  1. can the world's by him sustainably feed the world's population?
  2. The real problem with the human population projected to hit
  3. 10 billion?
  4. How are we going to feed the world?
  5. This question drives policy decisions, guides research and development funding
  6. and influences farming choices.
  7. It's a question that is used to justify producing more
  8. food at all costs more factory farms, more monoculture, more
  9. pesticides, more by engineering and more data control.
  10. But the reality is is that we already produce enough
  11. food to feed a growing population, have much of the
  12. food that we produce is wasted, used as animal feed
  13. or turned into biofuel.
  14. The problem is also one of distribution and poverty.
  15. Many people struggle to access the foods they want and
  16. need. So what are the questions we should be asking?
  17. We should be asking, how do we get food to
  18. people who need it in the right quantity and quality?
  19. How can we ensure fair livelihoods for farmers?
  20. How can we produce enough food in a way that
  21. protects the planet?
  22. What exactly is food security?
  23. Food security is a concept that measures whether a country
  24. and its people have physical social and economic access to
  25. foods that meet their preferences, nutritional and dietary needs at
  26. a given time.
  27. Food security isn't just about the amount of food, it's
  28. multi factorial.
  29. Taking into account these four things availability, access, utilization and
  30. stability, bimes producing fruit.
  31. So the environmental factors include turn climate, soil properties and
  32. soil water are all the influence the development of agricultural
  33. yields. Economic factors such as subsidized commodity prices, labor and
  34. immigration laws, cost of land, transport, capital and market impact
  35. farming. Technological factors include machines designed for livestock feeding, irrigating
  36. the land, tilling the soil planting seeds, protecting these very
  37. crops from pests and weeding weeds, cultivating crops, threshing grain
  38. harvesting and sorting and packaging.
  39. The products challenges to food production.
  40. What are the environmental challenges to producing food in Australia
  41. and in other areas around the world?
  42. Climate change is enhancing the frequency and intensity of heat
  43. waves and warmer days in Australia, changing rainfall patterns, increasing
  44. the risks of bushfires and enlarging danger for droughts.
  45. Average precipitation is forecast to further decline in the cooling
  46. season in southern Australia, with the projected increase in times
  47. of extreme drought, scarcity of water, heat stress and increased
  48. climate variability are important risks for our food security economy
  49. and dependent sectors and communities in our most productive agricultural
  50. reasons such as the Murray darling basin.
  51. So how these challenges affected in Australia evidence and aftermath
  52. rainfall division, she's in parts of Western Australia and central
  53. Queensland were projected to decrease in the total National crop
  54. pedestrian by 12% in 2014 and 2015.
  55. And the valley of beef and veal exports by 4%.
  56. Yeah, the first strategy is terrace farming.
  57. Terraced cultivation is a method of developing crops on sides
  58. of hills and mountains, replanting and graduated terraces built into
  59. the slope.
  60. Terrace farming's ensure food security enhances crop yield through the
  61. water and saw a conversation conservation.
  62. The significance of stairs, farming reaches beyond cultivating lands that
  63. are not suitable for the agricultural otherwise terraced farming restraint,
  64. soil erosion and contributes to soil conservation.
  65. This strategy is exceedingly effective in controlling soil erosion as
  66. they intercept rainfall runoff as it starts down a slope
  67. which prevent a large accumulation of float on the surface.
  68. So these are some of the advantages and disadvantages of
  69. terrace farming, an example in both promoting the plant growth
  70. and preserving precious topsoil.
  71. The Fania ju Terraces, a soil and water conservation measures
  72. used to decayed indicate agricultural landscapes have led to the
  73. regeneration of organic material concentrations comparable to those observed in
  74. neighboring similar ecosystems.
  75. Under conventional agricultural practices, farms with these, such terraces store
  76. 1 3rd more organic source than farms.
  77. The funny a jew terraces Have boosted crop yields by
  78. at least 25% in East Africa, contributing to their increase
  79. increasing use.
  80. A second strategy is hydroponic greenhouses.
  81. Now, hydroponic greenhouse systems is growing crops in water, greenhouse
  82. farming and hydroponics are similar to a great extent how
  83. the support system and meth method of providing nutrients and
  84. water to plants is different.
  85. Hydroponic systems employ water and nutrients to cultivate high yield
  86. cultures, utilizing a durable, soil free method, It uses less
  87. water and boost local markets by providing food security as
  88. an agriculture alternative.
  89. The methodology also provides, produces opportunities for additional income in
  90. developing regions.
  91. These are the advantages and disadvantages.
  92. However, the disadvantages don't damage the environment.
  93. My third strategy is global food reserves.
  94. Regional or worldwide food reserves, identify quantities of rice and
  95. other food grains such as maize and corn collected through
  96. purchases or donations from other major producing countries to be
  97. distributed to other members.
  98. In times of scarcity that have a supply deficit caused
  99. by furman's heavy typhoons and infestations of disease.
  100. Food reserves can be valuable to for improving access to
  101. and distribution of food.
  102. They can help farmers predict their markets and counter concentrated
  103. market power from production downstream.
  104. They can help farmers and contribute in areas where resources
  105. is and lacking to local national and regional markets.
  106. Reserve in mentors may compensate for foreign currency shortfalls, offset
  107. supply shocks or demand hikes and facilitate the emergency human
  108. military in response reserves can also assist countries in dealing
  109. with the effects of climate change on food production and
  110. supply. These are the advantages.
  111. Yeah, and that's how science can sustainably feed the world's
  112. population. Thank you
