Esta tabla proporciona información sobre los metadatos para los indicadores SDG definidos por el UNSC. Completa 6es proporcionada por la División de Estadística de las Naciones Unidas.
| SDG Indicator Name | Change in the extent of water-related ecosystems over time |
|---|---|
| SDG Target Addressed | By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes. |
| Definition of SDG Indicator | Percentage of change in water-related ecosystems over time (% change/year). The indicator would track changes over time in the extent of wetlands, forests and drylands, and in the minimum flows of rivers, volumes of freshwater in lakes and dams, and the groundwater table. The Ramsar Convention broad definition of "wetland" is used, which includes rivers and lakes, enabling three of the biome types mentioned in the target to be assessed - wetlands, rivers, lakes - plus other wetland types. |
| UN Designated Tier | 3 |
| UN Custodial Agency | UNEP (Partnering Agencies: UN-Water, IUCN, Ramsar) |

This table provides metadata for the actual indicator available from U.S. statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from U.S. statistics, this table should be consulted for information on national methodology and other US-specific metadata information
| Method of computation for global SDG indicator | It is proposed to estimate percentage change in each major ecosystem present in a country, and the indicator will enable Member States to report on those water-related ecosystems that are important to them. Wetland extent is computed through the existing Living Planet Index methodology for data collection and analysis (http://www.livingplanetindex.org/home/index). It consists of a number of stages including harvesting of time series data, codification and database entry, aggregation into sub-indices to reduce sampling bias, and further aggregation to create subglobal (ecologically and regionally specific) and global indices. The methodology is flexible to incorporating improving sources of information and data, for a more comprehensive assessment of trends. The structure of the indicator can be designed to align with the SEEA Water accounts and estimate percentage change in Natural Water Capital available to society based on a) Mean Annual Water Availability; b) Mean Annual Water Withdrawals; c) Environmental Water requirements Aquastat (FAO); GEMS Water for national data (UNEP). |
