Maranhão Brazil


Forest monitoring systems are a fundamental component of Brazil's REDD + efforts, since they provide key information for the planning of public policies. Maranhao uses systems based on remote sensing, using information collected by satellites. Brazil has systems that allows monitoring of forest cover over time, identifying where deforestation is occurring, analyzing the dynamics of land use, and others.

In addition, monitoring systems allow for the elaboration of historical series for REDD + activities and periodically generate data for results to be measured from the reference levels of forest emissions based on the historical series.

The main developer of monitoring systems in the country is the National Institute of Space Research (INPE), linked to the Ministry of Science, Technology, Innovation and Communications. INPE has the PRODES project, which carries out satellite monitoring of shallow-deforestation in the Legal Amazon and has been producing annual deforestation rates in the region since 1988, which are used by the Brazilian government to establish public policies. The annual rates are estimated from the deforestation increments identified in each satellite image that covers the Legal Amazon.

In this way, the state of Maranhão uses this system to monitor deforestation in the state's forests and then make emission reduction estimates for deforestation.
