Assessment of Carbon Sequestration
in Soils of Different Land Use Land Cover
in Honnaver Taluka of Uttara Kannada
District

Abstract The study was conducted in Honnaver taluka (14° 8′ 0″ N to 14° 25′ N
Latitude and 74° 25′ E to 74° 45′ E Longitude) of Uttar Kannada district, Karnataka
India to assess the carbon sequestration in soils of different land use systems.
The IRS P6 LISS-III imageries of the study area was procured from NRSC,
Hyderabad and different land use systems in Honnaver taluka were identified with
the ground truth data collected from GPS and processed in ERDAS software. The
land use land cover (LULC) classes, viz., dense forest, sparse forest, agriculture and
open land were identified. The total area in each class was assessed through
supervise classification. The soil samples at 1 m depth were drawn at grid point in
flat land and along the profile in sloppy land in different land use system. The SOC
was estimated using Walkley and Black rapid titration method. The total area in
four land use classes is 68520 ha with SOC pool of 12.112 million tonnes. Among
different classes dense forest covers highest area (44053 ha) and highest SOC pool
(8.82 million tonnes). Among the different land use classes, higher SOC was
sequestered in dense forest (200.10 t/ha) followed by sparse forest (166.89 t/ha).
The SOC in open land and agriculture land is 145.78 and 82.79 t/ha, respectively.
The carbon mitigation potential of dense forest is 2.42 times higher compared to
agricultural land followed by sparse forest (2.02 times).

1 Introduction
Global warming has become a problem for the society due to carbon emission in the
wake of modernization and urbanization. Global surface temperatures have
increased by 0.8 °C since the late nineteenth century, and 11 out of the 12 warmest
years on record have occurred since 1995 (IPCC 2007). Carbon sequestration is the
