Brazil is quickly becoming an influential actor on the world stage of geopolitics. The nation has achieved global economic and environmental recognition due to the extensive development of its hydrological resources in the form of hydroelectric power plants. As the world’s second greatest generator of hydroelectricity, Brazil has proven a staunch adherence to building dams in the large-scale. Though these dams have brought electricity to millions of people across the country, the socio-ecological toll inflicted by their construction has been devastating to natural biomes and local inhabitants. This article traces Brazil’s proclivity for large-scale hydropower to four motivational categories often …

Understanding the cross-scale linkages between drought and food security is vital to developing tools to reduce drought impacts and support decision making. This study reviews how drought hazards transfer to food insecurity through changes in physical processes and socio-environmental systems across a wide range of spatial and temporal scales. We propose a multi-scale, integrated framework leveraging modeling advances (e.g. drought and crop monitoring, water-food-energy nexus, decision making) and increased data availability (e.g. satellite remote sensing, food trade) through the lens of the coupled human–natural system to support multidisciplinary approaches and avoid potential policy spillover effects. We discuss current scale-dependent challenges …

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 …
