Conflicts Over Extractivist Policy And The Forest Frontier In Central America, Anthony J. Bebbington, Laura Aileen Sauls, Herman Rosa, Benjamin Fash, Denise Bebbington
Geography
Central America is characterized by an asymmetric forest transition in which net deforestation is a product of both forest loss and patches of forest resurgence. Forest loss is also associated with rights violations. We explore the extent to which extractive industry and infrastructure investments create pressure on forest resources, community rights and livelihoods. Drivers of this investment are identified, in particular: constitutional, legislative and regulatory reforms; energy policies; new financial flows; and ideas of development emphasizing the centrality of infrastructure in combining geographical integration and economic growth. We discuss forms of contentious action that have emerged in response to these …
Evaluating Wildlife Vulnerability To Mercury Pollution From Artisanal And Small-Scale Gold Mining In Madre De Dios, Peru, K. E. Markham, Florencia Sangermano
Evaluating Wildlife Vulnerability To Mercury Pollution From Artisanal And Small-Scale Gold Mining In Madre De Dios, Peru, K. E. Markham, Florencia Sangermano
Geography
Illegal, artisanal and small-scale gold mining (ASGM) often occurs in remote highly biodiverse areas, such as the Madre de Dios region of Peru. Mercury used in gold mining bioaccumulates in the environment and poses developmental, hormonal, and neurological threats to wildlife. The impact of ASGM on biodiversity remains largely unknown. We used geographic information science to create a spatial model of pollution risk from mining sites, in order to predict locations and species assemblages at risk. Multicriteria evaluation was used to determine how flow accumulation, distance from mining areas, total suspended sediment load, and soil porosity influenced the vulnerability of …

Understory vegetation and ground cover drive many important ecosystem processes, including tree seedling regeneration. The exact effect of ground cover on tree seedling establishment, survival, and growth depends on biophysical context. In subalpine forests, this context is largely determined by disturbances such as beetle outbreak, blowdown, and fire. Compounded disturbances that overlap in short succession can alter stand properties and trajectories in ways that are not predictable from the additive impact of individual disturbances. The aim of this study is to examine how compounded Dendroctonus rufipennis (spruce beetle; SB) outbreak followed by fire and compounded wind blowdown followed by fire …
