The 20 questions

  1. What process occurs when excessive irrigation leads to salt accumulation in surface soil?

    • Eutrophication
    • Desertification
    • Salinisation
    • Acidification

  2. Which environmental issue is caused by the runoff of nitrogen and phosphorus fertilisers into waterways?

    • Eutrophication
    • Desertification
    • Bioaccumulation
    • Salinisation

  3. What term describes the increasing concentration of toxic chemicals in organisms up a food chain?

    • Carbonation

  6. What long-term impact on biodiversity occurs when primary forests are cleared for commercial cattle ranching?

    • Salinisation
    • Eutrophication
    • Soil compaction

  7. Which group's traditional food security is often threatened by commercial agricultural expansion into remote ecosystems?

    • Agribusiness executives
    • Urban consumers
    • Transnational corporations
    • Indigenous populations

  8. Which type of agricultural chemical is primarily responsible for nitrate contamination in groundwater supplies?

    • Biological herbicides
    • Chemical fungicides
    • Organophosphate pesticides
    • Synthetic fertilisers

  9. A farmer over-irrigates arid cropland, leading to high evaporation and white surface crusts. What is this?

    • Soil salinisation
    • Nutrient leaching
    • Groundwater recharge
    • Soil erosion

  10. An agricultural region suffers from widespread algal blooms and dead zones in adjacent lakes. What caused this?

    • Soil salinisation
    • Pesticide drift
    • Agrochemical runoff
    • Overgrazing

  11. Long-term exposure to organophosphate pesticides among farmworkers is most directly linked to which health impact?

    • Marasmus
    • Type 2 diabetes
    • Neurological damage
    • Kwashiorkor

  12. Converting species-rich tropical rainforest into monoculture oil palm plantations causes which immediate ecological change?

    • Biodiversity loss
    • Groundwater rise
    • Nutrient enrichment
    • Soil salinisation

  13. A population experiences stunting and wasting due to prolonged failure to access sufficient calories. What is this?

    • Food surplus
    • Nutrient toxicity
    • Chronic hunger
    • Obesity

  14. Intensive groundwater extraction for crop irrigation in coastal agricultural zones often leads to which specific hazard?

    • Eutrophication
    • Saline intrusion
    • Siltation
    • Soil erosion

  15. High levels of nitrates in drinking water from agricultural runoff can cause which infant health condition?

    • Blue baby syndrome

  16. Which short-term physical environment impact occurs immediately following heavy rain on bare, freshly ploughed fields?

    • Salinisation
    • Desertification
    • Aquifer depletion
    • Topsoil erosion

  17. How does intensive monoculture crop production primarily reduce long-term agricultural landscape resilience?

    • Reducing pesticide reliance
    • Depleting soil nutrients
    • Increasing biodiversity
    • Lowering water usage

  18. Why does heavy pesticide application over long periods often lead to increased pesticide use later?

    • Pest resistance development
    • Increased soil salinity
    • Decreased runoff rates
    • Enhanced crop immunity

  19. What is the primary cause of soil pan formation under heavy agricultural machinery?

    • Eutrophication
    • Soil compaction
    • Salinisation
    • Leaching

  20. In high-income countries, food surplus combined with low-cost ultra-processed foods most directly drives which public health crisis?

    • Micronutrient deficiency
    • Obesity epidemics
    • Infectious disease
    • Malnutrition stunting
