The Intergovernmental Panel on Climate Change (IPCC) asserts that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activities such as fossil fuel burning and deforestation. This study assessed the situation in Akwa Ibom State, Nigeria as far as deforestation and fossil fuel burning was concerned. The study revealed that, within a period of 21 years [1986-2007], more than 50% of forest covers in the area was lost due to deforestation. Based on a handful of biome-average estimates this forest cover stored 53,003,200 tons of carbon which was released as CO2 into the atmosphere as a result of deforestation. Moreover, the same forest cover would have sequestered 300,305.5 tons of carbon dioxide if it was not cut down. Also, the area is witnessing urban growth patterns that are compact and without green belts that can serve as sinks for carbon emissions from anthropogenic activities within area. The study concluded that an integrated information system that includes a GIS with Remote Sensing image processing capabilities is a powerful tool that can help us monitor and manage our contributions to global warming among other things.
