Abstract

Senegal's mango production and export industry have experienced remarkable growth, contributing CFAF 8 billion to the economy and generating nearly 20,000 jobs, with women comprising half of the workforce. However, this success is threatened by fruit fly infestations, which can result in potential losses of up to 100% of production. The WAAPP Program, implemented from 2011 to 2013, aimed to combat this issue in Senegal. This research assesses the impact of adopting these innovative technologies on mango losses in Senegal using the ESRM method. The data used come from a survey of 491 mango producers in the Niayes area, including 227 beneficiaries and 264 non-beneficiaries. The findings reveal that adopting one or two technologies leads to significant increases in losses, although to a lesser extent for those adopting two technologies. In contrast, adopting combinations of at least three technologies resulted in a 26% reduction in fruit fly losses for beneficiaries and 27% for non-beneficiaries. However, this difference was not statistically significant. With only 20% of producers adopting three or more technologies, it is crucial to intensify efforts in awareness, training, and facilitating access to technologies for producers. This will not only strengthen the gains made but also secure this economically vital sector.

Key words: Adoption, fruit fly control technologies, impact, endogenous regime shift model, mango losses, Senegal.
