SUMMARY:

Carbon stocks are an ecosystem service, one of the many benefits provided by
nature. Anthropic actions, mainly due to economic growth through the implementation
and maintenance of projects, have been responsible for the loss and impairment of the
benefits derived from ecosystem services. The objective of this research was to measure
the environmental liability of the loss of one of the most important ecosystem services
provided by tropical forests, the carbon stock, in the area where Porto Sul, a large port
complex that is currently being installed in the municipality of Ilhéus in the interior of
Bahia, is located. Different phytophysiognomies were mapped in the area of influence
of the project, including forest in the initial and medium stages of regeneration, restinga,
mangroves and cocoa agroforests (Theobroma cacau) in a traditional system known
regionally as cabruca. For each phytophysiognomy, above-ground biomass was
calculated using allometric equations and the Empirical Bayesian Kriging tool was used
as a geostatistical interpolation method. After quantifying the above-ground biomass,
the total carbon found was priced in five different price scenarios and the price of the
timber forest product and the restoration product were added to the economic analysis to
arrive at the opportunity cost of the enterprise. The average carbon stock per
phytophysiognomy was 2.77 t/ha-¹ for cabruca, 2.90 t/ha-¹ in the forest in the initial
stage of regeneration, 3.39 t/ha-¹ in the forest in the medium stage of regeneration, 2.06
t/ha-¹ restinga and 3.15 t/ha-¹ mangrove. The carbon price varied from U$ 44,402.05
tC/ha/year to U$ 1,291,696.00 tC/ha/year, the price of the timber forest product was U$
58,541.26 and the average cost per hectare to restore the area with native vegetation was
U$2,562.91, cabruca U$31,583.40, restinga U$2,978.83 and in the mangrove
U$2,976.80. It was therefore possible to quantify and price one of the many ecosystem
services affected by the arrival of Porto Sul in the municipality of Ilhéus. Measuring the
environmental liabilities of these projects is fundamental for monitoring the effects of
human actions on biodiversity, while the economic analysis evaluates one of the
consequences of the degradation of these ecosystems on a social level.
