Resumen:
Ecosystem service (ES) models can only inform policy design adequately
if they incorporate ecological processes. We used the Lund-Potsdam-Jena
managed Land (LPJmL) model, to address following questions for Mexico,
Bolivia and Brazilian Amazon: (i) How different are C stocks and C
sequestration quantifications under standard (when soil and litter C and
heterotrophic respiration are not considered) and comprehensive
(including all C stock and heterotrophic respiration) approach? and (ii)
How does the valuation of C stock and C sequestration differ in national
payments for ES and global C funds or markets when comparing both
approach? We found that up to 65% of C stocks have not been taken into
account by neglecting to include C stored in soil and litter, resulting
in gross underpayments (up to 500 times lower). Since emissions from
heterotrophic respiration of organic material offset a large proportion
of C gained through growth of living matter, we found that markets and
decision-makers are inadvertently overestimating up to 100 times C
sequestrated. New approaches for modelling C services relevant
ecological process-based can help accounting for C in soil, litter and
heterotrophic respiration and become important for the
operationalization of agreements on climate change mitigation following
the COP21 in 2015.
