- Previous studies in drylands have shown that while gender roles are becoming more flexible, privatization and formalization of land tenure tends to marginalize women in drylands while environmental degradation leads to differential changes in gender workload. Chepareria, a ward in West Pokot County, has undergone the above-mentioned tenure and environmental changes and is nowadays dominated by private enclosures as a land management approach. This study reviewed in which ways these rangeland enclosures have influenced gender roles in the dryland systems of Chepareria in West Pokot, with specific regard to division of labour, financial responsibilities and decision-making processes on the household level, and also tries to identify the underlying driving forces that have contributed to the observed changes.Our results indicate that the workload of women has increased under new land fragmentation processes in rangelands due to increased responsibilities in cattle herding and income generation, but also that due to this, women have gained higher influence in household decisions concerning the family economy. It was found that women to a larger extent than before are engaged in small-scale business such as the selling of farm products and poultry keeping, hence getting financial resources under their own control. In this way, women are involved in decision-making processes and income generation to a higher extent than before, though they are still excluded from certain traditionally male-dominated spheres both within and beyond the household, such as the sale of cattle and the handling of larger amounts of financial resources.Under the new land fragmentation processes in Chepareria, women are increasingly seen as crucial income earners and they are enjoying a higher degree of financial independence, more decision-making power and a louder voice than before in household and public matters.

Tidskriftsartikel (refereegranskat)abstract
- Vitamin A deficiency is common among preschoolers in low-income settings and a serious public health concern due to its association to increased morbidity and mortality. The limited consumption of vitamin A-rich food is contributing to the problem. Many factors may influence children's diet, including residential food environment, household wealth, and maternal education. However, very few studies in low-income settings have examined the relationship of these factors to children's diet together. This study aimed to assess the importance of residential food availability of three plant-based groups of vitamin A-rich foods, household wealth, and maternal education for preschoolers' consumption of plant-based vitamin A-rich foods in Addis Ababa. A multistage sampling procedure was used to enroll 5467 households with under-five children and 233 residential food environments with 2568 vendors. Data were analyzed using a multilevel binary logistic regression model. Overall, 36% (95% CI: 34.26, 36.95) of the study children reportedly consumed at least one plant-based vitamin A-rich food group in the 24-h dietary recall period. The odds of consuming any plant-based vitamin A-rich food were significantly higher among children whose mothers had a higher education level (AOR: 2.55; 95% CI: 2.01, 3.25), those living in the highest wealth quintile households (AOR: 2.37; 95% CI: 1.92, 2.93), and in residentials where vitamin A-rich fruits were available (AOR: 1.20; 95% CI: 1.02, 1.41). Further research in residential food environment is necessary to understand the purchasing habits, affordability, and desirability of plant-based vitamin A-rich foods to widen strategic options to improve its consumption among preschoolers in low-income and low-education communities.

Significant association and synergistic adverse prognostic effect of podocalyxin-like protein and epidermal growth factor receptor expression in colorectal cancer
- 2016
-

Tidskriftsartikel (refereegranskat)abstract
- Background: Podocalyxin-like 1 (PODXL) is an anti-adhesive transmembrane protein that has been demonstrated to be an independent factor of poor prognosis in colorectal cancer (CRC). The gene encoding PODXL is located to chromosome 7, which also harbours the gene for the epidermal growth factor receptor (EGFR). The aim of this study was to examine the associations between PODXL and EGFR expression in CRC in vitro and in vivo. Methods: EGFR expression was analysed in tumours from three independent patient cohorts; cohort 1 (n = 533), cohort 2 (n = 259) and cohort 3 (n = 310), previously analysed for immunohistochemical PODXL expression and KRAS and BRAF mutations (cohort 1 and 3). Levels of EGFR and PODXL were determined by western blot in six different CRC cell lines. Results: High expression of PODXL was significantly associated with high EGFR expression (p < 0.001) in all three cohorts, and with BRAF mutation (p < 0.001) in cohort 1 and 3. High EGFR expression correlated with BRAF mutation (p < 0.001) in cohort 1. High EGFR expression was associated with adverse clinicopathological factors and independently predicted a reduced 5-year overall survival (OS) in cohort 1 (HR 1.77; 95 % CI 1.27-2.46), cohort 2 (HR 1.58; 95 % CI 1.05-2.38) and cohort 3 (HR 1.83; 95 % CI 1.19-2.81). The highest risk of death within 5 years was observed in patients with tumours displaying high expression of both EGFR and PODXL in cohort 1 and 3 (HR 1.97; 95 % CI 1.18-3.28 and HR 3.56; 95 % CI 1.75-7.22, respectively). Western blot analysis showed a uniform expression of PODXL and EGFR in all six examined CRC cell lines. Conclusions: The results from this study demonstrate that high expression of EGFR is an independent factor of poor prognosis in CRC. Moreover, strong links have been uncovered between expression of the recently proposed biomarker candidate PODXL with EGFR expression in CRC in vivo and in vitro, and with BRAF mutation in vivo. High expression of both PODXL and EGFR may also have a synergistic adverse effect on survival. These findings suggest a potential functional link in CRC between PODXL, EGFR and BRAF, all originating from chromosome 7, which may be highly relevant in the clinical setting and therefore merit future in-depth study.

Bokkapitel (refereegranskat)abstract
- 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.

Food, farming and health in Ugandan secondary cities
- 2019
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This research contributes to countering a large city research bias by focusing on the food, farming and health experiences of two secondary cities of Uganda: Mbale and Mbarara. It is not an apocalyptic story. Like anywhere in the world, for some residents things were going well; for others, less well. My research explores the varied geometries of advantage and disadvantage in diets, food security, and livelihood circumstances to shed light on why things were more secure for some than for others. I used multiple methods including a household survey, focus groups with local healthcare professionals, and in-depth interviews with varied city residents. A geographic perspective explored intersections of food, farming and health with aspects of identity (such as gender, class, tribe), and with place (the city itself, but also with rural areas, or other urban areas). The starting point was the theorised food system, nutritional and epidemiologic transitions predicted to occur with urban development, often called nutrition transition theory. My research suggests caution with dominant models of how urban life shifts food and farming systems towards a food system and diet pattern focused around large retailer supermarkets, processed foods, fast foods, more meat, less agriculture, less movement. Nutrition transition theory postulates these changes causing a shift in epidemiology from infectious to non-infectious diseases in urban areas. Instead of the suggestion from nutrition transition theory, my work presents evidence of non-communicable disease (obesity, diabetes, hypertension) experience in Mbale and Mbarara’s residents, but without evidence of advanced change in food and farming systems. Findings revealed relatively low dietary diversities and common food insecurity. Diets remained predominantly traditional, as did the main food sources (traditional markets and neighbourhood shops), across diverse residents. The more food secure had regular salaried employment and strong relational links with rural farms and family, supporting work on multi-spatial livelihoods. This contrasts with earlier ideas of who farms the African city, or retains farming livelihoods. Most vulnerable to food insecurity and low diet diversity were those who were most dependent on purchasing all their food. In conclusion, this research suggests that food system, nutritional and epidemiologic transitions in Mbale and Mbarara may be less linked than previously thought, or linked in more complex ways. Other drivers of epidemiologic change are likely. Findings highlight the importance of local data and specific city investigations.

Non-Farm Activities and Impacts beyond the Economy of Rural Households in Vietnam: A Review and Link to Policies

Tidskriftsartikel (refereegranskat)abstract
- Rural households in Asian developing countries such as Vietnam have been participating in non-farm activities for decades, yet impacts beyond the economy of these households are little understood. Using evidence from available literature and two case studies from rural Vietnam, this paper exposes a range of socio-cultural impacts of non-farm activities. An increased social tension driven by a widening economic gap between poor and better-off households or ethnic majority and minority groups was the most frequently reported impact in the literature. The case studies reveal additional impacts, notably those associated with public security, preservation of local culture, and safety of farm households with migrants during and following climate-related disasters. An increasing number of young migrants who exited family farms to access non-farm jobs partially led to the latter two impacts. The rural development and poverty reduction policies of Vietnam enacted in the past two decades (2000–2020) that promoted livelihood diversification had limited measures addressing socio-cultural impacts of non-farm activities. An amendment of these two categoriesof policies for the implementation beyond 2020 or a strengthened synergy in implementation with other categories of policy such as social policies is necessary to ensure sustainable rural development in Vietnam.

Building pastoralists’ resilience to shocks for sustainable disaster risk mitigation: Lessons from West Pokot County, Kenya
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Most pastoralists’ in Sub Saharan Africa (SSA) are adversely affected by climate-change related shocks such as droughts and livestock diseases. These shocks lead to deterioration of livestock quality and even mass death of herds. This leaves pastoralists vulnerable as they derive most of their food and income needs from livestock, necessitating emergency disaster response and the need to build their long-term adaptive capacity. In most cases however, investments only focus on reducing risks and not on building long-term adaptation strategies. In this study, we analyzed factors affecting household resilience among the pastoralists of West Pokot County in Kenya. A focus group discussion and key informant consultations were held to understand community perspectives on the historical nature of climate-change related shocks. In additional, individual household surveys were done with 191 randomly selected households to obtain information on the shocks experienced by pastoralists, coping strategies, long term adaptation strategies and external support, their uptake of these and the effect on their resilience. The household resilience index was constructed using Principal Component Analysis (PCA). An ordered probit regression was used to analyze the effect of socio-demographic, institutional factors and adaptive practices on households’ resilience. It was noted that years of formal schooling, household income, access to credit and extension and adaptive practices such as post harvest use of field crops for grazing, enclosures, stocking improved breeds, bee keeping, ethno-veterinary practices and afforestation have a positive and significant effect in building household resilience to shocks. There is therefore a need to direct investment to bolster pastoralists’ own efforts towards building their resilience.
