V1 Flashcards
Bevölkerungswachstum:
- Der Mensch ist der dominierende ökologische Faktor
Changes in global parameters by humans:
Human environmental impact:
Loss in habitats:
Hunting (historical):
Overexploitation:
Further mechanisms for loss in biodiversity:
- climate change
- invasive species
- change in the N-cycle
- water use
The concept of ecosystem services:
- • Ecosystem services (ES) are contributions of ecosystem structure and function (in combination with other inputs) to human well-being
Classification of ecosystem services:
Examples of ecosystem services:
⇒ ESS = interface between people and nature
The Ecosystem Service Cascade (Cascade Model):
⇒ pathway of causal interrelations between ecosystem at one end and human well-being at another
The Ecosystem Service Cascade:
The Ecosystem Service Cascade:
The Ecosystem Service Cascade:
Assessment of ecosystem services:
Impact of management practice:
⇒ trade-off analysis
Relation of ecosystem services and biodiversity:
The Climate System:
The role of vegetation in the Earth‘s climate system:
- Example: feedback in the global carbon cycle
The role of vegetation in the Earth‘s climate system:
- Example: feedback in the energy and water cycle
Vegetation and climate interactions:
- green spaces as cooling areas: ∆T responsible for air exchange
- impact on formation of clouds and precipitation, water balance
- by photosynthesis, convection, turbulence: responsible for gas exchange
⇒ crucial term: quantity and quality of energy fluxes
