  abstract = {{A} study of the pollen content and organic matter of a 6 m long core recovered from the gallery forest alongside the tributary of {L}ake {P}etpenoun, not far from its mouth ({NW} {C}ameroon, 5 degrees 38 ' 29.3 {N}, 10 degrees 38 ' 43.1{E}, 1120 m asl) doc-uments the evolution of the << {G}rassfields region >> over the last millennium. {T}he exceptional rate of accumulation of the sedimentary series, where the last millennium is 5 m thick, allows to differentiate two distinct periods. {B}e-tween 900 and 1420 {CE}, the coring site was located under lake water, reflecting the expansion of the lake under humid environmental conditions during the {M}edieval {C}limate {A}nomaly ({MCA}). {T}he coring site then gradually dried up from 1420 {CE} onward, during the {L}ittle {I}ce {A}ge ({LIA}). {T}hen, in 1850 {CE}, modern conditions were estab-lished. {D}uring the {LIA}, the lake edge moved about 140 m downstream of the coring site due to drying conditions. {T}he date of 1420 {CE} corresponds to a major event that affected not only local hydrological conditions but also regional vegetation. {T}he collapse of pollen production shows the general degradation of the landscape due to increased drought conditions.},
