    • 1. LAND AND FOOD ISSUES
    • 2. ALLEVIATING HUNGER
      Land Quality
      Land Policy
    • 3. LAND QUALITY
      Good and bad land issues
      Methods of improving cultivation
    • 4. LAND QUALITY
      Good and bad land issues
      High potential for increase land cultivation in undeveloped areas.
      2/3 of arable land inAfrica is currently not being cultivated
    • 5. LAND QUALITY
    • 6. LAND QUALITY
      Good and bad land issues
    • 7. LAND QUALITY
      Methods of improving cultivation
      Educating women in farming techniques
      Roots sustainable agriculture systems
      Gathering food from our feet
      For pest control, fallow natures lead
    • 8. LAND POLICY
      Politics
      Unused land
    • 9. LAND POLICY
      Politics
      The impact of political liberalization
      Land and conflict in Africa
      Land in the agricultural economy
    • 10. LAND POLICY
      Unused land:
      Increased
      offshore
      private
      ownership
    • 11. LAND POLICY
      35,778,800 hectares or 86 million acres
      Africa size = 7.04 billion acres
       
      Current arable land = 1.5 billion acres
      6% of arable land is owned by other countries
    • 12. SUSTAINABILITY
      Land degradation
      Total Land Use
    • 13. LAND DEGREDATION FACTORS
      Approximately 40% of the world’s Agricultural land has been significantly degraded
      Nutrient Depletion
      Soil Salinization
      Deforestation
    • 14. LAND DEGREDATION FACTORS
    • 15. LAND DEGREDATION FACTORS
      Nutrient Depletion
      Over-Intensive cultivation and poor soil maintenance can limit the topsoil’s ability to replenish itself.
      Slash and Burn and Soil Salinization are just two example of this
      Since the 1880’s over one half of the U.S.’s topsoil has disappeared
    • 16. LAND DEGREDATION FACTORS
      Soil Salination
      Cheap, potassium based fertilizers for natural salts on the surface of usable land
      Most water carries traces amount of salt. Poorly drained irrigation systems and saline watering systems accumulate surface salts and reduce the amount of nutrients future plants will be able to absorb.
    • 17. LAND DEGREDATION FACTORS
      Deforestation
      Slash-and-Burn Tactics cut down trees to create temporary agriculture, but ruins the land for long-term use.
      Urban sprawl and commercial development takes up much or the arable land around populated areas as it worth more developed than for agriculture
    • 18. TOTAL LAND USE
      In theory, the minimum amount of land it would take to support a person if everyone on earth had a diversified diet like that of the U.S. and Europe is .5 hectares. That’s about the size of a football field. If everyone on earth actually did use the same amount of land for food, however, they would only be able to use .07 hectares per person, with a strictly vegan and limited diet.
    • 19. TOTAL LAND USE
    • 20. TOTAL LAND USE
      Livestock takes considerable amounts of land to produce- approximately 30% of the earth’s total landmass and 40% of all agricultural output.
      Overgrazing and grain-fed livestock are major factors to soil erosion in the U.S. as well.
    • 21. TOTAL LAND USE
      Effective crop rotation can mitigate land degradation effects and maximize land use
      This, however, isn’t as profitable at larger scales, as more profitable crops can’t be maximized. Arizona soy and cotton cycles are an example of this.
    • 22. METHODS OF IMPROVEMENT
      Smaller scale agriculture with private, short term incentives can mitigate land degradation and productivity losses
      Offsite environmental and economic impacts, however, still need larger policy management, especially in a poor performing market
