3. Water on the Earth
1. Begin by reflecting on the need for water in the world. If you can,
find out about the United Nations Millennium Development Goals.
Goal 7C is related access to drinking water.
2. Look for information on the importance water in general for our
society. For example, news related to water scarcity in Spain and the
areas which have been most badly affected throughout history and
the implications, especially in the summer months, when there is
more risk of drought and forest fires.
3. Decide which group of the population or service that uses water
your group will represent. Then, analyse the consequences of water
restrictions. For example:
❚
Farmers would lose crops that would put their livelihood in
danger.
❚
Water parks and public pools would close, which would affect
our leisure activities and our enjoyment at the hottest times of
the year.
❚
The lack of water to drink, to clean homes and for personal
hygiene could affect our health.
Procedure
Drop by drop… it’s disappearing

Imagine that in the area where you live there is a period of prolonged
drought and that the supply of drinking water may soon be at risk.
You are going to form a round table of experts, to examine
the situation and propose different measures of conserving and
using the available water.
Form teams of experts of four or five students. Each one represents a
specific segment of the population or people who work in services that use
water. These could be:
❚
A farmer who needs to water his crops.
❚
The manager of a water park who needs water to fill the swimming
pools.
❚
A family who needs water to drink, clean the house, wash clothes,
shower, etc.
❚
The town hall that needs water for the gardens, streets and fountains.

Water is essential for the survival and well-
being of humans, and it’s important for many
economic sectors of the economy. Water
resources are distributed unevenly in space and
time, and are overused due to human activities.
How can we satisfy a demand that grows every
day?
Summary of the second report from
the United Nations on the development of
water resources in the world:
Water, a shared responsibility
