Unfortunately, bush beans are severely affected by frequent water-logging which persists over a considerable period of the year. In spite of this, farmers have continued to cultivate bush bean though with miserable yields. The study aimed to identify farmers' indigenous coping mechanisms to the climatic predicament, as a foundation for nurturing and subsequently designing appropriate management strategies for improved bean production in the region. A household survey was conducted in Kisoro district, in a location representative of the ecological conditions of Uganda-Rwanda region. 96 respondents were selected randomly at village level from a list of 500 households provided by the extension workers. Data were collected using semi-structured interviews. Findings showed that farmers possess vital coping mechanisms including construction of ridges, fertiliser application and chemical control of pests and diseases to expedite plant growth, and construction of drainage channels. It is clear that farmers' indigenous coping mechanisms need further nurturing and refining to improve their performance in dealing with water-logging crisis in the region.展开更多

In-depth interviews carried out with 68 respondents from 2009 to 2013, in six selected Teso districts in Uganda and Teso and Busia districts in Kenya, before and after performances, provided the data. In placing value and assessing the unquantifiable feelings of narrators and audiences, the study chose the methods of qualitative research and ethno-methodological philosophical analyses. Various levels of perceptions emerged from both the audiences and performers as they journeyed into both self and society. The study showed that the communities yearned for the communicative avenues of harnessing resources for solving various issues as they look into the future. Oral narratives motivated audiences through experiences of self discovery which spurred them to analogies of societal issues that haunted them. Both value and virtue were experienced at individual and group levels with a cultural identity and exposure to ethnic ties that bound them together in the struggle for a brighter tomorrow. The study recommends that a new society can be realized with movement from analogue to digital strategies for communication.展开更多

China is a country with multiple ethnic minorities, which have extremely rich ethnic minority dresses and adornment elements. On studying the major dress adornment elements of the Daur, a typical ethnic minority in northern China, we have discovered their strong ethnic features. The major dress adornment elements of the Daur were with the purpose to explore and continue traditions. Combining the modern faskion design with the delicate decorative art that the Daur people sew various laces and embroideries on their dresses, was to discover and use the essence of Chinese ethnic dress and adornments, and demonstrate the talent of ethnic minorities in clothes design. Given what have been founded, combined with the application of modern design methods, the adornment elements of ethnic dresses can represent their ethnic characteristics as well as reflecting the sense of the modern age.展开更多
