Prime Minister has called for collective scientific efforts to combat the global challenges including climate change. Addressing a conclave of scientists in Hyderabad, Dr.Manmohan Singh said the developing countries lack a well organised system besides facing the problems of shortages of skilled man power and appropriate research facilities to cater to the needs of modern day challenges. He therefore, appealed to the advanced scientific community to join hands with the developing world by pooling together the resources and wisdom to fight transnational problems like diseases, hunger, poverty and the adverse impact of global warming. He said the impact of climate challenge is most devastating in developing world and therefore the concerns of developing countries need to be devised more forcefully in policy formulations. Dr.Singh further added that in the absence of technology transfer from the advanced countries, the developing nations have to renew their determined efforts to find solutions relevant to their needs and circumstances. Earlier the Prime Minister inaugurated the annual meeting of the academy of sciences for developing world for 2010 and gave away awards to distinguished scientists.
