However, to what extent such games capture multiple food system components has yet to be established. We therefore conducted a systematic review of the literature on multiple food system component coverage in games and to assess their potential use in guiding sustainable food system transformation. We found 19 games that covered at least two food system components, of which eight addressed sustainable food system outcomes. Two of these games had the potential of covering rather all food system components and allowing reflection on economic, societal and environmental outcomes. Other games did not cover all components but did make either strong connections between the ones that were included or linked outcomes to multiple sustainability dimensions. For use in food system transformation, most games showed potential in transforming mindsets of a niche group of food system actors. However, only two could be played with a diverse group of stakeholders, of which one could additionally be applied in the political landscape. Future research should focus on further capturing system complexity within games to support imagining and evaluating effects of various strategies. By playing these games with different stakeholders, they could then have the potential to address the plurality of perspectives, cross disciplines and co-create strategies needed for food system transformation.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100864"},"PeriodicalIF":9.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerns over food security and agricultural decline have sparked widespread criticism of these transformations. However, the complex networks between DS and AP remain poorly understood. This study establishes association networks between DS and AP within urban-rural contexts, capturing geographic differences and interactions in Southwest China. AP is calculated using super-efficiency DEA and Bayesian network models estimate the complex associations between DS and AP. The results indicate that rapid aging and large-scale urban-rural migration are the primary DS trends in Southwest China. AP initially declined and then rose, with minor changes in scale efficiency. Bayesian networks confirmed the complex networks between DS and AP, showing that urban-rural migration and population aging are highly correlated with changes in scale and technical efficiency. From 2010 to 2020, urban-rural migration significantly enhanced the positive coupling between DS and AP, suggesting that DS has promoted AP development on a integral scale. However, the DS-AP association networks exhibit geographic differences across various topographical regions. In mountainous areas, population aging, and rural exodus have inhibited AP development, warranting extensive attention. This study's framework aims to achieve sustainable socio-ecological development through the benign coupling of DS-AP systems, supporting urban-rural governance and the sustainable development goals by refining the feedback and interaction processes of coupled social-ecological systems.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100867"},"PeriodicalIF":9.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local gender-biased norms further exacerbate gender-productivity gaps by undermining returns to women's endowments, and an intra-household old-age caring penalty disproportionately restricts their market participation.

The use of a binary designation also fails to capture the complexity and diversity of settlement types and results in a focus on the “rural-urban divide”. This study combines nationally representative survey data on household food consumption from eight West African countries with geospatial data capturing the urbanization gradient following the global definition of the Degree or Urbanization. This allows us to analyse consumption of different food groups, diet quality, and macronutrient intakes throughout the rural-urban continuum. We find robust evidence of an increasing rural-urban gradient in total food consumption, as well as a gradual shift away from traditional staple foods, towards increased consumption of foods that require less or no preparation. Residing in more urbanized areas is associated with greater diet diversity and increased consumption of vegetables and animal-source foods. Yet, rising intakes of unhealthy foods and fats in particular along the rural-urban continuum contribute to a deterioration of diet quality. While the estimated effects are strongest in cities, these diet transitions also take place in peri-urban areas and rural areas. This confirms the importance of moving beyond a simple rural-urban dichotomy in research and policy related to food consumption. The demonstrated importance of foods eaten away from home across the entire rural-urban continuum further underscores the need for more research to better understand this sector and explore how it can contribute to both employment and food security.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100858"},"PeriodicalIF":9.8,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In many regions of the world with intensive agriculture and relatively small yield gaps, this calls for a reduction of external inputs (fertilizers and pesticides) while maintaining yields. Ecological intensification, defined as the use of practices that enhance on-farm ecosystem services to reduce external input requirements, has been proposed as a strategy to help achieve this. However, the effects of ecological intensification are context- and input-dependent, creating uncertainty on its effectiveness and feasibility. Here, we introduce the concept of an ‘ecological yield gap’ to provide a common analytical framework to strengthen collaboration between agronomists and ecologists in assessing the contribution of ecosystem services within the wider array of inputs, management practices, technologies, and biophysical limits that determine on-farm crop yields. We define the ecological yield gap as the yield increase that could be achieved in a given context (climate x soil x cropping system), and at a given input level, by increasing the delivery of ecosystem services via ecological intensification practices that support crop growth and substitute external inputs. We provide empirical examples of such practices, including crop diversification, service crops, and organic amendments that can increase the use efficiency of mineral fertilizers and suppress pests, weeds and diseases. The potential of these practices to narrow the ecological yield gap and their feasibility at farm level depend on how the ecosystem services they provide interact with other aspects of the farming system and requires analysis at farm level. This perspective paper aims to facilitate a shared research agenda among agronomists and ecologists to develop complementarity between ecosystem services and inputs at field and farm levels.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100857"},"PeriodicalIF":9.8,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper quantitatively explores the nature of price shocks in fuel, fertilizer, and foods since 2019 and qualitatively characterizes the policy responses undertaken in six African countries, namely Ghana, Kenya, Nigeria, Senegal, Tanzania, and Zimbabwe. Results confirm that prices for key foods (maize, rice, wheat, and vegetable oil), fuel, and fertilizer increased markedly in all six countries, with the most rapid increases arriving in 2022. We completed a desk review of relevant policy responses and conducted 104 semi-structured interviews with policy makers and other key stakeholders across the six countries to understand their experiences with, and perspectives on, policy responses to recent and ongoing shocks. These interviews surfaced several themes: (1) Policies exhibit an intensifying emphasis since 2020 on self-sufficiency in food and fertilizer; (2) Though subsidies and tariff reductions are a readily available policy response, the fiscal burden can be quite high; (3) Policy responses to shocks sometimes lack coherence, with some policies offsetting the others’ impacts; (4) While recent shocks triggered some trade realignment, they have not stimulated increased within-Africa (intra-regional) trade; and (5) Policy makers exhibit an increasing appreciation for organic fertilizer and increasingly recognize climate change and associated environmental stress when shaping fertilizer policy. Altogether, these findings underscore a need for more discourse on the most fitting balance between national self-sufficiency and participation in international trade.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100861"},"PeriodicalIF":9.8,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
