Why is the Netherlands a huge contributor to global deforestation?

Slide 13 - Mind map

  • The Netherlands is one of the largest European importers of soybeans
  • Farmers use soybeans to feed their cattle
  • Soybeans plantations are usually created in rainforest areas

Slide 14 - Slide

Slide 15 - Link

In The Netherlands we have:

  • More than 12 million pigs
  • More than 3,8 million cows
  • More than 100 000 000 million chickens


 

Slide 16 - Slide

How does the production of meat lead to deforestation of the tropical rainforest?
 

  • Production of 1 kilo of meat:  50 tot 250 m² is needed
  • More space is needed for the animals and for fields of animal feed 
  • Deforestation tropisch regenwoud 

Slide 17 - Slide

Tropical rainforest and agriculture: Amazon 

Slide 18 - Slide

Slide 19 - Slide

Food footprint increases
Food footprint = the space needed to produce the food for a single person

  • World population increases
  • World population is getting richer

A
The poorer, the bigger the meat consumption
B
The richer, the bigger the meat consumption
C
The bigger the population, the bigger the meat consumption
D
The smaller the population, the bigger the meat consumption

Slide 22 - Quiz

What is changing in the food industry?
Quite a lot: organic framing, large-scale framing and intensification.
Organic farming
Organic farming uses fewer pesticides and gives animals more space
Large-scale farming
Companies make a lot of the same food. This is the most efficient. 
Intensification
Companies that use knowledge and money for higher yields (opbrengsten). They use a lot of modern technology.

Slide 23 - Slide

Large-scale farming
Agricultural businesses that are
expanding and maximizing 
their production

Slide 24 - Slide


Large-scale farming
  • Larger farms, fewer types of crops (or 1 species = monoculture)
  • Advantage:  knowledge of 1 product and only 1 type of machine is needed
  • Disadvantage: decrease of biodiversity
Large-scale farming
This is easy for the farmers. 
They can harvest a lot at one time.
Without large-scale farming
Here grow many types of plants. This is good for the biodiversity, but the work for the farmer is more difficult and expensive.

Slide 25 - Slide

Intensification
An increased yield of crops per hectare or per animal by means of knowledge or capital

Slide 26 - Slide


Intensification
  • Farmers try to get as much as possible out of a piece of land or an animal.
  • Use of science and expensive machines.
Intensification

This farmer uses a drone
to determine exactly how much manure (mest) is needed
  
Intensification

All these cows are milked at once by one machine.
This saves the farmer a lot of work.
