Urban and peri-urban agriculture has proven to have positive results in alleviating food insecurity in urban spaces, improving sustainability and resilience, and increasing nutritious and safe food access. It reinforces the local identity system and creates new jobs and income opportunities both for the producers and for those involved in the supply chain. It is a process that requires economic and technical support aiming to optimize results. Currently, in Colombia, there are no government policies to support these processes. Therefore, in this paper we provide a contextualization of the most relevant experiences and most useful technical tools to implement urban and peri-urban agroecological orchards. They have an approach to agriculture more related to the environment and socially sensitive, focused not only on production but also on the ecological sustainability of the system. All of this is to transfer this knowledge on crops to various communities of the urban and peri-urban sectors, thus contributing to strengthening their food security from vegetable production. In one of the chapters, they present us the results of the studies developed with communities that have played a fundamental role in the process of recognizing, rescuing, and deploying knowledge based on science and practical exercise. In Colombia, agricultural research is still emerging, therefore, it must be a daily exercise that benefits directly and permanently our communities, small and medium-scale farmers, and their productivity. As a result, we must create more research applied within the framework for technological development.
