This table provides metadata for the actual indicator available from Turkey statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Turkey statistics, this table should be consulted for information on national methodology and other Turkey-specific metadata information.
| Target name | By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world |
|---|---|
| Indicator name | Proportion of land that is degraded over total land area |
| Global / Proxy indicator | Global indicator |
| Description of indicator | Land degradation is defined as the reduction or loss of the biological or economic productivity and complexity of rain fed cropland, irrigated cropland, or range, pasture, forest and woodlands. This indicator expresses the proportion (%) of land that is degraded over total land area between 2000-2015. Data is calculated by excluding the area covered by inland waters, like major rivers and lakes from total land area, compatible with global metadata. |

| Calculation |
Sustainable Development Goal (SDG) Indicator 15.3.1: ratio of degraded land to total land area, three sub-indicators of land degradation: 1. Trends in land cover 2. Trends in land productivity dynamics 3. Trends in carbon stocks (underground and aboveground) calculated with indicators. It is calculated by integrating the sub-indicators using the all-in-one (10AO) (one-out-all-out) method, where a significant decrease or negative change in any of the three sub-indicators is considered to constitute land degradation ((https://www.unccd.int/ Sites/default/files/relevant-links/2021-03/Indicator_15.3.1_GPG_v2_29Mar_Advanced-version.pdf) Significant reductions can be identified using statistical criteria or by a qualitative assessment of the magnitude of change. The measurement is reported as (degraded/unspoiled) and expressed as the ratio (percentage) of degraded land to the total land area. (Degraded land area / Total land area) * 100 |
| Comparability | Produced in full compliance with global metadata |
| Revision | The previously reported 2015 SDG 15.3.1 was revised due to the use of national maps and classes and a model change in the representation of sub-indicators. Values for 2019 were calculated using the same method. The data (percentage) will be updated with the same methodology in the reporting made/to be made every four years. |
| Other information | The related deterioration is calculated over the three indicators evaluated within the scope of Land Degradation Offset (LDA). These indicators are soil organic carbon, land cover and land cover change, and land productivity. If only one of these three indicators is evaluated as negative on a per pixel basis, this area is considered as a degraded area. |
