A análise dos mecanismos jurídicos que regem, na atualidade, a arqueologia brasileira norteia este trabalho. No entanto, seu esforço central é a busca de um modelo de tutela efetiva e compartilhada para o patrimônio arqueológico existente no município de Serranópolis, região sudoeste do estado de Goiás, Brasil. Como proposta para a proteção dos sítios arqueológicos do nominado município, foi elaborado um Plano de Medidas a ser implantado pelo governo municipal, com a colaboração efetiva da comunidade e a participação dos entes públicos estadual e federal, cada um no escopo de suas competências. O presente trabalho foi desenvolvido dentro do Programa de Doutorado em Arqueologia do Museu de Arqueologia e Etnologia da Universidade de São Paulo - MAE/USP, na Linha de Pesquisa \"Arqueologia e Ambiente\". / The analysis of legal mechanisms that rule, currently, the Brazilian archeology guides this work. However, its central effort is the searching for an effective and shared guardianship model to the archaeological heritage in Serranópolis city, located in the southwest region of the state of Goiás, Brazil. As a proposal for the protection of archaeological sites in the said city, it was elaborated a Archaeological Cultural Park Project to be implemented by the Serranópolis\' municipal government, with active cooperation of the community and the participation of state and federal governments, each one in their own competences. This thesis was developed in the scope of the Archaeology Doctoral Program of Museum of Archaeology and Ethnology of University of São Paulo - MAE / USP, in the Research Field \"Archaeology and Environment\".

Les écosystèmes forestiers d’Afrique centrale en général, et ceux du Cameroun en particulier, sont très riches en ressources naturelles. Ils offrent de nombreuses opportunités aux populations pour leurs moyens de subsistance. Cependant, face à la mise en place du processus de développement socio-économique, ce milieu est confronté à de nombreuses menaces, notamment, la déforestation, la dégradation, le braconnage, la pollution, la surexploitation des ressources biotiques et abiotiques, etc. Le législateur camerounais, sous l’impulsion de l’action de la coopération internationale, a adopté plusieurs instruments juridiques internationaux et nationaux prévoyant des mesures de protection des écosystèmes forestiers durant la réalisation des projets de développement socio-économique. Toutefois, l'analyse minutieuse du dispositif normatif et institutionnel mis en place au Cameroun, montre que les mécanismes juridiques de protection des écosystèmes forestiers durant la réalisation des projets de développement socio-économique, quoique pluriels, restent ineffectifs et inefficaces. Beaucoup d’efforts restent encore à fournir sur certains aspects qualitatifs de la législation. L’application des mécanismes juridiques existants ne favorise pas l’atteinte des objectifs d’une protection efficace et efficiente des écosystèmes forestiers. Les problèmes liés aux ressources humaines et financières, de gouvernance forestière, d’incoordination institutionnelle, d’analphabétisme écologique, de la pauvreté généralisée des populations, de conflit entre la tradition et la modernité ont pour conséquence de relativiser l’effectivité et l’efficacité de la protection des espaces forestiers au Cameroun. Pour relever ce défi, il faut nécessairement mettre en œuvre de nombreuses actions, dont les plus pertinentes sont la reformulation du cadre législatif, l’amélioration du système de gouvernance et l’élaboration d’une convention internationale sur les forêts. / The forest ecosystems of Central Africa in general and those of Cameroon in particular, are very rich in natural resources. They offer many opportunities for people in terms of livelihoods. However, faced with the implementation of the process of socio-economic development, this environment is confronted with many threats including deforestation, degradation, poaching, pollution, overexploitation of biotic and abiotic resources, etc. The Cameroonian legislator, spurred by the action of international cooperation, has adopted several international legal instruments and has legislated on measures to protect forest ecosystems during the implementation of socio-economic development projects. However, a careful analysis of the normative and institutional framework put in place in Cameroon shows that the legal mechanisms for protecting forest ecosystems during the implementation of socio-economic development projects, although plural, remain ineffective and inefficient. There is still much work to be done on some aspects of legislation and enforcement of existing legal mechanisms to ensure that forest ecosystem protection objectives are effective and efficient. The problems of human and financial resources, forest governance, institutional incoordination, ecological illiteracy, widespread poverty of the people, conflict between tradition and modernity have the effect of putting into perspective the effectiveness and efficiency of the protection of forest ecosystems in Cameroon. Meeting this challenge requires the implementation of several actions, the most salient of which are the reformulation of the legislative framework, the improvement of governance and the elaboration of an international convention on forests.
