- Water Treatment: Methods like coagulation, sedimentation, and biological treatment are used to purify water for consumption and recreational use.
- Waste Management: Strategies for managing solid and hazardous waste, including recycling, composting, and incineration, are essential for reducing landfill use.
2. Resource Management
Resource management encompasses the sustainable use of natural resources, which includes:
- Water Resources: Efficient management of freshwater sources through techniques such as rainwater harvesting and wastewater recycling.
- Energy Resources: Development of renewable energy sources like solar, wind, and biomass to reduce dependence on fossil fuels.
- Land Use Planning: Strategies for sustainable land development that minimize environmental impact and preserve ecosystems.
3. Environmental Impact Assessment (EIA)
Environmental Impact Assessments are critical for evaluating the potential effects of proposed projects on the environment. The EIA process typically includes:
- Screening to determine whether an EIA is required.
- Scoping to identify key environmental issues and concerns.
- Impact analysis to assess how the project may affect the environment.
- Mitigation measures to minimize negative impacts.
- Reporting and public consultation to ensure transparency and community involvement.
