GoKawiilResearchers map Africa's water demand at high resolution down to 2.5 arc-minutes
A new study assesses sectoral and subsectoral water demand across Africa for 2010 and 2020, covering municipal use, irrigation, livestock, manufacturing, electricity production and mining. The researchers measure water withdrawal rather than water consumption, and compute most sectors at a 5 arc-minute grid resolution, with municipal and industrial demand calculated at a finer 2.5 arc-minute resolution.
GoKawiil's interpretation of the reporting above, not reported fact.
This fine-grained approach yields up to 144 times more data points per grid cell than studies using the common 0.5-degree resolution, which could allow planners to identify localized water shortages that coarser continental models miss. More granular demand data may help governments and researchers better target infrastructure investment, especially in sectors like irrigation and municipal supply where unmet demand directly affects crop yields and household access to water.
- Study covers six water-use sectors across Africa for 2010 and 2020
- Uses water withdrawal (not consumption) as its core metric, distinguishing it from return flow
- Resolution reaches 2.5 arcmin for municipal/industrial data, far finer than typical 0.5-degree studies
