My data visualization for Visualizing.org‘s Visualizing Urban Water Challenge.
A view of almost each country’s available freshwater resources, compared to the freshwater withdrawal; water per capita, the percent of urban and rural population, and what percent of them have access to improved drinking water and improved sanitation, and an estimation for urban population growth in 2030 in this context. The data is arranged as a generated water drop, with mugs (representing the population with access to improved drinking water), or baths (for sanitation), which contain as much water as the percent of population who has access to them, for each country.
How to use it:
Select a country in the drop-down menu (they are ordered by continents and alphabetically).
Now the water-drop is generated.
The left side of the mug (or bath if Sanitation button is clicked) represents the rural population, the right side mug (or bath) is the urban population. They are resized according to the urban/rural population percentage for 2010, and also the estimation for 2030 (click play button under Urban Population Growth).
How much of the mug (or bath) is in water – this represents the percentage of population who has access to improved drinking water (or sanitation), what is above, doesn’t.
The freshwater, withdrawal bars compare the quantity of water withdrawn against the total renewable freshwater resources for that country. It corresponds to the water level in the water drop, unless the difference is to big to be viewed well, when that happens the water drop has a bigger frame, indicating there is more water than shown.
The Water per Capita includes the water directly used by a person, and also indirectly used, in agriculture and industrial sectors.
When some data is missing, the indicators show 0, but the drop shows a default value instead.
