1. A particular manner of using land, such as for residences or recreation.

2. A term used to describe the various ways in which human beings make use of the land and its resources, including farming, mining, building, or grazing sheep and cattle.

3. Involves both the manner in which the biophysical attributes of the land are manipulated and the intent underlying that manipulation.

4. Man's activities on land of which settlements, forestry, agriculture, mining, grazing and water use are the most predominant

5. Man's activities on land which are directly related to land. (Anderson et al. 1976).

6. Specific use or management-related activity, rather than the vegetation or cover of the land. The categories of and use are cropland, developed water resource, fish and wildlife habitat, forestry, industrial/commercial, pastureland (or land occasionally cut for hay), recreation, residential, and undeveloped land.

7. The arrangements, activities and inputs people undertake in a certain land cover type to produce, change or maintain it (Di Gregorio and Jansen 1997, 1998, Jansen and Di Gregorio 1998). A given land use may take place on one, or more than one, piece of land and several land uses may occur on the same piece of land. Definition of land use in this way provides a basis for precise and quantitative economic and environmental impact analysis and permits precise distinctions between land uses, if required. Lands may be devoid of forest cover, but may be used for forestry purposes. Similarly, lands may have tree cover, but not used for forestry use - i.e. "urban forests."

8. The documentation of human uses of the landscape: residential, commercial, agricultural, etc. Land use can be inferred but not explicitly derived from satellite and aerial imagery. There is no spectral basis for land use determination in satellite imagery.

9. The employment of a site or holding so as to derive revenue or other benefits from it; the delineation by a governing authority of the utilization of the land within a particular jurisdiction so as to promote the most advantageous development of the community such as industrial, residential, commercial, recreational and other uses under a plan. (HUDCC).

10. The human activity that is associated with a specific land unit, in terms of utilization, impacts or management practices (Thompson 1996).

11. The human employment of the land (Meyer and Turner 1992).

12. The intent and management strategy placed on a land cover type (Turner, et al. 1995).

13. The nature of the Earth's surface in areas where the human imprint upon land is dominant.

14. The predominant purpose for which an area is employed (USDA Forest Service 1989).

15. The purpose for which a specific land area is used by people; the socio-economic function of such an area. (Kalnensky et al. 2002).

16. The purpose of human activity on the land; it is usually, but not always, related to land cover. and

17. The purpose to which land is put by humans (e.g., protected areas, forestry for timber products, plantations, row-crop agriculture, pastures, or human settlements) (Turner and Meyer 1994). Change in land use may or may not cause a significant change in land cover. For example, change from selectively harvested forest to protected forest will not cause much discernible cover change in the short term, but change to cultivated land will cause a large change in cover.

18. The social and economic purposes for which land is managed (e.g., grazing, timber extraction,conservation). and

19. The socio-economic description (functional dimension) of areas: areas used for residential, industrial or commercial purposes, for farming or forestry, for recreational or conservation purposes, etc. Links with land cover are possible; it may be possible to infer land use from land cover and conversely. But situations are often complicated and the link is not so evident. Contrary to land cover, land use is difficult to "observe". For example, it is often difficult to decide if grasslands are used or not for agricultural purposes. Distinctions between land use and land cover and their definition have impacts on the development of classification systems, data collection and information systems in general.

20. The total of arrangements, activities, and inputs undertaken in a certain land cover type (a set of human actions). and

21. The type of human activity taking place at or near the earth's surface. (Cihlar and Jansen 2001).

22. The way in which, and the purposes for which, humans employ the land and its resources (Meyer 1995).

23. The way land is developed and used in terms of the kinds of activities allowed (agriculture, residences, industries, etc.) and the size of buildings and structures permitted.
