So you might be wondering why the United Nations World Food Programme needs a geospatial support unit. Let me give you a brief overview,
Basically, they curate and maintain global datasets that they use to model the risk of sudden-onset disasters than might lead to a food security risk. They use this model to send out early warnings to at-risk communities and help with the response when disasters happen.
Of course, there is more to it ...
But I will let Rohini Sampoornam Swaminathan ( The head of the Geospatial Support Unit at the UN World Food Programme) explain it in more detail.

BeforeAfterMap OSM Before-After Maps is an online tool that allows anyone to easily compare how a particular area looked in terms of OpenStreetMap (OSM) data at two different years, side by side, and get a visual insight into mapping contributions over time.
