What are the vocations of those leaving ?

There is some indication here . The historic relationships have been with South Africa but there has been a growing willingness in the country to look to a broader community. Obviously there has been some linkage to the UK for historic reasons, but with increasing globalization and with China, in particular, being more diligent in finding potential future fuel sources and industrial opportunities, those older relationships are under increasing challenge. Recent major investments in the country have included some from Russia, but the market for technically competent individuals in the global marketplace is such that without stronger incentives it may become more difficult for countries such as Botswana to retain their best and brightest.
