China, the world’s second most populous country, has long prioritized food security in national strategies, and is actively promoting a transition towards a sustainable agri-food system. However, the understanding of China’s food security governance and its integration of sustainability considerations remains fragmented. This review employs a systematic policy mapping approach to analyze the evolution of China’s food security policy framework, with particular attention to its integration with environmental protection and land-use management. By extracting and organizing policy measures from 1971 to 2025, the policy review reveals a steady policy transition toward sustainable and resilient food systems. Food supply has diversified beyond cultivated land, with a rising prominence of grassland agriculture that prioritizes ecosystem services over mere production. Since 2000, environmental protection has been systematically embedded into food security governance, with water, soil, and biodiversity as core priorities under an integrated prevention-protection-restoration governance mode. Land-use policies continue to center on cultivated land protection, complemented by spatial optimization. Spatial optimization has evolved into a foundational principle of land-use management, supporting the coordinated planning of cultivated land and grassland for reconciling production and environmental goals. The observed increase in policy integrations is enabled by a broadening array of policy actors engaging in cross-sectoral coordination. China’s food security policy agenda has embarked on a more holistic and sustainable food systems transformation pathway, providing valuable insights and references for other countries seeking similar integrated governance.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1691 - 1707"},"PeriodicalIF":4.5,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01696-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This requires a systemic approach that considers the entire food supply chain and the crucial role which cities and urban policies can play in influencing food systems transition. While cities are pioneering many local innovations, scaling these towards a transition remains a challenge. This longitudinal study followed eleven European cities working on local food agendas and associated innovations for a period of three years. The study examines barriers and drivers for upscaling and outscaling urban food systems innovations, providing insights for successful strategies for urban policy makers to promote a transition towards sustainable, resilient urban food systems. The analysis shows how cities struggle with fragmentation in policy and budget structures, often relying on short-term funding for food-related projects. Strong political commitment, dedicated budgets, cross-departmental integration and stakeholder collaboration drive change. Cities with formal food policies, strong local political support, and active stakeholder networks achieve greater impact. Engaging diverse stakeholders and investing in human capacity leverages resources, promotes knowledge exchange, and supports scaling. Flexible, context-sensitive governance outscaling strategies help tailor initiatives to local conditions and adapt to evolving local contexts. But transforming food systems also requires a long-term vision, which ideally embeds food policy into broader urban agendas ensuring stable funding and leveraging local partnerships. Long-term strategies, continuous learning, and adaptive governance are essential to sustaining food systems innovations beyond project cycles, fostering resilient and sustainable urban food environments.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1639 - 1653"},"PeriodicalIF":4.5,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01691-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly for low- and middle-income countries dependent on domestic agriculture and low-cost food imports, evaluating the access to healthy diets is crucial to meeting food security goals. This paper provides the most expansive poverty assessment using the cost of basic needs approach in Papua New Guinea (PNG) in 15 years. In doing so, we compare a standard cost of basic needs poverty line where the food poverty line is defined by modest diets aligned with consumption patterns that meet a dietary energy (calorie) threshold; and a healthy diet food poverty line that meets both the dietary energy threshold and recommended nutrition targets. Results suggest that 43% of sample individuals live below the standard cost of basic needs poverty line. An additional 21% of sample individuals (64%) live below the healthy diet poverty line due to the relatively high cost of nutrient-dense foods in PNG. Multivariate regression analysis underscores the importance of household income diversification, whether via non-farm enterprise ownership or migrant remittances. Results reflect the unique challenges characterized by PNG’s remote landscape and lack of rural services, amplifying the need to improve rural-urban linkages that promote market access, educational attainment, and higher value employment opportunities.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1443 - 1463"},"PeriodicalIF":4.5,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01694-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spatial accessibility was measured using population-based indicators of outlet density within walkable distances, and associations with socioeconomic and urban structure variables were analyzed using spatial autocorrelation and regression models. Food outlets were strongly concentrated in central, consolidated urban areas, with both healthy and unhealthy establishments following similar spatial patterns. Areas classified as food deserts were mostly located in peripheral zones with lower overall commercial density, while food swamps were more widely distributed. Access to healthy food outlets was positively associated with income and urban consolidation, and negatively associated with peripheralization and distance to arterial roads. However, classifications of food deserts and food swamps proved highly sensitive to methodological choices and closely aligned with broader patterns of urban structure. In a context of generally high spatial accessibility, these metrics appear to capture relative differences in commercial density rather than absolute constraints on food access. These findings suggest that density-based spatial indicators should be interpreted with caution, as they may more reflect underlying socio-spatial organization, rather than meaningful inequalities in access to food.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1545 - 1557"},"PeriodicalIF":4.5,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01697-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we combine a lab-in-the field experiment with survey data from Cameroon to analyze how spousal cooperation relates to household, children’s, and women’s dietary quality. Spousal cooperation is measured in terms of husband’s and wife’s budget allocations to a public goods game. Regression results reveal a robust U-shaped association: the marginal effect of cooperation on dietary quality is negative but declining in absolute magnitude for levels of cooperation from 0 to 0.7, at which point it becomes positive. That no cooperation is associated with better dietary outcomes than low and medium cooperation is unexpected. Possibly, no cooperation reflects separate spheres between husband and wife, which may not always be bad for dietary outcomes if women have own income that they can spend on healthy nutrition for their family. In contrast, low to medium cooperation may reflect role ambiguity and conflict, resulting in lower dietary quality. High cooperation may indicate more trust and harmony between spouses, which can plausibly lead to better dietary outcomes. Some of our findings challenge conventional wisdom. Further research is needed to explain the underlying mechanisms. This should also include work on how to measure the various nuances of spousal cooperation that likely matter in different contexts.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1407 - 1419"},"PeriodicalIF":4.5,"publicationDate":"2026-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01692-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A filtering approach was used to ensure a representative sample. We evaluate the likely accuracy of the data by triangulating the responses with high-frequency data from our own face-to-face household surveys as well as externally collected phone survey data. The analysis suggests that SMS-based surveys can be a promising tool to measure changes in food security status over time but perform less well with regard to measuring the actual food security status. Responses related to the general food situation (rather than dietary diversity, food consumption or market prices) emerged as the most reliable indicator.

However, domestic production covers only about 60% of the demand, increasing vulnerability to climate shocks and global market volatility. With limited potential to expand cultivated area, national food security increasingly depends on how effectively breeding-derived genetic gains translate into farm-level performance. While breeding programmes achieve yield gains of about 59 kg ha⁻¹ yr⁻¹, only roughly 31% is realised in farmers’ fields, indicating major inefficiencies along the seed pathway. This limited realization is associated with a low varietal turnover rate (≈0.045 yr⁻¹), a modest seed replacement rate (≈35%), and a prolonged adoption lag of 10–12 years. This review applies a systems-diagnostic framework to examine the structure, performance and constraints of Morocco’s wheat seed system, drawing on peer-reviewed literature, institutional analyses and policy documents. The assessment evaluates governance, regulatory processes, early-generation and certified-seed supply, and adoption dynamics, using varietal turnover rate, seed replacement rate and genetic-gain realisation to characterise system efficiency. The review finds that despite strong varietal integrity and quality control, the overall performance of Morocco’s wheat seed system is limited by centralised governance, protracted registration and licensing procedures, insufficient private-sector engagement and weak coordination between breeding, certification and extension. These constraints slow varietal renewal, restrict seed availability and diminish the expression of genetic progress. Strengthening Morocco’s food security will require modernising varietal registration, expanding seed-production capacity, realigning subsidy incentives and fostering public–private collaboration. Building on insights from Hall’s studies of seed-system innovation in Morocco, lasting improvement will depend on strengthening the institutional linkages, learning mechanisms and collaborative capacities that enable breeders, regulators, seed producers, and farmers to innovate together.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1675 - 1690"},"PeriodicalIF":4.5,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Sahel, and specially in Niger, increasing climate stress is compounded by episodes of civil unrest that erode household livelihoods and reduce their capacity to meet basic needs. Identifying household strategies that reduce sensitivity to temperature anomalies and conflicts is therefore critical for strengthening food security. This paper links spatially granular climate data (temperature and NDVI (Normalized Difference Vegetation Index)) and conflict events with four Living Standards Measurement Study rounds in Niger to evaluate how climate and conflict affect Household Dietary Diversity Score (HDDS). NDVI is used as a proxy for vegetation health and agricultural production potential; only negative anomalies are considered to isolate the effects of adverse growing conditions on food security. We estimate household fixed-effects models and interact climate and conflict measures with indicators of adaptation and resilience (organic fertilizer use, crop diversification, diversified income sources, electricity access, and receipt of assistance) to test whether these strategies mitigate adverse impacts on the HDDS. Results show that high temperature, lower NDVI, and local episodes of civil unrest are each associated with statistically significant declines in HDDS. Importantly, households that apply organic fertilizers, diversify crops, diversify income sources, have electricity access, or receive external assistance experience smaller losses in dietary diversity following climate stress and conflict events. Additionally, income sources diversification reduces the negative effects of climate and conflicts. These findings imply that promoting sustainable agricultural practices, supporting income diversification into less climate-sensitive activities, and scaling targeted assistance are effective options to bolster household resilience to the dual challenges of climate stress and conflict in Niger. The application is wider beyond the Sahel region.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1581 - 1597"},"PeriodicalIF":4.5,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that most farms were jointly managed by women and men, and jointness in plot management has increased over time, highlighting the critical need to examine jointness in decision-making and intrahousehold relations. 20% of sampled rural women did not achieve empowerment; main contributors to their disempowerment were lack of group membership and lack of access and control over financial resources. Results also show that women’s education and their access to extension services are significantly associated with empowerment. Women’s empowerment indicators significantly explain some variations in crop productivity, as well as variations in some food security and dietary diversity indicators. The heterogeneity analysis shows that the magnitude of association between women’s empowerment and crop productivity is similar across asset quintiles and age groups, but the magnitude of association between women’s empowerment and food security is much smaller among households in the middle asset quintile than in the poorest and wealthiest quintiles.
