However, its use to inform local management is scarce, largely due to the need for fine-grained spatial data representing ecosystem threats that can assess impacts at a local scale. Here, we applied the cumulative impact assessment framework to Moorea's coral reef, French Polynesia to inform the ongoing revision of the island-wide marine spatial management plan. We combined high spatial resolution data on 11 local anthropogenic pressures and four ecological components with expert vulnerability assessments. Results revealed that the entire reef is impacted by at least four pressures: coral reef fisheries, agriculture, land use change and urbanization. These activities together contribute to 87% of the overall cumulative impact. Most importantly, land-based activities contribute to more than half (52%) of the overall impact. Other high-impact activities, such as reef-based tourism, remain very localized and contribute little to the overall human impact. These findings show that by focusing solely on reef-based activities, the current management plan misses critical sources of impact. Not considering land-based activities in the management may lead to decisions that could fail to significantly lower cumulative human impact on the reef. This study demonstrates how operationalizing the cumulative human impact framework at a local scale can help managers identify key leverage points likely to yield improved ecological outcomes. specialized Cumulative effect assessment Threat maps Human impacts Land-based pressures Coral reefs French Polynesia POLYNESIE FRANCAISE MOOREA PACIFIQUE 021 020 096 787 147339 [11 ] 2021 0048-9697 https://www.documentation.ird.fr/hor/fdi:010082208 10.1016/j.scitotenv.2021.147339 0048-9697 [F B010082208] https://www.documentation.ird.fr/hor/fdi:010082208 https://www.documentation.ird.fr/intranet/publi/2021-08/010082208.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-08-31 2025-02-24 fdi:010082208 fre
