Purpose
This study aims to structure research on water resources in the hotel industry, identifying the key areas and research gaps in this field.
Design/methodology/approach
A systematic literature review of water use in the hotel industry has been performed using the Scopus and Web of Science databases. From 515 articles selected between the years 2000 and 2019, a sample of 58 articles was used to structure existing research on this subject.
Findings
Research is classified into four groups: water consumption, water management, impacts of water use and good practices, with different research methods and topics within each one. Existing research gaps and their causes are also discussed. The results show how academic research can help strengthen international methodologies that measure sustainability.
Research limitations/implications
Because of the search process, some publications on water consumption in the hotel industry may have been missed; also book chapters and conference papers were excluded. Furthermore, the authors recognise some subjectivity in the classification of articles.
Originality/value
To the authors’ knowledge, this is the first systematic analysis focussed on water use in the hotel industry. The findings can be used to build a research framework for this area, establishing an approach to cover research gaps and to connect academic research with general methodologies and indicators of sustainability, as well as improving data collection techniques in this field.
We evaluated the feasibility of using aerial photo-based office methods rather than field-collected data to validate Landsat-based change detection products in national parks in Washington State. Landscape change was performed using LandTrendr algorithm. The resulting change patches were labeled in the office using aerial imagery and a random sample of patches was visited in the field by experienced analysts. Comparison of the two labels and associated confidence shows that the magnitude or severity of the change is a strong indicator of whether field assessment is warranted, and that confusion about patches with lower magnitude changes is not always resolved with a field visit. Our work demonstrates that validation of Landsat-derived landscape change patches can be done using office based tools such as aerial imagery, and that such methods provide an adequate validation for most change types, thus reducing the need for expensive field visits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
