African farm trajectories and the sub-continental food crisis

This is a study of farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals mainly with food crops and in detail with maize and makes a longitudinal analysis by systematically comparing current conditions with those obtaining when the farm was set up under its present management. From the study emerges an overall picture of inadequately exploited production potentials where farmers’ commercial energies are driven towards other food crops than grains, especially vegetables for urban markets. Commercial incentives in food grain production favour small groups of well-placed and usually male farmers, while, the lack of seed-fertiliser technology and commercial incentives means that smallholders devote their energies to other crops or to non-farm sources of income

Drills and Diets, Consumption and Conservation– the Role of Primate Meat in Local Diets in and Around Cross River National Park, Nigeria

The study uses household level data from four villages inand around Cross River National Park (CRNP), Nigeria to assess therole of primate meat in local livelihoods and diets. Okwangwo is anenclave community within the national park, Butatong houses theCRNP headquarters. Kanyang1 and Abo Ebam are located fartheraway from the park. 149 respondents were surveyed. Sale ofbushmeat contributed 4 percent of total cash income on average, butis important as a source of protein in the context of poorly developedlivestock systems. 98 percent of the households ate bushmeat duringthe past year and 74 percent hunted for consumption. 77 percent atemeat from primates, although this varied from 53 percent in Butatongto 97 percent in Okwangwo. Differences emerge among the villageswith less reliance on bushmeat, less hunting and a dietary shifttowards poultry in Butatong. There is no correlation between incomelevels and consumption of primate meat. The overwhelming motivefor eating primate meat was taste preferences. Solutions tounsustainable extraction of primate meat must be sourced in relationto local consumption. Improving access to animal source foods,through widening the livestock basis of local agraria

Analysing diet composition and food insecurity by socio-economic status in secondary African cities

This chapter takes as its starting point theorizing around nutrition and food system transitions thought to be increasingly occurring in urban Africa, and how this may be linked to a growing non-communicable disease burden. We focus specifically on the secondary city context by analysing household survey data gathered from six cities across Ghana, Kenya and Uganda during 2013–2015. We asked how diet composition and diversity, food sources and food security varied by socio-economic status, using expenditure and demographic data to create a proxy for household well-being. In this way, we investigate one of the claimed keystones affecting urban food systems and dietary health in sub-Saharan Africa—that of obesogenic urban food environments. Our findings indicate that the socio-economic status of a household was the most important factor influencing household dietary diversity and food security status, i.e. better-off households were more likely to feel food secure and eat from a greater variety of food groups. In addition, the number of income sources was additionally associated with higher dietary diversity. We also found that a household’s involvement in agriculture had only a small positive effect on food security in one city and was associated with a reduction in dietary diversity scores. Our findings emphasize the importance of supporting aggregated national and international statistics on agricultural production and trade with detailed local analyses that focus on actual household food access and consumption. We also see reasons to be cautious about making causal claims regarding consumption change and obesogenic urban environments as the major contributor to a rising obesity and non-communicable disease burden in Africa

Mixed blessings: a qualitative exploration of mothers’ experience of child care and feeding in the rapidly urbanizing city of Addis Ababa, Ethiopia

Many studies have drawn attention to the vital role mothers have in safeguarding the health and nutritional wellbeing of their children. However, little is known about mothers’ experiences and the challenges they face in fulfilling this role in rapidly urbanizing cities in Africa. This study aims to explore child care and feeding practices of mothers with children under five years of age in Addis Ababa, Ethiopia. This qualitative study was conducted using a semi-structured interview guide. A total of thirty-six interviews were conducted with purposively selected participants. All interviews were audio recorded, transcribed verbatim and translated for analysis. We used a thematic analysis approach, which was guided by a resilience framework. The findings are presented as three major themes. 1) ‘Mixed blessings-balancing motherhood’s expectations’. While mothers identified positively with the social recognition and sense of fulfillment of being a ‘good mother’, they were ambivalent/torn about earning the necessary income from outside work and fulfilling their duties at home. 2) ‘Instabilities due to rampant urban sprawl’. While women expressed a keen desire to balance work and motherhood, the disintegrating social capital, due to large in-migration, market fluctuations and abrupt/forced resettlements to new housing units had left mothers without support for childcare, stressed and exhausted. 3) ‘Anchored by faith: a source of resilience to cope with adversities’. In the face of the multiple adversities, mothers cited their strong faith as their most reliable foundation for their resilience. In summary, the societal and environmental changes accompanying the rapid urbanization in low income settings makes combining child care and working outside the home very challenging for mothers. As a result they suffer from fatigue and feelings of isolation. Efforts to improve child feeding and care in urban low-income settings need to consider context appropriate strategies that support mothers with small children

Sex differences in the prognostic significance of KRAS codons 12 and 13, and BRAF mutations in colorectal cancer: a cohort study

Background: Activating KRAS and BRAF mutations predict unresponsiveness to EGFR-targeting therapies in colorectal cancer (CRC), but their prognostic value needs further validation. In this study, we investigated the impact of KRAS codons 12 and 13, and BRAF mutations on survival from CRC, overall and stratified by sex, in a large prospective cohort study. Methods: KRAS codons 12 and 13, and BRAF mutations were analysed by pyrosequencing of tumours from 525 and 524 incident CRC cases in The Malmö Diet and Cancer Study. Associations with cancer-specific survival (CSS) were explored by Cox proportional hazards regression, unadjusted and adjusted for age, TNM stage, differentiation grade, vascular invasion and microsatellite instability (MSI) status. Results: KRAS and BRAF mutations were mutually exclusive. KRAS mutations were found in 191/ 525 (36.4%) cases, 82.2% of these mutations were in codon 12, 17.3% were in codon 13, and 0.5% cases had mutations in both codons. BRAF mutations were found in 78/524 (14.9%) cases. Overall, mutation in KRAS codon 13, but not codon 12, was associated with a significantly reduced CSS in unadjusted, but not in adjusted analysis, and BRAF mutation did not significantly affect survival. However, in microsatellite stable (MSS), but not in MSI tumours, an adverse prognostic impact of BRAF mutation was observed in unadjusted, but not in adjusted analysis. While KRAS mutation status was not significantly associated with sex, BRAF mutations were more common in women. BRAF mutation was not prognostic in women; but in men, BRAF mutation was associated with a significantly reduced CSS in overall adjusted analysis (HR = 3.50; 95% CI = 1.41–8.70), but not in unadjusted analysis. In men with MSS tumours, BRAF mutation was an independent factor of poor prognosis (HR = 4.91; 95% CI = 1.99–12.12). KRAS codon 13 mutation was associated with a significantly reduced CSS in women, but not in men in unadjusted, but not in adjusted analysis. Conclusions: Results from this cohort study demonstrate sex-related differences in the prognostic value of BRAF mutations in colorectal cancer, being particularly evident in men. These findings are novel and merit further validation

Social Stratification, Diet Diversity and Malnutrition among Preschoolers: A Survey of Addis Ababa, Ethiopia

In Sub-Saharan Africa, being overweight in childhood is rapidly rising while stunting is still remaining at unacceptable levels. A key contributor to this double burden of malnutrition is dietary changes associated with nutrition transition. Although the importance of socio-economic drivers is known, there is limited knowledge about their stratification and relative importance to diet and to different forms of malnutrition. The aim of this study was to assess diet diversity and malnutrition in preschoolers and evaluate the relative importance of socioeconomic resources. Households with children under five (5467) were enrolled using a multi-stage sampling procedure. Standardized tools and procedures were used to collect data on diet, anthropometry and socio-economic factors. Multivariable analysis with cluster adjustment was performed. The prevalence of stunting was 19.6% (18.5–20.6), wasting 3.2% (2.8–3.7), and overweight/obesity 11.4% (10.6–12.2). Stunting, overweight, wasting and limited diet diversity was present in all social strata. Low maternal education was associated with an increased risk of stunting (Adjusted odds ratio (AOR): 1.8; 1.4–2.2), limited diet diversity (AOR: 0.33; 0.26–0.42) and reduced odds of being overweight (AOR: 0.61; 0.44–0.84). Preschoolers in Addis Ababa have limited quality diets and suffer from both under- and over-nutrition. Maternal education was an important explanatory factor for stunting and being overweight. Interventions that promote diet quality for the undernourished whilst also addressing the burgeoning problem of being overweight are needed

What influences urban mothers’ decisions on what to feed their children aged under five—the case of addis ababa, Ethiopia

Mothers carry the prime responsibility for childcare and feeding in low-income countries. Understanding their experiences in providing food for their children is paramount to informing efforts to improve the nutritional status of children. Such information is lacking in Sub-Saharan Africa. To understand what influences urban mothers’ food acquisition and their motivations for selecting food for their children, 36 in-depth interviews were carried out with mothers having children under five years of age. Interviews were conducted in the local language, audio-recorded, transcribed, and translated into English. Data were analyzed using thematic analysis which led to the identification of four major themes: mothers give-in to a child-driven diet; quick-fix versus the privilege of planning; keen awareness on food safety, nutrition, and diet diversity; and social, familial, and cultural influences. The findings indicate that child feeding practices are influenced by interlinked social and environmental factors. Hence, nutrition education campaigns should focus on targeting not only families but also their children. Attention should also be given to food safety regulations, as well as to the much-needed support of mothers who are struggling to ensure their children’s survival in low-income countries

DISTRIBUCIÓN DE LAS ÁREAS VERDES, ÍNDICE DE MARGINACIÓN Y JUSTICIA AMBIENTAL EN LEÓN, GUANAJUATO

Las áreas verdes constituyen un elemento estratégico para la sostenibilidad de las ciudades, ya que poseen cualidades que derivan en la mejora de la calidad de vida y el bienestar social. No obstante, la ciudad de León, Guanajuato, muestra una distribución desigual y deficitaria en la dotación de áreas verdes, lo cual se manifiesta en una exclusión socio-espacial de los beneficios que estos espacios brindan a toda la población. El trabajo evidencia que las zonas con menor índice de áreas verdes coinciden con las zonas de mayor índice de marginación, especialmente en el caso de los siete polígonos de pobreza de ciudad. El reto que subyace para la ciudad es lograr una distribución justa y equitativa de las áreas verdes, mediante instrumentos de planificación que permitan lograr la sostenibilidad urbana, con justicia ambiental y correlacionarse positivamente con los índices de marginación
