Figures & data

Figure 1. Expansion of Moria irregular accommodation (Lesvos). The yellow boxes illustrate structural expansions between each year. The Greek government has announced the closure of this structure which will be replaced by a new one capable of hosting 5000 people initially. The satellite imagery belongs to Maxar technologies and was acquired through Google Earth.
