Marathwada, Vidarbha turn hotter and drier

Mumbai: As Maharashtra reels under a drought across 265 of its 358 talukas, an analysis of 70-year weather records by India Meteorological Department (IMD), Pune, scientists revealed a deep climate divide: while Marathwada and West Vidarbha have shifted into a hotter, drier climate zone, the wettest climate zone has expanded along the coastal Konkan.
The study findings suggest that the state’s agricultural heartland is facing a double whammy - a drastically changing climate that is making the hinterland hotter and drier, which was compounded this year by the El Nino-weakened monsoon that left vast areas with rainfall deficits. El Nino effects are likely to impact even the summer monsoon in 2027.
Conducted by scientists from the IMD and the Indian Institute of Tropical Meteorology (IITM), Pune, the study has been published in the latest (October 2026) issue of MAUSAM, the IMD’s peer-reviewed journal, and incorporates data from 1951-2020.
Comparing successive 30-year periods - the standard duration used to assess climate patterns – the researchers found that Marathwada and West Vidarbha, which largely belonged to the tropical savannah zone during 1961–1990, had shifted into the hot semi-arid zone by 1991–2020.
This transition reflects an increase in daytime and night-time temperatures, placing the two drought-prone regions in a climate characterised by greater heat and low rainfall – spelling doom for the local agro-economy.
In sharp contrast, the tropical monsoon zone - India’s wettest climate belt, marked by heavy seasonal rainfall - has extended across the coastal belts of Maharashtra’s Konkan, Goa, Karnataka and Kerala.
“The spread of the wettest zone along the coast aligns with a broader pattern in the study: rainfall has increased over southern India even as it has declined over the northern plains, so Maharashtra's interior and coastline have changed in opposite directions,” said the study.
Maharashtra’s interior and coastline, however, illustrate how climate shifts can produce sharply different outcomes within the same state, said the researchers.
Significantly, the climatic changes in Marathwada and west Vidarbha are not apparent from aggregate figures for central India, where the hot semi-arid zone contracted slightly. The study’s detailed climate maps, rather than broad regional averages, reveal the transformation affecting Maharashtra’s interior.
This had immediate repercussions for a state where farming remains heavily dependent on monsoon rainfall. On Sep. 26, Maharashtra declared drought in 265 talukas after the monsoon ended 19-pc below normal. Nationally, the rainfall was 12.6-pc below normal, while Goa recorded a 34-pc shortfall and 28-pc deficit in Kerala and coastal Karnataka.
"This year's drought in Marathwada and Vidarbha is an El Niño drought, and our study does not look at individual seasons, but it does show that Marathwada and west Vidarbha now lie in a hotter, drier climate zone than they did in the 1960s, so a failed monsoon like this one lands on a climate that has itself shifted, and water and farm planning in the region has to account for that," said Ananya Karmakar of IMD Pune, the study's lead author.
“El Niño has left Maharashtra and much of the west coast well short of rain, with drought declared across most of the state's talukas. Our records show that such shocks now land on a region whose climate has been changing in two directions, with Marathwada and west Vidarbha becoming hotter and drier and the Konkan and the coast to its south becoming wetter, which is the kind of long-term change IMD needs to build into its advisories to the state's farmers," said Mrutyunjay Mohapatra, Director General of Meteorology and a co-author of the study.
The researchers stress that changing climate zones can influence crop suitability and sowing schedules, making it essential to reassess agricultural strategies rather than rely solely on historical rainfall patterns.
