1. Roots by respiration and organic matter with decay result into CO
2
emission in soil that may get dissolved in soil water, if present in
suitable proportion.
2. Organic matter during decomposition may get complexed and che-
lated with differing clay types restricting further decomposition.
3. Slowing down organic matter decomposition by using suitable me-
chanical and microbial techniques.
4. Humus materials either present or added to soils is resistant to fur-
ther decomposition restricting CO
2
emission.
5. Special chemical arrangement to be made to divert emitted CO
2
during decomposition of organic materials in some nonemitting
compounds in soils.
6. Low wavelength radiation (X-ray and gamma ray) often converts
soil organic carbon to nitrogen and the mechanisms need to be
quantified (Mishra et al. 2006a, 2006b, 2008).
7. EM radiation beyond 720 nm showing thermal properties may be
reflected back to the atmosphere in order to suppress the soil or-
ganic matter decomposition.
8. Soil covered with vegetation round the year may buffer the diurnal
temperature change and minimize the organic matter decay consid-
erably (conservation agriculture).
9. Agro-forestry with high CO
2
demand on the river-banks may se-
quester CO
2
by its dissolution with river water preferentially.
10. Construction of highways and railway tracks on river-banks may
facilitate green house gases to be sequestered under the influence
of agro-forestry and river water.
Importantly, soil microorganisms are the major component of biogeo-
chemical nutrient cycling and global fluxes like CO
2
, CH
4
and N. The
global soils are estimated to contain almost twice as much carbon as the
atmosphere, making them one of the largest sinks for atmospheric CO
2
and
organic carbon (Jenkinson et al., 1991).

THROUGH INTEGRATED APPROACH
The global climate change is virtually an outcome of a complex phenom-
enon in an extraordinary open system that seems to be beyond ones control
