Quiz: "Scenario selection"
(Please write down your answers in a notebook or a white sheet and compare them with the answers enlisted at the end of this section.There can be one or several correct answers)
1.- Which one of the following is false?
a) Human demand is shown in the FOOD worksheet
b) Biodiversity is shown in the BIODIVERSITY worksheet, measured in "numbers of animals saved" indicators
c) Area by land cover is shown in the LAND worksheet, with various graphs highlighting different changes in land cover
d) Computed greenhouse gas emissions by sector is shown in the GHG worksheet
e) Water footprint is shown in the WATER worksheet.
2.- Which of the following is an effect of an increase in population variation?
a) An increase in human demand
b) An increase in livestock products and pasture
c) A decrease in average daily kilocalorie consumption per capita
d) a) and b)
e) All of the above
3.- With limited land, and a growing population, total demand for livestock products will tend to increase. This will, in turn, lead to an increase in pasture areas, probably increasing deforestation. In order to satisfy the demand for livestock, and avoid increasing deforestation, which scenarios could users select in the calculator?
a) Reduce meat consumption through dietary shifts (change scenario to "less meat consumption")
b) Reduce post-harvest loss (Select reduction in PostHarvestLoss_Scen)
c) Increase livestock productivity (change to High Growth)
d) Reduce population growth (Change Human Demand)
e) a), c) and d)
4.- Dietary shifts can have major implications on the demand for agricultural products. What are the main implications on the land cover if a country's average diet changes from one that is rich in animal-based proteins to another one that is rich in plant-based proteins?
a) The consumption of livestock products decreases, therefore less pasture land is needed
b) The consumption of plant-based proteins (e.g., nuts) increases, therefore more cropland is needed
c) A fat-rich diet will imply a higher activity of the population, which will mean they would eat more, and thus more land is needed for both crops and livestock
d) a) and b)
e) b) and c)
5.- Changing the expansion of protected areas by 2050 can have an effect on which of the following values in the Calculator:
a) Available land for crops
b) Available land for livestock
c) Agricultural trade balance
d) Deforestation rate
e) All of the above
Answers:
1.- b) Biodiversity is shown in the BIODIVERSITY worksheet, measured in "numbers of animals saved" indicators. Reason: The calculator uses a land-based indicator for biodiversity.
2.- d) Both a) An increase in human demand and b) An increase in livestock products and pasture. Reason: An increase in population does not necessarily lead to a change in diets.
3.- e) Three scenarios reduce demand for livestock: a) Reduce meat consumption through dietary shifts (change scenario to "less meat consumption"); c) Increase livestock productivity (change to High Growth), and d) Reduce population growth (Change Human Demand). Post harvest loss scenario does not lead to any change in livestock demand.
4.- d) Both a) The consumption of livestock products decreases, therefore less pasture land is needed and b) The consumption of plant-based proteins (e.g., nuts) increases, therefore more cropland is needed. Reason: The composition of diets and activity level of the population are two different scenarios in the calculator, they do not follow directly from each other.
5.- e) All of the above. Reason: Changing the expansion of protected areas by 2050 has an effect on available land for crops and livestock, which in turn could affect the agricultural trade balance or the deforestation rate.
