In Africa and South Asia, where nutrition insecurity is severe, two of the most prominent production technologies are genetically modified (GM) crops and certified organic agriculture. We analyze the potential impact pathways from agricultural production to nutrition. Our review of data and the literature reveals increasing farm-level income from cash crop production as the main pathway by which organic agriculture and GM agriculture improve nutrition. Potential secondary pathways include reduced prices of important food crops like maize due to GM maize production and increased food production using organic technology. Potential tertiary pathways are improvements in health due to reduced insecticide use. Challenges to the technologies achieving their impact include the politics of GM agriculture and the certification costs of organic agriculture. Given the importance of agricultural production in addressing nutrition security, accentuated by the post-2015 sustainable development agenda, the chapter concludes by stressing the importance of private and public sector research in improving the productivity and adoption of both GM and organic crops. In addition, the chapter reminds readers that increased farm income and productivity require complementary investments in health, education, food access and women's empowerment to actually improve nutrition security.
在营养不安全状况严重的非洲和南亚,两种最突出的生产技术是转基因作物和经认证的有机农业。我们分析了从农业生产到营养的潜在影响途径。我们对数据和文献的审查表明,经济作物生产带来的农场收入增加是有机农业和转基因农业改善营养的主要途径。潜在的次要途径包括,转基因玉米生产导致重要粮食作物如玉米价格下降,以及使用有机技术增加粮食产量。潜在的第三途径是因减少杀虫剂使用而带来的健康改善。这些技术实现其影响面临的挑战包括转基因农业的政治问题和有机农业的认证成本。鉴于农业生产在解决营养安全方面的重要性,2015年后可持续发展议程进一步凸显了这一点,本章最后强调了私营和公共部门研究对于提高转基因作物和有机作物的生产力及采用率的重要性。此外,本章提醒读者,农场收入和生产力的提高需要在健康、教育、粮食获取和妇女赋权方面进行补充投资,以切实改善营养安全。
