GIS: Myths, Reality, and the New Tools of Today

There are a lot of misconceptions about using geographical information systems (GIS) in development: that it’s a niche tool, or one that requires a large budget and major technical expertise. These are often paired with some of the even bigger myths in development, like the idea that more data is always better data.

Fact-check time: With the right tools in place, the data-to-geographic-visualization process is straightforward and pain-free for non-techies. It can also be really, really useful for telling a story, illustrating an impact or aiding decision making. And the right tools mean it’s not about getting more data, it’s about organizations being able to effectively analyze what they already have: quality over quantity.

So why is GIS such a good fit for the field of development? Several reasons, really: we talk a lot about the local context and the importance of tailoring interventions to on-the-ground realities. Bringing geographic tools into the project cycle lets that happen at every stage: from planning to implementation and monitoring. This can let an organization’s internal audiences visualize what works and what doesn’t. Geospatial tools are particularly helpful for identifying underserved areas and fragmentation of effort — which can ideally lead to improved coordination among development actors.

For example, take the geospatial analysis below conducted by the AidData Center for Development Policy. The initial goal of this evaluation was to identify whether education funding was actually going to areas in the country of Nepal with the highest demonstrated need. To conduct this analysis, AidData researchers first loaded data about illiteracy rates (see map on left), then combined this information with funding data. Places where illiteracy was high but funding low, or where illiteracy was low but funding high are identified in the map on the right, illustrating “aid mismatches”.

Analysis like this can allow government officials and development partners to adjust funding to meet demonstrated need and maximize aid effectiveness.

Where we often see the greatest knowledge gains is with GIS tools that tap into an organization’s existing information management systems. This means they build on data that has already been collected, significantly reducing costs and keeping organizations from having to overhaul existing reporting or M&E systems. It also means they don’t need a cabal of PhDs on staff to use GIS in decision-making processes. With the right systems in place, this data-to-visualization process can be straightforward and pain-free for techies and non-techies alike – making analytics more accessible, and data-driven decision making more realistic.

“Data…for What?!:” Expanding into Education, Media/Disinformation & Youth

In Episode 2 of "Data…for What?!," a podcast series from Development Gateway: an IREX Venture (DG) which explores our new strategic plan, Josh Powell met with experts from DG and IREX to discuss DG’s expansion into the education, media and disinformation, and youth sectors. The conversations explore the most pressing challenges and greatest opportunities for data and technology to positively impact these sectors and discuss how these trends are likely to play out in the years ahead. Based on these trends, the experts explain the unique fit for DG’s skills and specific opportunities for collaboration that align with the vision of DG’s partnership with IREX, which has a long and successful history working in each sector.

Introducing: Data… for What?!

To help contextualize the new Strategic Plan, we are launching a podcast series called Data… for What?! This series consists of 5 episodes in Josh Powell and Vanessa Goas talk to DGers throughout the organization – as well as collaborators within our strategic partner, IREX - about how and why we prioritized the various elements of the new strategy. In this first episode, we talk to Kristin Lord, President and CEO of IREX about how our partnership fits into the Strategic Plan; and to Aleks Dardelli, Executive Vice President of IREX and Chair of DG’s Board of Directors, about the process of putting the Plan together at this opportune, yet precarious, global moment.
