The land-use sector can contribute to climate change mitigation not only by reducing greenhouse gas (GHG) emissions, but also by increasing carbon uptake from the atmosphere and thereby creating negative CO2 emissions. In this paper, we investigate two land-based climate change mitigation strategies for carbon removal: afforestation and bioenergy in combination with carbon capture and storage technology (bioenergy CCS).

Human exposure to particulate matter (PM) was determined in Urban Environment of Delhi, India. Samples were collected using eight stages impactor (Marple Cascade Impactor) at five sites during August to October 2011. Three samples were collected from each site; samples were analyzed in eight size ranges gravimetrically and chemically (for metals). Maximum (985 μg m-3) exposure to PM was in Okhala an industrial site and minimum (404 μg m-3) in Jawaharlal Nehru University, an educational Institute.
