D3.3 Case-independent changing social norms predictive model

The CHORIZO project is dedicated to enhancing our understanding of how social norms influence behaviours related to food waste generation. To effectively address food loss and waste (FLW), one of the goals of the project is focused on developing computer simulations to evaluate the impact of interventions designed to reduce FLW behaviours.
The work that underlies the social models directly builds upon the insights presented in Deliverable 3.1, 'Conceptual framework for behavioural change understanding,’ which establishes a theoretical foundation that unifies the MOA and HUMAT frameworks, laying the groundwork for developing computer simulations.
Deliverable 3.3 ‘Case-independent changing social norms predictive model’ comprises of two social norms models that operate in two different contexts. The establishment diner model is an agent-based simulation examining food consumption in a social context. This model is pertinent to both descriptive and injunctive social norms, and social roles such as client, guest, in-group members (e.g., businessperson). Additionally, it also considers gender roles. The model combines insights from Case Studies 2: Hospitality food waste, 3: Food services food waste, and 4: School food waste and relation with obesity and malnutrition.
The second model, the home cook, is a microsimulation that explores food consumption at home. As the behaviour is private, this model is particularly relevant in the context of injunctive social norms, gender roles and social roles of a parent, housewife/househusband and host. The model integrates insights from Case Studies 1: Household food waste in and off crisis periods and 6: Food waste in relation to date marking and sustainable and smart food packaging.
This document accompanies the developed software, providing a technical description of the models to allow for a comprehensive understanding of the assumptions they are based on and how they work, especially among non-expert programmers.
