Method: Geospatial analysis using remote sensing and GIS.
Evidence: Strong effect

Accelerated development in river basins, characterized by increased built-up areas and shifts in land use, directly correlates with a rise in land surface temperature and a decrease in vegetation cover. This resource management research insight is drawn from a 2023 study published in Geomatics Natural Hazards and Risk. Using Geospatial analysis using remote sensing and gis., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate geospatial analysis of LULC, LST, and NDVI into the early stages of design and planning for development projects in river basins to proactively manage environmental impacts.

Application

Design takeaway

Integrate geospatial analysis of LULC, LST, and NDVI into the early stages of design and planning for development projects in river basins to proactively manage environmental impacts.

How to apply

Before commencing any large-scale development project in a river basin, conduct a geospatial analysis to map current LULC, LST, and NDVI. Use this data to predict potential environmental changes and design mitigation strategies.

Project actions

01When researching environmental impacts, consider using satellite imagery to track changes over time.
02Look for correlations between different environmental factors, like temperature and vegetation.

Method & Evidence

AimTo identify vulnerable areas within the Lower Manair River basin by analyzing land-use/land-cover changes, land surface temperature, and vegetation index over a six-year period.

MethodGeospatial analysis using remote sensing and GIS.

ProcedureSatellite imagery from Landsat 8 was analyzed for the years 2015 and 2021 to classify land-use/land-cover (LULC). Changes in LULC, land surface temperature (LST), and normalized difference vegetation index (NDVI) were detected and correlated.

ContextRiver basin environmental management and urban/rural development planning.

Variables

IVLand-use/Land-cover changes (e.g., increase in built-up area, agricultural expansion)

DVLand Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI)

CVGeographic location (Lower Manair River basin), Time period (2015-2021), Satellite data source (Landsat 8)

Strengths & Limitations

Strengths

+Utilizes robust geospatial technologies for objective environmental monitoring.
+Provides quantitative data on environmental changes over a defined period.

Limitations

Access to high-resolution satellite imagery and the expertise to analyze it can be a barrier. Local environmental conditions can significantly influence the results.

Reliability & validity

The use of standardized satellite data and established geospatial analysis techniques enhances reliability. Validity is supported by the observed correlations between LULC changes and environmental indicators.

Think critically

To what extent can geospatial technologies accurately predict the long-term environmental consequences of specific development proposals?

Design Principles

"Environmental impact is directly proportional to the rate and type of land-use change."

Understanding these environmental shifts is critical for sustainable resource management. Designers and planners can use this information to anticipate the ecological impacts of development projects and implement strategies that mitigate negative environmental consequences, ensuring long-term resource availability and ecosystem health.

What This Means for Your Design

When areas develop quickly, especially with more buildings and farms, they tend to get hotter and have less greenery.

How to use in your project

1.Use this study as a precedent for investigating the environmental impacts of land-use changes in your own design project's context.
