Social –economic vulnerability (poor infrastructure, lack of insurance system, credit, knowledge, poor management, irigation,ect) Who are vulnerable? - People living along in low deltas and coastal belts. - Migrant and poor labor residents in cities - Ethnic minority, women, children and elderly. The poor are also most at risk because they have little diversity in their income . | Lecture 4 Climate change, Environment issues and Impacts Lam Thi Thu Suu CSRD Sea level rise (m) Land lost (%) Pop. displaced (%) # # 25 # 20 ( mil.) # # 50 # 75 (14 mil. ) Mekong delta as one of three hardest-hit delta regions by climate change worldwide (IPCC 4th Assessment Report, 2007) Vietnam as the top four countries affected by sea level rise Delta supplies more than 53% of the nation’s rice and crop food, 80% of the total fish production, and 75% of fruits for domestic and export.
