Drought Vulnerability Assesment of Vadakarapathy

Drought is a recurring natural hazard that significantly impacts water resources, agriculture, ecosystems, and socioeconomic stability. This study focuses on the analysis of drought characteristics using meteorological indices to evaluate temporal and spatial variations. Standardized indices such as the Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI) were applied to long-term rainfall and climatic data to assess drought intensity, duration, and frequency. The results reveal distinct seasonal and inter-annual fluctuations, with severe droughts occurring predominantly during monsoon deficits. Spatial mapping highlights vulnerable zones that are consistently prone to water stress. The findings provide valuable insights for drought monitoring and management, emphasizing the need for effective early warning systems and adaptive water resource planning. This analysis contributes to strengthening regional drought resilience and supporting sustainable development strategies.
