More and more people worldwide live in urban areas, and these areas face many problems, of which a sustainable food provision is one. In this paper we aim to show that a transition towards more sustainable, regionally organized food systems strongly contributes to green, livable cities. The article describes a case study in the Dutch region of Arnhem–Nijmegen. Partners of a network on sustainable food in this region were interviewed on how they expect the food system to develop, and in design studies possible futures are explored. Both the interviews and the designs give support to the idea that indeed sustainable food systems can be developed to contribute to green livable cities. They show that the quality and meaning of existing green areas can be raised; new areas can be added to a public green system, and connections with green surroundings are enforced. They also show that inhabitants or consumers can be stimulated to become so called food citizens, highlighting that the relation of food systems and livable cities is a very close one.

Purpose: Food waste occurs in every stage of the supply chain, but the value-added lost to waste is the highest when consumers waste food. The purpose of this paper is to understand the food waste behaviour of consumers to support policies for minimising food waste. Design/methodology/approach: Using the theory of planned behaviour (TPB) as a theoretical lens, the authors design a questionnaire that incorporates contextual factors to explain food waste behaviour. The authors test two models: base (four constructs of TPB) and extended (four constructs of TPB plus six contextual factors). The authors build partial least squares structural equation models to test the hypotheses. Findings: The data confirm significant relationships between food waste and contextual factors such as motives, financial attitudes, planning routines, food surplus, social relationships and Ramadan. Research limitations/implications: The data comes from an agriculturally resource-constrained country: Qatar. Practical implications: Food waste originating from various causes means more food should flow through the supply chains to reach consumers’ homes. Contextual factors identified in this work increase the explanatory power of the base model by 75 per cent. Social implications: Changing eating habits during certain periods of the year and food surplus have a strong impact on food waste behaviour. Originality/value: A country is considered to be food secure if it can provide its citizens with stable access to sufficient, safe and nutritious food. The findings and conclusions inform and impact upon the development of food waste and food security policies.

Tijdens de HAS Food Experience 2021 voert Marjo Baeten gesprekken over het ontwerpen van duurzame voedselsystemen. In gesprek met de gasten komt aan bod wat hun visie op de uitdagingen in food vandaag de dag is én welke impactvolle, creatieve en ondernemende oplossingen er zijn bedacht zijn.

The HAS professorship Future Food Systems is performing applied research with students and external partners to transform our food system towards a more sustainable state. In this research it is not only a question of what is needed to achieve this, but also how and with whom. The governance of our food system needs rethinking to get the transformative momentum going in a democratic and constructive manner. Building on the professorship’s research agenda and involvement in the transdisciplinary NWA research project, the postdoc will explore collective ownership and inclusive participation as two key governance concepts for food system transformation. This will be done in a participatory manner, by learning from and with innovative bottom-up initiatives and practitioners from the field. By doing so, the postdoc will gain valuable practical insights that can aid to new approaches and (policy) interventions which foster a sustainable and just food system in the Netherlands and beyond. A strong connection between research and education is created via the active research involvement of students from different study programs, supervised by the postdoc (Dr. B. van Helvoirt). The acquired knowledge is embedded in education by the postdoc by incorporating it into HAS study program curricula and courses. In addition, it will contribute to the further professional development of qualitative research skills among HAS students and staff. Through scientific, policy and popular publications, participation in (inter)national conferences and meetings with experts and practitioners, the exposure and network of the postdoc and HAS in the field of food systems and governance will be expanded. This will allow for the setting up of a continuous research effort on this topic within the professorship via follow-up research with knowledge institutes, civic society groups and partners from the professional field.
An important line of research within the Center of Expertise HAN BioCentre is the development of the nematode Caenorhabditis elegans as an animal testing replacement organism. In the context of this, us and our partners in the research line Elegant! (project number. 2014-01-07PRO) developed reliable test protocols, data analysis strategies and new technology, to determine the expected effects of exposure to specific substances using C. elegans. Two types of effects to be investigated were envisaged, namely: i) testing of possible toxicity of substances to humans; and ii) testing for potential health promotion of substances for humans. An important deliverable was to show that the observed effects in the nematode can indeed be translated into effects in humans. With regard to this aspect, partner Preventimed has conducted research in obesity patients during the past year into the effect of a specific cherry extract that was selected as promising on the basis of the study with C. elegans. This research is currently being completed and a scientific publication will have to be written. The Top Up grant is intended to support the publication of the findings from Elegant! and also to help design experimental protocols that enable students to become acquainted with alternative medical testing systems to reduce the use of laboratory animals during laboratory training.
COMBINE staat voor: COmmunity driven Model Based INtelligent systems Engineering. Voorgaande RAAK-mkb projecten Fast&Curious en SMARTcode resulteerden een community van bedrijven en kennisinstellingen rondom HAN tools voor modelgebaseerde ontwikkeling van regelsystemen. De aanvankelijke focus lag hierbij op de prototype fase. Intussen is de focus verschoven naar serieproductie. Er is veel waardering voor de deling van preconcurrentiële kennis en ervaring in de community en de marktgedreven ontwikkeling van de tools, aangestuurd door de community. Diverse vakbladen deden hiervan verslag. De HAN tools richten zich tot op heden op het modelleren van regelalgoritmes. Nu de voordelen van deze technologie door de MKB partners worden herkend en ingezet, ontstaat de wens om vergelijkbare ondersteuning te introduceren voor het modelleren van het te regelen systeem. Een dergelijke aanvulling op de tools completeert de ondersteuning voor een volledige, modelgebaseerde workflow. Dit resulteert in een centrale MKB vraag naar de benodigde kennis en de tools om systeemmodellen snel, goedkoop en met de vereiste kwaliteit te kunnen realiseren en vervolgens optimaal te integreren in het ontwikkelproces. Naast de gewenste uitbreiding van de tools ontstaat er ook vanuit de Agri & Food sector een toenemende vraag naar de in de community beschikbare tools en de gehanteerde samenwerkingsvorm. COMBINE beoogt daarom twee doelen: 1. Het combineren van de sectoren High Tech Systemen & Materialen en Agri & Food op het gebied van modelgebaseerd ontwikkelen 2. Het combineren van nieuwe modelgebaseerde technieken op het gebied van systeemmodellering met bestaande low-cost tools Met de deliverables van COMBINE – tools, ontwikkelproces en preconcurrentiële samenwerking – worden bestaande oplossingen voor het MKB verrijkt op het gebied van systeemmodellen en direct gedeeld in een groeiende community die een breder applicatiegebied bestrijkt.
