My parents went to a couple they know, which are doing developmental help in Mozambique. The man works for a foundation that funds well digging for local tribes.
They dont haul in a big drill rig, but pay three local men a double wage to dig 10 to 15 yard into hard red soil, into rock bottom untill they hit water.
They stop digging only when the water forces them to. If the water doesnt flow in quick enough to stop them from throwing the bucket aside and taking on the pick and shovel, the well isnt deep enough. Then they line it with locally baked clay bricks, masoned with locally dug sand, only the cement, as well as the manual pump, are purchased. All other labor and materials involved, are sourced locally, so the maximum amount of funds are INVESTED INTO the local economy !!
The foundations objective is deeper than just plain old philantropy: They want to give the local economy a boost by purchasing goods and services from the locals with foreign capital, to build public provisions which raises the standard of living. Just throwing foreign capital into countries doesnt build their economy, it just destroys it. Building 3rd world economies takes time, and you have to start at the basis, just like they did in the Western world 200 years ago.
To help the locals remind that "grey bearded white man" doesnt stay forever, and that they should keep their focus on self support, not holding their hand up, the deal includes that the local villagers have to provide the three well diggers with food for the time they are in the village. The tricky part of developmental help, is that people may become totally depending on help, which makes it impossible to use the limited funds of the foundation to help other villages in the country too.
Digging such a well can take up to 8 weeks of digging. Hard hats are provided to the workers, but they refuse to use them because they cant bend over their shovel in a just over 2 feet wide well, and also wear a hard hat.
So far, nobody was injured by a pebble falling all the way down.
Because the couple is aged (the man was a construction site manager and went for a couple of years, AFTER his retirement) they came back to Holland last month.
