BEIJING, Nov. 20 (Xinhua) -- China has achieved a 30-meter-resolution Global Forest Cover Map (GFCM) of 2018 for forest management, according to the Aerospace Information Research Institute of the Chinese Academy of Sciences on Wednesday. The researchers constructed a high-resolution forest and ...
(2016). They compared design-based estimates of AGB in the miombo woodlands using airborne lidar, interferometric synthetic aperture radar (InSAR) derived from TanDEM-X, RapidEye optical imagery, and global map products of tree cover constructed from Landsat and forest/non-forest constructed from ...
Forest clearances have been responsible for multiple epidemics of leishmaniasis, Chagas disease and trypanosomiasis due to logging, road construction, fires and new human settlements. By influencing land cultivation and vegetation type and cover, new agricultural production dynamics shift vector-animal ...
forest loss has historically been a major source of greenhouse gas emissions, accounting for an estimated 47% of all emissions since 1750 (Le Quéré et al.2015). Deforestation
As the oceans’ heat capacity is about a thousand times greater than that of the atmosphere, they play a significant role in controlling the global climate (Barange and Perry2009). Globally, the sea level has risen by 10-20 cm during the 20th century, primarily because of thermal expansion...
Some authors have overcome this by using Open Street Map annotations to confirm water presence for model training (Mazhar et al., 2022) but along with using water presence maps (Pekel et al., 2016) these methods cannot be used with PlanetScope due to PlanetScope's georeferencing accuracy and...
(version 3.4.1). The distance between each pair of species was defined as the difference value between 1 and the corresponding Spearman’s rank correlation coefficient. Spearman’s rank correlation coefficient values were plotted on the heatmap and distances between different pairs of species were ...
Methods Analysis. Suspended particle was filtered onto pre-combusted GF/F filters12, and was then separated from the filters for further analysis. Prior to the measurement of POC concentration, samples were treated with 1N HCl at 60 °C for 16 h to remove carbonate; the residue was...
Studies have estimated these soils may release up to 3000 µg Hg m−2 per cm of soil eroded [72]. Consistent with this assumption, Lacerda et al. [74] concluded that the remobilization of Hg naturally present in forest soils during conversion of forest to other land uses, and not ...
