In community-driven development (CDD) projects, communities that have been given control over planning decisions and investment resources for development often decide to undertake small-scale infrastructure projects, such as rural roads, small bridges or schools. A project in Benin has demonstrated that schools built by communities can be built faster at lower cost than those built by outside contractors.
An assumption behind CDD is that communities with local knowledge of resources and environment are better positioned to figure out the best way to build their own public infrastructure in their interest. Indeed, there is some evidence that community-built infrastructure can be cheaper when compared to infrastructure built by government or outside contractors (for example, Wong (2012) introduces several cases of “CDD’s cost effectiveness as compared to equivalent works built through other government service delivery mechanisms”).
However, much of the available evidence comes from a comparison between “community-built infrastructure” and “other-entity built similar infrastructure” constructed at a different time. It is difficult to find, or to set up, an experiment where a set of identical infrastructure projects are built by both communities and others at the same time under similar conditions, and in numbers large enough to allow for comparison between outcomes.
In this regard, the recently completed National Community Driven Development Project (“PNDCC” in French) and the Fast Track Initiative (FTI) Education project in Benin present just this type of “natural experiment.”
