29 pages, Agent-based models are important tools for simulating farmers’ behaviour in response to changing environmental, economic or institutional conditions and policies. This article introduces an agent-based modelling approach that combines behavioural factors with standard bio-economic modelling of agricultural production. More specifically, our framework integrates the cumulative prospect theory and social interactions with constrained optimisation decisions in agricultural production. We apply our modelling approach to an exemplary bio-economic model on the assessment of weed control decisions. Results show the effects of heterogeneous farm decision-making and social networks on mechanical weed control and herbicide use. This framework provides a generic and conceptually sound approach to improve the scope for representing farmers’ decision-making and allows the simulation of their decisions and recent advances in behavioural economics to be aligned with existing bio-economic models of agricultural systems.
11pgs, Taylor and Francis Online, The field of research on agricultural and rural extension and education, also referred to as advisory services and intermediaries, has always engaged with different aspects of the spaces in which agricultural producers (farmers, growers, ranchers) are situated and operate. In this editorial, I will reflect on the elements and environments which jointly constitute and shape the farm (Darnhofer 2020) and their connection with extension and advisory services in the digital age, opening up new digital and virtual spaces. Extension and advisory services receive ample consideration in current debates on digitalization and digital transformation of the agrifood sector, and are an important focus of attention for agriculture and food systems research, practice and policy (Ehlers, Huber, and Finger 2021; Ingram and Maye 2020; Klerkx 2020). In what follows, I will elaborate on some digital and virtual spaces as sites of extension and advisory services research, to progress the field of study for which The Journal of Agricultural Education and Extension serves as a publication outlet.
