Meeting the challenges posed by per diem in development projects in southern countries: a scoping review

This study presents the results of a review whose goal is to generate knowledge on the possible levers of action concerning per diem practices in southern countries in order to propose reforms to the existing schemes.

A synthesis of available knowledge was performed using scoping review methodology: a literature search was conducted using several databases (Medline, Cinahl, Embase, PubMed, Google Scholar, ProQuest) and grey literature. A total of 26 documents were included in the review. Furthermore, interviews were conducted with the authors of the selected articles to determine whether the proposed recommendations had been implemented and to identify any outcomes.

For the most part, the results of this review are recommendations supporting per diem reform. In terms of strategy, the recommendations call for a redefinition of per diems by limiting their appeal. Issued recommendations include reducing daily allowance rates, paying per diem only in exchange for actual work, increasing control mechanisms or harmonizing rates across organizations. In terms of operations, the recommendations call for the implementation of concrete actions to reduce instances of abuse, including not paying advances or introducing reasonable flat-rate per diem. That said, the authors contacted stated that few per diem reforms had been implemented as a result of the issued recommendations.

The results of the study clearly identify possible levers of action. Such levers could make up the groundwork for further reflection on context and country-specific reforms that are carried out using a dynamic, participatory and consensual approach.
