Unit 5 APHG
Subsistence agriculture is most common in which of the following regions?
Amazon Basin
which of the following agricultural practices has the most significant long term environmental impact in tropical regions?
Burning extensive areas of forested land to create pasture, which decreases biodiversity
Which of the following explains the role of commodity chains in the average size of farms?
Commodity chains have led to changes in the spatial organization of agriculture from dispersed family farms to large corporate farms that produce, process, and distribute the products.
Which of the following best explains the economic advantage of the type of farm produced goods shown in the images?
Compared to plain milk or fresh fruit, these value-added agricultural goods significantly increase the price of the farm products sold and increase earnings for farmers.
Discuss two factors that explain why agricultural land-use patterns today differ from those developed by von Thünen's model in 1826.
One factor would be that we now have increased transportation and that means that the rings would be much wider as we can transport perishable goods and livestock to wherever is necessary. Another factor is that technology has advanced so that we are able to produce more products in a much smaller amount of space, therefore we have more space for other types of farming or specific crops.
What are farm subsidies?
Payments made to farmers for not growing certain crops so that prices will be higher.
The second agricultural revolution coincided with...
Industrial Revolution
Describe the change over time in the numbers and sizes of family-run dairy farms.
Family-run dairy farms decreased in number as more dairy products are being produced by large corporate farms (e.g., agribusinesses) instead of family-run farms.
Three of the largest dairy regions in the United States are in the Northeast (New York and Pennsylvania), the Upper Midwest (Wisconsin and Minnesota), and California. What explains this phenomenon?
Large urban centers are located in each zone

Why have many family farms in North America been replaced by agribusiness farms since the 1980s?
Agribusiness farms have the resources to take advantage of economies of scale.
Define intensive agriculture.
Agriculture that requires large quantities of inputs (e.g. labor, capital, agricultural products) per unit of land.
Explain a negative affect the irrigation may have a water quality
Areas drenched by irrigation can become waterlogged, creating soil conditions that poison plant roots. where water has been diverted soil can intake too much salt also harming plant growth.
Explain why large scale commercial agricultural operations are increasingly replacing small family farms in developed countries
As large scale commercial farms are able to produce crops and livestock at a lower cost due to the economies of scale. They can often sell their products at a lower price that smaller family run farms.
What is the best reason why market gardening farms are located close to urban centers?
Because it is expensive to transport and they go bad quickly.
Which of the following best explains the diffusion of plants and animals from their hearths of domestication?
Both domesticated plants and animals spread across the globe through contagious diffusion in early years by farmers and traders, and later by relocation diffusion through European exploration and colonialism.
Which of the following best explains the reasons for the similarities and differences between the two land survey systems shown?
Both systems require geometric calculations to survey property lines. However, the township-and-range system uses simplified calculation to create a more ordered landscape.

Costs of labor, transport, and land rent
Explain a recent trend in the location of dairy farms with respect to consumer locations.
Dairies have moved farther from consumer locations as a result of improvements in transportation methods and networks
Explain how economies of scale are used to maximize profitability in dairy farming.
Dairy farms can reduce per unit costs by manufacturing larger volumes of milk or dairy products using mechanization, transportation, or computerized production processes that reduce the amount of labor or energy needed to produce each unit of food
Explain an environmental sustainability problem that results from the production of dairy on large-scale farms.
Degradation of ecosystems (e.g. deforestation, overgrazing) has occurred in order to increase the size of or production levels on dairy farms.

Which of the following explains why multiple early hearths of domestication and diffusion of plants and animals arose across the world in Central America, the Fertile Crescent, the Indus River valley, and Southeast Asia?
Domestication of plants and animals evolved in each hearth independently of one another as societies in each area learned and applied the process to local plants and animals.
which of the following explains an impact of globalized agricultural commodity chains on consumers as compared to producers?
Drought and depletion of groundwater sources in developing countries cause a rise in global grain prices and associated higher costs for food.
In less developed countries, pesticides are typically applied by hand, whereas pesticides are typically applied by tractors or aircraft in more developed countries. Which of the following best explains the risks associated with pesticide applications?

Explain ONE way in which a complex commodity chain connects large-scale dairies to consumers.
Milk is manufactured into value-added dairy products (e.g. yogurt, cheese, cream, other dairy products, frozen foods), increasing the complexity of the commodity chain as more steps are needed for processing and packaging.

The entire country is their market area for these products.
Apply the underlying principles of von Thünen's agricultural land-use model to predict the locations of the activities shown in X and Y relative to a large urban area.
The location of model X would be in the smallest (first) ring. Model X would be closest to the city because it is very perishable. The location of model Y would be in the third ring. Model Y would be a bit farther from the city but not the farthest because it needs a lot of room for growing crops but not as much as grazing livestock.
The two images show different agricultural methods. In the context of the Second Agricultural Revolution, which of the following trends is represented in these images?
The mechanization of farming in the Second Agricultural Revolution resulted in more reliable crop harvests and healthier populations in areas where the mechanization was adopted.
based on the physical characteristics of the landscape shown in image two, explain why people adopted the practice shown in the image
The physical characteristics of the landscape include elevation differences. Based on this, the practice of terrace farming was adapted to maximize agricultural productivity. So the irrigated terraces may have been used to combat that, and increase the amount of food that can be produced. -Ex. Southeast Asia
The two images represent different agricultural land survey patterns. Comparing the two images, which survey system was more efficient in terms of trade?
The river in the long lot survey system provided better access to waterways to transport goods to market.

The use of improved plant hybrids and agricultural chemicals
Even though climatic conditions are suitable for wine production in North Africa and Southwest Asia, why is this form of agriculture not practiced in these regions?
There is not a cultural tradition of consuming wine in these regions.
Based on the map, which of the following explains the similarities of the world regions where at least 51 percent of women work in agriculture?
These regions are composed of less-developed countries with large rural populations.

Why did von Thunen include a forestry ring in his model of agricultural land use?
Wood was used for construction purposes and heating. Wood is heavy and therefore expensive to transport.

Choose either activity X or activity Y and apply the underlying principles of von Thünen's agricultural land-use model to explain the location of the activity.
X is closest to the city because fruits and vegetables are very perishable and wouldn't last if they were in any of the outer rings.
