Abstract
The concept of carrying capacity has been applied broadly to various biological and social contexts. This article presents a systematic review of the carrying capacity literature as applied to human-occupied environments. The review evaluates underlying approaches and methods and explores the utility and limitations of the concept’s applications. Prominent tools and approaches identified include evaluation index systems, ecological footprint analysis, the Cifuentes method, multi-objective optimization, system dynamics, fuzzy mathematics, and remote sensing and geographical information systems. Our findings indicate that, despite its origins, carrying capacity research is rarely concerned with the survival of human communities; instead, it is often invoked to understand the implications of human population growth and urbanization on living and sufficiency standards. The majority of identified carrying capacity studies did not define a strict upper boundary, demonstrating the utility of carrying capacity as a rhetorical strategy to galvanize action before system degradation eliminates options. The concept of carrying capacity, when applied to human-managed and constructed environments, increasingly reflects socioeconomic factors and quality of life considerations, underscoring subjective social constraints and societal tolerance levels rather than physical limitations on population survival.
