### (a) Secondary data (within '855303_data' folder)
- Secondary data is stored in six data sheets in comma-separated values (.csv) format. Names of the sheets and data contained within are as follows:
    + *n4s_hh* : Household demographic and attributes.
    + *n4s_ids* : All corresponding IDs, including the IDs from the original source datasets, to help link between csv files.
    + *n4s_ls* : Detailed information on extent, proportion and area of the different land covers and associated resource tenure systems in each settlement.
    + *n4s_lvl* : Household livelihood sources.
    + *n4s_rts* : Settlement resource tenure systems.
    + *n4s_setts* : Settlement social ecological context.

### (b) Accompanying documents (within '855303_documentation' folder)
- The variable descriptions are provided as a CSV document and the rest of the accompanying documents are in PDF format. A brief description of each document (name in parentheses) is provided below:
    + **Ethics approval letter** (*n4s_ethics_approval_letter*): A PDF document confirming the ethical approval of using secondary data in the Nature4SDGs project by the GGS Research Ethics Panel (1 pages).
    + **Project information sheet** (*n4s_information_sheet*): A PDF document providing background information on the project, the research objectives and approach (2 pages).
    + **Methods summary** (*n4s_methods_summary*): A PDF file including a description of the data sources, an overview of how these feed into each component of the integrated dataset, and a description of the methods used to compile the data in each component of the datasets (37 pages).
    + **Variable descriptions** (*n4s_variable_names*): An Excel file summarizing all variables in the data files, including their long and short names, type, and a description (1 sheet).
    + **Website materials** (*n4s_website_materials*): A PDF archive of all website materials (9 pages).
