This article focuses on the food supply chain and aligns with the United Nations Sustainable Development Goal of Zero Hunger. They are looking to avoid food waste where Smart Cities must work. Food waste requires innovation with technology to change consumer's behaviors, efficient supply chain management, and innovative food production systems not to harm the environment. Among the economic impact, water and carbon footprint affects vital performance indicators into a Smart City. Hence, this work considers water and carbon footprint, as well as economic impact. We contribute to the Smart Cities, providing a multi-Agent simulation able to be scaled with an ontology with the purpose to plot different scenarios to stakeholders in a Smart City and help to avoid food waste situations. To simplify the simulation, as preliminary work, we used a typical food in Guadalajara Metropolitan Area, which is a Taco. The model covers a community in the Zapopan Municipality, where a developed urban study is the first proof of the system's concept. Furthermore, based on the simulation scenarios fed with real, local data, we discussed how we can integrate this multiagent platform to face COVID-19. Finally, we want to help family businesses on the food supply chain using information technologies and applying digital processes to better adapt to new operation rules since COVID-19 to fight food waste since COVID-19.

El objetivo del presente trabajo es analizar la incidencia en las exportaciones no petroleras de nuestro país debido a las preferencias arancelarias del Sistema Generalizado de Preferencias (SGP) por parte de Estados Unidos. Para el efecto, se utiliza la técnica de observación indirecta mediante la revisión de información estadística de las exportaciones no petroleras de los últimos cinco años. Entre los resultados obtenidos se evidenció los movimientos económicos y comerciales de los principales productos a beneficiarse conjuntamente con su cadena de comercialización. Se concluyó que Estados Unidos sigue siendo nuestro principal socio comercial, a pesar de no contar con el SGP, aproximadamente el 20% de las exportaciones no petroleras del año 2021 fue a este país, se beneficiaron productos como flores de verano, pulpas de frutas, elaborados de madera, entre otros.
