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.

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.

Our analysis evaluates two hypotheses. The ‘urban migration’ expectation asserts that urban experience is important for DALR participation, which links rural and urban areas via migration for land occupations. The ‘DALR efficacy’ hypothesis argues that migration and DALR are complementary livelihood strategies, such that participation in DALR obviates the need for further migration. Our findings support both hypotheses and bear implications for regional development and environmental change in the Amazon.

More recently, direct-action land reform (DALR) settlements have proliferated, which are leading to new forest clearing in the name of agrarian reform. The emergence of DALR begs questions about social and environmental outcomes in recent Amazon settlements. This paper compares DALR settlements in two different regions of the eastern Amazon: the South of Pará and the Transamazon. Analysis of household survey data shows that DALR settlements in the two study areas differ substantially in terms of their histories of formation and regional contexts. However, social and environmental outcomes do not always differ among the two study areas, which in turn resemble older SLAR settlements.

Despite billions of dollars spent on economic development and the rapid pace of urbanization, deforestation is extreme and violent land conflict is intense. 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 argues that the nature of land conflict in the eastern Brazilian Amazon is dynamic, and proposes a two-stage model to illustrate how the struggle has evolved from an agrarian phenomenon to an organized resistance that is urban-based. Recognizing the interaction between cities and rural areas in the frontier reaches of the Brazilian Amazon is key to understanding the land struggle in the face of urbanization. The analytical framework deployed considers the transformation of the region from an agrarian frontier to an urbanized frontier, assessing the dynamic nature of the land struggle and examining the implications for land cover change.
