“…For instance, de Faria and Jaramillo’s study (2017) went beyond the Brazilian Amazon and looked at the potential for renewable energy generation across Brazil. Likewise, Lupinetti-Cunha et al (2022) and Tisler et al (2022) both used the geographic extent and project type to model the effects of roadless areas on land cover change and conservation in Brazil. Beyond Brazil, Flecker et al (2022) used location and technical information about hydropower dams to investigate how environmental impacts from damming could be reduced.…”

New infrastructure projects are planned or under construction in several countries, including in the bioculturally diverse Amazon, Mekong, and Congo regions. While infrastructure development can improve human health and living standards, it may also lead to environmental degradation and social change. Accessible, high quality data about infrastructure projects is essential for both monitoring them and studying their social and environmental impacts. We investigated the availability and quality of data on infrastructure projects in the Brazilian Amazon by reviewing the academic literature and surveying researchers from the conservation and development community, then used the results of these surveys to identify critical data attributes for the gathering, organizing, and sharing of infrastructure data by social-ecological researchers and practitioners.Although data on infrastructure in the Brazilian Amazon were generally available, they were often of poor quality and lacked information critical for monitoring and research. Data were often difficult to find and reformat, resulting in loss of time and resources for researchers and other stakeholders. Discrepancies between researchers’ survey responses on data needs and the types of data used in peer-reviewed articles on infrastructure projects indicate the following information was often missing: geographic extent of the project, construction and operation dates, and project type (e.g., paved vs unpaved road). Including these data in a standardized format, along with making them more readily accessible by hosting them in public repositories and ensuring they are current and comprehensive, would facilitate research and improve planning, decision-making, and monitoring of existing and future infrastructure projects in Brazil and other developing countries.HighlightsInfrastructure projects across the globe spur economic development but also lead to social- ecological degradation.Researchers and practitioners need current and comprehensive data to better mitigate social- ecological changes from infrastructure.Infrastructure data are often unavailable, inaccessible, or incomplete.Finding and organizing datasets cost researchers hundreds of hours and may lead to abandoned projects.To promote better research outcomes, governments and NGOs should ensure datasets on infrastructure are accessible, current, comprehensive, and include such vital information as the project’s geographic extent, dates of construction and operation, project type, and essential technical data.

“…The series was generated through automated classification using satellite imagery and machine learning techniques. We incorporated the Brazilian Roads Map, including paved and unpaved roads data (Lupinetti-Cunha et al, 2022). 9 BAPTISTA et al 9…”

“…We hypothesized that agricultural lands cause isolation by resistance (IBR), while paved roads lead to isolation by barrier (IBB). We expected a barrier effect from paved roads but not unpaved roads, given the higher human influence near paved roads (Lupinetti-Cunha et al, 2022;Tisler et al, 2022). Finally, we considered isolation by distance (IBD) as a plausible model only if neither of these landscape elements had a substantial effect.…”

Modified landscapes can restrict the movement of organisms, leading to isolation and reduced population viability, particularly for species with extensive home ranges and long-distance travel, such as white-lipped peccaries (WLPs,Tayassu pecari). Previous studies have indicated that forested areas favor WLP herd movements, but the impact of the non-forested areas on their genetic connectivity is unknown. In this study, we used land cover, the Brazilian Roads Map, and population genetic data to investigate the impact of non-forested matrices on WLP’s genetic connectivity in the Pantanal floodplain and surrounding Cerrado plateau of central-west Brazil. We compared isolation-by-distance (IBD), isolation-by-barrier, and isolation-by-resistance models and tested 39 hypotheses within a modeling framework. Finally, we identified the optimal areas for ecological corridors based on the most effective landscape model. Barrier and landscape resistance were more strongly correlated with genetic relatedness than the IBD model. The model that received the most robust support considered only forest as habitat. All other classes formed a matrix that impeded gene flow, including agriculture, grassland, savannah, and paved and unpaved roads. WLP herds living in landscapes with reduced forest cover are more vulnerable to the effects of genetic isolation. To maintain gene flow, it is essential to establish connections between habitats throughout the landscape. Conservation programs should prioritize strategies that strengthen connections between habitats, including facilitating wildlife road-crossing structures and creating/restoring ecological corridors to link isolated habitat fragments.

“…Roads are one of the main factors that isolate PAs, by restricting the movement and dispersion of animals (Newmark 2008). This problem is even worse with more developed roads (i.e., 4-lane paved roads are more developed than single-lane paved roads, which are more developed than dirt roads), which increase the risk to PAs and reduce the efficiency of PAs closer to roads in maintaining biodiversity (Lupinetti-Cunha et al 2022). Thus, the expansion of the road network puts these areas at risk, as it tends to favor deforestation and habitat loss (Aguirre et al 2021), mainly by making the regions more accessible, which drives deforestation (Barber et al 2014).…”

Analysis of scientific production and knowledge about wildlife roadkill in Brazilian protected areas

Roads are responsible for great biodiversity loss, especially in protected areas (PAs). Thus, considering the great risk of roads to PAs and the lack of knowledge about these areas, we aimed to analyze the scientific production on wildlife roadkill in Brazil and compare the studies that surveyed roads with and without PAs. We searched for papers in five databases: SciELO, Google Scholar, Reet Brasil, Scopus and Plataforma Lattes. Studies considered to be near PAs (PPA) collected data within a radius of 1km of PAs and the other studies were considered to have no PA (NPA). We found 126 studies that surveyed wildlife roadkill in Brazil, of which 57% are PPA. Publications on wildlife roadkill have increased in recent years, with a greater number of PPA studies than NPA studies (W = 618, p = 0.5992). Mammals are the most-studied group (n = 108), followed by reptiles (n = 79), birds (n = 73) and amphibians (n = 58). Most of the studies took place in the Cerrado (54) and the Atlantic Forest (45), where are the greatest number of surveyed PAs, greatest number of PAs and greatest number of PAs without studies. Only 18 papers suggest specific mitigation measures for the study site. The increase in PPA studies is positive, but researchers need to increase contact with PA managers to produce scientific knowledge and develop more efficient mitigation measures for these areas. We encourage increased surveying of roads near PAs, involvement of researchers with environmental agencies, and more studies with small animals.
