"Iran ranked 17th in the world in production of science in 2011 and the growth rate of science production in the country is 11 times higher than the world average," Davoud Younesian, an official in charge of studying the recent progress in Iran's railway engineering, said in Tehran on Tuesday.
He appreciated Iranian experts and scientists for their huge progress, and said while Iran ranked 24th in the world in producing science in 2007 by presenting 14,000 scientific productions, it ranked 17th in 2011 in the same field, which is a great achievement.
Iran has taken wide strides in science and technology in recent years.
In March, Iranian Minister of Science, Research and Technology Kamran Daneshjou announced Iran's astonishing growth in the world's scientific output, and said that Iran's world rankings in different scientific scales have improved.
"The Islamic Republic of Iran has improved its ranking to 17 in 2013 from 20 in 2012 in the scale of Institute for Scientific Information (ISI) and to 15 in 2013 from 17 in 2012 in the Scopus scale," Daneshjou said at the time.
He noted that reference to scientific journal articles written by Iranian scientists has increased in recent years which shows the quality of these articles.
Also in March, a government report said Iran's ranking in the field of nanotechnology has considerably improved in the past eight years.
Iran now stands 9th in the world and 1st in the Middle East in the field of nanotechnology.
The report noted that attaining the 29th place in the world and 2nd place in the region in area of registered nano inventions has also been among the country's achievements in the last eight years.
Last year, an Iranian official announced that Iran stands 14th in the world ranking of biotechnological advancements.
"Iran has attained desirable capabilities in the field of biotechnology in recent years and has ranked 14 among the 46 world states which are active in this arena," Head of the Presidential Office's Technological and Innovations Cooperation Center Hamidreza Amirinia said in Tehran in December.
"Today the development of biotechnology has increased the level of social welfare, developed the exports market and created health tourism infrastructures in the country," he added.
