“…The number of foods reported as part of habitual diets varied considerably. The highest reported values include 76 fish and other animal species (Begossi and Richerson 1993), 32 and 62 vegetables species (Ogle et al 2001b;Steyn et al 2001), 26 and 40 fruit species (Nordeide et al 1996;Passos et al 2007), and between 21 and 51 varieties of rice (Frei and Becker 2004;Kennedy et al 2005). The studies also reported a wide interval of consumption frequencies for some foods, going from several times per day to a different number of times per year, and some indicated seasonal variations (data not shown).…”

“…Studies investigating the contribution of biodiversity to dietary diversification reported mainly the number of food items within the diet (Begossi and Richerson 1993;Nordeide et al 1996;Osemeobo 2001;Steyn et al 2001;Frei and Becker 2004;Kennedy et al 2005;Pieroni et al 2005;Nebel et al 2006;Batal and Hunter 2007;Dovie et al 2007;Passos et al 2007;Rais et al 2009).

“…Only a few of these studies used a quantified dietary intake assessment (Rajasekaran and Whiteford 1993;Mennen and Mbanya 2000;Kuhnlein et al 2004Kuhnlein et al , 2006Roche et al 2008). Other studies (Begossi and Richerson 1993;Ogle et al 2001a;Steyn et al 2001;Lykke et al 2002;Kennedy et al 2005;Batal and Hunter 2007;Akrofi et al 2008) used a combination of local food biodiversity and dietary assessments, exploring thereby the intake of local foods and naming the species involved.…”

The sustainable use of natural and agricultural biodiversity in the diet can be instrumental to preserve existing food biodiversity, address malnutrition, and mitigate adverse effects of dietary changes worldwide. This systematic review of literature summarizes the current evidence on the contribution of plant and animal biodiversity to human diets in terms of energy intake, micronutrient intake, and dietary diversification. Peer-reviewed studies were searched in ten databases using pre-defined search terms. Only original studies assessing food biodiversity and dietary intake were included, resulting in a total of 34 studies. 7, 14, and 17 studies reported information in relation to energy intake, micronutrient intake, and dietary diversification, respectively. In general, locally available foods were found to be important sources of energy, micronutrients, and dietary diversification in the diet of particularly rural and forest communities of highly biodiverse ecosystems. The current evidence shows local food biodiversity as important contributor of nutritious diets. Findings are, however, limited to populations living in highly biodiverse areas. Research on the contribution of biodiversity in diets of industrialized and urban settings needs more attention. Instruments are needed that would more appropriately measure the dietary contribution of local biodiversity.

The narrowing of diversity in crop species contributing to the world's food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of crop species in national food supplies worldwide. Over this period, national per capita food supplies expanded in total quantities of food calories, protein, fat, and weight, with increased proportions of those quantities sourcing from energy-dense foods. At the same time the number of measured crop commodities contributing to national food supplies increased, the relative contribution of these commodities within these supplies became more even, and the dominance of the most significant commodities decreased. As a consequence, national food supplies worldwide became more similar in composition, correlated particularly with an increased supply of a number of globally important cereal and oil crops, and a decline of other cereal, oil, and starchy root species. The increase in homogeneity worldwide portends the establishment of a global standard food supply, which is relatively species-rich in regard to measured crops at the national level, but species-poor globally. These changes in food supplies heighten interdependence among countries in regard to availability and access to these food sources and the genetic resources supporting their production, and give further urgency to nutrition development priorities aimed at bolstering food security.A shared axiom of ecology and nutrition is that, within certain ranges, diversity enhances the health and function of complex biological systems. Species diversity has been shown to stimulate productivity, stability, ecosystem services, and resilience in natural (1-5) and in agricultural ecosystems (6-13). Likewise, variation in food species contributing to diet has been associated with nutritional adequacy (14-17) and food security (18).The development of sedentary agricultural societies and further rise of modern agriculture is generally considered to have led to a decline in the total number of plant species upon which humans depend for food (19,20), particularly the wild, semidomesticated, and cultivated vegetables and fruits, spices, and other food plants that supplemented staple crops with the provision of micronutrients and that bolstered food security historically during crop failures (21). Harlan (20) warned that most of the food for mankind comes from a small number of crops and the total number is decreasing steadily. In the United States in the past 40 years, many vegetables and fruits have disappeared from the diet, and the trend is going on all over the world. More and more people will be fed by fewer and fewer crops.More recent analyses of dietary transition in developing countries in association with globalization have noted increases in the diversity of plants contributing to diets locally, along with a Westernization transition in preference of energy-dense foods (i.e.,...

“…While food production has obviously increased overall, some have raised concerns that the world's reliance on a smaller number of food crops may make global food security more susceptible to local interruptions in production (Alston et al 2009;Ray et al 2013). Moreover, for at least some populations, a shift from traditional to Western diets has decreased their nutritional intake (Graham et al 2007;Kennedy et al 2005;Ruel 2003).…”

Genomic breeding for food, environment and livelihoods

Land use management is a central challenge for the 21st century with unprecedented and competing demands to produce food, feed/fodder, fibre, fuel, and essential ecosystem services which sustain life. Global change requires rapid adaptation in current and emerging crops as well as in the foundation species of natural ecosystems. Revolutions in genomics and high throughput experimentation are transforming breeding so that adaptive traits in new environments can be predicted and selected more directly from germplasm collections of crops and wild species. This genomic breeding is now feasible in almost any species and has promise to help meet the need to feed and nourish over 9 billion people by 2050. Genomic techniques can accelerate our response to food security challenges of yield, quality and resilience and also address environmental security challenges. To achieve its potential there will need to be widespread and ongoing investments in the human capital to promote genomic breeding.
