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. This suggests that women's empowerment is a key area of investments for rural development and prosperity.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100856"},"PeriodicalIF":9.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839468","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}

An explanation that has been advanced in the literature lies in unfair food distribution within a specific region. However, empirical evidence regarding how infectious diseases influence people's food availability from a global food distribution perspective is still lacking. This paper aims to provide empirical evidence through investigating the effect of infectious diseases on hunger from the perspective of global food distribution. Using a panel data for 105 countries over the period of 1990–2016, we find that infectious diseases had no significant impact on overall global food production, but they caused more severe hunger in many countries or regions. How is that possible? The mechanism analysis shows that there was an increased flow of food from developing countries to developed countries during epidemics. Meanwhile, developing countries failed to compensate for this shortfall through either food stock or food aid, resulting in a reduced availability of food for domestic consumption. We find that epidemics caused higher domestic food prices and reduced affordability of food, which further exacerbated food insecurity and malnutrition in developing countries. To achieve the 2030 SDGs goal of Zero Hunger, it is critical to improve global food governance and enhance food distribution when facing a crisis such as epidemics.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100848"},"PeriodicalIF":9.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839469","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}

Simultaneously, the US is in a trade deficit, importing three times as many fruits and vegetables as it exports. Those fruits and vegetables that are produced in the US rely on precarious labor systems and unsustainable costs to the wellbeing of farmers and farmworkers, exposing the fractures and precarity of these systems amidst changing trade agreements and immigration policies. To overcome these fractures, calls for more diverse and resilient food systems are increasingly urgent. Using national-scale agricultural and labor datasets, we ask: 1) How well do current US agricultural landscapes produce the fruits and vegetables needed for a healthy and diverse diet <em>at scale</em>? 2) How diverse are these landscapes? 3) How does migrant labor support fruit and vegetable production and diversity? We show that US agricultural landscapes are not producing the fruits and vegetables needed for a healthy and diverse diet. Fruit and vegetable production is concentrated on the coasts of the country and occupies little land, making it difficult to see, track, and understand on a national scale. Further, as the proportion of cropland under fruit and vegetable production increases, fruit and vegetable diversity decreases, suggesting that most fruits and vegetables are grown in simplified systems. Finally, counties with the highest proportion of fruit and vegetable production have the highest averages of H-2A farmworker certifications, emphasizing a disproportionate reliance on migrant labor as fruit and vegetable production expands. This study helps to disentangle the link between what we grow and what we eat in the US, tempering calls to increase fruit and vegetable production in the US writ large without reconciling the accumulating concerns of these current systems.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"45 ","pages":"Article 100860"},"PeriodicalIF":9.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829876","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}
