"},"editorialNote":{"en":["source:IPCC Glossary AR6","source:UNDRR HIPS"]},"scopeNote":{"en":["Drought is described as conditions that are significantly drier than normal or otherwise limiting moisture availability to a potentially damaging extent (WMO and GWP, 2016) or as conditions where there had been a prolonged absence or marked deficiency of precipitation (WMO/UNESCO, 2012). Whereas drought may be defined simply as the absence of water, it is a complex phenomenon which is monitored over a number of time scales and often defined according to need. It is a slow-onset phenomenon that gradually intensifies and can impact many sectors of the economy and the environment (Drought Observatory, no date). Droughts can be characterised in terms of their severity, location, duration and timing. Droughts can arise from a range of hydrometeorological processes that supress precipitation and/or limit surface water or groundwater availability. There are various drought indicators and indices that provide options for identifying the severity, location, duration onset and cessation of such conditions. It is important to note that the impacts of drought can be as varied as the causes of drought. Droughts can adversely affect agriculture and food security, hydropower generation and industry, human and animal health, livelihood security, and personal security and access to education. Such impacts depend on the socio-economic contexts in which droughts occur, in terms of who or what is exposed to the droughts and the specific vulnerabilities of the exposed entities (WMO and GWP, 2016). The drought community has defined several different types of drought that have can general or specific sector impacts (NOAA, no date b):"]},"narrower":[{"id":"http://connectivity-hub.com/terms/3df9efa9-57da-46f2-b4d7-20c13dc10d80","prefLabel":{"en":"Agricultural and ecological drought"}},{"id":"http://connectivity-hub.com/terms/0913ea1e-64c5-465c-a6c4-453efe74fb1a","prefLabel":{"en":"Hydrological drought"}},{"id":"http://connectivity-hub.com/terms/d30affd8-1f9c-4873-ad0b-68dad92dba05","prefLabel":{"en":"Megadrought"}},{"id":"http://connectivity-hub.com/terms/41f4596d-a052-49c0-828f-76973ad8a6de","prefLabel":{"en":"Meteorological drought"}}],"broader":{"id":"http://connectivity-hub.com/terms/9f092fb6-576c-4250-9347-42a3e8cd7358","prefLabel":{"en":"Precipitation Related"}},"inScheme":[{"id":"http://connectivity-hub.com/terms/","title":{"en":"Climate Connectivity Taxonomy"}}],"inSchemeAll":[{"id":"http://connectivity-hub.com/terms/"}],"@context":{"@version":1.1,"id":"@id","type":"@type","@vocab":"http://www.w3.org/2004/02/skos/core#","xsd":"http://www.w3.org/2001/XMLSchema#","dct":"http://purl.org/dc/terms/","dc":"http://purl.org/dc/elements/1.1/","schema":"https://schema.org/","vann":"http://purl.org/vocab/vann/","ldp":"http://www.w3.org/ns/ldp#","owl":"http://www.w3.org/2002/07/owl#","title":{"@id":"dct:title","@container":"@language"},"dc:title":{"@id":"dc:title","@container":"@language"},"dc:description":{"@id":"dc:description","@container":"@language"},"description":{"@id":"dct:description","@container":"@language"},"license":{"@id":"dct:license","@container":"@language"},"issued":{"@id":"dct:issued","@type":"xsd:date"},"created":{"@id":"dct:created","@type":"xsd:date"},"modified":{"@id":"dct:modified","@type":"xsd:date"},"creator":"dct:creator","publisher":"dct:publisher","preferredNamespacePrefix":"vann:preferredNamespacePrefix","preferredNamespaceUri":"vann:preferredNamespaceUri","isBasedOn":"schema:isBasedOn","source":"dct:source","prefLabel":{"@container":"@language"},"altLabel":{"@container":["@language","@set"]},"hiddenLabel":{"@container":["@language","@set"]},"definition":{"@container":"@language"},"note":{"@container":["@language","@set"]},"changeNote":{"@container":["@language","@set"]},"editorialNote":{"@container":["@language","@set"]},"historyNote":{"@container":["@language","@set"]},"scopeNote":{"@container":["@language","@set"]},"notation":{"@container":"@set"},"example":{"@container":"@language"},"narrower":{"@container":"@set"},"related":{"@container":"@set"},"relatedMatch":{"@container":"@set"},"narrowerTransitive":{"@container":"@set"},"broaderTransitive":{"@container":"@set"},"broadMatch":{"@container":"@set"},"narrowMatch":{"@container":"@set"},"closeMatch":{"@container":"@set"},"exactMatch":{"@container":"@set"},"hasTopConcept":{"@container":"@set"},"inScheme":{"@container":"@set"},"topConceptOf":{"@container":"@set"},"deprecated":{"@id":"owl:deprecated","@type":"xsd:boolean"},"isReplacedBy":{"@id":"dct:isReplacedBy","@container":"@set"}}}
