Global Water Sources & Water Use
​

Starter:  Complete the tasks on this worksheet. 
Objective: To be able to describe the uses made of water for agriculture, domestic and industrial demand

Agriculture is by far the World's biggest user of water. Water is used for animals, but the majority is used for irrigation. The amount being used by agriculture is also increasing as the World's population increases and the demand for food increases. Household or domestic use in the next biggest user. The most water is usually used in toilets, but also washing machines and shower/baths use significant percentages. Industry and energy production also uses large percentages in manufacturing and cooling processes. The fourth biggest user is actually water lost through evaporation and leaks in reservoirs.

Economic water scarcity: This is when water is available, but for some reason it is inaccessible or unusable. This might be because it is groundwater that is expensive to extract or that the cost of transporting it is too expensive or simply that the supply of water has become polluted.



Physical water scarcity: This is when there is not enough water available. The most common reason for this is low precipitation rates.

Water  Shortage - (refer back to Sahel)


​There is no new case study work to complete here. We have already covered this section in the Deserts work in the Natural Environments unit where we looked at water shortage (drought) in the Sahel region of Africa. Your revision for that will also come in handy for this unit of work too. Click on the image below to be taken back to the work on drought (you need to scroll down towards the bottom of the page).
