How Do You Wash Your Hands When the Jerrycan Is Empty?
What 603 households in Turkana taught us about climate adaptation that starts with behaviour, not hardware
How do you wash your hands when the jerrycan is empty? That's the daily reality for a household living through drought.
The SCORE II project has been at the forefront of constructing boreholes, laying water pipelines and setting up water committees across communities in Turkana County. That infrastructure work is critical. But it doesn't explain why two households drawing from the very same water point can end up with entirely different health outcomes. The difference sits in behaviour, and behaviour is where climate adaptation either takes root or quietly fails.
That was the premise behind Tuwajibike, the Social and Behaviour Change (SBC) campaign CBCC designed and delivered as the SBC component of the UNICEF-led SCORE II project, funded by KOICA and implemented in partnership with the County Government of Turkana and other partners. Tuwajibike means “let us take responsibility.” We chose it deliberately. In much of Turkana, climate shocks are received as fate, floods and droughts as things that simply happen to you. The campaign's entire theory of change rested on a single reframing: communities cannot control the rain, but they can control the response.
Four pillars, three channels
We built the campaign around four pillars, each one a behaviour cluster rather than a topic:
Tujali (We Care) — hygiene and water safety that hold up when water is scarce
Tujiandae (We Prepare) — latrines that survive floods, livestock decisions made before the drought bites
Tujulishane (We Inform) — weather alerts moving between youth with phones and elders with knowledge
Tulindane (We Protect) — water infrastructure defended, tariffs paid, girls kept in school when crisis tempts families toward early marriage
These moved through three channels simultaneously: community health promoters (CHPs) conducting several rounds of household visits across Turkana Central; school health clubs reaching learners across Turkana Central, Loima and Turkana South; and Makala ya Tumaini, a weekly radio magazine programme on Ejok Radio.
What actually changed
Across households, schools and radio audiences, understanding of climate-resilient WASH practices deepened well beyond expectations, and everyday habits followed suit: safer water storage, reinforced latrines and functional handwashing stations became the norm. Households didn't just adopt these practices, they taught their neighbours, spreading ownership through the community, despite some setbacks.
It worked through accountability, not clever messaging. Households made specific, time-bound commitments to a named community health promoter who returned to check on them. Completion rates climbed steadily, and lagging areas caught up once support was redirected. The barrier was never willpower; it was simply a reason to act now.
Most households still name water scarcity as their biggest challenge, and most said the cost of materials, not lack of skill, would stop them keeping their final commitment. When knowledge is removed as a barrier, it exposes the resource constraint beneath it, turning a diffuse problem into a specific, fundable one.
Lessons learned
The Tuwajibike campaign ran for a matter of months, not years. Conventional wisdom says behaviour change needs longer. Our experience suggests something more interesting: a short campaign with a tight accountability loop can outperform a long one with a diffuse message. Three lessons are worth carrying into the next programme:
Make the commitment specific and name the person who will check. Vague encouragement produces vague results.
Translate the frame into the local moral vocabulary. Tuwajibike worked because responsibility is already a value in Turkana we didn't import a concept; we pointed at one already there.
Measure reasoning, not recall. Asking “what do you do?” gets you social desirability. Asking “what is the correct way, and why?” gets you the truth.
A fourth lesson sits alongside these: knowledge and motivation can be built quickly, but they will always run into the limits of what a household can afford. Behaviour-change programming that succeeds on its own terms should expect to surface a resourcing gap and treat that as a sign of progress, not a shortfall.
Moving forward
People's readiness in Turkana Central is still growing. What the community is asking for and has clearly earned is the hardware and resources to keep up with it.
If you work in WASH, climate adaptation or social and behaviour change in arid and semi-arid lands, we'd welcome your perspective: what has (or hasn't) worked to close the gap between knowing and doing in your own programming? Drop a comment or get in touch we're keen to compare notes.
With thanks to UNICEF, KOICA, the County Government of Turkana, our community health promoters and every household in Turkana Central who made this campaign theirs.
