Land cover is the physical material at the land surface of Earth. Land covers include flora , concrete , built structures, bare ground, and temporary water . Earth cover is the expression used by ecologist Frederick Edward Clements that has its closest modern equivalent being vegetation .
Collective land use and land cover changes have fundamentally altered the functioning of key Earth systems. [16] For instance, human changes to land use and land cover have a profound impact climate at a local and regional level, which in turn contributes to climate change. [16]
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.
Land use, land-use change, and forestry (LULUCF), also referred to as Forestry and other land use (FOLU) or Agriculture, Forestry and Other Land Use (AFOLU), [3] [4]: 65 is defined as a "greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use such as settlements and ...
Percentage figures for arable land, permanent crops land and other lands are all taken from the CIA World Factbook [1] as well as total land area figures [2] (Note: the total area of a country is defined as the sum of total land area and total water area together.) All other figures, including total cultivated land area, are calculated on the ...
The cost of land use planning is usually high, generally because of poor investment and the lack of anticipation of technology. Land use planning theory has largely been shaped by case studies of cities in the Global North. Countries all over the world, particularly in the Global South, are seeing population booms and rapid urbanization.
Land is often defined as the solid, dry surface of Earth. [1] The word land may also collectively refer the collective natural resources of Earth, [2] including its land cover, rivers, shallow lakes, its biosphere, the lowest layer of the atmosphere (troposphere), groundwater reserves, and the physical results of human activity on land, such as architecture and agriculture.

CLUE (conversion of land use and its effects) model is a spatially explicit land-use change model developed to simulate future land-use and land-cover changes, including urban expansion, deforestation, land abandonment, and agricultural intensification.
