Spatio-Temporal Characteristics Of Mississippi Wildfires, Saranee Dutta
Theses and Dissertations
Based on wildfire data acquired from Mississippi forestry commission from 1991- 2005 approximately 4,000 wildfires occur in Mississippi each year, burning over 60,000 acres of forest and grassland. This study focuses on Mississippi’s wildfires from 1991- 2005 for the summer/fall period defined for this study as the May-November fire season. Statistical analysis indicates that there is significant correlation between vegetation indices derived from remotely sensed data and wildfire size at various time lag periods. Forest areas are correlated with vegetation indices at longer lag periods, nonorested areas are correlated at shorter lag periods. The inverse correlation between wildfire size and …
The Development And Use Of A Geographic Information System For Evaluating The Association Between Pesticide Exposure And Prostate Cancer, Kristen Wells
Theses and Dissertations
Abstract 1 – A Geographic Information System for Evaluating Residential Pesticide Exposure and Prostate Cancer Incidence Agricultural pesticide exposure is hypothesized to be a risk factor for prostate cancer, and such exposures are of particular concern for men living in farming communities where large-scale pesticide applications occur. Prostate cancer incidence data were obtained from the State Health Registry of Iowa for the years 1996 through 2006, and county and census tract level age-adjusted incidence rates were calculated. Historical crop-specific land use records and pesticide sales data for the state of Iowa during 1990 were integrated into a geographic information system …
