"This product will have a major impact on our carbon budget work," says Professor Steve Running of the University of Montana, Missoula, who uses the Boston University land cover maps in conjunction with other weekly observations from MODIS."With the MODIS land cover product we can determine current vegetation in detail for each square kilometer; for example, whether there is mature vegetation, clear cutting, a new fire scar, or agricultural crops.“These maps, with spatial resolution of 1 kilometer (.6 mile), mark a significant step forward in global land cover mapping by providing a clearer, more detailed picture than previously available maps,” says Mark Friedl, one of the project’s investigators.

livestock movements) not mapped in previous assessments.

In November 2017, FAO decided to develop an updated land cover dataset, with the objective to produce baseline georeferenced information to serve applications within a portfolio of projects: The reasons for updating land cover mapping in South Sudan are numerous.

Although no systematic work has been conducted in recent years, displacement of people related to civil unrest is frequent and commonly results in increased pressure on natural resources, with deforestation and degradation of woodlands for biofuel production and land conversion to agriculture.

Recent Earth observation missions have meant that multi-temporal and multi-spectral analyses of land cover over time can be carried out more effectively than ever before.

This, combined with online cloud-computing platforms will allow improved thematic and spatial accuracy combined with time and cost-effective results.

Carbon cycle modeling is linked to greenhouse gas inventories—estimates of greenhouse emissions from human sources, and their removal by greenhouse gas sinks, such as plants that absorb and store carbon dioxide through photosynthesis.
