Satellite Remote Sensing of Savannas: Current Status and Emerging Opportunities

Figure 1

Observing multiple drivers and processes in a savanna from space. Savannas have a distinct seasonality with alternating dry and wet seasons. They have a continuous layer of grass with sporadic woody cover. The grass layer provides fuel for extensive fires that coincide with the dry season, and there is widespread herbivory from grazing and browsing animals. Savannas are also subject to human activity such as livestock rearing by pastoral nomads, cropland expansion, and fuelwood harvesting. The illustrated satellites exemplify the main types of Earth observation systems that have been used to study savannas at large scales.
