Table 4. Summary mangrove and seagrasses Corg stocks acording to the cover extent. Estimated mangrove emissions are shown with their associated land use change per geographic region.
Mangrove emissions were calculated for the time period 1970-2015 ussing a conservative approach of 25% loss of the total storage. Main factors of change: 1. Aquaculture farms and artificial ponds, 2. Construction areas, 3. Hydraulic infrastructure, 4. Communication routes, 5. Industrial zones and 6. Turistic zones (from Valderrama-Landeros et al., 2017).
