I’m using this model to understand how carbon storage has changed in Indonesia. I’m only considering mangroves and I’m using two LULC maps, representing the landscape in 2000 and 2018 respectively. After running the model, I used QGIS to understand the total amount (in Megatonnes CO2) of the following outpus:
- carbon_accumulation_between_2000_and_2018 = 425.223.406
- carbon_emissions_between_2000_and_2018 = 67.430.938
- carbon_stock_at_2000 = 1.225.887.507
- carbon_stock_at_2018 = 1.569.643.177
- net_carbon_sequestration_between_2000_and_2018 = 343.755.321
I know that from 2000 to 2018 the total area of mangroves has decreased, so I wonder why the carbon stock in 2018 is larger than the one of the landscape in 2000 (considering that the model does not consider growth and aging of the habitat).
On the other hand, if the model considers that the mangroves that survived until 2018 have continued to capture carbon that those results make sense.
What do you think? Do these results make sense?
