Food security

  1. 1. FOOD SECURITY South Africa
  2. 2. LANGA
  3. 3. PROBLEM?
  4. 4. PROBLEMS Rapidly increasing population size Lack of space to build new houses Vegetable patches are being converted into land for residential purposes Due to lack of wealth, food is not easily afforded Vegetable gardens are constantly being vandalized
  5. 5. POTENTIAL CONSEQUENCES?
  6. 6. POTENTIAL CONSEQUENCES Reduction in arable land may result in overuse of remaining land Reduction in vegetable gardens will result in less food being produced within Langa Overuse may result in loss of core minerals (which can not be replenished)
  7. 7. POTENTIAL CONSEQUENCES Runoff from pollution and litter will pollute the existing water sources, resulting in less drinking and farming water (It may also cause diseases such as cholera) Once the effects of land misuse have occurred, the land will effectively become useless for agricultural purposes This will result in a lack of food for a large number of people in the community
  8. 8. SOLUTIONS?
  9. 9. SOLUTIONS Use land management techniques to manage farming procedures and natural resources The Honeycomb Project
  10. 10. LAND MANAGEMENT Allocate certain farming zones Change to a different farming zone after each harvest in order to allow the soil to recover. Monitor the conditions of each zone Establish watering systems that are able to operate when needed and save water when not needed
  11. 11. The Honeycomb Project HP
  12. 12. The Honeycomb Project HP Vegetables can be farmed in a greenhouse to provide food for people We estimate that 1 unit will be able to feed between 3 to 5 families A unit will be able to produce fish and vegetables Our self-sustaining unit will allow more land to be used for houses Families can sell excess food in order to buy other foods in order to have a balanced diet

  15. 15. The Honeycomb Project COSTS 12 x 3 meter container R20 000 12 x 0,85 x 0,4 meter fish tank R1 500 Greenhouse film R6500 Growing racks R6000 Water sprinklers and timer R500 Water pump R2000 50 watt solar panel/turbine R500 Other costs (delivery, construction etc.) R8000 TOTAL COST R45 000 HP
  16. 16. The Honeycomb Project Households that do grow their own food, spend on average R350 per month on food purchases HP FINANCES Each family can save R300 per month if they grow their own food Households that don’t grow their own food, spend on average R650 per month on food purchases We estimated that our unit can provide food for 3-5 families. This means that our unit can save approximately R1200 per month. Which is approximately R14400 per year. Therefore, after 3 years, the unit will have saved just under R45000, which is how much it cost to build the unit.
