primary economic activity

• Primary sector is the first stage of production, where raw materials are extracted from natural resources.
• farming,fishing and forestry are examples of primary economic activity
• climate has a major effect on the physical landscapes eg.hot climate=desert area
• height:mountainous areas influence farming,weather,human activity
• sea coasts:coastlines are influenced by erosion process of the sea
• human activity: humans can change the physical landscape eg.planting flowers
• types of farming

  • pastoral farming
  • arable farming
  • mixed farming
  • forestry
• pastoral farming: farming of animals for meat and milk, best suited for flat fertile land
• arable farming is farming that uses land for growing crops, such as wheat, corn, and rice
• mixed farming is when farmers grow crops and keep animals on the same farm
• forestry: planting, growing, harvesting, and managing trees.often planted on the lower slopes of mountains
• farming in Dublin-physical factors

  climate-cool temperature oceanic climate.

  not too hot in summer

  not too cold in winter

  Soils-soils in dublin are very fertile[brown earth soils]-perfect for farming

  height/slope-dublin is relatively flat except for dublin mountains in the south

  farming in the south of the county- mainly cattle grazing and forestry due to mountains
• fishing is an important industry for areas where the soil is not good fertile enough for farming eg castletownbere,co.cork
• sustainable irrigation in New zealand: irrigation helps bring water to areas that does not have enough water and may experience drought

  eg.the water can be transported by pipes and canals
• overfishing: even though fish are renewable,they are being overfished.

  this can lead to species becoming extinct.
• why is over fishing happening?

  1. improved ships: supertrawlers can catch a large amount of fish
  2. technology: supertrawlers have a sonar equipment that can easily locate larger groups of fish
  3. cranes:motorized cranes can haul in huge nets of fish
  4. nets:nets have small holes so small fish cannot escape to reproduce.
• aquaculture:a sustainable way of fishing and farming fish eg.fish farm
• forestry

  a sustainable forest is carefully managed.trees that are cut down and are replaced immediatly.

  illegal deforestation is a major problem.

  {it damages the local economy for communities who rely on forestry}

  increased demand for food means that forests are being cut down to mkae farms.
