This paper uses the themes of language rights, language choice, and language risk to consider linguistic insecurity in the Northwest Amazon (Upper Negro river) region of Brazil. Because the region is home to a large number of languages (c. two dozen), the idea of preserving this diversity is a popular theme in discourses about language in the Upper Negro river. I argue that the ideologies underlying the goal of preserving 'diversity' as a concept are not, in fact, the same ones that have sustained the presence of these languages thus far, especially as concerns the Tukanoan languages of the Uaupés basin (Jackson, J. E. 1983. The Fish People: Linguistic Exogamy and Tukanoan Identity in Northwest Amazonia. Cambridge, UK: Cambridge University Press). Paradoxically, the reification of 'diversity' as a characteristic of the Northwest Amazonian Indigenous population has tended to promote homogenisation among groups that have historically valued differentiation from one another. In examining ideologies and practices surrounding each of the three themes of this issue, I suggest that discourses of 'diversity', applied at the local level, can create complex outcomes for the languages they are used to promote.

Amazonia is one of the world's most vulnerable regions to climate change but few studies pinpointing priority areas for local adaptation programmes exist. This paper aims to identify socio-climatic hotspots among the 515 municipalities that compose the Brazilian Amazon by using a three-step process. First, we identified the regional social hotspots, that is, municipalities that have currently low adaptive capacity, by calculating a composite infrastructure index based on the assessment of both current green and socioeconomic infrastructures. Second, we used a Regional Climate Change Index to identify the climate change hotspots, that is, those municipalities that have a high likelihood to experience future climate change risks. Third, we evaluated the geographic coincidence of social and climate change hotspots to identify the socio-climatic hotspots. We found that 117 municipalities are regional social hotspots and that 60 municipalities are regional climate change hotspots. Forty-six municipalities are considered as socio-climatic hotspots because they have very low to low composite infrastructure indices and very high climate risk indices. Local institutional capacity to integrate and execute national-level policies that enhance local adaptive capacity is a major constraint across the region. To face the challenges associated with climate change, municipalities in the Brazilian Amazon should embrace a more sustainable development model. Sustainable development, in the context of the Brazilian Amazon, implies conservation of the existing green infrastructure through the expansion of protected areas and indigenous lands, restoration of green infrastructure in areas of deficit, and substantial investments in urban socioeconomic infrastructures to foster a knowledge-based economy. Although local sustainable development and adaptation plans are essential across the entire region, the 46 municipalities identified in this study as regional socio-climatic hotspots could be prioritized for action.

International boundaries in the lowland Amazon forest were historically drawn according to the scramble for natural resources. This paper uses a case study from the Peruvian and Brazilian border and the Ucayali and Jurua watersheds to understand the political ecology of a border process from contact to 2004. Results demonstrate how global resource demand and ecological gradients drove boundary formation and the relocation of indigenous labor to the borderlands. Forgotten in the forest after the fall of rubber prices, the borderland Ashaninka emerged to challenge loggers incited by the global demand for high grade timber. The transboundary impacts of this resource boom highlight discrepancies between the Brazilian and Peruvian Ashaninka's ability to mobilize power. A transboundary political ecology framework is necessary to grasp the heterogeneity and dynamism of natural resource management along boundaries and borderlands forged and tempered by historical resource booms.

Regional and hemispheric reconfigurations in Latin America and the Caribbean are increasingly mediated by Brazilian power, and the engagement of Guyana, Suriname and French Guiana with this emerging context is intriguing. They are tentatively moving away from a Caribbean region with which they are culturally contiguous, towards a South American continent in which they are geographically located. This is partly a reflection of the gradual opening up of the Northern Amazonian space that they share collectively, and also with Venezuela and Brazil. These processes are occurring as cause and effect of Brazil’s emergence as a regional – and even regionally hegemonic – power. With reference to wider debates on regionalism and hegemony, we analyse the uncertain consequences of these shifts. [ABSTRACT FROM PUBLISHER]

Pollen rain studies in Amazonia are scarce but of utmost importance to support interpretations of pollen records. We have investigated modern surface pollen spectra and vegetation in an Amazon location, Carajás, Brazil, where open and woody types of vegetation, swamps and lakes develop under rock outcrops. Both plant inventories of different savanna types along with bryophytic surface samples were analysed with ecological ordination. The results point to taxa that can be used in the differentiation of dry and flooded systems within the savannas studied. Dry savannas, either open or wooded, are indicated by the herbsCuphea, Asteraceae,Borreria, Caryophyllaceae and Polygonaceae, and by woody taxa such as Myrtaceae,Byrsonima, Sapotaceae,Neeaand Rubiaceae. Flooded savannas (swamps) and lakes are indicated by herbs likeSagittaria,Montrichardia,Nymphaea, Cyperaceae andMimosaand palms. Poaceae was found to have a bipolar signature, and using it as an indicator should be done with caution. [ABSTRACT FROM AUTHOR]

This article asks what happens when the colonial dream of a road does not materialize as intended, and becomes instead a permanent project for distant state managers and rural Amazonian settlers. Roads have featured prominently in Brazil’s development designs, and ethnography along an unpaved road demonstrates how a wide array of actors negotiate the tension between the material challenges of moving in Amazonia and the bold modernist figurations that guide highway construction and territorial planning. Over the past 40 years, the unpaved road has itself become a central but unpredictable player in the plans and practices of colonists as well as in emerging governance projects of the Brazilian state. Colonists’ arrival in the region via what they perceive to be an abandoned and impassable road repositions their prefigured relationships with the histories, narratives, and infrastructures of colonial occupation and state-making. Newly local to a frontier zone not yet ‘connected’ to the rest of Brazil, colonists leverage an intimate knowledge of roadside material conditions in an effort to anticipate and influence future state actions.

Located at a strategic crossroads of eastern Amazonia, Marabá has long been known as a volatile, even violent Brazilian boomtown. This study examines the city's sense of place with regard to alternative perceptions of the regional frontier experience: the unstable, resource-extractive “hollow frontier”; the linear, sequential “development frontier”; and the hybrid, socially segmented “post-frontier.” By asking whether, why, and how such understandings resonate with residents, we highlight the social dynamics of place-making. Our interviews suggest that distinctive frontier visions reflect residents' socioeconomic positions and relationships to state-promoted, capital-intensive investment projects. These findings help to explain why citizens favor or oppose dominant forms of regional development. [ABSTRACT FROM PUBLISHER]

The policy intervention to enforce property rights and control deforestation frontiers is often undermined in the Brazilian Amazon, and this intervention problem is considered to be stemming from weak frontier governance. However, little has been understood how this governance can be strengthened in the context of social change. Drawing on a literature review of the Amazon development and sociological studies of space, this article argues that frontier governance is characterised by the co-generation of two territorial processes: the official settlement implementation (physical spacing) and the spontaneous settlers' shaping of the vernacular community (production of place). The co-generation process opens new deliberative space where both state and non-state actors claim authority over the intervention. Therefore, strengthening frontier governance involves empowering this emerging authority to be able to promote public engagement with sustainable development on the frontier. The article uses the regional history and ethnographic material collected in the southeast of Para to illustrate the discussion. [ABSTRACT FROM AUTHOR]

Background: In many developing countries overweight, obesity and obesity-related morbidity are becoming a problem of increasing public health importance. The purpose of this study was to investigate differences in body size and body composition with age in adults of the Caboclo populations from the Brazilian Amazon as well as to examine the prevalence of overweight and obesity in adults aged 20–75 years, taking into account recent trends for the whole country. Caboclo are genetically and culturally admixed rural peasant groups that live along the Amazon River and its tributaries in Brazil, and there are few previous studies of their health and lifestyle. Subjects and methods: A total of 304 subjects (149 males and 155 females) from two socioecologically different areas were studied. Height, weight and skinfolds (tricipital, subscapular and suprailiac) were measured; international intervals (WHO) for overweight and obesity were used. Results: Women showed significantly lower values than men for height, weight, upper arm circumference and fat-free mass and higher values for triceps, subscapular and suprailiac skinfolds and body fat (%). In the overall sample combined overweight and obesity was 47.8% in men and 50.8% in women. When compared to recent values published for the Northern region and for the whole of Brazil, 20.5% of Caboclo women aged 20–75 years were obese, which is higher than all other populations, including other rural samples. Caboclo men showed the highest rates of obesity (9.1%) and overweight (39.1%) of any rural population from the country, including Northern Brazil. Conclusion: The results suggest an effect of increased Western lifestyle influence on the body composition of these Caboclo populations. Considering that these are rural populations with limited access to education and health care, the high prevalence of overweight and obesity associated with low socio-economic status makes them a vulnerable group that deserves a higher level of attention by the country's public health authorities.
