FOSSIL AND NON-FOSSIL CARBON

AND GREENHOUSE GAS REDUCTION

………………..

How we arrived at the distinction betweenfossil vs non-fossil carbon?

Some Northern countries suggested to substitute emissions reduction with carbonsequestration by their existing forests.

Whereas Southern countries had to reducecarbon emissions and cannot use sequestration!

This is why we have come up with a new approach based on the distinction betweenfossil carbon and non-fossil carbon.

This allows to ShowMNM :

• the merit of non-fossil carbonsequestration for developing countries and

• the need for reducing fossil carbonemissions in industrialised countries.

In short, southern countries whose main emissions are non-fossil carbon can adoptcarbon sequestration options,

While developed countries who have mostlyfossil carbon emissions must adopt thereduction option.

LE CARBONE DANS LA NATURE :

AGRICULTURE: A CARBON SOURCE AND A CARBON SINK

I - Agriculture source de carbone

• Use of wood for heating and cooking

In Senegal,

• agricultural production is 2.5 million tons p.a. and

• wood consumption is 3 million tons p.a.

• Land conversion for agriculture.

In Africa, every year, millions of hectars ofland are converted for extensive and low-productivity agriculture.

In Senegal, the figure is 80 000 ha p.a..

In Senegal, non-fossil carbon emissionswere 3.5 million tons of carbon equivalent in 1995.

Conclusion :

in these farming systems and consumptionpatterns more food production means more carbon emissions.

Agriculture II – as a carbon sink

• Hedges or windbreakers of perennialswhich surround the farms sequester carbonabove below ground as well as produce a conducive environment for production

Conclusion : in carbon sink agroforestrysystems, the more you produce food, themore you produce wood for cooking or for carbon sequestration.
