Rising temperatures and more extreme precipitation have clear and direct implications for the transportation sector in Uzbekistan. Temperature rises will inevitably lead to a deterioration of the road conditions, melting of the asphalts and wear on infrastructures. Extreme precipitation will also cause greater risk for flooding and damage to roadways and bridges.

Some of the most direct impacts that climate change might have on the transport sector in Uzbekistan are listed below:

Pavement of motorways is most vulnerable to heat. Higher temperatures in Uzbekistan will require alternative types of asphalt that are more resistant to rutting and melting.  The incidence of traffic accidents strongly correlates to heat.

A shift in the seasonal precipitation and elevation is expected to increase the risk of avalanches and glacier lake breaches.

The increase in extreme precipitations events will mean that the design conditions of roadways and bridges might become inadequate. The risk of temporary or permanent disruption to transportation routes could become inevitable. Extreme precipitation is a major cause of hazards such as mudflow, flash floods and landslides, which all can disrupt infrastructure by impacting road and bridge foundation and overburdening the drainage system.


Sector Vulnerability

Hotter temperatures will affect the transport sector in Uzbekistan by causing additional asphalt rutting on roadways, especially in the southern part of the country. Greater levels of precipitation may require drainage networks and other infrastructure such as bridges to be upgraded or reinforced to be more resilient.
