Environmental degradation caused/exacerbated by the
harvesting of firewood/fodder/shelter materials by concentrated displaced
populations may be of concern to host governments, increase political pressures
and cause tensions with hosts, as well as force increased competition for
scarce biomass resources between livestock grazing and access to firewood.
Tensions may also arise over property rights. Such tensions are likely to increase
over time and can lead to retribution/attacks on firewood collectors/displaced
communities. Poorly designed shelters/cooking structures also increase the risk
of house fires.
