Regional studies of land cover change are often limited by available data and in terms of comparability across regions, by the transferability of methods. This research addresses the role of roads and infrastructure improvements across a tri-national

Savanna ecosystems are an important component of dryland regions and yet are exceedingly difficult to study using satellite imagery. Savannas are composed are varying amounts of trees, shrubs and grasses and typically traditional classification schem

Geospatial techniques, using Geographic Information Systems and remote sensing data, have become more commonly used with dasymetric modeling of fine-scale demographic data. In this study, we apply a dasymetric approach using the Heuristic Sampling Me

In the Amazonian rainforest, a new and pervasive spatial pattern has been created by road paving and the impacts of road paving usually extend from a small-scale region to an entire social–ecological system, making a multi-scale analysis imperative

Economic globalization manifests in landscapes through regional integration initiatives involving trans-boundary infrastructure. While the relationships of roads, accessibility and land cover are well-understood, they have rarely been considered acro

Tropical forests in the Amazon are being cleared rapidly, and road paving has stimulated this process and consequently prompted forest clearing. Fractal analysis can be used to study the spatial patterns of such developed areas, specifically by utili

New infrastructure reorganizes spaces by modifying connectivity among locations. We report findings pertaining to rural–urban connectivity in the southwestern Amazon, a tri-national frontier with varying levels of infrastructure due to recent highw

Prior studies of neighborhood crime have largely overlooked a border issue in the aggregation of criminal incidents to small areal units and a denominator problem arising from the use of population to normalize crime counts and have failed to discern

Information on post-hurricane urban forest debris in the Southeastern United States is limited. A stratified subset of permanent plots within the city of Houston, Texas, originally established in 2001 were selected and measured for hurricane impacts

We present evidence from the analysis of gridded annual rainfall data that, increased variability and declining rainfall totals are the main cause of declining lake levels in the Volta basin above the Akosombo Dam. West Africa has undergone a period
