A farm which uses small inputs of capital and labor relative to its size is called:

• Intensive

• Commercial

• Extensive

• Subsistence

What is the likely impact, if any, of the growing human population on the availability of land for food production?

• It is hard to determine due to uncertain predictions about the human population growth.

• Land availability remains constant.

• Land availability increases.

• Land availability decreases.

Which of the following practices in industrialized terrestrial food production systems contributes the most to global climate change?

• Soil erosion leads to nutrient depletion of soil and therefore, less vegetation to fix carbon dioxide from the atmosphere in the process of photosynthesis.

• Monoculture use leads to a loss of biodiversity when crops are struck with disease.

• Mechanization increases fossil fuel use and emits gases such as carbon dioxide or methane.

• All of the answer alternatives.

Which one of the following terrestrial food production systems uses the highest amounts of fertilizers?

• Intensive beef production

• North American cereal farming

• Maasai tribal livestock cultivation

• Subsistence farming in South-East Asia

From the reasons below, which contributes most significantly to food being wasted in LDCs?

• Excessive range of choice in supermarkets leads to large amounts of food being wasted

• Food waste occurs due to lack of labelling.

• Food waste occurs due to inadequate storage and poor transport infrastructure between farms and the market.

• Food waste occurs due to food becoming contaminated with pesticides.

Which of the following is not a contributor to the global increase in the consumption of meat?

• Status value of buying and eating meat within some cultures.

• Decreased levels of cheap meat production.

• Population growth.

• Urbanization and improved infrastructure.

• High protein content of meat.

which of the following is a reason for people going hungry in some countries?

• Poor infrastructure that limits access and distribution to food

• Extreme weather events, such as drought or floods.

• Poverty that prevents people being able to afford food.

• War and associated displacement of people.

• All are correct

From the reasons below, which contributes most significantly to food being wasted in MDCs?

• Consumers buy more food than they need and end up throwing it away.

• Food waste occurs due to lack of labelling.

• Food waste occurs due to inadequate storage and poor transport infrastructure between farms and the market.

• Food waste occurs due to food becoming contaminated at the production stage.

Possible solutions to improving sustainability of food supplies are

• Multinationals and food corporations raise standards for supply farms

• Find more land to grow food and increase yields through intensive farming techniques

• Eating less meat

• Always grow foods locally to cut down on transport related CO2 emissions.

• Use monocultures - focus on planting one food.
