En la investigación internacional se estimó la extensión de los bosques en tierras secas. Contó con la participación de 31 científicos, entre los que se encuentra Elena Abraham, investigadora de CONICET y directora académica del Observatorio Nacional de la Degradación de Tierras y Desertificación (ONDTyD).

  • Abstract
Dryland biomes cover two-fifths of Earth’s land surface, but their forest area is poorly known. Here, we report an estimate of global forest extent in dryland biomes, based on analyzing more than 210,000 0.5-hectare sample plots through a photo-interpretation approach using large databases of satellite imagery at (i) very high spatial resolution and (ii) very high temporal resolution, which are available through the Google Earth platform. We show that in 2015, 1327 million hectares of drylands had more than 10% tree-cover, and 1079 million hectares comprised forest. Our estimate is 40 to 47% higher than previous estimates, corresponding to 467 million hectares of forest that have never been reported before. This increases current estimates of global forest cover by at least 9%.
