Topic 5: The Water Cycle and Water Insecurity
Water plays a key role in supporting life on earth. The water cycle operates at a variety of spatial scales and also at short- and long-term timescales, from global to local. Physical processes control the circulation of water between the stores on land, in the oceans, in the cryosphere, and the atmosphere. Changes to the most important stores of water are a result of both physical and human processes. Water insecurity is becoming a global issue with serious consequences and there is a range of different approaches to managing water supply.
- Enquiry question 1: What are the processes operating within the hydrological cycle from global to local scale?
- Enquiry question 2: What factors influence the hydrological system over short- and long-term timescales?
- Enquiry question 3: How does water insecurity occur and why is it becoming such a global issue for the 21st century?
