1 5 Food NUMBERS - Food for thought 1.Total available agricultural land 11% of the surface 2.6 billion humans > ca 0.3 hectares per person 3.Average subsistence (2400kcal p day p person) requires 1 hectare of land with reasonable climate 4.Industrialisation of agriculture (synthetic fertilisers, pesticides tractors, electrification transport etc) has resulted in an increase in productivity such that 1 hectare presently produces enough food for 10 people 5.Less than ¼ of the World benefits from this agricultural revolution

7 Some consequences 1.Less than ¼ of the world benefits from this so ¾ still need ca 1 hectare per person but only have ca 0.3 2.So over ½ of the human race is struggling with deficient diets and ½ of these are in the grip of chronic malnutrition 3.WHO estimate 250 million pre-school children suffer from VitA deficiency which manifests itself as xerophthalmia and often results in blindness That’s today the future is ominous

10 That’s today the future is ominous

11 That’s today the future is ominous

12 What are some of the omens? 1.60% of the world’ agricultural land is suffering due to salination by forced irrigation, erosion and sea level rise 2.By 2020 8 billion people estimate

23 Another major problem: 40% of the world exist on rice Traditional edible rice contains no carotenoids This results in Vit A deficiency which can result in 1.Permanent blindness 2.Respiratory infections 3.Diarrhoea 4.Measles 5.Growth problems Two genes from the daffodil which code for the enzymes which produce beta carotenoid can be inserted into rice DNA which then grows containing beta carotene
