Indicator-to-impact links to help improve agricultural drought preparedness in Thailand

Abstract: Abstract. Droughts in Thailand are becoming more severe due to climate change. Developing a reliable drought monitoring and early warning system (DMEWS) is essential to strengthen a country's resilience to droughts. However, for a DMEWS to be valuable, the drought indicators provided to stakeholders must have relevance to tangible impacts on the ground. Here, we analyse drought indicator-to-impact relationships in Thailand, using a combination of correlation analysis and machine learning techniques (random for… Show more

“…The Standardized Precipitation Evaporation Index (SPEI) captures both precipitation and potential evaporation and has evolved as one of the most commonly used meteorological drought indicators in recent years (Vicente-Serrano et al 2010, Rossi et al 2023, Tanguy et al 2023. Monthly values of SPEI-1 (one-month accumulation SPEI) were provided by Zhang et al (2024) on 10 km grid resolution from 2013 to 2022.…”

Also evaluated the statistical analysis to identify the significance of spatial and temporal patterns observed in maps and created hotspot and cluster analysis through the GIS tool to show the high level of drought and WUE in different climate regions(Hoover et al, 2023;Tanguy et al, 2023).T A B L E 4 Climate zoning based on the De Martonne index.
