Health target is questionable. Sure head loading isn’t wild but ergonomic implications of 20kg sloshing packs arent either. This statement obviously comes from Grief and should say so?

Does it have emergency relief as a target user?

CTI Ewing Ginder: Target region is Sub-saharan Africa? Or is there a “global” data option?

Target region for the CTI Ewing Grinder: there is no specific target country per the individual product report, but Subsaharan Africa could be listed as the target region in the comparison view (as this is where the website says they are meant to have impact).

Wouldn’t the energy requirement be “human power”?
