Short answer

Designers should recognize that informal settlements are not static but evolve through predictable stages. This understanding should inform the design of interventions that are adaptive and responsive to these ongoing developmental processes.

The study demonstrates that informal settlements, often perceived as chaotic, follow a discernible developmental trajectory akin to established design principles, allowing for anticipatory urban design. This classic design research insight is drawn from a 2023 study published in Urban Science. Using Qualitative analysis of earth observation data with 50 informal settlements, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should recognize that informal settlements are not static but evolve through predictable stages. This understanding should inform the design of interventions that are adaptive and responsive to these ongoing developmental processes.

Key Findings

  • 01The IDS framework shows applicability across different global regions for understanding informal settlement development.
  • 02Informal settlements can progress through all IDS phases more rapidly than previously assumed.
  • 03Morphological differences exist between settlements in different regions, despite fitting the IDS framework.

Application

Design takeaway

Designers should recognize that informal settlements are not static but evolve through predictable stages. This understanding should inform the design of interventions that are adaptive and responsive to these ongoing developmental processes.

How to apply

When designing for areas undergoing rapid informal development, use the IDS framework to anticipate future growth patterns and plan for infrastructure and services accordingly.

Project actions

  • 01When studying an existing design, consider its historical development and how it has evolved over time.
  • 02Look for patterns of change and growth in user-generated designs or environments.

Method & Evidence

AimCan the Informal Development Stages (IDS) framework be applied globally to map densification and growth in informal settlements, and what are the implications for urban design?
MethodQualitative analysis of Earth Observation data
ProcedureResearchers analyzed Earth observation data from fifty informal settlements across five world regions, focusing on changes in densification and growth, and mapped these changes against the Informal Development Stages (IDS) framework.
Sample50 informal settlements
ContextUrban planning and design of informal settlements

Variables

IVInformal Development Stages (IDS) framework
DVDensification and growth patterns in informal settlements
CVEarth observation data, geographical region, change coefficient of settlements

Strengths & Limitations

Strengths

  • +Global applicability of the IDS framework was tested.
  • +Utilized Earth observation data for large-scale analysis.

Limitations

The visual interpretation of satellite imagery can be subjective. The speed of development can vary greatly, making precise timing difficult.

Reliability & validity

Reliability could be enhanced by having multiple researchers independently interpret the EO data. Validity is supported by the framework's fitment across diverse regions, but further validation with ground-truth data would strengthen it.

Think critically

To what extent can a universal framework like IDS account for the vast cultural, economic, and political differences that influence informal settlement development globally?

05

Design Principles

"Design interventions should acknowledge and integrate with the inherent evolutionary patterns of user-driven development."

Understanding these evolutionary stages provides designers and urban planners with a framework to anticipate development patterns in informal areas. This allows for more proactive and integrated design interventions that can better address the current and future needs of these communities.

06

What This Means for Your Design

Informal housing areas grow and get more crowded over time in predictable ways, like a plant growing through different stages. This helps designers plan better for these areas.

How to use in your project

  • 1.Reference this study when discussing the evolution of a design or the development of a user-generated environment.
  • 2.Use the IDS framework as a theoretical basis for analyzing the growth and densification of a chosen area for your design project.

Paragraph starter

This research highlights that informal settlements exhibit predictable stages of densification and growth, analogous to classic design principles of evolution and form following function. The study's findings suggest that an 'Informal Development Stages' (IDS) framework can be applied globally to anticipate urban development patterns in these areas, offering valuable insights for adaptive urban design and policy-making.
