Study Notes
Ecological Footprint
- A measure of the land and water an individual, population, or activity requires to produce resources and process waste.
- Typically measured in biologically productive hectares (1 ha = 2.47 acres).
- Calculated by summing the land needed for:
- Food consumed
- Water used
- Energy used
- Clothing worn
- Housing and transportation
- Developed nations have larger footprints than developing nations.
Carbon Footprint
- A measure of greenhouse gas emissions (primarily CO2, but also methane and others) from activities.
- Factors affecting footprints:
- Increase: Affluence (wealth), larger houses, more travel, meat consumption, and more resource-intensive goods.
- Decrease: Renewable energy use, public transport, plant-based diets, reduced consumption/travel/energy use.
Sustainability
- Using resources without jeopardizing future generations' ability to do the same.
- Developed nations consume more resources than developing nations.
- Earth's population of 8 billion faces resource challenges.
- Developing nations experience faster population growth and consumption increases.
Sustainable Development
- Balancing human well-being and economic progress with resource management for future generations.
Maximum Sustainable Yield (MSY)
- The highest amount of a renewable resource that can be harvested without depleting it.
- Roughly half the carrying capacity.
- Maximizes resource harvest and population regeneration.
Environmental Indicators of Sustainability
- Measurements describing the environmental system's state/Earth.
- Key Indicators:
- Biodiversity (genetic, species, ecosystem): Higher biodiversity indicates healthier ecosystems.
- Food Production: Earth's ability to support agriculture (threatened by climate change, soil degradation, groundwater depletion). Increasing meat consumption strains this system.
- Global Surface Temperature and CO2 Concentration: Earth depends on narrow temperature ranges. Increased CO2 from deforestation and fossil fuel use is unsustainable.
- Human Population and Resource Depletion: Growing human populations lead to unsustainable resource use.
Integrated Pest Management (IPM)
- Uses various pest control methods for minimal environmental disruption and pesticide use.
- IPM methods include:
- Crop rotation (planting different crops to prevent pest adaptation/disease).
- Intercropping (growing different crops simultaneously to promote biological interactions).
- Biocontrol (introducing species to consume pests).
- IPM benefits: reduced harm to non-target species, humans, and water. However, IPM methods might be more time-consuming/costly.
Sustainable Agriculture
- Meets food and fiber needs whilst enhancing soil quality.
- Sustainable practices include:
- Soil conservation (prevention of erosion, increased nutrients).
- Minimizing non-renewable resources.
- Economic viability for farmers.
Modern Sustainable Farming Techniques
- Agroforestry: Planting vegetation as windbreaks.
- Strip cropping: Using different spacing/rooting characteristics to prevent erosion.
- Contour plowing: Plowing/harvesting alongside land contours.
- Terracing: Shaping sloping land into flat steps.
- Perennial plants: Plants that don't need replanting.
- No-till agriculture: No plowing between seasons.
- Green manure: Planting material for plowing.
- Limestone: Ground calcium carbonate as fertilizer.
Organic Agriculture
- Crop production without synthetic pesticides/fertilizers.
Aquaculture
- Increasing fish production without depleting fisheries.
- Methods: floating nets, coastal ponds, inland ponds, enclosed land structures.
- Benefits: high yield, small land/water requirements.
- Drawbacks: limited biodiversity, high density can cause pollution/diseases.
Sustainable Forestry
- Managing forests for wood production, clean water, maximum biodiversity, and carbon sequestration.
- Methods: selective cutting, avoiding habitat fragmentation, removing diseased trees, and prescribed burning (to reduce dead biomass buildup).
