      3. Depend of the mechanisation and technological development
    2. Polyculture
      1. Areas divided into a number of plots
      2. Tipycal in low-productivity and traditional agriculture
  2. Dry and irrigation farming
    1. Irrigation farming
      1. Waters come from aquifers, rivers...
      2. obtain higher yields that dry farming
    2. Dry farming
      1. Crops watered by precipitation
  3. Intensive and extensive farming
    1. Extensive farming
      1. Land is left fallow
      2. It depends of mechanisation, fertilisers, etc
    2. Intensive farming
      1. The land produced very high yields
      2. It is made to produce several crops a year by using irrigation, greenhouses and fertilisers
2. Factors
  1. Nature-related factors
  2. Human factors
    1. Biological techniques
    2. Chemicals
    3. Moderns plinker and drip irrigation

  2. Intensive
    1. Animals in farms to feed then
    2. Monitory by vets
    3. Very high yields
Forestry
1. Types
  1. Pollarding
    1. It involves periodically pruning only the branches of the trees
    2. The trees continues producing wood
  2. Thinning
    1. Limited number of trees in the forest are cut down
    2. Help to the trees to grow better
  3. Clear-felling
    1. Entire erea of the forest is eliminated
    2. Replanted or left unused to allow it to regenerate
    3. This can ocure to create land for crops or pastures
  4. Modern foresty
    1. Only mechanised and whith planned management
    2. Increases productivity
2. Factors
  1. Climate
  2. Soil
  3. Relief
  4. Wood
    1. Was used as fuel
    2. Use as financial profitability
      1. Furniture
      2. Papers
  5. Public awareness
    1. To evit soil erosion problems and deforestation
Fishing
1. types
  1. Commercial fishing
    1. Electrofishing whith suction
      1. A divice generate eklectrical discharge in the water to direct the fish toward the fish boat
    2. Deep-sea fishing
      1. Exclusively in open sea
      2. Very large ship and speand month fishing on the sea
  2. Aquaculture
    1. Harpoons
      1. They fish the fish whith the arpoon like an arc
    2. Fish pot
      1. Bzits is inside to attract the catch, once the thr prey entre in the pot, it cannot get out.
