《Food Policy》2019
Innovations within global food systems have contributed to the predicament known as the triple burden of malnutrition – the co-existence of hunger and micronutrient deficiency with the diseases of overnutrition, such as obesity, diabetes and hypertension. We use the case of the triple burden in South Asia to demonstrate analytically that innovation is a double-edged sword, with positive and negative potential, rather than a simple good. To achieve the Sustainable Development Goals that target food and nutrition security and sustainable agriculture (e.g. SDGs 2, 3 and 12), the countries of South Asia need more innovation, but, first, they would also benefit from some intelligent reflection about what innovation means, the directions it should take, and its risks and downsides alongside its benefits. In the present juncture, South Asian countries have an opportunity to learn from the experiences of other developing nations, and choose from alternative options to steer their own course. In this paper, we discuss how innovation has contributed to the present situation and ask how alternative kinds of innovation may enable South Asian countries to escape from the triple burden. We describe a conceptual framework that may be useful for thinking about how innovation pathways can be created and directed towards the goal of improving nutritional outcomes in South Asia. The framework draws attention to the direction of socio-technical change, the distribution of technologies and their risks and benefits, and the diversity of possible innovation pathways (STEPS Centre, 2010). We illustrate these points using examples of innovations in the areas of agricultural production, value chain interventions, and policy and institutional reforms. 相似文献

In an attempt to provide a technological solution to the influx of cheap imports in South Africa and bridging the technology divide between Africa and the rest of the world, the Council for Scientific and Industrial Research procured a three‐dimensional body scanner from the Textile and Clothing Technology Corporation, in the US. The pilot study was aimed at introducing the technology to the South African consumers, and to compare the scanned data with the manually taken measurements. A convenience sample of 56 females in South Africa was interviewed using a structured questionnaire. Interviews were used to capture views on acceptance of the technology, prior to being scanned. Scanning garments made from a stretchy fabric were designed and sewn in four sizes of small, medium, large and extra large. A covariance, one sample t‐test and paired t‐ tests were used for data analyses. Almost all respondents felt comfortable with the designed scanning garments and the scanning process. The scanner measurements were generally more numerical in value than the manual measurements for a body part as expected, although the disparity was on the higher side than expected. The discernible difference between means of scanned data and standard values in the currently used sizing charts highlighted the long overdue need to update the sizing charts using a national anthropometric database generated locally. 相似文献

从亚洲各国资产证券化的发展来看,无论是发行数量还是发行品种,日本、韩国都分列前两位.根据日本资产证券化发展过程中标的资产种类多样、产品设计复杂化和韩国资产证券化过程中政府强有力的信用支持和法制推进作用这些特点,得出日韩资产证券化快速发展的原因主要是政府的大力支持、国际投行的积极参与和其在资产证券化方面拥有高水平人才.我国从日韩资产证券化的发展中得到的启示是:要快速发展资产证券化市场,建立和完善相关法律法规,加强证券化标的资产的市场建设,积极学习外国先进经验,培养相关学科知识密集型人才. 相似文献

In contrast to rapid economic growth in the twentieth century, Korea suffered a long economic decline in the eighteenth and nineteenth centuries, with the failure accelerating from 1850 to 1890. According to 36 different harvest records, rice productivity continuously declined from the early eighteenth to the late nineteenth centuries due to deforestation and increase in natural disasters. Contraction of rural markets after the interruption of trade with Japan also contributed to the decrease in rice production. The third reason for the nineteenth‐century crisis was the dissolution of the government‐led grain storage and redistribution system. Finally, the ultimate culprit for the crisis could be found in Confucianism with which the Joseon Dynasty was unable to properly understand and respond to the crisis. 相似文献
