Climate change effects will have unknown impact on human migration says report

摘要

The recently-released Human Development Report 2009 warns that climate change effects are likely to have an as-yet unquantified effect on human migration, and that the ability of humans to adapt will depend on whether the change is gradual or sudden.rnOne knock-on effect is that migration spurs urbanisation, with accompanying challenges. The report notes: 'As is well known, living conditions are often very poor in the slums, with inadequate access to safe water and sanitation and insecure land tenure.'
