While being hailed as the world's top outsourcing destination, India has eight of its cities named as among the world's 25 riskiest places for offshoring due to terrorism, pollution and geopolitical issues, reported the local daily Hindustan Times Sunday.

The national capital region comprising Delhi Gurgaon and Noida has earned the dubious distinction of being the worst offshoring destination within the country in a survey in the annual Black Book of Outsourcing, said the report.

The National Capital Region is followed by Mumbai, which is regarded as the second riskiest offshoring hub in India, said the report.

The other Indian cities named in the global list of 25 riskiest offshoring destinations are Bangalore, Hyderabad, Chennai, Pune, Chandigarh and Kolkata.

In the overall global list, National Capital Region of India has been ranked as sixth most riskiest, Mumbai ninth, Chandigarh 15th, Pune 20th, Chennai 21st, Bangalore 23rd, Hyderabad 24th and Kolkata the 25th most riskiest in the world.

Meanwhile, no Indian city has managed to find a place on a separate list of 25 safest offshoring destinations, said the report.

Both the lists have been published in the 2009 edition of the Black Book of Outsourcing, brought out every year by U.S.-based Brown-Wilson Group.
