Madagascar: Water productivity, total (constant 2015 US$ GDP per cubic meter of total freshwater withdrawal)

Key figures

What the numbers say

In 2022, Madagascar's water productivity, total (constant 2015 US$ GDP per cubic meter of total freshwater withdrawal) rose US$0.04 on 2021 (from US$0.95 to US$0.99).

Across the 30 yearly changes before that (1992 to 2021), the average change was +US$0.02 and a typical year strayed about US$0.03 from that (the standard deviation). This year's change was 0.7 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was US$0.05 in 2003 and the biggest yearly fall was US$0.08 in 2002. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2013 to 2022 the straight-line trend is upward, about US$0.02 a year. A straight line explains 85% of the movement over 10 observed years.

What this measures

Water productivity is calculated as GDP in constant prices divided by annual total water withdrawal.

Limitations: A common perception is that most of the available freshwater resources are visible (on the surfaces of lakes, reservoirs and rivers). However, this visible water represents only a tiny fraction of global freshwater resources, as most of it is stored in aquifers, with the largest stocks stored in solid form in the Antarctic and in Greenland's ice cap. The data on freshwater resources are based on estimates of runoff into rivers and recharge of groundwater. These estimates are based on different sources and refer to different years, so cross-country comparisons should be made with caution.

Regional and income-group figures are computed by the World Bank as a weighted average.
