Short Summary

This study analyzed meteorological drought characteristics in Marathwada, India, from 1901-2021 using SPI and trend analyses, revealing a significant 49% drought occurrence, increasing drought trends, and heightened risk in southern and eastern areas, necessitating improved water management.

Objective

• To characterize the meteorological drought characteristics of the Marathwada region using the Standardized Precipitation Index (SPI) method.

Study Configuration

• Spatial Scale: Marathwada region, India (covering eight districts).
• Temporal Scale: 1901 to 2021 (121 years).

Methodology and Data

• Methods used: Standardized Precipitation Index (SPI), Kriging (spatial analysis), Mann-Kendall (MK) test (trend analysis), Spearman Rho (SR) test (trend analysis), Innovative Trend Analysis (ITA) method.
• Data sources: Historical rainfall data from eight districts.

Main Results

• The Marathwada region experienced drought conditions 49% of the time.
• Districts such as Hingoli and Nanded faced more frequent droughts than precipitation events.
• The longest drought spanned from 1918 to 1927.
• The most severe drought years included 1918, 1920, 1929, 1972, and 2015.
• Extreme drought (ED) and severe drought (SD) events occurred between 2% and 5% of the time, with mild drought (MD) and mild wet (MW) classes being dominant.
• Spatial analysis using Kriging revealed higher drought risk in the southern and eastern parts of the region.
• Trend analyses (Mann-Kendall and Spearman Rho) showed an increasing drought trend.
• Innovative Trend Analysis (ITA) indicated a significant increase in the extreme drought class.
• The spatial occurrence rates of extreme and severe droughts have increased since 2010.

Contributions

• Provides a comprehensive long-term (121 years) analysis of meteorological drought characteristics in the Marathwada region, identifying spatial and temporal patterns.
• Highlights specific districts and periods of severe drought, offering critical insights for regional water resource management.
• Identifies increasing drought trends, particularly for extreme and severe events since 2010, underscoring the urgent need for improved water resource management and climate adaptation strategies.
