Soil; Carbon Stock

The increase in atmospheric carbon dioxide (CO2) concentration is one of the main environmental issues nowadays. This is because CO2 is the primary cause of global warming. The main sources of the emitted CO2 are combustion of fossil fuels and land use change such as deforestation. Land use changes, for example, the conversion of nature forest to agricultural lands, therefore leads to the loss of carbon from plants and ecosystem to the atmosphere (Bonan, 2002). Carbon translocation from the atmosphere to occurs due to photosynthetic plant growth and the decomposition of carbon-containing material and is subsequently incorporated into the soils. Uptake by terrestrial through photosynthesis by plants is the major sink for atmospheric carbon. Because forest is the main terrestrial ecosystem that stores or fixes the atmospheric CO, it continues to accumulate carbon as plants grow and carbon is then preserved in the forest floor as plants In the tropics, forest is rapidly being converted to agricultural land for food production for the rapidly increasing population. Between 1850 and 1980, the area of forests and woodlands of the world decreased by 11% (603 Mha) (Houghton, 1999). About 84% of this is in the tropics and about 15% in the temperate zone. This results in, in addition to the release of carbon from energy consumption, a substantial increase in carbon dioxide concentration in the atmosphere. To understand and finally to find the appropriate options to stabilize or reduce the atmospheric CO2 concentration, the carbon dynamics in the tropics must be undestood. Much of our understanding of the carbon flow tow tortethth flow to date is derived from the investigate temperate zone. Since deforestation has mainly occurred in the tropics, knowledge on the effects of deforestation on carbon dynamics need to be urgently established.
