Further information about this photo, provided by Gaby Service on 25.01.2016:

This photo was taken between the provincial capital where Medair had a base and the project sites in the mountains. Medair staff traveled frequently through this area to reach the field bases (about a 8-10 hour horse ride over high mountains). Also all our supplies had to come on this route, and in the winter the only available transport were donkeys. We were running a big nutrition program in a very mountainous area and big distances between villages with nutrition sites. So Medair had donkey caravans likethis moving all the time, and they looked very similar to the one on the photo, with the same yellow bags. However, the caravan pictured here

There was only one other NGO working in the area, and we could tell by the shape of the bags if the caravans were ours or from the other NGO. They had a food security project and transported fodder into the project area to be distributed to help donkeys and horses survive the winter. So I can tell that this particular caravan was for the other NGO, just looking at the bags. 

So in short – this was not our caravan, but ours looked pretty much likethis and traveled through the same area.
