5.2 Exposure Indicators
Affected Production Areas, affected farmers, damaged farmer equipment/houses/infrastructure, and frequency of
typhoons are the chosen exposure indicators. The first exposure indicator refers to the extent of affected agricultural
areas during the typhoon Santi. From the damage reports provided by the Agriculture Office, data were obtained by
dividing the affected area size by the total agricultural area size in each barangay. The second exposure indicatorrefers to the number of farmers affected during typhoon Santi. To serve as basis of data, the number of farmers
affected in each barangay from the damage reports was divided by the total number of farmers in the area. The third
exposure indicator refers to the extent of typhoon damage on the farm houses, equipment, and post-harvest structures
when Santi hit the city. Since the damage reports of Typhoon Santi had no data on these pieces of information, the
respondents assigned in the affected barangays were asked to give their perceived ratings. The fourth indicator for
exposure refers to the frequency of typhoons affecting Mabalacat City. The data for this indicator may be obtained
from the number of 150-kph typhoons in 3 years. Mabalacat City was struck by major typhoons in the last three
years, and it was the past year’s two typhoons, Maring and Santi, that caused the most destruction so far.
