This study aims at determining if organic tea farming results in higher net income than conventional tea farming in the mountainous areas of Northern Vietnam. Our sample includes 226 traditional and 319 organic tea-producing households in the provinces of Thai Nguyen, Phu Tho, Ha Giang, and Lai Chau. Using a propensity score matching approach, the study finds that the adoption of organic tea production had a positive impact on households’ farm income in the study area. Using different matching algorithms, organic tea adopters earned higher income than did non-adopters, from 1038.8 to 1059.0 thousand Vietnamese Dong (VND) per hectare of cultivation plot. To increase conversion to organic tea farming amongst smallholder farmers, the government and other stakeholders should aim to provide better extension services, which incorporate relevant training to farmers and better access to information on organic tea production, as well as encouraging the commercialization of organic fertilizers. Simultaneously, the Vietnamese government should introduce mechanisms to coordinate production activities and deliver tea products to processing and/or marketing facilities.

The Impact

While the aging of agricultural labor force and its impact on agricultural production have been attracting extensive attention, little is known about the relationship between aging of agricultural labor force and technical efficiency in tea production. Using the stochastic frontier analysis and cross-sectional survey data covering 241 tea-producing farmers in Meitan County in China, this study attempts to investigate the impact of aging of tea-producing farmers on technical efficiency in tea production in the mountainous areas of southwestern China. The results show that the average technical efficiency in tea production is 0.581, implying a great room for improving technical efficiency in tea production in Meitan County. While there might exist an inverted U-shaped relationship between farmers’ age and technical efficiency, the aging of tea-producing farmers would exert negative impact on technical efficiency in tea production. In addition, rural–urban migration experience, number of household laborers, distance from home to village committee, and township location are also significantly related with technical efficiency. The findings in this study are proved to be robust. Hence, several policy implications for meeting the challenges from aging of agricultural labor force and improving technical efficiency in tea production in the mountainous areas of southwestern China are also discussed.

The Impact

Despite the economic and food security importance of the Kazakh wheat sector, current statistics suggest a yield gap between actual and potential yields. In view of this, farmers, stakeholders and the government are looking for agricultural technologies to increase the output. To this end, adoption of certified seeds is being promoted. The reasoning is that certified seed is produced from seed of known genetic origin and genetic purity, in a controlled and tested manner, processed and declared in accordance with the Law on Seeds and thus, could aid in producing maximum obtainable output. Unfortunately, little is known on whether this could affect wheat production and technical efficiency more than the conventional seed as such a subject has never benefitted from empirical analysis. To begin to fill this research gap, data from smallholder farms in Kazakhstan is used to evaluate the impact of adoption on technical efficiency by applying the stochastic production frontier. Results indicate that adoption of certified seed has productivity effects. Precisely, adopters are 20% more efficient than their counterparts. To a large extent, this is attributable to the quality of seeds used. Therefore, our study demonstrates the importance of certified seed adoption and accentuates the role governments can play in ensuring seed quality for enhanced technical efficiency.
