Assessment of awareness of mycotoxins infections in stored maize (Zea mays L.) and groundnut (arachis hypogea L.) in Kilosa District, Tanzania
(2016) Magembe, K. S.; Mwatawala, M. W.; Mamiro, D. P.; Chingonikaya, E. E.
Background: Surveys were conducted to determine awareness of mould infection in maize and groundnut in Kilosa District, Eastern Central Tanzania, between August and October 2010. Four villages of Msingisi, Rudewa-Batini, Mamoyo and Mkalama were surveyed. We sampled maize from each household for mycotoxins contamination after nine months of storage. A questionnaire was administered to heads of 72 selected households in the study area. Principal component analysis (PCA) was used to check factor dimensionality. The differences in mean total score of knowledge and awareness between the demographic and socio-economic factors were determined by t-test. Measurements of association were carried by Chi-square test (χ2), while ordinal logistic regression analysis was used to examine the correlations between social variables and awareness of mould infection. Results: We found high levels of fumonisins in maize that ranged from 70.46 to 213.15. Aflatoxin levels in groundnuts ranged from 72.97 to 195.17. Result showed that 97 % of respondents were not aware of mould infection in stored maize and groundnuts. The mean score of mould infections awareness of females (1.7273±0. 45055) was significantly higher than that of males (1.5714±13.7). Awareness of mould infection was high among educated (mean score 1.9231.3±0.31470) than the less educated people (mean score 1.8913±0.27175). Results revealed significant association between awareness of mould infection with age (p=0.006), education (p=0.039), marital status (p=0.012), gender (0.037) and income (p=0.044). Conclusion: Campaigns are needed to improve awareness of mould infection in Kilosa District, Tanzania.
Fuelwood consumption in brick making: A case of Morogoro Municipality, Tanzania
(2015-11) Magembe, K. S.; Makonda, F. B. S.; Masanja, M. M
The study aimed at determination of the annual fuel wood consumption caused by brick making activities in Morogoro municipality, Tanzania. The collected and analyzed data were based on field survey and quantitative measurements. Field survey based on interviews with group leaders dealing with brick making activities as the main focus was conducted. Data were collected from brick maker’s survey as well as from some relevant secondary sources. The study revealed that almost all brick makers in the municipal used fuelwood as the major energy sources. The average annual fuelwood consumption for brick making was 8,610 m3. In order to reduce heavy dependency of fuelwood in the area, use of alternative energy sources in brick making such as rice husks, maize cobs and baggasse are recommended. The study also recommends the establishment of woodlots in all wards, establishment of agro-forestry systems and intensive afforestation and reforestation programmes to be undertaken by the municipality for more sustainable fuelwood use.
