Abstract

A thermodynamic approach for water-energy-food nexus quantification is presented, and its application is demonstrated. Appliyng irreversible thermodynamics of steady-state to the boundary layer between the ecosystem canopy and environment, the entropy production in the main photosynthetic apparatus is quantified. This quantity is used as an intergal quantitative criteria for efficiency of ecosystem functioning. The role of entropy production as a measure for conversion of solar energy in biochemical energy (growth substances) at the specific site environment (microclimate, soil, and topography), species and phenology is motivated. Applying these thermodynamic concept and methods analysis to agrosystems of winter wheat is performed. Analytical description of the accumulated entropy production and crop yield is obtained. Applicability of satellite information from Meteosat in entropy production quantification and yield prediction is demonstrated.
