title = "Estimating Trends and Variation of Net Biome Productivity in India for 1980–2012 Using a Land Surface Model",
abstract = "In this paper we explore the trend in net biome productivity (NBP) over India for the period 1980–2012 and quantify the impact of different environmental factors, including atmospheric CO2 concentrations ([CO2]), land use and land cover change, climate, and nitrogen deposition on carbon fluxes using a land surface model, Integrated Science Assessment Model. Results show that terrestrial ecosystems of India have been a carbon sink for this period. Driven by a strong CO2 fertilization effect, magnitude of NBP increased from 27.17 TgC/yr in the 1980s to 34.39 TgC/yr in the 1990s but decreased to 23.70 TgC/yr in the 2000s due to change in climate. Adoption of forest conservation, management, and reforestation policies in the past decade has promoted carbon sequestration in the ecosystems, but this effect has been offset by loss of carbon from ecosystems due to rising temperatures and decrease in precipitation.",

note = "Funding Information: The four sets of gridded terrestrial carbon fluxes outputs (GPP, NPP, NBP, Ra, Rh, and land use emission) simulated using ISAM for India under four different experimental discussed in the paper can be downloaded from the ISAM model website: http://climate.atmos.uiuc.edu/ Gahlot_etal_GRL_Data.tar.gz. These runs were conducted from 1801 to 2012, and here we provide the results from 1980 to 2012, which is the period the paper mainly focusing on. Part of the research was carried out under a visiting fellowship offered to Shilpa Gahlot by the University of Illinois under NASA grant (NNX414AD94G). Atul K Jain and Shijie Shu were supported by the NSF (NSF AGS 12-43071) and the US DOE (DOE DE-SC0016323). We thank Prabir Patra from JAMSTEC Japan for providing us the top-down model-estimated NBP results presented in Table 3. Publisher Copyright: {\textcopyright}2017. American Geophysical Union.
