Introduction

Nestled in Kenya's ecologically sensitive Lake Victoria Basin, Homa Bay County faces complex climate challenges—including flooding, drought, and rising urban heat, exacerbated by poverty, inadequate housing and lack of public services, in particular in informal settlements.

Supported by the Global Center on Adaptation, and in partnership with Akiba Mashinani Trust and Suez Consulting, the County has pioneered Kenya's first locally led, climate-resilient development framework: the Homa Bay Municipality People's Adaptation - Local Physical and Land Use Development Plan (2025-2035).

The initial goal of developing People's Adaptation Plans for the informal settlements in the County was scaled up to develop a land use plan for the Municipality upon the request of Homa Bay's dynamic Governor Gladys Wanga. The comprehensive and integrated ten-year development Plan was developed with the strong leadership of both the County Government and its most vulnerable citizens. It was informed by highly localized data collected by the communities themselves, and through climate risk assessments and situational analyses of physical environment, demographics, infrastructure, socio-economic conditions, and governance.

The Plan will guide investments by the African Development Bank's National Urban Water Supply and Sanitation project, and, following approval by the Homa Bay County Assembly, by the County and national governments.

Homa Bay Municipality People’s Adaptation – Local Physical and Land Use Development Plan (2025 – 2035)

The Homa Bay Municipality People's Adaptation - Local Physical and Land Use Development Plan (2025-2035) addresses critical challenges including rapid urbanization, inadequate infrastructure, and rising climate risks by using extensive data collection (over 21,000 households in 13 sub-locations) and a Rapid Climate Risk Assessment. This comprehensive Plan prioritizes upgrading and tenure regularization for informal settlements and outlines a detailed land use framework, sectoral proposals, and a robust implementation and financing strategy. The Plan now awaits formal approval from the County Assembly before implementation can commence.

People's Adaptation Plans

People's Adaptation Plans were developed for the three informal settlements within Homa Bay Municipality—Makongeni, Shauri Yako, and Sofia—as part of the Homa Bay Municipality People's Adaptation - Local Physical and Land Use Development Plan (2025 - 2035).

Makongeni, a dense informal settlement situated on a hillside near Lake Victoria, was identified as the most climate vulnerable informal settlement in the Municipality. It is susceptible to flash floods, severe erosion, and landslide risks. These environmental threats are compounded by insecure land tenure and critical infrastructure deficits, resulting in annual flooding that damages services and exacerbates water insecurity. The residents of Makongeni prioritized drainage, sanitation, improved basic services, and sustainable financing to mitigate these risks.
Shauri Yako, the most central and densely populated informal settlement in Homa Bay Municipality, faces severe climate risks due to its low-lying terrain, precarious housing, and weak infrastructure. Flooding is the most persistent hazard, frequently inundating homes, contaminating water, and disrupting livelihoods. Heat stress and drought-induced water scarcity are also key threats, disproportionately affecting vulnerable groups. Priorities for Shauri Yako include improving drainage, sanitation, and water supply infrastructure, promoting resilient housing, and establishing early warning systems.
Sofia, a densely populated settlement on the shores of Lake Victoria, is home to a predominantly informal workforce, with inadequate services. Most residents rely on kiosks or wells for water, and 93.7% use pit latrines prone to overflowing during floods. Climate hazards—including droughts, heat stress, and intense flash flooding—intensify these stresses. Key interventions focus on WASH (drainage, resilient sanitation), housing (tenure regularization), infrastructure (solar power, improved roads), and livelihood diversification.

Situational Analysis Reports

Situational analysis reports were also developed for three additional informal settlements that lie within Homa Bay County, but outside of the Municipality: Remba Island, Ringiti Island and A Thousand Street.

Remba Island, a small, dense fishing settlement on Lake Victoria, faces extreme vulnerability due to unplanned growth, overcrowding, and insecure land tenure, compounded by climate change impacts. The report highlights severe infrastructure deficits: the Island is flood-prone, and over three-quarters of residents rely on untreated, polluted lake water, while poor sanitation and temporary housing heighten health risks. Remba residents called for investments in water, sanitation, renewable energy, land tenure, housing, and strengthening institutional partnerships to secure livelihoods and mitigate environmental stress.
Ringiti Island's rapidly growing informal settlement faces severe challenges including overcrowding, inadequate infrastructure, and high tenure insecurity. Residents are highly exposed to climate and market risks due to their reliance on fishing and rudimentary energy, water and sanitation services. They call for investments in tenure security, upgrading housing and essential services (water, sanitation, energy), and diversifying livelihoods through climate-resilient planning.
A Thousand Street, a highland settlement, faces severe economic vulnerability and informal land tenure that hinders investments in housing and basic infrastructure. Residents face seasonal flooding due to poor drainage, and rely on shared water and sanitation facilities. Unemployment was the key concerns of residents, who prioritized for targeted investments in drainage, sanitation, energy, and youth livelihoods, alongside addressing poverty, tenure security, and inequality.
