1 Description

This file includes maps for sub-national WB-ECA indicators. Most maps are given for two spatial divisions: first level administration units (e.g., provinces), and River Basin districts (RBD).

1.2 Deviation from national values and rescaling

1.2.1 Economic water productivity - agricultural

This indicator uses crop growth revenue instead of agricultural added value. Revenues are much higher since they include all costs (unlike profits), thus the results are much higher relative to the national values. However, under the assumption that there is relatively high correlation between value added and revenues in each country, this indicator can teach us the spatial distribution of the agricultural water economic productivity.

1.2.2 Water withdrawal per capita

This data relies on global modeled data, whereas domestic and industrial withdrawals are model inputs (based on gridded GDP and population), and agricultural withdrawals (irrigation) are model outcomes. As such, there were discrepancies beteween the ECA tollbox national value and the calculated national value. In this case, we used a factor (ECA national/calculated national) to rescale the values, so the model data provide only the spatial distribution of withdrawals (e.g., weights).

Rescaled_values = Calculated values * factor

1.3 Excluded Indicators

Indicators’ exclusion is due to the following reasons: Data is not available at the required spatial resolution (groundwater table decline). Modeled data is not representative at the national/sub-national scale (Share of surface/groundwater from water withdrawal, Share of sector water use from water withdrawal). *Mapping exercise requires too complex methodology and can’t be bench-marked to the national ECA toolbox values (available renewable water resource)

3 Outcomes

3.1 Water stress ratio

This indicator shows the freshwater withdrawal as a proportion of available freshwater resources is the ratio between total freshwater withdrawn by major economic sectors and total renewable freshwater resources, after considering environmental water requirements. The threshold values and the range band for this indicator is obtained from Hanasaki et al. (2018). The research article provides a 4-range band based quantitative and qualitative description. This was expanded to a 5-range band description to fit the proposed form of endowment assessment.

## [1] "National Value = 1.0591"

3.2 Exposure of people to water stress

This spatial indicator shows the exposure of the population to water stress, by combining water stress information (overall demand/availability) with population data into a map depiction, showing also subnational information. For this indicator, there are no established range bands available. The range bands which are expressed in quintiles depict the spread of values in the ECA region.

## [1] "National Value = 0.6765"

3.3 Economic water productivity

This indicator shows the water productivity at subnational level, by combining spatially explicit water demand and GDP data (in contrast to the SDG indicator on water productivity above). The range bands which are expressed in quintiles depict the spread of values in the ECA region.

## [1] "National Value = 7.8461"

3.4 Economic water productivity (agricultural sector)

This indicator shows the agricultural water use productivity at subnational level, by combining spatially explicit irrigation water demand and crop revenue (in contrast to the SDG indicator on water productivity above). The range bands which are expressed in quintiles depict the spread of values in the ECA region.

## [1] "National Value = 0.2873"

4 Performance

4.1 Riverine flood risk - population affected

This indicator is defined as the percentage of the population that is expected to be directly affected by riverine flood risk in an average year, while considering flood protections. The indicator is calculated by considering hazard and exposure. Threshold values for the range bands were obtained by assessing population affect by riverine flood risk in all countries around the world and applying quantiles.

## [1] "National Value = 0.0215"

4.2 Riverine flood risk - monetary

This indicator is defined as the direct flood damage experienced by a country as a percentage GDP in an average year, while considering flood protections. The indicator is calculated by considering hazard, exposure, and vulnerability. Threshold values for the range bands were obtained by assessing monetary riverine flood risk in all countries around the world, and deducing risk groups applying quantiles.

## [1] "National Value = 0.0215"

4.3 Drought risk

This indicator specifies to what extent a country is expected to be affected by droughts. The indicator considers the likelihood of the occurrence of a drought, its severance, the population and assets exposed, as well as their vulnerability to droughts. The threshold values and the range bands for the risk indicators presented below were obtained from the risk thresholds in Aqueduct 3.0 (Hofste et al., 2019). # used quintiles #

## [1] "National Value = 3.1241"

5 Architecture

5.1 Per capita dam storage capacity

The thresholds for per capita dam storage capacity are often compared for semi-arid countries where water availability is limited. Developed countries like USA, Australia and fast developing countries like China are associated with high per capita storage (>1500). Low income and developing countries with arid climate are associated with lower per capita storage.

## [1] "National Value = 2112.4911"

5.2 Share of cultivated land under irrigation

The percentage of cultivated land that is irrigated in a country cannot be classified under a ranking system as it depends on the country’s specific hydro-climatology and agriculture crop choice. This indicator is therefore categorized as an informative indicator.

## [1] "National Value = 0.7667"

6 Endowments

6.1 Water withdrawal per capita

The range band for this indicator is based on the global dataset of water withdrawal per capita. Most of the countries with the ECA region lie within the range of 250-1000 m3/person/year. The thresholds are defined based on Ritchie and Roser (2017).

## [1] "National Value = 1222.87"

6.2 Inter-annual variablilty (of water wupply)

The range bands and their thresholds values for this indicator were obtained from the World Resources Institute (WRI) Aqueduct Water Risk. Higher values indicate wider variations in available supply from year to year.

## [1] "National Value = 0.413"

6.3 Seasonal variablilty (of water wupply)

The range bands and their thresholds values for this indicator was obtained from the World Resources Institute (WRI) Aqueduct Water Risk. Higher values indicate wider variations of available supply within a year.

## [1] "National Value = 0.7374"
