Define the term "Green Revolution" as used from 1945 to the present
|
Green Revolution was a movement in the 1940s that aimed at the use of new technologies in agriculture.
|
|
|
Explain TWO principal agricultural practices/technologies associated with the green revolution
|
Fertilizer- chemical use in fertilizer made crops grow bigger and faster
Miracle Seeds- like Monsanto soy beans that are genetic copies of a previous seed that seemed to grow quite well |
|
|
Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields
|
India and Southeast Asia
|
|
|
Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution
|
Education-need to be knowledgeable about new technologies; Money-required in order to buy new equipment
|
|
|
Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution
|
Water Pollution- doesn’t pay attention to the use of fertilizers and hurts the aqua-environment; Poor Economy- if people don’t have enough money to pay for upgrades then they won’t be able to get them

|
List TWO factors that have increased the demand on poultry
|
Population Growth; health benefits; availability
|
|
|
Briefly describe TWO characteristic of the economic organization of poultry in the united States
|
Large scale operations; a large industry controls most of the steps in the process of poultry
|
|
|
Describe TWO features of the present geographic distribution of poultry production in the Unites States
|
Regional concentration in poor farming areas; transportation to market or economic corridors
|
|
|
Applying the underlying principles of von Thunen's model of agricultural land-use to predict the activities shown in X and Y relative to a large urban area
|
X- closer to the market; Y-further away from the market
|
|
|
Choose either X and Y and apply the underlying principles of von Thunen's model to explain the location of the activity
|
X- intensive agriculture, higher value land, fresh produce, closer to market to enhance max profit to farmer
|
|
|
Discuss two factors that explain why agricultural land-use patterns today differ from those developed by von Thunen's model in 1826
|
Now we can refrigeration and our food supply is greater, also there is improved transportation
|
|
|
For Von Thunen and Burgess' model identify the type of land use the model addresses
|
Thünen’s model- rural, agricultural areas; Burgess’ model- urban and city areas
|
|
|
Identify two assumptions that are shared by moth models
|
There is only one market; there is a flat, featureless area
|
|
|
For each model, explain how relative location affects land-use patterns
|
Thünen. Effect-intensive land use near market to achieve high profits to pay rent; Burgess. Effect- the high social economic class located at the edge of the city because they have more money for large acreage and bigger homes.
|
|
|
Identify and then explain two factors contributing to the steady decline in the number of dairy farmers
|
Increased production of milk- cows make more milk, meaning fewer cows; increased mechanization-increases the size of dairy herds
|
|
|
identify and explain two factors contributing to the increase in the number of organic farms
|
Increased demand- healthier for you, more appealing; Better care for the land-sustainable agriculture
|
|
|
Identify and Explain two reasons why some geographers today believe that Malthus' theory can be used to predict future population issues
|
Population is growing- limited use of contraceptives, cultural or political decisions that encourage population growth; Food Supply has grown but not kept up with population growth- changing farmland into urban areas, not adapting to new agricultural techniques
|
|
|
Identify and explain TWO reasons why some geographers today believe Malthus' theory cannot be used to predict future population issues
|
2. Population is not growing exponentially- use of contraception in more countries; Food Supply has grown faster than Malthus predicted- Green Revolution, expansion of agricultural land
|
