Geo-spatial assessment of temporal variation of greenhouse gases emission using GIS in Jahangirnagar University, Bangladesh
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 3
Abstract
To assess the present scenario of GHGs (CO2 and CH4) emission and its distribution, day time emissions of CO2 and CH4 in August 2013 and 2014 in Jahanginagar University area were studied using statistical analysis and GIS interpretation. In 2013, maximum value of CO2 was 500 ppm which was found in Bishmile bio gas plant, Prantic gate and Dairy gate characterized by solid waste dumping site and high way road areas. Similarly in 2014, maximum value of CO2 was 600 ppm which was found around the high way road site area. In 2013 and 2014 maximum value of CH4 was 3500 ppm and 4000ppm respectively which was found in Bishmile situated in the Northern site of study area. These sites are characterized by solid waste dumping site and biogas plant area. The results of the geospatial calculations show that in 2013, 43.355% of total area covers 357.143 to 385.714 ppm concentration of CO2 while in 2014, 45.896% of the total area covers 385.714 to 428.571 ppm concentration of CO2. Apart this in 2013, 38.604% of total area covers 621.418 to 1042.18ppm concentration of CH4 while in 2014, 39.168 % of the total area covers 856.583 to 1434.818 ppm concentration of CH4. From the spatial and temporal analysis it can be said that concentration of CO2 and CH4 in this area in a rising trend. This study would also implicitly provide a mechanism to monitor potential sources of CO2 and CH4 as well as their adverse contribution to enhance GHGs emissions.
