Lecture Notes: Urban Planning and Climate Change

Introduction

• Cities are a focal point for climate action.
• Urban systems contribute significantly to climate change.
• Better urban planning, such as renewable energy and afforestation, can have a substantial impact on climate change.
• Cities are the first point of response to climate activities.

Challenges of Climate Change

• Extreme Weather:
  • Increased erratic weather events.
  • Air quality has deteriorated despite past progress.
• Monsoons:
  • Decreased in duration from 120 to 72-75 days.
  • Increased total volume of rainfall, posing flooding risks.
• Flooding:
  • Changing rainfall patterns and inadequate infrastructure lead to flooding and loss of life.

Immediate and Long-Term Strategies

• Urban Planning Innovations:
  • Mapping shade in cities and planting new trees.
  • Light paving of streets to reduce temperatures.
  • Creating percolation ponds to improve water table levels.
• Infrastructure Development:
  • Building storm drains and dredging water bodies to reduce flooding.
  • Greening open spaces to enhance air quality.

Waste Management and Renewable Energy

• Waste Management:
  • Burning waste is a major emissions source.
  • Promoting recycling and reusing waste to halve landfill waste by 2030.
• Renewable Energy Initiatives:
  • Encouraging companies to adopt solar energy.
  • Target of 25% clean energy by 2025.
  • Solarizing highways and floating solar panels in lakes to generate clean energy.

Urban and Environmental Transformation

• Urban Forests and Parks:
  • Initiatives for more urban forests and better public transit.
  • Transition from car-dependent cities to transit-oriented cities.
• Renewable Energy Projects:
  • Decommissioning gas plants.
  • Developing large solar projects.
• Water Management:
  • Recycling wastewater to reduce emissions and electricity use.

Conclusion

• Transforming cities to improve quality of life and environmental standards.
• Demonstrating that urban areas can be innovative and maintain great living conditions while becoming environmentally friendly.
