Green Revolution

The domestication of plants and animals occurred in the

• First Agricultural Revolution

• Green Revolution

• Second Agricultural Revolution

• Columbian Exchange

• Industrial Revolution

Deforestation has resulted in

• more farmland in some places but more desertification in others

• more farmland in some places and less desertification in others

• less farmland in some places but more desertification in others

• less farmland in some place and less desertification in others

• no noticeable change in the amount of farmland or desertification

Which statement about 1961 to 2011 is best supported by the graph?

• Food scarcity improved in both Asia and Africa

• Green Revolution techniques worked better in Asia than in Africa

• Population growth was higher in Africa than in Asia

• Green Revolution techniques worked well in both regions but slowed down dramatically

• Millet and rice are not very important food sources for either region, indicating that a conclusion about food security is invalid

Southwest Asia, Southeast Asia, East Asia, Mesoamerica, and the Sub-Saharan regions were all

• leaders in starting the Columbian Exchange

• sites where the Second Agricultural Revolution began

• areas noted for widespread terracing

• hearths of plant domestication

• regions where the Third Agricultural Revolution failed

Between 1950 and 1990, wheat production in India in average pounds per acre more than tripled, which allowed India to meet its population's need for food. Which of the following best explains this change?

• The elimination of poverty in India's rural regions

• The use of genetically modified seeds

• The increase of microloan programs that provide farmers with credit

• The use of large farm tractors and combine harvesters

• The use of improved plant hybrids and agricultural chemicals.

Which of the following agricultural inputs were the most recent technological innovations employed in less developed countries during the Green Revolution?

• Metal plows and harvesting equipment

• Irrigated farm fields

• Seed hybrids and animal breeds

• Chemical fertilizers and pesticides

• Terracing in highland terrain

In which of the following world regions has the Green Revolution had the least impact on agriculture?

• East Asia

• South Asia

• Southeast Asia

• Central America

• Sub-Saharan Africa

During the Green Revolution, agricultural practices from more developed countries diffused to less developed countries in Asia and Africa. Which of the following best explains the Green Revolution's highly variable level of success in increasing agricultural yields?

• The increased yield of the Green Revolution in sub-Saharan Africa decreased the incidence of famine, but the program was unsuccessful in India because of poor soil quality.

• Small-scale farmers in Asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the Green Revolution outside of urban cores.

• The Green Revolution was not successful in China because the strain of rice produced was prone to widespread crop failures, and China dropped out of the program.

• Rice production surpassed all other crop production in sub-Saharan Africa, but corn production in Mexico was less successful because of the negative impact on the environment.

• Persistent famine has occurred in India since new technologies associated with the Green Revolution were implemented because only the wealthy could afford the increased cost of the improved strains of rice.

Green Revolution technology has resulted in which of the following in modern

agriculture?

• The development of high-yield grains and the expansion of cultivated areas

• The construction of new irrigation systems and a reduction in the use of fertilizers

• An increase in the circulation of investment capital to help the poorest farmers

• The loss of prime agricultural land and smaller yields from grain crops

• The end of famine in the world

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?

• Crop dusters are at risk when applying pesticides with aircraft in more developed countries, whereas environmental pollution is a risk in less developed countries.

• Farm animals used to plow fields are at risk from pesticides in more developed countries, whereas environmental pollution is a risk is less developed countries.

• Farmers' health is at risk in less developed countries, whereas environmental pollution is a risk in more developed countries.

• Crops are at risk in more developed countries, whereas environmental pollution is a risk in less developed countries.

• Contract harvesters are at risk in more developed countries, whereas environmental pollution is a risk in less developed countries.
