The Impact of Climate Change on Biodiversity and Ecosystem Resilience in Pekalongan Regency

Climate change poses a serious threat to biodiversity and ecosystem resilience, particularly in highly vulnerable areas such as Pekalongan Regency, Central Java. This study aims to analyze the impact of climate change on biodiversity and ecosystem resilience in coastal, lowland, and hilly areas, as well as to identify adaptation strategies that have been and can be implemented. Using a qualitative descriptive approach, the study was conducted through field observations, interviews, and document reviews in several representative sub-districts. The results indicate that climate change has caused coastal erosion, shifts in planting seasons, and declines in local flora and fauna populations. On the other hand, adaptation efforts such as mangrove rehabilitation, adaptive agriculture, environmental education, and the development of ecological zoning have begun to show positive impacts, although they still face various challenges such as policy fragmentation, low climate literacy, and limited funding. This study recommends strengthening the capacity of communities and local governments, integrating cross-sectoral policies, and implementing data-based ecological monitoring as strategic steps to enhance ecological and social resilience to climate change.
