An increase in temperature and extreme precipitation has clear and direct impacts on the transportation sector in Turkmenistan. Rising temperatures will inevitably cause a deterioration of the road conditions, rutting of the asphalts and wear on infrastructure. More extreme precipitation will also lead to a greater risk of flooding and the risk of temporary or permanent damage to roadways and bridges.
Some of the most direct impacts that climate change might have on the transport sector in Turkmenistan are listed below:
Pavement of roads is most vulnerable to heat. Higher temperatures will require roadways to be paved with 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 roads 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 like mudflow, flash floods and landslides, which all disrupt infrastructure by putting an impact on road and bridge foundation and causing an overload of the drainage system.
The transport sector in Turkmenistan will be affected by climate change in a number of ways. Higher temperatures will lead to more asphalt rutting, especially in the western and southern part of the country where the heat will increase the most. Drainage networks and bridges may need to be re-design to strengthen resilience to heavier precipitation and heat.
