Climate change affects agricultural systems worldwide, including Thailand, and may lead to reduced crop yields, impacting food security. Bambara groundnut is a crop with the potential to adapt to changing environments and can thrive in areas with limited resources.

This research aims to study the impact of climate change on Bambara groundnut yields in Thailand using the DSSAT (Decision Support System for Agrotechnology Transfer) model, an important tool for predicting plant growth under various environmental conditions.

• Methodology: Utilizes climate data, soil composition, and genetic information of Bambara groundnut to simulate and analyze yield trends under future climate scenarios.
• Study Areas: Four locations in Thailand were selected: Songkhla, Lampang, Yasothon, and Saraburi.
• Model: The CSM-CROPGRO-Bambara groundnut model was used to assess the impact of changing temperature and rainfall.

The results of this study are expected to provide farmers and researchers with valuable information for planning cultivation and managing production in response to climate change. Additionally, the findings can help formulate policy guidelines to promote the cultivation of climate-resilient crops and support the country's food security.
