Impactos ambientais da implantação do sistema de Produção Agroecológica Integrada e Sustentável (PAIS) em unidades familiares do Distrito Federal.

Abstract

The objective of this study was to evaluate the environmental impacts resulted by the implementation of the technology Integrated and Sustainable Agroecological Production (PAIS) in familiar units in Federal District. The study was conducted in 26 production units that were divided into three groups: Group A, in accordance with organic production; Group B, in agroecological transition without certification; and Group C, of subsistence. For data collection, the AMBITEC AGRO - Sustainable Production System was organized in general aspects, indicators and variables of the environmental dimension, which attributed to each variable a value that represented the change provided by the implementation of the technology. The statistical analysis included the calculation of the Percentage of Environmental Impact of Technology (PIT), which reports, in a practical way, the percentage gain of technology of each unit, and the Wilconxon test, identifying the most significant indicators. The environmental evolution was observed with the implementation of the technology, obtaining a PIT for Group A of 24.8%, Group B of 21.3% and Group C of 17.3%, which contributed to the increase in soil quality and reduction in the use of inputs, positively affecting the three groups evaluated.
