Earth Observations and Modelled Data for Ecosystem Accounting

Ecosystem Accounts are inherently spatial accounts, with the implication that they strongly depend on the availability of spatially explicit datasets, including Earth Observations. EO is widely recognized as a major source of information to monitor the extent and condition of ecosystems and services provided. The advent of dense EO data streams at appropriate scales combined with the emergence of digital technologies offer unprecedented opportunities for countries to monitor the extent and condition of their ecosystems, determine ecosystem services and to use this information in compiling ecosystem accounts.

The time is now to leverage the power of Earth Observations in Ecosystem Accounting and Ocean Accounts.

Further development utilising Sentinnel2 datasets is underway and for more national scale modelling applications and cutting edge oceanographic modelling  visit the SAEON Egagasini Node and their SOMISANA teams website for current work in this space.
