Agenda 21	A term now commonly used to refer to all sustainability issues, it derives from the UN Conference on Environment and Development (the "Earth Summit") held in Rio in 1992, where the 21st item to be discussed was a set of guidelines, based around 27 basic principles, to assist countries in developing frameworks and approaches to sustainable development. Since it was designed to be applicable to countries throughout the world, the Agenda 21 document is inevitably very broad in its coverage, and is commonly 'customised' to suit a country or region's particular circumstances, giving rise to the sub-term "Local Agenda 21".
Aggregation	The process of dealing with the different landscape elements in a given area in a combined manner, resulting in a landscape character area or landscape character type.
Attribute	The specific types of landscape feature into which landscape parameters (see below) are broken down for the purposes of GIS mapping. For example, the landscape parameter 'Vegetation', may contain numerous attributes, including e.g. 'secondary woodland','fung shui woodland','scrub','grassland', etc.
Badlands	Landscapes formed where the chemical weathering of soils forms soils which are subsequently deeply eroded by rain. This results in a series of ridges and gullies of bare earth and rock.
Coastal Landscape	Landscapes which immediately adjoin the sea and whose character is therefore significantly influenced by the proximity of the sea.
Dis-aggregation	The process of dealing with different landscape elements in a given area as separate elements rather than as a landscape character area or landscape character type.
Elements	Individual components which make up the landscape (e.g. soils, woodland, roads, buildings)
Features	Particularly prominent or eye-catching elements in the landscape.
Footpath	Thoroughfare not wide enough for vehicles.
Gei wai	Intertidal pools and bunds formed in coastal areas for the harvesting of shrimp, fish, oysters, algae and sedges.
Highway	Public highway with two or more lanes.
Landscape	The aggregate effect on an observer, produced by the natural and man-made features on land. It is defined by natural features (such as geology, soils, hydrologic features and vegetation); by human features (such as land-use, buildings, roads, etc) and by its cultural associations.
Landscape Appraisal	The process of appraising a particular landscape, landscape type or landscape feature, by reference to specified criteria.
Landscape Assessment	A general term for the process whereby landscape is described, classified and evaluated.
Landscape Character	A distinct pattern or combination of elements that occurs consistently in a particular landscape.
Landscape Character Area	The individual geographic areas in which there may be a number of LCTs, combining to create a distinctive pattern. They may share the characteristics of other areas of similar type but have their own particular identity. LCAs may be defined at a strategic or broad level (SLCAs) or at a detailed or local level (LLCAs).
Landscape Character Type	Generic areas of landscape which have a broadly similar patterns of landform, vegetation, land use and urban settlement in every area where they occur.
Landscape Character Unit	The smallest individual geographic unit with its own distinctive landscape character: a specific geographic manifestation of an LCT.
Landscape Classification	The process whereby the landscape is sorted into different types or units each with a distinct, consistent and recognisable character.
Landscape Condition	The index of the integrity or intactness of the basic pattern of landscape features, which constitute the landscape character of that type.
Landscape Description	The process of collecting and presenting information about the landscape in a systematic manner.
Landscape Evaluation	The process of attaching a value to a particular landscape, landscape type or landscape feature, by reference to specified criteria.
Landscape Sensitivity	Tolerance of change. Sensitivity is not absolute, but varies according to the type of landscape being considered.
Landscape Quality	The condition of landscape. Its state of repair or integrity.
Landscape Value	The reasons why a landscape is considered to be important.
Lane	Single land public highway.
Mangrove	a specific coastal plant community found on areas of inter-tidal mud.
Marine Landscapes	Areas of sea visible from the land, containing few or no terrestrial elements.
Nullah	an artificial water course or stream or river canalised for the purposes of drainage.
Maritime Landscape	The terrestrial landscape (see above) of the coast next to the sea, but also including the area of adjacent sea. It also includes offshore islands and island groups.
Parameter	A feature of landscape, which (amongst others) acts as a fundamental influence on its character and which is mapped and considered during the process of landscape classification (e.g. soil, topography, vegetation)
Resources	See 'Elements' above.
River	A natural water course where the water body is greater than 10m in width.
Rural Landscape	Landscapes which contain an extremely low level of built development. They may be 'natural' in the sense that they exhibit very low levels of human interference or may be agricultural.
Rural Fringe Landscape	Landscapes which overwhelmingly retain their rural characteristics together with a very low ratio of built to un-built space. At the same time, they are subject to change in traditional rural land use and low levels of non-intensive development or urbanisation (such as abandoned agricultural land, golf courses, highways development or storage yards)
Stream	A natural water course where the water body is less than 10m in width.
Track	Thoroughfare not wide enough for one vehicle - usually un-surfaced and not a public highway.
Urban Landscape	The aggregate effect on an observer, produced by the natural and man-made features in a built-up area. It is defined to certain extent by natural features (such as topography and vegetation) but often to a greater extent by human features (such as buildings, roads, etc) and by its cultural associations.
Urban Fringe Landscape	Landscapes on the edges of towns or cities characterised by lower densities and land uses requiring greater space; a more or less equal relationship between built and un-built spaces.
