"Oh my God, what is going on today!" —
exclaimed a little girl, peering down at us as we climbed the last leg to the rooftop, eight floors up, into a little crowd of children playing and chatting away, the rooftop view — another block.
The ascent through the blocks, despite the blinding sunlight outside, led us through dark 'by-passes' — spaces that transform into income-generating shortcuts past 10pm with small stores and salons carved into the walls, pitch black staircase cores of uneven risers, where the location of the step felt uncertain, and corridors with each flight to the top letting one extra shade of distant light, fighting its way to the ground.
Outside each home, stacks of three to five levels of jerry cans lined the walls, further narrowing the passageways, a quiet but urgent signal of irregular access to water.
Children raced up and down the passages, eyes perhaps now adapted to the darkness, navigating a floor print of roughly 28m x 8m with floor to floor heights at staircase landings no more than 2.2m, spaces where the body adjusts as much as the eye.
Women washed clothes in basins along the corridors drawing back water on the floor that flowed beyond an invisible boundary known only to the inhabitants. Lightwells, though present, did little beyond present a need of steel balustrades, strung from one end to the other with lines of drying laundry, already full.
Stepping outside, blocks stretched into continuous vertical walls featuring multiple façade treatments, animated by balconies that introduced a rhythm — dynamic, yet repetitive. Laundry remained the most vivid expression of the lives within: colourful layers of clothing stretched across buildings, often in multiple tiers, revealing density and occupation. The manner in which clothes were hung revealed ingenuity where trousers pegged at the hems allowed for the heaviest part (the waist) to hang downward, using gravity to drain water faster.
Despite clear skies, translucent plastic sheets covered parts of the hanging laundry. On the road below — at times muddy, strewn with rubbish, and barely passable — the reason became evident: water dripping from freshly washed clothes fell onto pedestrians and onto the layers of laundry extending from the floors below.

The risks are undeniable, but so are the adaptations.
What emerges here is not just density, but a spatial system shaped by scarcity, yet one where sometimes the risks cannot be left to adaptation alone.
Urban risk in informal settlements is increasingly systemic, interconnected, and health-driven, requiring integrated and community-centered responses.
Health outcomes, particularly non-communicable diseases (respiratory illnesses, mental health) highlight deeper structural challenges linked to poor waste management, inadequate drainage, and environmental exposure. These should be understood as indicators of systemic vulnerability, not isolated issues.
Risks are mutually reinforcing, with infrastructure, environmental, and social factors compounding impacts (e.g. drainage failures leading to flooding and disease outbreaks, or illegal electricity connections increasing fire risk). This underscores the need for multi-sectoral approaches to urban resilience.
Strengthening community cohesion emerged as critical, including:
Targeted stakeholder engagement
Youth empowerment
Addressing GBV and security concerns
Supporting community leadership and champions
Resilience is therefore both a technical and social process.
There is also a clear need to strengthen governance linkages, including:
Improved community understanding of government systems
Stronger connections to decision-making processes
Support to policy review and feedback mechanisms
Organizations such as Kounkuey Design Initiative play a key role in bridging community knowledge and policy frameworks.
Key takeaway:
Addressing systemic urban risk requires a shift from reactive responses to anticipatory, integrated, and equity-centered resilience approaches, grounded in community knowledge and practice.
As we were going around, I noticed how people seem to have normalized living with risk.

The citizen scientists talked about their experience as resident experts.
It was an overwhelming and traumatising experience, explained both Claire Momanyi and Martin Onyango.
“I felt vulnerable and exposed. It was like being in the middle of chaos,” said Martin.
It was, however, an opportunity for them to view risk from a systemic lens and denormalise the dominant view of response to risk. From their observations, Pipeline and Saika have many similarities and slight differences, which simulate the future of urban settlements.

James Thiaine from Kenya Power and Lighting Company raised a concern about safe power supply and connection due to the prevalent cases of electrocution in dense settlements.
Prevalence of non-communicable diseases was also raised by Juliet Ayieta from the Kenya Red Cross. A resident wanted to know the timeline for them to see tangible action in response to the risks experienced by the residents of Pipeline.
These risks stem from a lack of and little implementation of laws, policies, guidelines and regulations. This is worsened by the passive nature of citizens in governance processes. A few people make decisions that affect the majority who happen to be vulnerable to risk. The vulnerable people should be at the decision-making table with an informed awareness of risk.
Despite the challenges faced by residents in these settlements, they have come up with ways to cope with the risks they live with. Mutual aid is seen in the way communities come together to fundraise for floodlights and form community security teams to address insecurity. Waste pickers reusing, recycling and repurposing waste collected from households and community groups are reclaiming spaces within the neighbourhoods and along the railway and river into recreational spaces. These are community-led adaptations that need support to scale and to inform urban planning and design based on the needs of the residents.
George Arrabu of the Architectural Association of Kenya (AAK) said "Pipeline is a simulation of the future" and Martin Onyango also said he sees Saika becoming like Pipeline in the near future.
Both settlements experience the same challenges: deficient infrastructure for utilities and services that manifest in forms such as leaning and overloaded power lines, poor waste management practices and water shortage.
Saika has vertically dense buildings, while Pipeline has buildings that are both vertically and horizontally dense. The escalation of risk is therefore faster in Pipeline, given the density of the buildings and the population, which is higher than in Saika.

The conversation culminated with the Director of Disaster and Risk Management talking about the pilot community emergency response teams yet to be trained and deployed in all 17 sub-counties and 85 wards as first responders to incidents occurring in dense settlements such as Pipeline. The recruitment of these teams will be done through the National Government Administrative Officers.
The Director also talked about the multilevel and multistakeholder engagement being convened by the National Disaster Operation Centre to ensure coordinated collective disaster preparedness and response by government and non-governmental agencies. These interventions provide an opportunity to work with citizen scientists to pilot practical steps on how residents and county government engage in response to risk. They are also a platform to explore the role of citizen science in understanding how systemic risks compound and cascade.
The discussants call to action was for citizens to become more active in policy and intervention processes. Regina Opondo of KDI proposed practice, policy and community action, including:
Embedding citizen science into everyday community organizing so that communities use data and their voice as power.
Pushing for systemic risk to be a policy priority and an election agenda in the manifesto.
Mobilize residents to use their voice to shape policies and interventions.
Juilet Ayieta of the Kenya Red Cross called on residents to engage in the existing processes of disaster preparedness and response through organizing themselves for trainings on first and other emergency response trainings done by the county department and Red Cross. She also emphasized the critical role of active citizenry in ensuring public safety in settlements by reducing vulnerability to disasters and informing better disaster response and preparedness through policy review to address the implementation and enforcement gaps.
