Study Notes
Sustainability and Environmental Degradation
- Ecological footprint measures human impact on the environment, while environmental degradation is the deterioration due to human activities.
- Sustainability involves managing natural resources to meet societal needs and maintaining the environment for future generations.
- Environmental degradation has three primary forms: land and soil degradation, water degradation, and atmospheric degradation.
Types of Environmental Degradation
-
Land and Soil Degradation
- Deterioration of the quality and productivity of land surfaces, soil, and ecosystems.
- Causes include:
- Deforestation
- Excessive use of fertilizers and pesticides
- Soil erosion
- Desertification
- Land pollution
-
Water Degradation
- Contamination or degradation of water bodies such as rivers, lakes, and groundwater.
- Causes include:
- Industrial and municipal waste discharge
- Agricultural runoff
- Oil spills
- Marine debris
- Plastic pollution
-
Atmospheric Degradation
- Presence of harmful substances in the air affecting its quality.
- Sources include:
- Fossil fuel combustion
- Industrial emissions
- Agricultural activities
Principles of Sustainability
-
Economic Sustainability
- Focuses on maintaining and improving long-term economic well-being.
-
Social Sustainability
- Emphasizes community engagement and decision-making, empowering marginalized groups.
-
Environmental Sustainability
- Aims to protect and restore ecosystems, ensuring their long-term health and functioning.
Ecological Footprint
- Calculates the amount of productive land and water needed for resource consumption and waste absorption, based on current technology.
- Used to estimate carrying capacity for humans and supports sustainable population growth.
- Average ecological footprint per person globally is approximately 2.3 hectares of biologically productive land and sea.
- Global Hectare (gha) measures ecological footprints and biocapacity of the Earth.
- To sustain the current global population and average resource use, about 1.3 Earths worth of resources would be required.
Biocapacity
- Refers to ecosystems' capacity to generate resources and absorb waste.
- Essential for assessing sustainability and determining resource availability for populations.
