Determinants of Good Agricultural Practices (GAP) Adoption in the Chili Production System in Northeastern Thailand: A Case of Participatory Approach

抄録

A participatory research approach has been conceptually proposed as an effective method for introducting knowledge-intensive technologies. This approach was adopted for the promotion of Good Agricultural Practice (GAP) in the chili production system in Thailand. However, some farmers still use conventional practices that often result in an overuse of chemicals. This study projected the impact of participation and improved knowledge of farmers, which can encourage the program adoption. Other conventional factors such as farming characteristics were also considered. Research was carried out involving 179 chili farmers both participants and non-participants in the GAP program located in the Northeastern part of Thailand. A treatment effect model was used in the identification of factors affecting the program adoption. Results showed a significant effect on program participation and farmer’s knowledge that was the precursor of adoption. Farmers’ experience in chili production significantly affected adoption. Age was a negative determinant of adoption. The conclusion can be drawn that adoption of knowledge-intensive technologies such as GAP needs an effective approach such as the participatory research program, which can improve farmers’ knowledge and encourage them to adopt innovative technologies. This approach allows farmers to learn from the experience of other farmers.
