For indicator 8C, LANDex uses the Transparency International Corruption Perceptions Index (CPI).
The Corruption Perceptions Index (CPI) is the most widely used metric of corruption in the world and is published annually by Transparency International. The index ranks 180 countries by their perceived levels of corruption in the public sector, as determined by expert assessments and businesspeople surveys. The types of corruption covered by the CPI are known to directly distort and affect outcomes in the land sector, which is why it is deemed an appropriate proxy for land corruption in the absence of other more specific data. The assessment provided by the CPI can be complemented by focus group discussions to better understand how corruption specifically manifests in land governance.
In LANDex, the Corruptions Perceptions Index (CPI) is used as a general indication of the presence of corruption in the public sector as a proxy for the likelihood that corruption is also affecting processes of land governance and administration. The CPI scores for each country are pulled into LANDex and used on the 0-100 scale. More information about the CPI and country scores are available on the Transparency International website, linked above.
