World Cities Day 2026, observed from October 31 to November 2 in Fuzhou, China, brings together governments, planners and development partners to discuss inclusive urban solutions.

The United Nations says the event provides a platform for national and local authorities, UN agencies, academia and the private sector to share experiences and identify practical solutions for cities.

This year’s theme, “Regenerating the City: Adequate Housing for All,” stresses upgrading ageing infrastructure, improving informal settlements and expanding affordable housing while building climate resilience.

Kenya’s rapid urbanisation has intensified pressure on housing, sanitation, water, transport and other services, especially in informal settlements where overcrowding, insecure tenure and inadequate infrastructure are common.

A Habitat for Humanity report estimates annual demand for 250,000 housing units but notes only about 50,000 units are supplied, leaving a large shortfall.

Approximately 6.4 million urban Kenyans live in informal settlements, and around 60 percent of Nairobi’s residents are classified as slum dwellers.

UN‑Habitat and partners view urban regeneration as an opportunity to improve existing neighbourhoods while ensuring low‑income households benefit from investments in housing, infrastructure and climate‑resilient services.

The theme also calls for community‑led planning, involving existing residents in redevelopment decisions to avoid displacement and protect livelihoods.

Measures such as upgrading drainage, sanitation, roads and public spaces, alongside secure tenure and affordable housing, are highlighted as essential components of inclusive regeneration.
