<p>Given the challenges associated with prolonged monoculture rubber cultivation and the volatility of rubber prices, rubber crop diversification has been proposed to improve the livelihoods of rubber farmers, particularly those facing poverty and food insecurity.

摘要

Given the challenges associated with prolonged monoculture rubber cultivation and the volatility of rubber prices, rubber crop diversification has been proposed to improve the livelihoods of rubber farmers, particularly those facing poverty and food insecurity. However, the adoption of such practices remains limited in Thailand. While crop diversification on rubber farms significantly enhances household food availability, its specific effects on food expenditure remain underexplored. This study examines how crop diversification adoption influences the level and structure of rubber farmers’ food expenditure. Using national household-level data collected from a stratified random sample of 1552 households between 2012 and 2014, and applying propensity score matching, the findings indicate that rubber crop diversity has a statistically significant positive effect on food expenditure, increasing annual per capita food expenditure by 1362–1418 baht. Additionally, rubber crop diversity promotes self-produced food consumption by 399–506 baht per person annually, thereby enhancing dietary resilience and food security for farmers. These findings provide a more comprehensive understanding of rubber crop diversity and the empirical support for implementing crop diversity policies to ensure the long-term sustainable growth of Thailand’s rubber industry.
