Major infrastructure and energy projects linking Central Asia and South Asia — including pipelines, road corridors, and power transmission lines — were designed under climatic assumptions that are rapidly becoming outdated, experts warn. Shifting weather patterns, glacial retreat, and increased flooding across the Himalayan and Hindu Kush regions now threaten the physical viability and long-term returns of these investments. The mismatch between original project planning and current climate realities raises urgent questions about how governments and financiers will adapt cross-regional connectivity strategies that many countries depend on for economic integration.
