Tourism Carrying Capacity Assessment

Because limits operate on several independent dimensions. O'Reilly distinguished physical and ecological capacity (what the resource can withstand), social capacity (what hosts and visitors will tolerate before satisfaction falls), and economic capacity. These often diverge, and the meaningful limit is the lowest of them — the binding constraint. Reducing all of this to one figure hides which dimension actually limits use and creates a false sense of precision, which is why modern practice reports capacity as a multidimensional, indicator-based judgement.

Carrying capacity is the mechanism behind the life cycle's stagnation stage. In Butler's model a destination's visitor numbers rise along an S-curve until they approach the limits the environment, infrastructure, and community can sustain, at which point conditions deteriorate, appeal fades, and growth flattens into stagnation. Carrying capacity assessment makes those limits explicit, so monitoring the gap between current use and capacity is how managers anticipate stagnation and intervene to steer toward rejuvenation rather than decline.

Because experience showed that impacts depend more on visitor behaviour, timing, and management than on sheer numbers, and that any single capacity figure embeds contestable value judgements. Frameworks such as Limits of Acceptable Change reframe the question from 'how many visitors' to 'what resource and social conditions are acceptable,' set measurable indicators and standards for those conditions, and trigger management action when standards are breached. They retain the spirit of carrying capacity while making it adaptive and explicit about values.
