生物多样性公约(CBD)将生物多样性定义为“从所有来源包括生物体之间的可变性,尤其,陆地、海洋和其他水生生态系统和生态复合体的一部分;这包括物种多样性、物种之间和生态系统。“换句话说,它是各种各级地球上的生命,从基因到全球人口相同的物种。不同层次的生物多样性包括含有丰富的生物多样性,生态系统物种和物种和社区不同的基因型,这包括农业生物多样性。所有组件的农业生物多样性相关食品和农业,支持农业生态系统发生(粮农组织、2008)是很重要的。因此,饮食多样性变得重要,因为保护生态系统的一种手段。饮食多样性可以定义为不同的食物或食物组消耗的数量在给定参考时期,通常1 – 2周。饮食多样性已经被证明可以改善营养状况(康德等,2000;Kiokia和黄金,2004;吉布森等,2000)。因此,它也可以帮助打击隐性饥饿,因此双重负担。饮食多样性是反映家庭粮食安全,因为描绘了可访问性、可用性的食物和在某种程度上稳定。Hoddinott和遗址上分析的证据来自10个国家饮食多样性家庭访问链接的热量和延伸食品安全(2002)。

The Convention on Biological Diversity (CBD) defines biodiversity as “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.” In other words, it is the variety of life on earth at all levels, from genes to worldwide populations of the same species. The different Levels of biodiversity include ecosystem containing rich biodiversity, species and communities of species and different genotypes, and this includes agricultural biodiversity. All components of agricultural biodiversity relevant to food and agriculture and support the ecosystem that agriculture occurs is important (FAO, 2008). Thus, dietary diversity becomes important as a means of protecting the ecosystem.Dietary diversity can be defined as the number of different foods or food groups consumed over a given reference period, usually 1-2 week. Dietary diversity has been shown to improve nutritional status (Kant et al, 2000; Kiokia and Golden, 2004; Gibson et al, 2000). Thus, it also can aid in combating hidden hunger, and thus double burden. Dietary diversity is a reflection of household food security because depicts accessibility, availability of foods and to some extent stability. Hoddinott and Yohannes analysis of evidence from 10 countries links dietary diversity to household access of calorie and by extension food security (2002).
