Introduction: Effective communication among agricultural stakeholders is the part and parcel of sustainable agricultural development. The study investigated farmers' exposure to communication media in receiving agriculture extension and rural advisory services (AERAS) for strengthening sustainable agricultural development. Materials and Methods: The blended method research was conducted in Bangladesh employing both qualitative and quantitative approaches with 390 selected respondents utilizing structured questionnaire during 2022¿2023. Statistical package for social science (SPSS) version 29, along with appropriate scales and scoring techniques were utilized to analyse the data. Results: Findings indicated that most (94.6%) of the respondents get low to medium exposure to communication media, but majority (75.4%) of them were interested in contacting extension and advisory services without payment (73.6%). A significant portion (70.3%) of the participants perceived that, services delivered by extension officers facilitate farm sustainability. It was also found that respondents were mostly exposed to personal media ((Formula presented.) = 377.4) whereas less exposed to mass media ((Formula presented.) = 177.8) for desired services. Moreover, knowledge, proximity to office, access to extension services, organizational participation, innovativeness, training exposure were identified as influential factors increasing the extent of communication exposure. Conclusion: The results can assist concern departments as well as policymakers to update the curriculum, principles, or module for incorporating effective communication at farm level and modifying the diffusion of innovation systems for farm sustainability.

The present study utilizes a coupled simulation-optimization (S-O) methodology to develop a multi-objective management strategy for a coastal aquifer system. The aim of the multi-objective management model is to maximize pumping from freshwater wells (FWs) and minimize pumping from the barrier wells (BWs), while keeping salinity concentration in the aquifer within pre-specified limits (optimization constraint). To achieve computational feasibility of the management model, the numerical simulation model is substituted by the relatively new Gaussian Process Regression (GPR) metamodels. The GPR models are used to approximate coastal aquifer responses to variable transient pumping patterns from FWs and BWs. Prediction capabilities of the developed GPR metamodels are quantified using standard statistical parameters. Once trained and validated, the GPR metamodels are coupled to a multi-objective genetic algorithm optimization model and used to prescribe optimal groundwater pumping patterns. The outcomes of this study establishes the potential applicability of the GPR metamodel-based S-O model for developing sustainable coastal groundwater management strategies, which can utilize accurate and efficient prediction of management strategy impacts on the saltwater intrusion (SI) process when the optimal management policy development is based on the trained metamodel predictions. Once implemented, the developed strategy can help in controlling SI in coastal aquifer systems.
