In The Enigma of Capital: And the Crises of Capitalism by David Harvey on page 240 the author alludes to an "… anti-democratic, money-saturated and carcareal drift of capitalist state policies…" which, as far as I can see, is the only time the word 'carcareal' occurs in the book.
I've searched Google and some on-line dictionaries but so far haven't found any definition or use of the word in a similar context that would give me a clue what it means. To me the context makes me think of the word 'carcass' and connotes morbidity and death but that's a wild guess.

Carcareal is almost certainly a variant of carceral meaning "like a prison".
Both seem fairly rare, and restricted to post-modernist writers such as Michel Foucault. You will find phrases such as "carcareal archipelago" or "carceral archipelago", which seem to mean the division of society into prisons, mental institutions and gated communities, with surveillance everywhere.
