I have a great pleasure in presenting this report to the International Union of Geodesy and Geophysics (IUGG) at its General Assembly in Melbourne, Australia during 28th June, to 7th July, 2011. The report summarizes Indian activities in the geophysics and geodesy for the period of January 2007 to December 2010 and is structured to reflect eight associations of IUGG. The quadrennium 2007-2010 has been very exciting for the earth system sciences internationally and India is no exception to it. Four International Science Years namely, International Year of Planet Earth (IYPE, 2007-2009), International Polar Year (IPY, 2007-2008), Electronic Geophysical Year (EGY, 2007-2008) and International Heliophysical Year (IHY, 2007) were successively complemented during this period. These years have brought a lot of visibility and importance to the earth science research. India was a lead associate of these initiatives. Indian researchers have been actively involved in the Antarctic and Arctic studies and assessments of Himalayan glaciers, which have been summarized by Rasik Ravindra in the chapter on Cryospheric Sciences.
