Resource 6: Evidence of global warming in Ghana

Background information / subject knowledge for teacher

The following symptoms provide evidence that global warming is occurring in Ghana:

  • decreased rainfall, increased temperature and evaporation in dry areas;
  • frequent spells of drought leading to water shortages;
  • changes in planting dates of annual crops;
  • increased fungal outbreaks and insect infestations due to changes in temperature and humidity;
  • decrease in forest area and area under cultivation;
  • decline in crop yield.

The potential effects of global warming in Ghana are:

  • increased risk of food shortage and famine;
  • reduction in ecosystem integrity and resilience, and decline in biodiversity;
  • increased potential of malaria transmission, resulting in burdens on the country’s health care system.
