1. ECONOMIC ACTIVITIES
Economic activities are classified into three main sectors: primary, secondary and tertiary.

2. PRIMARY SECTOR

3. 1. AGRICULTURE
Agriculture obtains fruit, vegetal, and cereal products from the earth for people or industry.

4. FARMING SYSTEMS BASING ON THE WAY TO FARM
BASING ON THE USE OF WATER
BASING OF THE USE OF SOIL
BASING ON THE VARIETY OF SPECIES

5. BASING ON THE USE OF WATER
A. IRRIGATED AGRICULTURE
Crops receive water from artificial irrigation systems.
Common in: fruit trees, cotton, breetroot adn vegetables.

7. BASING ON THE USE OF WATER
B. RAIN-FED AGRICULTURE
Crops just receive water from rainfall.
Used for cereals (wheat, barley, rye), pulses (lentils, soya) vines, olive trees and sunflowers.

10. BASING ON THE USE OF SOIL
A. INTENSIVE AGRICULTURE
High investment in capital machinery, seeds and fertilisers to get maximun yield.
2 types:
High productivity intensive agriculture
Low productivity intensive agriculture

11. A. INTENSIVE AGRICULTURE
High productivity intensive agriculture
Very few people work, but needs high investment.
Common for crops with commercial purposes:
Garden produce
Greenhouse (under plastic)

14. A. INTENSIVE AGRICULTURE
Low productivity intensive agriculture
Many people working, but no money is invested
Best example: Asian paddies

15. B. EXTENSIVE AGRICULTURE
It does not use all the resoures ro obtain the maximun yield.
The more land is cultivated, the more yield they have.
2 types:
High productivity extensive agriculture
Low productivity extensive agriculture

16. B. EXTENSIVE AGRICULTURE
HIGH PRODUCTIVITY EXTENSIVE AGRICULTURE
Importance of technology.
Common in large cereal fields of USA.

17. B. EXTENSIVE AGRICULTURE
LOW PRODUCTIVITY EXTENSIVE AGRICULTURE
Techniques are basic
Usual in non-developed areas

18. BASING ON THE VARIETY OF SPECIES
MONOCULTURE: just one species
POLYCULTURE: several species are grown in the same area.

19. LIVESTOCK FARMING
It is the farming that obtains different products from animals (eggs, wool milk, meat, etc)
Types:
Cattle
Sheep/coat
Rabbits
Horses
Poultry (chickens, ducks, turkeys,etc)

20. Deppending on the capital investment
EXTENSIVE LIVESTOCK:
Low investment
Productivity low

21. Deppending on the capital investment
INTENSIVE LIVESTOCK:
High investment
High productivity

22. Deppending on feeding methods
GRAZING LIVESTOCK: grass
CONFINED LIVESTOCK: feed
SEMI CONFINED: summer: grass; winter: feed.

23. Deppending on mobility
Nomadic

24. Deppending on mobility
TRANSHUMANCE

25. Deppending on mobility
SEDENTARY

26. FOREST EXPLOITATION
The utilitation of forest products: resin, cork, timber, etc
A. TIMBER: furnitures, planks, etc.

27. B. CORK: bottle corks, insulating board.

28. C. RESIN: chemical products.

29. FISHING
It is the practice of catching fish and other marine species for food or as raw materials for industry.

30. Two types of fishing Coastal fishing.
It is done near the coast (on the continental shelf) during one or several days.
Boats that follow this type are small and techniques are artisanal.
Off-shore fishing and deep sea fishing.
It is done in deep sea areas during several weeks (off-shore) or months (deep sea).
Boats are large and there are also freezer factory ships

31. LONGLINE FISHING

32. Techniques for fishing:
TRAWLING
LIFT NETTING
AQUACULTURE

33. TRAWLING

34. LIFT NETTING

35. AQUACULTURE
