Recovering a Black Cemetery
Estimates suggest that over 15,000 people are buried at East End Cemetery, a historic African American cemetery in Richmond, Virginia, that until recently received no public funding for upkeep. Here, we present a case study analysis and potentially replicable methodology for counting and locating unmarked burial depressions in non-forested areas using a low-cost sUAV (drone) and simple, hydrology-based geographic information systems analyses. Upo…
Precipitation Drivers of Cropping Frequency in the Brazilian Cerrado
The Amazon basin has been subjected to unprecedented rates of land-use change over the past several decades, primarily as a result of the expansion of agriculture. Enhanced rain forest conservation efforts toward the end of the twentieth century slowed deforestation of the Amazon but, in turn, increased demand for land repurposing in the adjacent Cerrado (savanna) region, where conservation regulations are less strict. To maintain or increase yie…
Recent cropping frequency, expansion, and abandonment in Mato Grosso, Brazil had selective land characteristics
This letter uses satellite remote sensing to examine patterns of cropland expansion, cropland abandonment, and changing cropping frequency in Mato Grosso, Brazil from 2001 to 2011. During this period, Mato Grosso emerged as a globally important center of agricultural production. In 2001, 3.3 million hectares of mechanized agriculture were cultivated in Mato Grosso, of which 500 000 hectares had two commercial crops per growing season (double crop…
