Guiding Question 17.2

What are the causes and consequences of water scarcity?

Why You Should Care

The water cycle governs where and how much water is cycling over the land. However, wind and weather patterns create areas with plenty of water and other areas with too little water. If you take this pattern and add in that humans use water in different ways (water usage increases with industrialization and ecological footprint), then it is no surprise that water can be scarce in some regions of the world.

Water tends to be scarce in desert regions, but water scarcity is much more common in areas that are poor (economic water scarcity) and areas that have growing populations or are expanding personal consumption (scarcity as “water footprint” increases). As water becomes scarcer, technology that pulls water from deeper groundwater sources will require more energy and expense.

Residents of developed countries benefit from more resources to support infrastructure that provides clean water. Also, those residents consume more products, which will require more water for growing and production.

Providing clean water requires money to not only clean the water, but also distribute it efficiently. This is a very common problem among developing countries. Countries with physical access limitations tend to be those with lower precipitation rates or fewer freshwater sources, and these are less common.

Rural areas have lower population density. The same pipe infrastructure is more costly when people live in lower densities.

Correctly match each sector in the pie chart with its water usage. Then match each type of food and each product with the number of gallons of water needed to produce them.

Since our choices for consumption rely on the food we eat (70% of water used) and the products we buy (22% of water used), water usage is closely tied to what we choose to consume.
