As one element of agricultural service delivery, in Ethiopia crop protection service has generally only involved the private sector on a small scale. This article outlines a case study where private crop protection service (PCPS) was strengthened from 2006 to 2010 in Halaba Special District, southern Ethiopia. The study used questionnaires, analysis, service comparison, ranking, and indicator-based assessments. The study shows that PCPS in 2007/08 crop seasons served 1,104 households on 1,707?ha of land in 19 Kebeles, contributing US$327,752 in total. Assessment indicators values were better for PCPS than the informal crop protection service. Piloting PCPS strengthening is recommended to improve crop protection service and reduce crop loss in Ethiopia. 相似文献

Feedback in foreign policy occurs when a state's foreign policy affects the international context of that state and those changes in context subsequently impact on the state's future foreign policy decisions. In this way, feedback loops can develop, which may become self-reinforcing and in which foreign policy and international context continuously affect each other. Even though such processes are ubiquitous especially in a globalized world, they have hitherto received little systematic attention. We introduce cybernetics as a perspective that puts such feedback effects at the centre of attention and provides an accessible sequential framework for analysing them. Such a cybernetic analysis not only demonstrates the significance of feedback processes in foreign policies but also speaks to several recent debates in international relations theory and foreign policy analysis. In particular, it highlights processes of learning and change, of non-linearity and indeterminacy, and enables the researcher to integrate insights from structure- and agency-based approaches. We outline the merits of a cybernetic analysis by discussing the effects of feedback in the United States' War on Terror. 相似文献
