Sergio,
after exchanging with Andrew on what we both see on the screen, I realize that
looking at my screen with a certain angle, contrasts where better to see paths
but the colors of certains objects are affected. In this image, with a certain
angle, trees contrast is particularly exegarated and make them look as black
spots.
On the top left corner of the place I now see what looks to be a well. Pierre

Wells are an important information to provide. But the Bing Imagery shows
exactly what I was talking about before. If we look in the streets around, we
see various water pools that could be left after heayv rain.
To my point of view, we cannot conclude from this imagery that there is a well.
I do not see a structure that would confirm a well in the midlle of the place.
It is not easy to spot these from aerial imagery. For the Mali Activation,
north of Mali early 2013, we could find wells with traces like a propeller
around the well. This is done by using livestock moving around to lift the
water out of the well. Pierre

If it's useful:
-Example of recently constructed well in Didieni/Mali (mounts of debris around,
walls don't rise above (redundant redundancy) the
ground):http://appropriateprojects.com/node/1022
-What seems new wells in Kayes, too (debris seen, walls not seen; seems square
hole, possibly on the going of digging at the moment of satellite
image):http://www.openstreetmap.org/edit?editor=id&%20#map=20/14.44191/-11.46058
