  • Regulates climate
  • Provides ecosystem services (e.g., air and water purification)
  • Supports human well-being
• Threats:
  • Habitat destruction
  • Invasive species
  • Climate change
  • Pollution

Carbon Footprint

• Definition: The total amount of greenhouse gas emissions generated by human activities.
• Calculation methods:

  • Input-output analysis
  • Emission factors
• Reduction strategies:
  • Increase energy efficiency
  • Switch to renewable energy
  • Implement sustainable transportation
  • Reduce, reuse, recycle

Sustainable Development

• Sustainable development is about meeting the needs of the present without compromising the ability of future generations to meet their own needs.
• It is built on three pillars: economic development, social equity, and environmental protection.

Key Principles of Sustainable Development

• Intergenerational equity: ensuring that the current generation does not compromise the ability of future generations to meet their own needs.
• Intra-generational equity: ensuring that all people within the current generation have equal access to resources and opportunities.
• Precautionary principle: taking precautions to prevent potential harm to the environment and human health.
• Polluter pays principle: holding those responsible for environmental damage accountable for the costs of restoration.

Renewable Energy

• Renewable energy is energy generated from natural resources that can be replenished over time.
• Examples of renewable energy sources include solar, wind, hydro, geothermal, and biomass energy.
• Renewable energy reduces greenhouse gas emissions, diversifies energy portfolios, creates jobs, and stimulates the economy.

Climate Change Mitigation

• Climate change mitigation refers to efforts to reduce the magnitude of climate change.
• Strategies for climate change mitigation include reducing greenhouse gas emissions, increasing energy efficiency, promoting sustainable land use, and developing climate-resilient infrastructure.
• International agreements such as the Paris Agreement (2015) and Kyoto Protocol (1997) aim to mitigate climate change.

Ecosystem Conservation

• Ecosystem conservation is the preservation and protection of natural ecosystems.
• Ecosystems are important because they maintain biodiversity, regulate the climate, provide ecosystem services, and support human well-being.
• Threats to ecosystems include habitat destruction, invasive species, climate change, and pollution.

Carbon Footprint

• A carbon footprint is the total amount of greenhouse gas emissions generated by human activities.
• Carbon footprint can be calculated using life cycle assessment, input-output analysis, and emission factors.
• Reducing carbon footprint can be achieved by increasing energy efficiency, switching to renewable energy, implementing sustainable transportation, and reducing, reusing, and recycling.

Land Restoration

Drought Monitoring

• Drought monitoring is crucial for land restoration as it helps identify areas of water scarcity and enables early intervention to mitigate its effects.
• Remote sensing uses satellite imagery to monitor vegetation health and soil moisture.
• Ground-based measurements involve monitoring precipitation, soil moisture, and water table levels.
• Drought indices calculate the severity of drought based on factors such as precipitation, temperature, and evapotranspiration.

Water Harvesting

• Water harvesting collects and stores rainwater for later use, reducing the demand on groundwater and surface water sources.
• Techniques include roof catchment systems, land surface management, and pond and reservoir construction.
• Benefits include reducing water scarcity and improving water security, decreasing soil erosion, and increasing groundwater recharge.

Ecosystem Restoration

• Ecosystem restoration rehabilitates degraded or damaged ecosystems to their natural state.
• Goals include biodiversity conservation, ecosystem function, and human well-being.
• Strategies involve habitat restoration, species reintroduction, and invasive species management.

Afforestation

• Afforestation establishes a forest on land that was previously unforested or under-forested.
• Benefits include carbon sequestration, soil erosion control, and biodiversity conservation.
• Challenges include finding suitable land, climate and soil limitations, and conflicting land-use activities such as agriculture or urbanization.
