The Nyeri County Climate Change Action Plan (CCAP) 2023-2027 is a five-year plan to steer climate change action in Nyeri County. The Plan derives from the Kenya Climate Change Act (No.11 of 2016) and the Climate change (amendment act) No. 9 of 2023, which requires county governments to develop Climate Action Plans to guide the mainstreaming of climate change into their functions and development. Further, the Nyeri County Climate Change Act 2021 (Sections 25 and 26) provides for partici- patory climate action Planning. The Nyeri CCAP 2023-2027 will ensure the achievement of Nyeri County development goals by providing mechanisms to realize low carbon climate and resilient development pathways. The plan emphasizes sustainability while prioritizing adaptation and enhanced climate resilience for vulnerable groups, including women, youth, persons with disabilities, and marginalized and minority communities. This plan has been developed at a time when significant changes in the local climate were evidenced and documented in the Nyeri County Participatory Climate Risk Assessment Report, 2023. Climate-related disasters, particularly landslides, droughts, frost, floods, pests and diseases, were frequent, and their impacts adversely affected the economy and livelihoods in the county with the frequency of cold days and nights, having increased temperature rise spanning across all seasons and rainfall patterns changing.
