Abstract

Human labor requirements for rice production practices in the developing world are assessed in terms of baseline worker hours and energy costs per hectare. Modifications of traditional cultivation systems are analyzed with respect to agricultural techniques (the methods by which inputs are powered) and technologies (the applications of knowledge to the production system) used. Human labor, animal labor and mechanical sources of energy are compared within traditional, improved and modern modes of technology. Nine different technique/technology options are examined in terms of energy efficiency for land preparation and seeding, harvesting and threshing, as well as auxilliary intercultivation procedures. Specific employment planning strategies are suggested, based on the results of the operational analysis.

在发展中国家,人类劳动力作为水稻生产的能源
发展中国家水稻生产实践的人力需求是根据每公顷的基准工时和能源成本来评估的。对传统耕作系统的修改进行了分析,涉及所使用的农业技术(为投入提供动力的方法)和技术(将知识应用于生产系统)。人类劳动、动物劳动和机械能源在传统、改进和现代技术模式下进行了比较。在土地准备和播种、收获和脱粒以及辅助的互耕程序的能源效率方面,审查了九种不同的技术/技术选择。根据业务分析的结果,提出了具体的就业规划策略。
