Indicador 6.6.1: Cambio en la extensión de los ecosistemas relacionados con el agua con el paso del tiempo

Change in the extent of water-related ecosystems over time

Esta tabla proporciona metadatos para el indicador real disponible a partir de las estadísticas de US más cercanas al correspondiente indicador global de SDG. Tenga en cuenta que incluso cuando el indicador global de ODS esté totalmente disponible a partir de las estadísticas de US, se debe consultar esta tabla para obtener información sobre la metodología nacional y otra información de metadatos específicos de US.

Date of national source publication
Method of computation 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).

Nombre del indicador Change in the extent of water-related ecosystems over time
Nombre de destino By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes.
Descripción del indicador global 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.
