  14. 14. 3. Maternal nutrition and the intergenerational cycle of growth failure<br />Can this be made into a virtuous cycle?<br />Figure 1 Intergenerational cycle of growth failure (ACC/SCN 1992)<br />14<br />
  15. 15. 15<br />3. Maternal nutrition<br />YES: LBW RATES CAN BE BROUGHT DOWN SHARPLY<br /><ul><li>Birth weight can be rapidly improved, even in populations of short adult women
  16. 16. Not just more quantity but also improved diet quality (fortification and supplementation) can help achieve this, especially if mother reached during first half of pregnancy (+100g)
  17. 17. yet maternal anaemia rates are very high and little priority given to this (except PROGRESA)
  18. 18. No risk of increased CPD even in adolescent mothers</li></li></ul><li>16<br />3. Maternal nutrition<br />BUT NOT IN YOUNG ADOLESCENTS:<br /><ul><li>improving birth weight in adolescent mothers is best achieved by delaying pregnancy until after 18y.
  19. 19. For each year that median age first pregnancy can be extended beyond 15y to 20y, an additional 1cm could be added to final adult woman's height.
  20. 20. Yet almost half of mothers are married before 18y in LDCs
  21. 21. Beware: Food supplementation of the still growing primiparous pregnant adolescent decreases birth weight and increases risk of maternal obesity
  22. 22. 75% of LIFDC have more overweight than under weight women of reproductive age</li></li></ul><li>17<br />3. Maternal nutrition<br />IMPOVING BIRTH WEIGHT LEADS TO IMPROVED ADULT HEIGHT <br /><ul><li>Birth weight strongly predicts height at two years (Binkin et al 1988)
  23. 23. Height at two years of age largely determines adult height (Cole 2000)
  24. 24. Those born LBW are 5cm shorter at adulthood (Martorell et al 1998)
  25. 25. Half of stunting occurs in uterus and half in first two years of life (Li et al 2003)</li></ul>The GROWTH” WINDOW OF OPPORTUNITY” IS FROM CONCEPTION TO TWO YEARS <br />
  26. 26. 18<br />3. Maternal nutrition<br />PUT BACK THE FFF<br /><ul><li>The UNICEF child survival and development revolution focussed on keeping the child growing along the “path to health” or “child survival” promoting oral rehydration, breastfeeding and immunizations (GOBI) with great success!
  27. 27. The UNICEF nutrition conceptual framework focussed on child malnutrition (not maternal malnutrition)
  28. 28. The revolution would have been even more successful if the original GOBI-FFF had been maintained (UNICEF 1982).
  29. 29. SO PUT BACK THE FFF :
  30. 30. Family planning
  31. 31. Food supplements (Micronutrients) for women during pregnancy
  32. 32. Female education</li></li></ul><li>19<br />3. Maternal nutrition<br />Improved birth weight is a public good!<br /><ul><li>The impacts of maternal nutrition interventions typically dismissed as being “small” , i.e. only 100g
  33. 33. But small increase in birth weight can be magnified across the life course (e.g. 100g in birth weight is 20% reduction in stunting at two years Kusin et al 1998))
  34. 34. Little recognition of the distribution wide effects of improved birth weight (optimal birth weight is ~2 SD above the mean) as for example with cognitive function (Richards et al 2001)</li></li></ul><li>3. Maternal nutrition<br />Why prioritise the protection of foetal and infant growth?<br />Short term<br />Long term<br />Brain <br />development<br />Cognitive and<br />educational <br />performance<br />Nutrition<br />in uterus <br />and early <br />childhood<br />Growth and muscle mass<br />Body composition<br />Immunity<br />Work Capacity<br />Diabetes, Obesity<br />Heart Disease<br />High blood pressure<br />Cancer, stroke, <br />and ageing<br />Metabolic programming of <br />glucose, lipids, protein <br />Hormone/receptor/gene<br />Death<br />Short and long term effects of early nutrition (James et al 2000)<br />
  35. 35. 4. Sustainable Food Security: an overview of some key issues<br />21<br />What is Sustainable Development?<br /><ul><li>When governance mechanisms ensure that the use of natural capital and the creation of physical capital occurs in ways that socially regrettable effects (negative externalities) are minimal.
  36. 36. For this to happen socio economic development must favour human wellbeing, through the development of human and social capital, and not just favour economic growth.</li></li></ul><li>4. Sustainable Food Security<br />22<br />MOST POPULATION GROWTH IS DEVELOPING COUNTRY AND URBAN <br /><ul><li>Although there has been great progress in reducing fertility rates globally, the LDCs are still lagging behind.
  37. 37. DC fertility down from 5 to less than 3, while LDCs fertility is still at 4.5.
  38. 38. The global population, now about 6 billion, will be close to 9 billion by 2050
  39. 39. Most of this population growth will be in Africa and Asia</li></li></ul><li>23<br />4. Sustainable Food Security<br />MOST POPULATION GROWTH IS IN DEVELOPING COUNTRIES AND URBAN AREAS <br /><ul><li>Today about a half of the global population lives in urban areas.
  40. 40. By 2050 over two thirds of global population will be urban and the majority will be living in developing countries</li></li></ul><li>24<br />4. Sustainable Food Security<br />FOOD PRODUCTION IS KEEPING PACE<br />Despite global population doubling in last thirty years the per caput supply of calories for human consumption rose by over 20%.<br />FAO predictions are that Developing Countries are expected to be increasingly well fed, closing the gap on developed countries by 2050<br />
  41. 41. 25<br />4. Sustainable Food Security<br />FOOD PRODUCTION IS KEEPING PACE<br /><ul><li>Although appearing to plateau in early nineties food production has risen again over the last six years
  42. 42. In 2008 food stocks also recovered and climbed back over 500MT for first time since 2001 (FAO 2009)
  43. 43. Production may get over 3 billion tonnes by 2030 if sufficient R&D is applied.
  44. 44. But areas of population growth are not areas where food production can expand</li></li></ul><li>26<br />4. Sustainable Food Security<br />FOOD PRODUCTION IS KEEPING PACE – BUT!<br />But times have changed and “peak oil” means it is no longer cheap. At over $70 a barrel and not $30 of a decade ago, the price of oil becomes one of the main drivers of high food prices<br />It has become as profitable for farmers to grow crops for biofuel as it is to grow them for food<br />The “Green Revolution” which led to the increase in food production was achieved through the : <br /><ul><li>adoption of crop rotation,
  45. 45. the use of mass produced petroleum based fertilizers and chemical pesticides,
  46. 46. the use of petroleum driven machinery,
  47. 47. expanded irrigation, and
  48. 48. the introduction of genetically superior disease resistant cultivars</li></ul>What we need now is a “technological revolution”<br />
  49. 49. 27<br />4. Sustainable Food Security<br />FOOD PRODUCTION AND ENVIRONMENTAL SURVIVAL <br />BUT - Several environmental trends threaten the agricultural production momentum :<br /><ul><li>Soil erosion/desertification
  50. 50. Top soil is being lost quicker than it is being replaced
  51. 51. Genetic erosion
  52. 52. Hybrid seeds mean genetic uniformity is replacing the genetic diversity of food stocks
  53. 53. Freshwater fish stocks in precipitous decline (down 30% since 1970)
  54. 54. Sea fish under threat with 75% of fish stocks fully exploited or depleted
  55. 55. Bird, bees and bats are in retreat
  56. 56. Fresh water scarcity
  57. 57. American Meaty diet needs 5000l/day vs 2000l/day for Asian diet
  58. 58. Most investment goes into withdrawal of underground water and 70-80% is used for irrigation. Extraction levels exceed replacement levels in most places.
  59. 59. Greenhouse Gas Emissions and Global warming
  60. 60. Levels of CO2, Methane and Nitrous Oxide produced on earth are increasing. These accumulate in the atmosphere and help trap the suns energy like in a greenhouse</li></ul>Source: (UNEP GEO4 and IAASTD 2009) <br />
  61. 61. 4. Sustainable Food Security<br />FOOD PRODUCTION AND ENVIRONMENTAL SURVIVAL<br />CH4 now about 1750 ppbv<br /><ul><li>Greenhouse Gas Emissions (GGE)
  62. 62. Are now at higher levels than ever before in the earths history
  63. 63. They are increasing at rates faster than the middle case scenario used for IPCC 2007 predictions </li></ul>CO2 now about 385 ppmv<br />(Source: IAASTD) <br />Greenhouse Gas record from the Vostok Ice Core<br /><ul><li>Greenhouse Gas Emissions (GGE)
  64. 64. Agriculture, and meat production in particular are largest single contributors, together contributing a third of GGE (Fiala 2009) </li></li></ul><li>4. Sustainable Food Security<br />FOOD PRODUCTION AND THE ENVIRONMENTAL SURVIVAL<br />Climate Change<br />The Stern review called for global emissions to be cut by a quarter by 2050 and to be stopped from rising above the equivalent of 550ppm of CO2.<br />The current level is 430ppm, and is rising by 2ppm a year.<br />Countries needed to spend 1% of their GDP on climate change mitigation. Failure to do this would lead to damage costing much more- at least 5% and perhaps more than 20% of global GDP<br />Source: Stern Review<br />(Source: IAASTD) <br />
  65. 65. 4. Sustainable Food Security<br />FOOD PRODUCTION AND ENVIRONMENTAL SURVIVAL <br />THE DAMAGE IS ALREADY DONE (UNEP 2009)<br /><ul><li>Even if concrete steps were taken now to reduce climate change the damage already done means that up to 25% of the worlds food production is likely to become lost due to “environmental breakdowns” by 2050, with the populations of Asia and Africa being most affected. </li></ul>Source: IAASTD<br />40C LIKELY BY 2060 (UK Meteorological Office 2009)<br />This will mean a 2m rise in sea level by 2060<br /><ul><li>Large parts of Bangladesh and Vietnam that now grow rice will likely be under the sea.
  66. 66. Saigon, Mumbai, New Orleans, and Venice for example, are all likely to be submerged</li></li></ul><li>31<br />4. Sustainable Food Security<br />FOOD PRODUCTION AND ENVIRONMENTAL SURVIVAL <br />Food Supply is not well used <br />“Quantity not Quality”<br /><ul><li>The large scale industrial processing of food, on the one hand allows fortification to prevent deficiency (iodized salt), but on the other hand also contributes to the escalation of chronic degenerative diseases (high energy density, cheap foods, saturated fats, etc).
  67. 67. 1/3 of grain production feeds animals
  68. 68. Trend towards increased meat/animal fat consumption and less vegetable consumption has negative health consequences (obesity, etc).</li></ul>“Waste not want not”<br /><ul><li> Over half of food produced globally is lost
  69. 69. In developing countries ~40% of harvest lost due to pests and pathogens
  70. 70. In UK 1/3 of food purchased is thrown away
  71. 71. In Australia ½ of landfill is food waste.
  72. 72. Globally 30 million metric tonnes of fish are discarded at sea
  73. 73. In Africa 30% of fish landings are lost</li></li></ul><li>32<br />4. Sustainable Food Security<br /><ul><li>Economic Threats and Opportunities</li></ul>Growth of global material wealth has been enormous in the last 2 centuries - even if very uneven<br /><ul><li>While global population increased 6x since 1800, per capita income has increased 9x (Sachs 2005)
  74. 74. Global economic activity increased 49x times in this period, but economic growth has been highly uneven.
  75. 75. Today there is 20xgap between the USA, the richest economy, and the poorest region Africa, compared to a 4x gap a century ago.
  76. 76. And as the figure shows the gap is widening</li></ul>Source: Ghosh J and Chandrasekhar CP. 2008. Global GDP growth: a longer view. <br />

  78. 78. Global economy is expected to shrink by 1.7% in 2009.
  79. 79. On an annualized basis, global GDP growth slowed to 2 percent after averaging 5 percent over 2003-07.

Global Economic Prospects: Commodities at the crossroads. Washington: The World Bank<br />But developed countries are hardest hit<br /><ul><li>GDP in rich countries is projected to contract by 3.8 percent in 2009, as against 0.9 percent growth in 2008.
  81. 81. Growth in developing countries is projected to slow to 1.6 percent in 2009, compared with 6.1 percent growth in 2008.
  82. 82. Gross domestic product (GDP) growth in developing countries is expected to slow to 2.1%, and recessions are projected in Europe and Central Asia (-2.0%), and Latin America and the Caribbean (-0.6%). </li></li></ul><li>4.

  85. 85. 35<br />4. Sustainable Food Security<br />Economic Threats and Opportunities<br />Source: UNEP 1990<br />Source: . FAO 2009<br />The period of cheap food that has characterized the last two decades is evidently over. <br /><ul><li>The Food Price Index (FPI) of FAO has fallen progressively since the 1974 oil crisis. But in 2007 the FPI jumped 26% followed by another 24% increase in 2008.
  86. 86. Although the FPI has decreased 25% since it peaked in mid 2008, the price of food as measure by the new Global Food Consumption Price Index (GFCPI) has dropped less and is still about 50% over 2006 levels</li></li></ul><li>36<br />4. Sustainable Food Security<br />Economic Threats and Opportunities<br />The number and proportion of undernourished has increased<br /><ul><li> In the period 2007-2009 the proportion of the global population that is undernourished increased for the first time in four decades.
  87. 87. The surge in food prices since 2002 wiped out much of the global gains in hunger reduction achieved over the previous two decades.
  88. 88. About 1 billion people were undernourished in 2009, with most of these hungry people are in South Asia and sub-Saharan Africa
  89. 89. Many more face qualitative dietary inadequacies, with serious consequences for mothers as explained in the maternal nutrition chapter. </li></li></ul><li>37<br />4. Sustainable Food Security<br />Economic Threats and Opportunities<br />Increasing global unemployment requires the strengthening of social protection programmes in developing countries<br /><ul><li>Global unemployment rate rose to 6% in 2008 with an estimated 190 million unemployed, and this will increase furthermore in 2009; in addition some 90 million people will enter the labour market worldwide in 2009-10. (ILO 2009)
  90. 90. Only 20% globally have adequate social security, and 50% lack any type of protection.
  91. 91. In Sub-Saharan Africa and South Asia 90% lack any social security coverage
  92. 92. Conditional cash transfers (CCTs) programmes are increasingly seen as one of the most effective ways to spearhead the development of social protection programmes in developing countries
  93. 93. Furthermore CCTs can accelerate the reduction of maternal and child undernutrition and contribute to fertility reduction</li></li></ul><li>38<br />4. Sustainable Food Security<br />WHAT CAN BE DONE TO ENSURE SUSTAINABLE FOOD SECURITY?<br />The Environmental Food Crisis Report (UNEP 2009) <br /><ul><li>warns that simply ratcheting up fertilizer and pesticide led food production of the past will only undermine sustainability
  94. 94. Recommends a revolution in food production that can boost yields by working with rather than against nature. </li></ul>The IAASTD Report concludes that:<br /><ul><li> a fundamental shift in agricultural knowledge science and technology (AKST) is required, which give increased importance to the multifunctionality of agriculture, and recognises farming communities, farm households and farmers as producers and managers of ecosystems
  95. 95. This shift may call for changing the incentive systems for all actors along the value chain to internalize as many externalities as possible, and so reduce the “socially regrettables”. </li></ul>The concept of food sovereignty as proposed by “La Via Campesina” may well offer the most sure way ahead. (Rosset P 2008.)<br />
  96. 96. 39<br />4. Sustainable Food Security<br /> WHAT CAN BE DONE TO ENSURE SUSTAINABLE FOOD SECURITY?<br />The Environmental Food Crisis Report (UNEP 2009) makes seven major recommendations: <br />Regulate food prices and provide safety nets for the impoverished, <br />Promote environmentally sustainable higher-generation biofuels that do not compete for cropland and water resources, <br />Reallocate cereals used in animal feed to human consumption by developing alternative feeds based on new technology, waste and discards, <br />Support small-scale farmers by a global fund for micro-finance in developing diversified and resilient eco-agriculture and intercropping systems, <br />Increase trade and market access by improving infrastructure, reducing trade barriers, enhancing government subsidies and safety nets, as well as reducing armed conflict and corruption, <br />Limit global warming, <br />Raise awareness of the pressures of increasing population growth and consumption patterns on ecosystems. <br />
  97. 97. 40<br />4. Sustainable Food Security<br />WHAT CAN BE DONE TO ENSURE SUSTAINABLE FOOD SECURITY?<br />The Comprehensive Framework for Action (CFA) of the High Level Task Force on the Global Food Security Crisis, <br />The CFA covers most of these recommended actions. However the mitigation of climate change dimensions should be given much more priority and eminence. The context of a “food price crisis” is changing to one of an increasingly serious “environmental food crisis” and should include family planning and special attention to adolescents <br />As noted by the Special Rapporteur on the Right to Food, the CFA could be strengthen considerably if it used as a reference the obligation of all States and the UN agencies to contribute to the realization of the human right to adequate food. <br />Such an inclusion would allow: <br /><ul><li>consideration of the relationship between their obligations under trade agreements and the human rights obligations to respect, protect and fulfil the right the food;
  98. 98. the focus on smallholder farmers in response to the current crisis;
  99. 99. the obligation of all States to contribute to establishing an international environment which enables each State to respect, protect and fulfil the right to food. </li></li></ul><li>41<br />4. Sustainable Food Security<br />WHAT CAN BE DONE TO ENSURE SUSTAINABLE FOOD SECURITY?<br />Certainly business as usual is not an option<br />
