In Brazil, public food security policies include the National School Meals Programme (PNAE), the Food Acquisition Programme (PAA), at the federal level, and the Programme for the Purchase of Production from Agriculture in the Federal District (PAPA/DF), at the district level. This work analysed the impact of the latter (PAPA/DF) on the adoption of managerial practices and more appropriate production technologies by the group of family farmers participating in this policy, as these innovations have a recognised relationship with their performance. The baseline was obtained from a 2009 database on these producers. In 2016, producers participating in the programme were interviewed, applying a similar questionnaire, aiming to identify changes in management and production processes from 2009 to 2016. The results indicate positive changes in managerial innovation (planning and management processes) and technological innovation (adoption of recommended technologies) in these systems, and also in variables that can influence these results (production and producer characteristics).
