Nairobi Opens Climate Summit With Street Art and Housing Hope

Artists took over Nairobi's streets this week, painting vibrant murals about climate action before the city's biggest international summit began. The street art wasn't just decoration—it was an invitation for everyday residents to join global leaders in reimagining what cities can become.

The 2026 Innovate4Cities Conference opened at the UN Complex in Gigiri, marking the first time this major climate event has been hosted in Africa. Housing and community-led planning took center stage as delegates tackled a reality millions face: how to build climate-resilient cities while populations grow rapidly.

UN-Habitat's Anaclaudia Rossbach challenged a common misconception during the housing plenary. Informal settlements aren't simply unplanned chaos—they're evidence of planning systems that fail to provide affordable housing for low and middle-income families.

Rossbach connected the dots between inadequate planning and recurring disasters. The floods, fires, and droughts hitting cities like Nairobi stem from development models that ignore land's social and ecological purposes, she explained.

Climate scientist Debra Roberts pushed for concrete investment in nature-based solutions and settlement upgrading programs. These aren't just nice ideas—they're essential protection for vulnerable communities facing long-term climate risks.

Costa Rica's ambassador Veronica Garcia emphasized something revolutionary: residents must be co-creators and decision-makers in urban planning, not afterthoughts. Local knowledge should guide development from day one.

The discussions carry urgent weight in Nairobi, where 60% of residents live in informal settlements facing flooding, extreme heat, and poor drainage. These aren't abstract policy problems—they're daily realities for millions of families.

The Ripple Effect

What happens in Nairobi could transform cities across Africa and beyond. Community-led upgrading of informal settlements, backed by climate financing and scientific planning, offers a proven pathway to resilience that other rapidly growing cities can follow.

Nairobi County's Housing Executive Maureen Njeri issued a challenge to close the session. The solutions discussed must move beyond research and scale into real projects that strengthen the city's resilience and can be replicated continent-wide.

Delegates agreed the summit's success won't be measured by speeches alone, but by how quickly housing and upgrading projects reach the neighborhoods that need them most.
