Abstract Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources. Even though agriculture depends mainly on ecosystem resources and services, its development has been apparently centered only on yield, not considering neither the ecological value of the negative externalities nor the decapitalization of the resources that influence sustainability. Thus, the information on the evaluation of the sustainability on different agriculture styles is scarce or almost null. This investigation evaluates the sustainability in different agriculture styles (intensive horticulture, traditional farm and self-sustaining horticulture) established in Hualqui (Region of Biobío, Chile), through the energy... |

The main objective of this communication is to review the theoretical ecosystem and agroecosystem services assessment’s methods and to propose a thermoeconomic approach. The logic of thermoeconomic approach consists in analysing the use of natural resources during the production process, interpreting it as a thermodynamic conversion in order to assess the overall specific energy consumption of the systemic components arriving at estimates of fluxes and energy costs. This study analyses comparatively the main thermoeconomic-based approaches to verify the feasibility of the "energy value" as an appraisal criterion of agroecosystem services. In particularly among the reviewed approaches the Emergy synthesis seems the most appropriate tool to be empirically... |
