They will have to find solution in greener infrastructure to restrict global mean temperature rise, it said.
Shattered rail links, fractured roads, broken power lines and ruined water wells are the “distressing facts of life” for many communities in Asia and Pacific, despite countries in the region investing higher than ever on infrastructure, ADB said in an article.
It said: “Increasingly, climate change is the culprit. Its impacts include stronger and more frequent natural disasters, like the deadly floods and landslides that recently affected Bangladesh, India, and Sri Lanka.
“Left unchecked, the toll on the region’s infrastructure will grow even higher as climate change escalates.”
Gradual impacts of natural calamities like erosion and encroaching salinity are no less “destructive” which can collapse roads and taint vital water supplies, it said.
It advocated that greener infrastructure will play a key role in restricting global mean temperature increase to less than 2 degrees above pre-industrial levels, as mandated under the 2015 Paris Agreement.
“This will require larger investments in clean energy, smart grids, better energy storage and efficiency, and where possible carbon capture and storage,” it said.
Climate proofing of infrastructure through elevation of road embankments to safeguard against flooding, relocating water intake and treatment facilities away from vulnerable areas assumes significance, according to ADB.
An improved design and maintenance of all infrastructure will have to be well taken care of, it added.
According to ADB forecast, mitigation…
