ABSTRACT
The aim of the presented study is to quantify the total carbon stock of habitats in addition the estimation of
aboveground and belowground biomass, necromass, and soil organic carbon. Prediction of carbon storage under
climate change is based on future land-use changes, identification of new land-use distribution, and evaluation of
changes in human impacts on biomass production and carbon storage. Widely used InVEST model was applied to
determine the existing carbon stocks and the amount of carbon captured over time. Changes in the carbon
storage were calculated from aboveground biomass, belowground biomass, necromass, and soil organic carbon
pools. The original model was modified to vector space to better identify land heterogeneity. The values of the
four carbon pools for individual land-use categories were derived from literature and experimental investigation.
Land Change Modeller was then used to model future land use by applying business-as-usual scenario on data
derived from 1990, 2000, 2006, and 2012 Corine Land Cover data. In this contribution, land cover predictions
are calculated using three CORDEX climate models and two emission scenarios (RCP 4.5 and RCP 8.5). Results
describe current carbon stock by basic carbon pools and prediction of the total amount of carbon stored in four
reservoirs in three time period. Results show that the difference in predictions between specific scenarios in each
period is increasing and in all predictions, roughly the same proportional carbon ratio is maintained between the
individual stocks.
1. Introduction
Ecosystems regulate Earth's climate by adding and removing
greenhouse gases such as CO
2
from the atmosphere. Forests, grasslands,
peat swamps, and other terrestrial ecosystems collectively store much
more carbon than does the atmosphere (Lal, 2004). By storing this
carbon in wood, other biomass, and soil, ecosystems keep CO
2
out of
the air, where it would contribute to climate change (Watson et al.,
2000). Beyond just storing carbon, many ecosystems also contribute to
its accumulation in plants and soil over time, thereby “sequestering”
additional carbon each year. Disturbing these systems with fire, disease,
or vegetation change through land use/land cover (LULC) conversion,
significant amounts of CO
2
is released into the atmosphere (Kareiva
et al., 2011). Therefore, information on current soil carbon stocks and
possible changes are needed in the context of the United Nations Fra-
mework Convention on Climate Change. Managing landscapes for
carbon storage and sequestration require information about volume and
location of already stored carbon, quantity of carbon sequestered or lost
over time, and relationship between land use change and its effect on
carbon storage and sequestration over time (Oulehle et al., 2011). A
terrestrial-based carbon sequestration process is perhaps the most
widely recognized of all ecosystem services (Canadell and Raupach,
2008; IPCC, 2006; Pagiola, 2008; Stern, 2007).
Determination of carbon stocks in the aboveground biomass can be
accomplished by a variety of methods, including both contact field
measurements and contactless measurement using remote sensing.
Contact measurement methods always provide more accurate results
but they are costly and time consuming (Brown, 2002; Coomes et al.,
2002; Gibbs et al., 2007; Machar et al., 2016). Therefore, for large
areas, the contact methods are almost unusable. That is why in present
time numerous studies are devoted to incorporate remote sensing
technology for quick and contactless determination of carbon stocks
(Goodenough et al., 2005; Mandal and van Laake, 2005; Vicharnakorn
et al., 2014).
