Coupling of Evapotranspiration with Anthropogenic parameters -A case study of Central and Eastern India

Abstract

Abstract Through present work district wise coupling of anthropogenic forcing’s with Evapotranspiration (ET) for the years 2001-2010 over Indian state of Bihar and Madhya Pradesh has been identified. Here, calibrated Moderate Resolution Imaging Spectroradiometer (MODIS) annual ET data i.e MOD 16 8-Days ET Product along with different statistics related to agricultural management factors such as Net sown area (NSA), Gross cultivated area (GCA), Agriculture sown area more than once (ASMO), Net irrigated area (NIA), Gross irrigated area (GIA) alogwith Ground water level data were used. And, to identify coupling of ET with selected parameters Mann Kendall trend test statistics and correlation analysis have been performed at district-level. Thus, result thus obtained showed a good coupling and coorelation of ET with selected anthropogenic factors and this noticed coupling factor were covering 46% area of the state Bihar and 50% area of Madhya Pradesh and Correlation coefficient of these parameters with ET were ranging up to 0.9 for both the study states. *Corresponding Author:Shweta Email:swetagpt29@gmail.com Thus, this part of the analysis showed very explicitly that ET was very well coupled with anthropogenic factors which is a good indication in terms of agricultural production, and at the same time shows alarming situation for exploition of irrigation resources for the respective states.
