    This study assessed microbial contamination of water in sources (boreholes and open wells) and selected households in four Malawian villages (situated in Bangwe Township, Blantyre city) by analyzing the presence of faecal coliforms using membrane filtration. Additionally, pH, conductivity and temperature of the water sources were also determined. Conductivity ranged from 150.5 to 1575 μS/cm. About 70% of all water sources were above World Health Organization (WHO) and Malawi Bureau of Standards (MBS) limits for conductivity (indicating salty water in the area). Water temperature ranged from 21.5 to 24.7°C and pH from 5.28 to 6.95 with no significant difference (p > 0.05) for these physical parameters among the sampling points. Water pH was within MBS range while 60% of water sources were below WHO range. Faecal coliform levels exceeding WHO and MBS safe standards were observed in 79% of all samples analysed in this study. Mean household faecal coliform levels were as follows (village (mean)); Nalivata (437 CFU/100 mL), Mpingwe 1 (172 CFU/100 mL), Mpingwe (266 CFU/100 mL) and Salvation Army (15 CFU/100 mL). All mean faecal coliform counts were above WHO (0  CFU/100 mL) and MBS (0 CFU/100 mL) safe values. The results suggest that the quality of water in the villages often fails to meet one or more WHO and MBS recommended safe levels as such, poses a potential risk to the health of those individuals living in such villages. Local and National Governments should therefore target the provision of safe water to such populations. The findings of this study also highlight the need for improved dissemination of good hygienic practices amongst such communities.Key words: Boreholes, drinking water, faecal coliforms, health, pollution

    Economic framework for integrating environmental stewardship into food security strategies in low-income countries: case of agroforestry in southern African region

    Get PDF
    One of the greatest challenges in many Sub-Saharan Africa countries especially where seasonal food deficits occur frequently, is how best to achieve a balance between the goals of food security and agricultural production on the one hand, and the concerns for the conservation of environmental quality and natural resources capital on the other. A number of agricultural production technologies (based on natural resource management principles) exist that offer opportunities for achieving the two seemingly divergent goals because they have the characteristics to produce joint multiple outputs, i.e, they produce food and provide environmental services. However, farmer adoption of these technologies has generally been limited. Drawing from natural resource economics, this study presents a conceptual framework that provide environmental-economic logic for establishing incentives that internalize the environmental services produced by multiple-outputs land use technologies. Using a land use practice based on agroforestry principles (that is, “improved tree fallows”) as a case study, this paper synthesizes studies carried out in southern Africa region for over a decade. It then discusses how the potential impacts of the technological advances made in research and development are affected by policy and institutional constraints, among other challenges. With particular emphasis on the socio-economic context in southern Africa, the paper identifies options for addressing these institutional and policy constraints in order to facilitate adoption of multi-output land use practices by farmers and unlock their potential to meet food production goals for individual households and environmental services for the wider society.Keywords: Adoption, Agri-Environmental quality, Environmental services, Natural resource economics, Payment for environmental services, Science-policy linkage

    Soil organic matter is at the nexus of global challenges: food security, climate change adaptation and mitigation, soil security. The 4 per 1000 initiative, launched at the Climate COP21 within the Lima-Paris Action Agenda proposes to increase soil organic carbon (SOC) stocks to simultaneously address all these challenges. It directly addresses three sustainable development goals: SDG2 ?no hunger?, SDG13 ?Climate action?, and SDG15 ?Life on land? and indirectly concerns several others. The initiative targets agricultural soils in priority, which are often the most degraded soils and because of the high expected benefits in terms of soil fertility and hence of productivity. A range of agricultural practices are available that allow to increase SOC stocks while ensuring a resilient, productive and environmentally friendly agriculture, so that a large-scale deployment can be aimed at. Here, we review and discuss the main limits and criticisms addressed to the 4 per 1000 initiative

    Psychosocial issues and coping mechanisms of pregnant and postnatal women diagnosed with COVID-19: A qualitative study

    Objective There is a paucity of data on the psychosocial issues and coping mechanisms among pregnant and postnatal women with COVID-19 infection. We, therefore, aimed to explore the psychosocial issues and coping mechanisms of pregnant and postnatal women diagnosed with COVID-19 at tertiary-level hospitals. Methods This was a qualitative phenomenological study conducted in 2021 with a sample size of 16 women admitted at two referral hospitals serving as COVID-19 admission facilities for pregnant and postnatal women in Lusaka, Zambia. In-depth interviews were conducted via telephone to understand what these women experienced when diagnosed with COVID-19. All the interviews were audio-recorded and transcribed verbatim. Thematic analysis was conducted using the six steps approach to develop emerging themes. Results Two major themes emerged: psychosocial issues and coping mechanisms. The primary psychosocial issues were worry and stigma. Women worried about infecting their unborn baby or neonate, being separated from the baby, the general safety of the baby, and the health of other family members. Women also worried about the attitude of health care providers and faced discrimination or stigma because of their infection. Thus, some coping mechanisms were developed that helped them, such as a positive attitude, keeping the disease secret, reliance on family members for support and using positive information from social media. Conclusion This study provides unique insights into the psychosocial experiences of pregnant and postnatal women diagnosed with COVID-19. Women were particularly concerned about the unborn baby's well-being and discrimination.This study suggests the need for policy and clinical practice to consider the integration of effective mental health services into the provision of maternal health and COVID-19 services

    Age at sexual debut is known to have implications for future sexual behaviours and health outcomes, including HIV infection, early pregnancy and maternal mortality, but may also influence educational outcomes. Longitudinal data on schooling and sexual behaviour from a demographic surveillance site in Karonga district, northern Malawi, were analysed for 3153 respondents between the ages of 12 and 25 years to examine the association between sexual debut and primary school dropout, and the role of prior school performance. Time to dropout was modelled using the Fine and Gray survival model to account for the competing event of primary school completion. To deal with the time-varying nature of age at sexual debut and school performance, models were fitted using landmark analyses. Sexual debut was found to be associated with a five-fold increase in rate of subsequent dropout for girls and a two-fold increase in dropout rate for boys (adjusted hazard ratio [aHR] of 5.27, CI 4.22-6.57, and 2.19, CI 1.77-2.7, respectively). For girls who were sexually active by age 16, only 16% ultimately completed primary schooling, compared with 70% aged 18 or older at sexual debut. Prior to sexual debut, girls had primary completion levels similar to those of boys. The association between sexual debut and school dropout could not be explained by prior poor school performance: the effect of sexual debut on dropout was as strong among those who were not behind in school as among those who were overage for their school grade. Girls who were sexually active were more likely to repeat a grade, with no effect being seen for boys. Pathways to dropout are complex and may differ for boys and girls. Interventions are needed to improve school progression so children complete primary school before sexual debut, and to improve sex education and contraception provision

    Improving validity of informed consent for biomedical research in Zambia using a laboratory exposure intervention.

    BACKGROUND: Complex biomedical research can lead to disquiet in communities with limited exposure to scientific discussions, leading to rumours or to high drop-out rates. We set out to test an intervention designed to address apprehensions commonly encountered in a community where literacy is uncommon, and where complex biomedical research has been conducted for over a decade. We aimed to determine if it could improve the validity of consent. METHODS: Data were collected using focus group discussions, key informant interviews and observations. We designed an intervention that exposed participants to a detailed demonstration of laboratory processes. Each group was interviewed twice in a day, before and after exposure to the intervention in order to assess changes in their views. RESULTS: Factors that motivated people to participate in invasive biomedical research included a desire to stay healthy because of the screening during the recruitment process, regular advice from doctors, free medical services, and trust in the researchers. Inhibiting factors were limited knowledge about samples taken from their bodies during endoscopic procedures, the impact of endoscopy on the function of internal organs, and concerns about the use of biomedical samples. The belief that blood can be used for Satanic practices also created insecurities about drawing of blood samples. Further inhibiting factors included a fear of being labelled as HIV positive if known to consult heath workers repeatedly, and gender inequality. Concerns about the use and storage of blood and tissue samples were overcome by a laboratory exposure intervention. CONCLUSION: Selecting a group of members from target community and engaging them in a laboratory exposure intervention could be a useful tool for enhancing specific aspects of consent for biomedical research. Further work is needed to determine the extent to which improved understanding permeates beyond the immediate group participating in the intervention

    Climate variation based on temperature and solar radiation data over a 29 year period in Lilongwe City, Malawi

    Economies that mainly depend on agriculture are to a large extent being negatively impacted by climate change. In this study, temperature and solar radiation data from Chitedze Weather Station, Lilongwe City, Malawi for a 29-year period (1985 to 2013) were assessed for the possibility of climate variation. In addition, the concentration of carbon dioxide over Malawi within the same period as temperature and solar radiation data was assessed for inferences. The highest mean minimum temperature (15.7°C) was recorded in 2010. The highest mean maximum temperature (27.9°C) and solar radiation (21.5 MJm-2day-1) were recorded in 2005. The mean minimum temperature showed an increasing pattern but both mean maximum temperature and solar radiation data showed a lot of variation. There were significant differences (p < 0.05) among mean minimum and maximum temperature and solar radiation. The carbon dioxide concentration over Malawi has been increasing over the years which is one of the contributors to rising mean minimum temperatures.Key words: Climate variation, solar radiation, temperature, weather
