This research has as it is principal objective to estimate the environmental impacts generated in the agricultural phase of the agroecological and conventional agri-food chains, in the canton Tabacundo. This work has been made through carbon and hydric footprint indicators, which belong to the climate change category of life cycle assessment (LCA), since these indicators generate detailed information for the farmers to support their products and for them to be valued by the consumers. The analysis was made by physico-chemical parameters of the water and soil from the studied land plots to compare the current resource situation in both agricultural productions.
The results from the research showed that the carbon footprint that 1 kg of broccoli, cultivated in the conventional way, generates 178,53 g CO2eq, whereas the production of 1 kg of agroecological broccoli generated 44,31 g CO2eq. The hydric footprint results showed that to produce 1 ton of agroecological broccoli the amount of water needed was 82,11 m3, however for 1 ton of conventionally cultivated broccoli the amount or water needed was 230,75 m3 .
On the other hand, the percentage of organic matter, important parameter of physico-chemical soil analysis, is higher in agroecologically cultivated soils with 3,54% which shows good physico-chemical soil characteristics, such as water retention, which avoids constant irrigation. For the conventionally cultivated soils, the percentage is 1,71% highly related to soil erosion problems, compaction, low permeability and water retention capacity. |
