Check occurence of multiple BMZ numbers for each WDPA ID #116

Open melvinhlwong opened 1 year ago

The question: By how many follow-up phases is a protected area financed by KfW? This determines the degree of multiple treatments.

If there are some occurences only, we can simply drop these WDPAs. If there are many, we need to consider Goodman-Bacon Decomposition.

Created a file "mapme.protectedareas/analysis/analysis_00_checkdata_mulitpletreatment.R" to analyze data

We have 388 WDPA IDs @Jo-Schie can you confirm this? I think this is not right. In the threat analysis you wrote that "Our current portfolio database contains 373 areas from a total of 4722 PAs in 16 partnering countries."

I got the data from mapme.protectedareas/output/matching/model_frames/keys_wdpaid_bmz.csv

Results:

out of these we have BMZ number: 1 2 3 Frequency of PA: 350 36 2

Thus, about 90% (350) of PAs have just one BMZ numbers. That does not sound too grave. And we can conser dropping these PAs from our analysis.
