The impacts of climatic conditions on cereal production: implications for food security in Africa

Climate change is a confounding factor that affects food security in several ways. Although the analyses of earlier studies in this area were largely non-technical, new analytical techniques have been developed to comprehensively evaluate climate change patterns and their implications for food security. In this study, we use recent developments in panel econometrics, which consider cross-sectional dependence and parameter heterogeneity, to examine the effects of climatic conditions on cereal farming in Africa from 1970Q1 to 2017Q4. The results show that rainfall positively affects cereal crops, although average temperatures are typically unfavourable. In the country-specific scenarios, we observed significant variations in the influence of climatic conditions on cereal production. The causality test results show a two-way causal relationship between climatic conditions-rainfall and temperature-and cereal production. It is suggested that African governments and non-governmental organisations support farmers' adaptation to climate change by implementing policies that prioritise farmers' capacity building and ensure that extension service officers engage with farmers intensively.

Navigating Infodemics, Unlocking Social Capital and Maintaining Food Security during the COVID-19 First Wave in the UK: Older Adults' Experiences

In March 2020, a national UK lockdown was implemented in response to rapidly rising COVID-19 infections. Those experiencing the most severe public health restrictions were ‘shielding’ groups as well as those over 70 years of age. Older age adults, many of whom were active, independent, and socially connected were immediately instructed to stay at home, to limit all external social contact and consider contingency for maintaining personal food security and social contact. The purpose of this qualitative study was to explore the experiences of older adults during the first UK lockdown (March–June 2020), specifically how our sample reacted to public health messaging, staying food secure and drawing on available social capital within their community. Semi-structured telephone interviews were conducted with eight participants. In addition, twenty-five participants completed a qualitative ‘open-ended’ survey. The data was collated and analysed, adopting a Thematic Analysis informed approach. Three themes were identified: (1) Too Much Information, (2) The Importance of Neighbours and Connections and (3) Not Wishing to be a Burden. These findings offer a rich insight into how early lockdown measures, never witnessed since World War 2, exposed existing pre-pandemic inequalities and concerns relating to loneliness, isolation and wellbeing. The findings are of relevance to researchers, older adult advocate groups and policy makers to inform post COVID-recovery within communities to ensure healthy ageing.

Welfare State Spending, Income Inequality and Food Insecurity in Affluent Nations: A Cross-National Examination of OECD Countries

Few studies examine the distribution of food insecurity in advanced capitalist nations. This research investigates cross-national food insecurity in the world’s largest economies by estimating the impact of welfare spending and income inequality on food availability (measured by the FAO’s Dietary Energy and Protein Supply indicators) and food accessibility (measured by the Food Insecurity Experience Scale) in 36 Organization for Economic Cooperation and Development (OECD) countries between the years of 2000 and 2018. Using a series of regression models on panel and cross-sectional data this research found that increases in state spending on social and health care are associated with (1) increases in food availability and (2) increases in food access. However, the findings also suggest that increases in food supplies do not produce more food security. Thus, for the OECD countries in this analysis, food availability is unrelated to food accessibility. We conclude by suggesting that high income countries that seek to promote global health should not only focus their efforts on poverty reduction polices that increase food accessibility within their own boarders, but must simultaneously ensure a more equitable global distribution of food.

The association between family structure and children's BMI over time-the mediating role of income

PURPOSE

Although both family structure and income have previously been indicated as being associated with body mass index (BMI), the extent to which the effect of family structure on BMI is mediated through income is incompletely understood. Taking the case of the United Kingdom, this study aims to investigate the association between family structure, defined in this study as whether children live in a one- or two-adult household, and childhood BMI, and whether this varies by child sex and with increased age. Second, the study aims to examine whether family equivalised income, as a proxy for socioeconomic status, mediates the association between family structure and childhood BMI.

METHODS

This study uses data from the Millennium Cohort Study. Data from 7478 children born between 2000 and 2001 in the UK at the ages of 3, 5, 7, 11, and 14 were used. Mediation analysis was used to consider, at each age, the extent to which the association between living in a one- or two-adult household and BMI was mediated through income overall and stratified by sex. To assess the robustness of the mediation analysis estimates, we used both E-values and multiple confounder adjustment.

RESULTS

At ages 3 and 5, there was no direct or indirect effect of family structure mediated by income on BMI. Between the ages of 7 and 11, the overall proportion of the association mediated vastly increased, from 19.70% at age 7 up to 42.70% at the age of 11. The E-values show that substantial unmeasured confounder associations would be needed to fully explain away the conclusions from the mediation analysis. Results remained significant when models were additionally adjusted for geographic region, the main respondent's (usually the mother's) highest educational attainment, and ethnicity.

CONCLUSIONS

An increasing proportion of the association between family structure and BMI is mediated by income as children grow older. The study focuses on the mediating role of income between family structure and BMI using the available data as an empirical application of the potential impact of income as mediator in the causal pathway.

Measuring Food Insecurity Using the Food Abundance Index: Implications for Economic, Health and Social Well-Being

High levels of food insecurity signal the presence of disparities and inequities in local food access, which have been shown to negatively impact the health and well-being of individuals and communities. However, the approaches used to define and measure high food insecurity, also known as a "food desert", vary widely across research study and intervention methodology. This paper describes the development and validation of a measurement tool called the "Food Abundance Index" (FAI) which is a scorecard for assessing levels of food insecurity across five key dimensions: access, diversity, quality, density, and affordability. A pilot study was conducted to examine levels of food insecurity in order to test the extent to which the FAI can detect food deserts. Nine neighborhoods were selected based on the demographic characteristics of communities shown to be related to food insecurity. Our findings provide evidence that the Food Abundance Index provides a robust measurement tool to assess the extent of food insecurity within a community or neighborhood. Thus, this multidimensional scorecard can be used in future research to detect levels of food insecurity within urban areas and help to bridge the gap between academics, policymakers and practitioners in this important area.

Factors Associated with Food Insecurity Following Hurricane Harvey in Texas

Food insecurity prevalence among disaster-affected households has been found to be higher than state prevalence in non-disaster times. This study applies a socio-ecological model of post-disaster food insecurity to a nested quota sample (n = 1002) recruited for a web survey from 41 Texas counties affected by Hurricane Harvey 12-15 months post-event. This analysis identifies risk and protective factors for food insecurity. Chi-square analysis was used to examine independent associations between individual, household, and social factors with food insecurity. A multivariate logistic model was fitted and adjusted odds ratios are reported. Economic instability (adjusted odds ratio (OR) 2.43; 95% Confidence Interval (CI) 1.73, 3.41), relocation due to Hurricane Harvey (OR 1.89; CI 1.15, 3.09), major home damage (OR 2.11; CI 1.12, 3.98), non-white race - black (OR 1.79; CI 1.01, 3.18), Hispanic (OR 1.67; CI 1.09, 2.54), other race (OR 4.39; CI 1.96, 9.82) - and community-based organization assistance (1.99; 1.11, 3.58) were risk factors while older age (45-64 years: 0.49; 0.32, 0.73; 65+ years 0.40; 0.22, 0.75), better physical health (0.46; 0.29, 0.71), better mental health (0.46; 0.32, 0.67), and high social support (0.37; 0.25, 0.55) were protective against food insecurity. Disaster policies and programs should address the disproportionate burden on households that relocate or have health conditions. Fostering social support networks, especially among relocated populations, may improve disaster health outcomes.

Exploring the Experiences of West African Immigrants Living with Type 2 Diabetes in the UK

The increasing prevalence and poorer management of Type 2 diabetes among West African immigrants in the UK is a public health concern. This research explored the experiences of West African immigrants in the management of Type 2 diabetes in the UK using a constructivist grounded theory approach. In-depth individual interviews were conducted with thirty-four West African immigrants living with Type 2 diabetes in the London area. Fifteen male and nineteen female adult West African immigrants with age range from 33-82 years participated in the study. Participants were recruited from five diabetes support groups and community settings. Initial, focused and theoretical coding, constant comparison and memos were used to analyse collected data. Three concepts emerged: Changing dietary habits composed of participants' experiences in meeting dietary recommendations, improving physical activity concerned with the experience of reduced physical activity since moving to the UK and striving to adapt which focus on the impact of migration changes in living with Type 2 diabetes in the UK. These address challenges that West African immigrants experience in the management of Type 2 diabetes in the UK. The findings of this research provide a better understanding of the influencing factors and can be used to improve the support provided for West Africans living with Type 2 diabetes in the UK, presenting a deeper understanding of socio-cultural factors that contribute to supporting individuals from this population.

Addressing Food and Nutrition Security in Developed Countries

The guest editors of the special issue on Addressing Food and Nutrition Security in Developed Countries reflect on the 26 papers that were published as part of this issue and the scope of research contained therein. There is an extensive body of work, which focuses on topics ranging from the prevalence of food insecurity in developed countries, associations and determinants, measurement and monitoring, to reports of the lived experience and coping strategies of people who are living with food insecurity or and those who are a part of the charitable food sector. Very few solutions to address the problem of food insecurity in developed countries were offered, and many challenges highlighted. Further research is required to find the solutions to address the problem of food insecurity in developed countries, and important principles and values are proposed for those undertaking this work to embrace.

Food Insecurity and Hunger in Rich Countries-It Is Time for Action against Inequality

Household food insecurity is a serious public health concern in rich countries with developed economies closely associated with inequality. The prevalence of household food insecurity is relatively high in some developed countries, ranging from 8 to 20% of the population. Human rights approaches have the potential to address the structural causes, not just the symptoms of food insecurity. Despite most developed countries ratifying the Covenant on Economic, Social and Cultural Rights over 40 years ago, food insecurity rates suggest current social protections are inadequate. The contemporary framing of the solution to food insecurity in developed countries is that of diverting food waste to the hungry to meet the United Nations Sustainable Development Goals agenda (Goals 2 and 12.3). An estimated 60 million people or 7.2% of the population in high income countries used food banks in 2013. Although providing food assistance to those who are hungry is an important strategy, the current focus distracts attention away from the ineffectiveness of government policies in addressing the social determinants of food insecurity. Much of the action needed to improve household food security falls to actors outside the health sector. There is evidence of promising actions to address the social determinants of food insecurity in some developed countries. Learning from these, there is a strong case for government leadership, for action within and across government, and effective engagement with other sectors to deliver a coordinated, collaborative, and cooperative response to finding pathways out of food insecurity.
