Prabhakar ICAR-Central Agroforestry Research Institute Gwalior Road, Jhansi (U.P.) – 284003 BACKGROUND Achievements Table 1: Common tree species existing on farmers field in different states. According to the latest IPCC report, (2014) ICAR- Central Agroforestry Research State Tree species existing in agroforestry changes in climate are unequivocal and Institute, Jhansi has been working since 2011 Punjab Eucalyptus tereticornis, Populus deltoides, Melia azedarach, Dalbergia sissoo anthropogenic green house gases are the as one of the partner of NICRA project on Haryana Eucalyptus tereticornis, Populus deltoides, Melia azedarach, Azadirachta indica major drivers of this change. Total three objectives. These include mapping of Uttar Pradesh Tectona grandis, Eucalyptus tereticornis, Populus deltoides, Azadirachta indica, Acacia nilotica, Madhuca latifolia anthropogenic GHG emissions have agroforestry area in the country (using GIS continued to increase over 1970 to 2010 with and RS), assess the carbon sequestration Bihar Tectona grandis, Leucaena leucocephala, Albizia procera, Azadirachta indica, Dalbergia sissoo larger absolute decadal increases towards potential (CSP) of agroforestry systems West Bengal Albizia procera, Terminalia arjuna, Eucalyptus tereticornis, Dalbergia sissoo, Acacia auriculiformis the end of this period (high confidence). existing on farmers fields at national level (using CO2FIX model) and evaluation of Gujarat Ailanthus excelsa, Eucalyptus tereticornis, Tectona grandis, Dendrocalamus strictus, Manilkara zapota, Azadirachta Despite a growing number of climate change indica, Tamarindus indica, Prosopis cineraria mitigation policies, average annual GHG thermotolerance of tree species for emissions grew by 1.0 Giga tonne carbon agroforestry so that right species can be Rajasthan Prosopis cineraria, Tecomella undulata, Acacia tortilis, Ailanthus excelsa, Capparis decidua, Dalbergia sissoo, promoted for plantation under increased Azadirachta indica dioxide equivalent (Gt CO2e) (2.2%) per year from 2000 to 2010 as compared to 0.4 Gt thermal regime in future.
