Step 1
AO1: Knowledge and understanding of changes of the water cycle
Answer
Climate change is expected to alter the water cycle significantly, leading to variations in precipitation patterns. This could include increased variability with prolonged dry spells and sudden heavy rainfall events. The influence of seasonal changes and human activities, such as farming and water abstraction, will exacerbate these changes, affecting the natural water cycle and the overall availability of water in the ecosystem.
Step 2
AO2: Application of knowledge to show how changing rainfall characteristics impact life
Answer
The predicted decrease in the number of days suitable for plant growth will likely lead to reduced agricultural yields, impacting food supply and livelihoods. In areas projected to experience less than 60 days of optimal growth conditions, farmers may find it increasingly difficult to sustain their crops. Additionally, the ecological balance may be disrupted due to less vegetation cover, leading to soil erosion and loss of biodiversity. Such changes are expected to heavily influence local communities, affecting their daily life, economic stability, and food security.
