Territorial Praxis in Vulnerable Communities on The Periphery: Hunger and Sanitation in Perspective: The perpetuation of hunger and basic sanitation problems are felt in different spheres, with repercussions in the expressive increase in the quantities of vulnerable territories. The search for solutions capable of overcoming social discrepancies is urgent and requires broad social and scientific support from universities. In this sense, the present work seeks to present the conception of territorial praxis, understanding it as a key, framed as part of the action research methodology. We present as conclusions that the construction of scientific agendas in a territorial praxis, serves to promote diagnostic actions as well as to instrumentalize and emancipate collective groups in actions to combat the eradication of poverty and its associated dimensions, such as hunger and sanitation problems. Thus, the present text shares initiative and experiences of action research locally referenced in the community of favelinha located in the Parque Analândia neighbourhood in São João de Meriti, Rio de Janeiro (Brazil) Andre Santos Rocha Abstract 10 PDF (Español) 4
