Exposure to drought

The dataset provides annual anomalies in land and cropland soil moisture content of the top soil layer compared to the reference period 1981-2010. Exposure indicators to drought have been prepared by the Organisation for Economic Co-operation and Development (OECD). Please see the <a href="https://doi.org/10.1787/da074cb6-en">working paper</a> for a more complete description of the methods.<br><br>The datasets span the period 1981-2022 and is the result of the use of a variety of geospatial data sources, including the ERA5-Land averaged monthly data of volumetric soil moisture and ESA CCI land cover data. Average anomalies have been calculated for both land and cropland exposure to drought. The dataset has a global coverage on a national level; on the sub-national TL2 level (i.e. large subnational regions) results are reported for all OECD countries as well as for Argentina, Brazil, China, India, Indonesia and South Africa. A number of aggregates are included: Euro area, European Union, Advanced economies, Emerging market economies, G7, G20, OECD, OECD Europe, OECD Asia Oceania, OECD Americas and the LAC region.<br><br><b>Data source(s)</b>: <a href="https://www.esa-landcover-cci.org/">Copernicus Climate Change Initiative</a> land cover data and <a href="https://cds.climate.copernicus.eu/#!/home">Copernicus Climate Data Store</a> monthly soil moisture data (ERA5).<br><br><b>Contact</b>: <a href="ENV.Stat@oecd.org">ENV.Stat@oecd.org</a><br><br>Database documentation
