Abstract

Climate change is increasingly disrupting ecosystem services that underpin human well-being, economic productivity, and global food security. Rising temperatures, altered precipitation patterns, extreme weather events, and land-use transformation collectively intensify biodiversity loss and ecosystem degradation. This study develops an integrated modelling framework to assess biodiversity loss under climate stress and to evaluate adaptive land-use strategies that enhance ecosystem resilience. Using scenario-based ecological modelling combined with land-use transition matrices, we examine the impacts of temperature increases (1.5°C–3°C) on provisioning, regulating, supporting, and cultural ecosystem services. Results indicate nonlinear declines in biodiversity richness and associated ecosystem functions under high-emission scenarios, while adaptive land-use strategies—such as agroforestry, conservation corridors, regenerative agriculture, and wetland restoration—significantly mitigate projected losses. The findings emphasize the importance of multi-scalar governance, climate-smart planning, and
ecosystem-based adaptation to preserve biodiversity and sustain ecosystem services in a rapidly warming world.
