What does LULCC stand for? |
Land Use and Land Cover Change |
|
What is the difference between Land Cover and Land Use Change? |
Land Cover - the physical and biological cover over the surface of land, including water, vegetation, bare soil, and/or artificial structures. Land Use - related to human activities such as agriculture, forestry and urban construction that alter land surface processes including biogeochemistry, hydrology and biodiversity. |
|
How do changes in land cover affect the global carbon cycle? |
Disturbance to soils and removal of vegetation during deforestation. Tillage disturbs surface and releases soil carbon. |
|
What are some common LULCC process that can be observed by remote sensing? |
Desertification - persistent degradation of dryland ecosystems by human activity and/or climate change Tropical Deforestation Fire Food production - agriculture and ranching Urbanization |
|
How is desertification most commonly monitored using remote sensing? |
NDVI (Normalized Difference Vegetation Index) |
|
What are the earliest observations of deforestation from remote sensing? |
1972 |
|
How does the urban heat island effect change based on surrounding vegetation? |
Larger the city = stronger the heat island.Cities located in forested regions have stronger heat islands than cities in grassy or desert environments. |
