Riberenos' Changing Economic Patterns in The Peruvian Amazon

The changes in the subsistence systems of riberenos, riparian inhabitants, occupying a blackwater river community in Peru's northeastern Amazonia are examined. The riberenos' traditional livelihood has been based on farming as well as the hunting and collecting of forest products. Their increasing dependence upon the market economy is, however, radically transforming the riberenos' swidden-agroforest system and other established rainforest management practices and, in the process, upsetting the environmental balance.

An Historian in the Amazon

However private they may seem, emotions depend for their meanings on the communities in which they are expressed. But if emotions are shaped by and for their communities, how can we account for emotional change? After briefly surveying how historians have (1) defined the communities in which emotions have been expressed and (2) explained how and why emotions have changed, this article turns to the community of the Waorani of Amazonian Ecuador. It explores whether anthropological explanations of emotional change in that “test case” may help the historian. The answer is not entirely positive. The article concludes with some thoughts about what sorts of collaborations between historians and anthropologists might be more productive for emotions studies.     

Soybeans,Development and Conservation on the Amazon Frontier

Bolivia's rate of deforestation throughout the 1990s was among the most rapid anywhere in the Amazon Basin. This drastic clearing stood in sharp contrast to the relatively slow rates of landscape change that had prevailed in previous decades. This article reviews the models used for explaining deforestation, and argues that the new context of globalization, structural adjustment, regional integration and rapid technological change contributed to accelerated forest cutting during the 1990s. The author suggests that many environmental policy approaches developed during the 1970s and 1980s no longer address the current clearing situation effectively, and that today's frontiers differ profoundly from previous ones. The widely held idea that intensive production per se reduces forest destruction may not be valid on tropical agro‐industrial frontiers, such as the soybean zones of Bolivia and Brazil.

Transnational Development on the Frontier: The FAO's Fishery and Forestry Missions in the Brazilian Amazon

In the early 1950s, the UN Food and Agriculture Organization (FAO) organized a mission to the Brazilian Amazon Valley to assess development needs and help implement a development plan. The Brazilian government saw this as part of an initiative to integrate a sparsely populated and ‘backward’ region more firmly into the nation. The FAO's local partner was the Superintendancy for the Plan of Economic Valorization of the Amazon (SPVEA), a regional development agency created in 1953. This article analyzes the operation of the Mission, specifically its fishery and forestry sections, to understand the dynamics of transnational development cooperation. The mission eventually failed because the Brazilian state never offered sufficient support on FAO terms; SPVEA never acquired the necessary financial resources, administrative capacity and technical expertise. The FAO experts recognized the problems, but had no means to enhance the resources or change the approach of the local partner. The government's decision, in the late 1950s, to prioritize the building of a major road from Brasília to Belém, aggravated the lack of resources for the Mission's work. Importantly, the failure was not a question of ideological resistance to foreign meddling or a fundamental opposition to the FAO development strategy.     

The use of the phasor display in studying ionospheric radio echoes

The phase and amplitude of a radio pulse reflected from the ionosphere usually vary during the pulse. It is convenient to observe these variations using the X-Y mode of an oscilloscope to display the phasor of the echo. The variations are then seen as an oval or spiral shape traced out by the end point of the phasor. These shapes provide a sensitive method of detecting the presence of more than one echo, and are useful as a measure of dispersion.     

The population of the Amazon basin in 1492: a view from the Ecuadorian headwaters

"Recent archaeological, ethnohistorical and ecological evidence has begun to challenge the view that 'civilizations' failed to develop in the Amazon basin due to limitations of the tropical forest environment. As a result, estimates of the native population in 1492 have become an issue of debate. These estimates are evaluated in the light of the ethnohistorical research on the Ecuadorian headwaters. Estimates are considered by examining estimated habitat densities, the impact of Old World diseases and contemporary evidence for native cultures. The study is based on documents found in archives in Quito, Seville, Madrid and Rome. It is suggested that the population of the Amazon basin in 1492 probably exceeded 5 million but that expectations of substantially higher populations appear unfounded."     

Analyzing the Spatial Dynamics of Deforestation in Brazilian Amazon

Historically, development in Brazilian Amazon was promoted by permits of deforestation under soft territory control or supervision. However, due to the importance of this biome for biodiversity and ecosystem balance in a global perspective, Brazilian's government has tightened deforestation control. This work investigates the spatial pattern of deforestation in a cross‐section and time perspective using global and local spatial data analysis. Global results indicate the existence of high spatial correlation and that deforestation holds concentrated across space, despite the efficacy of policy mechanisms adopted for controlling and reducing the level of deforestation in Legal Amazon. Furthermore, local results support the hypothesis of high spillover effects. Considering the spatial analysis results, we highlight some implications for policy design aiming deforestation control.

Competing entanglements in the struggle to save the Amazon: The shifting terrain of transnational civil society

Transnational civil society has often been conceptualized as a third sector, buffered from the power politics of nation-states and global capital. The relative autonomy of this sector has been seen as key in empowering the voices of marginalized peoples and in advocating new counter-hegemonic agendas on the world stage. Recent research, however, has begun to explore power imbalances within the transnational civic sphere, and how different transnational NGOs' modes of articulation with political institutions and market actors inform those power dynamics. We suggest here that the concept of “entanglements,” recently introduced within political geography, can offer a useful spatial imagery in assessing the effects of these varied lines of influence. The article first traces the evolution of the Amazon Alliance, a transnational network of environmental and human rights NGOs and Amazonian indigenous federations. It then examines a countervailing nexus of governmental and corporate entanglements that have been drawing conservation NGOs away from indigenous eco-political engagement in recent years. To understand the waning salience of the eco-indigenous conservation agenda, we argue, requires analysis of the shifting terrain of civil society, and of the articulation of different NGOs with institutions beyond the frontiers of the third sector.     

Agricultural Settlement and Ecological Crisis in the Ecuadorian Amazon Frontier

This article discusses several structural factors in the policy environment of Ecuador thought to determine the process of occupation by agricultural colonists of the country's segment of Amazonia and the emerging land settlement patterns in the region. These factors are fundamentally concerned with (a) national sovereignty interests over remote, peripheral territories characterized by low population density and ill-defined land ownership, (b) the reduction of demographic and social pressures in other regions of the country, and (c) the extension of the agricultural frontier. For economic and geopolitical reasons, the Ecuadorian state is likely to maintain a moderate and rather ineffectual set of incentives supporfted by the current legislation to allow the occupation of the Amazon region. Consequently, as migrants continue to flow into the easily degradable areas of the Amazon, and without increased population carrying capacity outrside the Amazon, some conversion of the rainforest environment of eastern Ecuador to other uses is certain to continue. A more detailed microlevel understanding of the interrelationship among factors influencing land-use decisions by settler farmers is needed to find policy-entry points.     

Unofficial Road Building in the Amazon: Socioeconomic and Biophysical Explanations

Roads have manifold social and environmental impacts, including regional development, social conflicts and habitat fragmentation. ‘Road ecology’ has emerged as an approach to evaluate the various ecological and hydrological impacts of roads. This article aims to complement road ecology by examining the socio‐spatial processes of road building itself. Focusing on the Brazilian Amazon, a heavily‐studied context due to forest fragmentation by roads, the authors consider non‐state social actors who build ‘unofficial roads’ for the purpose of gaining access to natural resources to support livelihoods and community development. They examine four case studies of roads with distinct histories in order to explain the socio‐spatial processes behind road building in terms of profit maximization, land tenure claims, co‐operative and conflictive political ecologies, and constraints as well as opportunities afforded by the biophysical environment. The study cases illustrate the need for a multi‐pronged theoretical approach to understanding road building, and call for more attention to the role of non‐state actors in road construction.     

From Para to Manaos: A trip up the lower Amazon

This paper examines the General Elections of 1983, 1987 and 1992 and argues that not only has the SNP increased its share of the popular vote, but that share has become increasingly evenly distributed across Scotland. Thus, the SNP is becoming a truly ‘national’ party, where once it's support was geographically concentrated in areas of reduced class‐conciousness and strong local leaders. This new distribution is accounted for, in part, through the use of the SNP as a ‘protest’ vote.     

The socionature that neo-extractivism can see: Practicing redistribution and compensation around large-scale mining in the Southern Ecuadorian Amazon

In this article I address the complex processes of transformation taking place due to industrial mineral extraction in the Ecuadorian Amazon through a focus on state and company led practices of redistribution, social investment and compensation. The analysis of three empirical examples related to the Mirador industrial mining project is viewed in relation to a more extensive assembling of a mining surface. I introduce the concept ‘surfacing’ to refer to discursive and material practices that state and corporate actors make use of to manage, facilitate and enact a redistributive economic policy, and at the same time produce value in and for the global capitalist market. A main argument is that these practices make certain socio-natural relations visible to the project of large-scale mining while obscuring affected peoples' ‘place-based life projects’. Restricted by neo-extractivist modes of recognition, of ‘seeing’ and ‘not-seeing’, indigenous Shuar, and mestizo livestock peasants, colonos, respond to mining intervention based on their differentiated engagements and trajectories with the Amazonian landscape and ecology. The paper is an intent to understand geosocial transformations and the differentiated practices of non-recognition while analyzing these responses.     

The sound of yesteryear on display: a rethinking of nostalgia as a strategy for exhibiting pop/rock heritage

The increasing presentation of popular music culture as heritage is manifested in the recent proliferation of museums of pop/rock culture. This calls for an examination of the current practices of disseminating pop/rock heritage through exhibitions. Two trends have been identified and criticised by previous commentators: first, the prominence of nostalgia in exhibition narratives and second, that exhibitions of popular music tend to display ancillary objects rather than music itself. This article offers a rethinking of nostalgia as a strategy for disseminating pop/rock heritage and explores the potential of music as a trigger for nostalgic experiences in exhibitions. While agreeing with much of the critique levelled at the nostalgic approach to pop/rock culture, we suggest that with a more nuanced conception of reflective nostalgia, the affective appeal of the nostalgic approach can be harnessed without giving in to glamourised oversimplifications of the past. Further, we suggest that mediated memories can form the basis of nostalgic feelings and thus enable the nostalgic approach to span the generational gap and engage visitors who do not have a lived experience of pop/rock heritage. We will illustrate this by contrasting our approach to that taken at ABBA The Museum.
