Even in the 21st century, undernutrition is a challenge to be overcome. In the year 2009, 1.02 billion people were reported as food insecure and 180 million children were undernourished. Food insecurity and undernutrition are more than a lack of food energy: they are not reflected countrywide by prevalence means; they are mostly not permanent but seasonal; they are mostly not caused by insufficient amounts of food being produced; and they first affect parents and later children. Food insecurity and undernutrition often manifest themselves as micronutrient deficiency. While undernutrition is still a challenge for global nutrition, a second challenge has arisen: preventing caloric overnutrition. In various countries, food pyramids or food circles have been plotted supporting nutrition education and illustrating the challenge. Such integrative approaches are desirable for all countries of the world, as in all countries, to a smaller or larger extent, undernutrition and caloric overnutrition are the problems of today and tomorrow. The International Assessment of Agriculture for Science Technology and Development (IAASTD) has paid attention to the inescapable interconnectedness of agriculture's different roles and functions in the world and in all societies. Overcoming undernutrition with local resources means first protecting and promoting the use of local resources against imports of low-priced processed foods from subsidised production in industrialised countries; second, it means developing education and training material for regional food production with a nutrition orientation; and third, the experiences of organic farming can contribute much to support farmers in developing countries in planting their indigenous varieties and applying integrated pest management strategies.
即使在 21 世纪,营养不良仍是一个亟待解决的挑战。2009 年,据报道有 10.2 亿人面临粮食无保障,1.8 亿儿童营养不良。粮食无保障和营养不良不仅仅是缺乏食物能量:它们不能用患病率来反映全国范围的情况;它们大多不是永久性的,而是季节性的;它们大多不是由生产的食物数量不足引起的;而且它们首先影响父母,然后影响孩子。粮食无保障和营养不良往往表现为微量营养素缺乏。虽然营养不良仍然是全球营养的一个挑战,但第二个挑战已经出现:预防热量营养过剩。在不同的国家,已经绘制了食物金字塔或食物圈,以支持营养教育并说明这一挑战。这种综合方法是全世界所有国家都需要的,因为在所有国家,无论程度大小,营养不良和热量营养过剩都是当今和未来的问题。国际农业科学技术评估组织(IAASTD)关注农业在世界和所有社会中的不同角色和功能不可避免的相互联系。利用当地资源克服营养不良意味着首先要保护和促进当地资源的利用,以抵御来自工业化国家补贴生产的低价加工食品的进口;其次,这意味着要开发具有营养导向的区域性粮食生产教育和培训材料;第三,有机农业的经验可以为发展中国家的农民提供很大的支持,帮助他们种植本地品种并应用综合虫害管理策略。
