Concise description:

The Drought Vulnerability Index (DVI) can be applied locally or spatially and with different aggregation levels of the input data. The intermediate components can be evaluated independently, allowing comprehensive interpretation of the strengths and weaknesses of each system. The sequential steps taken for the quantification of the DVI are: (a) select variables that are relevant; (b) normalize the variable values with respect to some common baseline; (c) combine the sub-component variables within each category by weighted averages; and (d) quantify DVI as the weighted average of the components. The scores of the DVI range on a scale of 0 to 1, with the total being generated as the average of each component. Each component of the DVI can be viewed as a dimension. Before calculating the overall DVI, an indicator for each of the dimensions needs to be computed. The four dimensions were named as Renewable Natural Capital, Economic Capacity, Human and Civic Recourses and Infrastructure and Technology. All of these categories contain multiple indicators and were aggregated using equal weights.
