Puzzling regarding change in prices, size of dozens and reject rates is that HAP made claims in 2005 almost identical to those of Haiti Hope project claims in 2014 and 2015.
Quoting directly from the HAP 2005 evaluation,
Field interviews indicated that ten years ago producers were paid four gourdes for a dozen mangos, and a “dozen” was defined as 18 to 20 fruits. Currently, producers have been receiving 35 gourdes per dozen with the dozen defined as 14 fruits. HAP technical assistance and training in producer harvest and handling significantly reduced export factory rejects, and therefore also reduced the exporter’s need to “discount” the number in a dozen. (HAP 2005; p 6)
HAP and Haiti Hope are by no means alone. Organizations making very similar claims about recently changing percentage of rejects and size of dozens (and in much the same language) include,
- AVSF (Agronomist and veterinary without Borders; see AVSF, undated)
- ORE (http://www.oreworld.org/)
- Mercy Corps (see TaiwanICDF 2012)
- USAID/WINNER (2014a)
- OXFAM (2014; see Fuller-Wimbush, Danielle and Cardyn Fils-Aimé 2014)
- IICA, Concern and the EU (see EU 2014)
- ID (Initiative Developpment with ADEMA; see ID 2015)
- World Vision (undated but after 2010)
