Post-survey Likert constructions: an adaptive method for generalizing perceptions of environmental variability

Environmental perceptions are inherently based on an individual's existing knowledge, experiences, and future expectations. Methods for measuring environmental perception, therefore, must capture a range of experiences while also being flexible enough to integrate these experiences into a coherent unit for analysis. Many research topics require cross-cultural comparisons in order to corroborate findings; however, assessments of environmental perception are often place- and context-specific. We propose here post-survey Likert constructions (PSLCs), using semi-structured interviews to construct a five-point scale system from multiple household responses after the completion of interviews. This method is able to capture the natural variability in the population using the respondents' own language and characterizations of phenomena. We applied this method to measure the perceived environmental variability of residents living in a dynamic flooding landscape in the Okavango Delta, Botswana. The PSLC method captures the differences in environmental perception in a location with different settlement and cultural histories, multiple language groups, and different environmental conditions. The method easily transfers to other environments and populations, allowing for potential cross-cultural comparisons of perceived environmental variability. This publication responds to calls for increased transparency in reporting the development, execution, advantages, and disadvantages of methods related to environmental change.
