Rapid urbanization in Lagos between 2000 and 2020 led to a significant increase in artificial terrain and a corresponding substantial conversion of agricultural land to urban use. This resource management research insight is drawn from a 2023 study published in Sustainability. Using Remote sensing, cellular automata (ca) markov model, markov chain transition matrix, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for urban environments or products that support urban living, consider the impact on surrounding agricultural and natural resources, and explore solutions that minimize land conversion.

Application

Design takeaway

When designing for urban environments or products that support urban living, consider the impact on surrounding agricultural and natural resources, and explore solutions that minimize land conversion.

How to apply

When designing a new housing development or a product that encourages urban expansion, consider the potential impact on local food production and natural habitats.

Project actions

  • 01When analyzing a product's life cycle, consider its impact on land use and resource conversion in its production and disposal phases.
  • 02Investigate how the materials used in your product might be sourced from or impact agricultural or natural land.

Method & Evidence

AimTo monitor and predict urban growth patterns in Lagos City using remote sensing and integrated models, and to analyze the resulting land-use and land-cover changes.
MethodRemote Sensing, Cellular Automata (CA) Markov Model, Markov Chain Transition Matrix
ProcedureUtilized Global Land 30 (GL30) data, nighttime light observations, and built-up/population density data to monitor urban growth from 2000-2020. Applied CA-Markov model for land-use/land-cover (LULC) change prediction and a Markov Chain Transition Matrix to forecast future LULC changes.
ContextUrban planning and environmental monitoring of megacities, specifically Lagos, Nigeria.

Variables

IVTime period (2000-2020), Urbanization policies/drivers.
DVPercentage of artificial terrain, Percentage of cultivated land, Percentage of other land cover types.
CVGeographical area (Lagos City), Remote sensing data resolution, CA-Markov model parameters.
04

Strengths & Limitations

Strengths

  • +Integration of multiple data sources (GL30, nighttime lights, density data).
  • +Application of established predictive modeling techniques (CA-Markov).

Limitations

The models used are simplifications of complex real-world processes. The accuracy of the predictions depends heavily on the quality and completeness of the input data.

Reliability & validity

Reliability is supported by the use of established remote sensing and modeling techniques. Validity is enhanced by the integration of multiple data types, but the predictive nature of the models introduces potential for future invalidity if underlying assumptions change.

Think critically

To what extent can design innovation in urban planning and housing mitigate the conversion of agricultural land, and what are the trade-offs involved?

05

Design Principles

"Prioritize resource efficiency and minimize negative environmental externalities in design solutions for growing urban populations."

This highlights the critical tension between development needs and resource preservation. Designers must consider the environmental impact of urban expansion, including the loss of productive agricultural land and the strain on natural resources.

06

What This Means for Your Design

As cities grow, they often use up farmland. In Lagos, this growth meant more buildings and roads, and a lot more farmland was turned into urban areas by 2020.

How to use in your project

  • 1.Use this insight to justify the selection of sustainable materials that minimize land conversion or to design products that reduce the need for urban sprawl.
  • 2.In your analysis of existing products, consider their contribution to or mitigation of land-use changes.

Paragraph starter

The rapid urbanization observed in megacities like Lagos, as evidenced by the significant increase in artificial terrain and conversion of agricultural land, presents a critical challenge for resource management. Designers must consider the environmental footprint of their creations, particularly concerning land use, to promote sustainable development and mitigate the loss of vital agricultural resources.
