ABSTRACTThe food system’s decreasing ability to deliver food security has led to the emergence of food assistance initiatives. Food assistance is highly contested; as some argue, it is a “failure of the state”, while others regard food assistance to be an “extension of the welfare state”. Either way, research suggests that actors within food assistance are rethinking their role in the food system. In this paper, we study three food assistance initiatives, in the Netherlands, Italy and Ireland, that perform new food assistance practices while embedded in specific institutional contexts, and analyse their potential to transform the food system, drawing on Transformative Social Innovation theory. Building on transition and social innovation theory, this recently developed theory distinguishes different levels within systems, named “shades of change”, that are associated with societal transformation. By exploring these “shades” of change in the analysis, we describe aspects of the initiatives’ novel practices, and in relation to the initiative and institutional relations their motivations and expectations. We compare the three cases and discuss how food assistance practices relate to and change (or do not change) the food system. In particular, we elaborate on how these three food assistance initiatives contribute in various ways to local food and welfare system innovation. In doing so, we offer a novel perspective on food assistance initiatives. We argue that they show dynamics that have the potential for more substantial transformation towards food security over time, by building momentum through “small wins”.

The current world food system gives priority to efficiency and profitability, creating some environmental and inequality problems in the world. In order to re-optimize our food system, we have developed a food system model to adjust the efficiency, profitability, fairness and sustainability of the food system. First of all, we describe the positive and negative effects of food systems optimized for fairness and sustainability, respectively. We have established the index system, and on the basis of the existing data, we use the grey prediction and fitting method to obtain the future data of each index. After that, we divide the previous 12 indicators into benefit category and cost category, and use entropy method to get the weight of indicators that affect benefit and cost each year. We use the “scale factor” method to quantify indicators that are difficult to measure, build models to calculate cost and benefit priorities for changing the world food system, and chart changes that benefit cost ratios in different years.

Until recent decades, labour-intensive subsistence farming was a way of life and livelihood in the hill communities of Uttarakhand, India. However, the nature of agriculture falls far short of the expectations of the main labour force, the rural youth, leading to their mass migration to non-agricultural occupations. The large-scale youth migration has left many hill farming landscapes depopulated and farmlands abandoned. As youth have special stakes in food systems, they must be included in the sustainable transformation of food systems. By doing so, the migration-prone hill region may be transformed into a place where rural youth have more options for work and income. Therefore, the agriculture sector needs to change and develop into a more engaging and youthful workplace. There are opportunities to explore and barriers to be removed. Besides identifying priority research areas on local food systems, in this exploratory research, we investigate opportunities to involve rural young people in the transformation of the food system. We document information by conducting focus group discussion (FGD) meetings in about 100 villages in the Uttarakhand hills, representing all major farming landscapes. This study mainly focuses on improving the production and consumption aspects of local food, which not only benefits the health and wellbeing of local communities but also has many positive economic, social, and environmental effects. In addition, we explore opportunities for reviving mountain agriculture through agri-ecotourism, which is a symbiotic relationship between tourism and agriculture. Making home- or farm stays in agri-ecotourism a subsistence strategy for local youth will contribute to a more prosperous rural economy. Recognising Uttarakhand’s rich culture and heritage while exploring the culinary travel opportunities in homestays will provide opportunities to focus more on traditional food systems, exposing various tangible and intangible aspects of the host region’s food culture to tourists. The findings of this study will aid in identifying specific policy issues for consideration by planners and policymakers at the local and state levels. Additionally, this exploratory study will assist young, motivated researchers in conducting follow-up, in-depth investigations and producing empirical data in their specialised fields.

The European Commission's Farm to Fork (F2F) strategy, under the European Green Deal, acknowledges that innovative techniques, including biotechnology, may play a role in increasing sustainability. At the same time, organic farming will be promoted, and at least 25% of the EU's agricultural land shall be under organic farming by 2030. How can both biotechnology and organic farming be developed and promoted simultaneously to contribute to achieving the Sustainable Development Goals (SDGs)? We illustrate that achieving the SDGs benefits from the inclusion of recent innovations in biotechnology in organic farming. This requires a change in the law. Otherwise, the planned increase of organic production in the F2F strategy may result in less sustainable, not more sustainable, food systems.

Science offers many important contributions to achieving the SDGs, of which we highlight two here: first, science generates the basic inputs for innovations, i.e., policy and institutional innovations (including social and business innovations), as well as technology-based innovations to catalyze, support, and accelerate food system transformation; and second, science scrutinizes actions, i.e., assessing ambitions, targets and actions along pathways towards reaching them, for instance, through quantitative analyses and food system modeling. Seven science-driven innovations are elaborated in this chapter, each with some concrete examples. We stress that policy innovations, institutional innovations, and technology innovations are closely connected and actually need to be pursued in an integrated approach. Without accelerated interdisciplinary food system science, the necessary innovations for a sustainable food system will not be achieved. We note the need for systems innovations rather than only single-issue innovations, and call on the science communities to commit to enhanced collaboration among all relevant different disciplines of sciences for this purpose. Moreover, science is not naïve vis á vis power relations: social sciences explicitly uncover them and must identify options for innovations that help to overcome adverse effects. Food system science and food system policy need a stronger framework for constructive and evidence-based interaction for moving ahead. We call upon governments and UN agencies to initiate a process to explore options – existing as well as new – for a strengthened global science-policy interface for a sustainable food system.

Active revegetation after mining: what is the contribution of peer-reviewed studies?

Background: Meadows are regularly mown in order to provide fodder or litter for livestock and to prevent vegetation succession. However, the time of year at which meadows should be first mown in order to maximize biological diversity remains controversial and may vary with respect to context and focal taxa. We carried out a systematic review and meta-analysis on the effects of delaying the first mowing date upon plants and invertebrates in European meadowlands. Methods: Following a CEE protocol, ISI Web of Science, Science Direct, JSTOR, Google and Google Scholar were searched. We recorded all studies that compared the species richness of plants, or the species richness or abundance of invertebrates, between grassland plots mown at a postponed date (treatment) vs plots mown earlier (control). In order to be included in the meta-analysis, compared plots had to be similar in all management respects, except the date of the first cut that was (mostly experimentally) manipulated. They were also to be located in the same meadow type. Meta-analyses applying Hedges’d statistic were performed. Results: Plant species richness responded differently to the date to which mowing was postponed. Delaying mowing from spring to summer had a positive effect, while delaying either from spring to fall, or from early summer to later in the season had a negative effect. Invertebrates were expected to show a strong response to delayed mowing due to their dependence on sward structure, but only species richness showed a clearly significant positive response. Invertebrate abundance was positively influenced in only a few studies. Conclusions: The present meta-analysis shows that in general delaying the first mowing date in European meadowlands has either positive or neutral effects on plant and invertebrate biodiversity (except for plant species richness when delaying from spring to fall or from early summer to later). Overall, there was also strong between-study heterogeneity, pointing to other major confounding factors, the elucidation of which requires further field experiments with both larger sample sizes and a distinction between taxon-specific and meadow-type-specific responses.

A side effect of the raised consumption of Greek yogurt is the generation of massive amounts of yogurt acid whey (YAW). The dairy industry has tried several methods for handling these quantities, which constitute an environmental problem. Although the protein content of YAW is relatively low, given the huge amounts of produced YAW, the final protein amount in the produced YAW should not be underestimated. Taking into consideration the increased interest for bioactive peptides and the increased demand for dietary proteins, combined with protein and peptides content of YAW, efforts should be made toward reintroducing the latter in the food supply chain. In this context and in view of the prevalent dietary iron deficiency problem, the objective of the present study was the investigation of YAW fractions' effect on Fe bioavailability. With this purpose, an in vitro digest approach, following the INFOGEST protocol, was coupled with the Caco2 cell model. To evaluate whether YAW digest fractions exert positive, negative or neutral effect on Fe bioavailability, they were compared with the ones derived from milk, a well-studied food in this context. Milk and YAW showed the same effectiveness on both Fe bioavailability and the expression of relative genes (DCYTB, DMT1, FPN1, and HEPH). Focusing further on YAW fractions, by comparison with their blank digest control counterparts, it resulted that YAW 3- to 10-kDa digests fraction had a superior effect over the 0- to 3-kDa fraction on Fe-uptake, which was accompanied by a similar effect on the expression of Fe metabolism-related genes (DCYTB, FPN1, and HEPH). Finally, although the 3- to 10-kDa fraction of bovine YAW digests resulted in a nonsignificant increased Fe uptake, compared with the ovine and caprine YAW, the expression of DCYTB and FPN1 genes underlined this difference by showing a similar pattern with statistically significant higher expression of bovine compared with ovine and bovine compared with both ovine and caprine, respectively. The present study deals with the novel concept that YAW may contain factors affecting Fe bioavailability. The results show that it does not exert any negative effect and support the extensive investigation for specific peptides with positive effect as well as that YAW proteins should be further assessed on the prospect that they can be used in human nutrition.

ABSTRACTBackgroundThe imperative for food system transformation is well known, yet to date there has been minimal emphasis on the blue food system [foods sourced from marine and freshwater environments]. Generally, a food systems approach should shift away from linear and move towards more systems thinking to embrace complexity. This paper focuses on a local social innovation project (Plymouth Fish Finger (PFF)) which has pioneered localising the blue food system. This study aimed to elicit how the (policy and practice) system around the PFF can be appraised to optimise social innovation practices for (blue) food system transformation.MethodsExpert elicitation combined with group model building (GMB) to co‐create and validate a ‘Causal Loop Diagram’ (CLD) to visually understand the policy and practice implication and needs of the PFF initiative. Purposive sampling to recruit a range (n = 14 total) of experts representing the different parts of the system. Two ‘mapping’ workshops (one face‐to‐face, one online) facilitated elicitation of expert input into the process to enable establishment of a final synthesised systems map for critique and validation.FindingsHand‐created maps evolved into a validated CLD, containing 49 elements connected by 130 causal links and 5 feedback loops. These loops revealed how demand generation, supply chain capacity, economic viability, trust and product consistency, and infrastructural constraints, reinforce or balance system performance. Six themes emerged: (i) demand generation, (ii) supply chain constraints, (iii) economic viability, (iv) social innovation and trust, (v) nutritional guidance and (vi) unintended consequences. The CLD also enabled interventions to be pinpointed within a system to inform policy/practice actions for change.ConclusionsWe illustrate how systems thinking and expert elicitation approaches have successfully encouraged dynamic dialogue to support the identification of future policy and practice interventions. This demonstrates how social innovation projects can be championed and their powerful potential for catalysing (blue) food system transformation better realised.

Innovations supporting a shift towards more sustainable food systems can be developed within the dominant food system regime or in alternative niches. No study has compared the challenges faced in each context. This paper, based on an analysis of 25 cases of European innovations that support crop diversification, explores the extent to which barriers to crop diversification can be related to the proximity of innovation settings with dominant food systems. Drawing on a qualitative analysis of interviews and participatory brainstorming, we highlight 46 different barriers to crop diversification across the cases, at different levels: production; downstream operations from farm to retailing, marketing and consumers; and contracts and coordination between actors. To characterise the diversity of innovation strategies at food system level, we introduce the concept of “food system innovation settings” combining: (i) the type of innovative practice promoted at farm level; (ii) the type of value chain supporting that innovation; and (iii) the type of agriculture involved (organic or conventional). Through a multiple correspondence analysis, we show different patterns of barriers to crop diversification according to three ideal-types of food system innovation settings: (i) “Changing from within”, where longer rotations are fostered on conventional farms involved in commodity supply chains; (ii) “Building outside”, where crop diversification integrates intercropping on organic farms involved in local supply chains; and (iii) “Playing horizontal”, where actors promote alternative crop diversification strategies—either strictly speaking horizontal at spatial level (e.g. strip cropping) or socially horizontal (arrangement between farmers)–without directly challenging the vertical organisation of dominant value chains. We recommend designing targeted research and policy actions according to the food systems they seek to develop. We then discuss further development of our approach to analyse barriers faced in intermediate and hybrid food system configurations.

The international collaboration network Food Systems Innovation to Nurture Equity and Resilience Globally (Food SINERGY) unites food system experts concerned with the confluence of environmental, geopolitical, economic, and public health stressors that weaken food systems and increase inequalities. In March 2023, Food SINERGY participants from universities, research institutes, food policy advocacy groups, Indigenous networks, farmers’ associations, consumer organizations, social enterprises, and non-governmental organizations from around the world met in Mont Orford, Québec, for a forum to revisit food system structures across local-to-global scales and to identify key junctures for transformation. This article summarizes the network's discussions in the context of the existing literature. Key knowledge contributions include the importance of diversification throughout the food system for cultivating resilience; the value of food sovereignty in promoting equity across scales; the reconciliation between food sovereignty and equitable trade; the need for consonance between policy environments at different scales to enable positive societal actions; the pioneering role of food system innovations that challenge conventional political and economic structures, with emphasis on agroecology; and the need for critical self-reflection around knowledge production and knowledge use to better serve equitable food systems. These discussion outcomes provide insights for actors seeking to transform food systems in support of equity and resilience.

Despite the widespread influence of the burgeoning digital economy on agricultural productivity in recent years, China’s food system confronts numerous challenges. Notably, research exploring the digital economy’s impact on food system resilience remains scarce, and the pivotal role of industrial agglomeration in this context remains unclear. Therefore, this article is based on the panel data of 30 provinces in China from 2011 to 2021, this paper empirically examines the direct effect, the mechanism of action, and the spatial spillover effect of the resilience of a digital economy-enabled food system using a double fixed-effects model, mediated-effects model, and spatial econometric model. The results show the following: (1) The resilience of China’s urban food system shows obvious spatial differences, but the overall trend in improvement requires attention. (2) The development of a digital economy has a facilitating effect on the level of resilience of the food system, and industrial agglomeration induces an intermediary effect. (3) The digital economy has a significant positive spatial spillover effect on the resilience of the food system; i.e., the digital economy can improve the resilience of the food system in the region and the neighboring regions. Accordingly, policy recommendations have been put forward to improve infrastructure construction and promote the development of digital villages; strengthen the construction of industrial agglomerations and promote the enhancement of the quality and efficiency of industries; and promote the development of regional linkages and build a solid foundation for food security.

Covid-19, one of the most critical and widespread global pandemics, has resulted in extraordinary risk corollaries engulfing millions of people's lives and has caused an unprecedented economic downturn while amplifying food insecurity. A systematic review of 132 scientific communications was performed over a 15-year period, using articles from the ScienceDirect and Web of Science databases (2006–2021). In addition, 24 policy briefs, country papers, and publications from the UN, WHO, FAO, and OECD were cited. The aim of this paper is to provide a comprehensive review of existing literature on the adverse effects of the Covid-19 pandemic on agricultural food systems, as well as potential strategies for building robust, resilient, and sustainable food systems to ensure global food security, safety, and endeavors regarding future global emergencies, as well as new research policies while achieving SDG targets. This would fill a research gap while also having long-term implications for health, agricultural, and food resilience policy development in a rapidly changing world. Covid-19 demonstrates how human, animal, and environmental health are all interconnected, emphasizing the need for one health legislation and a paradigm shift in planetary health. Furthermore, it identifies potential mechanisms for rebuilding better systems by shifting priorities toward policy coherence, innovative food system governance, re-engineering market access, and nexus thinking in the food system approach. According to our findings, the COVID-19 posed unavoidable impediments to achieving SDG targets for food security and household poverty.Graphical abstract

The workshop was organized by the CGIAR Research Initiative on Low-Emission Food Systems (MITIGATE+), which is implemented by a large consortium of partners. The Initiative aims to reduce annual global food systems emissions by working closely with key actors in target countries to co-create knowledge that enables them to make evidence-based decisions and address challenges in food systems discourse, policy development, and implementation to reduce greenhouse gas emissions. The Initiative’s partners support the establishment of a multistakeholder platform and a “living lab for people” (LL4P) that will support bottom-up innovation cases to help transform food systems in Nandi county, Kenya, while also reducing greenhouse gas emissions. The workshop was part of a series of stakeholder workshops that aims to help clarify development opportunities, the role of different actors in Nandi county, and their interests. The intention was to bring actors together, invite them to think about a joint vision for food systems in the county, and share perspectives on entry points for initiating system change.
