Agriculture extension and advisory services (AEAS) are integral to smart agricultural systems and play a pivotal role in supporting sustainable agricultural development. The study aimed to assess the role of AEAS in strengthening climate-smart coastal farming system to enhance coastal agricultural sustainability. A mixed-methods study was conducted in the southwestern coastal region of Bangladesh in 2023, which involved administering a structured questionnaire and conducing face-to-face interviews with 390 farmers. Perceived role index (PRI) was employed to assess the potential role of AEAS. To forecast the perceived role outcomes, the machine learning model was undertaken by utilizing suitable algorithms. Additionally, feature importance was calculated to underpin the significant factors of perceived role outcomes. The findings showed that coastal farming communities held a comprehensive understanding of the role of AEAS. Key roles included diffusion of agricultural innovations, acting as a bridge between farmers and research organizations, using demonstration techniques to educate farmers, training farmers on food storage, processing, and utilization, and promoting awareness and adoption of best practices. The machine learning model exposed a significant relationship between farmers’ socio-economic characteristics and their perception behavior. The results identified that factors like innovativeness, awareness, training exposure, access to AEAS, and access to information significantly influenced how farmers perceived the efficacy of AEAS in promoting a smart coastal farming system. However, farmers confronted multiple constraints in receiving demand-driven services and maintaining coastal farm sustainability. These insights can guide concerned authorities and policy-makers in providing AEAS for the purpose of strengthening climate-smart coastal farming system, particularly with a special focus on capacity building programs and machine learning application. Moreover, the outcomes of this study can assist the authorities of similar coastal systems throughout the world to initiate potential strategies for enhancing region-specific agricultural sustainability.
