6.6 Conclusions
  • Conditions that determine crop growth are intrinsically liked to the climate and the environment; changes are likely to impact on crop growth.
  • Uncertainty exists about the predicted impacts of climatic change, although some positive and negative impacts are expected.
  • The scale of impact depends on the degree to which climate changes.
  • Some changes in crop production and fish migration have already been observed.
  • Without mitigation or adaption, the impacts on food production, overall, are expected to be negative, although regional differences will occur.
  • Poorer countries will be affected most because:
    • Climate change will affect those regions most severely.
    • Poor people and lower-income nations are less able to adapt to changes in climate (e.g. by investing in the necessary infrastructure or training); afford higher food prices; or cope with price and supply volatility.
