Conceptual Foundation

2. Understanding Climate Risk

ClimateReady's approach draws on the conceptual framework used by the Intergovernmental Panel on Climate Change (IPCC) to understand climate-related risk.

Hazard × Exposure × Vulnerability = Climate Risk

In the IPCC's Sixth Assessment Report framework, climate risk arises from the interaction of hazard, exposure and vulnerability. These concepts help explain why the same environmental event can have different consequences in different places.

Hazard

What could cause harm?
A hazard is a potentially damaging event or trend, or a physical impact associated with climate change.
Examples: Extreme heat waves and intense rainfall. In air pollution, harmful pollutant concentrations act as an environmental hazard.

Exposure

Who or what is in harm's way?
Exposure refers to the presence of people, livelihoods, species, ecosystems, infrastructure or other assets in places that could be adversely affected.
Examples: A densely populated neighbourhood exposed to extreme heat, or a major transport corridor exposed to water accumulation.

Vulnerability

How susceptible are they to harm?
Vulnerability is the propensity or predisposition to be adversely affected, including susceptibility to harm and capacity to cope or adapt.
Examples: Low vegetation, extensive paved surfaces, low-lying terrain, or limited drainage capacity.

Risk

What is the potential for harm?
Risk results from the interaction of hazard, exposure and vulnerability. The likelihood and severity of harm depend on how these interact.
Context: Two neighbourhoods with the same hot day experience different consequences if one has trees and shade while the other is paved.

How does ClimateReady apply these concepts?

ClimateReady uses spatial environmental indicators to assess and map relative risk patterns across a selected region for urban heat, waterlogging and air-pollution exposure. The indicators help characterise the environmental conditions associated with risk. The resulting maps allow users to compare locations, investigate the factors behind their scores and explore possible actions.

An Important Distinction

The IPCC framework provides the conceptual foundation for understanding risk. A map generated from a selected set of indicators is an operational assessment of risk under ClimateReady's methodology; it is not automatically a complete quantification of all hazard, exposure and vulnerability components described by the IPCC. The scope of each map depends on the data and calculations actually used in that module.

Click any of the three assessment modules below to expand its full assessment scope, complete indicator breakdowns, vulnerability score explanations, and actionable interventions. (All closed by default).

What are we assessing?

Urban Heat Island (UHI) describes the tendency for urban areas to be warmer than surrounding less-developed areas, often because of built surfaces, reduced vegetation and changes in how heat is absorbed, stored and released.

ClimateReady examines environmental characteristics associated with urban surface heating to identify areas that may be more susceptible to heat-related conditions.

Indicators Used

Land Surface Temperature

LST

LST estimates the temperature of the land surface as observed by a satellite. It helps identify areas where the ground, roofs and other visible surfaces are relatively hot.

LST is not the same as the air temperature reported in a weather forecast, nor does it directly measure a person's heat exposure.

Vegetation Index

NDVI

NDVI is a satellite-derived index used to estimate the presence and relative greenness of vegetation. Areas with healthy vegetation benefit from shade and evaporative cooling.

Lower vegetation levels can indicate reduced natural cooling, although NDVI alone does not describe every aspect of vegetation quality or accessibility.

Built-up Index

NDBI

NDBI is a satellite-derived index used to help distinguish built-up surfaces from other land-cover types. Higher built-up signals indicate extensive construction and impervious surfaces influencing heat storage.

NDBI is an indicator, not a direct measurement of building density or heat.

Land Use & Land Cover

LULC

LULC describes the types of surfaces present in an area, such as built-up land, vegetation, water and bare ground. Different surface types absorb, reflect and store heat differently.

Helps characterise the spatial composition of the urban landscape.

Albedo

Reflectivity

Albedo describes the proportion of incoming solar radiation reflected by a surface. A surface with higher albedo reflects more incoming sunlight, while lower-albedo surfaces absorb more.

Influence on surface heating also depends on thermal storage, shading and moisture.

What might a higher vulnerability score indicate?

Depending on the implemented indicators and their weights, a higher score may be associated with relatively high surface temperatures, extensive built-up surfaces or limited vegetation.

What actions might help?

Potential measures include increasing tree cover where suitable, improving shade along walking routes, protecting existing green spaces, introducing appropriate cool-surface treatments and incorporating heat-sensitive design into urban planning. Note: A vulnerability score alone does not establish which intervention delivers the greatest cooling benefit.

What are we assessing?

Waterlogging occurs when water accumulates on land or streets because water cannot drain away or infiltrate quickly enough.

Its occurrence depends on several interacting conditions, including rainfall, terrain, surface permeability, drainage capacity and the surrounding landscape. ClimateReady examines selected environmental and geographic characteristics that may influence susceptibility to water accumulation.

Indicators Used

Digital Elevation Model

DEM

A DEM represents the elevation of the land surface. Elevation helps identify relatively low-lying areas where water may collect.

Elevation alone cannot determine whether a location will flood or become waterlogged.

Slope

Terrain

Slope measures how steeply the land rises or falls. Gentle slopes and depressions favour water accumulation, while steeper terrain encourages runoff to move more quickly.

The actual effect depends on local drainage and surface conditions.

Rainfall

Precipitation

Rainfall describes the amount of precipitation received. Heavy or prolonged rainfall increases the volume of water that must be absorbed, stored or drained.

Dataset time period and spatial resolution affect how well it represents local cloudbursts.

Impervious Surface

Runoff

Impervious surfaces (concrete, asphalt, paved roads) limit the infiltration of rainwater into the ground, drastically increasing surface runoff volume.

Places significant additional pressure on local stormwater drainage systems.

Distance to Water Bodies

Hydrology

Measures how far a location is from mapped rivers, lakes, wetlands or coastline to provide geographic hydrological context.

Proximity does not independently establish waterlogging; relevance depends on water body type.

Distance to Drainage

Infrastructure

Describes the spatial relationship between an area and mapped stormwater drainage infrastructure.

Being close to a drain does not guarantee drainage: capacity, blockage, and maintenance matter.

Soil Type

Infiltration

Soil characteristics influence how quickly water can infiltrate and percolate through the ground into the aquifer.

Infiltration rate also depends on compaction, saturation, and land cover.

Vegetation Index

NDVI

Vegetation can intercept rainfall, support soil infiltration and slow surface runoff velocities under suitable conditions.

Does not directly measure infiltration or total absorption capacity of root systems.

Land Use & Land Cover

LULC

Characterises built-up areas, tree cover, water, and open ground to evaluate land conversion impacts on runoff.

Helps distinguish natural sponges from dense sealed construction zones.

What might a higher vulnerability score indicate?

A higher score may reflect a combination of conditions associated with water accumulation, such as low-lying terrain, limited infiltration, extensive impervious surfaces or particular drainage relationships.

What actions might help?

Potential measures include maintaining drains, clearing blocked inlets, improving local stormwater infrastructure, preserving permeable surfaces, restoring suitable green spaces and using rain gardens or nature-based drainage measures where feasible. Note: Some locations require structural drainage engineering rather than surface interventions alone.

What are we assessing?

Air pollution is the presence of harmful substances in the air. People's exposure depends on pollutant concentrations, how long they spend in affected places, their activities and other factors.

ClimateReady's air-pollution module examines selected environmental and built-up characteristics associated with susceptibility to pollution exposure or pollutant accumulation. Important: This module does not necessarily measure actual pollutant concentrations. Its vulnerability score should not be interpreted as an Air Quality Index (AQI), a PM2.5 concentration reading or a direct estimate of an individual's health risk.

Indicators Used

Road Density

Traffic

Road density describes the concentration of roads within an area, highlighting zones with greater potential exposure to vehicular tailpipe emissions.

Road density alone cannot determine actual traffic volume, vehicle fleet mix or real-time emissions.

Land Surface Temperature

LST

Measures surface heat to characterise the local microclimate and boundary layer conditions.

Not a direct measurement of airborne pollution or proof that a hotter area has higher pollutant concentrations.

Built-up Intensity

NDBI

Built form can influence urban ventilation, airflow friction and pollutant trapping in street canyons.

NDBI alone cannot determine street-canyon geometry, building height or aerodynamic dispersion.

Wind Speed

Ventilation

Wind influences the transport, dilution and dispersion of air pollutants across an urban basin.

Stronger winds can disperse emissions, but direction, terrain and sources produce varied local outcomes.

Vegetation Index

NDVI

Vegetation may influence local environments through particulate deposition, shading and changes in airflow patterns.

Effects vary by tree species and canopy structure; vegetation should not be assumed to eliminate pollution in every setting.

What might a higher vulnerability score indicate?

A higher score may indicate a combination of environmental characteristics associated with potential susceptibility to pollution exposure or accumulation, according to the scoring framework. It does not confirm that pollutant concentrations are higher at that exact location.

What actions might help?

Potential measures include reducing unnecessary vehicle idling, supporting cleaner transport, improving traffic management, protecting suitable green buffers and conducting air-quality monitoring near potentially exposed communities. Note: Transport planning and emission standards require action by public authorities.

Interpretation Guide

5. Understanding Your Vulnerability Map

ClimateReady groups the resulting assessment scores into five classes to make spatial patterns easier to interpret.

Very Low

The area falls within the lowest assessment class. Its score reflects relatively lower contributions from the indicators in the implemented framework.

Low

The area falls within a relatively low assessment class. It may still contain local issues that are not captured by the available data.

Moderate

The area falls within the middle assessment class and may warrant closer examination of its environmental characteristics.

High

The area falls within a higher assessment class and may deserve priority for further investigation or suitable interventions.

Very High

The area falls within the highest assessment class and may warrant particular attention when setting priorities for follow-up assessment and action.

What do the classes actually mean?

These categories describe the assessment score—not a universal probability of an event, a measured amount of harm or an official warning level.

A Very High score does not necessarily mean that an event will occur, and a Very Low score does not mean that an area is completely safe. The classification method and score thresholds determine how the classes should be interpreted. When classes are generated using relative thresholds, a location's class may also depend on the other locations included in the assessment.

Why explore the individual indicator maps?

The composite map summarises multiple indicators into one view. Individual indicator maps help you understand the environmental patterns contributing to that summary.

For example, a location with a high heat-vulnerability score may also have high surface temperatures and limited vegetation. Examining these layers separately helps users interpret the score rather than treating it as an unexplained number. However, the composite score and its indicators should be interpreted within the assumptions of the assessment framework.

Action Framework

6. From Vulnerability to Recommendations

Identifying vulnerable areas is only the first step. The next is to explore what could be done. ClimateReady connects the assessment to recommendations intended to help users consider appropriate responses to the environmental conditions identified in the selected region.

Individual Level

Actions that people can take in their daily routines or immediate surroundings, where appropriate — such as maintaining domestic cool roofs, installing rainwater barrels, or timing outdoor travel during low-pollution windows.

Community Level

Measures that residents, housing societies, community groups or local organisations may be able to coordinate — such as neighborhood tree planting, permeable courtyard paving, community shade networks, and drain-cleaning drives.

Municipal & Planning Level

Actions that may require public authorities, infrastructure investment, technical assessment or changes in planning and maintenance — including arterial drain expansion, urban zoning, green corridors, and public transit decarbonisation.

Why level of action matters: Not every environmental problem can be solved by individuals. A drainage bottleneck may require engineering and maintenance, while a neighbourhood with inadequate shade may benefit from community planting as well as public-space planning. Recommendations are intended to guide further consideration. Their feasibility, costs and expected benefits depend on local circumstances and should be assessed before implementation.

Methodological Rigour

7. Data, Reliability and Validation

ClimateReady depends on the quality, spatial resolution, time period and coverage of the underlying datasets.

Satellite observations, terrain data, rainfall records, road networks and other geographic datasets provide different types of information. They do not all measure the same phenomenon or represent conditions at the same spatial and temporal resolution.

To make the assessment more consistent, the framework prepares and standardises indicators before combining them. Where applicable, methodological checks can examine the consistency of weighting decisions, the sensitivity of results to changes in assumptions and the agreement between mapped patterns and independent observations.

Consistency Checks

Are the weighting decisions internally consistent? Verifies multi-criteria weight distributions and normalisation bounds across environmental layers.

Sensitivity Assessment

Do the results change substantially when indicator weights or assumptions change? Ensures composite risk scores are robust and not overly fragile to minor weight alterations.

Independent Cross-Checking

Are the mapped patterns broadly consistent with reliable local observations or external datasets? Ground-truth comparison where local records exist.

Validation Caveat: A mathematically consistent weighting scheme does not automatically prove that a vulnerability map is accurate. Independent validation requires suitable reference data, and its strength depends on the quality and coverage of that data. Details of validation should be reported only where the relevant checks have actually been performed.

Platform Boundaries

8. Limitations of ClimateReady

ClimateReady is designed as a screening and decision-support platform. It is not intended to replace detailed scientific studies, official warnings, field surveys or professional engineering assessments.

1. Indicator-based assessment

The maps are derived from selected indicators and the assumptions used to combine them. They represent the conditions captured by the framework, not every factor that can influence environmental risk.

2. Data availability & quality

Some datasets may contain missing values, incomplete geographic coverage or differences in resolution and observation period. These limitations can affect the resulting spatial patterns.

3. Spatial resolution

The apparent detail of a map does not guarantee that every street, building or individual property has been assessed accurately. A map cell or mapped area may not capture small-scale conditions on the ground.

4. Temporal variability

Environmental conditions change over time. Satellite observations, rainfall records, wind data and land-cover datasets may represent different periods. The maps should not be assumed to describe current conditions unless the underlying data and update schedule support that interpretation.

5. Relative scores, not universal thresholds

The five classes are categories within the implemented assessment framework. They are not necessarily official risk thresholds and should not be interpreted as precise probabilities of harm.

6. Vulnerability ≠ measured hazard

A vulnerability assessment does not necessarily measure actual event frequency, pollutant concentrations, flood depth, human exposure or health outcomes. These require suitable additional data and methods.

7. Recommendations require local judgement

A recommendation that is appropriate for one neighbourhood may not be suitable for another. Feasibility, cost, local infrastructure, community needs and environmental impacts should be considered before implementing an intervention.

8. No guarantee of safety or prediction

ClimateReady cannot guarantee that a location is safe, predict exactly when an event will occur or establish the sole cause of a particular environmental problem.

Use ClimateReady as a starting point

ClimateReady helps users identify patterns, understand environmental indicators and explore possible actions. Its results are most useful when combined with local knowledge, field observations, reliable monitoring data and expert assessment where needed.

The goal is not to replace local expertise, but to make environmental information easier to understand and use in decisions.

Make Informed Local Climate Decisions

Explore your selected region, understand the environmental conditions associated with vulnerability, and use the results as a starting point for informed local action.
