Speaking at the opening of the Architectural Association of Kenya (AAK) Annual Convention in Kisumu, Rossbach said both developed and developing nations are facing acute housing challenges, from affordability crises in the North to widespread informality in the South.

“Young people cannot afford to rent or buy homes, migrants struggle to settle, and millions live in informal settlements,” she said.

She added, “We are also witnessing homes lost to conflict, floods, fires, and rising seas. The most vulnerable always pay the highest price.”

Rossbach highlighted UN-Habitat’s new 2026–2029 strategic plan, which prioritises housing, resilience, and climate-smart cities. She stressed that solutions must be driven by local governments and communities.

“Housing is not just about shelter; it’s about dignity, prosperity, and resilience. Cities account for 70% of global emissions and 60% of energy consumption. We cannot address climate change without addressing how our cities are planned and built,” she noted.

Kisumu Governor Anyang’ Nyong’o used the platform to rally architects and planners to partner in implementing the city’s ambitious New Kisumu City Master Plan.

He described it as a blueprint for transformation, anchored on lakefront revitalization, modern transport infrastructure, and dignified upgrading of informal settlements.

“For too long, Kisumu turned its back on the lake. My legacy will be to turn our city around to face it,” Nyong’o said.

The governor added, “We are committed to ensuring development uplifts communities rather than displacing them. A rising tide must lift all boats, not wash them away.”

AAK President Architect George Arabbu underscored the role of professionals in driving sustainable urban growth, cautioning against unregulated construction.

“According to the National Building Inspectorate, up to 80% of our buildings are irregular. We cannot meet our decarbonisation goals if we bypass professionals,” he said.

The convention, themed “Shaping the Urban Future Towards Sustainable, Equitable, Resilient and Smart Cities for All”, brought together architects, planners, policymakers, and development partners.

Delegates are expected to deliberate on innovative approaches to social housing, climate action, and urban financing. Rossbach also called for stronger coalitions.

“No single entity can solve this challenge alone. Partnerships, co-creation, and local leadership are key to building the sustainable cities Africa needs.”
