Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein
Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein
Jennifer Gebelein
The citrus industry has the second largest impact on Florida's economy, following tourism. Estimation of citrus area coverage and annual forecasts of Florida's citrus production are currently dependent on labor-intensive interpretation of aerial photographs. Remotely sensed data from satellites has been widely applied in agricultural yield estimation and cropland management. Satellite data can potentially be obtained throughout the year, making it especially suitable for the detection of land cover change in agriculture and ...

We describe results of a multi-year effort to strengthen consideration of the human dimension into endangered species risk assessments and to strengthen research capacity to understand biodiversity risk assessment in the context of coupled human-natural systems. A core group of social and biological scientists have worked with a network of more than 50 individuals from four countries to develop a conceptual framework illustrating how human-mediated processes influence biological systems and to develop tools to gather, translate, and incorporate these data into existing simulation models. A central theme of our research focused on (1) the difficulties often encountered in identifying and …

This paper focuses on the contribution that a combination of public domain GIS data with extensive habitat data can make to Khulan conservation in southern Mongolia. We describe a dataset taken in the Great Gobi 'A' Strictly Protected Area which represents the driest region within the overall Khulan distribution range. Potential habitats were classified following a phyto-sociological approach based on vegetation samples collected in the field. These data are combined with an open source climate model that allowed assessment of the influences of mean precipitation and temperature regime on habitat conditions. The results are put into a Gobi-wide context providing …

Large herbivore livestock and wildlife in Mongolia depend almost entirely for substance on forage standing crop produced each year on natural pastureland. Consequently, both livestock and wildlife are continuously subject to environmental risk, especially drought and severe winter storms, while livestock are also subject to financial risk. As consumption-based livestock production changes to commercialized livestock production, steps taken by the livestock herder to avert both environmental and financial risk to livestock can increase environmental risk to large wild herbivores. A realistic and workable pastureland and risk management system will be critical for conservation of large herbivore habitat. New technologies are …

In the future, grid mapping of animal and plant organisms will also play a major role in Mongolia. Based on geographical coordinates, a grid with a resolution of 100 x 100 km was created, which contained 561 cells. Methods and level of current understanding are exemplified by means of two raptors and three mammal species. This establishes a basis for an initial project, which will summarize all breeding occurrences of raptors based on all records, publications, or diary notes. For the first time, the short toed eagle was verified in Mongolia as a breeding bird in 2004. By 2006, ten …
