Unveiling Karnataka’s Atmospheric Dynamics: A Comprehensive Study on Vapor Pressure Deficit

Received Date:27 February 2024, Accepted Date:27 June 2024

Abstract

In numerous agricultural domains, primary factors contributing to diminished yield encompass elevated temperatures and inadequate water availability. Moreover, the water equilibrium within plants is significantly influenced by the escalating atmospheric Vapor Pressure Deficit (VPD), culminating in adverse effects on growth and productivity (1). The comprehensive evaluation of VPD in Karnataka over the preceding 35 years has been accomplished through multidimensional data analysis. Geospatial and temporal scrutiny of VPD was conducted employing the Mann-Kendall analysis, thereby corroborating its trends via Z-score, P-value, and Sen-slope measurements. This investigation aims to delineate the trajectory of VPD over the 35 years (1986-2020) in Karnataka, employing a multidimensional approach. As per the findings, notwithstanding seasonal fluctuations in VPD contingent upon vegetation dynamics in Karnataka, the overarching trend of annual VPD has exhibited a declining trajectory over the past three and a half decades.
