The ASEAN region is grappling with the harsh realities of climate change. From rising temperatures and fluctuating rainfall to escalating sea levels and increasingly severe weather events—droughts, storms, floods, typhoons, and heatwaves—the impacts are profound and far-reaching. These climatic shifts have wreaked havoc on human life and infrastructure, worsened water shortages, disrupted agricultural productivity, and posed severe threats to food security. Additionally, climate change has intensified forest and peatland fires, caused transboundary smoke haze, led to land degradation, soil erosion, and damaged coastal and marine resources. The increased risk of infectious diseases further exacerbates these challenges.
