Hazard Analysis Method
is a factor of climate change characterized by changes in rainfall
patterns. To analyze the availability of water, then the model developed
in Geographical Information System (GIS). The required data are slope,
rock data and rain water absorption as the trigger of decreasing of
water availability. Then the data is analyzed using GIS and calculated
by approach quantitatively to obtain hazard map.
Vulnerability Analysis
Method
Vulnerability is defined as a function of the nature, magnitude and rate
of climate change as the degree of variation of the affected system. Its
sensitivity and adaptability are determined through criteria of
significant levels of indicator and hazard relationships. The water
availability vulnerability indicator can be seen in Table 3.
