UNICEF/WFP Return on Investment for Emergency Preparedness (UNICEF/WFP, 2015). This study evaluated
the ROI to emergency preparedness, and found that prepositioning of emergency supplies can yield ROIs of
1.6–2.0, and generate significant time savings in response of between 14 and 21 days on average.
Evaluation of WFP Import Parity Approach (WFP, 2011). WFP’s import parity approach compares local and
international sourcing costs and delivery times for food. An analysis of the price differences between the lowest
and next-best quotes from suppliers for more than one-third of all WFP’s 2010 food procurement expenditure
suggests that the import parity approach led to savings of between 23% and 33% (at least $99 million) in the
cost of commodities.
