The leading policy to conserve forest is protected areas (PAs). Yet, PAs are not a single tool: land users and uses vary by PA type; and public PA strategies vary in the extent of each type and in the determinants of impact for each type, i.e. siting and internal deforestation. Further, across regions and time, strategies respond to pressures (deforestation and political). We estimate deforestation impacts of PA types for a critical frontier, the Brazilian Amazon. We separate regions and time periods that differ in their deforestation and political pressures and document considerable variation in PA strategies across regions, time periods and types. The siting of PAs varies across regions. For example, all else being equal, PAs in the arc of deforestation are relatively far from non-forest, while in other states they are relatively near. Internal deforestation varies across time periods, e.g. it is more similar across the PA types for PAs after 2000. By contrast, after 2000, PA extent is less similar across PA types with little non-indigenous area created inside the arc. PA strategies generate a range of impacts for PA types—always far higher within the arc—but not a consistent ranking of PA types by impact.

Birdwatching is a growing segment of ecotourism and South America’s protected areas have an enormous potential to contribute to the development of this activity. We present a simple protocol to assess the potential of protected areas to attract and receive birdwatchers. The protocol is based on the application of raw scores using the following criteria: i) potential of local avifauna to attract birdwatchers, ii) logistic facilities of the protected area, and iii) services for accommodation, communication, health support and transport available in the municipality/ies located near the protected area. The protocol was applied in a protected area located in the State of Acre, in the southwestern part of the Brazilian Amazon. Thirty bird species (11% of avifauna) achieved the highest level of attractiveness for birdwatchers. The protected area and its neighboring municipalities show median capacity for hosting birdwatchers. The application of the protocol in other protected areas will be necessary to improve its applicability. The method, however, could be useful for a preliminary analysis of the birdwatching potential of protected areas.

Social And Environmental Impacts

The dynamics of the systems present in the Amazon require a detailed view of the aspects involving human actions and their consequent interactions with the forest. The impacts caused by this relationship have been the subject of numerous studies aimed at understanding the responsiveness to these impacts, risks, and vulnerabilities of the environment subject to risk factors. The general goal of this paper is to conduct a theoretical and conceptual study on resilience in the face of socioenvironmental impacts in the Brazilian Western Amazon. The specific goals are to contextualize the concepts of situational resilience in the face of environmental impacts, to address the main definitions of environmental impacts in the Amazon, and analyze the approach in the face of the Amazon environmental heritage. Regarding the problem, the following question was proposed: how is resilience characterized in the face of social and environmental impacts? In order to answer this question, a theoretical-conceptual review based on the Contingency Theory was conducted to support the conclusions. In order to reach this goal, we sought the conceptualization of resilience in the face of environmental impacts, the search for the main definitions of environmental impacts in the Brazilian Amazon and some concepts about the Amazonian environmental heritage in a qualitative approach by collecting data through qualitative research for further analysis of the problem and literature review, in order to build knowledge for the theoretical foundation using the Contingency Theory, which springs from environmental conditions to actions that minimize the impacts of human action.

Although mining plays an important role for the economy of the Amazon, little is known about its attributes such as area, type, scale, and current status as well as socio/environmental impacts. Therefore, we first propose a low time-consuming and high detection accuracy method for mapping the current mining areas within 13 regions of the Brazilian Amazon using Sentinel-2 images. Then, integrating the maps in a GIS (Geography Information System) environment, mining attributes for each region were further assessed with the aid of the DNPM (National Department for Mineral Production) database. Detection of the mining area was conducted in five main steps. (a) MSI (MultiSpectral Instrument)/Sentinel-2A (S2A) image selection; (b) definition of land-use classes and training samples; (c) supervised classification; (d) vector editing for quality control; and (e) validation with high-resolution RapidEye images (Kappa = 0.70). Mining areas derived from validated S2A classification totals 1084.7 km2 in the regions analyzed. Small-scale mining comprises up to 64% of total mining area detected comprises mostly gold (617.8 km2), followed by tin mining (73.0 km2). The remaining 36% is comprised by industrial mining such as iron (47.8), copper (55.5) and manganese (8.9 km2) in Carajás, bauxite in Trombetas (78.4) and Rio Capim (48.5 km2). Given recent events of mining impacts, the large extension of mining areas detected raises a concern regarding its socio-environmental impacts for the Amazonian ecosystems and for local communities.
