Research on the effects of temperature due to climate change on coastal roads in Kien Giang province

Abstract

Climate change and sea level rise have been happening globally. Humanity has had to deal with many consequences from extreme weather phenomena that appear more frequently and with greater intensity. Many studies show that Vietnam is one of the three countries heavily affected by climate change, suffering losses equivalent to (6÷7)% of GDP each year. Kien Giang province is located at the tip of the country, with more than 200 km of coastline, the system of road works in the coastal area in the province annually suffers hundreds of billions of VND in damage due to the impact of adverse extreme weather phenomena. This article presents a study on determining a set of risk assessment indicators, the vulnerability of coastal road works during operation due to the impact of climate change, focusing on the type of hazard: Road surface damage due to increased frequency of extreme temperatures. This result shows the picture of the risk level and vulnerability of the route according to each spatial unit and provides the units managing, operating, exploiting and maintaining the road with a picture of the risk level and vulnerability, recommendations to enhance the resilience of the construction to the hazards related to extreme temperature changes during the exploitation management process

Keywords: Road vulnerability; risk; climate change; coastal road; extreme weather.
