      <p>Figures for tree cover extent, loss, and gain presented on the country and global overview pages were calculated using tabular data from a 2013 publication, “<a href='http://www.sciencemag.org/content/342/6160/850' target='_blank'>High-Resolution Global Maps of 21st-Century Forest Cover Change</a>" by Hansen <em>et al</em>.</p>

      <h3 class='overview_title'>European Space Agency (GlobCover)</h3>
      <p>Data from the European Space Agency’s GlobCover was used to visualize tree cover extent on the country profiles. As stated on the <a href='http://due.esrin.esa.int/globcover/' target='_blank'>ESA website</a>, GlobCover is an initiative which began in 2005 in partnership with a number of organizations. The aim of the project was to develop a service capable of delivering global composites and land cover maps using input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. ESA makes available the land cover maps, which cover 2 periods: December 2004 - June 2006 and January - December 2009. To learn more, visit the <a href='http://due.esrin.esa.int/globcover/' target='_blank'>GlobCover website</a> or <a href='http://due.esrin.esa.int/globcover/LandCover2009/Globcover2009_V2.3_Global_.zip' target='_blank'>download the 2009 GlobCover map</a>.</p>

      <h3 class='overview_title'>The Rights and Resources Initiative (RRI)</h3>
      <p>Figures on forest tenure come from the Rights and Resource Initiative and are based on data adapted from the <a href='http://www.rightsandresources.org/documents/index.php?pubID=1075' target='_blank'>Tropical Forest Tenure Assessment</a>. The goal of the report is to present and analyze the state of forest tenure in much of the world’s tropical forests. As stated on <a href='http://www.rightsandresources.org/programs.php?id=237' target='_blank'>RRI's website</a>, the tenure systems represented by this data is sourced from governments, and therefore only reflects those systems of natural resource management that are legally recognized by those governments. Such officially outlined tenure systems fall under the category of statutory tenure regimes within these studies. The official data often presents an incomplete picture of the institutions that actually manage natural resources, particularly at a local level.

negative.code:           <p>These infographics were created using tree cover, loss, and gain data from the University of Maryland (UMD)/Google. For more information on this data set, please visit the <a href="/sources/forest_change?t=umd_tree_loss_gain" target="_blank">data page</a>. </p>
  
            <p>The UMD/Google infographics can be viewed by country or by subnational boundary. Click "Select Jurisdiction" to view data for a different region.</p>
            
            <p>Due to variation in research methodology and/or date of content, tree cover and tree cover loss and gain statistics cannot be compared against each other. Accordingly, “net” loss cannot be calculated by subtracting tree cover gain from tree cover loss, and current (or post-2000) tree cover cannot be determined by subtracting annual tree cover loss from year 2000 tree cover. </p>
            
            <p>Please also be aware that “tree cover” does not equate to “forest cover.” “Tree cover” refers to the biophysical presence of trees, which may be a part of natural forests or tree plantations. Thus, loss of tree cover may occur for many reasons, including deforestation, fire, and logging within the course of sustainable forestry operations. Similarly, tree cover gain may indicate the growth of tree canopy within natural or managed forests.</p>
  
            <p><strong>Note</strong>: "Select Jurisdiction" and "Tree Cover Canopy Settings" only affect infographics within the UMD/Google data portion of the country profiles and do not apply to FORMA, Forest Type, People & Economy" or to other parts of this page. </p>
