| 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). |
