That evidence suggests that:
► Increased migration to Europe as a direct result of environmental change is unlikely.
► Those affected by environmental change are more likely to migrate to urban areas where economic opportunities are greater but where there are increased risks of negative climate or environmental change.
► Some populations affected by environmental change may find it difficult to move (and may become, in effect, trapped) even though migration is their best strategy to improve their life chances.
► The increased risk of conflict as a result of environmental change is unproven. In fact, the reverse may be the case (where conflict over scarce resources could be increased by an inability to migrate).
Although the report is a policy brief and is designed to help plan for the future, the above points strike me as a realistic set of testable hypotheses that researchers should be working on, even as policy-planners are thinking of defensive strategies.
