A Personal Reflection on the Precautionary Principle: The Case of Water Scarcity
and Behavioural Change in Cape Town
The precautionary principle, as laid out by Kriebel et al. (2001), is a powerful yet often
contested concept in environmental science and public policy. It insists that the absence
of complete scientific certainty should not be a justification for postponing action when
there is a risk of serious or irreversible harm. Rather than placing the burden of proof on
those advocating for environmental protection, it asks those proposing potentially
harmful activities to demonstrate their safety. It is, at its core, a principle of humility and
responsibility—one that recognises the limits of human knowledge and the need to act
in ways that prevent harm before it occurs.
In considering how this principle has manifested in my own lifeworld, I turn to the deeply
impactful experience of the Cape Town water crisis between 2017 and 2018, and more
specifically, the years that followed, during which the city government implemented a
range of precautionary policies to avoid a repeat of the near-catastrophic conditions that
culminated in the threat of “Day Zero.” Though the actual crisis has passed, its legacy
remains, and I found myself, along with millions of other Capetonians, subject to new
policies designed to change our relationship with water indefinitely.
After 2018, even when dam levels began to recover, the city did not wait for evidence of
future drought before it acted. Instead, municipal authorities applied the precautionary
principle by enforcing sustained water restrictions, upgrading infrastructure to reduce
