To identify the trend of agroclimatic variabilities of eastern U. P.

Abstract

This study analyzes the annual trends of maximum temperature,minimum temperature, and rainfall across the agroclimatic zones—NEPZ,EPZ, and Vindhyan zone—of Eastern Uttar Pradesh from 2004 to 2023.Linear trend analysis indicated a consistent rise in both maximum andminimum temperatures, while rainfall exhibited a declining trend across allzones. The Mann-Kendall test was employed to determine the statisticalsignificance of these trends at the district level. Results revealed thatmaximum temperature trends were significantly increasing in Ayodhya,Mirzapur, and Sonbhadra, while minimum temperature trends weresignificant in Kushinagar and Sonbhadra. Rainfall trends showed significantincreases only in Varanasi and Sonbhadra, with other districts showing nostatistically significant changes. The findings suggest emerging climaticshifts that may impact agriculture, requiring climate-resilient strategiestailored to district-specific trends
