CDCOL - Colombian Data Cube Forest and Carbon Monitoring System
SECTORAL AT THE SERVICE OF SCIENTIFIC INFORMATION AT THE SERVICE OF SECTORAL PLANNING Ecosystem and Environmental Information Department F&C Monitoring System Statistic Certification (3 years) Reports Environmental Indicators for SDG 6 15 www.ideam.gov.co/web/ecosistemas/ecosistemas-recursos-forestales
FOREST AND CARBON MONITORING SYSTEM Since 2013 Annual Early warning Identifying hot spots Carbon monitoring - Carbon stocks - GHG Emissions National quantification of deforestation - Forest areas - Forest change detection Deforestation rate Since 2016 Quarterly C&A Deforestation and Degradation - Caracterization - Modelation 1 3 2 4 5 6 7 8
Deforestation in Colombia Deforestation rate 44% 178.597 ha 2016 124.035 ha 2015
Deforestation drivers Direct causes of deforestation Pasture conversion Road infrastructure Illicit crops Mineral extraction (illicit *) Extensive cattle raising Forest Fires 7 hotspot 1990-2000 2016

Lesson Learned and recommendations Is important to define agreements between national entities to establish responsibilities for reporting SDGs Also, is important to build capacities in order to continue the statistic operations for generating official information Is needed a national capacity for administration the Data Cube and for creation of new algorithms (python) in order to support new information products (SDG) Is needed a very powerful technological infrastructure to manage the Big Data of EO (which is growing exponentially)
