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}

These include the Covid-19 pandemic, the Russia-Ukraine War, and manifestations of climate change, among others. 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}

Closing gender gaps and increasing women's empowerment in agrifood systems is critical to achieving a broad range of objectives, including Sustainable Development Goals 1, 2, 5 and 10. Much of the literature on women's empowerment in agriculture and agrifood systems focuses on its benefits in terms of agricultural production, dietary diversity, child nutrition and women's nutrition. However, there is limited evidence on the impact of women's empowerment on outcomes related to livelihoods and resilience to shocks -- two key elements that drive improvements in the livelihoods of small-scale producers and help to further justify the importance of investing in women's empowerment to achieve development outcomes. This paper aims to bridge this gap by examining how women's empowerment within development projects in the agriculture and rural development sectors affects household livelihood outcomes including income, food security/nutrition and resilience. Utilizing a comprehensive dataset from the International Fund for Agricultural Development (IFAD) across 23 countries worldwide, we assess the role of empowering women in improving livelihoods for their households. Our analysis employs a dual approach: a meta-level evaluation focusing on project outcomes and a household-level analysis aggregating data from 21 of the 23 countries available. Results from both analytical methods reveal significant benefits to livelihood outcomes, including enhanced household income and resilience, where women report increased empowerment.
