Science, astronomy, and sacrifice zones: development trade-offs, and the Square Kilometre Array (SKA) radio telescope project in South Africa

Abstract

ABSTRACT We explore the notion of “sacrifice zones” to reflect critically on the trade-offs between Science & Technology (S&T) policy and inclusive development in South Africa. We draw evidence from one of the country’s flagship projects, the Square Kilometre Array (SKA) radio telescope, currently under construction in the semi-arid Northern Cape. The SKA embodies a key tension in the country’s S&T policy, that between the promotion of astronomy, based on national and global priorities (the development of science), and the advancement of local development concerns (science for development), in which the dominant assumption is that local interests are either subsumed or superseded by national and global public goods. Given the extent to which the priorities of local residents have been overlooked in the name of the greater good, we argue that a fruitful way of recasting this relationship is to regard the region around the telescope as astronomy’s terrestrial “sacrifice zone”; this opens up an important space for engaging with issues of mitigation. We conclude by raising questions about who should take responsibility for mitigating the trade-offs in policy and practice, if a more sustainable and inclusive development agenda in the areas affected by the SKA is a real concern.
