A Credible Tool

In 2005 when the PPI was launched, Grameen Foundation set out to prove the concept. They closely observed the first organizations to adopt the tool so that they could understand its accuracy and feasibility. Today, demand and acclaim for the PPI validates our belief that the concept is proven.

But don’t take our word for it. The following publications, written by third parties without Grameen Foundation or IPA’s influence, detail the ways in which the PPI can benefit development practitioners.

  • Testing the PPI in the COSA Platform
    The Committee on Sustainability Assessment (COSA), a global consortium that researches and promotes science-based impact assessment tools for agricultural producers, tested the PPI and found that it was highly correlated with net income from crops and food security. The results provided COSA with confidence to incorporate the PPI into its impact assessment framework.
