Monitoring rozšiřování plantáží palmy olejné v Nikaragui pomocí metod dálkového průzkumu Země
Mezihoráková, Tereza
The first part of this bachelor's thesis is literature research that discusses the expansion of oil palm plantations in Central America, as well as remote sensing and monitoring of forest and agricultural areas using its methods. The practical part deals with the monitoring of oil palm plantations between 2017 and 2022 using satellite data. The analysed area was the Kukra Hill region located in the state of Nicaragua. PlanetScope multispectral images were used for the analysis. First, vegetation indices were calculated, classifications were made, the areas of plantations in the given years were determined and their comparison was made. In 2017, the area of oil palm plantations within the area of interest was 4,109 ha, but of this area, 445 ha disappeared by 2022, so 3,664 ha were preserved from 2017 to 2022. In 2022, the area of plantations was already 8,512 ha, which means that the area of oil palm plantations increased by 4,848 ha between the given years. The used methodology can also be used in other areas with similar geographical conditions, where oil palm plantations are expanding and will contribute to better monitoring of the studied phenomenon.
