Umqombothi (a South African indigenous beer) is an important dietary beverage for many undernourished, low-income consumers in rural, semi-urban and urban areas. Umqombothi was brewed using optimal conditions earlier obtained and compared to the customary beer brew (CB) and mixed raw ingredients (RI). The products were evaluated for proximate compositions, minerals, amino acids, B-group vitamins, and sugar compounds. The optimised beer brew (OPB) was relatively higher in energy (165 kcal), crude protein (8.6%), and ash content (1.0%). The CB had the highest concentration of sodium (299.8 mg/kg), magnesium (1170.5 mg/kg), potassium (2993.8 mg/kg), and phosphorus (2100.7 mg/kg). Glutamic acid was the highest detected amino acid, with concentrations of 1.5 g/100 g, 1.5 g/100 g, and 1.6 g/100 g in the RI, CB, and OPB, respectively. The OPB contained a higher concentration of the two forms of vitamin B3, nicotinamide (0.2 µg/g) and nicotinic acid (0.7 µg/g) in comparison to the CB. The concentration of the antioxidant, mannitol, was 0.4 mg/g, 0.2 mg/g, and 2.0 mg/g in the RI, CB, and OPB respectively. Overall, OPB displayed a desirable nutritional profile compared to the CB.

This paper aims to improve understanding of the grocery retail landscape in a megacity in the developing world. Over the past ten years (i.e., 2010–2020), retail in the grocery sector in Mexico City has changed significantly. The fast growth of chain convenience stores (CCS) and the financial stability of modern channel stores (MCS) has provoked speculation about whether nanostores (i.e., mom-and-pop stores) are going to disappear or if they will endure. In developing countries nanostores dominate the grocery retail market, providing a source of income to millions of families. While some studies suggest that nanostores will keep growing in number because they are more likely to be attached to growing middle- and low-income consumers in developing countries, our results show that high- and medium–high-income consumers purchase at nanostores too. Through a comprehensive spatial statistical analysis, we provide evidence that nanostores will endure and, most importantly, coexist with MCS and CCS regardless of the socioeconomic levels that coexist in the urban areas of a developing megacity. To gain a thorough understanding of how the grocery retail market is organized in Mexico City, and provide a richer discussion on the logistics and managerial implications for stakeholders (e.g., customers, practitioners, shopkeepers, suppliers, and policymakers), we also validate hypotheses from the literature related to this context and the three channels studied in this work.

Low Income Consumers

In South Africa, studies have found changes in consumption and credit usage over time to be significant amongst low-income consumers. Yet, there has been limited empirical research on consumer behaviour in South Africa and even less on low-income consumerism. This study, which explores the relationship between materialism and indebtedness among a sample of low-income, instalment paying consumers of South Africa's largest catalogue retailer, aims to augment our understanding of these phenomena, whilst making some international comparisons.The study assesses whether (i) consumers display strong characteristics of materialism and (ii) whether materialism is a significant variable in predicting the consumers‟ propensity for incurring debt. It is concluded that low-income consumers are indeed highly materialistic. The study further suggests the presence of statistically significant relationships between consumers' levels of indebtedness and the demographic variables age and gender. However, materialism and monthly income are not significant in determining a consumer‟s level of indebtedness.While the decision to conduct the study on client data from one particular retailer, limits the extent to which the findings can be generalised to the larger South African population, the results do provide a number of important insights, which contribute to the scant body of literature on low-income consumer behaviour in the RSA.

Three cultivars ofVigna radiata, namely, NM-92, NM-98, and NM-06, were analyzed for their proximate composition. The samples were also tested by HPLC for amino acid content. The data showed that all the varieties had same moisture level. The maximum ash content (4.29%) was present in NM-92, and crude fat (2.26%) was highest in NM-98 while NM-06 contained maximum amount of crude protein. About eighteen types of amino acids were detected in each of the three varieties. Acidic amino acids, that is, aspartic and glutamic acids, were in considerable amount ranged from 13 to 23% followed by leucine, isoleucine, alanine, valine, lysine, phenyl alanine, serine, and arginine which fell in the range of 3–8% of total protein. The maximum amount (13.00 and 22.80%) of aspartic and glutamic acids was present in NM-98. Similarly arginine (6.83%) and serine (5.45%) were also in highest amount in this variety. Leucine (7.46%) was maximum in NM-92 variety. NM-06 contained almost all the amino acids in lesser quantity except for few like threonine, proline, glycine, and alanine. It was concluded from the present study that varieties were of different nutritional value and HPLC was a sensitive method for amino acids determination. Antioxidant activities of all three varieties were also assayed and showed significant results.

The Impact

At the end of 2005 and in 2006, the Western Cape suffered extended blackouts. The cuts came as a shock and customers were loud in their criticism of Eskom and the City of Cape Town’s failure to provide a reliable electricity supply. The utility Eskom’s responses included the introduction of an aggressive Demand Side Management (DSM) programme with the goal of saving electricity and reducing the need to shed customers. In Khayelitsha, Cape Town, the DSM programme entailed an exchange and subsidy programme: households were encouraged to swop their two-plate electric stoves for Liquid Petroleum Gas (LPG) stoves. This intervention is the subject of this paper. The results of the study were analysed in terms of the socio-economic characteristics of the sample interviewed, multiple fuel use and transition trends in households in urban areas, changes in behaviour in electricity and LPG use, changing perceptions of LPG and the impact of the intervention. Previous studies in household energy use showed that people perceived LPG to be dangerous saying that it posed a greater danger to the household than paraffin since it might explode. Surprisingly, during the electricity power cuts in 2006, people in low-income communities, readily accepted LPG stoves in great numbers and a year later, up to 89% of the households surveyed, reported still using LPG for cooking.

Variation in the apparent ileal digestibility of amino acids in 19 meat and bone meal samples, obtained from commercial rendering plants in New Zealand, was determined using 5-week-old broilers. Assay diets contained meat and bone meal as the only source of protein, and chromic oxide as an indigestible marker for the calculation of amino acid digestibility values. Correlations of chemical composition (crude protein, ash, crude fat, and gross energy) and in vitro assays (protein solubility in 0.2% potassium hydroxide and nitrogen digestibility by 0.2% pepsin hydrolysis) with ileal amino acid digestibility were also examined. Considerable variation was observed in the contents of crude protein (38.5–67.2 g/100 g), ash (13.0– 56.5 g/100 g), crude fat (4.3–15.3 g/ 100�g), and gross energy (9.4–22.3 MJ/kg) of meat and bone meal samples. The amino acid concentrations and ileal digestibility of amino acids also varied substantially. Cystine, the first limiting amino acid in meat and bone meal, had the lowest digestibility estimates. Correlation analyses showed that the ash content was the only chemical parameter that was consistently correlated with amino acid digestibility. Digestibility of amino acids, with the exception of aspartic acid, threonine, serine, tyrosine, histidine, and cystine, was negatively correlated with ash content, with samples with high ash levels having lower digestibility. Both in vitro assay measurements were found to be insensitive indicators of variations in amino acid digestibility.

Rural And Urban

According to Romania’s National Rural Development Programme, the socio-economic situation of the rural environment has a large number of weaknesses – among which low access to financial resources for small entrepreneurs and new business initiatives in rural areas and poorly developed entrepreneurial culture, characterized by a lack of basic managerial knowledge – but also a large number of opportunities – among which access of the rural population to lifelong learning and entrepreneurial skills development programmes and entrepreneurs’ access to financial instruments. The population in rural areas depends mainly on agricultural activities which give them subsistence living conditions. The gap between rural and urban areas is due to low income levels and employment rates, hence the need to obtain additional income for the population employed in subsistence and semi-subsistence farming, especially in the context of the depopulation trend. At the same time, the need to stimulate entrepreneurship in rural areas is high and is at a resonance with the need to increase the potential of rural communities from the perspective of landscape, culture, traditional activities and local resources. A solution could be to turn vegetal and / or animal farms into social farms – farms on which people with disabilities (but also adolescents and young people with anxiety, depression, self-harm, suicide, and alexithymia issues) might find a “foster” family, bed and meals in a natural, healthy environment, and share the farm’s activities with the farmer and the farmer’s family: “committing to a regular day / days and times for a mutually agreed period involves complying with any required health and safety practices (including use of protective clothing and equipment), engaging socially with the farm family members and other people working on and around the farm, and taking on tasks which would include working on the land, taking care of animals, or helping out with maintenance and other physical work”
