How Hengelo Used Data to Gain Better Insight into Urban Green
How can cities understand where urban green is improving and where attention is needed? Hengelo shows how spatial data can make green trends visible and support better-informed policy decisions.
Turning Urban Green Ambitions into Measurable Insight
Urban greening is becoming increasingly important for liveable and climate-resilient cities. Trees, parks and other green spaces can contribute to cooling, biodiversity, water retention and healthier neighbourhoods. However, setting green ambitions is only the beginning. Cities also need to understand where green is located, how it is distributed and how it changes over time.
The Dutch municipality of Hengelo provides a practical example of how spatial data can support that process. By analysing urban green geographically, developments become easier to identify and policymakers gain a clearer basis for decisions around liveability, climate adaptation and future investment. MapGear presents the Hengelo approach as a practical example of using data to make urban green trends visible.

Urban Green Is More Than a City-Wide Percentage
A single percentage for the entire municipality does not show how residents actually experience green space.
One neighbourhood may have substantial tree cover and easy access to parks, while another has much less shade and fewer green spaces nearby. Looking only at a municipal average can hide these differences.
Spatial analysis adds the missing context. By connecting green indicators to specific neighbourhoods, streets and buildings, municipalities can see where green is concentrated and where opportunities for improvement are located.
This changes the discussion from “How green is our municipality?” to more useful questions such as:
Which neighbourhoods have the least access to green?
Where is tree canopy cover relatively low?
Which areas may be more vulnerable to heat?
Where has green increased or disappeared over time?
Which locations could benefit most from additional greening?
Making Green Trends Visible
Green policy becomes more useful when municipalities can compare different moments in time.
Historical and current spatial data can reveal where tree canopy has increased, where vegetation has disappeared and which neighbourhoods are developing differently from the rest of the city. Instead of relying only on individual projects or tree-planting totals, policymakers can begin to see broader patterns.
That matters because planting trees does not automatically mean that total urban green is increasing. Trees may also be removed elsewhere, development can increase hard surfaces and young planting may take years to provide the same canopy as mature vegetation.
Monitoring change therefore creates a more complete picture of how the urban environment is evolving.
From Data to Better Priorities
The real value of green data appears when it helps determine where action is most useful.
By combining information about urban green with other spatial datasets, municipalities can identify areas where several challenges overlap. A neighbourhood with limited canopy cover may also experience higher heat stress, more hard surfaces or lower access to public green space.
This allows green policy to support several objectives at the same time. Investments in trees or green infrastructure can potentially contribute to:
climate adaptation
heat reduction
biodiversity
water retention
public-space quality
neighbourhood liveability
Instead of treating these themes separately, a spatial overview helps policymakers understand where interventions may create multiple benefits.
Hengelo as a Practical Example
The approach used in Hengelo demonstrates how data-driven green monitoring can move policy beyond general ambitions.
Spatial analysis makes it possible to compare areas within the municipality and identify where developments deserve closer attention. This gives policymakers a more concrete starting point for discussing priorities and evaluating how the urban environment changes.
The Hengelo example is particularly relevant because the same underlying challenge is becoming more important across Europe. Cities increasingly need reliable information about urban green, tree canopy and long-term change, both for their own climate and biodiversity policies and in response to broader developments such as the European Nature Restoration Regulation.
The value of the approach therefore extends beyond one municipality. Hengelo shows how local green data can become a practical management and policy tool rather than remaining a collection of disconnected datasets.
Monitoring Instead of One-Off Analysis
A one-time green analysis provides a useful snapshot, but structural monitoring creates much more value.
When the same indicators are measured consistently, municipalities can see whether interventions are delivering the intended results. They can also identify unexpected changes earlier and adjust priorities when necessary.
Over time, this creates a clearer evidence base for questions such as whether tree canopy is increasing, whether neighbourhood differences are narrowing and whether investments are improving access to green space.
Monitoring also makes communication easier. Instead of discussing green ambitions only in abstract terms, policymakers can show how specific areas are developing and explain why particular locations receive attention.
Connecting Green Data to Wider Urban Challenges
Urban green does not exist in isolation. The same locations are affected by housing development, mobility, heat, water management and other spatial priorities.
Bringing these datasets together helps municipalities understand where objectives support each other and where trade-offs may arise. For example, an area targeted for new housing may also have limited tree canopy and high heat exposure. Seeing those factors together makes it easier to include green infrastructure earlier in the planning process.
This is where platforms such as ESG Maps can add value. MapGear’s sustainability platform brings sustainability information together spatially and provides tools for analysis and monitoring across themes such as climate adaptation, heat and urban green.
From Green Data to Better Urban Decisions
The lesson from Hengelo is straightforward: urban green becomes easier to manage when it is measurable and spatially visible.
Data does not replace policy judgement, but it gives policymakers a stronger basis for deciding where attention is needed, comparing neighbourhoods and monitoring whether interventions are having an effect.
As cities face growing pressure around climate adaptation, biodiversity and liveability, this type of spatial insight becomes increasingly valuable. The question is no longer simply how much green exists, but where it is, who benefits from it and how it is changing over time.
