Population Explorer™ for Determining Beneficiaries (Part 2)

Posted by India Young on September 4, 2018

Engineers, designers, and infrastructure planners make up a large Population Explorer user group. Last week, we introduced using Population Explorer for identifying well infrastructure beneficiaries. This week, we continue our discussion with a focus on bridge building.

Calculating Rural Beneficiaries of Bridge Infrastructure 

Bridges are a necessary infrastructure connecting communities in developing countries to services like education, healthcare, and jobs. For primary students trying to make it to class in the rainy season, bridges are essential to provide safe passage over rivers that they would otherwise have to wade through. For adults seeking job opportunities, bridges are key avenues to access employment opportunities outside their immediate communities. 

Engineers deciding where to place new bridges along waterways need to know how many people would benefit from the project at various locations. Beneficiaries of bridge projects in places like Guatemala are calculated by gathering any available population data from statistical offices as well as sending out field-survey teams. The data available are often outdated and in formats that are difficult to access and analyze. Sending personnel into the field is risky, expensive, and time consuming. 

With Population Explorer, the number of project beneficiaries can be determined in minutes. By placing buffers or customized boundaries around possible bridge locations, planners and engineers can quickly view population and demographic data for their catchment area. They can then quickly compare beneficiary data from multiple locations to find the site that best fits their project goals. For rural and remote locations, this advantage is especially beneficial. Below, we review a use case from Guatemala where two populations would potentially benefit from a new bridge over a river dividing their communities. Project leaders and engineers can further use Population Explorer to layer population and demographic information with environmental data to better inform their decision making.
