Abstract: | Marine Protected Areas (MPAs) have been hailed worldwide as vehicles toward sustainable development (SD) in coastal zones.
The prominent model by which MPAs operate is through a comanagement approach, a shift from traditional top-down management.
This paradigm shift must be reviewed continuously to evaluate its social and ecological impacts, thereby allowing adaptive
management. We evaluated the perceived impacts of the Cogtong Bay Mangrove Rehabilitation Project (CBMRP; Philippines) by
using 12 perception indicators categorized into 3 comanagement impact criteria (equity, efficiency, and sustainability). We
also collected 16 contextual attributes of each respondent to determine the correlates of perceived impacts. Our results showed
that there were significant improvements in all indicators under the efficiency criterion but mixed impacts in the equity
and sustainability criteria. Access to resource and household income (equity) and fisheries abundance (sustainability) were
perceived to have decreased during the last 15 years and were not expected to improve in the future. Stepwise multiple regression
analysis showed that the asymmetries of the perceived impacts of the CBMRP were principally caused by disparities in perceptions
by gender and by location (Candijay and Mabini). This highlighted the importance of cross-scale institutional linkages between
Cogtong Bay municipalities to systematically address baywide management issues. Our results further demonstrated the necessity
of integrating gender issues into the evaluation of MPA impacts to ensure a robust evaluation. Finally, we recommend that
a rigorous evaluation of MPAs using a common set of impact indicators should be encouraged to allow comparison of studies
both spatially and temporally. |
