The COVID-19 pandemic has caused many households to experience income shocks because of the unprecedented job loss, resulting in the demand for public and private food assistance programs and a surge in unemployment insurance filing in the USA. This study aims to investigate the association between social safety programs (e.g. supplementary nutritional assistance programs (SNAP), unemployment insurance and charitable food assistance) and household food sufficiency during the COVID-19 pandemic in the country.

The authors used the Household Pulse Surveys (HPS) conducted by the US Census Bureau from August 2020 to March 2021. And, the authors used an ordered probit model for the empirical analysis because the indicator of food sufficiency constructed from the HPS is an ordinal variable with four categories. The indicator identifies four groups of households: severe food insufficiency, moderate food insufficiency, mild food sufficiency and food sufficiency.

The results show that food sufficiency is significantly higher among the SNAP, unemployment insurance and charitable food assistance recipients than non-recipients. Furthermore, the results indicate that food sufficiency is significantly lower among black, Asian, Hispanic and other races than white households. Concerning the intersectional effect of social safety net programs and race/ethnicity on household food sufficiency, the authors find that the household food sufficiency is significantly higher among white, black and Asian households who benefited from SNAP, compared with non-beneficiary households. On the other hand, the authors find no evidence that participation in SNAP increases food sufficiency significantly among Hispanics and other races. In addition, the likelihood of food sufficiency increases significantly among white, black, Asian, Hispanic and other races that received unemployment insurance and charitable food assistance during the COVID-19 pandemic compared with those who did not benefit from the programs.

These results underscore the critical role collective America’s social safety net programs played in increasing food sufficiency among Americans during the COVID-19 pandemic. Specifically, the results suggest that families' basic needs (food sufficiency) would have been at risk if these safety net programs were not available to households during the pandemic. This, therefore, highlights the important role that government- and non-government-supported food emergency assistance programs can play in preventing people from facing food insufficiency problems in a tough time or during a crisis in the USA.

This study highlights the dynamic relationship between Americans’ social safety net programs and household food sufficiency during the COVID-19 pandemic.

This study aims to investigate the causal relationship between nutrition and economic growth in sub-Saharan Africa.

A dynamic panel causality test based on the Blundell-Bond’s system generalized methods-of-moment was used. To make efficient inference for the estimates, the authors check for the panel unit root and co-integration relationship amongst the variables.

The variables were found to be non-stationary at level, stationary after first difference and co-integrated. The results of the causality tests reveal evidence of long and short-run bidirectional causality between nutrition and economic growth, which implies that nutritional improvement is a cause and consequence of economic growth and vice versa.

This is the first study to consider causality between nutrition and economic growth in the region.

The purpose of this paper is to use cross-country data to investigate whether convergence process exists in per capital nutrient supply and also identify the determinants of change in per capita nutrient supply in sub-Saharan Africa (SSA).

Annual time series data for 43 countries covering 1975-2009 that yields balanced panel were employed for the analysis. The convergence hypothesis is examined based on the neoclassical growth model using feasible generalized least square approach that is robust to autocorrelation and cross-sectional dependence.

The empirical results lend support to existence of convergence process in nutrient supply in SSA. Evidence of convergence in nutrient supply may have contributed to observed reduction in incidence of food-poverty in the region, which aligns with the argument in literature that recent Africa food security gains are due to food imports. The results of the determinants of change in nutrient supply showed that, global food trade represented by trade openness consistently increased growth in nutrient supply across countries in SSA significantly. Meanwhile, the speed of convergence of per capita nutrient supply, which measures how quickly growth in nutrient supply increases over time is very low, as this calls for urgent policy attention in the region.

The very first study to investigate convergence in food consumption and nutritional supply in SSA.

The purpose of this paper is to revisit the Environmental Kuznets Curve (EKC) model in Sub-Saharan Africa (SSA) countries by focusing on two indicators of environmental change (EC), namely rate of deforestation (RD) and all greenhouse gas emissions from agriculture (Agric_GHG) with aim of addressing two key objectives in the study. First, to investigate whether the EKC hypothesis exists for both indicators considered in the region. Second, to examine the effects of macroeconomic and institutional variables on both indicators in the study.

The authors employ a balanced panel data covering 43 countries from 1990-2009 in the study. Subsequently, the study uses serial correlation/autoregressive order one corrected cross-section time series model based on Feasible Generalized Least Square method.

The empirical results show that the EKC exists (i.e. as inverted U-shaped) only for all GHG emissions from agriculture. Agricultural production and trade openness increase significantly both indicators of EC considered in the study. Other results show that, population growth reduces significantly Agric_GHG, while economic growth increases significantly RD in SSA.

This is the very first study to investigate the applicability of EKC hypothesis to emissions from non-oil sector such as agriculture (i.e. all GHG emissions from agriculture) in the region.

The economic recession that Nigeria recently passed through caused distortions in economic and well-being of Nigerians. The purpose of this paper is to examine the effects of the economic recession on households’ demand for basic foodstuffs in Southwest Nigeria.

Data were collected from 380 respondents drawn from urban areas of Lagos, Osun and Oyo states using multistage sampling technique. Descriptive statistics and Quadratic Almost Ideal Demand System were employed to analyze data collected.

The study showed sharp increase in the prices of basic foodstuffs during recession. Households were compelled to spend higher percentage of their monthly income on basic foodstuffs. Also, 51.1 percent of the respondents were government workers who experienced inconsistent or modulated monthly salary during the period. The percentage of households that were food insecure was 36.4 percent. Osun State had the highest monthly per capita expenditure (₦5,147.13) on foodstuffs, followed by Lagos and Oyo states while rice had the highest expenditure share (0.26), followed by yam (0.18), beans (0.106), vegetable oil (0.104) and garri (0.101). The breakdown also showed that 11.7, 18.1 and 17.7 percent of the total household monthly expenditures in Lagos, Osun and Oyo states, respectively, were spent on basic foodstuffs.

There purchasing power of naira reduced significantly during recession, thus compelled households to spend more on basic foodstuffs compared to similar purchases before economic recession.

The reduction in purchasing power of naira affected the formal and informal sector. Irregular salary for civil servants reduced their expenditure on goods and services.

The study is original and topical, serving as literature of accounts that transpired among the households as far as demand for basic foodstuffs is concerned during the economic recession.
