Good NGOs?
There must be some - they'd source all their materials and personnel locally to boost the economy, encourage locals to devise and deliver practical low tech solutions themselves, add little or nothing in the way of freebie handouts, and above all, get out as soon as the solution started to work and let the locals take pride in work and self help.
They wouldn't drive around famine zones or (more likely) expensive Nairobi restaurants in huge climate criminal's 4X4s with the aircon on and gigantic "my willy's bigger than yours" whip antennas, and act far worse than the caricature Colonials they so love to deride, without any awareness of their irony.
Orrocks! I see the problem. There really aren't any!
