Abstract
Thailand is the largest nature rubber exporter in the world. The rubber industry is particularly important for both the national economy and farmers. However, the increasing popularity of monoculture rubber plantation has posed challenges for the sustainable development of rubber industry due to the negative impacts of homogeneous cropping systems. Rubber crop diversity system is expected to alleviate the environment degradation and secure rubber farmers’ income. Nevertheless, the rubber diverse cropping systems adoption is more complicated for most rubber farmers in Thailand. Using the data on rubber farmers which cover 3344 observations from Office of Agricultural Economics in Thailand throughout the period of 2012–2014, this paper investigated the influential factors of rubber crop diversity adoption. The results indicate that rubber farmers are usually lack of management skills, information, and market access in crop diversity adoption. Adequate rainfall and water, household labour, land right certificate, land degradation, the use of organic fertilizer, crop sales channels and irrigation access have positive impacts on the adoption of rubber crop diversity. On the other hand, in the southern region, the hiring of foreign labours, agricultural training, off-farm work, male household heads as well as their age and education level are negatively associated with crop diversity adoption. According to the empirical results, it is necessary for rubber institutions to pay more attention to training programmes and education on rubber farmers’ diverse cropping system management skills. Moreover, rubber sustainable development strategies should offer rubber households additional incentives and financial support to relieve their financial constraints and improve the market accessibility. In addition, it is also necessary to focus on rubber households with poor natural resources and agricultural infrastructure and offer supports for infrastructure, such as irrigation systems, to increase rubber crop diversity adoption in Thailand.
