- Q1
Which of the following is a type of water mining?
Well-and-pump technology to reach aquifers
Construction of large dams to store water for future use
Diversion of rivers & streams for agricultural irrigation
Water control land reclamation used in the Netherlands
Channeling water from subsurface springs to irrigate terraced fields
120s - Q2
Which of the following is a likely outcome of increased use of synthetic fertilizers on agricultural land?
There will be a decrease in greenhouse gas emissions in the farm’s immediate vicinity.
There will be an increase in dissolved mineral salts, making the soil too saline for crops to grow.
There will be a decrease in the use of pesticides because synthetic fertilizers help to reduce the number of pests attacking the crops.
There will be an increase in algae blooms in bodies of water as a result of nutrient runoff from fields.
There will be extensive erosion and an increase in desertification as a result of the high volume of manure created in CAFO facilities.
300s - Q3
Which of the following describes a goal of conserva-tion agriculture for African subsistence farmers?
The government will provide each farmer with at least two oxen to cultivate the fields.
Women in the villages will work together to clear the fields of dried stalks and leaves from previous crops before planting the new crop.
Irrigation ditches will be dug from nearby streams to provide constant water to the crops.
Monocropping will be encouraged, with each farmer exchanging produce with other farmers.
Farmers will practice species diversification by planting several different crops in each garden.
300s - Q4
Which of the following local activities can have a global impact?
Construction of a dam on the Columbia River to divert water from Washington to Oregon
Terracing the slope of the mountains in the valley of the Hong River by the Hani people of China
Burning parts of the Brazilian rain forest by pioneer subsistence farmers and ranchers to clear land for crops and cattle
Seasonal movements of pastoralist families in Mongolia and Norway
Cultivation of corn in Colorado to sell in U.S. states where corn is a primary export product
300s - Q5
Which of the following compares the regional production of biofuels?
Corn is the primary source of ethanol in Brazil, while wheat is the primary source in the United States.
Biofuels are produced only in the United States because only corn can be used.
Brazil produces twice as much ethanol per acre as the United States by using fermented sugar-cane instead of fermented corn.
Biodiesel is fuel made from olive oil and is produced in California and Italy.
Farms that produce corn for ethanol are dispersed throughout the United States and Mexico.
300s - Q6
Which of the following agricultural practices has the most significant long-term environmental impact in tropical regions?
Clearing small patches of land to pasture dairy cows, which decreases water pollution from runoff
Building terraces on sloping land to grow rice, which destabilizes hillsides
Burning extensive areas of forested land to create pasture, which decreases biodiversity
Burning small areas of forested land for subsistence farming, which increases biodiversity
Moving livestock to higher pasture areas in the spring, which leads to soil degradation
300s - Q7

Deforestation
Desertification
Deindustrialization
Devolution
120s - Q8

Nepal
Peru
The Philippines
Niger
Greece
120s - Q9
Which of the following environmental problems is most associated with the African Sahel?
Desertification
Deforestation
Air pollution
Flooding
Water pollution
120s - Q10
Which of the following best explains how the expansion of feedlots for raising cattle has affected environmental sustainability in rural areas?
Concentrating large numbers of farm animals in small spaces has decreased the release of carbon dioxide in the atmosphere.
Runoff from animal waste has increased the pollution in local water supplies.
Feed grains have eliminated potentially harmful invasive plant species from farmland.
Land development has increased the available water supply for other farming practices.
Composted manure has introduced valuable nutrients into previously depleted soils.

120s - Q12
The clearing of tropical rain forest for agriculture frequently results in
long-term productive farmland
a shift to animal raising
an increase in the size of the ozone hole
better-managed commercial forests
large-scale immigration
120s - Q13
Which of the following social or environmental impacts is most directly related to the use of chemicals in agriculture?
A decline in insect-borne diseases and improved health at the global scale
A decrease in the price of agricultural products due to lower labor costs associated with applying chemicals over widespread areas in one application
An increase in the use of genetically modified crops
An increase in profits that is limited to farmers in developed countries
An increase in land and water pollution from agricultural runoff
