La capacité d'action collective des populations marginalisées dans le cadre des stratégies de lutte pour la reconnaissance : les cas de Cité de l'Éternel à Port-au-Prince (Haïti) et de la Sierra Santa Catarina (Mexico)

This thesis analyzes the collective action of marginalized populations located respectively in Cité de l’Éternel» in Port-au-Prince (Haiti) and in « Sierra Santa Catarina », Iztapalapa (Mexico City). In Port-au-Prince, before the fall of the dictatorship of Duvalier, the “tontons macoutes” invaded a terrain located on the edge of the quay of the capital, close to the boulevard Harry Truman. After being installed there, they proceeded to sell of lots intended for the construction of private housing. But after the fall of Jean-Claude Duvalier, in 1986, a part of the population took the opportunity to invade what remained of these marshes. After the occupation, they organized collectively to defend their property before undertaking actions to bring services and to obtain the regularization of their situation.  In the Sierra Santa Catarina (Mexico) populations led by militants of the Popular Front occupied ground at the foot of a sandy mountain in order to build their homes. Like the populations of «Cité de l’Éternel », these people organized to keep watch in order not to be evicted by the police. While working to gain access to the basic services, they undertake actions at the public institutions in order to obtain the regularization of their situation. In relation to the capacity for collective action of these populations, sociological theories are divided. On one side, certain authors support the thesis of the incapacity of these populations to have collective interests and to act consequently. According to them, without social mediation and without aggregation and a political representation, these populations are unable to acquire a collective subjectivity. Other authors think that at the basis of ties of friendship, family and vicinity, independently of their socio-economic situations, these populations can create strategies of subsistence and fight to find solutions that are individuals as well as collective. Concerning populations that invade territory to establish their homes, their actions are already a form of collective action. They are also involved in collective action either to bring basic services such as water and electricity, or to obtain public recognition of the invaded territories. This recognition implies not only the installation of regular services for the benefit of the population but also the granting to each owner of title. In the case of the Sierra Santa Catarina the actions undertaken with respect to public institutions, while in the case of Port-au-Prince, NGO’s or cooperation agencies are directly implicated.  We cannot conclude that populations are unable to have a collective subjectivity and shared interests without an aggregation and a political representation. Starting from various bonds between the individuals, associations are created which make it possible to establish mediation between the populations and other organizations. In the case of the Sierra Santa Catarina, collective action is certainly instrumentalised by leaders. That is part of a political tradition in Mexico. Nevertheless, some settlements people manage to resist their leaders. A part from  the socio-economic situation, the influence of certain leaders in Mexico and the indifference of the State (in the case of Port-au-Prince, in particular), these populations show an astonishing critical capacity with respect to their situation as well as their relations with the leaders of associations and the settlements. This suggests possibility for autonomous critical collective action where circumstances allow  Keys words: marginalization, collective action, recognition, smartness, critical capacity, slums fragmented recognition, denial recognition
