This chapter explains the reasons for the stalemate in the WTO negotiations on domestic agriculture support, public stockholding (PSH) for food security purposes, and fisheries subsidies. The negotiations are crucial for achieving Sustainable Development Goals related to zero hunger, food security, sustainable agriculture, and marine resources. In agriculture, members are divided on disciplining trade-distorting support and addressing historical asymmetries. The PSH negotiations are contentious owing to disagreements on a permanent solution and calculation of the external reference price. Fisheries subsidy negotiations have stalled on the issue of over-capacity and overfishing subsidies, despite progress on illegal, unreported, and unregulated fishing.
Dryland agriculture faces escalating constraints from water deficit, heat stress and soil salinity, necessitating the harnessing of adaptive diversity beyond modern wheat cultivars. Wild wheat relatives (WWRs) within the Triticeae harbour key dryland-adaptive traits, including deep, plastic root systems, osmotic adjustment, Na+/K+ homeostasis and heat-responsive photosynthesis, all of which are critical for maintaining yield stability under water-limited conditions. This review synthesizes recent advances in pangenomics, genome-wide association studies, speed introgression (genome-scale introgression under speed breeding) and genome editing, which enable more precise mining and deployment of WWR alleles while reducing linkage drag and improving selection efficiency. Importantly, we integrate biological constraints with conservation and policy considerations, highlighting how fragmented ex situ representation, limited phenotyping capacity in dryland regions, and complex access-and-benefit-sharing frameworks under the Convention on Biological Diversity, the Nagoya Protocol, and the International Treaty on Plant Genetic Resources for Food and Agriculture constrain the practical utilization of WWR diversity. By identifying underexplored WWR and allied taxa (e.g., Aegilops searsii and Elymus spp.), priority trait categories, and target dryland agroecosystems, this review provides a unified conservation-to-breeding framework that advances beyond previous syntheses and repositions WWR from genetic reservoirs to deployable resources for climate-resilient wheat improvement.
To optimize school food baskets in Ghana to meet newly proposed food and nutrition targets while considering cultural acceptability and cost.
Design:
Modeling study. Data on existing school meal menus was collected from various regions to provide baseline inputs. Linear programming (LP) was used to model school meal baskets that satisfied minimum nutrient and food targets for school meals while meeting cost and acceptability constraints. Five LP models were tested, each varying in budget constraints and acceptability/food-based parameters.
Setting:
Ghana
Participants:
NA
Results:
Baseline school food baskets were significantly deficient in energy, protein, iron, zinc, vitamin A, folate, vitamin B12 and vitamin C compared to food and nutrient standards for school meals in Ghana. Optimization resulted in school food baskets that met cost, nutrient and food-based/acceptability targets but with substantial deviations from baseline. Achieving nutritional adequacy within cost limits increased reliance on animal-source foods and led to higher environmental impacts, indicating trade-offs between nutrition, affordability, and environmental sustainability.
Conclusion:
The study underscores LP’s potential for enhancing school meals in Ghana but highlights the need for increased financial investment for reaching dietary goals. Addressing local realities and cultural preferences is essential for implementing effective, sustainable school meal strategies and improving child health.
Archaeology is not a solitary discipline concerned only with digging up the past; rather, its wide potential for transdisciplinary collaboration and unique deep-time perspective provide traction for real-world current and future impact. Here, the author proposes integration of systems thinking, small-wins psychology and a more creative interdisciplinary approach as ways for archaeologists to address the existential ‘polycrisis’. Using food security as an example, this article argues that, as archaeologists, we should focus far more attention on the polycrisis than we do at present, that we can make a difference in addressing it and that we have a responsibility to try.
This paper contributes to the discussion on the link between international trade policy and food and nutrition security by looking at whether and how these concepts are addressed in Preferential Trade Agreements (PTAs). We compile a dataset covering almost 600 PTAs that entered into force between 1948 and 2024, and apply textual analysis to show that the number of references to food security has increased over recent decades. To analyse the role of the WTO Agreement on Agriculture (AoA) in shaping the rules and practices of international food trade, we investigate the placement, function, and significance of food security provisions in four case studies, looking at the extent to which the regulatory approaches of these PTAs align with or diverge from the relevant provisions of the WTO AoA. Our study reveals that, despite the growing prominence of food security and nutrition in PTAs, their regulatory approaches largely align with the AoA and seldom overcome its shortcomings. While some agreements introduce broader and more contemporary understandings of food security, binding commitments remain limited and structural tensions between national and global objectives persist.
Science diplomacy (SD) is increasingly used to encourage international collaboration and produce knowledge for global challenges. This study explores how a 12-year SD campaign helped shape a scientific community around the Water–Energy–Food (WEF) Nexus – a framework linking resource systems for sustainability. By analyzing events, recruitment efforts, and over 1,600 scientific publications, we trace how this community formed, evolved, and interacted with policy agendas. The results show both progress and challenges: growing collaboration and new research directions, but also delays between diplomatic goals and scientific output. The findings offer insights into how SD can support long-term sustainability through knowledge and institutional networks.
Technical summary
Global sustainability challenges have increased reliance on SD to mobilize research communities and align scientific production with policy goals. A central mechanism in these efforts is the formation of scientific epistemic communities (ECs), yet evidence on how SD contributes to durable communities and actionable knowledge remains limited. This study examines a 12-year SD campaign promoting the WEF Nexus, a framework encouraging integrated governance of interdependent resource systems. We combine qualitative coding of 143 SD events and 107 scientific recruitment activities with bibliometric analysis of 1,643 WEF publications (2011–2022). This mixed-methods approach traces the temporal and structural evolution of the WEF EC, focusing on recruitment patterns, thematic consolidation, and co-authorship network resilience. Findings show that SD efforts broadened participation, supported the emergence of a recurring group of authors, diversified journal outlets, and expanded global collaboration networks. Network simulations reveal that by 2022 the EC was moderately resilient but remained dependent on a small subset of strategically connected researchers. The analysis also identifies a temporal lag between SD agenda-setting and scientific response, raising considerations about the alignment of science and policy cycles. Overall, the results clarify conditions under which SD can catalyze scientific community formation and support sustainability-oriented knowledge infrastructures.

How does SD shape global research? Our new study on the WEF Nexus reveals key mechanisms and insights.
Food security is a common term within the region, but its meaning is unclear. This chapter argues that the term is a means to demarcate the Gulf’s access to food from the rest of the region; it submits it as a form of biopolitics that rationalises circulation, access and consumption. It shows how food imports are central to economic growth and development and how this is managed by governments. It also argues that food security is a basis for political legitimacy and the identification of problem and solution is a performative act.
Food banks in the United States are part of the robust food system that addresses hunger among the population. A comprehensive description of the challenges faced by food banks in the United States is crucial to understanding and responding to the diverse needs. A careful assessment of the literature highlights opportunities not only to improve the efficiency of services, but also to identify strategies and strengthen partnerships to build a sustainable food system.
Technical Summary
This systematic scoping review aimed to characterize the challenges in the US food banks and recognize opportunities for a sustainable food system. Five electronic search engines/databases, including PubMed, ScienceDirect, Web of Science, Embase, and Cochrane Library, were searched for literature published between 2013 and 2025. The search results were reported per the PRISMA guidelines. Of the 123 selected articles, a majority covered operational challenges (n = 26), strategies to improve operations (n = 16), challenges related to nutrition and health (n = 25), followed by beneficiaries (n = 20), emergencies (n = 15), resources (n = 14), and chronic diseases (n = 7). Supply chain, partnerships, distribution, and adherence to equity principles were included under operational challenges. Fiscal, human resource, and infrastructural challenges were discussed under resource challenges. Beneficiaries, particularly the elderly, people with disabilities, refugees, and their unmet needs, were documented. During the pandemic, a lack of trained staff and a disrupted supply chain tested the resilience of food banks. The need to consider the participants’ nutritional needs was recognized across a few domains. Opportunities for sustainable food systems emerged through exploring local resources, partnerships, and community engagements. Innovations in technology and efficient inventory management systems to minimize food waste, and education initiatives to foster self-management emerged as opportunities. Policies that advocate food and nutrition security will create a resilient food system.

Agriculture is the single largest cause for transgressing planetary boundaries. A global transformation to sustainable intensification is required in order to hold the windows open for meeting the Paris climate accord of limiting global warming to 1.5°C and the global biodiversity framework of halting loss of biodiversity, while securing food for a growing world population. Conservation Agriculture (CA) offers the only universally applicable agricultural practices that can be adopted at scale and speed, i.e., across all agro-ecological zones within the coming 1–2 decades. We review the rationale, evolution, and prospects of CA across the world.
Technical summary
We estimate that CA has almost doubled from approximately 100 to 200 M ha between 2008/09 and 2018/19, covering approximately 15% of global cropland. Our projections until 2024, estimates another 30% increase (to 250–270 M ha), with a potential of expanding to 50% of global cropland area by 2050 (≈700 M ha).
CA includes three fundamental principles; zero-tillage, cover crops, and diverse crop rotations. Converting from conventional tillage-based ploughing to CA sequesters ∼0.1–2 t C ha−1 yr−1. Considering an average sequestration potential with CA of 0.5–0.9 t carbon ha−1 y−1, converting the total 1.5 billion ha of global cropland to CA could sequester 0.41–0.82 billion t of carbon ha−1 y−1. Additionally, CA reduces pressure on biodiversity, increases soil moisture holding capacity, builds resilience of plant production to extremes, and reduces fuel use for tillage by 50–70 %.
CA has proven to maintain, stabilize, and increase high yield levels in intensive agricultural systems, which currently are stagnating or even decreasing in tillage-based agricultural systems, while significantly increasing yield levels on relatively poor or degraded agricultural soils. While CA is not a panacea for all food production challenges, it is difficult to find a more ready-to-scale farm practice.

This chapter presents agreements between Indigenous peoples and governments, specifically those in Bangladesh and Mexico that focus on their roles in promoting sustainable development. The introduction sets the stage for subsequent discussions by emphasizing the importance of global legal and policy frameworks in shaping these agreements, with the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) and the global Sustainable Development Goals (SDGs). The two case studies from Bangladesh and Mexico are then analysed, shedding light on the unique characteristics, provisions, and outcomes of agreements between Indigenous peoples and governments in these contexts. A comparative analysis is conducted to identify commonalities, differences, and lessons learned from these case studies. Ultimately, the chapter concludes by highlighting the significance of ongoing dialogue, collaboration, and respect for Indigenous rights in achieving sustainable development goals globally. It underscores the importance of incorporating Indigenous perspectives and aspirations into the design and implementation of such agreements.
The aim of this review is to examine why cultural food security and cultural food sovereignty should be prioritised and embedded within conventional food security frameworks. It demonstrates how culturally grounded, community-driven approaches foster more just, sustainable and empowering food systems for ethnically diverse, Indigenous and local communities, while highlighting the limitations of conventional metrics that overlook socio-cultural, political and ecological dimensions essential to resilience. Conventional food security focuses on access to sufficient, safe and nutritious food, often sidelining access to culturally appropriate and spiritually meaningful foods that are integral to cultural identity and tradition (cultural food security) and the authority and decision-making power held by local people over their foodways (cultural food sovereignty). Its market-based, individualistic measurement paradigms further neglect collectivist, traditional and spiritual food values, resulting in assessments that may conform to global standards yet produce flawed outcomes, misaligned interventions and continued marginalisation of ethnically diverse, Indigenous and local communities. Drawing on socio-cultural, political, economic and environmental frameworks, the review demonstrates how food sovereignty and cultural food security provide more sustainable, equitable and empowering pathways for communities. It underscores the need for community-driven, culturally grounded food policies.
To estimate the prevalence of nutrition security and examine its association with community food environment factors, including food access and affordability.
Design:
This cross-sectional study used data from the 2012–2013 National Household Food Acquisition and Purchase Survey, including its restricted-use Geography Component (FoodAPS-GC). Household nutrition security measure was derived by combining self-assessed food security and self-rated diet quality indicators into four categories: food secure with high diet quality (FSHD), food secure with low diet quality (FSLD), food insecure with high diet quality (FIHD) and food insecure with low diet quality (FILD). Only FSHD households were considered nutrition secure. Multinomial logit analysis identified factors associated with nutrition security.
Participants:
4685 households with primary respondents aged 20 years or older
Setting:
Nationally representative sample of US households
Results:
Approximately 31·0 % of households were classified as nutrition insecure, including 15·0 % as FSLD, 9·3 % as FIHD and 6·7 % as FILD. The remaining 69·0 % were nutrition secure (FSHD). Nutrition insecurity was significantly associated with younger age, lower educational attainment, lower income, obesity, smoking and poorer self-rated health. Food environment factors, including low geographic access to food and higher local food prices, were not significantly associated with nutrition security. Relying on someone else’s car to reach a primary food store was linked to higher odds of nutrition insecurity.
Conclusions:
The proposed nutrition security measure can be used to monitor nutrition security in national surveys. Comprehensive measures of the food environment are needed to understand its relationship with nutrition security and to guide targeted policy interventions.
Household food insecurity has previously been associated with psychological distress, and subsequently, poorer diet quality. Further understanding of this relationship is required to improve nutritional outcomes, with food-related concerns suggested as one potential mechanism. Therefore, the current pre-registered (https://osf.io/zd3ak) study conducted cross-sectional secondary analyses of Wave 6 (October 2022–January 2023) of the Food and You 2 survey administered in adults aged 16 years and over across England, Wales, and Northern Ireland (N = 2315), to explore the differential prevalence of food-related concerns in people experiencing food insecurity. Exploratory analyses also identified characteristics of food support users (food bank or social supermarket; N = 467) and quantified associations between food support use and the same food-related concerns. People experiencing marginal (OR = 1.43, p = 0.02) and low food security (OR = 1.51, p = 0.02) (relative to high food security) were significantly more concerned about food prices, but this association was not seen in people experiencing very low food security. Both food bank and social supermarket use were predicted by very low food security (food bank OR = 6.05, p < 0.001; social supermarket OR = 2.40, p = 0.02) and having a long-term health condition (food bank OR = 3.91, p = 0.00; social supermarket OR = 3.17, p = 0.00). Food bank users were less concerned about healthy eating (OR = 0.33, p = 0.00) whereas social supermarket users were less concerned about food prices (relative to non-users) (OR = 0.40, p = 0.01). Food-related concerns, particularly regarding food prices, are differentially associated with food security status and food support use. Findings could support specific interventions to promote better diet quality and improve health and wellbeing in populations experiencing food insecurity.
Integrated Soil Fertility Management (ISFM) refers to a holistic approach to managing soil fertility that combines a variety of techniques and practices to improve soil health and enhance agricultural productivity, particularly in smallholder farming systems. Despite the associated higher labor and other input demands associated with ISFM adoption, there is limited empirical evidence regarding the positive outcomes of these investments at the household level. Using data from 380 tomato farmers in three regions of Ghana, we explore the relationship between ISFM adoption and household welfare. The methodology employed relies on inverse probability weighting regression adjustment (IPWRA). The findings reveal that ISFM adoption positively impacts household welfare by increasing net income by GH₵436.88 ($60.43)/ha, improving household assets by GH₵518.17 ($71.67)/ha, enhancing food security by 1.23 points, and reducing household expenditure by GH₵57.39 ($7.94)/ha. The results highlight ISFM’s potential to enhance smallholder welfare through increased income, improved household assets, and better food security, contributing to poverty reduction and sustainable agricultural development. Policies should focus on improving access to fertilizers, seeds, and pesticides, coupled with extension services and farmer education programs to promote ISFM adoption. Tailored interventions targeting older and more experienced farmers, as well as household heads, are essential to overcome barriers to adoption and maximize the economic and welfare benefits of ISFM practices.
The rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping system (RWCS), recognized as the world’s prime agricultural system, plays a pivotal role in global food security by providing employment for millions and ensuring a steady income, thereby serving as a cornerstone for farmers’ livelihoods and attracting numerous investors. However, the sustainability and efficiency of this critical system face momentous threats due to climate change, which affects both the quantity and quality of wheat and rice crops. Currently, the growth frequency of the RWCS has declined, principally due to evolving challenges such as weed infestation, delayed wheat sowing after rice harvest, soil salinity, and the prevalence of various diseases. Among these challenges, weeds pose a considerable threat to the cultivation of both rice and wheat. Seed germination, a crucial stage in the plant life cycle, is influenced by various factors, including dormancy, temperature, moisture, oxygen, and light. A comprehensive understanding of weed ecology is essential for identifying vulnerabilities that can be targeted for improved weed management. Population-based threshold models, including hydro-time and thermal time, provide insights into germination patterns, contributing to the overall fitness of weed species. The ability to predict species’ responses to climate change is paramount, and these models are effective in comprehending and controlling weed emergence behavior across diverse environments. Hence, this review paper emphasizes the reevaluation of current weed management practices, focusing on investigating ecologically sustainable approaches for efficient weed control.
This study tested the effects of soil amendment with orange peel powder (Citrus sinensis L.) on Brassica rapa growth, the performance of the aphid Myzus persicae Sulzer, and the foraging behaviour of its parasitoid Aphidius gifuensis Ashmead. Three peel: soil ratios (1:10, 1:15, 1:20 w/w) were compared with an unamended control. The 1:10 amendment significantly reduced seed germination, plant height, leaf size, and fresh weight, while the 1:20 amendment also decreased fresh weight. Aphid nymphal development was significantly delayed in the 1:10 and 1:15 treatments, and adult weight gain was reduced in the 1:15 treatment. Aphid population growth and parasitoid foraging time were unaffected across treatments. The results indicate that orange peel amendments can delay aphid development but also suppress plant growth at higher concentrations, highlighting the need for optimized application rates. This study supports further exploration of orange peel as a sustainable soil amendment in integrated pest management.
Food banks are a particular type of voluntary sector organization that bridges the government sector, private sector, and civil society. This special issue of Voluntas adds to the stream of research on the role of food banks in addressing food insecurity in high-income countries. We begin by outlining the concept of food insecurity and a number of direct responses to alleviating food insecurity at the household and individual level by governments and the voluntary sector. We then look at the potential and limitations of food banks in addressing food insecurity in high-income countries, distinguishing between anti-hunger research and research framed as addressing community food security. Based on the set of seven papers included in this special issue, we call for further research that bridges both these approaches.
In the last century, economic sanctions have been used with increasing frequency as a tool of global governance, as well as in foreign policy. At the same time, they have long been criticized for their lack of success in achieving the stated goals of the sanctioners. However, what has received far less attention is the question of whether, and when, it is legitimate to impose sanctions. It has become increasingly clear that the humanitarian impact of sanctions may be devastating, affecting healthcare and food security, as well as harming vulnerable populations such as migrants. Sanctions may interfere with the work of humanitarian aid organizations, create diplomatic problems, and undermine the autonomy of sovereign states. Further, there can be significant legal questions regarding the use of sanctions, whether they are imposed by states or by institutions of global governance.
United States sanctions undermine Iran’s ability to import critical agricultural products, especially wheat. Despite long-standing exemptions for humanitarian trade, sanctions have fragmented Iran’s wheat-supply chain, deterring major commodities traders, interrupting payment channels, and delaying shipments. While Iran does continue to import wheat to meet its food security needs, commodities traders can extract a higher price from Iranian importers, citing the unique challenges of exporting to the country. In this way, sanctions contribute to structurally higher prices for wheat in Iran. The country’s growing dependence on wheat imports, driven by demographic changes and worsening climate conditions, has made these disruptions more acute. Efforts to mitigate these effects, such as humanitarian trade arrangements launched by multiple US administrations, have largely failed due to bureaucratic inefficiencies and financial sector overcompliance. As a result, Iranian households have had to contend with significant food inflation, even for staples such as bread. Considering that the negative humanitarian effects of sanctions are both persistent and systemic and have been long known to US officials, it is difficult to conclude that the effects are truly unintended.
