This table provides metadata for the actual indicator available from Moldovan statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available, this table should be consulted for information on national methodology and other Moldovan-specific metadata information.

Indicator 6.6.1: Surface change dynamics of water-related ecosystems (indicators on the spatial extent of water-related ecosystems, water quality of lakes and artificial water bodies, the amount (discharge) of water in rivers and estuaries, the quality of water-related ecosystems, the amount of groundwater in aquifers) |

| Definition and concepts |
The indicator includes five categories: 1) wetlands with vegetation, 2) rivers and creeks, 3) lakes, 4) aquifer 5) artificial water bodies. The indicator is divided in 5 sub-indicators for capturing different sources of data and methodologies, which are necessary for monitoring the components of the indicator. The data sources derive from a combination of soils samples and observations regarding the soil. Depending on the type of ecosystem and type of measured degree, the methodology for collecting data may differ a lot. The 5 sub-indicators are calculated separately according to 5 different methodologies: Sub-indicator 1: Spatial extension of water-related ecosystems; Sub-indicator 2: Quality of lakes and artificial water bodies; Sub-indicator 3: Quantity (discharge) of water in rivers and creeks; Sub-indicator 4: Quality of water-related ecosystems; Sub-indicator 5: Quantity of underground water from aquifers. Sub-indicators 1 and 2: All the data available at the global level, generated for these sub-indicators, are shared with countries for validation. These geospatial data will be generated annually at the national, subnational and water levels. While these data are generated annually, the measurement for verifying the changes needs to be carried out once per 5 years. The annual validated data will be used by specialised agencies to generate percentage changes on behalf of the countries. Sub-indicators 3, 4 and 5: All the data collected in countries for these sub-indicators will be sent to specialised agencies for verification and control for quality assurance, in line with the minimum criteria of the methodology. This analysis process will be facilitated through communication via email through the global assistance service. After analysis of annual „raw” data, the calculation of percentage changes will be finished and validated between the specialised agencies and the national representative. |
