Ecological Goods & Services |
Benefits occurring from functions of ecosystems |
|
|
Natural Capital |
Natural resources of economic value that may be exploited including minerals, soils, air, water, & living organisms |
|
|
Natural Goods |
Derived from natural world, human security is dependent on |
|
|
Natural Resources |
Feature of natural ecosystems & species that are of economic value |
|
|
Ecological Services |
Functions occurring as a result of ecosystem interactions |
|
|
Goods & Services in SK |
-Agriculture -Forestry -Mining |
|
|
Mining in SK |
-Potash -Uranium -Diamond -Gold -Phosphate |
|
|
Ecological Impact of Mining |
-environmental destruction -loss of biodiversity -more sinkholes -soil & water contamination |
|
|
SK Crops |
-Pulse crops -Oilseeds -Cereals -Forage crops -ETC. |
|
|
Issues//Degradation: |
-Wind Erosion -Water Erosion -Salinity -Desertification |
|
|
+ More Degradation: |
-water logging -soil fertility decline -deforestation -forest degradation -soil pollution -soil destruction -urban & industrial encroachment -effects of war |
|
|
Solutions//Mitigation Practices: |
-Conservation tillage (leaves previous crop's residue) -Contour farming (prevents bad erosion) -Grassed waterways (prevent erosion, protect) -Shelterbelts (protect) -Reduce oil contamination with bacteria (break down chemicals & clean) -Phytoremediation (remove contaminants) -Excavation (soil remediation) -Controlled burns (fertility & nutrients in soil) |
|
|
Solutions//Large-small scale composting: |
-Composting toilets -Trench composting -Vermicomposting -Windrow composting (piling organic matter in long rows) -Anaerobic digestion (Micro-organisms break down material) -Mechanical biological treatment (processing facility mixes composting + anaerobic digestion) |
|
|
Soil-Climate-Vegetation Relationships & Productivity |
-Plants create soil from rock but also decompose into soil when they die -Plants need soil & nutrients in it to grow -CLIMATE INFLUENCES WHAT PLANTS GROW IN AN AREA -Climate also influences how much water is in soil & if it's frozen or not |
|
|
Limiting Factors for animals (biodiversity issues)//Limiting Factors: |
Density-Independent Factors: (factors affecting population regardless of size) -Natural disasters -Human impact -Weather, light, temperature, humidity, etc.
Density-Dependent Factors: (factors affecting population dependent on size) -Food & Space -Overcrowding -Competition -Predation |
|
|
Animals//Impact of Habitat Loss |
-Human activity alters habitat (alteration) or separates it into pieces (fragmentation); this lowers biotic potential & worsens biodiversity •Farming •Cutting down forests •Dams •Urbanization -Some species benefit but displace others -FRAGMENTATION & ALTERATION INFLUENCES: •Migration •Breeding sites •Feeding sites |
|
|
Biodiversity Limited Through: |
-Extinctions & species being at risk -Habitat alteration & fragmentation -Invasive species -Pollution -Over harvesting -Climate change
|
|
|
Photosynthesis is affected by: |
Light intensity Temperature Water Minerals |
