3.4. Environmental Change in Refugee Affected Areas: Research Needs and Future Directions (R. Black, University of Sussex-Brighton)
The principal issues raised included: (i) the quality of
existing data on environmental indicators; (ii) key issues in determining
responses to mass displacement (limits imposed by time constraints and
settlement size); and (iii) the validity of current hypotheses (how do we
estimate population: resource ratios and regulatory mechanisms). The following
conclusions were drawn:
First, on the basis of one or more local case
studies, it should be possible to identify both detailed evidence of at least
short-term environmental change, and the role of social, economic and
organisational factors linked to the presence of refugees and refugee assistance
programmes in influencing environmental strategies and sustainability. Specific
questions might include whether increased population density resulting from the
refugees presence has placed excessive pressure on resource management
systems, and whether refugees act differently in terms of resource management
from local populations, beyond the impact of population density alone;
A second question relates to the longer-term impact of refugees
on the environment, and specially the nature of any environmental recovery after
refugees return to their home country. Such an analysis is not easy, and would
need to be placed in the context of other social, economic, political and
environmental processes occurring in the region, especially where the region has
been subject to medium-term cycles of environmental or economic change;
A third area of potential research interest concerns the
opportunity for a more wide-ranging study of vegetational change in
refugee-affected areas bases on analysis of imagery derived from satellite
remote sensing or air photographs. Building on climatic, vegetational and other
data available through the UNEP/GRID database, it would be possible to establish
time series data for a number of individual refugee-affected areas over much of
the
1980s.
