Abstract— The aim of the present research is to enhance food security and sustainability in developed countries through providing a simulation tool for supporting the impact assessment of interventionary policies for the support of smallholdings’ farming. To this effect, we first discuss the role of small farms towards ensuring food security and sustainability in the developed world. Following, the System Dynamics methodology is employed to explore the effect of interventions on the diffusion of small farms’ cultivated commodities to the specific Greek food market. Following, a simulation modelling tool is developed that specifically captures four external factors affecting the adoption rate of the refereed agrifood products, namely: (i) consumers’ environmental awareness, (ii) social implications, (iii) economic incentives, and (iv) health and nutrition consciousness. The simulation results suggest that policy interventions that could play a critical role in ensuring food security and sustainable development in developed nations should mainly focus on the increase of advertising expenditure in promoting small-scale farming and locally cultivated products, on consumers’ training and education, and on subsidies of investments in smallholdings.
