Trends in land degradation ( BBA )
This indicator is proposed as an indicator for Sustainable Development Target 15.3 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
** Trends in Land Cover/Land Use: (1) Global: e.g. http://www.glcn.org/databases/se_change_en.jsp, http://www.esa-landcovercci. org/ (2) Regional: e.g. http://www.eea.europa.eu/data-andmaps/ data/corine-land-cover ** Trends in Land Productivity: remote sensing data bases of NDVI and other Vegetation Indices/Variables, e.g. http://gcmd.gsfc.nasa.gov/index.html, http://land.copernicus.eu/global/themes/Vegetation, http://wad.jrc.ec.europa.eu/ ** Trends in Soil Organic Carbon: global spatial

The United Nations Convention to Combat Desertification (UNCCD) compiles data for this indicator. The necessary data are obtained primarily from remote sensing data acquired and processed by various international organizations. As part of the reporting and review process, national estimates derived from global datasets are validated by UNCCD country Parties or replaced with national estimates using data sourced/computed nationally/locally.
