Framing Sustainability in a Telecoupled World

Interactions between distant places are increasingly widespread and influential, often leading to unexpected outcomes with profound implications for sustainability. Numerous sustainability studies have been conducted within a particular place with little attention to the impacts of distant interactions on sustainability in multiple places. Although distant forces have been studied, they are usually treated as exogenous variables and feedbacks have rarely been considered. To understand and integrate various distant interactions better, we propose an integrated framework based on telecoupling, an umbrella concept that refers to socioeconomic and environmental interactions over distances. The concept of telecoupling is a logical extension of research on coupled human and natural systems, in which interactions occur within particular geographic locations. The telecoupling framework contains five major interrelated components, i.e., coupled human and natural systems, flows, agents, causes, and effects. We illustrate the framework using two examples of distant interactions associated with trade of agricultural commodities and invasive species, highlight the implications of the framework, and discuss research needs and approaches to move research on telecouplings forward. The framework can help to analyze system components and their interrelationships, identify research gaps, detect hidden costs and untapped benefits, provide a useful means to incorporate feedbacks as well as trade-offs and synergies across multiple systems (sending, receiving, and spillover systems), and improve the understanding of distant interactions and the effectiveness of policies for socioeconomic and environmental sustainability from local to global levels.

Theorizing Land Cover and Land Use Change: The Peasant Economy of Amazonian Deforestation

Abstract This article addresses deforestation processes in the Amazon basin, using regression analysis to assess the impact of household structure and economic circumstances on land use decisions made by colonist farmers in the forest frontiers of Brazil. Unlike many previous regression-based studies, the methodology implemented analyzes behavior at the level of the individual property, using both survey data and information derived from the classification of remotely sensed imagery. The regressions correct for endogenous relationships between key variables and spatial autocorrelation, as necessary. Variables used in the analysis are specified, in part, by a theoretical development integrating the Chayanovian concept of the peasant household with spatial considerations stemming from von Thünen. Results from the empirical model indicate that demographic characteristics of households, as well as market factors, affect deforestation in the Amazon basin associated with colonists. Therefore, statistical results from studies that do not include household-scale information may be subject to error. From a policy perspective, the results suggest that environmental policies in the Amazon based on market incentives to small farmers may not be as effective as hoped, given the importance of household factors in catalyzing the demand for land. The article concludes by noting that household decisions regarding land use and deforestation are not independent of broader social circumstances, and that a full understanding of Amazonian deforestation will require insight into why poor families find it necessary to settle the frontier in the first place.

Protecting the Amazon with protected areas

This article addresses climate-tipping points in the Amazon Basin resulting from deforestation. It applies a regional climate model to assess whether the system of protected areas in Brazil is able to avoid such tipping points, with massive conversion to semiarid vegetation, particularly along the south and southeastern margins of the basin. The regional climate model produces spatially distributed annual rainfall under a variety of external forcing conditions, assuming that all land outside protected areas is deforested. It translates these results into dry season impacts on resident ecosystems and shows that Amazonian dry ecosystems in the southern and southeastern basin do not desiccate appreciably and that extensive areas experience an increase in precipitation. Nor do the moist forests dry out to an excessive amount. Evidently, Brazilian environmental policy has created a sustainable core of protected areas in the Amazon that buffers against potential climate-tipping points and protects the drier ecosystems of the basin. Thus, all efforts should be made to manage them effectively.

The Amazon Land War in the South of Pará

Abstract The South of Pará, located in the heart of the Brazilian Amazon, has become notorious for violent land struggle. Although land conflict has a long history in Brazil, and today impacts many parts of the country, violence is most severe and persistent here. The purpose of this article is to examine why. Specifically, we consider how a particular Amazonian place, the so-called South of Pará, has come to be known as Brazils most dangerous badland. We begin by considering the predominant literature, which attributes land conflict to the frontier expansion process with intensified struggle emerging in the face of rising property values and demand for private property associated with capitalist development. From this discussion, we distill a concept of the frontier, based on notions of property rights evolution and locational rents. We then empirically test the persistence of place-based violence in the region, and assess the frontier movement through an analysis of transportation costs. Findings from the analyses indicate that the prevalent theorization of frontier violence in Amazônia does little to explain its persistent and pervasive nature in the South of Pará. To fill this gap in understanding, we develop an explanation based on the geographic conception of place, and we use contentious politics theory heuristically to elucidate the ways in which general processes interact with place-specific history to engender a landscape of violence. In so doing, we focus on environmental, cognitive, and relational mechanisms (and implicated structures), and attempt to deploy them in an explanatory framework that allows direct observation of the accumulating layers of the regions tragic history. We end by placing our discussion within a political ecological context, and consider the implications of the Amazon Land War for the environment.

The Political Economy of Land Conflict in the Eastern Brazilian Amazon

Abstract An important goal of regional development in the Brazilian Amazon was to enhance social welfare and alleviate dire poverty in other parts of the country by providing land to the poor. Nevertheless, both poverty and landlessness have persisted despite development policies that distributed billions of dollars on highway construction, loans, and outright subsidies. Inequitable land distribution has been held as a prime factor in land conflict across the country. Although episodes of conflict over land are common in Brazilian history, this paper focuses on agrarian issues that arose with the opening of the Amazon frontier in the 1970s. The paper presents a political economy approach that considers the role of hierarchical forces interacting across spatial scales, in creating conditions ripe for land conflict at the local level. The premise is that the Brazilian government, intending to bring about economic and social development, promoted contradictory strategies creating land scarcity. These strategies led to expansion of large ranching operations, creation of conservation units, and demarcation of indigenous reserves, which constrained the pool of land available for small farmer settlement. Empirical analysis employing regression and spatial statistics is used to test the proposed model, advancing previous efforts by applying spatial regression, incorporating improved indicators of conflict and explanatory variables generated by a Geographic Information System (GIS). The findings provide support for some elements of the argument, demonstrating statistically significant relationships between land conflict and land concentration, cattle ranching, and road construction. Finally, a case study analysis of a county in the heart of the land conflict zone is provided, illustrating the interaction of scalar forces, and the articulation of land conflict at the local level.

Tree planting by small producers in the tropics: A comparative study of Brazil and Panama

Forest regrowth is a notable phenomenon across the tropical forest latitudes. Such reforestation takes place in the wake of land abandonment, occurs cyclically in a rotational agricultural system, and may result from the deliberate planting of trees by farmers. Although less extensive than successional forest regeneration, tree planting by small farmers can have potentially important environmental impacts at both the site and global scale. This paper examines tree-planting efforts by small farmers in the tropical frontier regions of Panama and Brazil in order to gauge the magnitude of reforestation activities, and to identify factors that influence these efforts. This paper discusses the environmental regulations, forestry law, and tenure institutions in both countries, and performs a comparative analysis of reforestation efforts with information derived from household surveys (n = 356) and in-depth tree planting interviews (n = 35). Results from logistic regression are also presented. Our results show that tree planting occurs more frequently in Panama, which we attribute to greater external support in the provisioning of extension and materials and strong market incentives. We suggest that the proximity of the study sites to Panama City facilitates external support and market drivers. Finally, our results suggest that land tenure security is an influential determinant of reforestation activities in both countries.

Contentious Land Change in the Amazon's Arc of Deforestation

Land change in the Amazon is driven by numerous factors including fiscal incentives, infrastructure, transportation costs, migration, and household decision making. Largely missing from the story to date, however, is the role of contentious social processes, including contention over land resources. By employing a case study of land conflict over a largeholding in southeastern Pará, Brazil, and a regional-scale statistical model, we describe contentious land change (C-LC) in an area with a long history of antagonism between largeholders and the rural poor. We fuse the conceptual frameworks of political ecology with the methodological approaches of land change science to show that deforestation in the area of study is enhanced due to the interaction of diverse and adversarial agents rather than the independent actions of isolated land managers deforesting according to the dictates of microeconomic optimization. C-LC is a process of global reach and must therefore be added to the topical range of land change science. A combination of the explanatory richness of political ecology with the methodological rigor of land change science greatly enhances our understanding of land change processes.

Fire In The Brazilian Amazon: A Spatially Explicit Model For Policy Impact Analysis

This article implements a spatially explicit model to estimate the probability of forest and agricultural fires in the Brazilian Amazon. We innovate by using variables that reflect farm-gate prices of beef and soy, and also provide a conceptual model of field management and deforestation fires to simulate the impact of road-paving, cattle exports, and conservation area designation on the occurrence of fire. Our analysis shows that fire is positively correlated with the price of beef and soy, and that the creation of new conservation units may offset the negative environmental impacts caused by the increasing number of fire events associated with early stages of frontier development.

The Local Articulation of Policy Conflict: Land Use, Environment, and Amerindian Rights in Eastern Amazonia

The Brazilian government has promoted development in Amazonia for over forty years. Nevertheless, improvement of rural conditions has been limited. Although tropical deforestation has been the premier concern in discussions about Amazonia, this article focuses instead on the human dimensions of development and the apparent failings of social policy in the region. In so doing, the article argues that what we observe today represents the consequence of conflicting development strategies, brought about by shifting national priorities that were influenced, in part, by international pressures. The article makes this argument by first presenting an overview of development strategies pursued since the mid-twentieth century, followed by a description of shifting national priorities linked to pressures from the international community regarding indigenous rights and environmental concern. Finally, this article presents a GIS-based case study focused on the state of Para, demonstrating the spatial articulation of c...

Forest management practices in the Bayano region of Panama: Cultural variations

Abstract This paper examines the relationship between cultural variation and forest management practices in the New World tropics by presenting results from a survey conducted in indigenous and colonist communities in a settlement frontier of Panama. Statistical analyses, focused specifically on differences between the economic base, forest use, and management practices of indigenous and colonist households, are presented. The findings reveal that there are no significant differences between the indigenous and colonist households in this respect; furthermore, differences that exist among the sample households appear to be linked to access to market and not to cultural variations.
