Capacity for Carbon Sequestration and Climate Change Mitigation in Different Ecologically-Distinct Zones of Sri Lanka

Sri Lanka's ecologically distinct zones (EDZs) exhibit varying carbon sequestration capacities, influenced by climate change trends such as rising temperatures and altered precipitation patterns. Using nine dynamic global vegetation models (DGVMs), researchers estimated net primary productivity (NPP), heterotrophic respiration (Rh), and net biome productivity (NBP) across eight 1°×1° grid cells from 1900 to 2009. While coarse-resolution models showed inconsistent results, finer-resolution DGVMs revealed significant spatial variation in carbon balance parameters. The study highlights the potential impact of climate change on Sri Lanka's land carbon sink capacity and underscores the importance of high-resolution modeling for accurate assessments.
