Majority of Lamu people depend on mangrove and fishery for trade and livelihood. However, their livelihood is now threatened by climate change which is increasingly becoming a local threat in the region. Due to destructive impacts of climate change on mangroves ecosystem, most of mangrove traders and fisherfolk in Lamu Kenya have seen their source of livelihood shrinking day by day. The study examined the impact of climate change on mangrove -dependent livelihoods in Lamu county through a climate justice lens. The study was based in Lamu County that is one of the six coastal counties in Kenya. The study adopted quantitative and qualitative research approach. For quantitative approach, descriptive survey research design was adopted with data being collected using data collection sheet and house hold survey. The climate variables of concern included mean sea level, rainfall, and temperatures. Qualitative approach adopted focus group discussion and key informant interview to collect needed data. Data was analysed using SPSS and Microsoft excel. The descriptive statistics used in the study included mean, minimum, maximum and graphs. Inferential statistics adopted included regression, Paired t test and Mann-Kendall non-parametric test. Qualitative data was transcribed and analysed using content analysis technique. The analysis involved identifying themes developed from research questions and narrative responses from the respondents in the FGD and KII. The erratic climate conditions experienced in Lamu have impacted on mangroves and mangrove dependent livelihood via destruction of properties and infrastructure, reduced availability of mangrove products, destruction of recreational sites and beaches, fresh drinking water problems, the emergence of livestock and animal diseases among others. The study suggests increased funds allocation to programs aimed achieving climate justice. The study contributes to body of knowledge on the nexus between climate change and ecosystem dependent livelihoods. The study reveals how temperature, rainfall and sea level variability is impacting mangrove dependent livelihoods.
