New Seeds and Women's Welfare - The Case of NERICA Upland Rice and Labor Dynamics in Hoima District, Uganda
- 2010
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- African women farmers do not always benefit from and are sometimes adversely affected by the introduction of new technologies, including high-yielding varieties and their often-associated improved management systems. This paper seeks to further this claim in the wake of what has been referred to as "the NERICA Revolution" in Uganda, by providing an illustration of the impact the introduction of NERICA upland rice has had on the gendered labor dynamics in smallholder households in Hoima District. The concrete effects on women farmers are particularly considered. To date, "the success" of the dissemination of NERICA has mainly been measured econometrically in terms of production growth or household income gain. This type of analysis allows for capturing shifts in physiological deprivations on household level. But it omits the dimension of social deprivation that, on the individual level, considers the prevalence or absence of empowering elements such as time, influence on decisionmaking, access to information and education, etc. Having researched women’s experiences of the introduction of NERICA both qualitatively and quantitatively, we conclude that while households that have adopted NERICA have, as units, become better off in economic terms (their physiological deprivation reduced), the extreme labor burden NERICA induces on women exacerbates their social deprivations, particularly in terms of time poverty and drudgery. This has policy implications. If NERICA is going to become a sustainable powerful poverty fighter in Uganda, as many hope, it is imperative that this aspect is addressed so as to avoid farmers opting out of the production over time.

- Obesity is a well-established risk factor for colorectal cancer (CRC), and accumulating evidence suggests a differential influence of sex and anthropometric factors on the molecular carcinogenesis of the disease. The aim of the present study was to investigate the relationship between height, weight, bodyfat percentage, waist- and hip circumference, waist-hip ratio (WHR), body mass index (BMI) and CRC risk according to KRAS and BRAF mutation status of the tumours, with particular reference to potential sex differences. KRAS and BRAF mutations were analysed by pyrosequencing in tumours from 494 incident CRC cases in the Malmö Diet and Cancer Study. Hazard ratios of CRC risk according to anthropometric factors and mutation status were calculated using multivariate Cox regression models. While all anthropometric measures except height were associated with an increased risk of KRAS-mutated tumours, only BMI was associated with an increased risk of KRAS wild type tumours overall. High weight, hip, waist, WHR and BMI were associated with an increased risk of BRAF wild type tumours, but none of the anthropometric factors were associated with risk of BRAF-mutated CRC, neither in the overall nor in the sex-stratified analysis. In men, several anthropometric measures were associated with both KRAS-mutated and KRAS wild type tumours. In women, only a high WHR was significantly associated with an increased risk of KRAS-mutated CRC. A significant interaction was found between sex and BMI with respect to risk of KRAS-mutated tumours. In men, all anthropometric factors except height were associated with an increased risk of BRAF wild type tumours, whereas in women, only bodyfat percentage was associated with an increased risk of BRAF wild type tumours. The results from this prospective cohort study further support an influence of sex and lifestyle factors on different pathways of colorectal carcinogenesis, defined by KRAS and BRAF mutation status of the tumours.

Tidskriftsartikel (refereegranskat)abstract
- Purpose – Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region. Design/methodology/approach – The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, together with key informant interviews with value chain participants in the three neighboring countries of Malawi, Mozambique and Zambia. Findings – In the cassava production zones, cassava's high productivity translates into per kilogram carbohydrate costs 60 per cent to 70 per cent of the cost of cereals such as maize and wheat, thereby opening up a range of profitable opportunities for commercialization of cassava-based foods, feeds and industrial products. Despite this potential, cassava commercialization in Southeastern Africa remains in its formative stages, with only 10 per cent to 30 per cent of production currently marketed. Unlike West Africa, where cassava commercialization has centered on marketing prepared cassava-based convenience foods, the emerging cassava markets in Southeastern Africa have centered on fresh cassava, low value-added cassava flour, and experiments in industrial processing of cassava-based starches, biofuels and feeds. Strategic investment in a set of key public goods (breeding, training in food sciences and food safety, and research on in-ground cassava storage) can help to shape this transition in ways that benefit both commercial interests and the food security of vulnerable households. Originality/value – The paper compares cassava commercialization across differing agro-climatic zones, policy environments and food staple zones.
