Deadly floods in Kenya highlight rising climate risks, with experts warning that stronger preparedness, better infrastructure and global climate justice are essential to reduce recurring disasters across vulnerable African regions.
Dozens have died and more than 30,000 people have been displaced by torrential rains and flash floods in Kenya, reigniting debate among scientists and disaster-risk experts about climate change and the urgent need for stronger preparedness across Africa.
Since early March, heavy rainfall has battered parts of Nairobi, Nyakach and other regions, destroying homes, sweeping away crops and forcing families to flee low-lying areas. The unfolding crisis has highlighted the region’s vulnerability to recurring climate-related disasters.
The situation comes as East Africa faces alternating cycles of drought and intense rainfall, a pattern experts say is becoming more frequent.
Prof. Dewald van Niekerk, head of the African Centre for Disaster Studies at North-West University in South Africa, said scientific evidence points to climate change increasing the likelihood of extreme rainfall events across the continent.
“From a climate science perspective, it is reasonable to say that climate change is loading the dice toward heavier rainfall, more intense downpours and therefore greater flash-flood risk in Kenya and across East Africa,” he said. “The signal is not simply more rain or less rain but greater instability, more extremes and rainfall arriving in damaging bursts.”
He added that international climate assessments indicate both the frequency and intensity of heavy precipitation events are expected to rise across much of Africa as global temperatures increase.
While climate change plays a major role, van Niekerk said disasters of this scale are often driven by a combination of environmental pressures and human factors.
“The disaster outcome is co-produced by climate pressures, development choices and governance gaps,” he said, pointing to rapid urban growth, settlement in flood-prone areas and weak infrastructure as factors that turn heavy rain into humanitarian crises.
The floods have also reignited discussion around climate justice, with African countries suffering severe losses despite contributing only a small share of global greenhouse gas emissions.
“Africa contributes only a small portion of global emissions yet it experiences disproportionate losses from climate extremes,” van Niekerk said. “Countries that benefited most from carbon-intensive industrialisation carry a responsibility to support nations such as Kenya through adaptation finance, disaster support and faster emission reductions.”
He stressed that such assistance should be seen as part of global commitments under climate agreements rather than charity, including funding for early warning systems, resilient infrastructure and emergency response mechanisms.
Recurring floods in Kenya have also raised concerns about long-term disaster planning, as the same communities are affected year after year.
According to van Niekerk, governments should stop treating floods as unexpected emergencies and instead plan for them as predictable risks.
“The main lesson is that seasonal flooding should not be treated as an exceptional disaster when it is in fact a recurring risk pattern,” he said. “Governments need anticipatory risk governance that includes better land-use planning, stronger drainage systems, early warning networks and relocation plans for communities living in high-risk areas.”
He added that effective disaster management depends on sustained investment in infrastructure, social protection and environmental management rather than rebuilding after each crisis.
With heavy seasonal rains expected to continue across parts of East Africa, experts warn that without stronger climate adaptation and disaster preparedness measures, similar emergencies are likely to become more frequent, placing increasing strain on governments and humanitarian agencies.
