Abstract(s)
Forest ecosystems provide multiple services including climate regulation
through e.g. Carbon Storage and Sequestration (CSS). However, the
dynamics of this Ecosystem Service (ES) is strongly influenced by Land Use/
Land Cover (LULC) changes. In order to understand the influence of these
changes in the provision of this ES through time, we quantified, mapped
and valued CSS in the Sabor River’s upper basin (northeastern Portugal)
using the InVEST model. The assessment relied on the interpretation of
LULC changes between 1990 and 2006, the estimation of carbon stocks,
economic valuation and the simulation of three alternative landscape
scenarios for 2020. The results suggested that between 1990 and 2006 the
variation of the CSS occurred mainly due to changes in LULC and especially
due to the increase of the availability of forest tree biomass. Over this
period, we estimated an increase of carbon stored; its distribution among
the different carbon pools varied depending on LULC types. However, for
all LULC types, soil was identified as the main carbon pool. In the future
the expansion of forest areas in the landscape, related to a realistic
scenario of rural abandonment, can further enhance carbon sequestration,
eventually adding value to the climate regulation ecosystem service.
