UNCCD Terminology

Keywords

UNCED

The United Nations Conference on Environment and Development, also known as the Rio Earth Summit held in Rio de Janeiro in 1992. It promoted a new, integrated approach to the problem of desertification emphasizing action to promote sustainable development. It recommended that the United Nations General Assembly establish an Intergovernmental Negotiating Committee to prepare, by June 1994, a United Nations Convention to Combat Desertification.

Vector data

Glossary source
PRAIS

A representation of the world using points, lines and polygons. Vector models are useful for storing data that has discrete boundaries, such as country borders, land parcels and streets.

Vegetation Index

Glossary source
PRAIS

A mathematical combination or transformation of spectral bands that accentuates the spectral properties of green plants so that they appear distinct from other image features. Such as NDVI, EVI or FAPAR.

Venture philanthropy

Glossary source
PRAIS

A set of activities that includes collection, transport, treatment, and disposal of waste, prevention of waste production, and modification and reuse/ recycling of waste.

Vulnerability

Glossary source
PRAIS

Vulnerability refers to conditions determined by physical, social, economic and environmental factors or processes, which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards, such as drought. Hence, vulnerability is an inherent property of a system that exists independently of the external hazard, i.e. the same level of hazard may impose different consequences in different systems (communities, individuals, countries, regions) due to the distinct underlying vulnerabilities of the systems. In turn, vulnerability to the hazard and its impacts can be altered by the actions of society, such as land and water management practices, among others. For UNCCD reporting, three components of vulnerability are considered: social vulnerability, economic vulnerability and infrastructural vulnerability. See also ‘Drought Vulnerability Index (DVI)’

Waste (water) management

Glossary source
PRAIS

A set of activities that includes collection, transport, treatment, and disposal of waste, prevention of waste production, and modification and reuse/ recycling of waste.

Water bodies

Glossary source
PRAIS

For the purpose of UNCCD reporting, this land cover class includes any geographic area covered by inland water bodies with a water persistence of 12 months per year. In some cases the water can be frozen for part of the year (less than 10 months). This class refers to areas that are naturally or artificially covered by water, such as lakes and/or rivers. It includes areas that are covered by water due to the construction of artefacts such as reservoirs, canals, artificial lakes, etc. Without these, the area would not be covered by water. The class also includes coastal water bodies composed on the basis of geographical features in relation to the sea (lagoons and estuaries). Because the geographic extent of water bodies can change, boundaries must be set consistently with this class 7 according to the dominant situation during the year and/or across multiple years. It includes: i) Lakes, rivers and streams (natural/artificial, standing/flowing, inland/sea); ii) Artificial reservoirs; iii) Coastal lagoons; and iv) Estuaries.

Water harvesting

Glossary source
PRAIS

The collection and management of floodwater or rainwater run-off to increase water availability for domestic and agricultural use as well as ecosystem sustenance.

Watershed

Glossary source
PRAIS

A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. The word watershed is sometimes used interchangeably with drainage basin or catchment. Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water--lakes, streams, reservoirs, and wetlands--and all the underlying ground water

Wetland

Glossary source
PRAIS

For the purpose of UNCCD reporting, this land cover class includes any geographic areas that are transitional between pure terrestrial and aquatic systems, where the water table is usually at or near the surface or the land is covered by shallow water. The vegetative cover is significantly influenced by water and dependent on flooding (e.g. marshes, swamps and aquatic beds). The class includes any area dominated by trees, shrubs or herbaceous vegetation (cover of 10% or more) that is seasonally or permanently flooded with inland fresh water or by salt and/or brackish water located in the coastal areas or in the deltas of rivers. It includes coastal mangroves. Flooding must persist for at least 2 months per year to be considered regular (water persistence from 2 to 12 months per year). Occasionally-flooded vegetation within a terrestrial environment is not included in this class. It includes: i) Inland marshes, ii) Peat bogs, and iii) Intertidal flats.

Wetland protection / management

Glossary source
PRAIS

Managing wetland typically involves manipulating water levels and vegetation in the wetland, and providing an upland buffer.
