This work possesses the singular importance for the understanding of the fundamental and principle concepts of social inclusion. The institution, FAMFS - Fundação de Apoio ao Cidadão e Mobilização Social, situated in Feira Santana, in the state of Bahia, Brazil, was chosen as the -case study-. The results of this work filled important gaps in related studies to social inclusion associated with the provision of sports and other parallel actions. This is an interesting ethnographic study with documentary analysis, filled with interviews that punctuate the perception of results through the experiences of those involved. This work has made an effective contribution to the debate on the indispensable use of knowledge about public policies and their relation with the Third Sector. It presents a worthwhile investigative process which has resulted in a rich source of content for researchers, public managers and social agents who want to use sport as an instrument to promote social inclusion. Prof. Dr. André Luiz Teixeira Reis Associate Professor I School of Physical Education University of Brasilia - Brazil This book is a true moment of joy and recognition, offering society inspiring learning that motivates us to transform everything contained in this work into actions, in practices to offer our contributions, seeking humanity with more equality in offering opportunities, since, from there, everyone will be able to develop their potential and allow others what was offered to them. Easy to understand, but deepening in the theme, "Sport and Social Inclusion in contexts of vulnerability: an ethnographic approach", makes us reflect on the role that every citizen must assume to enable similar opportunities for individuals to be able to develop their potentialities, and more, that they also become agents of change, offering the same chances to others. At the moment that we are going through a pandemic that severely widens inequalities, this work arrives in time to inspire and instigate the reader for an activity that will be a differential element in overcoming this sad period.
