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.
