Abstract

The objective of the study is to apply Ricardian approach integrated with two-stage Hsiao method using a 9-year panel data to examine the impact of extreme weather events and climate change on the income of agriculture and fishery farmers in the Central and Central Highlands regions of Vietnam in the period 2002-2018. Findings from the study show that extreme weather events and climate change cause an average decline from 0.982% to 17.060% in the income of agriculture and fishery farmers under different climate change scenarios. The drought causes more severe damages to farmer income than the storm. While the precipitation in all seasons creates a positive impact on farmer income, the temperature of the summer-autumn has a strong negative impact. The impact of the temperature on the South Central region is the largest while the North Central is the region least affected by climate change. The levels of damages to agriculture farmers are very high and tends to increase compared to fishery farmers.
