Smallholder participation in the land rental market in a mountainous region of Southern China: Impact of population aging, land tenure security and ethnicity

- Population aging can foster the advancement of the rural land rental market by transferring land from older to younger farmers.
- The availability of a land tenure certificate increases farmers' participation in the land rental market by improving land tenure security.
- Ethnic minority groups are significantly less likely to rent out land.
- Altitude of household location negatively impacts on renting out land.

Rural land rental markets in China play an increasingly important role in the transformation of the agricultural sector. This study focuses on the rural land rental market in the Xishuangbanna Dai Autonomous Prefecture in Southern China, a mountainous region, where rapid changes in land use have taken place with the transition from traditional agriculture and a tropical rainforest to rubber monoculture. Notably, we assess the impacts of population aging, land tenure security, and ethnicity on the participation of smallholders in the land rental market. The analysis suggests that a higher proportion of older people in a household increases the likelihood of renting out land and reduces the probability of renting in land, implying that population aging fosters land rental market development by transferring land from older to younger farmers. We also confirm that the availability of a land tenure certificate has a significant and positive impact on the renting out of land. Furthermore, ethnic minority groups are less likely to rent out land, indicating that land rental markets are ethnic sensitive. Additionally, specialization in rubber farming, household wealth and the altitude of household location also influence participation in the land rental market.
