What are the challenges & opportunities of climate change? EXAM…

- - - - 0.6-1.3 degree by 2030
    - - now 410 PPM
      - Less confident in projection
        
        Due to oceans
    - - 2.6 (very lucky)
      - 8.4 (business as usual)
      - 6.5 (no coal)
    - - Crabon
      - Methane (11%)
      - we ocntribute 17% from agriculture
        
        1/2 life of CO2, CH3, NO2
      - NO2 (fertilizer, legumes...) 300 x worse than CO2
  - - - difference of C3 vs C4
        
        Plant production
        
        Heat stress
    - - More heat
      - Less water
    - - WUE
- - - - Tree planting (short term fix?)
    - - Top down resposnes
      - Bottom up responses
    - - Negative feedback loop
    - - More wind/solar
      - Less carbon fuels
      - efficient Appliences
      - Sundrop farms
  - - - Systemic adaption
        
        Huge changes in system
        
        digital agriculture
        
        PA, robotics
        
        Block chain
        
        app. of digital tech to trace
        
        big data
      - Incremental
        
        Minor changes, tweeking (row spacing...)
      - transfromative
        
        change in land use
        
        increase in urban farming
      - GHG policy
    - - Horticulture
        
        glasshouse (protected cropping)
        
        Phenology
        
        breeding
        
        Irrigation
        
        precision irrigation
      - Livestock
        
        better quality fodder
        
        Nutrition
        
        Genetics for low methane
        
        Vaccines
        
        rumen micro biology
        
        Twins
        
        Climate smart beef (WEBSITE)
      - Grains
        
        Precision Agriculture
        
        Plant breding
        
        robotics (labor, weed control)
      - More head/unit of methane
