Ocean researchers have learned much since the American biologist Rachel Carson observed in 1937: “Who has known the ocean? Neither you nor I.”  But, says … Read More

Supporting a Forest Observation System for Siberia: Earth Observation for Monitoring, Assessing and Providing Forest Resource Information

EarthzineEcosystems, Original

he monitoring and assessment of the remote Russian forest resources of Siberia is challenging and can only be done by integrating remote sensing techniques. Human and environmental forest disturbances continuously affect changing forest cover and biomass levels. The ZAṔS initiative is prototyping and supporting a forest observation system for Siberia using Earth observation data from European and Russian satellite data providers.

Such an approach, as seen in the Biomass Geo.Wiki tool, is inexpensive and allows Internet users from anywhere in the world to become involved in this global validation exercise.
