This creates a particular spatial variation of Agamben’s (2005) state of exception concept: the ‘landscape of exception’. With respect to the possible conditions of ‘exception’, this article describes the ‘landscape of exception’ of the greenhouse system in South-Eastern Sicily. This ‘landscape of exception’ is generated by the greenhouses, in particular those dedicated to vegetable production, through an effective mechanism of spatial manipulation of the landscape and social control of migrant workers. In relation to these considerations, this work reflects on the ethical challenges and responsibilities of planning, highlighting (explicit and latent) conflicts and power inequalities in the ‘landscapes of exception’, where issues of environmental sustainability, social justice and the suspension of norms are closely intertwined.
