Summary of Urban Environment and Infrastructure: Toward Livable Cities

Core Content

This document, Urban Environment and Infrastructure: Toward Livable Cities, is a comprehensive review of the World Bank's urban environment portfolio, conducted between 2002 and 2003. It aims to assess the Bank's commitment to urban sustainability, analyze the role of different sectors in improving urban environmental quality, and highlight the gaps and opportunities in current investments. The report also includes case studies from various countries, illustrating the diverse approaches and outcomes of urban environmental projects.

Main Findings

1. Urban Environment Portfolio Overview

• As of March 31, 2003, the World Bank had 264 ongoing operations aimed at improving urban environmental quality.
• 48% of these projects had improving urban environmental quality as the primary development objective.
• 43% had an urban environmental component as part of their broader goals.
• 9% included activities directly targeting urban environmental goals.
• The portfolio accounts for 20% of the Bank's total active operations, with a $12.02 billion investment, representing 12.6% of total lending commitments.

2. Sector Contributions

• Water and Sanitation projects accounted for 48% of the portfolio, focusing on water supply, sanitation, and wastewater management.
• Urban Development projects made up 22%, contributing to urban services, including solid waste management and slum upgrading.
• Environment projects represented 17%, addressing waste management, pollution control, and greenhouse gas reduction.
• Energy projects accounted for 5%, emphasizing energy efficiency and renewable energy sources.
• Other sectors, such as Transport, Social Protection, and Health, also contributed to the portfolio.

3. City Size and Regional Distribution

• Small cities received the majority of projects, with 70% of the Bank's urban environmental projects concentrated in cities with populations under 1 million.
• Megacities in East Asia received significant investment, highlighting the region's focus on urban environmental issues.
• The South Asia Region had the lowest investment per urban resident, while the Europe and Central Asia Region had the highest.

4. Role of Local Stakeholders

• Local governments were involved in 34% of projects, often playing a central role in implementation.
• Civil society organizations participated in 20% of projects, contributing to project design and implementation.
• The private sector was involved in 17% of projects, helping to improve service delivery efficiency.

5. Institutional and Technical Support

• Technical assistance focused on:
  • Strengthening sector agencies (45%),
  • Capacity building (65%),
  • Technical and sector studies (34%).
• Environmental management was supported in 22% of projects, including action plans, monitoring systems, and public education.
• Local urban strategies were rarely included in technical assistance components.

6. Contribution to Millennium Development Goals (MDGs)

• Urban environmental projects contribute to:
  • MDG 5 and 6: Reducing maternal and child mortality.
  • MDG 8: Preventing the spread of malaria and other diseases.
  • MDG 9: Integrating sustainable development principles into national policies.
  • MDG 10: Improving access to safe drinking water.
  • MDG 11: Enhancing sanitation and security of tenure for slum dwellers.

7. Monitoring and Evaluation

• Only two-thirds of projects included environmental indicators.
• One-quarter had explicit environmental indicators, such as pollution reduction.
• Only 5% used quality of life indicators to measure outcomes.

8. Case Studies

• Twelve case studies were included, representing projects from:
  • China: Liaoning Environment Project (focus on wastewater management and clean technology).
  • India: Bombay Sewage Disposal Project (sanitation and sewage management).
  • Colombia: Cartagena Water Supply, Sewerage and Environmental Management Project (water supply and sewerage).
  • Guinea: Third Urban Development Project (urban services, including solid waste management).
  • Venezuela: Caracas Slum-Upgrading Project (urban upgrading).
  • Nicaragua: Natural Disaster Vulnerability Reduction Project (disaster management).
  • Latvia: Municipal Solid Waste Management Project (solid waste, groundwater pollution, and greenhouse gas reduction).
  • Algeria: Industrial Pollution Control Project (industrial pollution).
  • Kenya, Tanzania, and Uganda: Lake Victoria Environmental Management Project (water resources and coastal zone management).
  • Poland: Krakow Energy Efficiency Project (energy efficiency).
  • Mongolia: Improved Household Stoves in Urban Centers Project (reducing indoor air pollution).
  • China: Guangzhou City Center Transport Project (urban mobility and emissions control).

Key Recommendations

• The World Bank should adopt a more comprehensive and integrated approach to urban environmental investments.
• There is a need to address regional and thematic gaps, particularly in smaller cities and megacities.
• Strengthening local institutions and engaging civil society and the private sector should be a priority.
• Monitoring and evaluation indicators should be expanded to include more quality of life and environmental impact measures.

Conclusion

The report emphasizes the importance of the urban environment as a public good and highlights the need for cross-sector collaboration, policy integration, and sustainable investment. It underscores the World Bank's role in supporting livable cities and the broader goals of urban sustainability, while also identifying areas for improvement in the Bank's current approach.
