  abstract = {{S}tudies of landscape dynamics in protected areas often rely exclusively on remotely-sensed data, leading to bias by neglecting how local inhabitants, who often have a long history of interaction with their environment, perceive and structure the landscape over time. {U}sing a socio-ecological system ({SES}) approach in a forest-swamp-savannah mosaic within the {B}as-{O}gooue {R}amsar site in {G}abon, we assess how human populations participate in landscape dynamics over time. {W}e first conducted a remote sensing analysis to produce a land-cover map representing the biophysical dimension of the {SES}. {T}his map is based on pixel-oriented classifications, using a 2017 {S}entinel-2 satellite image and 610 {GPS} points, that categorized the landscape in 11 ecological classes. {T}o study the landscape's social dimension, we collected data on local knowledge to understand how local people perceive and use the landscape. {T}hese data were collected through 19 semi-structured individual interviews, three focus groups and 3 months of participant observation during an immersive field mission. {W}e developed a systemic approach by combining data on biophysical and social dimensions of the landscape. {O}ur analysis shows that in the absence of continued anthropic interventions, both savannahs and swamps dominated by herbaceous vegetation will experience closure by encroaching woody vegetation, leading to eventual biodiversity loss. {O}ur methodology based on an {SES} approach to landscapes could improve the conservation programs developed by {R}amsar site managers. {D}esigning actions at the local scale, rather than applying one set of actions to the entire protected area, allows the integration of human perceptions, practices and expectations, a challenge that is more than essential in the context of global change.},
