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?

• 1. 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.

• 1. 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.

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?

• 1. 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.

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

• 1. Metal plows and harvesting equipment

• 1. Irrigated farm fields

• 1. Seed hybrids and animal breeds

• Chemical fertilizers and pesticides

Which of the following best explains a neo-Malthusian perspective on the Green Revolution?

• The Green Revolution represents a jump in agricultural technology, but population will still grow faster than our ability to produce food will over the long run.

• 1. The Green Revolution solves the entire problem of feeding the planet, and Malthusian ideas are no longer relevant.

• Local food production is the key to long-term food production.

1. 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?

• 1. The elimination of poverty in India’s rural regions

• 1. The use of genetically modified seeds

• 1. The use of improved plant hybrids and agricultural chemicals

1. 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

• 1. 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

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

• East Asia

• Sub-Saharan Africa

• Central America

1. Dramatic increases in global grain production since 1950 have been made possible by

• 1. substantial increases in the amount of land under cultivation

• global warming

• 1. an increase in the urban workforce

Which of the following best explains why farmers would plant both strawberries and watermelons in the same field?

• 1. Limited farmland encourages intensive farming with intercropping to produce high yields.

• 1. Limited farmland encourages extensive farming with monocropping to produce high yields.

• 1. Unlimited farmland encourages extensive farming with intercropping to produce high yields.

Which of the following statements best describes the impact of improvements in transportation systems on agriculture?

• 1. Local markets have become more important for dairy farmers.

• Corporate farms have gained a greater advantage over family farms.

• Cuisines have become more regionalized.
