| Soil C sequestration through changes in land use and management is one of the
sustainable and long-term strategies to mitigate climate change. This
research explores and quantifies the role of soil and land use as
determinants of the ability of soils to store C along Mediterranean systems.
Detailed studies of soil organic C (SOC) dynamics are necessary in order to
identify factors determining fluctuations and intensity of changes. In this
study, SOC contents from different soil and land use types have been
investigated in Andalusia (Southern Spain). We have used soil information
from different databases, as well as land use digital maps, climate databases
and digital elevation models. The average SOC content for each soil control
section (0–25, 25–50 and 50–75 cm) was determined and SOC stocks were
calculated for each combination of soil and land use type, using soil and
land cover maps. The total organic C stocks in soils of Andalusia is 415 Tg
for the upper 75 cm, with average values ranging from 15.9 Mg C ha−1
(Solonchaks under "arable land") to 107.6 Mg C ha−1 (Fluvisols from
"wetlands"). Up to 55% of SOC accumulates in the top 25 cm of soil
(229.7 Tg). This research constitutes a preliminary assessment for modelling
SOC stock under scenarios of land use and climate change. |
