Sulfur dioxide, or SO2, is a colorless, pungent gas that can be both air pollutant and important atmospheric component, depending on where it resides. Along with water vapor and carbon dioxide, sulfur dioxide is one of the most abundant gas emissions during volcanic eruptions.

The following link shows the emission and transport of sulfur dioxide from the Grímsvötn Volcano in Iceland at the end of May 2011.

More and more such studies are crucial in understanding the patterns and factors associated with long-range transport of sulphur dioxide emitted from volcanic eruptions or otherwise.

India’s Forest Cover accounts for 20.6% of the total geographical area of the country as of 2005. In addition, Tree Cover accounts for 2.8% of India’s geographical area.

Over the last two decades, progressive national forestry legislations and policies in India aimed at conservation and sustainable management of forests have reversed deforestation and have transformed India’s forests into a significant net sink of CO2.

Following link is a report of Ministry Of Environment and Forests, Government of India summarizing impact of various programmes and policies in this direction.
