Groundwater’s Contribution to Water Security in Africa (Paper by UPGro)

"Groundwater’s Contribution to Water Security in Africa" by UPGro (Unlocking the Potential of Groundwater for the Poor) is a well-researched and very readable background on groundwater's role in water security in Africa.

  1. Dear EB.

    I will peruse your detailed 46pgs papr and comment on same.

    I had a cursory glance, and am appreciative of the details given.

    Meanwhile I want your project researchrs while they are working on hydo-geological details, also to peruse cum study seismology aspects in the African regions you are working on.

    I want you to feel the importance of sub-soil aquifers and their retaining capacity of water resources Etc.

    Water and sub soil regimes contain moisture and greens, and these stratas behave like sponges.

    When water is abundant they retain extra water and in drought / dry times they release water to sustain the terestrial ( on land ) bio-diversity assets.

    Now I would deliberate the main point ie the very nature of sub soil to be moist with greens on surface Etc..

    In this condition if e quakes/ tremors are felt, they are fairly absorbed, due to sub- soil sponge effect.

    Whereas, if they are dry and drier, then the hard nature of soil being rocky in nature would transmit shocks which would be more pronounced, being less absorbed in sub-soil stratas.

    This leads to serious effects in urban areas with high rise buildings Etc.

    Therefore, the respective aquifers are water-conserved and areas are RWH-ed. Water levels are maitained to avert ill effects on e quakes and tremors.

    Will seek your view points regarding African urban scenario. pl.

    Well wishes.

  2. I understand the challenges of access to water resources that African Nations are still faced with in the 21st Century. I also read the background document and the points clearly stated portrays huge untapped potentials.

    Nonetheless, rainfall in Africa is still an untapped resource and in my opinion and across my sphere of research, Africa can be guided towards utilising the over 2500mm MAR in some regions before diving into finite groundwater resources. In the absence of this, unlocking access to poor -and the not so poor is a catastrophe looming when the tragedy of the commons takes stage.

    1. Good said Amali, although still its a palliative; the real solution is the wastewater purification as is the trend in developed countries (e.i. watereuse.org).

      Consider our technology as an integrated solution to SDG#6 letting purify any kind and flow of wastewater into potable with zero emissions to air/soil/water (no brine), 95% minimum efficiency and low operating costs between another sustainable and economical advantages.
