Assessment of Drought Impacts on Urban Green Areas with the Climatic Drought Index in Nakhonratchasima City, Thailand

Main Article Content

Pongpun Juntakut


The study aimed to assess drought impacts on urban green areas with the climatic drought index in Nakhonratchasima City, Thailand. The Standardized Precipitation Evapotranspiration Index (SPEI) was used as the climatic drought index in this study. The study investigated and quantified the different responses of urban tree growth to drought events. The results revealed that the frequency of severe drought increased in 2017 and 2018 with the drying trend occurring in most of the study area. These results are useful for ecological assessments and planning management to mitigate the impact of drought on urban green areas. Significantly, this study is helpful to take care of urban trees growth and reduce potential damage to human health caused by air pollution e.g. PM 2.5 in urban areas.
