Transcript of Mainstream agriculture vs wild and underutilized species for nutrition
Mainstreamed agriculture versus wild and underutilized species and
varieties for nutrition
U. Ruth Charrondiere, PhD
FAO, Rome
Global nutrition situation • Double burden of malnutrition
Undernutrition and micronutrient deficiencies are persisting. Obesity is endemic also in developing countries.
• Increased consumption of animal
products (e.g. China and India) and of processed foods.
• Simplification of diets and shift
towards westernized diets.
• Medicalized approach (fortification and supplementation) instead of a food-based approach using foods.
Astronauts’ diets
NASA (America)
• Foods only
• no supplements except for vitamin D
Is this achievable on earth?
Biodiversity and Nutrition What is biodiversity?
1. inter-species biodiversity (in nutrition called diverse diets) i.e. eat many different foods
2. Intra-species biodiversity (in nutrition called biodiversity) is adding a new dimension below species level
– varieties, cultivars and breeds
– but also wild, neglected and underutilized species (NUS)
differences in nutrient content between species are as high as within species (up to 1000 times)
difference between nutritional adequacy and inadequacy

Consumer information
Vitamin A deficiency in Micronesia • Traditionally, vitamin A deficiency was not know
• With shift to westernized diets (e.g. white rice and mutton tails) vitamin A deficiencies arrived
• Nutrition programme developed based on green leafy vegetables did not work as considered ‘pig foods’
• Exploration of traditional diets showed that local varieties of bananas and taro were very rich in carotenoides –> current programme re-introduces the traditional diet seems to work. See http://www.islandfood.org
The Great Vitamin A Fiasco (M. Latham)
• “Vitamin A (capsule) programmes are ineffective. They use up precious human and material resources. Most of all, they impede other approaches to the prevention of vitamin A deficiency [...]. These include breastfeeding, and the protection and development of healthy, affordable and appropriate food systems and supplies. Such approaches also protect against other diseases, are sustainable, enhance well-being, and have social, cultural, economic and environmental benefits.”
• “capsules do not have a significant effect on mortality” but de-worming and measles vaccination are effective
• “exceedingly rich sources of carotene such as palm and other fruits, tend to be overlooked [...], one reason being that they often grow wild, and even when cultivated do not feature in international or national food composition tables ”
Why consider biodiverse foods/NUS? • May have very interesting food compositions –
however often not known because not analyzed
• Part of local food systems: food culture, taste, traditions, medicine and spirituality
• Sustainable:
– Survived for centuries
– Contribute to resilient ecosystem
– Needed for adaptation to climate change and external shocks
– Represent the genetic resources to improve mainstreamed crops and breeds
Why are NUS ‘forgotten’? Agriculture emphasize on 3 crops (wheat, corn, maize) and the big 5 (cattle, pigs, chickens, sheep and goats) for research, production, subsidies, marketing and food security. And on energy only. Therefore:
• NUS have poor economic competitiveness because of little or no investments in NUS
• NUS lower productivity, yield, income and marketing
• NUS could be more labour intensive
• NUS got/will get lost if not used
• Changes towards more Western style diets and lifestyles
• Stigma of “food of the poor”.
Links between biodiversity, food and nutrition recognized by:
• International Rice Commission (2002)
• Convention on Biological Diversity (CBD) – in 2014 links to health added and WHO
• Commission on genetic resources for food and agriculture (CGRFA)
• FAO
• ICN2 (2014)
Links increasingly recognized by more organizations and bodies and with a wider scope
How to achieve food security Objective: to produce sufficient nutrients for a healthy diet for all at all times and ensure that a population is able to acquire foods in sufficient quantity and quality and to utilize them efficiently.
Availability • Agricultural production = foods for
humans • Not only quantity (yield and
energy) is important but quality (esp. micronutrient content) = shift in paradigm
• Processed foods should contain good nutrient profiles
Access • Market, income
Utilization • Human body is in good health • Foods and water are safe • Consumers demand high quality foods • Adequate intra-household distribution of
foods
Stability • Economic, political, environmental and
GR stability • Sustainable agriculture conserving and
utilizing biodiversity • Sustainable consumption
Factors influencing nutrient composition of rice
Rice varieties
Source: adapted from T. Longvah, NIN, India
Environmental conditions: water, light
Fertilizer Soil
quality Milling Cooking Storage
Agricultural influence Post harvest influences
Genetics
International Rice Commission The Commission recommended that:
• Existing biodiversity of rice varieties and their nutritional composition need to be explored before engaging in transgenic research.
• Nutrient content needs to be among the criteria in cultivar promotion.
• Cultivar-specific nutrient analysis and data dissemination should be systematically undertaken.

Optimal food with
•high nutrient content
•high yield and pest resistance
•high acceptance by population
•acceptable price

Commission on Genetic Resources for Food and Agriculture (CGRFA) endorsed in 2015
Voluntary Guidelines for Mainstreaming Biodiversity into Policies, Programmes and National and Regional Plans of Action on Nutrition:
• Rational – why the guidelines are important
• Objectives – assist countries in mainstreaming GF
• Principles – including element for planning
• Three main elements
– Research – describe knowledge gap and way forward
– Implementation – describe important components
– Awareness – describe how to raise awareness of the general public and of the different stakeholders

GEF-funded project Mainstreaming Biodiversity
Conservation and Sustainable Use for Improved Human
Nutrition and Well-being (2012 – 2017)
Objectives:
- Conservation of biodiversity through use
- Improve supply and demand side:
Through increased scientific evidence (food
composition) identify foods high in nutrients.
Increase their market potential and public awareness
- Influence policies to integrate biodiversity
BFN project: New analytical data to be generated on their composition
• Sri Lanka: 6 plant species (20 varieties)
• Brazil: 70 underutilized fruit species + 20 traditional vegetable species
• Kenya: 12 plant and animal species
• Turkey: 43 wild plant species
Challenges when mainstreaming NUS Example quinoa - International year of quinoa in 2013
• Global demand increased for ‘standardized’ products
• New products and market chains developed
• Price increased in Bolivia
– More income for farmers
– Poor could no more afford quinoa and replaced it with less nutritious crops
• Substantial soil degradation and a loss of biodiversity of quinoa varieties ( 3 varieties for 75% production) = monoculture and its associated problems
• Through investment into agricultural research, quinoa is now cultivated in many countries, e.g. USA or DK
Policies needed to avoid harm to food systems and people

Summary • Biodiversity and NUS can improve nutrition, health and food
security based on foods.
• Biodiversity can make the difference between nutritional adequacy and inadequacy and professionals and consumers need to know more about it.
• Biodiversity needs to be mainstreamed into many policies and programmes (Voluntary Guidelines).
• Move to nutrition-sensitive agriculture (ICN2).
• The more biodiversity and diverse diets are consumed the lower the need for fortification and supplementation.
