Comparing and benchmarking land value and property rights across different regions and sectors can be challenging due to the complexity and diversity of land markets and legal systems. Common issues include limited or unreliable data on land transactions, leases, or rights, especially in emerging or informal markets, which may require proxies, assumptions, or expert opinions to fill the gaps or adjust the data. Additionally, there may be differences in definitions, measurements, units, currencies, or time periods of data across regions or sectors which can be addressed by using conversion factors, indices, or adjustments. Finally, variations in the applicability, validity, or accuracy of valuation methods and benchmarks across regions or sectors may necessitate multiple methods or benchmarks to be used or tailored to the specific context. To overcome these challenges it is best to define your objective and scope clearly and realistically and align them with your data sources and methods. Furthermore, collecting and analyzing data systematically and rigorously is essential as well as interpreting and communicating results objectively and transparently while acknowledging any limitations, uncertainties, and sensitivities.
