Test 1 Flashcards
Sustainability
sustainable development is development
that meets the needs of the present without
compromising the ability of future
generations to meet their own needs
Three Pillars of Sustainability
Social
Environmental
Economic
5 Facets of Social Sustainability
Social Equity
Diversity
Democratic
Security
QOL
What is a big sustainability need?
Clean Energy
Why does the definition of a forest vary?
Location and perspective
Forests Vary By What?
Latitude, temp, precipatation, soils, and human patterns
Total Area of Forests
Forest Extent
How many forests in the world
4 billion hectares that cover 30% of the world
Forest Definition
Land spanning more than 0.5 hectares with trees higher than 5 meters and canopy cover of more than 10 percent. Land is not used by humans.
How to quantify amount of forests
Remote sensing
Size of Ecosystems
Can be any size and scale
Ecosystem Services
Benefits people obtain from ecosystems
Value of Ecosystem
Human Wellbeing it provides
Study of how human social systems relate with ecological systems
Human Ecology
The ecosystem provides services to the social system by moving materials, energy and information to the social system to meet people’s needs.
Ecosystem Foods
meeting present needs without compromising the ability of future generations to meet their own needs.
Sustainable developments
Global Forest Goal #1
Reverse the loss of forest cover worldwide through sustainable forest management, including
protection, restoration, afforestation and reforestation, and increase efforts to prevent forest degradation and contribute to the global effort of addressing climate change.
Global Forest Goal #2
Enhance social, economic, and environmental benefits by improving the lives of forest dependent people.
Global Forest Goal #3
Increase area of protected forests worldwide
Global Forest Goal #4
Mobilize new financial resources to implement in forest management
Global Forest Goal #5
Promote governance frameworks to implement sustainable forest management
Global Forest Goal #6
Enhance cooperation, coordination, coherence and synergies on forest-related issues at all levels
Four Main Sustainability Objectives
eradicate poverty; heal the planet;
secure prosperity for all; and foster peace and
justice.
Current Forest Trends
- Deforestation
- World will not meet current plan to increase forest growth by 3%
- Forests cover 30% of land area
- Tropical area is most abundant
Succession
Alters forest composition and structure over time
Final Succession Stage
Vegetation in a biome called a climax community
How do forests make the air breathable?
Forest Photosynthesis produces oxygen
What is a key driver of photosynthesis
CO2
Light
What determines color on leaves
Amount of sun absorbed creating chlorophyll
What affects plant respiration
temp, growth stage, and type of plant
What happens if a forest exceeds respiration
Mass amount of carbon
Transpiration
when plants lose H2O due to evaporation
When Precipitation hits the canopy
interception
through fall
snow fall
Macronutrients
Micronutrients
Nutrients from non living to living environments
Biomes
Worlds major communities that are shared with regional climates
3 main biomes
Boreal
Temperate
Tropical
Which Biome currently has the most deforestation
Tropical
How much forest area has been lost
About 50% and 1.8 billion hectares
4 Ecosystem Types
Cultural
Supporting
Provisional
Regulating
How much freshwater from forests
2/3 of US fresh water is produced by forests
