Soil and Land Suitability Analysis

Rotation of rice-shrimp farming is considered as a promising model in adapting to climate change. However, some rice - shrimp households have recently shifted to shrimp monoculture with the expectations of higher profit. Therefore, the current study is aimed at measuring the economic efficiency and investigating the determinants of efficiency gaps for 70 rice-shrimp farmers in An Bien district, Kien Giang province. The study found that the cost share of shrimp farming accounted for 47.87% of total cost, which is lower than that of rice cultivation (53.13%). However, the net profit of shrimp farming was 4.25 times higher than that of rice. The average economic efficiency was 52.1%, which means that the farmer could contract about 47.9% of the total cost without compromising the output. The study also found that educational level and training had positive effects while the distance from field to road system had negative correlations with the economic efficiency.
