World Space Week, currently underway, is an opportunity to take stock of how far the continent has come in the space technology age and the benefits it stands to gain from investment. Etim Offiong outlines the potential for African countries to apply space technology in various areas including agriculture, transport, urban planning and disaster management. But countries will need to be more deliberate in developing space capabilities.
Income support for citizens has become a more pressing issue in countries faced with growing joblessness and rising food prices. South Africa is a case in point. A highly polarised debate in the country has pitted those in favour of extending the country’s social grant system to cover more people against those who are adamant the country can’t afford such a move. Hylton Hollander, Daan Steenkamp and Roy Havemann argue that what’s been missing is a modelling
that compares – or tests – the impact of the different policy choices and their permutations and how these are funded and who benefits and who loses. In a recent paper they set out their findings.
