The main objective of the present investigation was to understand how peasants of San Juan de Sumapaz re-exist while building territory in defense of life. To achieve this, a conceptual and methodological framework was created that by denouncing the ontological, epistemological and territorial colonialism present in AbyaYala / Latin America, and it assumed given knowledge as a co-extensive experience of subjects and social reality as a communication network that generates meanings, from which historical research was chosen around the categories of re-existence and territory as articulating elements of territoriality, territorialization, territorial order, conflict and conflictivity. This way the ethnographic work, semi-structured interviews, press reading and participant observation emphasized in the processes and transformations, the better understanding of relationships and articulations between practices and discourses. Based on the above, the research showed the existence of multiple communities in AbyaYala / Latin America which are inserted into the capitalist system, not only are opposing to it, but also make its particular practices elements for the defense of life. Following this logic it was demonstrated that in San Juan de Sumapaz exist a struggle between two conflicting territorial orders that has determined the different clashes experienced in in the construction of the territory during the last century, and finally in the XXI century the re-existence of a community that sharing a common context of meanings becomes counter and alter-hegemonic by building forms of collective participation and production, solidarity, self-managed in defense of the ecosystem of paramo and life.
