Potential impacts of altering heavy precipitation events on crop production in Dong Thap province over three past decades
Year: 2024
Type: article
Abstract: This study assesses heavy precipitation trends for in Dong Thap province of Vietnam based on daily precipitation data applying the Mann-Kendall test and Sen’s slope estimate, in order to detect the change trends in the period 1985-2021. The results of the analysis show that the number of heavy precipitation events (20 ≤ R < 50) at Cao Lanh and Hong Ngu stations is relatively high, with an average of 18.7 and 15.7 days per year while the number of precipitation events from 50 ≤ R ≤ 100 mm is relatively low, with an average of 3.5 and 2.9 days per year. However, the extreme precipitation intensity (Rmax) has recorded 82.1 and 73.1 mm and detected an increasing trend in Cao Lanh station and decreasing in Hong Ngu station. The result indicates a change in the characteristics of heavy precipitation in Dong Thap province over the past three decades. The findings will provide valuable insights into the impacts of heavy precipitation events on crop production in the region and will support policymakers and farmers to develop solutions to mitigate the effects of these events.
