Impact of cash crop cultivation on household income and migration decisions: Evidence from low-income regions in China

This study examines the impact of cash crop cultivation on household income and migration decisions, using survey data collected from low-income regions in China. Given farmers decide themselves whether to cultivate cash crops, an endogenous treatment regression model that accounts for potential selection bias issue is used to analyze the data. The empirical results show that cash crop cultivation exerts a positive and statistically significant impact on household income, but it does not affect household migration decisions significantly. The disaggregated analyses reveal that cash crop cultivation significantly increases farm income but decreases off-farm income.

Distribution and diversity of benthic macroinvertebrate fauna in three repeated operating ages of the blood cockle Anadara granosa cultivation in Bandon Bay,Suratthani Province,Southern Thailand

The diversity, distribution and species richness of benthic macroinvertebrate fauna as well as benthic environments were examined in the blood cockle Anadara granosa cultivations at Ban Don Bay, Suratthani Province, Southern Thailand during the summer season of April and rainy season of October in 2017. The cockle cultivations of three repeated operating ages (<5 years: S1; 5–10 years: S2; more than 10 years: S3) were selected for the study, and the sampling sites were allocated at the centre of the farm. Results indicated that there were significant differences in species number, individual number and evenness index of benthic macroinvertebrate fauna found in the two sampling seasons (p < .05) and significant differences in individual number and evenness index were found among the sampling sites (p < .05). Significant differences in pH, total phosphorus levels, sulphide levels and organic matter of sediment were found between the sampling seasons (p < .05) and differences in total nitrogen level, organic matter and clay content were found among the sampling sites (p < .05). Among the independent variables analysed, correlation analysis showed no relationship between diversity index, species richness index and evenness index and the abiotic variables (p < .05). The results of the present study suggest that the distribution and diversity variations of the benthic macroinvertebrates community fauna are not affected by all sediment parameters in various repeated cultivation of the blood cockle Anadara granosa in Bandon Bay, Suratthani Province.
