The more commonly used methods are land clearance, land reclamation and maximising land use.
Land clearance methods such as deforestation. Deforestation is the clearance of forests by methods such as logging and burning. Deforestation occurs for many reasons, such as trees are used as, or sold, for fuel or as a commodity, while the cleared land is used as pasture for livestock, plantations of commodities, and settlements. The removal of trees without sufficient replanting of trees will result in a lot of damage to nature. Deforested regions typically incur significant adverse soil erosion and oftenly degrade into wasteland.
Land reclamation methods such as landfill, reclaiming derelict land, empoldering and draining swamps.
Maximising land use such as urban land use(mixed land use) and agricultual land use (terracing, soil-less farming and irrigation).
