The increasing lelvel of green house gases in general and carbon dioxide in particular has raised concerns about the vulnerability of human, animal and plant life. Forests though serve as sources and sink of the CO2, there is need to synthesize the impact of climate change on forests and the role of forests in global carbon cycle.

The assessment of carbon storage potential has been difficult due to the lack of information on biomass compartmentation and carbon allocation in different species. For most of the species used for afforestation/reforestation, only the above ground biomass potentials are known but to have a picture of carbon storage potential species, the below ground biomass pattern are equally important.

Agroforestry that envisages integration of trees, herbaceous crops and/or animals on the same land unit, holds promising potential in Punjab to diversify traditional rice-wheat rotation.
