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 and
minimum temperatures, while rainfall exhibited a declining trend across all
zones. The Mann-Kendall test was employed to determine the statistical
significance of these trends at the district level. Results revealed that
maximum temperature trends were significantly increasing in Ayodhya,
Mirzapur, and Sonbhadra, while minimum temperature trends were
significant in Kushinagar and Sonbhadra. Rainfall trends showed significant
increases only in Varanasi and Sonbhadra, with other districts showing no
statistically significant changes. The findings suggest emerging climatic
shifts that may impact agriculture, requiring climate-resilient strategies
tailored to district-specific trends.
