Abastecimiento de alimentos producidos por la agricultura familiar en la alimentación escolar en Costa Rica: Potencialidades y limitaciones Marianela Zúñiga-Escobar Catia Grisa Gabriela Coelho-de-Souza Estudios Territoriales Agricultura Familiar Alimentación escolar Abastecimiento institucional Sistemas alimentarios sostenibles Seguridad alimentaria y nutricional La alimentación escolar ha sido considerada como un mecanismo de reconexión entre la producción de la agricultura familiar y el consumo de alimentos, siendo un punto de encuentro entre la alimentación pública y el desarrollo sostenible. En ese proceso cobra interés el funcionamiento del Programa de Abastecimiento Institucional (PAI) en el ámbito del Programa de Alimentación y Nutrición del Escolar y del Adolescente (PANEA). El objetivo de este artículo es analizar las principales potencialidades y limitaciones del proceso de abastecimiento de alimentos producidos por familias agricultoras en la alimentación escolar en Costa Rica. Se realizó una investigación cualitativa con entrevistas semiestructuradas y grupos de discusión con participación de diversos actores involucrados en dos proyectos piloto (2016- 2018) de la iniciativa Escuelas Sostenibles en las localidades de Frailes de Desamparados y Coto Brus. Como resultado se evidenció que las principales limitaciones radican en la falta de mecanismos que proporcionen un trato diferenciado de abastecimiento de alimentos producidos por familias agricultoras locales. Por su parte, las experiencias potenciales del proceso se expresan en valores que sobrepasan los aspectos económicos, que se presentan en manifestaciones socioculturales y éticas generadas durante el recibimiento de alimentos en los centros educativos, respondiendo a la construcción social de mercados que caracteriza a las compras públicas de alimentos. 2020 artículo científico 1414-7106 https://www.redalyc.org/articulo.oa?id=552064726004 https://www.redalyc.org/journal/5520/552064726004/ https://www.redalyc.org/journal/5520/552064726004/html/ https://www.redalyc.org/journal/5520/552064726004/552064726004.epub https://www.redalyc.org/journal/5520/552064726004/movil https://doi.org/0.17058/redes.v25i2.15086 es http://www.redalyc.org/revista.oa?id=5520 Redes.
