In this paper we submit some thoughts on the possible implications of the COVID-19 pandemic for rural people in the countries of the Greater Mekong Subregion (GMS). We base our observations and conclusions on our long-term research experience in the region. The paper focuses on the economics of rural households during this crisis period and its aftermath. We conclude that country differences clearly exist due to their different stages of development. However, while rural households belong to the Corona risk groups, they are also resilient to such a shock. We submit that Governments in the GMS should strengthen policies that conserve the safety-net function of rural villages.

While the expansion of smallholder rubber farming in southwest China has contributed to the local rural economy, it has also had negative environmental consequences. The economics and potential risks of smallholder rubber farming remain unclear due to the lack of quantitative evidence. Based on data collected in a comprehensive survey of 612 smallholder rubber farmers in Xishuangbanna, this paper quantifies economic aspects of rubber farming including land use, inputs and outputs, household income composition, and risks. In particular, we compare differences in these parameters associated with ethnicity and elevation. Our results suggest that rubber has taken over the rural economy in the rubber-planting region of Xishuangbanna, where almost 80% of agricultural land is devoted to rubber. On average, rubber farming provides over 40% of smallholder incomes. While smallholder rubber farming is generally highly profitable, it is also highly vulnerable to price fluctuations. Rubber expansion has also reduced d...

Edible seaweed, a nutrient-rich and sustainable food, has a long dietary history in China. To get a better understanding of the seaweed consumption of consumers in China, this study investigates the quantity and trend of seaweed consumption of Chinese residents and employs a Tobit model to examine the effects of urbanization and dietary knowledge on seaweed consumption among residents. The results show an increasing trend of household seaweed consumption in China, including both seaweeds consumed at home (SAH) and seaweeds consumed away from home (SAFH). Households in urban areas consumed more seaweeds on average than those in rural areas. Urbanization promotes total household seaweed consumption, including SAH and SAFH, whilst dietary knowledge has a significantly positive impact on total household seaweed consumption and SAH. The findings supplement empirical evidence on the seaweed consumption behavior of Chinese residents and have important policy implications for further promoting Chinese seaweeds consumption in the context of urbanization and increasing dietary knowledge.

In China, parents have a choice to either send their children to private migrant schools in urban areas or to keep them in their own county. It is unclear whether the academic differences of students in rural schools and those in private migrant schools is due to the quality of schools, the quality of students/peers, or the ways that peer effects interact with the quality of the school. Using survey data from students with rural residency who attended either migrant schools or rural public schools, we measure how differences in the quality of the types of schools and how the effect of peers differs in high- versus low-quality schools. An instrumental variable approach is used to identify the causality of a student’s peers on his or her academic outcomes and within the context of each of the school venues. The gap in student academic performance is explained by the differences in each student’s peers as and in how peers interact in the schooling environments. The analysis also demonstrates that there is a significant interaction effect between one’s peers and the quality of a student’s school environment. We found that school quality has a complementary effect with peers on student academic performance.

The expansion of cash tree crops, such as natural rubber, in the tropical region of South Asia has resulted in an agricultural transformation from subsistence production to market‐oriented production, implicating the local ecological environment, economy, and household welfare. Based on representative household survey data collected from 611 smallholder rubber farmers in the upper Mekong region, Southwest China, this study examines the impacts of rubber farming on the household dietary diversity of smallholders and explores its potential impact channels through farm production diversity and household income. The results show that rubber expansion has significantly improved household income but negatively affected farm production diversity. While rubber cultivation always has significant and positive effects on dietary diversity, it also indirectly impacts on dietary diversity by the two channels, namely farm production diversity and household income. A set of heterogeneous analyses reveals that rubber cultivation contributes more to household dietary diversity for smallholders having relatively low household wealth or living in a village without a market. While the findings confirm the contribution of rubber cultivation to improving household incomes, food security, and nutrition, the potential risks under the background of falling rubber prices cannot be ignored. The findings of this study not only have important policy implications for improving the food security and nutrition of smallholder rubber farmers but also provide a better understanding of the welfare effects of cash tree crop expansion in tropical regions.
