This paper presents a counterfactual approach of fishing households' profitability and vulnerability after the setting up of a marine and coastal protected area (MPA). By using the DID method (Difference-in-Differences), this approach is a comparison of average change in outcome over time for the treated group (fishing households with a main fishing ground adjacent to the MPA) and for the control group (fishing households with a main fishing ground remote from the MPA). From a dataset made up of 183 fishing households in Betenti Islands (Saloum, Delta, Senegal) surveyed twice (one year before the MPA's setting up and six years after it) and divided in two geographical strata, the main result is the applicability and confirmation of the value of a counterfactual approach to assess the positive effect of proximity with a MPA on fishing households' income and vulnerability, independently of fishing productive assets and conditions, and of any change that have affected them during the period taken in consideration. This counterfactual assessment should help to calibrate the necessary investments and to adapt the functioning of a MPA but also to target adequate mitigation and compensation measures for the non-beneficiary households. specialized Marine and coastal protected area Impact assessment Counterfactual approach Fishing profitability Household vulnerability SENEGAL 040 036 021 Ocean and Coastal Management 155 113-125 2018 0964-5691 https://www.documentation.ird.fr/hor/fdi:010072507 10.1016/j.ocecoaman.2018.02.009 0964-5691 [F B010072507] https://www.documentation.ird.fr/hor/fdi:010072507 https://www.documentation.ird.fr/intranet/publi/2018/04/010072507.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-05-04 2023-07-11 fdi:010072507 fre
