The study was conducted in Joida and Karwar talukas of Uttara Kannada district, Karnataka, to assess the effect of land use land cover on carbon sequestration in soil. The IRS P6 LISS-III imageries were used for generating of LULC thematic map of study region and are classified using ERDAS-2011 software with ground truth data collected through GPS. The land use classes viz., dense forest, agriculture land and barren land were identified. The soil samples up to one meter depth were collected from each land use system and SOC was estimated. The result indicated that the soil organic carbon in different land uses were significantly different. The total SOC in Joida and Karwar taluka was 20.69 and 7.42 million tons respectively. The average SOC in Joida and Karwar soil was 83.59 and 85.06 t/ha respectively. The carbon mitigation potential in dense forest soil was 2.13 and 2.28 times more in Joida and Karwar taluka respectively as compared to Agriculture soil. The forest cover helps sequester more carbon in soils and reduce green house gases from atmospheres.Keywords

The study was taken up in Mundgod taluka of UK (Uttara Kannada) district to assess the anthropogenic impact on forest resources. The forest area from 1989 to 2006 was analyzed using LANDSAT TM and ETM+ imageries in ERDAS IMAGINE and Arc GIS. The result revealed that the forest area in the year 1989 was 78.59% which was reduced to 64.65% in the year 2006 mainly due to human interference. There has been an increase in area under agriculture and water body. The detection of change in forest area was identified through NDVI maps. The increase in agricultural land was due to cultivation in forest land by cutting the trees, there by reduced the forest area. The trend of result indicated that the forest resources are decreasing year by year due to human activities.Keywords

The topographical factors such as aspect and altitude play an important role on carbon sequestration process and soil organic carbon pool in forest soil. The study was conducted in Ankola taluka of Uttara Kannada district to assess the effect of aspect and altitude in dense and sparse forest on soil organic carbon pool. The result indicated that the western and eastern aspects have positive influence on carbon sequestration in soils of both dense and sparse forest as compared to northern and southern aspect. The mid altitude (200-400 m) favored the SOC sequestration significantly higher followed by lower altitude (0-200 m) and least SOC pool was found in higher altitude (>400 m). On an average the SOC pool in dense forest, irrespective of the aspect mid altitude recorded higher SOC pool (185.17 t/ha) followed by lower and higher altitude as 152.86 t/ha and 148.79 t/ha respectively. Similarly on spares forest mid altitude recorded higher average SOC pool (174.59 t/ha) followed by lower (172.08 t/ha) and higher altitude (154.84 t/ha). Based on the result it is concluded that western and eastern aspect with mid altitude favored the carbon sequestration in soils of both dense and spares forest of Ankola taluka in Uttara Kannada district.Keywords
