Understanding Regenerative Capacity
The idea of regenerative capacity draws inspiration from Pamela Mang and Bill Reed's concept of "operational capacity" for regenerative development—referring to systems' ability to self-organise, adapt, and evolve. It is also informed by the concept of “adaptive capacity”, popularised by the Intergovernmental Panel on Climate Change (IPCC) in their Third Assessment Report, referring to the capability of the ecosystem or community to adjust to potential damage or impact caused by climate change. While adaptive capacity measures a city's latent capability to respond to climate change, regenerative capacity extends this idea by distilling co-benefits.
Regenerative capacity aims to encourage synergies between the city's urban built and natural environments, advancing a balanced assessment of the urban ecosystem's ability to bring holistic benefits.
It comprises three fundamental tenets: density, diversity and connectivity. They each represent a systems-based approach to holistic planning. Collectively, they measure how well the urban built and natural environments can facilitate future regenerative urban development. While regenerative capacity does not guarantee regeneration, it indicates a potential development trajectory. Complementing this with a regenerative outcomes assessment will provide a measure of actual progress.
❶ Density Indicators
Density measures the concentration of human and ecological activity at a given site or district. It promotes the co-location of land uses in ways that generate shared benefits across liveability, ecosystem health and urban resource efficiency. It also embodies the principles of multi-functionality and integration that underpin low-carbon developments.

(2023) |
Tree Coverage | Proportion of district area covered by tree canopy From “Denser and greener cities: Green interventions to achieve both urban density and nature” by McDonald, R.I. et al. (2023) |
Cross-system Integration
Indicators for cross-system integration show how the city operates as an integrated urban environment. These include measuring shared green spaces, and greenery on horizontal and vertical surfaces.
Indicator | Metric |
|---|---|
Shared Green Space Ratio | Proportion of site area for shared use (parks, gardens, green roofs etc.) From Dense + Green Cities by Schröpfer, T. (2019), and Designing for Biodiversity: The Value of Nature Centric Design by WOHA & bioSEA (2024) |

Case Study: SkyVille @ Dawson in Singapore
SkyVille @ Dawson, a 47-storey public housing complex in Singapore, showcases how density can enhance liveability through the thoughtful integration of nature. Adopting the use of skyrise greenery, the complex incorporates 3 community terraces, each placed at 11-storey intervals, and a sky garden. In a dense environment, these areas are designed to provide community spaces for residents and neighbouring communities while accommodating skyrise greenery.
❷ Diversity Indicators
Diversity captures human and ecological activities across a site or district. These range from human vitality and economic competitiveness, to biodiversity in nature which reflect ecosystem health and capacity to support interspecies interactions.
Its indicators measure the variety and distribution of activities and species found in the district. They offer a cross-sectional view of social, economic and ecological conditions supporting a city's resilience by reducing reliance on a single system.

Case Study: Kampung Admiralty in Singapore
Kampung Admiralty is a mixed-use development that brings together multiple users and supports rich biodiversity. It co-locates public amenities and services for the old and young—such as senior living apartments and active ageing hubs, a childcare centre, and dining and retail outlets—enabling intergenerational engagements and cross-programming. Its terraced building form incorporates over 100 different plant species, with the intention to replicate a small, dense tropical rainforest. 218 unique species of fauna were recorded at the site in 2024.
❸ Connectivity Indicators
Connectivity measures accessibility of amenities and resources in a site or district, for people and natural ecosystems. Productive proximity of urban functions and landscapes facilitates movement and exchange. While roads, cycling paths, walkways and a public transport network enable the movement of people, ecological corridors and contiguous green infrastructure support natural environments.
Its indicators measure accessibility through the prevalence of mobility networks that enable the urban economy to function and people to move seamlessly within the city, as well as ecological corridors that provide vital links for biodiversity and connect people to nature.

The One Bangkok Urban Park in central Bangkok connects the One Bangkok mixed-used district to the nearby Lumphini and Benjakitti parks. It is a 80,000-m2 urban park that functions as an ecological bridge for the urban built and natural environments. This allows the One Bangkok district to leverage local ecosystem services that the neighbouring parks afford, such as alleviating urban heat, filtering polluted water and managing stormwater.
From Garden City to City in Nature: How Singapore's Green-Blue Networks Embody Regenerative Urban Living
Singapore's City in Nature vision proves that urban development can be optimised for co-benefits to create more good for both people and the environment. Through the lens of regenerative capacity, learn more about how NParks' approach to green-blue networks have created a living infrastructure for regenerative urban development.

Density, Diversity, Connectivity: Planning Singapore as a Regenerative City
Read more about how the Urban Redevelopment Authority has consciously applied the concepts of density, diversity and connectivity to plan and shape how Singapore functions socially, economically and ecologically. [By: Lim Eng Hwee, Chief Executive Officer, Urban Redevelopment Authority, Singapore]
Measuring capacity provides a point-in-time read into how well-configured a city is to support regenerative processes. It informs where deliberate action is needed to increase the city's regenerative capacity—whether by refining proposed regenerative policies to ensure alignment with existing capabilities or by adjusting planning parameters—actively shaping what the city chooses to do next.
