Although every country has estimated the losses caused by
coffee rust, during and after the epidemics, the estimates obtained
are uncertain and difficult to compare between countries.
This can be attributed to: (1) inaccurate assessments of
the coffee rust intensity at country level (2) the different
methods used for assessing coffee rust incidence in the region
(3) the lack of harvest forecasts for some countries (4) a lack of
understanding of the losses that coffee rust can cause in relation
to the assessed attack intensities.
