Vulnerability
Rating
It is difficult to determine the direct and indirect costs associated with droughts because of the
broad impacts of drought. This analysis only took into consideration the crop loss data and
public water suppliers with drought vulnerability. Thus, there may be more accurate documented
in regional and local mitigation plans and direct costs associated with droughts.
Summary
The vulnerability to drought for the planning area is centered on transportation nodes, parking
lots, utility poles and structural integrity. Individual homes are vulnerable to foundation cracks
and impairment. Water supply in the Region could be affected as the Kansas and Missouri
Rivers are main sources of potable water and when their levels go down, the population, crops,
and livestock are affected. Loss estimates are too varied to estimate as the loss is dependent
on the degree of the drought and the length of time it is within the area.
