Satellite Remote Sensing of Savannas: Current Status and Emerging Opportunities
Variability in aboveground biomass (AGB) estimates from eight tropical savanna ecosystems. The savanna delineation in the central panel (pink color) depicts subtropical and tropical grasslands, savannas, and shrublands according to the Ecoregions 2017 dataset . (a–h) Show examples of different ecosystems within this area and their corresponding ecosystem-wide AGB in megagrams per hectare (Mg ha-1): (a) Yucatan Dry Forests (), (b) Sahelian Acacia Savanna (), (c) Central Deccan Plateau Dry Deciduous Forests (), (d) Central Indochina Dry Forests (), (e) Guianan Savanna (), (f) Cerrado (), (g) Eastern Miombo Woodlands (), and (h) Kimberly Tropical Savanna (). The AGB data in this figure is based on Avitabile et al. , who harmonized two earlier AGB maps by Baccini et al.  and Saatchi et al.  with field data at a 1 km spatial resolution.
