A critical lack of reliable climate data is threatening efforts to build Nairobi’s resilience against climate change, according to researchers from the Stockholm Environment Institute (SEI).

Speaking at a forum on urban planning and climate resilience in Nairobi, SEI experts stressed that poor data infrastructure is limiting the ability of planners to develop effective strategies for protecting vulnerable communities from intensifying climate threats.
“Africa’s push for climate-resilient cities is being held back by limited access to accurate climate data,” the SEI report warned.
The concern arises as African cities, including Nairobi, experience rapid urban growth—urban populations have increased from 31% in 1990 to 54% in 2020. This expansion, however, has come with challenges like growing informal settlements, rising poverty, and worsening inequality—factors that amplify the risks posed by climate change.
SEI researcher Romanus Opiyo noted that the effects of climate change—such as erratic weather and worsening air quality—are hitting African cities the hardest, yet decision-making remains constrained by data shortages.
“There’s an urgent need for climate data to guide both formal and informal planning processes and help identify urban climate hotspots,” he said.
The report identified Nairobi’s air pollution—largely caused by traffic, industry, and waste burning—as a major environmental and health issue. SEI emphasized the need for urban development strategies that align climate resilience with public health goals.
To fill the data void, SEI proposed integrated planning models and encouraged the use of community-driven approaches such as citizen science and participatory planning. Tools like the Urban ToolBox were introduced to support inclusive and informed decision-making.
Existing government programs like KISIP and KUSP were highlighted as avenues to incorporate climate priorities into urban planning—but the report cautioned that without strong data, even well-meaning policies could fall short.
“Climate resilience also enhances social equity, especially for vulnerable commuters affected by extreme weather,” the report stated.
In closing, SEI called for institutional reforms to improve coordination between urban and health planners and to ensure marginalized voices are included in planning discussions.
Experts concluded that improving data collection, monitoring, and sharing is essential. Without it, cities like Nairobi risk worsening inequality and exposing millions to escalating climate hazards.
