The Nairobi Declaration, adopted on 10 April 2026 at the Second Africa Urban Forum, sets a new direction for urban development across the continent. For Kenya, it is not just a continental commitment. It is a direct and urgent call to action for county governments.
Under the theme Adequate Housing for All: Advancing Socio-economic and Environmental Transformation towards the Realization of Agenda 2063, the Declaration commits countries to reducing the housing deficit by half by 2035. It also emphasises climate resilience, inclusive land use planning, and stronger local governance.
For Kenya’s 47 counties, this creates a clear implementation window. Progress will not be judged at national level alone. Counties will be the primary engines of delivery.
At Lybrae Spatial Solutions, we have translated the Nairobi Declaration into a practical, county-level spatial planning roadmap. This approach builds on Kenya’s devolved system under the Constitution 2010, as well as ongoing programmes such as KISIP II, the National Spatial Plan, and successful county experiences in Nakuru, Mombasa, Kisumu, and Kiambu.
Why Counties Must Lead Urban Planning in Kenya
Kenya’s urban population is growing at over 4 percent annually. This growth is putting increasing pressure on land use efficiency, affordable housing, infrastructure, and climate resilience.
The national Affordable Housing Programme has made visible progress, with over 262,000 housing units under construction and a target of 500,000 completions by the end of 2026. However, scaling impact depends on how well counties integrate housing with transport systems, green infrastructure, and economic development corridors.
County governments already hold constitutional responsibility for physical and land use planning. The Nairobi Declaration reinforces this role by placing implementation expectations at the subnational level.
Counties that move early to align their spatial plans with the Nairobi Declaration will be better positioned to attract investment, unlock donor funding, and build strong public private partnerships.
A Realistic View: Strengths and Limitations of the Nairobi Declaration
The Nairobi Declaration provides an important policy direction, but it is not legally binding. Its success depends on voluntary commitment by national and subnational governments.
There are several practical challenges. The monitoring framework relies heavily on voluntary reporting and a planned mid term review in 2028. There are no enforcement mechanisms or guaranteed funding streams tied to the targets. In addition, many counties face technical and institutional capacity gaps.
These limitations are not unusual for continental frameworks. However, they create a clear opportunity. Counties that adopt structured implementation approaches, strengthen planning systems, and introduce innovative financing mechanisms can position themselves as leaders in Nairobi Declaration implementation in Kenya.
A Five Step Spatial Planning Roadmap for Counties in Kenya
Lybrae Spatial Solutions proposes a five step roadmap that counties can implement within realistic timelines. The focus is on quick wins, scalable systems, and measurable outcomes.
Step 1: Rapid Diagnostic and Alignment Audit (0 to 3 Months)
Establish a data driven baseline within 6 to 8 weeks
Counties should begin with a GIS based spatial diagnostic. This includes land use mapping, population projections, climate risk overlays, and a compliance review of County Integrated Development Plans and County Spatial Plans against Nairobi Declaration priorities.
Most counties already conduct similar assessments during Annual Development Plan cycles or KISIP II preparation. With access to Ardhi Sasa data and Kenya Space Agency imagery, this step can be completed quickly and cost effectively.
Step 2: Update County Spatial Plans Using Participatory Digital Tools (3 to 12 Months)
Focus on targeted updates rather than full plan rewrites
Instead of revising entire spatial plans, counties should prioritise updates for key urban corridors and informal settlements. This includes transit oriented development, mixed use zoning, and densification strategies.
Participatory digital mapping tools and youth led data collection approaches have already been successfully applied in KISIP II across more than 30 counties. These tools accelerate planning while improving community engagement and data accuracy.
Step 3: Integrate Climate Resilience into Land Use Planning (Immediate to Ongoing)
Fast track zoning reforms within one budget cycle
Climate risk is now a central planning issue. Counties should introduce risk sensitive zoning, protect riparian areas, and embed green infrastructure standards into planning frameworks.
Recent flooding events in 2024 and 2025 have already driven policy shifts. National guidelines now require climate overlays in planning processes. Many zoning reforms can be approved and gazetted within a single county budget cycle.
Nature based solutions such as wetland restoration and urban forestry also attract climate finance and development partner support.
Step 4: Strengthen Land Value Capture and Urban Financing (6 to 15 Months)
Unlock sustainable local revenue streams
The Nairobi Declaration highlights land based financing as a key enabler. Counties can introduce mechanisms such as betterment levies, tax increment financing, and digital valuation systems in high growth areas.
There are already strong examples in Kenya. Mombasa achieved over 100 percent land rates collection in recent years, while counties such as Murang’a and Homa Bay increased revenues significantly through digitisation.
Phased pilots allow counties to build confidence, improve transparency, and reduce reliance on external funding.
Step 5: Establish County Urban Observatories (3 to 6 Months Setup)
Turn data into continuous performance tracking
Counties should establish simple but effective urban observatories using GIS dashboards. These systems track key indicators such as housing delivery, land use efficiency, and climate adaptation coverage.
Many counties already have monitoring and evaluation units. Integrating spatial data systems into these structures is both practical and cost effective. This also prepares counties for the 2028 Nairobi Declaration review and strengthens evidence based decision making.
What Timelines Look Like in Practice
Most counties in Kenya can deliver visible results within 12 to 18 months.
Leading counties such as Nairobi, Mombasa, Nakuru, Kisumu, and Kiambu can implement the full roadmap within 12 months by running steps in parallel and leveraging technical partnerships.
For other counties, early progress can be achieved within the first year by prioritising rapid diagnostics, climate zoning reforms, and urban observatories. These quick wins create momentum and build institutional capacity over time.
Overcoming Key Barriers: Capacity, Coordination, and Capital
Counties face real constraints. These include limited technical capacity, coordination challenges between national and county governments, and financing gaps.
However, these barriers are solvable. Structured partnerships, targeted capacity building, and blended financing models can accelerate implementation without compromising county autonomy.
The Nairobi National County Cooperation Agreement provides a useful framework for collaboration. At the same time, private sector partners such as Lybrae Spatial Solutions can support counties with technical expertise, implementation tools, and investment structuring.
Moving from Declaration to Delivery
The Nairobi Declaration provides direction. Counties now need practical implementation frameworks that translate commitments into results.
By adopting a structured spatial planning approach, counties can deliver affordable housing, strengthen climate resilience, create jobs, and support inclusive economic growth.
