1. Meta-analysis of the impacts of digital information interventions on agricultural development.
PMID:日期:2025-06-01Digital means of delivering advisory and other information services to small-scale agricultural producers are widely expected to expand the reach of extension and other information provision services while reducing costs. However, there is currently little evidence systematically quantifying these benefits. In this paper, we synthesize quantitative information on the impacts of digital information interventions, which may integrate human support, on adoption of modern farm inputs (fertilizer and improved seeds), yield, and income, covering interventions implemented between 2005 and 2019. Our starting point for the meta-analysis was the Agriculture in the Digital Age Evidence Gap Map dataset, which provided a consistent set of studies of digital interventions, though one limitation is that it excludes more recent studies published after 2021. After applying our criteria for relevance, rigor, and availability of necessary data, we used estimates from 20 studies in our analyses where fifteen were from Sub-Saharan Africa, four from India, and one from Cambodia. Mean impacts of digital information interventions on adoption of fertilizer (+23 %; 95 % CI +6 % to +40 %), yield (+6 %; +2 % to +9 %), and income (+6 %; +2 % to +9 %) are positive while effects on adoption of improved seeds were not statistically significant. Although our analysis indicates that digital farmer services have provided benefits on average, there is considerable variability in estimates across individual studies. However, there are not enough comparable quantitative observations from the literature included within our study population to reliably further disaggregate estimated impacts (e.g., by intervention, level of human assistance, geography, modality of information delivery, farmer type). Expansion of the available evidence base to facilitate quantification of these heterogeneous impacts is needed to better inform program design to maximize effectiveness.

2. Severe food insecurity among middle-aged and older adults in India: Insights from the Longitudinal Aging Study in India.
PMID:日期:2025-03-01Severe food insecurity (SFI) is a critical concern in India, yet few studies have highlighted national and state trends among Indian adults. Utilizing data from 63,525 adults aged 45 and above from the Longitudinal Aging Study in India (2017-18), we present noteworthy geographic and sociodemographic patterns in the distribution of SFI. We estimate the national prevalence to be 6.2% (95% CI: 5.6, 6.8). Madhya Pradesh had the highest prevalence of SFI (10.3%), followed by Jharkhand, Tamil Nadu, and Bihar. Conversely, Nagaland, Goa, Lakshadweep, and Arunachal Pradesh had the lowest prevalence (all under 2.0%). Living in a rural area, being widowed, belonging to a Scheduled Caste, and being Muslim were positively associated with reporting SFI. Additionally, those in the middle and richer household monthly per capita expenditure quintiles, with 6-9 years of schooling, who resided in the country's northern and northeastern regions, or who had never worked for more than three months in their lifetime, were less likely to report SFI. We also find that geography and socioeconomic status synergistically affect SFI. Specifically, adults with lower levels of education were at a greater risk of SFI in rural areas, relative to urban areas, and the Central and East regions of India, relative to the North. Our findings highlight the need for robust state-level policies to ensure equitable access to affordable, high-quality food for all Indian adults, particularly for those belonging to at-risk groups.

3. Global review of consumer preferences and willingness to pay for edible insects and derived products.
PMID:日期:2025-03-01The rising global demand for protein, driven by population growth, urbanization, economic development, and climate change, underscores the need for sustainable alternative protein sources. Edible insects have emerged as a viable solution to enhance foodfeed and nutritional security while contributing to waste management. This study reviews 128 peer-reviewed publications to assess consumer preferences and willingness to pay (WTP) for edible insects and their derivatives. Findings reveal that studies predominantly focus on Europe and insect-based foods, with limited research on insect-based feeds and derived products. Consumers in Africa, Asia, and Latin America show higher acceptance of insect-based food compared to those in Western nations, where psychological barriers such as neophobia, disgust, and limited awareness hinder adoption. WTP for insect-based foods varies, with some consumers willing to pay a premium while others expect lower prices than conventional options. Integrating edible insects into sustainable food and feed ssytems requires public education, innovative marketing, and scaling up production.

4. Global analysis reveals persistent shortfalls and regional differences in availability of foods needed for health.
PMID:日期:2025-03-01Sufficient food is available in the world for all people to consume sufficient calories, but not healthy diets. This study traces historical and projected changes in global food systems toward alignment with the new Healthy Diet Basket (HDB) used by UN agencies and the World Bank to monitor the cost and affordability of healthy diets worldwide. Using the HDB as a standard to measure adequacy of national, regional and global supply-demand balances, we find substantial but inconsistent progress toward closer alignment with dietary guidelines, with large global shortfalls in fruits, vegetables, and legumes, nuts, and seeds, and large disparities among regions in use of animal source foods. Projections show that additional investments aimed at reducing chronic hunger would modestly accelerate improvements in adequacy where shortfalls are greatest, revealing the need for complementary investments to increase access to under-consumed food groups especially in low-income countries.

5. Expanding the food environment framework to include family dynamics: A systematic synthesis of qualitative evidence using HIV as a case study.
PMID:日期:2024-09-01Food environment changes in low- and middle-income countries are increasing diet-related noncommunicable diseases (NCDs). This paper synthesizes the qualitative evidence about how family dynamics shape food choices within the context of HIV (Prospero: CRD42021226283). Guided by structuration theory and food environment framework, we used best-fit framework analysis to develop the Family Dynamics Food Environment Framework (FDF) comprising three interacting dimensions (resources, characteristics, and action orientation). Findings show how the three food environment domains (personal, family, external) interact to affect food choices within families affected by HIV. Given the growing prevalence of noncommunicable and chronic diseases, the FDF can be applied beyond the context of HIV to guide effective and optimal nutritional policies for the whole family.

6. Eating on the move: experiences of food insecurity and hunger during overland transit through Mexico.
PMID:日期:2024-09-01To explore migrants' experiences of food insecurity during their overland transit through Mexico, using qualitative methods. We conducted a qualitative study (May - July 2016) of 26 Central American migrants in a migrant shelter in San Luis Potosí, México. The semi structured interview explored four domains of food insecurity: 1) availability; 2) accessibility; 3) utilization (eating practices and consumption; and 4) stability (experiencing hunger). Participants shared common food choices and reasons for selecting these foods. These included properties such as ease of transportability, storage (e.g., packaging) and preparation needed prior to intake (e.g., whether cooking was required). Shelters provided access to humanitarian assistance including food. The informants also experienced hunger and multiple challenges impeding their physical access to food. These were further aggravated by the disadvantaged socioeconomic conditions of areas through which they transited. Migrants transiting overland through Mexico experienced challenges that limit availability, access, consumption, and stability of food, showcasing the critical nature of providing food security to ensure their human rights.

7. Divergent beliefs about food safety and affordability in Nigeria.
PMID:日期:2024-06-01Access to safe, affordable diets is paramount for improved nutritional outcomes. Yet, how do stakeholders perceive the binding constraints and requisite policy actions to increase food safety and affordability? Focusing on Nigeria, this paper uses best-worst scaling techniques applied to a survey of 200 government and agrifood system stakeholders to examine their policy beliefs on safety and affordability vis-à-vis the vegetable and fish value chains. We find that divergence among stakeholders is greater for food safety than affordability. While antibiotics overuse and toxin exposure, lack of knowledge, and weak legislation were identified by different stakeholders as the binding constraints for food safety, high costs of inputs and infrastructure, as well as security threats, were seen as common challenges for affordability across most, though not all, stakeholders for both value chains. Overall, the paper highlights the importance of beliefs in the agrifood system policymaking process and emphasizes the need to explore not only the existence but also the source of divergent beliefs among policy actors in greater depth.

8. Domestic and international impacts of rice export restrictions: The recent case of indian non-basmati rice.
PMID:日期:2024-06-01This study examines the impact of India's export restrictions on domestic retail rice prices using a dynamic panel GARCH model. The findings suggest that export restrictions are not a sufficient condition to lower domestic prices. Export restrictions are associated with lower retail price volatility in the East Zone. Moreover, the international price transmission to a sample of Asian and African economies shows that all countries are vulnerable, but the degree and kinds of vulnerability differ. Rice exporters appear to be the most susceptible as domestic prices increase in these countries. Rice importers are also vulnerable because of price increases, but the increases are less than in countries where the private sector decides on import quantities.

9. Measuring food access using least-cost diets: Results for global monitoring and targeting of interventions to improve food security, nutrition and health.
PMID:日期:2024-06-01Benchmark diets using the most affordable locally available items to meet health and nutrition needs have long been used to guide food choice and nutrition assistance. This paper describes the result of recent innovations scaling up the use of such least-cost diets by UN agencies, the World Bank, and national governments for a different purpose, which is monitoring food environments and targeting systemic interventions to improve a population's access to sufficient food for an active and healthy life. Measuring food access using least-cost diets allows a clearer understanding of where poor diets are caused by unavailability or high prices for even the lowest-cost healthy foods, insufficient income or other resources to acquire those foods, or the use of other foods instead due to reasons such as time use and meal preparation costs, or cultural factors such as taste and aspirations. This paper reviews the data, methods and results that have led to official FAO and the World Bank adoption of cost and affordability metrics for global monitoring, and the parallel use of similar methods to guide interventions in country studies led by the World Food Programme with partner agencies across Africa, Asia and Latin America. We conclude by summarizing how increasing availability of food price data, matched to food composition and dietary requirements, allows analysts to use recently developed software tools for least-cost diet assessment to improve food access in a wide range of settings.

10. Enabling food system innovation: accelerators for change.
PMID:日期:2024-03-01It is widely accepted that current food systems are not on a trajectory for achieving the Sustainable Development Goals by the end of the decade. Technological innovation will have a considerable role to play in different parts of the food system; many promising options exist or are in the pipeline, some of which may be highly disruptive to existing value chains. Scaling up the innovations required, at the same time as protecting those who may lose out in the short term, will require a strong enabling environment. Here we apply an existing framework of eight change accelerators to six case studies of historical agricultural innovation. We estimated the degree to which each accelerator had been addressed at some stage in the innovation process, as a measure of the gap between what was needed and what was achieved. For the innovations that are being taken to scale and widely utilized, these accelerator gaps are small. Uptake of other innovations is stalled, and for these we found large gaps for one or more of the eight accelerators. Impactful innovation processes address all eight change accelerators at some point, with different phasing of the accelerators depending on the nature of the technology and on the impact pathway being pursued. This simple framework, when used in combination with narratives of uptake based on theories of change and impact pathways, may provide an effective means of screening future innovation processes to help prioritize and guide investment that can lead to more resilient, sustainable and equitable food systems.
