Blended remote sensing tools for house management

Evaluating quality of remote sensing-based agricultural water productivity data

“…CWP has seldom been measured at in-situ level for the assessment of agricultural performance. Rather, in-situ measurements to monitor its components, yield and evapotranspiration, have been a common way to understand, monitor, and benchmark implications of the environment (Arora et al 2011;Pinter et al 2003;Ali and Talukder 2008) and climate conditions (Sadras, Grassini, and Steduto 2007) as well as on farm management practices (Rockström and Barron 2007;Geerts and Raes 2009;Arora et al 2011;Noellemeyer, Fernández, and Quiroga 2013) on crop growth and water consumption. In-situ measurements are limited in their ability to monitor crop conditions over extensive areas due to their considerable costs and resource demands.…”

“…CWP is defined here as the ratio of beneficial biomass to ETIa. The CWP can vary based not just on management and irrigation practices (Pinter et al 2003;Oweis and Hachum 2003;Bossio et al 2008), but on climate (Sadras et al 2007;French and Schultz 1984), crop cultivar (van Wart et al 2013) and other environmental factors (Hatfield, et al 1984;Ali and Talukder 2008;Kijne et al 2003) therefore it is assessed at only one level, between irrigation plots. The beneficial biomass is taken as the AGBP.…”
