Food and land system transformations under different societal perspectives on sustainable development

Abstract The future of food and land systems is crucial for achieving multiple UN Sustainable Development Goals, given their essential role in providing adequate nutrition and their significant impact on Earth system processes. Despite widespread consensus on the need for transformation, discussed strategies vary widely, from technology-driven to sufficiency-focused approaches, emphasizing different agents of change and policy mixes. This study assesses the implications of a new generation of target-seeking scenarios incorporating such diverse sustainability perspectives. We apply two integrated assessment models to explore food and land futures under three whole-economy Sustainable Development Pathways (SDPs): Economy-driven Innovation, Resilient Communities, and Managing the Global Commons. Our assessment shows that all SDPs align sufficient food supply with progress towards planetary integrity, halting biodiversity loss, mitigating adverse impacts from irrigation, and significantly reducing nitrogen pollution. While all pathways comply with the Paris climate target, they diverge in the timing of climate mitigation efforts and focus on different greenhouse gases and emission sources. The Economy-driven Innovation pathway rapidly achieves net-negative CO2 emissions from the land system, whereas Resilient Communities and Managing the Global Commons significantly decrease agricultural non-CO2 emissions. Moreover, sustainability interventions attenuate trade-offs associated with narrowly focused mitigation pathways and reduce reliance on carbon dioxide removal strategies like re/afforestation and bioenergy with carbon capture and storage.

Sustainable Marketing of Agro-Tourism: The Socio-cultural Perspective

Agricultural tourism has emerged as a niche tourism phenomenon and its demand has soared across the globe. This paper focuses on the socio-cultural sustainability of agro-tourism. Key socio-cultural dimensions, social capital and authenticity, are examined based on a purposeful sample of spatially dispersed farms in the US. The study results illustrate that agrotourism holds tremendous potential to strengthen and promote local food systems by promoting traditional ways of farming, particularly objective and negotiated dimensions of authenticity, social cohesion, trust and reciprocity. Marketing strategies promoting socio-cultural consumption of agro-tourism are suggested.

From Sustainable Agriculture to Sustainable Agrifood Systems: A Comparative Review of Alternative Models

This paper reviews, compares, and critically evaluates two broad groups of sustainable agriculture models: “sustainable agriculture” and “sustainable agrifood systems”. The “sustainable agriculture” models—comprising organic farming, regenerative agriculture, climate-smart agriculture, carbon-capture agriculture, and nature-based solutions—focus primarily on improving ecological sustainability through farm-level practices. These models emphasize reducing external, industrial inputs, enhancing biodiversity, and promoting climate resilience, relying on technological and market-based solutions to address environmental concerns. On the other hand, the “sustainable agrifood systems” models—agroecology, alternative food networks, and permaculture—offer more ambitious visions of systemic transformation. These approaches not only seek to implement environmentally sound practices but also aim to reconfigure the broader food system by challenging corporate power, promoting local governance, fostering food sovereignty, and prioritizing social justice. Grounded in grassroots movements, these models emphasize social justice and economic viability in addition to ecological sustainability. This paper’s contribution lies in its comparative analysis of the wide array of sustainable alternatives, highlighting both their strengths and limitations. Adopting an agrarian political economy perspective, it critiques the former camp for limited engagement with structural issues inherent in capitalist agriculture and the latter camp for underplaying the importance of industrial agriculture for national development in the Global South.

Grazing for dollars: responsible investing for healthy and sustainable animal agriculture in Australia

AbstractInvestments by the global finance sector contribute to industrial-scale agriculture along with its harmful environmental impacts, making their actions significant in supporting or opposing sustainable food systems transformation. Previous research has shown that institutional investors identify animal agriculture as an important consideration with respect to environmental, social and governance (ESG) issues regarding sustainable food systems. This study aimed to explore ways in which so-called ‘responsible’ investors in Australia consider risks related to animal agriculture, and whether existing ESG metrics are ‘fit-for-purpose’ for assessing issues related to sustainable animal agriculture. Nineteen semi-structured interviews were conducted with responsible investors and relevant non-government organisations (NGOs) in Australia. We found that the responsible investment sector lacked mechanisms to recognise the inter-connections between animal agriculture and multiple environmental and social outcomes. Furthermore, we found that investors largely focused on ‘techno’ solutions to the impacts of animal agriculture, such as alternative proteins, through a ‘single issue’ lens. They rarely made connections to other relevant ‘food systems’ issues, such as health. We conclude that holistic approaches are needed to monitor and assess the impacts of animal agriculture in the investment sector and suggest that integrated ‘food systems’ metrics will be necessary to inform these approaches.

Milk contamination in Europe under anticipated climate change scenarios

Transforming the food system while addressing climate change requires proactive measures based on quantitative projections of anticipated future conditions. A key component of the food system that must be considered during this transformation is food safety, which is the focus of this paper. Milk safety has been selected as a case study. Future milk contamination levels in Europe, in terms of total bacterial counts, are evaluated under various climate change scenarios. Projections from multiple climate models are integrated into a data-driven milk contamination model, validated using data from Malta, Spain, and Belgium. The modeling framework accounts for variability among dairy farms and the inherent uncertainties in climate projections. Results are presented through geographical heatmaps, highlighting coastal and southern areas such as Portugal, Western Spain, Southern Italy, and Western France as regions expected to face the highest bacterial counts. The analysis underlines the significant roles of humidity and wind speed, alongside temperature. It also examines compliance with the regulatory threshold for raw milk, revealing an increased frequency of summer weeks exceeding the threshold of 100,000 colony-forming units. Based on this analysis, regions are classified into low-risk, high-risk, and emerging-risk categories. This classification can guide the selection of farm strategies aimed at meeting future food safety standards. By informing these decisions with the anticipated impacts of climate change, the food system can be future-proofed.

Exploring the Extraction and Application of Anthocyanins in Food Systems

The continued use of synthetic additives in food production and preservation has raised concerns among consumers, given their potential negative health effects. Researchers and food industry experts have been exploring plants with potent functional compounds as an alternative source of natural compounds such as anthocyanins, which can be utilized to produce safe food additives. Given their various biological activities, great potential exists for anthocyanins to be used as additives to preserve food or produce functional foods with health benefits. However, to fully realize the economic and health benefits of anthocyanins, a deep understanding of the different plant sources of anthocyanins, as well as their composition, extraction techniques, and function in various products, is warranted. Therefore, this paper critically reviews the different plant sources of anthocyanins and their application in the food and nutraceutical industries, highlighting emerging extraction techniques, health benefits, and challenges in the use of anthocyanins in the food industry. This review also offers insights that could be used in future research and help establish novel and sustainable methods for manufacturing anthocyanin-based value-added products and ingredients.

Food for Thought: Nourishing Cardiovascular Health Amidst the Exposome.

The cumulative exposures of an individual during their lifetime, known as the exposome, encompass environmental exposures and lifestyle factors that significantly impact cardiovascular health. The exposome concept aims to provide a comprehensive framework for understanding how various exposures combine to influence disease risk and health outcomes over a lifetime. Diet is a well-studied aspect of the exposome, recognized as a critical contributor to cardiovascular health and influencing various other health metrics and behaviors. Furthermore, understanding agricultural food systems and their interrelationships with dietary choice and impacts on environmental and human health requires a systems approach. Through a review of the literature, this publication will (1) elucidate the interconnections between the exposome and cardiovascular diseases through the lens of agricultural systems and environmental health; (2) examine the effect of diet on cardiovascular health; (3) examine the influence of socioeconomic and cultural factors on the agricultural food system and dietary choices; and (4) highlight the importance of adopting a systems approach that integrates dietary interventions with sustainable agricultural practices, emphasizing the need for holistic strategies to address the root causes of cardiovascular health issues through balanced human and environmental health interventions.

Advanced Biofuel Value Chains Sourced by New Cropping Systems With Low iLUC Risk

ABSTRACTIncreasing lignocellulosic feedstock for advanced biofuels can tackle the decarbonization of the transport sector. Dedicated biomass produced alongside food systems with low indirect land use change (iLUC) impact can broaden the feedstock availability, thus streamlining the supply chains. The objective of this study was the design and evaluation of advanced ethanol value chains for the Emilia‐Romagna region based on low iLUC feedstock. Two dedicated lignocellulosic crops (biomass sorghum and sunn hemp) were evaluated in double cropping systems alongside food crop residues (corn stover and wheat straw) as sources to simulate the value chains. A parcel‐level regional analysis was carried out, then the LocaGIStics2.0 model was used for the spatial design and review of the biomass delivery chain options regarding cost and greenhouse gas (GHG) emissions of the different feedstock mixes. Literature data on bioethanol production from similar feedstocks were used to estimate yields, process costs, and GHG emissions of a biorefinery process based on these biomasses. Within the chain options, GHG emissions were overly sensitive to cultivation input, mostly N‐fertilization. This considered, GHG emissions resulted similar across different feedstock with straw/stover (averaging 13 g CO2eq MJ−1 fuel), sunn hemp (14 g CO2eq MJ−1 fuel), and biomass sorghum (16 g CO2eq MJ−1 fuel). On the other hand, the bioethanol produced from biomass sorghum (608 € Mg−1 of bioethanol) was cheaper compared with straw (632 € Mg−1), sunn hemp (672 € Mg−1), and stover (710 € Mg−1). The bioethanol cost ranged from 0.0017 to 0.020 € MJ−1 fuel depending on the feedstock, with operations and maintenance impacting up to 90% of the final cost. In summary, a single bioethanol plant with an annual capacity of 250,000 Mg of biomass could replace from 5% to 7% of the Emilia‐Romagna's ethanol fuel consumption, depending on the applied sourcing scenario.

Design Thinking Approach to Create Impact Assessment Tool: Cities2030 Case Study

This paper presents the development and testing of an impact assessment tool for the Cities2030 project aimed at transforming city-region food systems to align with the European Union’s Food2030 policy and the European Green Deal. This study highlights the importance of sustainable urban food systems, focusing on food security, environmental sustainability, and public health. Using a design thinking approach, this research emphasizes co-creation, stakeholder engagement, and iterative refinement, developing a flexible, multi-dimensional framework adaptable to diverse city-region contexts. Through collaboration with 65 stakeholders, this tool was tailored to meet the socio-economic and environmental needs of different regions. Case studies from Cities2030 partner cities demonstrate its effectiveness in fostering cross-sectoral collaboration, enhancing community participation, and driving food system innovations. Key findings reveal measurable impacts across social, environmental, and economic dimensions, while addressing challenges like regional disparities in data collection and the need for improved long-term tracking of sustainability metrics. This study concludes by underscoring the role of adaptive, inclusive strategies in assessing urban food systems’ sustainability and resilience and suggests that the tool’s framework could be applied to other urban sustainability areas, such as energy and water management.

Unveiling Genetic Diversity in Grain Amaranth through K-Means Clustering and Principal Component Analysis

Grain amaranth (Amaranthus spp.) is a highly versatile and nutrient-dense pseudo-cereal that has gained increasing importance in global food systems. Developing diverse varieties and hybrids of grain amaranth (Amaranthus spp.) is essential for harnessing its full potential as a climate-resilient and nutritionally rich crop. Germplasm studies provide a comprehensive understanding of the genetic diversity within amaranth, facilitating the breeding of improved cultivars that combine desirable traits such as higher yield, enhanced nutritional content, and increased tolerance to biotic and abiotic stresses. Varietal development and hybridization can optimize characteristics like seed size, growth habit, and adaptability, making amaranth more suitable for a range of agroecological zones. In this direction present study conducted by evaluating 180 grain amaranth germplasm accessions for yield and contributing factors during the summer 2024 at the ICAR-IISS Regional Station in Bengaluru adjacent to NSP. Genetic distances among 180-grain amaranth germplasm accessions were determined using K-means clustering, resulting in 06 distinct groupings. Cluster V comprised of more number of accessions (48) and the least number of accessions in cluster VI (15). As per PCA, eight eigen values explains the total variance; among which PC1 explained maximum variance 82.06% followed by PC2, PC3, PC4, PC5, PC6, PC7 and PC8 explained 8.87%, 5.39%, 1.63%, 1.02%, 0.51%, 0.45% and 0.07 % respectively.

Estimating the effect of biological nitrification inhibition-enabled sorghum on nitrogen fertilizer consumption, life cycle GHG emissions, farmer's benefit and fertilizer subsidy from Indian sorghum production

Biological nitrification inhibition (BNI) effectively curtails nitrogen (N) loss and enhances N utilization efficiency. BNI is increasingly important as a technology for mitigating greenhouse gas emissions and water pollution in countries with high N fertilizer consumption. This study aimed to evaluate the potential impacts of BNI-enabled sorghum varieties with a 30 % soil nitrification inhibition rate for a major sorghum-growing state (Maharashtra, India). We analysed the farm survey data collected for Rabi sorghum in 2020–2021 (n = 250) and for Kharif sorghum in 2022 (n = 209). Life cycle greenhouse gas (LC-GHG) emissions were estimated using a life cycle assessment with a cradle-to-farm gate perspective. The results showed that adoption of BNI-enabled sorghum reduced N fertilizer application in the Rabi and Kharif seasons by 8.0 % and 7.4 % and area-scaled/yield-scaled LC-GHG emissions by 15.6 % and 11.2 %, respectively, while increasing farmers' benefits slightly. These changes could reduce the government's expenditure on urea fertilizer subsidies by 9.1 %. However, many farmers indicated that they would not change N fertilizer application even if the yield per N fertilizer application increased. Even under these circumstances, area-scaled/yield-scaled LC-GHG emissions will be decreased by 11.3 % and 13.5 % in the Rabi season and 8.1 % and 10.2 % in the Kharif season, respectively. The yield and farmers' benefit will increase by 2.5 % and 4.9 % in the Rabi season and by 2.4 % and 6.5 % in the Kharif season, respectively, but the government's expenditure on fertilizer will not decrease. These results indicate that BNI-enabled sorghum can be introduced into countries where fertilizer use is low. This study shows the potential impacts of BNI-enabled sorghum under two scenarios; N fertilizer consumption is reduced or maintained. Discussions on the N fertilizer consumption under BNI-enabled sorghum are needed to establish a sustainable food system, especially in countries with high N fertilizer consumption.

Empowering local food security: A systematic review of community grain banks

Community food systems, exemplified by initia­tives like community grain banks (CGBs), play a crucial role in achieving Sustainable Development Goal 2 (SDG 2), which aims to achieve zero hunger and ensure food security by 2030. This paper draws upon a systematic review of the literature on CGBs to emphasize the relevance of community institutions in enhancing local food security. Adhering to Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, this paper reviews 16 aca­demic articles, two theses, and 19 online sources. The study reveals that CGBs offer immediate relief during food shortages, empower women, stabilize farmers’ income, reduce debt burdens, foster social trust, and enhance community resilience. This review highlights the need for international stake­holders to prioritize supporting CGBs to preserve the self-sustaining systems. Tailoring CGB designs to community-specific needs could significantly enhance local food security, offering actionable strategies to mitigate severe food insecurity globally and regionally.

The Role of Wild Food in Fostering Healthy, Sustainable, and Equitable Food Systems

In this paper, we provide an overview of the research and literature on wild foods (i.e., edible plants that grow without human cultivation and/or animals harvested from their natural habit, i.e., food sourced from “hunting and gathering”) and their ability to assist food systems in becoming more sustainable and equitable. We begin with a discussion on the green revolution and the global capitalist food system that has been created and is dominated by large agribusinesses. Next, we turn to a brief discussion of how homogenizing the food system, as large agribusinesses have, leads to a corresponding loss of local culture. We then provide an overview of the main areas of wild food research, including nutrition, reducing food insecurity, the importance of cultural and shared knowledge, and sustainability. Our discussion stresses how focusing too heavily on the dichotomy of cultivated vs. wild food is problematic. Rather, lessons regarding health, sustainability, and equity can be learned from foragers, hunters and gathers.

Indulging in Tempting Yet Unhealthy Delights: Exploring the Moderating Influence of Gender and Motivation for Healthy and Sustainable Eating

Individuals frequently encounter alluring food temptations that can disrupt their efforts to follow a healthy diet. These temptations may trigger pleasurable thoughts and sensations, potentially leading to unhealthy eating habits and obesity, which misalign with the goals of sustainable food systems to promote overall well-being. However, there is limited knowledge regarding how individual differences such as gender and motivation for healthy eating might impact individuals’ responses to unhealthy food temptations. In an experimental investigation, 245 participants were exposed to a tasty but low-nutrient food product (potato crisps). The results provide several new insights: (a) when individuals’ motivation for healthy eating is low, pleasurable experiences have a positive impact on perceived dietary quality; (b) pleasurable feelings also directly reduce willingness to consume potato crisps; (c) gender influences the relationship between pleasure-feeling and willingness to eat, with a negative relationship for women and a non-significant relationship for men; and (d) among women, there is a positive relationship between arousal and willingness to eat, while this relationship is non-significant for men. This study adds to the body of knowledge already available on food temptations, nutrition, and sustainable eating.

Analyzing Consumer Motivations and Behaviors Towards Upcycled Food from an Environmental Sustainability Perspective

Green energy consumption is a pressing global environmental issue that necessitates the optimization of food system circularity to effectively utilize natural resources. The rise of food technology has introduced upcycled food as a promising solution for reducing food waste and promoting sustainability. Despite its potential, research on consumer attitudes toward upcycled food remains scarce. This study investigates the role of upcycled food in shaping Taiwanese consumers’ behaviors in response to environmental challenges, utilizing the value–attitude–behavior (VAB) model with a focus on variables such as “product novelty”, “green perceived value”, and “ethical consumption”. Using convenience sampling, 297 valid responses were collected, achieving a response rate of 91.1%. Findings indicate that health values significantly enhance positive attitudes toward upcycled food, which in turn positively influences behavioral intentions. However, neither green perceived value nor product novelty significantly affected these intentions. These insights highlight the importance of prioritizing health values, consumer attitudes, and ethical consumption in marketing strategies for upcycled food to engage potential consumers and promote environmental sustainability. This study addresses a critical gap in the existing literature and suggests a strategic direction for the food industry.

Elements of environmental and socioeconomic sustainability related to the food system: A meta-synthesis

This study aims to understand how the individual elements of the food system relate to sustainability through a meta-synthesis. Changes in food production and consumption in recent decades have had a detrimental effect on human health and the environment. This study helps to explain the existing gap that affects the entire process from food production to the final consumer by discussing the elements that comprise the food system dimensions of a healthy and sustainable diet. The meta-synthesis approach makes it possible to capture elements and their relationship to each other and to generate explanations about theoretical relationships. With this in mind, searches were conducted in the Scopus database, initially selecting 1,362 studies that contained previously selected search descriptors. Subsequently, an exploratory analysis of the titles and abstracts of the articles was conducted, resulting in a set of twenty case studies centered on the topic of interest. After applying inclusion and exclusion criteria, twelve studies remained to make up this meta-synthesis. The elements that emerged from the analytical synthesis of the articles favor or hinder the transition to healthy and sustainable food systems and have an impact on four dimensions: Production, supply, marketing and consumption, as well as on the food system as a whole. As a theoretical contribution, this study explains the elements and stressors of sustainable food systems. As a practical contribution, based on these stressors, action plans can be developed involving different stakeholders and public policies to develop public policies that promote healthy and sustainable diets.

Protecting nutrition in a food crisis.

Food insecurity and malnutrition are rising worldwide due to disruptions in food systems related to interconnected health-, climate- and conflict-related crises. Although governments globally are committed to addressing nutritional challenges, policy responses have increasingly focused on food security and, particularly, on food affordability. However, these short-term measures often overlook the necessity of integrating nutritious foods into the food system to ensure improved long-term nutrition. By drawing on the United Nations Committee on World Food Security's Voluntary guidelines on food systems and nutrition, this article outlines opportunities for policy-makers to integrate nutrition into key elements of the crisis response. Key policy areas where nutrition could be further integrated include social protection, agricultural investment, trade policy and urban planning. Strengthening the focus of nutrition in these measures will be essential to establish long-term incentives that support food systems transformation for improved nutrition. Drawing on theories of the policy process, I propose that stronger governance and cross-sectoral dialogue will be critical to achieve sustained nutritional outcomes. Health policy-makers can play a leadership role in supporting cross-sectoral policy change by carefully framing the policy issues, advocating for institutional structures that promote collaboration across sectors to prioritize nutrition, and strengthening the management of conflicts of interest in food system policy-making.

Principles, barriers and enablers to agroecological animal production systems: a qualitative approach based on five case studies

Agroecology is among the most promising options to alleviate the negative impacts of animal farming on the environment and build local food systems based on ethically-acceptable production methods. So far, most of the research on agroecological animal production systems was conducted at farm scale, and the potential of agroecological principles addressing social dimensions and food system level approaches has been underexplored. Here, we analyze how the whole set of agroecological principles was mobilized in five case studies on grassland-based, silvopastoral or integrated crop-livestock systems in Switzerland, Guadeloupe, French uplands, Bulgaria and Andalucía. Following a multilevel perspective, we propose a new eight-category framework to categorize barriers and enablers in these different socioecological contexts, and discuss the implications of these results for scaling out and scaling up agroecological niche innovations in animal production areas. Though we could observe activities related to each agroecological principle in each case study, the relative importance of each principle differed. For instance, in Switzerland the focus was on ecological processes operating in multi-species mixtures, and therefore on mobilizing principles of input reduction, synergy, soil health and biodiversity, while in Andalucía, a civil society organization, a regional agricultural office, researchers, and farmers mainly mobilized transformational principles at the food system level, e.g. social values, connectivity and participation. Such contrasts highlight how agroecology allows different equilibria among principles, adapting to the needs of farmers and local communities. Inadequate infrastructure and lack of technology were frequently reported as barriers to agroecological transitions. Policy needs to go beyond the mere support of agroecological practices on livestock farms and adopt a systems approach looking downstream and upstream if it is to enable a large-scale agroecological transition with EU public policies. Market as an enabler was linked to direct sales and short distribution circuits, generating added value to the benefit of local communities. Most agroecological systems benefited from a positive image among citizens and consumers, but cultural barriers resulted from change in product characteristics, e.g. veal meat color in dairy system that promote long-lasting cow-calf contact. All case studies were very advanced in the social dimensions of agroecology, and cooperation networks were always reported among the enablers for scaling out. The multi-actor network approach fostered knowledge exchange between farmers, researchers and citizens, and allowed participants to share values. Long-term commitment from local practitioners is required so that co-designed solutions are implemented, which can strengthen the economic and social viability of animal production areas.
