Soil erosion and carbon storage (2001-2020) for the farm of the Faculty of Agricultural Sciences Sabaragamuwa University of Sri Lanka
The database consists maps of soil erosion and carbon storage in the farm of the Faculty of Agricultural Sciences Sabaragamuwa University of Sri Lanka. The database contains predictive soil erosion, total soil loss, sediment export, sediment retention maps and total carbon storage maps in raster format for the 2001-2020 period.
Steps to reproduce
Soil erosion and carbon storage of the study area were estimated using Integrated Valuation of Ecosystem Services and Trade-offs (InVEST 3.9.2), InVEST Sediment Delivery Ratio (SDR) and InVEST Carbon models introduced by the Natural Capital (NatCap) Project, collaboration with Stanford University-USA. The model uses combined information of Digital Elevation Model (DEM), rainfall, soil properties and Land Use Land Cover (LULC) patterns in the study area to predict the changes in soil erosion. The same projected coordinate system (Kandawala_Sri_Lanka_Grid) was used for all raster inputs. All the output maps are available in raster format. This data provides complementary information of the farm of the Faculty of Agricultural Sciences, Sabaragamuwa University of Sri Lanka at finer resolution which can be effectively used for proper land conservation practices and for other agricultural decision making.
