Carrying capacity and cross breeding
caryring capacity definition
The maximum population an environment can sustain indefinitely with available resources
What is CYMMIT
CIMMYT is a cutting edge, non-profit, international organization dedicated to solving tomorrow's problems today.
Where are most chinampas located
What is the name of the model
Von Thunen model
definition of commodity chain
process of transforming raw materials into consumer goods
what determines carrying capacity
factors like food, water, space, and technology
what does vandana shiva argue about GMOs
Vandana Shiva argues that GMOs are less about food security and more about patenting seeds to establish corporate ownership over biological resources
what endangers the chinampas
the contamination in mexico
what does the Von Thunen model do
The Von Thünen Model explains how land is used around a central market (CBD) based on the best possible transportation and land value cost ratio
commodity dependance definition
When a country’s economy heavily relies on exporting a few raw materials
what does exceeding carrying capacity lead to
leads to resource depletion, environmental degradation, and population decline
What is monsanto
Monsanto was a major agricultural biotechnology company known for producing genetically modified crops
who developed the chinampas
Chinampas were developed in Tenochtitlan by the Aztecs to be able to grow food on the lake where the city was localized
what does the model predict
It predicts different agricultural activities forming rings around a city, with intensive and perishable farming (dairy, vegetables) closer to the CBD and extensive, less perishable farming (grains, livestock) farther
where is commodity dependance common in
Common in developing nations (ex: oil in Venezuela, cocoa in Ivory Coast)
what is cross breeding
Selective breeding of different plant or animal species/varieties to produce hybrids
What big company controls Monsanto currently
Bayer
What soil do they use
Soil for the chinampas is lake sediment, which soaks the water up like a sponge so they don’t need to water them frequently.
name 2 limitations of this model
Assumes a uniform landscape with equal soil quality
Doesn't account for modern transportation, refrigeration, or global trade
Ignores government policies and subsidies
How did neocolonialism affect the commodity dependence of new countries that where former colonies
When these colonies/settlement ultimately got their independence starting from the 19th century, their economy was fully reliant on the export of goods to core-states, making it nearly impossible to change their economic system
give an example of cross breeding
Hybrid corn resistant to pests and harsh climates
What is GMO corn
GMO (Genetically Modified Organism) corn is corn that has been genetically engineered to have specific traits that do not naturally occur in traditional corn.
How many acres of Chinampas are there still
Today, though about 5,000 acres of chinampas still exist
What example was used to compare the Von Thunen model to current day (specific city used as CBD)
U.S.A (New York)
all stages of the commodity chain
stages: Extraction → Production → Distribution → Consumption
