Primary Economic Activity
Taking resources from the land or the sea
Economic Activity
•
Economic Activity can be divided into 3 categories. These are;
•
•
•
1. Primary Economic Activity
2. Secondary Economic Activity
3. Tertiary Economic Activity
•
What is Primary Economic Activity?
•
Primary economic activity involves taking natural resources from the land or
the sea.
•
•
Q. What is a natural resource?
Q. What natural resources are available from the land or the sea?
Primary Economic Activity

Types of Natural Resources
• There are 2 types of natural resources.
– 1. Renewable resources
– 2. Non-renewable resources
Q. How do you think these types of resources are different?
Renewable Resources
• Renewable resources are resources that can be used over and over
again. With careful management, they will not run out.
• For example, if we cut down trees to make wood, we can plant new
trees to take their place.
• Q. Can you think of any other examples?
• Other examples include water, fish, plants/crops.
• Q. Explain why these examples are renewable resources.
Non-Renewable Resources
• Non-renewable resources are resources that can only be used once.
Each time such resources are used less of that resource is left for
the future. Non-renewable resources will eventually run out.
• Q. Can you think of any examples of non-renewable resources?
• Examples include coal, oil, gas, and peat.
• Q. Explain why these examples are non renewable resources.

natural resource. It is
important that we do not
waste water.
• Q. Estimate how much
water you use per day.
• Q. Discuss things you
could do to conserve
water.
Irrigation Projects
• Crops need water to grow.
They normally get the water
when it rains.
• In places where there is little
rainfall, irrigation is needed.
• Irrigation means pumping
water from a river or lake to
farmland. The water is then
sprinkled over the crops.

Renewable Energy Sources
•
We know that oil is a non-renewable resource. So are most of the other
ways we get energy. Coal, peat, gas etc.
•
Therefore, we need to both conserve energy and also to try to make more
use of renewable energy sources. There are many different types of
renewable energy sources.
•
Q. Can you name any renewable energy sources?
•
Examples include;
•
•
•
•
•
1. Hydroelectricity
2. Solar power
3. Geothermal energy
4. Tidal energy
5. Wind Energy
•
Q. Which of these renewable energy sources could we make use of in
Ireland?
Renewable Energy Sources
Hydroelectric Power (HEP)
•
Hydroelectric Power is created using the power of falling water. A dam is
built across a river to trap the water. When part of the dam is opened the
water rushes in. The water is used to turn a turbine which creates electricity

Solar Energy
•
Solar energy uses the
power of the sun to
create electricity.
•
Heat and light from the
sun are captured by
solar cells.
•
The cells convert the
heat and light to
electricity.

Geothermal Energy
•
Geothermal energy works
by pumping water down
deep into the earth’s crust.
•
The water is then heated by
hot rocks in the earth’s
crust.
•
The heated water is
pumped back to the surface
where it can be used to
heat homes.
•
The hot water can also be
converted to steam which is
used to turn turbines to
create electricity.

Wind Energy
•
Wind power is becoming
a very popular source of
renewable energy.
•
Wind power has been
used for a long time. The
Dutch built windmills to
pump out the water when
they were creating their
Polders.
•
Modern wind turbines are
very big. They are usually
grouped together in what
is known as a wind farm.
Wind Energy
•
Wind farms are
increasingly being built
out at sea. This is
because it is a windy
location and it prevents
visual pollution on the
landscape.
•
Smaller wind turbines are
also available. They can
be put on top of your
house or school to
generate renewable
energy.
Wind Power

•
Q. Using evidence from the graph, explain how we know wind power is
becoming more popular.
Q. Why do you think wind power is becoming more popular?
Q. ‘Ireland is an ideal place for wind farms’. Discuss.
Fishing – Over Exploitation of a Resource
•
•
•
Fish are renewable resources.
If we catch a fish and eat it, other fish will be born to replace it.
However, in many parts of the world too many fish have been caught. The
number of fish has gone down a lot.
Q. People have always caught fish to eat. Why do you think that the problem of
over fishing has arisen only recently?

How do People Fish?
Most fish are caught in the continental shelf. This means they are caught
around the coast of the continents.
Ireland’s Fishing Ports
•
Ireland has many fishing
ports.
•
Fishing is extremely
important to many of these
small fishing villages.
•
Fishing has been carried
out in these areas for
generations.
Over Fishing
•
•
Over fishing has occurred because fishermen are using large fishing nets to
catch huge numbers of fish.
They are also using what are called Factory Ships which can stay at sea for
long periods. They use high tech radar and sonar to find the fish.
Types of Fish and where they are caught
Sustainable Exploitation of Fish
•
•
Many types of fish are now endangered because of over fishing.
Governments and the EU are trying to limit the amount of fish being caught.
•
They have taken the following steps;
•
•
•
•
•
•
1. Made conservation zones around some countries.
2. Excluded foreign fishing boats from fishing in Irish waters.
3. Reduce the number of fishing boats.
4. Introduced yearly quotas for fish catches.
5. Banned the fishing of some endangered species.
6. Made the fishing season shorter for some types of fish.
Q. Do you think these steps are a positive thing? Why?
Q. Many people are against the quotas. Explain why it may be difficult for some
people to accept these changes.
The Irish Box
•
The Irish Box was a rich
fishing ground.
•
In 2003 it was made
smaller when a
Conservation Zone was
made.
•
Strict quotas have been
implemented in this zone to
help fish stocks to recover.
Fish Farms
•
Fish farming is becoming more and more popular. Salmon are grown in
many fish farms around the coast of Ireland.
Q. What has happened to the value of farmed fish since 1998?
Q. Why do you think fish farming is becoming more popular?
