How justified is the complaint sometimes voiced by British businessmen and other UK visitors to contemporary Africa that, compared to 'the [good old] colonial days', Britain's FCO representatives have no experience of Africa and little idea about who's who and what's going on in their bailiwick? The aim of this article is to construct a professional profile of Britain's Heads of Mission assigned to newly independent African states over the past 35 years, with a view to assessing the extent of their African experience. This period also neatly coincides with what in one sense can be interpreted as a single FO generation, in that the mean entry age into the Diplomatic Service is around 25 and the maximum retiring age is a strict 60. The statistical biodata on which the argument is premised are presented in the 19 Mission Tables appended. The article concludes with an examination of the major issues surrounding the question of 'African experience' among those Heads of Mission. 相似文献

While rural poverty is endemic in the Andean region, structural adjustment programmes have led to a dismemberment of agricultural research and extension services so that they are unable to serve the needs of smallholder farmers. The NGO Practical Action has been working in the Andes to address farmers' veterinary and agriculture needs. The work has included the training of farmer-to-farmer extension agents, known locally as Kamayoq. The Kamayoq have encouraged farmer participatory research, and local farmers pay them for their veterinary and crop advisory services in cash or in kind. The Kamayoq model is largely an unsubsidised approach to the provision of appropriate technical services and encouragement of farmer participation. The model also illustrates that, in the context of encouraging farmer participation and innovation, NGOs have advantages over research organisations because of their long-term presence, ability to establish trust with local farmers, and their emphasis on social and community processes. 相似文献

Participatory research approaches are increasingly popular with scientists working for poverty alleviation, sustainable rural development, and social change. This introduction offers an overview of the special issue of Development in Practice on the theme of ‘operationalising participatory research and gender analysis’. The purpose of this special issue is to add value to the discussion of methodological, practical, philosophical, political, and institutional issues involved in using gender-sensitive participatory methods. Drawing on 16 articles, we place some of the main issues, empirical experiences, and debates in participatory research and participatory technology development in the context of implementation, evaluation, and institutionalisation of participatory research and evaluation approaches. 相似文献
