THE IMPACT OF CLIMATE CHANGE ON LOCAL BIODIVERSITY

ABSTRACT This study examined the impact of climate change on local biodiversity in Yobe State, Nigeria, with a specific focus on Damaturu Local Government Area. The research aimed to assess the manifestations of climate variability, its effects on plant and animal species, and the adaptive strategies adopted by local communities. A mixed method design was employed, combining quantitative and qualitative approach to capture both statistical data and community perspectives. A total of400 respondents were selected through multi-stage sampling, and data we-e collected using questionnaires, interviews, focus group discussions, field observations, and remote sensing analysis. Findings revealed that climate change has significantly altered the local ecosystem. Temperature increases of about 1.3o c and irregular rainfall pattern over the past two decades have led to severe vegetation loss, soil degradation and decline in biodiversity. Indigenous tree species such as Shea, Acacia and Baobab are rapidly disappearing, while wildlife populations have drastically reduced. The resulting ecological changes have negatively affected agriculture productivity, water availability, and traditional livelihoods. Although communities have initiated adaptation measures such as tree planting use of draught resistant crops, and water conservation these efforts remain insufficient without strong institutional support. The study concludes that climate change poses a serious threat to biodiversity and the socio-economic wellbeing of rural population in Yobe State. It recommends the strengthening of environmental policy promotion of community-based conservation programs, and investment in climate resilient agriculture. Furthermore, continuous environmental education and data-driven planning are essential to safeguard biodiversity and enhance ecosystem resilience in the face of changing climate conditions.
