5 Food NUMBERS - Food for thought Total available agricultural land 11% of the surface

1. 5 Food NUMBERS - Food for thought • Total available agricultural land 11% of the surface • 6 billion humans > ca 0.3 hectares per person • Average subsistence (2400kcal p day p person) requires 1 hectare of land with reasonable climate • 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 • Less than ¼ of the World benefits from this agricultural revolution

7. Some consequences • Less than ¼ of the world benefits from this so ¾ still need ca 1 hectare per person but only have ca 0.3 • So over ½ of the human race is struggling with deficient diets and ½ of these are in the grip of chronic malnutrition • 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

12. What are some of the omens? • 60% of the world’ agricultural land is suffering due to salination by forced irrigation, erosion and sea level rise • 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 • Permanent blindness • Respiratory infections • Diarrhoea • Measles • 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
