The debate on growth versus environment at the urban scale – Nature

Report on the Growth versus Environment Debate at the Urban Scale

Introduction

The ongoing debate between economic growth and environmental sustainability has traditionally focused on national and global levels, often overlooking the critical role of cities. Given the increasing concentration of populations, economic activities, and emissions in urban areas, this report examines how the growth-versus-environment discourse applies specifically to cities, with a strong emphasis on the United Nations Sustainable Development Goals (SDGs).

Urban Growth Dimensions and Sustainability

This report identifies four key dimensions of urban growth:

1. Economic Growth
2. Population Growth
3. Spatial Growth
4. Environmental Impact

These dimensions are analyzed in relation to three prominent narratives:

• Green Growth: Advocates for sustainable economic development that decouples growth from environmental degradation, aligning with SDG 8 (Decent Work and Economic Growth) and SDG 11 (Sustainable Cities and Communities).
• Degrowth: Calls for a reduction in economic activity to achieve ecological sustainability, supporting SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action).
• Post-Growth: Envisions alternatives beyond traditional economic growth models, emphasizing social well-being and environmental limits, relevant to SDG 3 (Good Health and Well-being) and SDG 10 (Reduced Inequalities).

Key Issues in Urban Growth and Environmental Policy

Horizontal Spillovers Among Cities

Urban areas influence each other through economic, social, and environmental interactions. Understanding these spillovers is essential for coordinated policy-making that supports SDG 17 (Partnerships for the Goals).

Vertical Policy Integration

Effective environmental policies require integration across local, regional, and national levels to ensure coherence and maximize impact, advancing SDG 16 (Peace, Justice, and Strong Institutions).

Local Experiments and Innovations

Urban experiments in sustainability, such as pilot projects and innovative governance models, provide valuable insights for scaling solutions that contribute to multiple SDGs, including SDG 7 (Affordable and Clean Energy) and SDG 9 (Industry, Innovation, and Infrastructure).

Connecting the Growth Debate to Urban Environmental Policy

This report synthesizes theoretical and empirical evidence to bridge the abstract growth-versus-environment debate with practical urban environmental policies. The findings underscore the importance of aligning urban development strategies with the SDGs to achieve sustainable, inclusive, and resilient cities.

Recommendations for Policy and Practice

• Promote green growth strategies that foster economic development while reducing environmental footprints, supporting SDG 8 and SDG 11.
• Incorporate degrowth principles where appropriate to address ecological limits and social equity, aligned with SDG 12 and SDG 13.
• Encourage post-growth approaches that prioritize well-being and community resilience, contributing to SDG 3 and SDG 10.
• Enhance collaboration across cities and governance levels to leverage horizontal and vertical policy synergies, advancing SDG 16 and SDG 17.
• Support local experimentation and innovation as pathways to sustainable urban transformation, promoting SDG 7 and SDG 9.

Conclusion

Addressing the growth versus environment debate at the urban scale is critical for achieving the Sustainable Development Goals. By understanding and integrating the economic, demographic, spatial, and environmental dimensions of urban growth, policymakers can design effective strategies that balance development with ecological sustainability and social equity.

1. Sustainable Development Goals (SDGs) Addressed or Connected

1. SDG 11: Sustainable Cities and Communities
   • The article focuses on urban growth dimensions including economic, population, spatial, and environmental aspects, which are central to making cities inclusive, safe, resilient, and sustainable.
   • Discussion on urban environmental policy and local experiments aligns with SDG 11’s aim to enhance sustainable urbanization.
2. SDG 13: Climate Action
   • The article addresses the growth-versus-environment debate, specifically relating to emissions and environmental impacts in cities, which is directly relevant to combating climate change and its impacts.
   • References to emissions and environmental policy connect to climate mitigation efforts.
3. SDG 8: Decent Work and Economic Growth
   • The economic growth dimension and narratives of green growth, degrowth, and post-growth relate to promoting sustained, inclusive, and sustainable economic growth.
4. SDG 12: Responsible Consumption and Production
   • Environmental dimensions and discussions on degrowth imply sustainable consumption and production patterns.

2. Specific Targets Under Identified SDGs

1. SDG 11: Sustainable Cities and Communities
   • Target 11.3: By 2030, enhance inclusive and sustainable urbanization and capacity for participatory, integrated and sustainable human settlement planning and management.
   • Target 11.6: Reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.
2. SDG 13: Climate Action
   • Target 13.2: Integrate climate change measures into national policies, strategies and planning.
3. SDG 8: Decent Work and Economic Growth
   • Target 8.4: Improve progressively, through 2030, global resource efficiency in consumption and production and endeavor to decouple economic growth from environmental degradation.
4. SDG 12: Responsible Consumption and Production
   • Target 12.2: By 2030, achieve the sustainable management and efficient use of natural resources.

3. Indicators Mentioned or Implied to Measure Progress
