  abstract = {{N}atural floating objects ({NLOG}s) are a major component of the habitat of pelagic species. {S}ince the 1990s, the number of floating objects in the open ocean has increased greatly as a result of the introduction of drifting fish aggregating devices ({DFAD}s) by the industrial tropical tuna purse seine vessels. {T}hese changes, and their potential impacts on the species that associate with floating objects, remain poorly understood. {I}f the habitat modifications induced by {DFAD}s have been recently characterized and quantified, the impact of other human activities on the number of floating objects is poorly studied. {R}elying on lagrangian simulations at the scale of the whole {I}ndian {O}cean, from 2000 to 2019, we assess the potential modifications of the pelagic surface habitat that could originate from forest cover change and climate variations. {W}e develop several scenarios, based on coastal and river forest cover, precipitations and river discharge, to simulate densities of {NLOG}s. {O}ur results suggest no significant increase in average {NLOG} densities in the ocean and highlight important regional and seasonal variations of these densities driven by both forest cover change and precipitations. {T}hese preliminary findings underscore the limited understanding of this critical element of pelagic species habitat. {T}herefore, there is pressing need to intensify monitoring efforts for pelagic species habitat and raise awareness about potential impacts of habitat modifications on tuna and other pelagic species.},
