We work on the pressing challenges that bedevil the livelihoods of many millions of Africans.


The Institute was born out of the Pegasys Management Consulting Group and is based in Pretoria, South Africa. It is headed by Ms. Barbara Schreiner, Executive Director.

Our work takes place at global, continental, national and regional levels.

We are innovative, practical and extraordinarily ambitious in our goals. This is entirely appropriate, considering the sheer scale and weight of the current and future challenges Africans face.

We work on the pressing challenges that bedevil the livelihoods of many millions of Africans.

We seek to shape every African nation’s ability to grow and develop. For this to happen, we will need to transform the way every resource is captured, produced, protected, distributed, managed and used.

Pegasys Institute leaves no stone unturned in its work to rid Africa of poverty and enable the continent’s inhabitants to develop decent livelihoods based on sustainable and equitable use of natural resources.

Through the Institute, Pegasys is changing lives by altering the way in which people think about Africa and its development.

Pegasys Institute’s primary stakeholders are communities, governments and the corporate sector.
