New Delhi: With a steady flow of foreign nationals and migrants returning back home to fill vacancies for the senior level positions, reverse brain drain is going to be one of the top mega trends to influence the globe in the coming years, says a study.

According to a new report by Frost and Sullivan one of the top global mega trends the world will witness reverse brain drain, wherein the vast vacancies for CXOs in countries like India will be filled not only by returning Indians, but also by Americans and Europeans seeking better prospects.

There will be as many as two million BPO- KPO jobs for foreign nationals from China, Poland, Philippines, besides, salary given by the BRIC nations would be at par with developed countries (in terms of purchasing power) and even more benefits.

The report titled -- World's Top Global Mega Trends to 2020 and Implications to Business, Society and Cultures – aim at providing companies with special reports to focus on the evolution of these global trends to help them drive growth and innovation in a rapidly changing environment.

"Frost & Sullivan defines Mega Trends as global, sustained and macroeconomic forces of development that impact business, economy, cultures, careers and personal lives, thereby defining our future world and its increasing pace of change," Frost & Sullivan Partner, Sarwant Singh said.

Apart from reverse brain drain, other top mega trends would include urbanisation with the emergence of 30 Mega-cities.

Second most attractive trend would be e-Mobility with over 40 million electric vehicles, including electric pedal cycles, scooters, four-wheelers and buses to be sold annually around the globe in 2020.

The next level of social networking will focus on geographic services and capabilities such as geocoding and geotagging to enable additional social dynamics. This type of geo-networking will drive markets, businesses and individuals to interact advertise and promote in real time.

Women empowerment will reach new heights, with one in three workers being a woman and up to 40 per cent of boardrooms in some nations comprising women by 2020, the report said.
