Abstract: We explore the agroecosystem energy flows in two former communist countries, Czechia and Poland, in the two decades after the fall of the totalitarian regimes. Energetic agroecosystem productivity, i.e., the energy content of crops, livestock products per unit of area is compared to energy inputs, i.e., external inputs from society, i.e., labour, industrial inputs, and external biomass inputs and linked to land use change and demographic and economic changes. Using the social metabolism concept and the Material and Energy Flow Accounting method, our analysis looks at the system from a biophysical perspective and explores the interactions between the economic system and nature. We calculate the Energy Return On Investment (EROI) indicators and also present an easily understandable index for policy makers, the Input/Output Index.
