Title: FOOD SYSTEMS THINKING UNPACKED: A SCOPING REVIEW ON INDUSTRIAL DIETS AMONG ADOLESCENTS IN GHANA Authors: Sambu, W. C.; Picchioni, F.; Stevano, S.; Codjoe, E. A.; Nkegbe, P. K.; Turner, C. Abstract: Unhealthy diets are among the main risk factors associated with non-communicable diseases (NCDs). In Sub Saharan Africa, NCDs were responsible for 37% of deaths in 2019, rising from 24% in 2000. There is an increasing emphasis on healthharming industrial foods, such as ultra-processed foods (UPFs), in driving the incidence of diet-related NCDs. However, there is a methodological gap in food systems research to adequately account for the processes and actors that shape UPFs consumption across the different domains of the food systems framework and macro-meso-micro levels of analysis. This paper interrogates how the Food Systems Framework for Improved Nutrition (HLPE in Nutrition and food systems. A report by the high level panel of experts on food security and nutrition of the committee on world food security, 2017), considered the dominant framework to analyse nutrition, and language of interdisciplinarity are practised in research with regards to consumption of UPFs among adolescents in Ghana, a population group that is often at the forefront of dramatic shifts in diets and lifestyles. We conducted a scoping review of studies published between 2010 and February 2022, retrieved 25 studies, and mapped the findings against the domains and analysis levels of the Food Systems Framework for Improved Nutrition (HLPE in Nutrition and food systems. A report by the high level panel of experts on food security and nutrition of the committee on world food security, 2017). Our study illustrates that there is a tendency to address unhealthy diets among adolescents in a siloed manner, and as a behavioural and nutritional issue. In most cases, the analyses fail to show how domains of the food systems framework are connected and do not account for linkages across different levels of analysis. Methodologically, there is a quantitative bias. From the policy point of view, there is a disconnect between national food policies and food governance (i.e., trade and regulations) and initiatives and measures specifically targeted at adolescent’s food environments and the drivers of UPFs consumption.

Title: THE IMPACT OF INSTITUTIONAL QUALITY ON LIVING STANDARDS: EVIDENCE FROM 20 SUB-SAHARA AFRICAN (SSA) COUNTRIES Authors: Suhaibu, I.; Andani, A.; Anafo, S. A. Abstract: After it has been hypothesized and empirically validated that institutional quality (InQ) is an essential ingredient for development, examining whether InQ impacts living standards (LStds) is a worthwhile exercise. Using data from 2000 to 2019 on 20 SSA countries, this study modelled the impact of InQ on LStds in a VAR framework, upon satisfactory data suitability tests. The impulse response functions and forecast error variance decomposition estimates provide evidence that InQ does not directly impact LStds but does so through its effects on financial development (FDI). As the forecast horizon moves from 1 to 5 forecast periods, InQ accounts for about 7.13% of FDI shocks, while FDI explains about 0.55% of LStd, and LStds account for about 1.13% of FDI shocks. Ultimately, InQ impacts LStds through FDI. This paper concludes that FDI optimizes inflation and improves LStds, while inflation retards FDI in the short-run. The autocorrelation LM and Eigen value tests confirmed the robustness of the results. Government in SSA should implement laws and policies that will strengthen institutions to improve the LStds of their people.

Title: SOCIAL NETWORKS, ADOPTION OF IMPROVED VARIETY AND HOUSEHOLD WELFARE: EVIDENCE FROM GHANA Authors: Abdul Mumin, Y.; Abdulai, A. Abstract: In this study, we examine the effects of own and peer adoption of improved soybean variety on household yields and food and nutrient consumption, using observational data from Ghana. We employ the marginal treatment effect approach to account for treatment effect heterogeneity across households and a number of identification strategies to capture social network effects. Our empirical results show that households with higher unobserved gains are more likely to adopt because of their worse outcomes when not adopting. We also find strong peer adoption effect on own yield, only when the household is also adopting, and on food and nutrient consumption when not adopting. However, the peer adoption effect on consumption attenuates when the household adopts the improved variety. Furthermore, our findings reveal that adoption tends to equalise households in terms of observed and unobserved gains on consumption and can thus serve as a mechanism for promoting food security and nutrition in this area.

Title: NONFARM ACTIVITY AND MARKET PARTICIPATION BY FARMERS IN GHANA Authors: Nkegbe, P.K.; Araar, A.; Abu, B.M.; Alhassan, H.; Ustarz, Y.; Setsoafia, E.D.; Abdul‑Wahab, S. Abstract: This paper examines the relationship between participation in nonfarm activity and participation in markets by farm households in Ghana. The study used data from the Ghana Living Standards Survey Round 6 and employed the endogenous switching probit model which accounts for selection bias from observed and unobserved fac tors. The results reveal that infrastructural variables such as roads, means of transport, markets and banks are important determinants of nonfarm work engagement and par ticipation in crop market. We also fnd a positive and signifcant efect of nonfarm work participation on the probability of selling crops. The conclusion is that farmers’ engage ment in nonfarm activities boosts decisions to enter crop markets in Ghana. The results of the study imply that for agricultural development in Ghana and other countries with similar characteristics, agricultural policies should incorporate strategies that enhance opportunities in the nonfarm sector as that will translate to enhanced producer market participation.
