The agro-ecological transition in the Amazon is a crucial issue for improving the living conditions of rural populations and protecting the environment. Agroforestry systems seem to offer a sustainable alternative as part of this transition. This article analyzes the influence of production dynamics on the agricultural development of two municipalities in the Eastern Amazon, based on their historical and cultural trajectories, in order to understand the role played by territorial specificities in the establishment and dissemination of Agroforestry Systems (SAFs). The research was carried out in the municipalities of Igarapé Miri and Tomé Açu, using exploratory and descriptive research of a qualitative and quantitative nature, interviews with family farmers and observations of their properties. The results show production dynamics specific to each region, influenced by the economic cycles and crises they have been through. This was achieved through SAFs. The analysis shows that the adoption of SAFs in the territories depends on the biophysical environment, because although there are similarities between the productive dynamics, the territories have natural specificities that differentiate between SAFs established in open fields (type A), in terra firme areas, and those established in flooded forests (type F). The decision to establish and disseminate SAFs in family farming is also conditioned by socio-economic factors: production must meet both the family's food needs and market demand, especially at a local level.

The objective of this article is to analyze the institutional dimension of the geographical solidarity in the Sistema Único de Saúde, emphasizing the regional nature of the regulatory power of the norms through the apprehension and operationalization of the concepts of region and regionalization in the documents that subsidize health policy planning in the state of Rio Grande do Norte. Although regionalization has been considered as the structuring axis of SUS since the 1988 Constitution, the vertical normative propositions of the national federated entity and its weak management consolidation in the state federal entity are reflections of the complex organizational structure of the Brazilian federation, which "empties" the locus of regional power while it oscillates between the centralization of the national scale and the decentralization of the municipal scale, generating obstacles for the execution of a territorial pact of health policy.

This paper aims to highlight the potential contribution of the Thematic Cartography to historical studies as an analytical tool of the documentation raised during the research. To do so, the article will begin with a brief introduction about Thematic Cartography and its main methodological aspects, and then to present two examples of its use in academic investigations in the History field. It is sought, therefore, to draw attention to some relevant elements of this tool that can serve the historian in the formulation of new problems for his investigation; in the analysis of the problems already formulated and, mainly, in the construction of the argumentation of his narrative. In the end, it is intended to point out the importance of the use of this instrument in the historical studies, once it is associated with the questions and problems of the research, and not merely for aesthetic or technical reasons.

The incorporation of South Patagonia into Argentina´s territory is the result of dynamics originating in central spaces and associated to the expansion of capitalism over strategic spaces. In line with the military action called “The Campaign of the Desert”, the creation of the first National Parks also assumed geopolitical purposes to consolidate national sovereignty. In the beginning, protected areas were considered fundamental pieces for national development. For this reason, they allowed certain human activities such as livestock, forest exploitation and also human settlements. However, since 1980 these territorial units are categorized by the international standards. In this globalization context, National Parks begin to restrict those historical uses of land, including human settlements. Encouraged by the idea of strong conservation, excluding society, these spaces may be considered responsible for territorial precarious processes. At the same time, the national tourism promoted in the National Parks is changed to answer the international demands. El Chaltén is a small town located southwest of the Santa Cruz province in southern Argentinean Patagonia. It is surrounded by the Los Glaciares National Park (LGNP) which is consolidated as a border to urban expansion. The most relevant territorial problem in El Chaltén is the land access. From a critical perspective, the objective of this article is to uncover the power relations between the agents who appropriate the space in the protected area. Through a qualitative focus, we analyze the processes of land appropriation in El Chaltén and the LGNP based on three jurisdictional conflicts between different actors. The results show that the protected area functions as a border of land access to the population of El Chaltén but it becomes a strategic space for the accumulation and reproduction of capital.
