Water Risks

### Overview  
  
The drought risk indicator is based on [Carrão et al. (2016)](https://doi.org/10.1016/j.gloenvcha.2016.04.012) and was used with minimal alterations. Drought risk was assessed for the period 2000–2014 and is a combination of drought hazard, drought exposure, and drought vulnerability. Higher values indicate higher risk of drought. These values were then converted into risk scores based on the thresholds defined in the methodology. These risk scores range from low (<0.2) to extremely high (>0.8). Values are available per sub-basin (HydroBASIN level 6).   
  
### Methodology  
  
The methodology for calculating the drought risk indicator was based on [Carrão et al. (2016)](https://doi.org/10.1016/j.gloenvcha.2016.04.012). Drought hazard was derived from a non-parametric analysis of historical precipitation deficits at the 0.5 degree resolution. Drought exposure was based on a non-parametric aggregation of gridded indicators of population and livestock densities, crop cover and water stress. Drought vulnerability was computed as the arithmetic composite of high level factors of social, economic and infrastructural indicators, collected at both the national and sub-national levels.

  
  
The hazard, exposure, vulnerability, risk, and no-data mask data available at 5 × 5 arc minute resolution were averaged for each hydrological sub-basin.

  
  
Finally, raw drought risk values were converted to risk scores between 0 and 5, based on quantiles. These scores were placed into categories indicating how high the risk for this indicator is. The thresholds for raw drought risk values and the corresponding risk scores that were used in each category are defined below as Risk Category (Risk Scores): Raw Value Thresholds.
- Low (0-1): 0.0 - 0.2
- Low to medium (1-2): 0.2 - 0.4
- Medium (2-3): 0.4 - 0.6
- Medium to high (3-4): 0.6 - 0.8
- High (4-5): 0.8 - 1.0
