Accelerated Socio-economic Development in Emerging Markets & Africa:

Emerging markets

IES is increasingly focused on skills upgrading and inward investment, providing targeted, effective advice on capacity-building for businesses in emerging markets.

Working with government, institutional clients and business clients in emerging markets, IES can help accelerate growth by mapping broad socio-economic challenges, managing multiple stakeholder dynamics and implementing carefully planned strategies for development to achieve the full potential of a business, sector, or regional economy.


Africa today represents a major business and investment opportunity. Whilst current financial and economic circumstances challenge business around the world, IES is confident Africa will play a rapidly growing role in future global economic growth, thereby also ensuring its own successful development and continent-wide economic and social progress.
