Global Environmental Change Flashcards
Ecological footprint
The impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources
Plant Phenology
the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life
Mitigation
- reduction of drivers of environmental change
- C cycle perturbation
- N emissions
- Water use
- Biodiversity loss
Bioenergy
used as transportation fuel and to generate heat and electricity
main source of anthropogenic N
- agriculture
- industry (emission from chemical plants, waste etc.)
- transport (fossil Fuel and atmospheric N transformation)
Resistance adaptation
describes the ability of a system to buffer disturbance
Resilience adaptation
Describes the capacity of a system to return to its former state after perturbation
Adaptation
describes the process of changing organisation/functioning of a system
C cycle perturbation
- Carbon capture (and storage)
- bio-energy
- non C based energy supple
- Land use change
retrofitting diversity into agriculture
- increase crop diversity
- increase plant diversity in pasture systems
- reduce reliance on human-generated inputs
- Agroforestry
Adjust global E balance
- space mirrors
- cloud seeding/brightening
- surface albedo
Geoengineering
Adjust CO2 Concentration
