Abstract:

The term vulnerability has been used in a variety of contexts, including climate change impact assessment. This study aimed to set up and evaluate climate change vulnerability indicators (CCVI) of agricultural zones based on exposure, sensitivity, and adaptation capacity to climate change in Ho Chi Minh city. Data from consultations with 10 experts was collected and analysed by the analysis hierarchy process (AHP). The CCVI, which includes 3 primary indicators and 22 secondary indicators, was applied to the agricultural districts in Ho Chi Minh that have been demonstrated to be the most vulnerable to climate change under both current conditions and over a longer timescales under various climate change exposure scenarios. The CCVI was weighted to support the climate change vulnerability assessment and indicate comparatively low or high climate change vulnerability areas. Finally, the areas most needy of further adaptation activities for agriculture in Ho Chi Minh city were identified.
