Comparative analysis of soil organic carbon storage under different land use and land cover in Achanakmar, Chhattisgarh
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 1
Abstract
In context to the India’s climate pledge and the goal of limiting global warming below 2C to reduce the emissions intensity of its GDP by 33 to 35 percent by 2030 from 2005 level and to create an additional carbon sink of 2.5 to 3 billion tons of CO2 equivalent through additional forest and tree cover by 2030. Forest vegetation and forest soils represent a significant sink for atmospheric CO2, soil biota functioning, reduction of greenhouse gases, modification of pollutants and maintenance of soil quality. The great importance of carbon sequestration emphasizes the need to understand the role of soil carbon dynamics and quantitative changes as affected by different land use pattern and vegetation cover management. However, knowledge on the impact of different land use and vegetation cover on soil carbon dynamics in India is very limited. To address this problem the present study was undertaken in Achanakmar, Chhattisgarh to estimate soil carbon sequestration potential of four land uses (forestland, grassland, agricultural land and wasteland) and five land covers (sal, teak, bamboo, mixed, open and scrub). The highest soil carbon storage potential was found in forestland (118.14 t ha-1) followed by grassland (95.54 t ha-1), agricultural land (75.70 t ha-1) and least was found in the wasteland (57.05 t ha-1). Among the different land covers, maximum soil carbon storage potential was found in the soils under mixed land cover (118.18 t ha-1) followed by teak (76.64 t ha-1), bamboo (67.21 t ha-1), sal (64.28 t ha-1) and least under soils of open and scrub (48.72 t ha-1) land cover.
