For low-income families, health and adequate housing can feel like an impossible tradeoff. Many are incremental builders—shut out of formal housing markets and unable to afford high‑quality materials or certified labor—who construct their homes slowly, with whatever resources are available. In places like Kenya, high material costs and long‑standing building practices mean that many homes, particularly in rural areas, have grass‑thatched roofs, unsealed eaves, poorly sized or unscreened windows, ill‑fitting doors, and insufficient mosquito screening. It creates ideal entry points for mosquitoes that spread malaria. Bakari’s home was no exception.

Yet even small improvements can make a difference.

In sub‑Saharan Africa, Habitat’s healthy housing programming includes malaria prevention and water, sanitation, and hygiene interventions. Replacing dirt floors with concrete reduces parasitic infections. Repairing leaky roofs eliminates mold. Installing screens keeps disease‑carrying insects out. Even simple home upgrades can dramatically reduce vulnerability to malaria and other illnesses.

“We want malaria to become a top‑of‑mind issue for everyone involved in the housing sector—not just for public health actors,” says Roland Pearson, vice president at Habitat for Humanity’s Terwilliger Center for Innovation in Shelter. “When we frame malaria as a challenge that can be addressed through smart, cost‑effective housing improvements, we can encourage the entire housing value chain to incorporate targeted solutions into their products and services. That’s how malaria prevention becomes mainstream, and how homes become safer for families across all income levels.”

Innovations that close the door to malaria

To strengthen the links between health and malaria free homes, Habitat’s Terwilliger Center for Innovation in Shelter is helping drive scientific, community‑informed, and market‑ready solutions that reduce mosquito entry into homes.

In 2021, the Terwilliger Center partnered with SeaFreight Labs to launch an open‑innovation challenge seeking practical and affordable ways to modify existing homes and reduce malaria transmission in Kenya. Among 78 submissions, the winning concept, “Mosquito Free Homes: Air Cavities and Screens,” proposed a simple and affordable modification which included the installation of air cavities for improved ventilation and lighting while blocking mosquito entry, combined with striped nets and Velcro‑based screens for windows, doors, and eaves.

The solution caught the attention of local stakeholders. When tested at the Kenya Medical Research Institute in Kisumu, this solution reduced indoor mosquitoes by an astonishing 89%.

Though initial field pilots in rural communities raised concerns about aesthetics, privacy, and cold temperatures during cold months, the innovation generated valuable insights that continue to shape new prototypes and community‑driven refinements.

Habitat’s collaboration with KEMRI deepened in 2022, leading to a landmark peer-reviewed, field study published in Nature Medicine in early 2026. The study evaluated low‑cost modifications—including cool roofs, cross‑ventilation, papyrus‑mat ceilings, and mosquito screening—across rural homes in western Kenya. And the results were clear:

• Screens reduced the number of malaria‑carrying mosquitoes indoors by 77%.
• Cool roofs significantly lowered indoor temperatures by up to 3.3°C, helping households withstand extreme heat.
• 85% of participating families expressed their willingness to invest their own resources in similar upgrades.

In addition to the immediate health and wellbeing benefits of these interventions, the interest of families to invest in these homes is crucial. It signals real potential for long‑term, market‑driven adoption of healthier housing designs.

“Collaborating with Habitat for Humanity has strengthened our ability to test housing‑related malaria interventions in real‑world settings,” Dr. Bernard Abong’o, lead researcher at KEMRI’s Centre for Global Health Research. “KEMRI brings the research, and Habitat contributes practical insights into how housing improvements are adopted, built, and financed by low‑income households. This combination helps ensure solutions are evaluated not only for their technical performance, but also for their affordability and suitability for the communities that are most affected.”

Mzee Bakari has seen firsthand how these simple home modifications have improved life for his family. Sealed gaps and screened openings now keep mosquitoes out, and a reflective paint coating on the corrugated iron roof has reduced indoor heat and even helped soften the sound of rain. “Nowadays we sleep peacefully,” he says. “We do not experience mosquitoes in the house.”

In Kwale County, Agnes’ family bore the constant toll of mosquitoes and oppressive heat. Malaria was a regular and exhausting presence in their home. “Every few weeks, one of my children would come down with malaria,” she recalled. After several months of community sensitization, Agnes partnered with KEMRI to implement improvements based on the study’s findings. The impact was felt almost immediately. “The house is now cool, and the number of mosquitoes has reduced. We can sit comfortably indoors, and we haven’t had a case of malaria recently,” she said.

For families, these benefits extend far beyond mosquito reduction. Cooler homes improve thermal comfort and reduce heat‑related illness, while better ventilation improves air quality. Well-placed screens on windows and doors protect against a range of disease‑carrying insects—not only the malaria-transmitting Anopheles mosquito but also flies that spread other diseases.

Looking ahead

Despite promising advances, the work is far from over. In 2025, Habitat and SeaFreight Labs launched a second innovation challenge, “Reducing Malaria Spread with Improved Air Quality Ventilation,” to refine and optimize air cavity designs. As of March 2026, five promising concepts are undergoing community review before being tested in the community.

Meanwhile, the Terwilliger Center and KEMRI are advancing a new cluster randomized trial involving 300 households. This research will test scalable combinations of cooling and mosquito‑control solutions to identify the most` effective, affordable models for low‑income families. The goal is to ensure these innovations work not just in laboratories, but in real homes, built by local masons, purchased by families, and sustained by markets.

The changes have also drawn interest from Bakari’s neighbors, many of whom are now curious about making similar improvements to their own homes. “Because of what I have seen and felt,” he says, “it is easy for me to convince others to try these modifications.”

Agnes is eager for others to benefit too, “Our lives are different. I would encourage my neighbors and anyone else to try out these interventions,” she concluded.

In Africa and around the world, Habitat works with communities to create homes designed not only for stability, but also for health. A decent, affordable and healthy home—one that keeps mosquitoes out, stays cool in rising temperatures, and supports the physical and mental well‑being of its occupants—is one of the most powerful tools against climate‑and disease‑related risks.

On World Malaria Day, we honor the families, researchers, local builders, and community partners who are working together to create a world where home is a place of health.

Because when we build healthier homes, we build healthier futures.

Among them was Christina, a single mother caring for four children. After the storm washed away her home, Christina and her family were relocated to the Namchidwa camp, where they lived in a temporary tent alongside hundreds of other displaced families. With no stable shelter and no source of income, the future felt uncertain.

Recovery began when Christina partnered with Habitat for Humanity Malawi, local leaders and the district council to rebuild a safe and permanent home for her family. What started as support for one community soon grew into something bigger. With funding from the Gale family, 17 permanent homes were constructed in Namchidwa village. That initial effort inspired additional partners to step forward, making it possible to build 37 more homes.

Recovery efforts also focused on long-term resilience with 17 young people receiving vocational training, and over 1,000 community members participating in sessions on safe shelter practices. 

Today, Christina and her children are rebuilding their lives in a safe place they can call home. Across the community, recovery work is still underway as families continue to rebuild their lives and look toward a more secure future.

Their story is a reminder that recovery after disaster often begins with a home – opening the door to resilience for families and communities alike.

A documentary capturing the experiences of families in Namchidwa was produced with support from the Gale family, sharing the voices and resilience of those rebuilding after the storm.

Encouraged by the campaign, she reinitiated her appeal process. In September 2025, after 31 years of persistence, Emebet finally received the title deed to her home.

“Now I feel like a homeowner. I sleep well and can focus on building my future,” she said.

Today, she gives back to her community by partnering with Habitat Ethiopia through the campaign to train other women facing similar challenges.

For Emebet, the document represents more than legal recognition. It represents peace of mind, dignity and the freedom to focus on her livelihood and future.

Ketty builds a future through skilled work – Uganda

In Uganda, Ketty is building her future through skilled work.

Today she works as a skilled welder, producing metal products and earning a steady income that allows her to support herself and plan for the future. The journey to this moment required determination and the opportunity to learn a new trade after financial challenges forced her to leave school.

Through a collaboration between Habitat for Humanity Uganda and the Citi Foundation under the Global Innovation Challenge, Ketty received vocational training in welding — one of several construction and technical trades where young people are gaining practical, marketable skills that contribute to building and improving homes and communities.

Ketty is the only female trainee among 150 youth gaining hands-on experience in fields such as welding, carpentry, construction, electrical installation and plumbing. The program is helping young people transition into sustainable livelihoods while contributing to stronger, more resilient communities.

In a field where women are still underrepresented, she is proving that skilled trades are not limited by gender. For Ketty, the training has opened the door to independence and dignity.

“Now I can earn my own income and take care of my needs,” she says.

Her supervisor notes her commitment and skill in the workshop, describing her as a talented craftsperson who produces high-quality work and continues to grow in confidence.

Protecting livelihoods and coastlines – Ghana 

In the coastal community of Woe in Ghana’s Anloga District, Madam Comfort is helping restore the mangrove ecosystems that protect local livelihoods and shorelines.

A vegetable farmer, fishmonger and mother of four, Comfort has witnessed firsthand the effects of climate change. Rising sea levels, coastal erosion and flooding have damaged crops and threatened incomes for families who depend on the land and sea.

Comfort volunteers in mangrove restoration through the Improved Resilience of Coastal Communities – Adaptation Fund project, a regional initiative co-implemented with UN-Habitat, ActionAid Ghana, the University of Twente, the Abidjan Convention, and national governments. The efforts are designed to strengthen natural coastal defenses and safeguard community livelihoods.

Over the past weeks, she has joined other volunteers in planting mangroves along vulnerable sections of the coastline. 

Mangrove ecosystems are a lifeline for coastal communities, reducing erosion, absorbing floodwaters and protecting shorelines from storms while supporting livelihoods such as fishing.

For Comfort, resilience begins with collective action. By restoring mangroves, she and her community are helping safeguard their homes, livelihoods. 

“I feel happy knowing that, in my own small way, I am contributing to a cause that will positively impact my generation and generations yet unborn,” she says.

Joyce’s dream of homeownership – Kenya

In Nanyuki, Laikipia County, Joyce and her family recently celebrated a milestone she once thought impossible: becoming homeowners.

Joyce lives with her two daughters and grandchildren and supports her family through casual jobs in the community. For years, stable housing felt out of reach.

In January 2026, volunteers from Habitat for Humanity Kenya and Habitat for Humanity Greater Rochester partnered with Joyce’s family to begin construction of a safe, decent home.

Joyce laid the first brick herself as the foundation took shape. Over the following days, volunteers and family members worked side by side mixing mortar, carrying materials and raising the walls of the new home.

“I never thought this day would come,” Joyce said. “Now I am a homeowner, and my family has a safe place to live.”

For Joyce, the house represents stability, security and a new chapter for her family.

Building foundations for opportunity

The stories of Emebet, Ketty, Comfort and Joyce show how access to housing and land can open doors to opportunity.

When women have a safe place to call home, they gain the stability needed to pursue livelihoods, support their families and contribute to their communities.

As we join the world in celebrating the strength, resilience, and leadership of women, it is imperative that safe and affordable housing is recognized and prioritized as a foundational investment in well-being and gender equality.
