The study used the Ricardian approach to examine the economic impact of climate
change on crop production in Mekong Delta, Vietnam. Net farm revenue is regressed against
various explanatory variables, including climate, soil, inundation, irrigation and other socioeconomic variables to examine their influence on variability on net farm revenues. The findings
show that net farm revenues are affected negatively by increasing in temperature and positively
by increasing in precipitation. Under selected climate scenarios in Vietnam, the study predicted
that crop net revenue are expected to fall approximately VND 500 billion in 2050; and by VND
670 to 1,300 billion by the year 2100.
