GAP FUND TECHNICAL NOTES – Low-Carbon Slum Upgrading
The document “Low-Carbon Slum Upgrading” presents a strategic framework for integrating low-carbon solutions into slum upgrading initiatives. It highlights the urgent need to adopt sustainable practices in urban development, particularly in slums, which are often characterized by inadequate infrastructure and high carbon emissions. The report emphasizes that implementing low-carbon strategies not only addresses climate change but also improves the quality of life for residents.

The GAP Fund Technical Notes on Low-Carbon Slum Upgrading provide essential insights into integrating low-carbon solutions within slum upgrading initiatives. These notes emphasize the importance of adopting low-carbon pathways to avoid carbon lock-in associated with traditional upgrading methods and to align with climate goals such as the Paris Agreement and Sustainable Development Goals (SDGs).
The technical notes outline several approaches to slum upgrading, each offering unique opportunities for climate mitigation:
In-situ Upgrading: Improving existing structures while retaining residents in their homes, which can include using low-emission building materials and energy-efficient technologies.
Land Readjustment: Reconfiguring land use to optimize space and resources while promoting sustainable practices.
High-Rise Redevelopment: Constructing vertical housing solutions to maximize land use in densely populated areas.
Relocation: As a last resort, moving residents to new sites when upgrading is not feasible.
Importance of Low-Carbon Slum Upgrading
As urban populations continue to grow, slums are emerging as critical areas where sustainable development must be prioritized. The document argues that conventional slum upgrading methods often lead to carbon lock-in, which can hinder future efforts towards achieving carbon neutrality. By adopting low-carbon pathways, cities can reduce their overall carbon footprint while enhancing resilience against climate-related challenges.
Objectives of the Document
The primary objectives of the report are twofold:
- Highlighting the Need for Low-Carbon Solutions: It underscores the importance of incorporating low-carbon strategies into city investments aimed at climate mitigation.
- Demonstrating Practical Solutions: The document showcases affordable and adaptable low-carbon solutions that have been successfully implemented in various slums worldwide.
Approaches to Low-Carbon Development
The report categorizes different approaches to slum upgrading, emphasizing that each method presents unique opportunities for integrating low-carbon solutions. Key approaches include:
- In-situ Upgrading: This involves improving existing slum infrastructure without displacing residents. It allows for the use of local materials and energy-efficient technologies, which can significantly reduce emissions.
- Land Readjustment: This strategy focuses on reorganizing land use within slums to improve access to services while minimizing environmental impact.
- High-Rise Redevelopment: In areas where space is limited, constructing vertical housing can optimize land use and reduce the carbon footprint associated with sprawling developments.
- Sites and Services: This approach provides basic services and infrastructure in new developments while ensuring that environmental considerations are prioritized.
Low-Carbon Solutions
The document outlines several low-carbon solutions applicable to various aspects of slum upgrading:
- Building Materials: Utilizing local and recycled materials can significantly lower emissions compared to conventional construction methods that rely on concrete and steel transported over long distances.
- Energy Efficiency: Implementing energy-efficient technologies, such as solar panels and improved insulation, reduces reliance on grid energy and lowers utility costs for residents.
- Water and Sanitation: Sustainable water management practices, including rainwater harvesting and eco-friendly sanitation systems, contribute to both environmental sustainability and public health.
- Waste Management: Introducing solid waste management systems that promote recycling and composting can minimize landfill use and reduce greenhouse gas emissions.
- Transportation Solutions: Enhancing public transportation options within slum areas can decrease reliance on personal vehicles, thereby reducing traffic congestion and emissions.
Co-Benefits of Low-Carbon Upgrading
Beyond reducing carbon emissions, low-carbon slum upgrading offers numerous co-benefits:
- Economic Opportunities: By creating jobs in green construction and maintenance, these initiatives can stimulate local economies.
- Health Improvements: Enhanced living conditions lead to better health outcomes for residents by reducing exposure to environmental hazards.
- Community Resilience: Strengthening Infrastructure against
