The analysis required for revenue sources is mostly descriptive.This can include the following:

• Rank the top 5-10 sources of revenue generated by biodiversity and ecosystem services (or renewable natural resources).
• For the top sources, calculate the ratio of revenues to expenditures in that sector if the data is available.
• Calculate the total revenues produced and group it according to sectors or as appropriate.
• Identify areas with low revenues, but high revenue generation potential (uncaptured user pays opportunities), or where the sector has significant impact (mining, energy), but fees (polluter pays) are not well captured.
