Book (stand-alone)Technical book玉米田草地贪夜蛾 综合防治
非洲农民田间学校指南
2020Also available in:
草地贪夜蛾(Spodoptera frugiperda)是一种原产于美洲的危险跨境害虫，自2016年起迅速传入非洲所有区域，给作物造成巨大损害。农民教育和社区行动是采用综合生态害虫管理方法防治草地贪夜蛾种群最有效管理战略的关键要素。农民田间学校(FFS)是一个已经在90多个国家使用的综合农民教育方法，将成为应对草地贪夜蛾防治工作的重要手段。 本指南旨在就如何在非洲草地贪夜蛾综合及可持续管理方面开展农民田间学校工作进行指导，并以玉米围绕草地贪夜蛾为重点。本指南介绍草地贪夜蛾生物学和生态学，以及为期一季的农民田间学校采取的田间试验和练习，并针对如何为草地贪夜蛾农村咨询服务/推广而设计培训计划，和农民田间学校骨干培训师和辅导员的进修课程提出了建议。 -
Book (series)FlagshipThe State of Food and Agriculture 2019
Moving forward on food loss and waste reduction
2019The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability. -
