The purpose of this research was to estimate the environmental impacts between agroecology food system and conventional system using the tomato as product of research, through the analysis of the Life Cycle for the agricultural phase, at La Esperanza and Tabacundo parishes, which are located at Pedro Moncayo canton, to carry on this research it was used calculation of Water Footprint, Carbon Footprint and the analysis of physicochemical parameters in water, soil and product. For the calculation of Water Footprint, the methodology described in the manuals of the Water Foodprint Network was used at the same time with the FAO CROPWAT 8.0 program, while the calculation of the Carbon Footprint was carried out using the guidelines of the IPCC 2006.
We worked with six plots in total, 3 agroecology plots and 3 conventional plots, in terms of the Water Footprint it was found that an agro-ecological tomato crop needs 41,11 liters of water/kg of product while a conventional crop requires 59,57 liters of water/kg of product. For the Carbon Footprint, emissions of 4,59 gCO2eq/kg of tomato were determined in the agroecological system compared to 22,67 gCO2eq/kg of tomato in a conventional system. As a result physicochemical analysis show that in the soils of agroecological crops have 3,08% of organic matter, while the soil of a conventional crop have 1,58%. Regarding the conductivity of the water, an average of 15,82 mS/m was found in the agroecological system, while in the conventional system it was 18,47 mS/m and in tomato there were not any pesticides found. |
