LaFevor, M. 2012. Sulphur Mining on Mexico’s Popocatépetl Volcano (1820-1920): Origins, Development, and Human- Environmental Challenges. Journal of Latin American Geography. 11(1): 79-98.
This paper traces the origins and development of a little-known extractive industry in nineteenth-century Mexico: volcanic sulphur mining. Unpublished documents from Mexican archives, nineteenth-century travel literature, reports from early scientific expeditions, and historical newspapers provide the bulk of data. Documents show how both Mexican and United States interests – indigenous sulphur miners (azufreros) and venture capitalists – confronted the challenges of mining sulphur from the crater of Mexico’s Popocatépetl volcano, at 5,426 meters (17,802 feet) elevation.
The discovery, extraction, and monopolistic control of key natural resources was a priority of New Spain’s colonial administration. Managing the region’s abundant resources, however, often proved difficult for the Spanish Crown. Human and environmental challenges impeded protoindustrial growth and development, and monopolistic control of resources often met resistance. In this article I examine these processes in the context of New Spain’s little-known monopoly on sulphur—a yellow, powdery mineral the Crown jealously guarded as its own.
Mishra, N. B., Crews, K. A., & Neuenschwander, A. L. (2012).Sensitivity of EVI-based harmonic regression to temporal resolution in the lower Okavango Delta. International Journal of Remote Sensing. 33(24), 7703–7726.
In this study, we examined how satellite time-series-based characterization of ecological cycles and trends is sensitive to the temporal depth and spacing of the time series and whether the observed sensitivities were cover and/or cycle specific. The results show that as the temporal depth decreases, the sensitivity to both short- and long-term ecological cycles was lost in the seasonally dynamic environment.
