earlier investment in roads, drainage, water and urban planning. New municipal tools are also intended to improve asset management, drainage planning and climate-sensitive neighbourhood upgrading. This combination is important because infrastructure risk and urban growth are inseparable. Brazzaville’s long-term resilience depends on directing expansion through stronger planning while upgrading existing neighbourhoods with networks capable of handling heavier rainfall and continued population growth.
