Land & Water Use
In evaluating food security under scenarios of climate change, which aspect associated with the outcomes of the Green Revolution may be most at risk?
Reduced reliance on synthetic fertilizers lowering pollution risks from runoff.
Greater emphasis on traditional agriculture practices improving soil health over time.
Increased genetic diversity within major food crops enhancing resilience.
Reliance on monoculture cropping systems vulnerable to extreme weather events.
How did the introduction of synthetic fertilizers during the Green Revolution primarily affect energy transfer in agricultural ecosystems?
Reduced soil erosion by increasing organic matter in the soil.
Increased primary productivity due to enhanced nutrient availability.
Decreased algal blooms due to more efficient use of nutrients.
Lowered primary productivity because of chemical toxicity to plants.
Which crop has seen significant yield increases due to Green Revolution technologies?
Cassava
Wheat
Blueberries
Quinoa
How could climate change potentially undermine the gains made by the Green Revolution in crop yields?
Through decreased carbon dioxide levels limiting photosynthesis rates in plants.
By altering rainfall patterns and increasing droughts that reduce water available for crops.
By reducing the occurrence of plant diseases that affect large monocultures.
By decreasing global temperatures leading to lower evaporation rates from soil.
What impact did mechanization have on farms during the Green Revolution?
Hand tools became more prevalent than machines on large farms
It allowed for faster cultivation and harvest times
Farm sizes decreased as less land was needed for machinery
Farmers relied less on nonrenewable energy sources
Which practice linked to the Green Revolution poses the greatest risk for contributing to climate change?
Amplified carbon sequestration via widespread adoption of cover cropping techniques.
Reduction of greenhouse gases due to lessened dependence on deforestation and agricultural expansion.
Increased methane emissions from intensively managed rice paddies.
Lowering energy consumption through enhanced efficiency of mechanized equipment.
Which of these agricultural practices developed during the Green Revolution is most susceptible to the impacts of climate change due to its high dependence on predictable water availability?
Organic farming
Integrated pest management
Crop rotation
Intensive irrigation

Which of the following best describes a potential negative consequence of the Green Revolution on biodiversity?
Decreased genetic diversity in crops due to reliance on monocultures.
Reduction in soil erosion due to advanced planting techniques.
Increased use of land for habitat conservation as crop yields improve.
Enhanced ecosystem resilience through the introduction of various new species.
What is one environmental impact commonly associated with Green Revolution agriculture practices?
Increased pesticide use
Reduced soil erosion
Fossil fuel consumption decrease
Improved grasslands habitat
How might synthetic fertilizer use during the Green Revolution affect nitrogen cycling within an agricultural ecosystem long-term?
Steady decrease in nutrient depletion allowing prolonged agricultural productivity without additional inputs.
Improved efficiency in nitrogen uptake by plants reducing leaching into groundwater supplies significantly.
Gradual replenishment of natural nitrogen fixers increasing biodiversity in farming communities.
Disruption of nitrogen balance leading to increased nitrate runoff into adjacent waterways.
