*3.2. Identification of Sources*

According to Green et al. [93], this stage comprises searching electronic databases, references of known articles and authoritative texts, including expert recommendations and unpublished research. Here, we conducted a search in PubMed, a major public health database, and Web of Science, an interdisciplinary research database. We also handsearched expert recommended scientific and gray literature in Google and Google Scholar which could elude our search parameters due to different indexing in research databases. The inclusion of gray literature was necessary, as research on land tenure security and health linkages are scanty and mostly talked about in policy briefs and organizational reports such as the World Health Organization, UN-Habitat, and Global Land Outlook.
