In the absence of a federal geologic repository or consolidated, interim storage in the United States, commercial spent fuel will remain stranded at some 75 sites across the country. Currently, these include 18 “orphaned sites” where spent fuel has been left at decommissioned reactor sites. In this context, local communities living close to decommissioned nuclear power plants are increasingly [...]

Advances in sensing and computation have accelerated at unprecedented rates and scales, in turn creating new opportunities for natural resources managers to improve adaptive and predictive management practices by coupling large environmental datasets with machine learning (ML). Yet, to date, ML models often remain inaccessible to managers working outside of academic research. To identify [...]

A continental-scale assessment of density, size, distribution, and historical trends of Australian farm dams

Subjects: Environmental Monitoring, Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Physical Sciences and Mathematics, Water Resource Management

Australia is the second driest continent on Earth and freshwater is, therefore, a critical policy concern. Farm dams are ubiquitous and drive AU$17.7 billion of agricultural value, yet there has never been a formal census of Australian dams. In this study, we present a continental-scale assessment on density, distribution, and historical trends of farm dams in each State and Territory of [...]

Overview of recent land cover changes in the biodiversity hotspots

Biodiversity hotspots are the most biologically rich, yet threatened, terrestrial regions. From 1992 to 2015, they underwent 148 Mha of land cover changes, including forest losses (56 Mha, of which 40 Mha caused by agricultural expansion), declines of shrubland or savannah (23 Mha), and urbanization (10 Mha). The three largest losses in forest areas occurred in Sundaland, Indo-Burma, and [...]

Revealing day-to-day evolution of snowpack and snow drought conditions with phase diagrams

Benjamin Hatchett, Daniel McEvoy

Subjects: Earth Sciences, Environmental Sciences, Hydrology, Natural Resources Management and Policy, Physical Sciences and Mathematics

Snow droughts commonly are defined as below average snowpack at a point in time, typically 1 April. This definition is valuable for interpreting the state of the snowpack for resource management but obscures the temporal evolution of snow drought. Borrowing from dynamical systems theory, we applied phase diagrams to visually examine the evolution of ephemeral snowpack conditions in maritime, [...]

Range-based intensity normalization of ALS data over forested areas using a sensor tracking method from multiple returns

Airborne laser scanning (ALS) point-clouds are used in forest inventory to map properties of the resource. In most cases, only the (x,y,z) coordinates of the point cloud are used to build predictive models of forest structure. Despite being recorded and provided by data suppliers, the intensity values associated with each point are rarely used as an input to such models because raw intensity [...]

Evaluating single and multi-date Landsat classifications of land-cover in a seasonally dry tropical forest

Accurate information on the land cover is crucial for efficient monitoring and development of environmental studies in the Brazilian Caatinga forest. It is the largest tropical seasonal forest in South America, presenting high biodiversity and is under intense anthropogenic disturbance. Caatingas land cover is heterogeneous, and rainfall is its primary phenological regulator, presenting mainly [...]

Feedback between drought and deforestation in the Amazon

Deforestation and drought are among the greatest environmental pressures on the Amazon rainforest, possibly destabilizing the forest-climate system. Deforestation in the Amazon reduces rainfall regionally, while this deforestation itself has been reported to be facilitated by droughts. Here we quantify the interactions between drought and deforestation spatially across the Amazon during the early [...]

The Sweepstakes in Fathom Five National Marine Park is one of Ontarios more iconic shipwrecks. Continued exposure to water currents has directly and indirectly affected the integrity of the wreck and resulted in management interventions including efforts to stabilize the wreck and control vessel activity. An extensive series of field measurements were made during the peak tourist season in the [...]

The increasing impact of flooding urges more effective flood management strategies to guarantee sustainable ecosystem development. Recent catastrophes underline the importance of avoiding local flood management, but characterizing large scale basin wide approaches for systemic flood risk management. Here we introduce an information-theoretic Portfolio Decision Model (iPDM) for the optimization of [...]

Recent decades have seen a considerable increase in shrimp aquaculture in tropical and subtropical developing countries. This practice is controversial due to its potential for serious economic, food security, and environmental impacts. Of particular concern is the widespread practice of intensive aquaculture in and near mangrove ecosystems where many shrimp species spawn. However, while [...]
