Enga Highway Impact Assessment: Measuring real-world impact using Earth Observation technology

This collaboration represents a pivotal step in measuring and enhancing the real-world impact of our projects in alignment with the United Nations Sustainable Development Goals (SDGs). By integrating Rural Senses’ participatory and data-driven methodologies, we are assessing the environmental, social, and economic benefits of our work more effectively.
We are using the Rural Senses technology to assess the impacts of our work on the communities surrounding the Enga Highway where AnyWay’s climate resilient design and engineering solutions have played a key role in the highway’s rehabilitation and upgrade.
Using Earth Observation to Measure Real-World Impact
In this phase of the study, the evaluation uses mixed methods, leveraging Earth Observation (EO) data to complement the traditional process of in-person surveys used to understand communities’ needs and perceptions. Through this process we can create a richer, more objective view of long-term development impact on the region, related to the work we have been involved in upgrading the highway. In doing so, we combine local insights from community engagement tools with our geospatial analytics and engineering expertise to track the actual impact on the surrounding areas.
EO as a Tool for Measuring Community / Economic Growth
Using earth observation , we analyzed changes along the corridor of the Enga Highway, a 67kom long road, through the years 2017 to 2024. This period was chosen to track the years following the completion of the rehabilitation of the Highway in 2017, enabling us to collect data points that could be compared to the prior period. This included quantifiable signals of urban growth, visualized through color-coded land cover maps (see image), revealing significant expansion of built-up areas and agriculture development around towns adjacent to the highway. Through combining the on-the-ground surveys with EO technologies we link quantitative data on geographic changes and expansion with qualitative social and economic data from surveys. This also enables us to identify high-impact zones for future infrastructure investments and interventions.

Above, is a clip of the Sentinel-2 10m Land Use-Land Cover Time Series data produced by Impact Observatory and Esri. When the slider bar is moved to the left, you can see the red areas indicating built-up areas of more densely populated areas in back in 2017. With the slider moved to the right, you can see there are areas with developed towns adjacent to the highway, signaling significant urban expansion within the area up to 2024.
Beyond A Map: A Multi-Dimensional View
In parallel with the earth observation technologies, AnyWay field staff have been conducting surveys throughout the community to gather qualitative data on the direct impacts to community-members. Using both anecdotal, in-person interviews and enhancing it with data collected through satellites allows us to achieve a multi-dimensional perspective that includes measurable geographic outcomes. When we overlay EO-derived land use changes with Rural Senses’ qualitative data—on employment, access to services, and community well-being—we start to build a multi-dimensional view of development. We will go more in depth
Forward Looking – The future is here
At AnyWay Solutions, our goal is not just to provide designs and solutions that are focused on climate resiliency for transport infrastructure but also to ensure it contributes to long lasting, inclusive development. With partners like Rural Senses and tools like Earth Observation, we’re changing how impact is measured and being evaluated in developing nations.
