Cette table fournit des métadonnées pour l'indicateur réel disponible à partir des statistiques US les plus proches de l'indicateur SDG global correspondant. Veuillez noter que même lorsque l'indicateur global des ODD est entièrement disponible à partir des statistiques US, ce tableau devrait être consulté pour obtenir des informations sur la méthodologie nationale et d'autres informations sur les métadonnées spécifiques à un pays_adjectif.

Actual indicator available Percent of U.S waters in an MPA
Actual indicator available - description Percent of U.S. marine waters in a natural or cultural heritage marine protected area
Date of national source publication Fall 2017
Method of computation The indicator is computed by dividing the total number of KBAs wholly covered by protected areas by the total number of KBAs in each country, and multiplying by 100. 'Wholly protected' is defined as >98% coverage to allow for resolution and digitisation errors in the underlying spatial datasets.
Periodicity Annual, as needed
Scheduled update by national source Annual, as needed
U.S. method of computation Area coverage of all U.S. natural and cultural heritage MPAs relative to total area of U.S. marine waters Including bays, estauries and Great Lakes). Protected areas that include terrestrial areas are clipped to include only marine portion in area statistics.
Comments and limitations Based on national scale GIS-based area calculations (using the World Eckert IV projection, an equal-area pseudocylindrical map projection).

Nom de l'indicateur Coverage of protected areas in relation to marine areas
Nom de la cible By 2020, conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information.
Description de l'indicateur global Definition The percentage of marine sites contributing significantly to the global persistence of biodiversity that are wholly covered by designated protected areas. It is a thematic disaggregation of the multi-purpose indicator for protected area coverage of important sites. Concepts Protected areas, as defined by the International Union for Conservation of Nature (IUCN), are clearly defined geographical spaces, recognized, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values. Importantly, a variety of specific management objectives are recognised within this definition, spanning conservation, restoration, and sustainable use: Category Ia: Strict nature reserve Category Ib: Wilderness area Category II: National park Category III: Natural monument or feature Category IV: Habitat/species management area Category V: Protected landscape/seascape Category VI: Protected area with sustainable use of natural resources The status "designated" is attributed to a protected area when the corresponding authority, according to national legislation or common practice (e.g., by means of an executive decree or the like), officially endorses a document of designation. The designation must be made for the purpose of biodiversity conservation, not de facto protection arising because of some other activity (e.g., military). Sites contributing significantly to the global persistence of biodiversity are identified following globally standard criteria applied at national levels. Two variants of these standard criteria have been applied in all countries to date. The first is for the identification of Important Bird & Biodiversity Areas (IBAs), that is, sites contributing significantly to the global persistence of biodiversity, identified using data on birds, of which >12,000 sites in total have been identified from all of the world's countries. The second is for the identification of Alliance for Zero Extinction sites (AZEs), that is, sites holding effectively the entire population of at least one species assessed as Critically Endangered or Endangered on The IUCN Red List of Threatened Species. In total, 587 AZE sites have been identified for 920 species of mammals, birds, amphibians, reptiles, conifers, and reef-building corals. A global standard for the identification of key biodiversity areas (KBAs) unifying these approaches along with other mechanisms for identification of important sites for other species and ecosystems is in the final stages of development and anticipated to be in place by the end of 2015. Marine sites are defined as those identified for marine species or ecosystems, as documented in the IUCN Red List Habitats Classification Scheme.
