The 20 questions

  1. A hot desert case study should include which element to address key themes of the specification?

    • A description of the desert with no reference to the processes that shape its landforms
    • A general overview that ignores the local setting and describes deserts in the abstract
    • A list of tourist attractions with no data on the environment or its landforms
    • Analysis of field data that illustrates processes and landforms in the chosen desert setting
  2. Which of these is a valid example of a human response to desertification?

    • Establishing shelter belts and sustainable grazing schemes to reduce erosion
    • Clearing shrubs to create more grazing land for livestock on the fragile dryland slopes
    • Ploughing steep slopes annually for cropping, which exposes the soil to wind and rain
    • Expanding irrigation from a fossil aquifer without any limit on how much water is extracted
  3. In a local desertification case study, which combination best describes an appropriate evaluation of human responses?

    • Judgement of the desert's beauty without evidence, based on the impressions of visitors
    • Assessment of resilience, mitigation and adaptation strategies and their effectiveness for local people
    • Comparison of the desert with a distant tropical forest only, which does not address the local responses
    • Assessment of tourist numbers only, which indicates how many visitors use the area each year
  4. Which feature of a local desertification case study would most strongly support sustainable development implications?

    • Evidence that population has fallen to zero, so that there are no longer any local livelihoods
    • Evidence that land degradation is increasing with no change in management or in the local economy
    • Evidence that restoration reduces degradation while maintaining livelihoods
    • Evidence that the desert has no residents, which means that its management has no social effect
  5. Which approach would be most useful for a field study in a hot desert setting that cannot be conducted in a true desert?

    • Using an analogous setting such as coastal dunes that experience similar aeolian processes
    • Using a tropical forest with no dune processes at all, which offers a different set of landforms
    • Using an urban park with no landforms of aeolian origin, which lacks the relevant processes
    • Using a river delta that has no aeolian processes, which offers only fluvial and marine features
  6. When evaluating a desertification case study, which weakness should be acknowledged?

    • Desertification never involves any human activity, so the human dimension can be ignored entirely
    • Desertification always reverses within a year, so long-term data are not needed to assess it
    • Limited long-term data may make it hard to separate climate effects from human impacts
    • Desertification is always caused by a single identical factor everywhere, so no other cause needs to be considered
  7. Which element of a desertification case study would best illustrate the impact on populations?

    • Evidence of changes in livelihoods, food production and water access over time
    • Information on the desert's distance from the equator alone, which gives the latitude but no impacts
    • A description of the desert's wind direction only, which does not show the social effects
    • A list of the desert's rock types, which describes the geology but not the people who live there
  8. A case study proposes a water harvesting scheme in a dryland village. What is the most important evidence for judging its success?

    • The number of visitors who photograph the scheme and share the images on social media
    • The colour of the water tanks used in the scheme, which indicates how well they are maintained
    • Monitoring of water availability and crop yields before and after the scheme
    • The cost of the tanks compared with the price of a single car, which measures the local value
  9. Which response to desertification is best described as adaptation rather than mitigation?

    • Reducing grazing pressure to halt land degradation, which addresses the cause of the problem directly
    • Changing crop varieties and planting schedules to suit reduced rainfall
    • Planting trees to stabilise sand dunes, which reduces the erosion that is causing the degradation
    • Restoring vegetation to reduce wind erosion, which tackles the process of land loss itself
  10. Which statement evaluates a desert case study fairly?

    • The response has failed completely with no benefits for the land or the local population
    • The response has been a complete success with no limitations or costs for any of the people involved
    • The response has delivered some benefits but its long-term effectiveness depends on maintaining management and funding
    • The response is irrelevant because deserts cannot be managed in any practical or useful way
  11. Which question would best guide a fieldwork plan for a desertification case study?

    • What is the most attractive colour for a field notebook, so that the team can find it easily on site
    • What evidence will show whether vegetation cover and soil condition have changed over the study period?
    • Which local restaurant serves the best food, so that the team can plan its meals during fieldwork
    • How many kilometres is it from the nearest airport to the case study site in total distance
  12. Which contrast would be most valuable in a hot desert case study?

    • Two deserts with identical land use and identical degradation, which would show no contrast at all
    • Land managed sustainably compared with nearby degraded land under similar rainfall
    • A desert and a polar ice sheet with no shared processes, which cannot be meaningfully compared
    • A desert and an urban area that has no vegetation, so that the comparison has no ecological value
  13. A case study finds that a community's income has risen after land restoration. Which conclusion is most secure?

    • Income is unrelated to land condition in any setting, so the restoration cannot have had an effect
    • Restoration always reduces income in drylands, so the rise must have come from elsewhere entirely
    • The restoration alone caused the income rise, with no other factors involved in the local economy
    • The restoration may have contributed to income rise, but other economic factors should also be considered
  14. Which element should a hot desert case study include to show a response to desertification?

    • A list of tourist attractions with no environmental information about the desert
    • A set of photographs with no analysis of processes or of the responses to them
    • An evaluation of resilience, mitigation and adaptation with evidence from the local area
    • A description of the desert's climate with no reference to the people who live there
  15. Why is a case study of a local desertification site valuable?

    • It compares the desert with an ocean using identical data sets for the two environments
    • It provides a single figure for the global area of deserts, which can be used in all studies
    • It describes the history of the desert's name and early exploration by travellers
    • It links field evidence of degradation to causes, impacts and the management responses of local people
  16. Which statement about a case study of an analogous coastal dune setting is most accurate?

    • It replaces the need for any field data because all dunes are identical in their behaviour
    • It can only be used if the coastal dunes have exactly the same climate as a hot desert
    • It can illustrate aeolian processes where a hot desert itself is difficult to study in the field
    • It shows that aeolian processes do not occur outside hot desert regions of the world
  17. A case study reports that a community has adopted drought-resistant crops. Which evaluation criterion is most relevant?

    • Whether the crops have a bright colour that attracts visitors to the village market
    • Whether the crops were grown on land owned by the local council only
    • Whether food security and income improved over the period of the study
    • Whether the seed packets are easy to store in the village during the dry season
  18. Which weakness is most likely in a desertification case study based on a single site visit?

    • The findings will always apply to all deserts, since the site is typical of every region
    • The findings may not be representative of other drylands or of changes over time
    • The findings are always more reliable than data from several sites over a longer period
    • The findings cannot be affected by the time of year of the visit, which is irrelevant
  19. What does resilience mean in a desertification case study?

    • The amount of rainfall needed to cover the land with a green crop in a single season
    • The capacity of a community or ecosystem to absorb, recover from or adapt to degradation or drought
    • The ability of a desert to remain completely unchanged by any human activity over the centuries
    • The speed at which dunes migrate across a desert surface each year during the strong winds
  20. Which example would best illustrate mitigation in a desertification case study?

    • Building a higher wall around the village to keep out the wind-blown sand
    • Fencing and resting degraded grazing land so that vegetation can recover
    • Buying imported food when local harvests fail during a drought year
    • Moving livestock to a new site after the grazing land has already been destroyed
