ASSESSING ON THE ECONOMIC EFFICIENCY OF THE CLIMATE CHANGE ADAPTION MODELS IN TRA VINH: THE CROP CONVERSION MODEL

Abstract

According to the survey of 162 farm households in Tra Vinh province, this article compares and evalutes the economic efficiency of the crop conversion model (from rice to vegetable). The results show that the incomes of these farm households were 3 times higher than those of rice farm households, approximately 5.7 million VND/0.25 acre /year. In addition, the regression analysis was applied in this study to identify and quantify the factors influencing the economic efficiency of the conversion model. The results confirm the interaction between vegetable crops, rice – vegetable rotational crops, labor cost, age and the ethnicity of householders. In particular, the households’ awareness of climate change has a positive impact on the economic efficiency of the model. Finally, the research suggests some solutions to the improvement of the economic efficiency of the crop conversion model which adapts to climate change.
