采用生态系统方法研究肯尼亚姆韦亚省疟疾与农业之间的联系。研究分为五个阶段。第一阶段有两个组成部分，包括与社区代表和其他主要利益攸关方举行的利益攸关方讲习班，以及从当地医院门诊服务记录中整理常见疾病数据。第一阶段的目的是进行先验的需求评估，以便集中研究议程。讲习班参加者直接协助选定两个有水稻灌溉的村庄和两个没有灌溉的村庄进行详细的卫生研究。在第二阶段，使用各种初步农村评估工具从研究村庄收集更详细的定性信息。定性结果表明，Mwea居民认为疟疾和缺乏清洁饮用水是他们最重要的健康问题，这一点得到了当地医院记录的证实。第三阶段包括利用第一和第二阶段的投入进行的全面住户调查。第四阶段是对有和没有水稻灌溉的那些村庄疟疾的昆虫学和寄生虫学方面进行比较评价。疟疾寄生虫学调查发现，9岁以下儿童的恶性疟原虫平均寄生率为23.5%。昆虫学评估结果显示，与没有灌溉的村庄相比，有水稻灌溉的村庄当地疟疾病媒阿拉伯按蚊的数量增加了30-300倍，但这些村庄的疟疾流行率显著降低（0-9%对17-54%）。对Mwea的“稻田悖论”最可能的解释似乎是A。在灌溉的村庄里，阿拉伯藜主要以牛为食。结果表明，尽管水稻灌溉区存在大量的疟疾，但动物预防可能是长期控制疟疾的一种可行选择。阿拉伯的。第五阶段包括项目结束讲习班，以传播研究成果和就后续行动进行参与性决策。由于采用了跨学科和参与性的研究方法，通过将旨在维持畜牧系统的农业生态系统做法纳入更广泛的农村发展战略，有可能确定在姆韦阿维持动物预防疟疾的机会。(C)2003 Elsevier B.

An ecosystem approach was applied to study the links between malaria and agriculture in Mwea Division, Kenya. The study was organized into five phases. Phase I had two components including a stakeholder workshop conducted with community representatives and other key stakeholders, and the collation of data on common diseases from outpatient service records at the local hospital. Phase I aimed at an a priori needs-assessment in order to focus the research agenda. Workshop participants directly contributed to the selection of two villages with rice irrigation and two non-irrigated villages for detailed health studies. In Phase II, various Participatory Rural Appraisal (PRA) tools were used to gather more detailed qualitative information from the study villages. The qualitative results indicated that Mwea residents considered malaria and lack of clean drinking water to be their most important health problems, and this was corroborated by local hospital records. Phase III consisted of a comprehensive household survey developed with inputs from Phases I and II. Phase IV involved a comparative evaluation of entomological and parasitological aspects of malaria in the villages with and without rice irrigation. The malaria parasitological survey found an average Plasmodium falciparum parasite rate of 23.5% among children up to 9 years of age. Results of the entomological evaluation showed a 30-300-fold increase in the number of the local malaria vector, Anopheles arabiensis, in villages with rice irrigation compared to those without irrigation yet malaria prevalence was significantly lower in these villages (0-9% versus 17-54%). The most likely explanation of this 'paddies paradox' in Mwea appeared to be the tendency for A. arabiensis in irrigated villages to feed overwhelmingly on cattle. The results suggested that zooprophylaxis was potentially a practical option for long-term malaria control in the rice irrigated areas, in spite of the large number of A. arabiensis. Phase V consisted of end-of-project workshops for the dissemination of research results and participatory decision-making regarding follow-up actions. Owing to the utilization of a transdisciplinary and participatory approach to research, it was possible to identify opportunities for maintaining zooprophylaxis for malaria in Mwea, through the integration of agroecosystem practices aimed at sustaining livestock systems within a broader strategy for rural development.
