Building the Evidence Base & Varieties to Achieve Impact with Vitamin A rich sweetpotato

  1. 1. Building the Evidence Base & Varieties to Achieve Impact with Vitamin A rich sweetpotato MARIA ANDRADE Foundation Day and Consultation on Farming System for Nutrition MSSRF, Chennai August 7-9, 2017
  2. 2. Out of a world population of 7 BILLION • About 2 BILLION suffer from micronutrient deficiency • About 800 MILLION suffer from calory deficiency About 70% of African make a living through agriculture Most farmers are smallholders, poor & malnourished To feed 9 billion humans who’ll be living on Earth in 35 years We need to double the amount of food available on less land
  3. 3. Progress made in Africa, challenges of diet-related premature death, poor development and disease remain. In Mozambique, 43 percent of children under five are stunted due to chronic illness and poor diets. Only one out of every 10 children under two receive the sufficient nutrients they need to be able to grow and develop to their full potential. Alone, child undernutrition costs the country 62 billion MZN, or 11 percent of its annual GDP in Mozambique. Progress has been slow, especially in light of recognition by government that nutrition matters. Our focus must shift from feeding people to nourishing them. In doing so, we must harness the power of the public and private sectors, and civil society to encourage and enable consumers to access better diets. It is imperative therefore that policy makers pay more attention to food systems if nutrition planning is to be effectively implemented. The reality is complex.
  4. 4. Drought is a problem 1. Integrate and align water and soil management strategies to maximize response to drought together with breeding effort for nutrient dense crop 2. Promoting water conservation and more resilient water supplies 3. Improve nutrient and water supplies where yields are lowest Use Resources more efficiently Improve the resilience of the native biodiversity Improve seeds, private sector investment, training
  5. 5. Elimination of hunger and malnutrition require more than transforming the production of food • There is need to assist small holder farmers to build resilience to natural disaster and climate change • Use of advances in science and technology to boost yields • Make partner with the private sector to reach the market • Strengthening in breaking through technologies such as climate resilient seeds, cultural management and improve communication
  6. 6. Some general facts – of Sweetpotato In few countries a staple - in many countries secondary 30 countries are producing 99% of the total world sweetpotato production – but sweetpotato is produced in more than 110 countries of the world Sweetpotato produces more food calories per unit area per unit time than any other crop 15 t/ha (poor soils) to 25 t/ha (good soils are possible with currently available varieties Live saver or poor man’s crops / an image that is gradually changing nowadays. Classic food security Incredible amount of genetic diversity
  7. 7. Mashed OFSP – for puree and or for bread production Need 1: The moist sweet to high dry matter early bulking OFSP (Tumwegamire et al. 2016) Need 2: The animal feed SP in Asia and parts of SSA Need 3: Non-sweet sweetpotato -> taste like potato Need 4: Ready to eat (gari, porridges ) in mixture New Uses & Markets => more / different needs from breeding Bread made with a ratio of 66% wheat flour and 34% mashed OFSP in Mozambique 2009 => bio / fortified bread Selection for long stems & leaves (China 2008) – appears like young bean pods – Uganda 2008 sweetpootato as animal feed (Java / Indonesia 2014 – a cheap fodder crop)
  8. 8. Orange-fleshed Sweetpotato (OFSP): The Model for Biofortified Crops with a Visible Trait * Higher yielding * Rich in Beta-Carotene * Earlier maturing §All types good sources of vitamins C, K, E and several B §Most varieties in SSA white-fleshed: no beta-carotene §100 gms (one small root) meets daily vitamin A needs of a young child Evidence at the Community Level: OFSP contributed 35% of vitamin A intake 15% decline in prevalence of vitamin A deficiency in under 5s
  9. 9. Investing in Orange Fleshed Sweetpotato (OFSP): Was it Worth the Investment? An Experience of 20 Years 1997-1999 Adaptation trials of first generation (68 clones) April 1999 1st multi-sectorial meeting where spoke on the potential of OFSP June 1999 1st strategy to fight the deficiencies of Micronutrients
  10. 10. Opportunity of Development Emerging from Disaster (floods of 2000 2000 Release of 9 varieties 1st generation 2000-2002 Distribution after flood to 120,000 HHs 2003-2006 Integration into development programs for dissemination (700,000 HHs) 1st Nutrition Sensitization Campaign
  11. 11. Intensive Research & Discovering the Need to Initiate a Breeding Program in Mozambique 2003-2005 Towards Sustainable Nutritional Improvement (TSNI) study in Zambézia: Demonstrated the effectiveness of integrated nutrition- agriculture intervention Using OFSP 2005 Severe drought , 2/3 of the country affected. More than 50% of sweetpotato lost (both white & orange) DROUGHT 2003-2004 Problems of localized drought: started looking for fund to initiate a breeding program in the country
  12. 12. The Breeding Program with Emphasis on Selecting Material Tolerant to Drought & Rich in pro-Vitamin A 2006-2010 Develop new varieties of OFSP More adapted to Mozambican conditions N 4 years instead of 8 years! 1) Exploit the characteristics of a vegetative propagated crop 2) More sites, earlier in the process 3) NIRS machine to evaluate nutritional quality of each sample in 2 minutes 3) Evaluate 5,000 clones annually per site N New methodology Accelerated B Breeding 2007-2010 Intensive study Reaching End Users in Zambézia: How to reach many HHs in a cost effective way
  13. 13. A Great Result: 15 New drought tolerant OFSPVarieties Released in February 2011 Result ,,,,,,,,,,,,,,,,,,,,,,,,,,,, The material is from Mozambique but also will help other African countries
  15. 15. Breeding in Africa for Africa § "Accelerated" sweetpotato breeding approach to produce varieties in 3-4 years instead of 7-8 years § By 2016, 42 OFSP varieties bred in Africa released being 20 released in Mozambique The Speedbreeders at crossing block A controlled cross
  16. 16. Storage root yield (t/ha) on dry matter basis

  21. 21. Resilient OFSP. The two crops planted the first cropping season in Maniquenique station, Chibuto district, Gaza Province, October 25, 2016
  22. 22. 17 priority countries, 3 sub-regions 2.9 million Households reached by Sept 2016 12 with Activity under SPHI Umbrella
  23. 23. How are we Going to Disseminate an OFSP to Have Impact in the Nutritional State (VAD)? TSNI Study (Towards Sustainable Nutritional Improvement) Find if it is possíble to have an impact at the level of uptake of vitamin A and nutritional status of the child through the introduction of OFSP varieties combined with an intensive program of demand creation of food rich in in vitamin A and to change food habit in children under 5 years
  24. 24. Access to Improved Planting Material Buy more Vitamin-A-Rich Foods & Health Services Vitamin A Deficiency & Low Caloric Intake in Young Children Conceptual Framework Increase Young Child Feeding Frequency Empowerment Through Knowledge Substitute white- fleshed with orange fleshed, beta-carotene rich varieties Earn income from sales of roots & processed products Produce more Calories & Beta-Carotene per hectare Improved agronomic practices to assure year- round supply Effective feeding practices developed via consultative research Media campaign to increase demand for vitamin A rich foods Enhanced Purchasing Power Increase Young Child Intake of Calories & Vitamin A Improve Young Child Vitamin A Status Deworming
  25. 25. There was significant impact in the adoption of OFSP, the level of vitamin A consumption & the level of vitamin A in the body (blood) § Median intake of vitamin A was 8 times higher in the children under intervention when compared with control § OFSP contributed 35% of vitamin A intake and 6% of energy. § Decreased of 15% in the prevalence of vitamin A deficiency (indicated by low level of serum retinol) Low, JW et al., Journal of Nutrition 137: 1320-1327, 2007
