This study investigates the relationship between climate variables such as rainfall amount, temperature, and carbon dioxide (CO2) emission and the triple dimension of food security (availability, accessibility, and utilization) in a panel of 25 sub-Saharan African countries from 1985 to 2018. After testing for cross-sectional dependence, unit root and cointegration, the study estimated the pool mean group (PMG) panel autoregressive distributed lag (ARDL). The empirical outcome revealed that rainfall had a significantly positive effect on food availability, accessibility, and utilization in the long run. In contrast, temperature was harmful to food availability and accessibility and had no impact on food utilization. Lastly, CO2 emission positively impacted food availability and accessibility but did not affect food utilization. The study took a step further by integrating some additional variables and performed the panel fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) regression to ensure the robustness of the preceding PMG results. The control variables yielded meaningful results in most cases, so did the FMOLS and DOLS regression. The Granger causality test was conducted to determine the causal link, if any, among the variables. There was evidence of a short-run causal relationship between food availability and CO2 emission. Food accessibility exhibited a causal association with temperature, whereas food utilization was strongly connected with temperature. CO2 emission was linked to rainfall. Lastly, a bidirectional causal link was found between rainfall and temperature. Recommendations to the national, sub-regional, and regional policymakers are addressed and discussed.

Orientation: The article examines the impact of mobile money adoption and regional financial integration in sub-Saharan Africa.Research purpose: The study sought to uncover the relationship between mobile money adoption and cross-border remittances as a de facto measure of regional integration.Motivation for the study: The extent to which differences in mobile money penetration rates across sub-Saharan Africa influence cross-border remittances remains a grey area that necessitates empirical investigation.Research approach, design and method: A quantitative research method was adopted and the study examined aggregated quarterly data obtained from 41 countries making up the four regions of sub-Saharan Africa. The study applied the dynamic ordinary least squares and fully modified ordinary least squares approaches as the estimation techniques.Main findings: Mobile money adoption has positively impacted cross-border remittances and improved de facto regional financial links in sub-Saharan Africa. The study’s findings also support the view that better governance through control of corruption and political stability removes dependence on remittances.Practical/managerial implications: There is a need to integrate mobile money and other cross-border remittance platforms to improve access to financial services for migrants and harness their savings into the mainstream economy.Contributions/value-add: The study adds to the body of knowledge by showing that higher mobile money penetration rates have regional integration benefits.

This paper sets out to investigate the effects of agricultural expenditures on two dimensions of food security in Sub Saharan Africa from 2000-2016. The Feasible Generalized Least Square (FGLS) econometric technique was applied on data from World Development Indicator, Regional Strategic Alliance and Knowledge Support System (ReSAKSS), the World Governing Indicator, the African Development Indicators, the Food and Agricultural Organisation (FAO) data bases. Our results depicted that public agricultural expenditure has negative and significant effects on food availability and utilization while domestic private agricultural expenditure and human capital foster both dimensions of food security. Foreign aid for agriculture has no effects on food availability but promotes food utilization while economic infrastructure promotes food availability but the effects on food utilization are positive and not significant. On the basis of the results, we recommend that SSA African government should increase the size of public agricultural expenditure, increase the level of economic infrastructures so as to crowd in private agricultural investment, lobby for more foreign aid for agriculture, improve the quality of institutions and design different policies to target different dimensions of food security.

Many solutions have been proposed to address food security. We present here a prioritized set of actions achievable within the next 2–10 years. By taking a systems approach we follow the impact pathway backwards starting from the needs and desires of the end-users to eventually define the research agenda that will exactly address those targeted solutions with positive impacts. The following actions emerge as high-priority and achievable in the near future: new research tools to study food systems; dis-aggregated intra-household surveys to reveal within-family inequalities in food access; increased scientific consensus on climate change impacts in sub-Saharan Africa; rapid response measures to address sudden emergencies, such as capturing excess rainfall water; financial tools to enable rapid responses with recovery measures afterwards; consideration of restrictions that excess heat and humidity impose on human productivity; secure land ownership and tenure rights to encourage long-term agricultural investment; mechanization at all stages along the food system.

The amount of remittances to developing counties, defined as the flow of monetary and non-monetary goods, has increased globally and has surpassed the amount of money spent on foreign aid in these developing countries. The impact of remittances on households’ purchasing power has been studied; however, its link to food security status is yet to be explored. This paper quantitatively analyses the relationship between food security status (measured using the Food Insecurity Experience Scale) and the receipt of domestic/ international or both remittances on households in sub- Saharan Africa. Data are derived from the Gallup World Poll from the years 2014-2017. Multinomial logistic regression models and binary logistic regression analyses were conducted to analyze the data. Results showed that remittance recipients had significantly higher household incomes (especially if the remittance was coming internationally and domestically), lived with significantly more household members (7 or more members), and were more likely to be separated (including divorced or widowed). Households that received domestic remittances had significantly higher odds of being food insecure than households receiving no remittances. Conversely, households receiving remittances internationally or a combination of domestic and international remittances had significantly lower odds of food insecurity compared to non-receivers. This study found that receiving remittances affect the food security status of people living in SSA countries.

Abstract The sub-Saharan Africa region has been affected by multifaceted interrelated challenges including climate change risks, environmental degradation, political crises, demographic, and food security. The region is geographically exposed to and heavily depends on heat stress-sensitive livelihood and economy. Unlike drought, flood, and erratic rainfall, the situation and impact of heat stress are not well documented. This paper summarized the impact of heat stress on various sectors of the Sahel region. The result revealed that exposure to heat stress contributed to water, agricultural, food security, health, and economic adverse impacts in sub-Saharan Africa. The study also shows in sub- Saharan Africa especially in semiarid and arid areas the future impact of heat stress in various sectors is expected to be more severe. The changes and impacts of heat stress are not uniform across the region. For instance, East Africa is at higher risk of acquiring concurrent health impacts. West Africa is projected to experience severe impacts on food production. South Africa observes the strongest decrease in precipitation with concurrent risks of drought. Thus, understanding the effect of heat stress on humans and various heat-sensitive sectors should be the focus of researchers. However, given the degree of uncertainty of the models' results and effect of heat stress in the region, it is important to develop adaptive capacities at different ecological settings that enable the region population to adapt to risk factors related to climate change and heat stress.

Purpose Although several factors influence property value determination depending on the market, relevant studies in sub-Saharan Africa (SSA) often fail to analyse the impact of factors, such as unexpired term of leasehold interest and ground rent, which are also germane to market transactions and value determination. This study aims to examine the effect of unexpired term of leasehold interests and ground rent on the valuation of residential properties in Ghana. Design/methodology/approach A questionnaire instrument was used to collect the views of a sample of professional real estate valuers on the relevance of these and other factors that affect value. In addition, the valuers were tasked to value a residential property located in Accra, Ghana. Ordinary least squares and quantile regression models were thereafter used to analyse the data to determine the effect of the subject variables on value. Findings The study finds a significant relationship between valuers’ views on the relevance of unexpired term of leasehold interest and the value placed on residential properties. Further, the respondents who viewed ground rent as an important factor in estimating values placed significantly lower values than those who viewed it as less important. Research limitations/implications The findings suggest that the respondents may have split opinion on the existing anecdotal evidence that market participants ignore the unexpired term of leasehold interest, an issue that should be settled in theory. The findings also highlight the diversity of opinion on some of the fundamental factors that affect value and the need to build consensus to prevent excessive variation in value estimates among valuers. Originality/value The study makes a significant contribution in terms of extending the existing literature by analysing the impact of unexpired term of leasehold interests and ground rent on residential property values based on empirical data, issue(s) which have often been ignored by existing studies. Findings from the study also provide insights into additional possible causes of valuation errors in Ghana and SSA, which are useful for policy formulation and practice.

We calculated a simple indicator of food availability using data from 93 sites in 17 countries across contrasted agroecologies in sub-Saharan Africa (>13,000 farm households) and analyzed the drivers of variations in food availability. Crop production was the major source of energy, contributing 60% of food availability. The off-farm income contribution to food availability ranged from 12% for households without enough food available (18% of the total sample) to 27% for the 58% of households with sufficient food available. Using only three explanatory variables (household size, number of livestock, and land area), we were able to predict correctly the agricultural determined status of food availability for 72% of the households, but the relationships were strongly influenced by the degree of market access. Our analyses suggest that targeting poverty through improving market access and off-farm opportunities is a better strategy to increase food security than focusing on agricultural production and closing yield gaps. This calls for multisectoral policy harmonization, incentives, and diversification of employment sources rather than a singular focus on agricultural development. Recognizing and understanding diversity among smallholder farm households in sub-Saharan Africa is key for the design of policies that aim to improve food security.

AbstractBackgroundMany low- and middle-income countries have implemented control measures against coronavirus disease 2019 (COVID-19). However, it is not clear to what extent these measures explain the low numbers of recorded COVID-19 cases and deaths in Africa. One of the main aims of control measures is to reduce respiratory pathogen transmission through direct contact with others. In this study we collect contact data from residents of informal settlements around Nairobi, Kenya to assess if control measures have changed contact patterns, and estimate the impact of changes on the basic reproduction number (R0).MethodsWe conducted a social contact survey with 213 residents of five informal settlements around Nairobi in early May 2020, four weeks after the Kenyan government introduced enhanced physical distancing measures and a curfew between 7pm and 5am. Respondents were asked to report all direct physical and non-physical contacts made the previous day, alongside a questionnaire asking about the social and economic impact of COVID-19 and control measures. We examined contact patterns by demographic factors, including socioeconomic status. We described the impact of COVID-19 and control measures on income and food security. We compared contact patterns during control measures to patterns from non-pandemic periods to estimate the change in R0.FindingsWe estimate that control measures reduced physical and non-physical contacts, reducing the R0 from around 2.6 to between 0.5 and 0.7, depending on the pre-COVID-19 comparison matrix used. Masks were worn by at least one person in 92% of contacts. Respondents in the poorest socioeconomic quintile reported 1.5 times more contacts than those in the richest. 86% of respondents reported a total or partial loss of income due to COVID-19, and 74% reported eating less or skipping meals due to having too little money for food.InterpretationCOVID-19 control measures have had a large impact on direct contacts and therefore transmission, but have also caused considerable economic and food insecurity. Reductions in R0 are consistent with the linear epidemic growth in Kenya and other sub-Saharan African countries that implemented similar, early control measures. However, negative and inequitable impacts on economic and food security may mean control measures are not sustainable in the longer term.Research in contextEvidence before this studyWe conducted a PubMed search on 6 June 2020 with no language restrictions for studies published since inception, using the search terms (“social mix*” OR “social cont*” OR “contact pattern*) AND (“covid*”). The search yielded 53 articles, two of which reported changes in social contacts after COVID-19 control measures. The first study reported changes in contact patterns in Wuhan and Shanghai, and the second changes in contact patterns in the UK. We found no studies examining changes in contact patterns due to control measures in sub-Saharan Africa, and no studies disaggregating contacts by socioeconomic status.Added value of this studyThis is the first study to estimate the reproduction number of COVID-19 under control measures in sub-Saharan Africa using primary contact data. This study also moves beyond existing work to i) measure contacts in densely populated informal settlements, ii) explore how social contacts vary across socioeconomic status, and iii) assess the impact of control measures on economic and food security in these areas.Implications of all the evidenceCOVID-19 control measures have substantially reduced social contacts and disease transmission. People of lower socioeconomic status face greater transmission risk as they report more contacts. Control measures have led to considerable economic and food insecurity, and may not be sustainable in the long term without efforts to reduce the burden of control measures on households.
